The front and rear spray units 60 , 60 ′ are provided with a liquid supply pipe 100 . The liquid supply pipe 100 is provided with a liquid inlet 101 and a liquid outlet 103 .

The liquid inlet 101 is a portion through which water received from the liquid chamber 301 to be described below is introduced, and the liquid outlet 103 is a portion through which the water introduced from the liquid inlet 101 is discharged. In addition, the center flow path pipe 110 and the turning flow path pipe 120 to be described below are provided between the liquid inlet 101 and the liquid discharge port 103 .

The length to diameter ratio of the liquid supply pipe 100 is preferably 5:1 to 10:1. This is to ensure that water flows uniformly while moving along the liquid supply pipe 100 .

The liquid supply pipe 100 includes a center flow path pipe 110 and a turning flow path pipe 120 .

The cross-sectional area of the liquid inlet 101 is smaller than the cross-sectional area of the one end 110a of the center flow pipe 110 . That is, the width of the liquid inlet 101 is smaller than the width of the one end 110a of the center flow pipe 110 . And the cross-sectional area of one end 110a of the center flow pipe 110 is smaller than the cross-sectional area of the center 110c of the center flow pipe 110 .

That is, the width of the center 110c of the center flow pipe 110 may be the same as the width of the liquid discharge port 103 , or may be formed to have a smaller width or a larger width.

Meanwhile, the cross-sectional area of the liquid inlet 101 is smaller than the cross-sectional area of the orbiting flow path pipe 120 . That is, the width of the liquid inlet 101 is smaller than the width of the one end 120a of the orbiting flow path pipe 120 .

The cross-sectional area of one end 120a of the orbiting flow passage pipe 120 is smaller than the cross-sectional area of the center 120c of the orbiting flow passage pipe 120 , and the cross-sectional area of the center 120c of the orbiting flow passage pipe 120 is the liquid discharge port 103 .

That is, the orbiting flow path pipe 120 may be radially disposed with respect to the center flow path pipe 110 . Here, the orbiting flow path pipe 120 may be formed in a curved shape. This is to allow the water to spread widely through the orbiting flow path pipe 120 while being stagnant for a predetermined time.

The cross-sectional area of the center 110c of the center flow pipe 110 may be larger than the cross-sectional area of the center 120c of the orbiting flow pipe 120 . This is to allow water to smoothly escape through the center flow path pipe 110 rather than the turning flow path pipe 120 .

In this embodiment, the orbiting flow pipe 120 is formed in a shape corresponding to each other, but is not necessarily limited thereto. For example, the orbiting flow path pipe 120 may be formed to have different lengths. In this way, the angle at which the liquid is sprayed and the direction in which it flows can be varied.

According to the liquid supply pipe 100 configured in this way, a left and right flow is induced as water flows in from the liquid inlet 101 and passes through the center flow path pipe 110 and at the same time as the orbiting flow path pipe 120 passes, and this flow is As the water flows and spreads left and right inside the center flow pipe 110 through the liquid outlet 103, the spray angle of water can be expanded.

In addition, since water passes through the other end 110b of the center flow path pipe 110 and the other end 120b of the orbiting flow path pipe 120 and is discharged to the liquid discharge port 103, that is, the center flow path pipe 110 is Since the passing water flows greatly while meeting with the water passing through the orbiting flow path pipe 120 at the liquid discharge port 103, they collide with each other to cause atomization, and the spray angle can be increased.

In this embodiment, the cross-sectional area of the spray port 203 is formed to be larger than the cross-sectional area of the connector 201 .

Meanwhile, the liquid inlet 101 communicates with one side of the receiving tank 300 . The receiving tank 300 may be integrally formed with the liquid inlet 101 .

A liquid chamber 301 is formed inside the accommodation tank 300 . Pressurized water may be accommodated in the liquid chamber 301 .

As shown in FIG. 2 , a solenoid valve B may be installed in the front and rear water pipes 50 and 50 ′. The solenoid valve B serves to open and close the front and rear water pipes 50 and 50'. The operation of the solenoid valve B may be controlled by a controller.

As shown in FIG. 3 , a pressure sensor 500 may be provided inside the connector 201 of the spray nozzle 200 . The pressure sensor 500 serves to measure the pressure of water passing through the connector 201 to generate a pressure measurement value.

On the other hand, the operation of the front and rear spray units (60, 60') can be controlled by the controller.

In this embodiment, when the pressure measurement value is lower than the preset value when compared with the preset value, the controller controls the solenoid valve (B) to stop the supply of water to the accommodating tank 300 and receive only compressed air at the same time It may be supplied to the tank 300 . Therefore, when the connector 201 or the spray hole 203 of the spray nozzle 200 is blocked, only compressed air is supplied to prevent the spray nozzle 200 from being blocked.
