の安定化が計られている。 FIG. 3 is an explanatory cross-sectional view mainly showing an example of the switching valve 38. The casing 40 of the switching valve 38 has five ports 41, 42, 43, 44, 45.
is provided, and the port 41 is connected to the flow path 3 in the handle 33.
2 and the port 42 are connected to the first nozzle 36 via a flow path 46, and the port 43 is connected to the second nozzle 37 via a flow path 47, respectively. The ports 44 and 45 communicate with each other through a flow path 48. 49 is a first
Normally, port 4 is opened by the force of spring 50.
1 and port 42, and port 41
When a water pressure higher than a predetermined level (in this example, 50 kg/cm 2 or higher) is introduced, it slides overcoming the bias of the spring 50, and the ports 41 and 42 are communicated with each other.
51 is a second valve body that operates integrally via the first valve body 49 and the valve rod 52, and when the first valve body 49 responds to the water pressure from the port 41, it opens normally in conjunction with this. It acts to close port 43. Note that when water is supplied from the port 41, water pressure is applied to the first valve body 49, and at the same time water is supplied to the second valve body through the flow path 48.
Water pressure is also applied to the first valve body 51 in a direction that offsets this, but since the pressure receiving surface of the first valve body 1 is formed to be wider, the pressure difference acting on both valve bodies is used to operate the water pressure. do. On the other hand, these valve bodies 49, 51
Once the body moves, the back surface of the second valve body 51 receives water pressure in a direction that adds to the pressure received by the first valve body 49, which acts as a state-holding force. 2 ) Lower water pressure (approximately 40
Kg/cm 2 ) or below, it will not return to normal operation, and is designed to stabilize its operation.

Spray water in a wide direction. On the other hand, the solenoid valve 26 as the pressure reducing means
When the valve opens, the pump discharge pressure is low (approximately 20
Kg/cm 2 ), the valve bodies 49 and 51 return to their normal state, and the second nozzle 37 discharges low-pressure water that expands laterally along the brush 34.

使用ができると云つた多くの利点がある。 As mentioned above, in this example, the car is rinsed using high-pressure spray cleaning to remove sand, mud, etc., and then the brush is used. It is programmed so that it will not be attached. In addition, if cleaning with a brush is performed while accompanied by a high-pressure spray, the repulsion force against the object to be cleaned will be too strong due to the spray pressure, making brushing difficult. In addition to making it easy to apply, the spray pressure acts appropriately to prevent excessive friction between the brush and the object to be cleaned, ensuring both protection of the cleaning surface and good brush operability. There is. Furthermore, the brush has an angle with respect to the handle of the nozzle device, so it can easily wash the roof of a car, and waxing can be done using a brush that doubles as a low-pressure spray, so the wax can be applied evenly and effectively. Furthermore, since the brush is attached to the handle side rather than the nozzle, there are many advantages such as the fact that water does not splash towards the user when using the brush, making it more comfortable to use.

バネ定数の設定となつている。 FIG. 6 is an explanation of the main parts of another embodiment of the nozzle device 30. This embodiment includes a single nozzle 71 connected to the flow path 32 in the handle 33 of the nozzle device 30 via a hose 70. This nozzle 71 is fixed to an arm 73 that is rotatably attached to a fixed piece 72 that is integral with the handle 33.
The arm 73 has an elongated hole 75 that engages with a protrusion 74 provided on the fixed piece 72, thereby restricting the range of rotation of the arm 73. Therefore,
When water is sprayed from the nozzle 71, a reaction force is generated in the nozzle 71 that causes the water to recede in the direction opposite to the water spray direction, and the moment of this force causes the arm 73 to rotate within a range regulated by the elongated hole 74. Reference numeral 76 denotes a spring that biases the arm 3 in a direction that resists the moment of the reaction force of the water discharge, and when the electromagnetic valve 26 is opened for low-pressure spraying, the nozzle 71 is maintained in a normal state and the brush 3 is
4, and during high-pressure spraying with the solenoid valve 26 closed, the moment of water discharge reaction force overcomes the bias of this spring 76 and the arm 73 rotates.
The spring constant is set.

る。 Therefore, in the above example, when the solenoid valve 26 is opened during low-pressure spraying, the nozzle 71 discharges water in the direction along the brush 34, which is convenient for brush cleaning.
On the other hand, during high-pressure spraying, as the arm 73 rotates, the nozzle 71 sprays water in a direction nearly square to the handle 33, facilitating spray cleaning. Further, compared to the above-mentioned embodiment in which water is sprayed by switching between the first and second nozzles, there is an advantage that only one nozzle is required, and the structure is simple and can be manufactured at low cost.

に合つた効果的使用ができる。 This invention is constructed as described above, and includes at least a nozzle device for discharging cleaning water pumped by a pump, and a means for adjusting the water supply pressure of the cleaning water, and the nozzle device includes a cleaning brush and a means for adjusting the water supply pressure. Since the nozzle is equipped with a nozzle that changes the direction of the cleaning water discharge, it is possible to use either traditional spray cleaning, which uses high-pressure water, or brush cleaning, which uses water at low pressure to make it easier to use the cleaning brush. It can perform a wide range of cleaning depending on the purpose, and if used in combination, such as removing sand and mud with high-pressure spray and removing remaining dirt with brush cleaning, there is no need to worry about damaging the items being cleaned. It is possible to achieve a much higher cleaning effect than before. In addition, the nozzle is configured so that its direction changes depending on the cleaning water pressure.
When spraying at high pressure, water can be sprayed forward for easy spray cleaning, and at low pressure, water can be sprayed in the direction along the brush for easy brush cleaning, making it possible to use it effectively depending on the application.
