There is a problem that an unfavorable situation arises in terms of hygiene, and the spray nozzle must be airtightly connected to the detergent tank via a hose when spraying the detergent, so that the detergent should be sprayed far from the detergent tank. In such a case, there is a problem that a long pipe line is required.

  The structure disclosed in Patent Document 2 is a structure in which air is used as a medium to pressurize the liquid, so that a situation where the liquid and water are not mixed does not occur, but the water pressure from the water pipe is always increased. It is necessary to make the air pressurizer sturdy, and a large water hammer pressure generated when the tap of the water pipe is suddenly closed acts on the air pressurizer. There has been a new problem that troubles such as breakage are likely to occur.

By operating the operation valve, either the water pipe or the drain path communicates with the water pressure chamber of the pressurized tank. By being configured, when the water pressure chamber in the pressurized tank and the water pipe are communicated, the air in the pressurized tank can be pressurized using the water pressure, and the pressurized tank In the state where the water pressure chamber and the drain path communicate with each other, the water in the water pressure chamber can be drained well through the drain path, and both pressurization of the pressurization tank and drain drainage can be operated with one operation valve. .

  The operation valve is always urged so that the water pressure chamber of the pressurization tank and the drain passage communicate with each other, so that the operation valve is operated only when it is desired to pressurize the pressurization tank. Water pressure can be applied to the pressurized tank, and drainage drainage is otherwise applied, so the pressure is released and the pressurized tank is always at atmospheric pressure. Normally, water pressure is not applied to the pressurized tank. It is possible to reduce the mechanical burden on the pressurized tank and prevent the pressurized tank from being damaged.

  In addition, the liquid tank is configured to be able to be separated from a pipe line communicating with the liquid tank while keeping the pressurized air in the air chamber hermetic, so that the liquid tank is pressurized inside. Since the air can be separated while being kept airtight, the liquid tank can be freely carried independently, and the liquid can be sprayed well even at a distant place.
