Abstract
A cleaner for the inside of a water tank utilizing a siphoning action is provided, in which the interior of a water passage (24) between an upstream-side one-way valve (Vu) and a downstream-side one-way valve (Vd) is pressurized or depressurized by a pressing operation of a suction operation tool (A) provided in a bent connecting part between a main body portion (1) and a grip portion (2) of a suction pipe (P), and water-tank water of the main body portion (1) is sucked into the suction pipe (P). This enables waste material such as leftover food within water-tank water to be sucked up together with dirty water by a very simple operation.
Claims3
A cleaner for the inside of a water tank in which water-tank water within a water tank (V) is sucked up by a siphoning action and drained outside the water tank (V), the cleaner comprising
- a suction pipe (P) formed from a linear main body portion (1) and a grip portion (2) bendingly connected to the main body portion (1),
- a flexible water-guiding pipe (17) connected to the outer end of the suction pipe (P),
- an upstream-side one-way valve (Vu) provided at an appropriate place within the main body portion (1) and only permitting the flow of water from the suction pipe (P) to the water-guiding pipe (17),
- a downstream-side one-way valve (Vd) provided within the grip portion (2) and only permitting the flow of water from the suction pipe (P) to the water-guiding pipe (17), and
- a suction operation tool (A) provided in a bent connecting part between the main body portion (1) and the grip portion (2) and pressurizing or depressurizing the interior of a water passage (24) between the upstream-side one-way valve (Vu) and the downstream-side one-way valve (Vd).

- a downstream-side one-way valve (Vd) provided within the grip portion (2) and only permitting the flow of water from the suction pipe (P) to the water-guiding pipe (17), and
- a suction operation tool (A) provided above the suction pipe and pressurizing or depressurizing the interior of a water passage (24) between the upstream-side one-way valve (Vu) and the downstream-side one-way valve (Vd),
- the suction operation tool (A) being formed from an operation tube (20) provided above an upper wall of the suction pipe and having an operation chamber (25) positioned above the water passage (24) within the suction pipe (P), a press button (21) slidably fitted into the operation chamber (25) via a seal ring (22) and projecting outside the operation tube (20), and a return spring (23) provided within the operation tube (20) and urging the press button (21) toward the outside.
