At the time of use, the handle portion 47 raises the handle portion 473, grips it, and lifts it.

Next, the locking mechanism will be described. The lock mechanism is a mechanism that restricts the upward movement of the tank body 40 in order to prevent the tank body 40 from becoming lighter and separating from the saucer portion 6 due to the outflow of detergent due to use. In this embodiment, the locking mechanism includes a handle portion 47.

FIG. 7 is a perspective view showing an example of a locking mechanism that locks the handle portion 47 of the tank 4 to the tank accommodating portion 5. 8 (a) to 8 (c) are diagrams showing a procedure for locking. FIG. 8A shows a state before being locked, FIG. 8B shows a state during locking, and FIG. 8C shows a locked state.
The lock mechanism locks the tank body 40 and moves upward to regulate the opening of the on-off valve 43 while the tank body 40 is housed in the tank housing portion 5. The lock mechanism is composed of a lock protrusion 471c of a handle portion 47 serving as an engaging portion and a groove portion 550 formed on the support surface 55.

As shown in FIG. 7, the groove portion 550 is formed on the side surface of the recess 50 of the tank accommodating portion 5 in the vicinity of the opening. In particular, the groove 550 has a hook-shaped notch that extends downward along the side surface of the recess 50 from the edge of the opening of the tank housing 5 and bends on one side in the width direction. The groove portion 550 has a first groove portion 551 and a second groove portion 552.

The first groove portion 551 is a semicircular recess that supports the large diameter portion 471b of the shaft portion 471 of the handle portion 47, has a size one size larger than the outer diameter of the large diameter portion 471b, and the large diameter portion 471b has a larger diameter portion 471b. It is formed in a rotatable size.

The second groove portion 552 is formed outside the first groove portion 551, that is, on the side away from the recess 50 of the tank accommodating portion 5. As shown in FIG. 7, the second groove portion 552 is continuously formed from the first groove portion 551, extends from the upper side to the lower side, and protrudes only on one side in the width direction as shown in FIG. 8 (a). It is formed in a hook-shaped notch. Specifically, the second groove portion 552 is composed of a strip-shaped portion 552a and a quarter-circle portion 552b.

The band-shaped portion 552a is a substantially rectangular notch formed so as to extend downward from the support surface 55.
The quarter circle portion 552b is a quarter circular notch formed at the lower end of the strip-shaped portion 552a. In the quarter circle portion 552b, one side of the longitudinal edge of the strip 552a extends continuously and linearly from the strip 552a, and the other side of the longitudinal edge of the strip 552a extends in the direction of extending the strip 552a. It bends in a direction substantially orthogonal to form a protruding portion 552c. A quarter circle portion 552b is formed by drawing an arc from the protruding end of the protruding portion 552c toward the lower end of the one-sided edge of the strip-shaped portion 552a.

As shown in FIG. 8A, the handle portion 47 is grasped and the lock protrusion 471c of the shaft portion 471 connected to the base end side of the extension portion 472 is moved downward in the first groove portion 551 of the groove portion 550. Let me.

As shown in FIG. 8B, the handle portion 47 stops when the lock protrusion 471c reaches the lower end of the first groove portion 551. At this time, since the lock protrusion 471c has a substantially quarter-circular peripheral edge, the lock protrusion 471c slides and rotates along the quarter-circle portion 552b of the second groove portion 552. The handle portion 47 tilts from the state raised from the tank main body 40 by the own weight of the extension portion 472 and the handle portion 473. At this time, the relationship between the large diameter portion 471b of the shaft portion 471 and the first groove portion 551 of the groove portion 550 is such that the handle portion 473 is tilted by about 80 degrees in the side view of the tank body 40 and stops. It is preferably larger than the large diameter portion 471b, but when the user releases the handle portion 473, the handle portion 473 completely rolls over and enters the first recess 51 of the tank body 40. May be good.

After that, as shown in FIG. 3, the user pushes the handle portion 473 of the handle portion 47 to fit the handle portion 473 into the gap between the tank body 40 of the tank 4 and the first recess 51 of the tank accommodating portion 5. When inserted, the lock protrusion 471c moves along the curve of the quarter circle portion 552b.

As shown in FIG. 8C, when the lock protrusion 471c engages with the quadrant 552b of the groove 550, even if the tank 4 tries to rise upward, it abuts on the protrusion 552c of the quadrant 552b. Since it is locked, the tank 4 is restricted from moving upward. By tilting the extending portion 472 and the handle portion 473 in this way, the handle portion 47 is locked, and the base end side of the handle portion 47 is engaged with the peripheral edge (side surface near the opening) of the tank accommodating portion 5. It fits.

FIG. 8 is a schematic diagram of a locking mechanism according to another embodiment. In another embodiment, the configuration of the handle portion 473 of the handle portion 47 is different from the above embodiment.

The handle portion 473 is a position where the handle portion 47 is raised so as to be separated from the tank main body 40, and the upper surface of the handle portion 473 is inclined upward from one end portion in the width direction toward the other end portion in the side view, and the top portion 478. The angle θ is an acute angle.

According to another embodiment, when the handle portion 473 is inclined, even if the handle portion 47 stands upright with respect to the upper surface of the tank body 40, the rear upper surface cover 303 is used after accommodating the tank 4. Since the rear upper surface cover 303 hits the inclined surface of the upper surface of the handle portion 473, the handle portion 47 is pushed and collapses. When the handle portion 47 is tilted, the lock protrusion 471c of the shaft portion 471 engages with the second groove portion 552 and is locked as in the above-described embodiment.

The configuration of the lock mechanism is not limited to the above-described embodiment as long as it restricts the upward movement of the tank body 40. In the lock mechanism, by accommodating the tank body 40 in the tank accommodating portion 5, the tank body 40 and the tank accommodating portion 5 are engaged with each other, or some regulating member is arranged above the opening of the tank accommodating portion 5. As a result, the movement of the tank body 40 may be restricted.
