The toilet device 1 is detachably attached to a toilet body 10 and includes a detergent tank A for storing detergent mixed in flush water supplied to a bowl 11 provided in the toilet body 10. - 特許庁

The detergent tank A has a storage space 21 inside, a tank portion 20 having a replenishment port 22 at the top, and a container lid 30 detachably attached to the replenishment port 22 . The container lid 30 includes a lid portion 31 capable of freely closing/opening the replenishment port 22 , a take-out portion 40 projecting downward from the center of the inner surface of the lid portion 31 and having a flow path 41 , and a side of the outer surface of the lid portion 31 . and a delivery portion 50 having a channel 51 projecting in the direction and communicating with the take-out portion 40 . A filter 43 is provided in the channel 41 of the extracting section 40 .

Next, the toilet device 1 shown in FIG. 1 and the detergent tank A detachably housed in the toilet device 1 will be described in detail.

A toilet body 10 of the toilet device 1 includes a bowl 11, a peripheral wall 13 surrounding the bowl 11 from the sides, a toilet seat 12, a toilet lid (not shown), and the toilet seat 12, the toilet lid, and the bowl 11. and a body rear portion 14 which is closed. The toilet seat 12 and the toilet lid can be opened and closed by turning.

A trap device (not shown), pipes (not shown), etc. are arranged in the lower part of the main body rear part 14 surrounded by the peripheral wall 13 on the rear side. is provided, and an operating portion 14a with a cover is arranged behind it. 1(a) and 1(b) show a state in which the cover is removed.

Further, a tank housing portion 15 is arranged in a portion that is usually covered with a cover, next to the operation portion 14a. A tank holder 16 is accommodated in the tank accommodating portion 15, and has an accommodating structure in which the detergent tank A is detachably arranged in the tank holder 16. - 特許庁

The tank accommodating portion 15 is open upward when the cover is removed, and the detergent tank A can be taken in and out through the opening. The tank housing portion 15 is formed with a liquid introduction port 15a for feeding the liquid detergent sucked from the detergent tank A by a pump (not shown) into the bowl 11 .

Further, the tank holder 16 is shaped to accommodate the detergent tank A, prohibits the rotation of the delivery portion 50 of the detergent tank A, which will be described later, and introduces the detergent delivered from the delivery portion 50 into the tank accommodation portion 15. It has a tube fixing part 16b that can be guided and fixed to the port 15a. A drain hole 16c is provided in the bottom of the main body 16a of the tank holder 16 so that the detergent leaked from the detergent tank A can be drained.

The detergent tank A has the tank portion 20 and the detachable container lid 30 as described above. The upper surface of the tank portion 20 is provided with a refill port 22 projecting upward in a cylindrical shape and a handle 25 .

A lid portion 31 of the container lid 30 has a cylindrical shape with a downward opening so that it can be closed and locked/unlocked by rotating the lid portion 31 over the replenishment port 22 .

The take-out part 40 has a tubular shape, protrudes downward from the center of the inner surface of the lid part 31 on the storage space 21 side, and a filter 43 is provided at the tip of the flow path 41 of the take-out part 40 . Note that the mounting position of the filter 43 is not particularly limited. The delivery part 50 extends laterally so as to form a substantially right angle with the take-out part 40 so as to protrude from the side surface of the tank. A lead-out portion 52 with a delivery port 53 facing downward is provided on the tip end side of the delivery portion 50 , and the lead-out portion 52 is fixed to the tube fixing portion 16 b of the tank holder 16 .

When the container lid 30 is attached to the tank portion 20 in a closed and locked state, the take-out portion 40 is substantially perpendicular to the inner bottom surface of the tank portion 20 so as to vertically penetrate the storage space 21 of the tank portion 20 . and its tip is arranged to be close to the inner bottom surface.

Therefore, the detergent stored in the storage space 21 is sucked by the pump, first moves upward through the flow path 41 of the take-out portion 40, then passes through the inside of the lid portion 31, and reaches the bent flow of the delivery portion 50. It moves through the path 51 and is delivered from the delivery port 53 to the liquid introduction port 15a below.

As described above, the container lid 30 is configured such that the lid portion 31 can freely change between a state in which the replenishment port 22 of the tank portion 20 is closed and a state in which the replenishment port 22 is opened. It is set as the structure which distribute|circulated through the cover part 31. As shown in FIG. That is, the present detergent tank A is configured such that the replenishment port 22 for detergent replenishment provided in the tank portion 20 also serves as a supply port for supplying the detergent to the bowl 11 .

In this way, the detergent tank A is not provided with a supply port separate from the replenishment port 22 in the tank portion 20, that is, is not provided with a plurality of openings. Therefore, the detergent tank A can be efficiently maintained. Also, the manufacturing cost of the detergent tank A can be reduced. Furthermore, since the tank portion 20 is not provided with a plurality of openings, the possibility of detergent leakage is low.

The lid portion 31 and the replenishment port 22 can be moved relative to each other between the closed lock/unlocked positions by rotating the container lid 30 in a closed state with the lid portion 31 covering the refill port 22 . A fitting structure is provided.

With this fitting structure, the state of the container lid 30 shown in FIG. Reverse operation is possible by rotating operation. 3(a) indicates the direction in which the container lid 30 rotates from the closed lock position to the unlocked position, and the arrow M2 indicates the direction in which the container lid 30 rotates in the opposite direction. be.

As a fitting structure on the side of the tank portion 20 (replenishing port 22 ), fitting protrusions 24 are provided at two locations on the lower portion of the outer peripheral portion of the replenishing port 22 . As shown in FIG. 4(c), the cross section of the fitting protrusion 24 is substantially trapezoidal. The fitting protrusion 24 is formed so as to have a gap with the upper surface of the tank portion 20 . This gap serves as a space into which a protruding piece 34 (see FIG. 4A) of the lid portion 31, which will be described later, enters in the closed locked state. An inclined guide surface 24a (see FIG. 4(c)) is formed on one surface of the fitting protrusion 24 in the rotational direction.

On the other hand, as a fitting structure for the container lid 30 (lid portion 31 ), a fitting receiving portion 32 corresponding to the fitting protrusion 24 is provided on the peripheral wall portion 31 a of the lid portion 31 . The fitting receiving portion 32 includes a fitting window 32a (see FIG. 4A) and an elastic piece 33 (see FIG. 4A) for fitting the fitting protrusion 24 into the fitting window 32a. and at least The state in which the fitting protrusion 24 is fitted in the fitting window 32a is the closing locked state. A more detailed fitting structure will be described later.

Alignment portions 23 and 36 are provided on the tank portion 20 and the container lid 30 for facilitating the fitting operation of the lid portion 31 to the replenishing port 22 . As positioning portions, a mark 36 is provided on the edge of the upper surface of the lid portion 31 on the container lid 30 side, and a protrusion 23 is provided on the outer peripheral portion of the replenishment port 22 on the tank portion 20 side.

A horizontally long notch window 35 is formed in the lower portion of the peripheral wall portion 31 a of the lid portion 31 at a position corresponding to the mark 36 . The positional relationship is such that the protrusion 23 is disposed at one end of the cutout window 35 when the lid portion 31 is placed over the replenishment port 22 by aligning the positioning portions 23 and 36 with each other. In the window space of the cutout window 35 , the projection 23 relatively moves from the closing lock position to the unlocking position and from the unlocking position to the closing lock position by rotating the container lid 30 .

In other words, one end of the cutout window 35 is a covering position for the lid portion 31 and also serves as a stopper when the unlocking operation is performed. On the other hand, when the protrusion 23 moves to the other end of the cutout window 35, the fitting protrusion 24 of the replenishment port 22 and the fitting receiving part 32 of the lid 31 are fitted together to enter a closed and locked state.

Next, the fitting structure between the fitting receiving portion 32 of the lid portion 31 and the fitting protrusion 24 of the replenishing port 22 will be described in detail with reference to FIGS. 4 and 5. FIG.

As shown in FIG. 4A, the fitting receiving portion 32 has a fitting window 32a into which the fitting protrusion 24 is fitted with almost no gap. The fitting window 32a is formed by opening a part of the peripheral wall portion 31a. A protruding piece 34 made of a part of the lower end of the peripheral wall portion 31a is formed below the fitting window 32a, and an elastic piece 33 made of a part of the peripheral wall portion 31a is formed on one side of the fitting window 32a. ing.

The elastic piece 33 acts as an elastic plate-like portion by providing a lateral groove 32b between the elastic piece 33 and the upper peripheral wall portion 31a. The elastic piece 33 is formed thinner than the rest of the peripheral wall portion 31a so as to be more flexible, and has a vertical groove 32c formed at its base. A standby recess 33c is formed on the back side of the elastic piece 33, into which the fitting protrusion 24 is fitted in the unlocked position. Since this standby recess 33c is formed along the entire length of the elastic piece 33 in the vertical direction, the lid portion 31 can be moved upward at this position (unlocked state: FIG. 5(a)). reference). In addition, a lock portion 33a is formed at the tip of the elastic piece 33 and protrudes inward with the surface on the waiting recess 33c side serving as a guide surface 33b.

From this unlocked state, when the container lid 30 is rotated to relatively move the fitting projection 24 in the M2 direction (see FIG. 3(a)), the fitting projection 24 of the replenishment port 22 guides the locking portion 33a. The surface 33b is pressed. Then, the fitting protrusion 24 bends the elastic piece 33 outward while pressing the lock part 33a, and moves relatively to the fitting window 32a through the inside of the lock part 33a (locked state: FIG. 5(b)).

In this locked state, the projecting piece 34 is inserted below the fitting projecting portion 24 of the lid portion 31, so that the lid portion 31 cannot be moved upward. In addition, when the closed locked state is established, the projection 23 which is the positioning portion on the side of the tank portion 20 relatively moves to the other end portion of the cutout window 35 .

Further, when the fitting protrusion 24 is relatively moved in the M1 direction (see FIG. 3A) by rotating the container lid 30 from the closed and locked state, the guide surface 24a of the fitting protrusion 24 moves the locking portion 33a. press . Then, the fitting projection 24 bends the elastic piece 33 outward while pressing the lock portion 33a, and moves relatively to the standby recess 33c through the inside of the lock portion 33a (unlocked state: See FIG. 5(a)).

In this unlocked state, the container lid 30 can be removed. In addition, when the unlocked state is established, the projection 23 which is the positioning portion on the side of the tank portion 20 relatively moves to one end portion (original position) of the cutout window 35 .

Such a fitting structure is formed at two locations as shown in FIG. 5, and they perform fitting (blocking lock)/fitting release (unlock) operations at the same time.

According to this fitting structure, mutual positional movement between closure locking/unlocking can be carried out by a one-touch operation by rotating the container lid 30 . Further, since the positioning portions 23 and 36 are provided, the covering position and the removing position of the container lid 30 (lid portion 31) can be recognized at a glance, and efficient operation can be performed.

Next, the internal structure of the container lid 30 will be described with reference to FIG.

The container lid 30 of the detergent tank A has a structure in which an enclosing wall 37 is provided around the projecting base portion 42 of the take-out portion 40 on the inner surface of the lid portion 31 with a predetermined space therebetween. The surrounding wall 37 is a portion that enters further inside (on the storage space 21 side) of the replenishing port 22 inside the peripheral wall portion 31a when the container lid 30 is placed over the replenishing port 22 of the tank portion 20. As shown in FIG. The surrounding space of the projecting base portion 42 surrounded by the surrounding wall 37 adheres to the outer peripheral surface of the take-out portion 40 when the container lid 30 is removed and the container lid 30 is turned upside down as shown in FIG. 6(a). A liquid pooling portion 38 is formed in which the remaining detergent that has been removed falls along the outer peripheral surface and accumulates there.

Since the surrounding wall 37 is a portion arranged inside the replenishment port 22 (on the storage space 21 side) when the container lid 30 is placed over the replenishment port 22, the detergent accumulated in the liquid pooling portion 38 does not flow out to the outside. is returned to the storage space 21.

Since the container lid 30 is provided with the surrounding wall 37 in this manner, there is almost no possibility that the residual detergent running down the take-out portion 40 will reach the vicinity of the inner side of the peripheral wall portion 31a due to the surrounding wall 37 acting as a weir. . Of course, there is no possibility that the residual detergent will reach the outer surface of the peripheral wall portion 31a. That is, with such a configuration, it is possible to prevent the upper end of the replenishment port 22 and the outside thereof from being soiled with the detergent. In addition, since the residual detergent accumulated in the liquid reservoir 38 is returned to the original storage space 21, waste of the detergent can be reduced.
