The present invention relates to a toilet cleaning tank such as a low tank.
[0002]
[Prior art]
Conventionally, a toilet cleaning tank for storing cleaning water for cleaning a flush toilet is known. As shown in FIG. 6, the low tank which is an example of this toilet bowl washing tank is provided with the outer tank 91 which stores washing water inside, this outer tank 91 has the opening 91a above, and a water stop valve in the bottom part. As a float valve 92. Further, the opening 91a is closed by a lid member 93 in which a hand basin is integrated. An attachment hole 91b is provided in the upper side surface of the outer tub 91, and a ball tap 94 is provided in the attachment hole 91b. The ball tap 94 is provided with a water supply pipe 94a extending to the bottom of the outer tub 91 and an arm 94b connected to a valve body (not shown) that opens and closes the water supply pipe 94a. It is connected to a float 94c that floats with the washing water inside. The outer tub 91 is provided with a lever 95 that opens and closes the float valve 92.
[0003]
In this low tank, the user swings the lever 95 to open the float valve 92 and discharges the wash water in the outer tub 91 to the flush toilet. Thereby, the filth of the flush toilet can be washed away. Thereafter, when the water level of the washing water is lowered, the float 94c is lowered and the arm 94b is moved downward. Thereby, the valve body of the ball tap 94 is opened, and tap water is automatically supplied into the outer tub 91 through a water supply pipe 94a from a pipe (not shown) connected to the ball tap 94. Thereafter, when the water level of the washing water rises to a certain level, the valve body of the ball tap 94 is closed, the supply of tap water is stopped, and the low tank returns to the original standby state.
[0004]
[Problems to be solved by the invention]
However, in the above-mentioned conventional low tank, the outer tub 91 and the lid member 93 are usually made of earthenware, so that the dimensional accuracy is inferior and the lid member 93 is heavy. It is simply placed on 91a. For this reason, there is a slight gap between the outer tub 91 and the lid member 93, and when the cleaning water is stored in the outer tub 91, sound leaks to the outside through the gap, causing discomfort to the user and the like. Easy to give.
[0005]
In this regard, it is conceivable that the gap between the outer tub 91 and the lid member 93 is completely eliminated by a sealing means such as rubber packing or a sealing agent. By doing so, it is considered that the sound of the washing water stored in the outer tub 91 does not leak to the outside and does not give the user unpleasant feeling.
[0006]
However, when such a measure is taken, the inside of the low tank becomes negative pressure when the washing water is discharged, so that the washing water is not easily discharged to the flush toilet. For this reason, there is a concern about the cleaning ability of filth. The above defects also exist in toilet cleaning tanks other than the low tank.
[0007]
The present invention has been made in view of the above-described conventional situation, and solves the problem of providing a toilet flushing tank that does not give a user an unpleasant feeling due to sound and has a high ability to wash filth of flush toilets. It is an issue to be done.
[0008]
[Means for Solving the Problems]
The toilet flushing tank of the present invention includes an outer tub that has an upper opening and has a water stop valve at the bottom, stores washing water that can wash the flush toilet, and a lid member that closes the opening. In the toilet bowl,
[0009]
Sealing means for sealing the inside is provided between the opening and the lid member, and the outer tank or the lid member is provided with an intake valve that performs intake when the cleaning water is discharged. Features.
[0010]
In the toilet bowl cleaning tank of the present invention, a sealing means is provided between the opening and the lid member, and since this sealing means seals the inside, the sound generated when storing the washing water is leaked to the outside. Can be prevented. For this reason, it does not give a user a discomfort.
[0011]
Further, in this toilet bowl cleaning tank, an intake valve is provided in the outer tub or the lid member, and since this intake valve performs intake when the cleaning water is discharged, a volume of air substantially equal to the volume of the discharged cleaning water is generated. It flows into the toilet flushing tank through the intake valve. For this reason, the inside of a toilet bowl washing tank does not become negative pressure, and washing water is easily discharged to a flush toilet bowl. For this reason, it is excellent in the cleaning ability of filth.
[0012]
In the toilet bowl cleaning tank of the present invention, it is preferable that the outer tub has mounting holes on both sides where the ball tap can be fixed, and the intake valve is provided on the mounting hole opposite to the mounting hole where the ball tap is fixed. If it is like this, since the attachment hole which fixes a ball tap and an intake valve can be replaced | exchanged according to the position of piping near a toilet bowl washing tank, the freedom degree of construction becomes large.
[0013]
The lid member can include a resin lid body and a weight fixed to the lid body. In this case, the lid main body can be easily manufactured and the manufacturing cost can be reduced. On the other hand, the lid member is increased in weight and the sealing effect by the sealing means is increased. In this case, the weight is preferably removable from the lid body. In this case, the lid body and the weight can be manufactured separately, and the lid member can be easily assembled in the factory, so that further reduction in manufacturing cost can be realized. On the other hand, a lid member can be assembled at the time of construction of the toilet bowl cleaning tank, and cost reduction before shipping can be realized.

The ball tap 4 is provided with a water supply pipe 4a extending to the bottom of the outer tub 1 and an arm 4b connected to a valve body (not shown) for opening and closing the water supply pipe 4a. It is connected to a float 4c that is levitated by washing water. The outer tub 1 is provided with a lever (not shown) that opens and closes the float valve 2.
[0020]
As shown in FIG. 3, the intake valve 5 includes a cylindrical member 51 made of synthetic resin and a valve body 52 made of synthetic resin as shown in FIG. 4.
[0021]
As shown in FIG. 3, the cylindrical member 51 has an inner cylindrical portion 51a on one side formed in a square cylindrical shape. As shown in FIG. 5, the inner cylindrical portion 51a is set inside and the intake valve 5 is attached. Will be. Further, as shown in FIG. 3, the outer cylinder portion 51b on the other side of the cylinder member 51 has a cylindrical shape, and as shown in FIG. Will be attached. A pair of brackets 51c are formed on one side surface of the inner cylinder portion 51a so as to face each other and extend in the axial direction, and each bracket 51c is cut out of a shaft hole 51d having a substantially circular cross section. Further, when one side surface on which both brackets 51c are formed is positioned upward, the end surface of the inner cylinder portion 51a is slightly inclined upward. On the end surface of the inner cylinder portion 51a, a hemispherical convex portion 51g is provided so as to protrude from a position farthest from each bracket 51c. A flange 51e is formed between the inner cylinder part 51a and the outer cylinder part 51b. A male screw 51f is formed on the peripheral surface of the outer cylinder portion 51b.
[0022]
On the other hand, as shown in FIG. 4, the valve body 52 has a substantially rectangular thin plate shape, and a shaft portion 52a extending in parallel with the one side is formed on one side. The shaft portion 52a is loosely fitted into the shaft holes 51d.
[0023]
The intake valve 5 is attached to the attachment hole 1c of the outer tub 1 as follows. First, as shown in FIG. 5, a cylindrical member 51 having a valve body 52 is prepared, and an outer cylinder portion 51 b of the cylindrical member 51 is placed in the outer tub 1 while one side surface on which both brackets 51 c are formed is positioned upward.

In this state, the rubber flat packing 55 and the washer 53 are fitted into the outer cylinder portion 51b protruding outward from the outer tub 1, and the synthetic resin nut 54 is screwed into the outer cylinder portion 51b.
[0024]
In the low tank configured as described above, when the internal pressure tends to be negative in order to discharge the internal wash water to the flush toilet, the valve body 52 of the intake valve 5 swings upward due to the external air pressure. For this reason, the cylinder member 51 communicates the atmosphere and the inside of the raw tank, and air having a volume substantially equal to the volume of the discharged cleaning water flows into the raw tank through the cylindrical member 51. For this reason, the inside of a low tank does not become a negative pressure, wash water is suitably discharged to a flush toilet, and by extension, exhibits an excellent ability to clean filth.
[0025]
When a certain amount of washing water is discharged, the float valve 2 is seated and the washing water is stopped from being discharged. As a result, in this low tank, the internal pressure does not tend to be negative, and the valve body 52 of the intake valve 5 is seated on the end surface of the cylindrical member 51. Thereafter, the float 4c is lowered in the inner tank 6, and the arm 4b is moved downward. Thereby, the valve body of the ball tap 4 is opened, and tap water is automatically supplied into the outer tub 1 through a water supply pipe 4 a from a pipe (not shown) connected to the ball tap 4.
[0026]
At this time, in this low tank, the lid member 3 has a weight 3b and is heavy, and the packing 3e is provided in a portion of the lid member 3 that contacts the opening 1a. Can be prevented from leaking to the outside. For this reason, it does not give a user a discomfort. In addition, since the valve body 52 of the intake valve 5 secures a minute gap between the convex member 51g and the cylindrical member 51, the remaining air in the low tank is discharged to the outside through the gap.
[0027]
Thereafter, when the water level of the cleaning water rises to a certain level, the valve body (not shown) of the ball tap 4 is closed, the supply of tap water is stopped, and the low tank returns to the original standby state.
[0028]
Further, in this low tank, the outer tub 1 has mounting holes 1b and 1c for fixing the ball tap 4 on both sides, and the intake valve 5 is provided in the mounting hole 1c opposite to the mounting hole 1b to which the ball tap 4 is fixed. Therefore, the mounting holes 1b and 1c for fixing the ball tap 4 and the intake valve 5 can be replaced according to the position of a nearby pipe, and the degree of freedom in construction can be increased.
[0029]
Furthermore, in this low tank, since the weight 3b can be detached from the lid body 3a, the lid body 3a and the weight 3b can be manufactured separately, and the lid member 3 can be easily assembled in the factory. Therefore, further reduction in manufacturing cost can be realized. On the other hand, since the lid member 3 can be assembled by a user or the like during construction of the low tank, in that case, it is possible to reduce the cost before shipping.
