Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flush water tank that feeds flush water into the bowl of a toilet bowl.

[Conventional technology]

The flush toilet is either integrally provided with a flush water tank that supplies flush water for discharging waste, or is attached with a wall-mounted corner tank. These wash water tanks have a ball tap disposed between them and the wash water supply source, and have the function of always storing a constant amount of wash water in response to fluctuations in the water level in the tank.

Further, the supply of flush water to the bowl portion of the toilet bowl is performed by opening and closing a drain plug provided in the tank. A rotary lever or button provided on the side wall of the wash water tank is generally used to open and close the drain valve.

[Lesson Z' that the bolter tries to solve.

However, the flush water tank that supplies flush water to the bowl of the toilet bowl and discharges waste remains in a structure that requires manual operation of levers, buttons, etc. for operation, as described above. In other words, since it is a mechanical device in which a drain plug provided in a bottom hole of a washing water tank is connected to a lever with a chain, it cannot be incorporated into an operating section of a sanitary washing device or the like. Therefore, in order to supply cleansing water after using the toilet, it is necessary to extend the vagina toward the cleansing water tank and operate the levers and buttons with your fingertips, just like with conventional flush toilets, and you need to use the sanitary cleansing device that comes with the toilet. It is much less user-friendly than other functional parts. For this reason,
Even if you can comfortably clean and dry your private parts with a sanitary cleaning device,
Only cleaning the toilet bowl requires handling in the same way as conventional products, and there are areas that need improvement from the perspective of added value to the product.

To address these problems, the applicant has already proposed in Japanese Patent Application No. 62-275088 a system in which a rotary lenoid operated by a remote controller is used to drive a drain plug. This has a structure in which the proximal end of an arm with a chain tied to the tip is connected to the rotating shaft of a rotary lenoid, and the arm is rotated by the operation of the rotary lenoid to pull up the drain plug.

However, when the rotorinoid is energized, its rotating shaft rotates instantaneously, causing the drain plug to be pulled upward. For this reason, the impact applied to each member such as the arm, chain, and drain plug when the valve is opened is also increased, creating new problems in terms of strength. Therefore, in order to ensure reliable operation and increase durability, it is necessary to supplement the strength of the members, which inevitably increases costs. Furthermore, if the wall thickness of the member is increased, the mounting strength to the wash water tank itself becomes insufficient, and the design of the wash water tank must also be changed.

Furthermore, in the rotary lenoid, since the solidification angle of the rotating shaft is limited to a fixed angle, it is not possible to set the amount of washing water depending on the degree of opening of the drain plug, unlike the conventional manual handle. Therefore, in order to send an appropriate amount of cleaning water for cleaning, it is necessary to provide at least two rotary solenoids, and there remains a problem in terms of assembly cost due to the increased number of parts.

Therefore, an object of the present invention is to reduce the impact when pulling up the drain plug to eliminate the problem in terms of strength, and to change the rotation angle of the arm so that an appropriate amount of washing water can be sent. .

[Means to solve the problem]

In order to achieve the above object, the cleaning water tank of the present invention connects a ball chain or the like to the drain plug inserted inside, and rotates a spindle disposed through the tank body to achieve the above-mentioned 2.

It is constituted by a rectifier tube 7 provided around the drain tube 6 and an overflow tube 8 provided coaxially with the drain tube 6 so as to be movable up and down. Further, a discharge port 6a is recessed in the lower wall of the drain pipe 6, and a valve seat 6b is formed below the discharge port 6a. And the upper side is a double pipe + 3 structure with an inner pipe 6c
serves as a guide for the overflow pipe 8.

At the lower end of the overflow pipe 8, there is a valve seat 6bI of the drain pipe 6.
: An O-valve body 8a such as a gasket to sit is provided, and a float 8b is integrated in the middle. This float? b1 = is arranged for the purpose of adjusting the valve closing time to ensure the amount of water supply.

The drain plug 5 described above draws the overflow pipe 8 upward to separate the valve body 8a from the valve seat 6b, thereby supplying cleaning water to the ball portion 2al. The movement of the overflow pipe 8 up and down is carried out automatically by a drive device 10 provided on the side wall of the wash water tank 1.

The drive device 10 is fixed to the side wall of the wash water tank 1 by a frame loa, is entirely covered by a casing 10b, and is provided with a synchronous motor 11 as a drive source inside. A clutch bearing 15c is provided on the frame 10a, and a spindle 12 is rotatably attached to the frame 10a, the tip of which protrudes inward from the side wall of the wash water tank 1, and an arm 13 is connected to the tip. This arm 13 has an L-shape extending radially from the center of rotation, and the end of the arm 13 and the overflow pipe 8 are linked by a chain 14, which is an example of a linking member.

Furthermore, the output shaft of the motor 11 and the spindle 12 are provided with a drive@megumi 15a and a driven tooth m15 as a power transmission system, respectively.
b. Further, a clutch case 16 is arranged on the frame 10a, and an electromagnetic coil i6a is housed in the clutch case 16, and the spindle 12 is inserted through the electromagnetic coil 16a. A rotor 17 is integrated with the spindle 12 by a key 17a, and this rotor 1

can be displaced in the axial direction.

That is, as shown in FIG. 4, the base end of the leaf spring 20 is connected to the follower gear 15b by a screw 19, and the tips of two or more legs E20a extending from the center are welded or the like. It is integrated into the armature 18. Under normal conditions, the armature 18 is located at a distance from the rotor 17 as shown in FIG. Move and get close to this. Also, i! ! When the power is stopped, the armature 18 returns to its original state as shown in FIG. 2 by the restoring force of the leaf spring 20. The driven gear gap 15b is fitted onto the outer periphery of the spindle 12 with a slight gap, and has a structure in which the spindle 12 does not rotate even if the driven tooth gap 15b rotates.

Here, in the state shown in FIG. 2, the armature 18 and the rotor 17 are separated from each other, and the spindle 12 remains stationary even if the follower gear i5b rotates. And the electromagnetic coil 16a
When the rotor 17 is magnetized by applying electricity, the armature 18 is attracted toward the rotor 17 and joined thereto. Therefore, the rotation of the subordinate gear 15b is transmitted to the spindle 12 via the armature 18 and the rotor 17, changing the attitude of the arm 13 and pulling the chain 14 upward. As a result, the overflow pipe 8 rises, the valve body 8a separates from the valve seat 6b, and flushing water is supplied to the ball portion 2a, thereby flushing the flush toilet bowl 2. When the electromagnetic coil 16a is no longer energized, the armature 18 returns to its original position due to the elastic deformation of the leaf spring 20.

Therefore, the arm 13 returns to the original water stop position, the valve body 8a is seated on the valve seat 6b, and purified water is supplied into the tank body 1 up to a predetermined water level.

The drawing force from the motor 11 to the spindle 12 is the drive tooth! [15a and driven teeth! 15b, the rotational speed of the spindle 12 can be made warm by appropriately setting the rotational speed of the motor 11 and the ratio of the number of teeth of these gears.

Therefore, there is no momentary large impact on the 6 materials such as 3 sets 14, there is no need to increase the strength of each B material, and even the conventional manual structure can be used without any problems. .

Furthermore, the rotation angle of the 8 force axes of the motor 11 and the electromagnetic coil i6
If the mortar time of a is changed, the rotation angle of the arm 13 is also changed. Therefore, it is easy to reduce the amount of washing water depending on the purpose, and it is possible to send an appropriate amount of washing water for washing.

〔Effect of the invention〕

As explained above, in the cleaning water tank of the present invention, the spindle integrated with the arm for opening and closing the drain valve is rapidly moved by the rotation of the output shaft of the drive tb device, and the arm side is moved rapidly by the electromagnetic clutch mechanism. and the output shaft side is separated. Therefore, the rotation angle of the arm can be arbitrarily changed depending on the rotation angle of the output shaft of the drive device or the energization time of the TL electromagnetic clutch, so a single drive system can perform cleaning suitable for feces and urine. Water can be pumped into the toilet bowl. In addition, by adopting an electromagnetic clutch, the motion relationship between the drive source side and the arm side is broken when the power is not energized, so manual cleaning can be performed in the event of a power outage, and if the power outage occurs during operation, the arm arm Since the water returns to the original water level in the stomach, there is no need to drip cleansing water over the eyes.
