Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage device for a toilet water storage tank, that is, a drainage device for supplying flush water from a water storage tank to a toilet bowl.

[0002]

2. Description of the Related Art A conventional drainage device for a water storage tank for a toilet is provided with a drainage port at the bottom of a water storage tank for supplying flush water to a toilet bowl, and a valve element seated openably and closably on the drainage port is provided. , The pressure of the drainage flow flowing down from the drainage port is connected to the operation lever provided on the upper surface or the side surface of the water storage tank via a chain, and when the operation lever is rotated, the valve body is pulled up to a predetermined height. Keeps the valve open, and flushes the water in the water storage tank to flush the toilet bowl.

[0003]

As described above, since the float valve body is physically pulled and opened by the operation lever installed in the water storage tank, there is a problem of limitation of the installation position of the operation lever and mechanical noise. However, it is difficult for the user of the toilet to operate while sitting on the toilet seat, and the operation lever has to be grasped directly by hand, which is unsanitary. There is a method in which a motor is attached to the position of the operation lever, and the rotation of the operation lever is used to move the operation lever. Although this solves the problem of the operation position of the operation lever, it has problems of durability and mechanical noise. Was not resolved.

The present invention has been made to the drainage device for a water tank for a toilet as described above. First, the operation lever, which is unfavorable in terms of aesthetics and hygiene, is removed from the water tank, and instead an electric switch is used. An object of the present invention is to provide a drainage device for a water tank for a toilet, which is convenient, hygienic, and quiet because a switch is installed at an arbitrary position in a toilet room and a drainage operation is performed by an electric operation.

[0005]

In order to solve the above-mentioned problems, a drainage device for a toilet water storage tank operated by an electromagnet of the present invention has an opening at the bottom of a water storage tank for supplying flush water to a toilet bowl. While increasing the buoyancy of the circular float valve body that sits freely up and down with respect to the drainage port, the permanent magnet having a magnetic force exceeding the buoyancy and the iron core of the corresponding electromagnet prevent the circular float valve body from floating. Since it is installed at an appropriate position, the valve body that cannot be levitated even if buoyancy is generated due to water supply is generated by the magnetic force of the same magnetic pole as that of the permanent magnet in the iron core of the electromagnet to increase the attractive force of the permanent magnet. By converting it into a repulsive force, it is levitated and drained.

[0006]

According to the above-mentioned means, the water pressure in the water storage tank disappears after the drainage is completed, and the float valve body is seated in the water discharge outlet by its own weight, and at the same time, it is installed in the water storage tank by the permanent magnet alone or by the magnetic force of both of them. It attracts to the iron core of the electromagnet to form a strong closed valve state. Even if the water supply is started again and the water level in the water storage tank reaches the height exceeding the float valve body, the float valve body maintains the forced seating state where it cannot float because of the magnetic force exceeding its buoyancy, but the permanent magnet attracts it. By generating a magnetic force with the same pole as the permanent magnet in the coil of the iron core that is present, the attractive force of the magnetic force that forcedly seated the float valve element changes to repulsive force, and the float valve element moves the drainage port by its buoyancy and repulsive force. It is drained by opening when it floats away.

[0007]

Since the present invention is constructed as described above, the drainage device for a water tank for a toilet operated by an electromagnet is an electrical operation different from the conventional mechanical operation using an operating lever or chain. Therefore, there is no limitation on the installation position of the switch, and it can be installed in a sanitary position that is easy to use even for physically handicapped people and sick people, and construction is also simple. In addition, since it has no mechanical parts, it has excellent durability and there is no mechanical noise, and the device is quiet to operate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to the drawings showing the embodiments. FIG. 1 shows an essential part of a low tank type water storage tank equipped with a drainage device for a toilet water storage tank which is operated by an electromagnet according to an embodiment of the present invention.

The water tank A is provided with a ball tap faucet, which is a water supply valve, on one side of the upper part, and the float A4 extending from the faucet moves up and down as the water level changes to open and close the faucet. Therefore, it is a mechanism that supplies a required amount of water to the water storage tank A every time the toilet is used and always stores a predetermined amount of water. A water supply pipe 13 connected to a toilet is connected to the lower part of a drainage case 10 'fitted in the bottom opening of the water storage tank A, and an overflow pipe 12 of a predetermined length that stands upright in the water storage tank is connected to the side. A circular float valve body 3 is seated on the drainage port 10 by connecting the base portion, a guide bar 5 attached to the upper portion of the valve body rises vertically, and the tip is between the overflow pipe 12 and the inner wall of the water storage tank A. Since the extended and fixed guide ring 7 is fitted and inserted, when the valve body floats in the opening, it stops by hitting the guide ring 7.
It is the upper limit of levitation.

FIG. 2 is a vertical cross-sectional view of the main part of FIG. 1, and as shown in the figure, the circular float valve body 3 is a hollow sphere having a sufficient buoyancy and is seated on the drainage eye at the bottom of the water storage tank. The part is bulged to increase the contact surface with the drainage port, and the permanent magnet 2 is fitted at an appropriate position of the bulging part that comes into contact with the iron core of the electromagnet 1 provided at the drainage port when seated, The lower end of the bulging part of the circular flow valve body is provided with a guide bar 5'having a flat elliptical cross section extending downward so that the position and the direction of the drainage port do not shift when seated by descending after draining. It is inserted into the guide ring 7'fixed at. The upper edge of the drainage port is covered with a ring-shaped material 11 having a double-convex cross-section to ensure the valve is closed, and the degree of close contact between the drainage port and the circular float valve body is increased.

FIG. 3 shows another embodiment in which the mounting positions of the electromagnet and the permanent magnet are changed, and the permanent magnet 2a is provided at the tip of the guide bar 5 rising vertically from the circular float valve body 3a.
Is attached and the electromagnet 1a is fixed at the position of the guide ring 7, and as in the above case, the permanent magnet and the electromagnet are brought into contact with each other at the position where the circular float valve body is seated at the drain port, and as shown in the figure. Even if the water level in the water storage tank exceeds the circular float valve body, the permanent magnet 2a alone or the permanent magnet 2a
Since the mutual attraction force between the electromagnet 1a and the electromagnet 1a exceeds the buoyancy of the valve body, the valve is in the forced seated valve closed state. By connecting the electrode to the coil of the electromagnet 1 ′ so that a magnetic force having the same polarity as that of the permanent magnet is generated, the attractive force changes to a repulsive force, and the valve body floats away from the drainage port and opens.

FIG. 4 shows another embodiment according to the fourth aspect of the present invention, in which a guide arm 6 is extended from the overflow pipe 12 and a fulcrum of the guide arm 6 is placed at a predetermined height of the overflow pipe to move up and down. That is, the posture control is performed at the time of water supply and drainage of the circular float valve body 3b attached to the tip. Further, during water supply, the permanent magnet 2b attached to the guide arm 6 and the electromagnet 1b extending from the bottom of the water storage tank
Drainage port 10 of the float valve body by contact with and sucking
However, since the electrode to the electromagnet generates a magnetic force having the same polarity as the permanent magnet when draining, the guide arm 6 is released from the suction, and the float valve body 3 floats due to its buoyancy. However, the drain outlet opens.
