Description

Water level control device of water storage tank

The present invention is designed to automatically control the water level without using electricity in various drinking water devices, such as water purifier, equipped with a separate tank separate from the main tank and by lever using the principle of the float and lever in the auxiliary tank It is a water level control device of a reservoir tank that installs an open / close valve to control the flow of water in the middle according to the water level.

In general, the water level control includes an electric control method using a sensor and a mechanical control method using buoyancy. The double mechanical control method has a simpler structure, a lower manufacturing cost, and fewer malfunctions and malfunctions than the electric control method. On the other hand, there is a problem that the internal structure of the main body tank becomes dirty due to the installation of a float directly inside the main body tank, which is not good in appearance and sanitary for sanitary reasons. There was a problem that the noise is generated due to the relatively high pressure applied to the water, and since the float is located directly in the body tank, the water subjected to the float control immediately falls into the body tank, and there is a structural disadvantage in which noise is generated.

On the other hand, the applicant of the Utility Model Registration Application No. 94-13418, as the water level in the reservoir tank is raised and lowered together with the buckle in the valve case ascends the lifting body by a magnet built in the upper part of the upper and lower the upper The water level automatic control valve of the water storage tank has been applied for automatically adjusting the water level of the water storage tank by opening and closing the connection passage by the elevating body which opens and closes the central outlet hole of the body. It has a disadvantage that the buoyancy is small and the force blocking the valve hole is small compared to the water pressure, so that the opening and closing operation is not performed reliably. The valve is finally closed by the operation of the magnet by the magnet. These magnetics are difficult to standardize precise product quality during production. The defect rate was high, and the valve body is usually made of iron (Fe), so that rust is generated by contact with water during use, which is not sanitary and also causes a malfunction, and uses a special steel that does not rust. Even if it did not meet the requirements of the desired, there was a disadvantage that only the production cost is expensive.

In addition, in the water level automatic control valve using the applicant's magnetic as described above, when foreign matters such as sila are caught in the opening and closing portion, the sealing operation is not smooth due to the structure of the opening and closing portion, which acts as a factor that impairs the quality improvement of various drinking water devices such as a water purifier. I did.

In addition, the present invention is to make the auxiliary tank containing the sub-ball in the structure where only the existing sub-ball itself is installed to be easily installed in any storage tank by making a single unit through the optimization design, and the buoyancy received from the sub-ball is applied directly to the valve. It is to make sure that the opening and closing operation of the valve is made by doubling the force without making.

In addition, the present invention is to make a quiet opening and closing operation by making the sealing through the line contact in the channel opening and closing the noise generated by the increase in the flow rate when the water level rises.

In order to achieve the above object, the present invention has a means that can be attached to the outside of the body tank to match the water level of the body tank, and the auxiliary tank is connected to the inside of the body tank formed on one side of the lower tank, installed on the top of the auxiliary tank A cover covering the auxiliary tank, a valve installed at a predetermined position of the cover, a buckle installed inside the auxiliary tank and lifting and lowering by buoyancy, and having a lower end fixed to a center of an upper surface of the buoy and having an upper end facing outward.
