Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a drinking water purifier used in general households.

[Conventional technology]

As this type of conventional vessel, there is one in which a small overcylinder filled with granular activated carbon as a material is connected to a faucet of water supply and water that has passed through an activated carbon layer is used.

[Problems to be solved by the invention]

However, the above-mentioned conventional ones have a problem that impurities adhered to the material inside the excess cylinder are proliferated by various bacteria when not in use, and the water that has passed through this material is rather contaminated. If the material becomes dirty in this way, it can be cleaned by backwashing, etc., but with the conventional one, the structure is difficult to clean, especially in general households, and the material becomes dirty and clogged. When it is done, it is disposable.

[Means for solving problems]

Therefore, the present invention makes it possible to easily wash and regenerate contaminated and clogged materials in general households, and the gist of the invention is to fill an excessive cylinder made of transparent material with granular material, A through hole to the water faucet is opened at the bottom of the excess cylinder, and a hollow stirring shaft with stirring blades is provided around the central shaft of the excess cylinder, and the hollow portion of the stirring shaft is provided. Is opened to the outside on the lower surface of the excess cylinder, the hollow portion of the stirring shaft is communicated with the upper portion of the material layer, and an operation handle is attached to the upper end of the stirring shaft.

[Action]

The water purifier according to the present invention is configured as described above,
By connecting to the tap pipe of tap water, tap water rises through the material layer from the bottom of the overcylinder and is passed, and the tap water passed through the hollow part of the stirring shaft and flows down from the bottom of the overcylinder for use. Can be used for When the material is contaminated or clogged due to use, the state of the material can be checked at a glance because the overcylinder is transparent. Therefore, in such a case, the material can be washed by flowing the water and rotating the stirring shaft using the operation handle to stir the material, and it can be always used in a clean state and is hygienic. Hereinafter, the invention will be specifically described with reference to the drawings.

〔Example〕

In the figure, reference numeral 1 is a cylinder made of a transparent material, 2 is a granular material such as activated carbon, 3 is a supporting floor of the material and a large number of small holes 3a.
Has been established. Reference numeral 4 is a stirring shaft made of a hollow pipe, which is supported by the excess cylinder so as to be rotatable on the central axis of the excess cylinder 1, and a large number of stirring blades are provided on the outer periphery thereof.
4a is provided, the lower end of which projects from the lower surface of the over-cylinder 1 and the hollow portion is opened outside the over-cylinder. Reference numeral 4b is a small hole for liquid water collection provided in the stirring shaft, and is provided at the upper layer portion of the material 2. Reference numeral 4c is a net wound around the small hole for collecting liquid.

Next, reference numeral 5 is an operation handle for rotating the stirring shaft 4, reference numeral 6 is tap water inlet, reference numeral 7 is a switching cock, reference numeral 8 is tap water pipe, and reference numeral 9 is a mounting screw. The water purifier configured as described above is attached to the tap water pipe 8 as shown in the figure, and the tap water is introduced into the overcylinder 1 by the tap 7 so that the tap water passes through the material layer 2 and the stirring shaft 4 is hollow. It is possible to obtain overwater from the section. Then, when the material discolors or the outflow of the water becomes poor after being used for a long time in this way, the material layer is loosened by stirring the material 2 with the operation handle 5 to separate the impurities. At the same time, the contaminants can be washed away by injecting tap water. In other words, the clogging of the material layer can be eliminated by a simple operation. Especially, in this invention, the material cylinder is made of transparent material, so the condition of the material layer can be seen at a glance and early cleaning is possible. Therefore, the life of the material can be maintained and it can be used hygienically.
Further, when the stirring operation is performed for cleaning, since the stirring shaft 4 is provided on the central axis of the overcylinder 1, it is possible to stir the whole material layer, and tap water is passed upward while ascending the material layer. Since it is a flow type, the stirring operation can be performed with an extremely light force.

[Effect of device]

As described above, the water purifier according to the present invention eliminates the drawbacks of the conventional water purifier of this kind, and in particular, the present invention can easily see at a glance how the material is contaminated and easily clean it in a general household. It can be used hygienically and can be used hygienically, and also has great economic advantages as compared with the conventional disposable ones.
