BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier used for purifying tap water, and more particularly to an overflow type water purifier through which water passes from bottom to top.

[0002]

2. Description of the Related Art Conventionally, a water purifier of a type that allows tap water to pass from the top to the bottom has been widely known, but in recent years, an overflow type that allows the water to pass from the bottom to the top has come to be adopted. It is coming. This is because the passing water flows evenly in the filter medium and the contact time with the filter medium is prolonged, so that the purification is enhanced.

[0003]

However, the overflow type filtration method has a problem in that a loosening gap is formed in the stored filter medium, causing disorder in the filter layer and water channels to reduce the filtration effect. . In view of the above-mentioned problems in the prior art, the present invention provides a water purifier capable of keeping the filter medium in a stable state and preventing the disturbance of the filter layer and the occurrence of water channels, and enhancing the water purification effect. That is the purpose.

[0004]

Therefore, according to the present invention, a tubular container body, a discharge pipe connected to the upper end of the container body, a filter medium housed inside the container body, and a lower end of the container body are provided. A water purifier comprising a connected injection pipe and a lid for closing the lower end of the container body, wherein a spring body for urging the filtering material upward is provided between the filter and the lid. Is.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a partially broken perspective view of a water purifier according to the present invention, and FIG. 2 is a partial cross-sectional side view of the water purifier according to the present invention. Figure 1
Also, as shown in FIG. 2, a substantially cylindrical container body 1 made of metal is provided with a bottom lid 2 at its lower part through an O-ring 3, and the bottom lid 2 is screwed to the container body. 1 can be closed. Here, the bottom cover 2 is provided with an injection pipe 2b which communicates with the bottom cover central hole 2a from its side surface, and the tap water is connected to the end thereof so that tap water can be injected into the container body 1. Has been done.

Inside the container body 1, a filter layer is formed by accommodating, in order from below, a filter medium, such as a silas sand 4, an antibacterial activated carbon 5, and a silas sand 6 via a nonwoven fabric 7. Here, the shirasu sand is shirasu porous glass crushed into sand, and has the function of filtering and adsorbing impurities mixed in tap water. In addition, the antibacterial activated carbon 5 is refined into a coarser grain than shirasu sand, and it filters and adsorbs impurities mixed in tap water,
Has the effect of decolorizing and deodorizing tap water.

Above and below the inside of the container body 1, there are provided an upper partitioning plate 8 and a lower partitioning plate 9 which are covered with a non-woven fabric on the surface of the container to allow tap water to flow therethrough so as to be slidable on the inner circumference of the container body 1. The filter layer is sandwiched from above and below. A coil spring 10 is provided below the lower partition plate 9, and the lower end of the coil spring 10 is fitted into the central hole 2a of the bottom cover 2 to urge the lower partition plate 9 upward so that the filter layer is constantly pressed from below. It is supposed to do.

A closed upper lid portion 11 is integrally formed at the upper end of the container body 1, and a discharge pipe 12 is provided at the center of the upper lid portion 11 so as to communicate therewith, and the tap water rising through the filter layer is discharged. It is made possible.

Next, the method of use and the operation of this embodiment will be described. First, tap water is connected to the outer end of the injection pipe 2b, the tap of the tap is opened, and tap water is discharged. The discharged tap water is injected into the container body 1 via the injection pipe 2b and the central hole 2a. The tap water injected into the container body 1 once fills the space formed between the bottom lid 2 and the lower partition plate 9, and enters the filter layer to rise. The tap water that has entered the filter layer first passes through the shirasu sand 4, whereby impurities mixed in the tap water are filtered and adsorbed. Next, ascending and passing through the antibacterial activated carbon 5, the residue that has not been filtered and adsorbed by the shirasu sand 4 is filtered and adsorbed, and the tap water is decolorized and deodorized. Next, the tap water passes through the shirasu sand 6 to further filter and adsorb impurities. The impurities mixed in the tap water as described above are completely filtered and adsorbed by the filter layer to become clean and safe water, which is discharged through the discharge pipe 12.

In the process of using the water purifier for a long time, the container body 1 is affected by the water pressure of passing tap water or an external impact.
When the filter medium housed inside is loosened, the looseness is eliminated by pressing the coil spring 10 from below, so that a gap between the filter medium and a water channel can be prevented. Further, since the filter layer is constantly pressed and sandwiched by the upper partition plate 8 and the lower partition plate 9, the filter layer is not disturbed and can be always maintained in a stable state. This allows tap water to flow evenly through the filter layer and have a sufficient contact time with the filter material.

[0011]

As described above, according to the present invention, the cylindrical container body, the discharge pipe connected to the upper end of the container body, the filter medium housed inside the container body, and the lower end of the container body are connected. In the water purifier consisting of the injection pipe and the lid that closes the lower end of the container body, since the spring body that urges the filtering material upward is provided between the filtering material and the lid, the stored filtering material There is an excellent effect that it is possible to prevent the generation of gaps due to the loosening of the filter, the disturbance in the filter layer and the generation of water channels, and it is possible to always keep the filter medium in a stable state. Therefore, the passing water has an excellent effect that it can flow evenly through the filter medium and have a sufficient contact time with the filter medium to enhance the water purification effect.
