Description

[Detailed description of the invention] This invention is used to filter tap water, etc., by uniformly dispersing and flowing the supplied water into a filtration tank containing filter media and adsorbents, so that it can be filtered and cleaned with high efficiency over a long period of time. The invention relates to a filter that uses a filter.

BACKGROUND ART Many devices have been proposed to purify supplied water using a filter tank containing a filter material, an adsorbent, and the like.

However, if emphasis is placed on the purification effect, the amount of water purified will decrease, and if emphasis is placed on the amount of water purification, the purification effect will be reduced.

In addition, when used for a long time, local clogging occurs, resulting in a significant decrease in both the amount of purified water and the purification ability.

This idea allows the supplied water to flow through the filtration tank in an evenly distributed manner, thereby maintaining good cleanliness and filtration performance over a long period of time.

An embodiment of this invention will be described below with reference to the accompanying drawings.

The sealing peripheral wall 2 of the filtration tank 1, the water supply port 3, and the water supply port 3
A purified water inlet 6 and a downward water discharge lower are provided above the water flow chamber 4 of the base body 5 provided with the water flow chamber 4 that communicates with the water flow chamber 4, and a purified water outlet 8 that fits into the purified water inlet 6 is provided below. A filter medium 9 and an adsorbent 10 are suitably accommodated in the filter tank 1, and a required number of radial slots 12 are formed on the top surface 11 of the filter tank 1, and radial protrusions are formed inside the top surface so as to sandwich the slots 12. A strip 13 is formed, and a small protrusion 14 is formed on the upper surface of the top surface 11.

The sealed chamber 2 is screwed onto the peripheral wall 2 and the annular backing 15 is sandwiched therebetween.
The small protrusion 14 is pressed by the top surface of the cover 16 formed with the filtration tank 1, and the filtration tank 1 is hermetically fixed on the base 5. In addition, a water introduction hole 17 is opened at an appropriate position in the water passage chamber 4, and a The leaked water fills the sealed chamber 24.

The water filling the sealed chamber 24 rises through the gap a between the cover 16 and the filtration tank 1, passes through the gap between the top surface 11 of the filtration tank formed by the small projections 14, and the cover 16, and enters the radial grooves. 12 into the filtration tank 1.

In this case, it is distributed between the radial protrusions 13 and 13 on the inside of the top surface,
It passes through the filter material 9 and the adsorbent 10 and is purified, enters the water flow chamber 4 from the lower purified water outlet 8, and is discharged from the water discharge lower.

The water supply port 3 is rotatably attached to the base 1, and the water supply port 18 opened on the side is connected to a knob 19 fixed to the water supply port 3.
By rotating, the water passage chamber 4 is communicated with or shut off, and the amount of water flowing into the water passage chamber 4 can be adjusted by changing the rotation position.

In addition, a valve rod 21 is provided in the water passage chamber 4 that slides within the water passage chamber 4 by the rotation of the rotating piece 20, and the water guide hole 17 is placed in the valve rod 21 at a position where water from the water supply port 3 is blocked. A switching valve 22 is provided that shuts off the water introduction hole 17 when the water supply port 3 and the water flow chamber 4 are opened and the water supply port 3 and the water passage chamber 4 are in communication state, and when there is no need for purification, the water introduction hole 17 is closed by operating the valve rod 21. , the water supply to the filter tank 1 is stopped, water is immediately supplied from the water supply port 3 to the water passage chamber 4, and water is discharged from the water discharge lower.

In addition, numeral 23 in the figure is a known water stiller screwed into the discharge port.

According to this invention, the water flowing into the cover 16 from the water introduction hole 17 as described above flows through the base 1, the peripheral wall 2, and the cover 16.
6, and while rising through the gap a between the filtration tank 1 and the cover 16, the water pressure and flow velocity are equalized over the entire circumference, passing through the gap formed by the small protrusion 14. It flows into the filter tank 1 through the radial slots 12 .

The water flowing into this filter tank is filtered through the radial protrusions 13 on the top surface.
Since the water is uniformly dispersed over the entire surface of the top of the tank, there is no unbalanced flow within the filtration tank, and the cleaning ability of the filter material 9 and adsorbent 10 can be maintained well over a long period of time.
