Description

[Detailed explanation of the invention] [Purpose of the invention] (Industrial application field) The invention is a device that can be attached to a water faucet in a general household, for example, to purify tap water or flush it as raw water. Regarding water purifiers.

(Prior art) Conventionally, for example, as shown in Japanese Utility Model Application Publication No. 60-165090, a cartridge (activated carbon storage chamber), and by the vertical movement of the faucet tube,
A structure in which tap water flows out as raw water from an annular water sprinkling body provided below the outer body, or purified water flows out from an outflow tube provided on the lower surface of the cartridge by passing it through the cartridge. Water purifiers have been proposed.

(Problems to be solved by the invention) In the water purifier described in the above-mentioned Japanese Utility Model Publication No. 60-165090, an outflow pipe for outflowing purified water is provided directly on the bottom surface of the cartridge (activated carbon storage chamber), so it is particularly long. If the water purifier is not used for a period of time, the water in the activated carbon layer will disappear. When the activated carbon layer loses moisture, bacteria breed there, which is extremely unhygienic. Therefore, when using the water purifier again, a considerable amount of water must be flushed to flush out the bacteria in the activated carbon layer, but since this extra water must be used, it is difficult to use even sterile drugs. It was hot.

Furthermore, in the water purifier described above, since the gap between the outer shell (container body) and the cartridge serves as a water path, the outer shell is likely to swell and deform due to water pressure. In order to prevent such deformation, the outer body must be deformed using a material with high strength, resulting in an expensive water purifier.

This invention aims to solve these problems, and can prevent the proliferation of bacteria in the activated carbon layer.
To obtain a water purifier which is therefore hygienic and economical, prevents deformation of the container body etc. due to water pressure, does not require molding the container body etc. from a material with high strength, and can be made at low cost. The purpose is to

A raw water communication hole is formed to communicate with the hole, and a raw water communication hole is formed on the upper surface of the cylindrical part of the container body, facing the inflow hole and opened and closed by a valve part formed at the upper part of the switching body. , the switching body moves downward between the cylindrical part of the vessel and the switching body to form a raw water flow gap that communicates the raw water flow hole with the raw water communication hole when the raw water flow hole is opened; forming a purified water distribution hole on the upper circumferential surface of the cylindrical portion of the container body, which communicates with the purified water outflow hole when the switching body moves upward and closes the raw water distribution hole, and which is closed when the switching body moves downward; Inside the vessel, surrounding the cylindrical part, there is an activated carbon storage chamber that communicates from above to below with the inflow hole at the top, and a purified water communication hole formed on the lower surface of the activated carbon storage chamber. A water purification chamber that communicates with the activated carbon storage chamber and the water purification hole through a gap between the cylindrical portion, and a raw water chamber that communicates with the raw water outflow hole and with the raw water communication hole of the cylindrical portion. The sections are formed sequentially.

(Function) When the water purifier of the present invention allows tap water to flow as raw water, the switching body is moved downward to open the raw water flow hole that was blocked by the valve part, and purify the water in the cylindrical part. At the same time as blocking the flow hole, the raw water flow hole is communicated with the raw water flow hole through the raw water flow gap, and the water flowing from the inflow hole is passed through the raw water flow hole, the raw water flow gap, and the raw water flow hole.
Through the raw water communication hole and the raw water chamber inside the container, the raw water flows out in a shower shape from the multiple small hole-shaped raw water outlet holes on the bottom surface. The raw water flow hole of the cylindrical part is closed by the valve part, and the purified water flow hole is communicated with the purified water outlet hole of the switching body, and the water flowing from the inflow hole is transferred to the activated carbon storage chamber and the purified water communication hole.

There is.

Next, the operation of this embodiment will be explained.

Switching between flowing tap water as raw water and flowing purified water is performed by rotating the lever body 42. That is, this lever body 4
2 relative to the vessel body 1, the protrusion 54
moves within the inclined groove 49 of the switching cylindrical body 41, and as the protrusion 54 moves, the switching cylindrical body 41 slides up and down within the cylindrical portion 2 along the slope of the inclined groove 49. When raw water flows out, the switching cylindrical body 41 is positioned downward, and when purified water flows out, the switching cylindrical body 41 is positioned upward.

When the switching cylindrical body 41 is positioned downward, the valve portion 44 is separated from the raw water flow hole 5 to open the raw water flow hole 5, and the closing protrusion 45 is opened.
closes the purified water communication hole 6, and the annular protrusion 48 further moves away from the raw water communication hole 7, thereby opening the raw water communication hole 7. The water flowing in from the faucet 33 passes through the inflow hole 27, the raw water flow hole 5, the raw water flow gap 50, the raw water flow hole 7, and the raw water chamber 12 in this order, and then flows out from the raw water outlet hole 4.

At this time, since the raw water outflow hole 4 is formed in the shape of a plurality of small holes, the raw water flows out in a shower shape. Therefore, especially when this water purifier is used in a sink or the like, water does not splash, which is convenient.

On the other hand, when the switching cylindrical body 41 is positioned downward,
That is, when purified water flows out, as shown in the drawing, the valve portion 44 closes the raw water flow hole 5, and
The purified water communication hole 6 is superimposed on the through hole 46, and the annular protrusion 48 further closes the raw water communication hole 7. The water flowing in from the inflow hole 27 flows into the activated carbon storage chamber 20 via the inflow path 30 and the filter 8.
There, odors and the like are adsorbed by the activated carbon 22 and the water is purified. Furthermore, the purified water is filtered through filter 1.
6. The purified water flows out from the purified water outlet hole 43 through the purified water communication hole 18, the purified water chamber 19, the gap 21, the purified water distribution hole 6, the through hole 46, and the interior of the switching cylinder 41.

At this time, in the inflow path 30, the throttle protrusion 2a
Since the flow rate is restricted, the pressure inside the activated carbon storage chamber 20 does not become excessively high, and deformation of the container body 1 is prevented.

By the way, as shown in the drawing, the portion of the water path with a small cross-sectional area is the gap 50 between the cylindrical portion 2 and the switching cylindrical body 41 when raw water flows out.
and a raw water chamber 12 facing the raw water outflow hole 4, and when purified water flows out, the inlet passage 30 on the upper surface side of the cylindrical part 2, the support piece 14 of the support body 13, and the partition plate 1.
1 and the gap 50 between the support cylindrical portion 15 of the support body 13 and the cylindrical portion 2. These supporting cylindrical portion 15, cylindrical portion 2, and switching cylindrical body 41 have a smaller diameter than the vessel body 1, and are fitted with each other, so they have high structural strength. Deformations such as 1 rarely occur. Therefore, since there is no need to mold the container body 1 etc. from a material with such high strength, the cost can be reduced.

The activated carbon storage chamber 20 also communicates with the purified water outflow hole 43 via the purified water communication hole 18 on the lower surface and the purified water circulation hole 6 on the upper part of the cylindrical part 2.
is located at the same height as the upper part of the activated carbon storage chamber 20, so water is maintained in the activated carbon storage chamber 20 even when not in use. Therefore, the proliferation of various germs within the activated carbon 22 is prevented, which is sanitary. Moreover, it is economical because there is no need to drain extra water when reusing it.

[Effect of idea]

According to the present invention, the purified water communication hole on the lower surface of the activated carbon storage chamber and the purified water outflow hole on the lower surface of the switching body are formed at the upper part of the cylindrical part, that is, at the same height as the upper part of the activated carbon storage chamber. Since communication is provided through the holes, water is always stored in the activated carbon storage chamber even when not in use, which prevents the growth of bacteria in the activated carbon layer, making it hygienic.
It is economical as there is no need to drain excess water during reuse, and when purified water flows out, the water path within the container is mainly from the activated carbon storage chamber, the water purification chamber below, and the activated carbon storage chamber to the center of the container. When raw water flows out, it is the gap between the tubular part and the switching body fitted inside it, and the raw water chamber facing the raw water outflow hole on the bottom of the vessel. Therefore, the container body etc. are not easily deformed by water pressure, and there is no need to mold the container body etc. from a material with high strength, so that an inexpensive water purifier can be obtained.
