Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a simple water purifier.

(Prior technology) Simple water purifiers that are attached to drinking water outlets such as faucets include those that only have a water purifier container that is installed only when purified water is needed, and those that have a switching valve attached to the water purifier so that the water does not pass through the water purifier container at all times. There is one that dispenses water through a water filter, and when necessary, switches a valve to pass the water through a water purifying agent.

(Problems to be Solved by the Invention) The above-mentioned water purifying agent container alone is troublesome to install and remove, and to store when not in use, and if left unattended, the water purifying agent will be wasted.

Also, those with switching valves and switching channels are larger and therefore more expensive, and also get in the way.

(Means for solving the problem) This invention is a simple water purifier attached to a downward outlet for drinking water, which includes a lid with an inlet opening in the center, and a bowl with an outlet opening in the center and watertight connection to the lid. The shaped body, the lid, and the lid are supported so as to float concentrically in the space within the body, and a circulation channel that runs directly from the inlet to the outlet is formed along the outer surfaces of the ceiling, bottom plate, and peripheral wall, which are water-permeable plates. The ceiling of the container has a dish-shaped weir plate in the center facing the inlet, and water flows radially from the uniform gap between the periphery of this shear plate and the lid. teeth,
This simple water purifier is characterized in that if the water force is strong, the entire amount passes through the water channel, and if the water force is weak, the water passes through the container.

(Function) In the water purifier of this invention, water can be passed through a water purifying agent or not through a water purifying agent using a switching valve, but this can be done by adjusting the water force without using a switching valve. You can adjust the water pressure using the water stop valve handle at the drinking water outlet.

The cylindrical water purifying agent container placed between the lid and the bowl-shaped main body naturally serves as a passageway for the water inside, and also serves as a circulation channel through which the gap between its entire outer periphery, the lid, and the inner surface of the main body passes directly. . The water entering from the inlet in the center of the lid is stopped by a dish-shaped dam on the ceiling of the water purifying agent container, and is radiated in all directions through the uniform gap between the periphery of the dam and the lid.

The way it flies is controlled by the water force,
If the water force is increased, the entire amount will be poured into the circulation channel that flows directly through the water, and if it is weakened, the blown water will fall by gravity onto the water-permeable ceiling plate of the water purification agent container, where it will come in contact with the water purification agent inside the container and be purified. It descends and exits to the outlet.

(Embodiment) Figures 1 and 2 show an embodiment of this invention attached to a downward outlet A for drinking water via an intermediary rubber pipe B, in which the above-mentioned lid is 1, the bowl-shaped body 2, and a water purifying agent. The container is 3, its ceiling is 3a, the bottom plate is 3b, the surrounding wall is 3c,
The inlet in the center of the lid is 4, the outlet in the center of the main body is 5, the dish-shaped weir plate in the center of the container ceiling is 6, the activated carbon that is the water purifying agent is C, and the circulation channel that runs directly along the outer periphery of the container 3 is D. .

The ceiling 3a and bottom plate 3b of the water purifying agent container 3 are perforated plates, and the granular water purifying agent C is packed inside.
This is a well-known device in which water purifies water while it descends from the ceiling 3a. There is no separate mechanism for supporting this by floating it concentrically inside the lid 1 and main body 2, and the peripheral wall 3c is extended downward to form the legs 7, which are provided with a number of through holes 8 so as not to block the detour channel D. It's dawning. The leg part 7 is fitted rather firmly to the inner periphery of the stepped part 9 on the bottom surface of the main body 2, so that it does not move due to the force of water. The mechanism for floating and supporting the container 3 can be achieved by, for example, providing a fitting protrusion on the bottom or inner wall of the main body 2.
It is left to the designer.

In consideration of the possibility that small pieces of the water purifying agent may flow out from the holes in the container bottom plate 3b, a filter net 10 is placed at the bottom of the main body 2 in this embodiment.

The watertight connection between the lid 1 and the main body 2 and the structure in which the water purifying agent can be replaced in the container 3 are arbitrary. In the illustrated embodiment, the lid 1 and the main body 2 are screwed together, but if it is a resin product, they may be joined by fitting. The container 3 is made of resin in which the peripheral wall 3c, the perforated bottom plate 3b, and the legs 7 are also integrally molded, and only the ceiling 3a is made as a separate part, and the ceiling is fitted into the upper edge of the peripheral wall 3c. When the inflow water force is weakened, water falls onto this ceiling 3a, but a peripheral raised portion 11 is provided to prevent the water from flowing down from the ceiling 3a to a diversion channel D passing directly on the outer periphery. The height of this raised portion 11 not only determines the amount of water that can accumulate on the ceiling 3a, but also determines the amount of water that can accumulate on the ceiling 3a.
It also serves as the height of the partition that determines whether the water flow blown around the entire circumference from the gap 12 between the lids 1 enters the detour channel D or accumulates on the container ceiling 3a.

Figures 3 and 4 show an example in which a rotating shaft 13a for a water turbine is set up in the center of the dish-shaped weir plate 6 shown in Fig. 1, and a water turbine 13 is loosely connected to this.A pin 14 is used to prevent the water turbine 13 from escaping. ing. The water wheel 13 is rotated by the water flow that enters from the inlet 4 and is rotated by the water flow that comes out radially from the gap 12, and has the function of making the amount of water that comes out radially from the gap 12 uniform over the entire circumference. Even if water from a faucet or the like flows in one direction or the other, it is rotated by the rotation of the water wheel 13 and flows towards the gap 12, so that it is radiated uniformly. It should be noted that instead of the rotating water wheel 13, simply molding blades that create a swirl on the surface of the dish-shaped weir plate 6 is effective to some extent.

Uniform gap 12 between the periphery of the dish-shaped weir plate 6 and the lid 1
is important as a water outlet. As in the embodiment shown in the figure, if the tube wall of the inlet 4 of the lid 1 is extended slightly downward into a cylindrical shape, and a radial gap 12 is formed between the tip and the upper edge of the periphery of the weir plate 6, the blown water can be removed from the lid. 1, it is advantageous when dropping the entire amount onto the container ceiling 3a. The size of the gap 12 is such that, for example, when the valve of a faucet is fully opened, the water radiated in all directions directly collides with the inner surface of the lid 1 without touching the peripheral raised part 11 of the weir plate, causing the water to flow into the diversion channel D. Make it as large as possible so that it fits inside.

If the gap 12 is small, when the water force is weakened and the water is passed through the water purifying agent container 3, the amount of water will be small and the efficiency will be poor.

The dimensions of the above example are that the inner circumference of the lid 1 and the main body 2 is 57 mm.
mm, outer diameter of water purifying agent container 3 50 mm, inner diameter of inlet 4
12mm, and the height difference between the upper edge of the weir plate 6 and the ceiling peripheral raised part 11 is 3mm, and the gap 12 is 1mm but 2mm.
However, there was no problem and I decided to use 2mm as the actual dimension.

In addition, when the water purifying agent C is colored with ink or the like in an experiment, the water flowing out through the container 3 is colored.

Although the embodiments have been described above, this invention can be varied and applied in various ways depending on the well-known technology of the person who implements it, without changing its gist. Naturally, the shape of the uniform gap component between the weir plate and the inner surface of the lid is designed differently.

(Effects of the invention) This invention leaves the faucet, etc., at the drinking water outlet.
We have created the smallest and simplest water purifier that can be used only when needed.

In other words, we have fundamentally changed the structure of conventional water purifiers, which had a switching valve and two pipes, one through the water purifying agent container and the other through the water purifying agent container, to achieve the same effect by adjusting the water force. .

A water purifying agent container, which cannot be made smaller due to performance reasons, is placed in the center, and is wrapped in a lid with an inlet and an outlet in the center, and a bowl-shaped body, creating a circulation channel that runs directly through the entire volume of the gap along the outer periphery of the container. , compacted into the smallest size.

The water flow that hits the ceiling of the container from the inlet is radially blown out from the uniform gap between the periphery of the dish-shaped weir plate and the lid, so that by adjusting the water force, it can flow directly into the diversion channel or into the ceiling of the container. You can now choose to use or not use the water purification effect by dropping it.

To replace the water purifier, simply remove the lower body from the lid, take out the water purifier container, and replace it as usual.

In other words, this idea is a small and simple water purifier.
Although it is simple, it has excellent practical performance.
