Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a water purifier, and more particularly to a water purifier attached to a tap of a water supply.

(Prior Art) An example of a conventional water purifier will be described with reference to FIG.

The water purifier body 31 is attached to the tip of the faucet C of the water supply by the connecting portion 32, and takes in tap water from the water inlet pipe 33 connected to the connecting portion 32. A first filter case 34, in which activated carbon is sealed as a filter material, and a second filter case 35, in which hollow fiber membranes are bundled as a filter material, are housed in the main body portion 31 in close contact with each other. .

36 is a lid that seals the inside of the main body 31, and 37 is a water discharge pipe that is connected to the lid 36 and discharges the purified water filtered by the first and second filters 34 and 35.

As a result, the tap water taken in from the water inlet pipe 33 is
The remaining chlorine or the like is adsorbed by the filter 34, and further the bacteria or the like is removed by the second filter 35.

In this way, when purifying tap water for drinking, it is common practice to remove chlorine, bacteria, etc. contained in the water.To remove chlorine, activated carbon and bacteria must be removed. It is necessary to change the filter material depending on the object to be removed such as a hollow fiber membrane. Therefore, the water purifier includes a plurality of filter cases as in the conventional example.

(Problems to be Solved by the Invention) However, the conventional water purifier has the following problems.

Since a plurality of filter cases are arranged in series and built in, the shape of the main body becomes large, and in the state of being attached to the faucet, the position of the water discharge pipe is separated from the faucet by the length of the main body, which is difficult to use. Also, in the connection part that connects with the faucet,
Although the weight of the water and the weight of the water purifier body are added, since the body of the water purifier has a shape that extends in the lateral direction, the moment due to the weight is large and it is possible to maintain a uniform seal between the connection part and the faucet. Difficult and prone to water leaks. In addition, since water always passes through multiple filter cases, the filter material deteriorates quickly, and because multiple filter cases with built-in filter materials are arranged in series inside the main unit, it is difficult to replace them individually. There is a problem that exists.

Therefore, the present invention has been made to solve the above problems, and an object thereof is to provide a water purifier that is easy to use and does not cause water leakage.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, in a water purifier attached to a tap of a tap, two filter cases having filter materials housed therein and having substantially equal weights, and a main body for holding the two filter cases horizontally at a target position with the tap interposed therebetween. And a section.

Further, the main body portion is connected to the connection portion that connects the main body portion and the faucet, the discharge port that discharges the water taken in from the connection portion to the outside, and the connection portion that communicates with the first flow path. A switching valve for switching water from the connecting portion to either one of a second flow passage communicating with the two filter cases or a third flow passage communicating with the discharge port; and the two filter cases. It may be configured with a fourth flow path communicating with the discharge port.

(Function) Since the filter cases of substantially equal weight containing the filter material are horizontally arranged at symmetrical positions with the faucet interposed therebetween, the force applied to the connecting portion connected to the faucet becomes substantially uniform. In addition, by the switching valve, the water supplied from the faucet to the connection part,
It is possible to switch to either the second flow passage communicating with the filter case or the third flow passage communicating with the discharge port, and it is possible to select whether or not to purify water.

The first filter case 7 and the second filter case Since 8 has substantially the same shape and is formed to have substantially the same weight,
Even when water is passed through the both filter cases 7 and 8, the force applied to the sealing material 25 that abuts on the tip portion of the faucet C is substantially uniform.

Further, the inside of the main body 1 is connected to the connecting portion 2 through the first flow path 26, and the water from the connecting portion 2 is supplied to the two filter cases 7,
A switching valve 3 for switching to either one of a second flow passage 5 communicating with 8 and a third flow passage 6 communicating with the first discharge port 23.
And a fourth flow path 17 that connects the second filter case 8 and the second discharge port 18 is provided. The second flow path 5 is connected to the flow path 11 that connects the switching valve 3 and the first filter case 7 with the first flow path 11.
The filter case 7 and the flow path 14 that connects the second filter case to each other. The second ejection port 18 is provided at a substantially central portion of the first ejection port 23.

In addition, the first type in which the cartridge filters 9 and 10 are housed

After attaching the water purifier to the faucet C using the screw provided in the connecting portion 2, first, the handle 4 is operated to move the internal switching valve 3 to move the first flow path 26 and the second flow path 5. And communicate with. As a result, the water supplied from the faucet C passes through the connecting portion 2, the first flow passage 26, and the flow passage 11 in the second flow passage 5 and the first opening portion of the first filter case 7. It flows from 12 into the first filter case 7. First filter case 7
Inside, water moves upward along the inner peripheral surface of the first filter case 7 as shown in FIG. 3, and is supplied to the upper end of the first filter 9 housed in the first filter case 7. To be done. The water from which residual chlorine and the like have been adsorbed and removed when communicating with the first filter 9 is again fed through the second opening 13 of the first filter case 7 provided below the first filter 9 to the first opening 13. It flows out to the flow path 14 in the second flow path 5 that connects the filter case 7 and the second filter case. Before and after the first filter 9, prefilters 19 and 20 for removing relatively large foreign matters such as iron rust may be provided as shown in FIG.

Further, the water supplied to the second filter case 8 via the flow path 14 flows into the second filter case 8 through the third opening 15 as in the case of the first filter case 7 Moving upward along the inner peripheral surface of the filter case 8 of the second
Is supplied to the upper end of the filter 10. Bacteria and minute dust are removed by the second filter 10, flow out from the fourth opening 16 to the fourth flow path 17, and are discharged from the second discharge port 18 to the outside.

On the other hand, the handle 4 is operated to move the internal switching valve 3 to connect the first flow path 26 and the third flow path 6 to each other. In this case, the water supplied from the faucet C is connected to the connecting portion 2 and the first flow path 2

In addition, a porous filter material 24 is attached to the inside of the lid 27 to remove foreign matter in the water, improve the water flow to the entire lid 27, and uniformly discharge water from the small holes. Is also good.

With this configuration, if you get water for drinking,
Water with high water pressure can be obtained by passing through one filter case, purifying and discharging, and when using for hand washing, dishwashing, etc. other than drinking, directly discharging without passing through the filter case. Further, since the two types of filter materials are divided into two filter cases and each filter case is independently attached to and detached from the main body portion, the filter material can be easily replaced.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments,
Of course, many modifications can be made without departing from the spirit of the invention.

(Effect of the Invention) When the water purifier according to the present invention is used, since the filter cases having substantially the same weight and containing the filter material are horizontally arranged symmetrically across the faucet, the position of the discharge port is defined as the faucet. The positions can be substantially the same, and the force applied to the faucet becomes substantially uniform, so that water leakage between the connecting portion and the faucet can be prevented. Further, if different filter materials are stored in the two filter cases, individual replacement of the filter material becomes easy.

In addition, the switching valve can switch the water supplied from the faucet to the second flow path communicating with the filter case or the third flow path communicating with the discharge port. Purified water can be obtained with high water pressure when washing dishes and the like. Further, along with this, the water from the faucet is not always passed through the filter case, and the life of the filter material is extended, which is a remarkable effect.
