In order to extend the replacement period and achieve the above objectives, efforts are being made to improve performance, but on the other hand, the problem of common bacteria has been brought into focus. In other words, by improving the performance, the water that accumulates in the activated carbon layer of the treatment material and the water purification outlet becomes completely chlorine-free water, and the bacteria that invaded from the water purification outlet cause the breeding of general bacteria there, resulting in poor water quality. Standards may also be included. It becomes more noticeable when the cartridge is left unused after being used for a long time, and depending on the structure, it can be several hundred times higher than the water quality standard. Providing water purifiers that are more hygienic and safer than water purifiers.

A treatment agent such as activated carbon 8. reaches the water purification chamber 10a at both speeds and is stored in the water purification chamber 10a. The filter 9 absorbs chlorine odor, trihalomethane, and turbidity generated from pipes, etc. in the tap water, resulting in colorless, odorless, and delicious water.
It flows out from the purified water outlet 19. Further, a part of the raw water similarly passes through the purified water inlet hole 5, then passes through the bypass passage 100, and flows out from the purified water outlet. That is, from the water purification outlet, the purified water passes through the water purification chamber 10a, and the purified water and the raw water that has passed through the bypass passage 100 are mixed together and flow out.

With the above configuration, it is possible to extend the replacement period when replacing the water purification cartridge to ensure its functionality, and to improve performance in order to adsorb more chlorine, trihalomethane, and turbidity. In other words, this is caused by the above-mentioned improvement in performance. Even if the water accumulated in the activated carbon layer of the treatment agent and the water purification outlet 19 becomes completely chlorine-free water, when you switch the dial to purified water and draw purified water for drinking, it is necessary to remove only a certain amount of chlorine. This resulted in the tap water containing the bacteria, killing the common bacteria that had grown in the stagnant water.

衛生的でかつ、安全で美味な水を供給できるものである
It is possible to supply water that is sanitary, safe, and delicious.

As is clear from the above, 2mg/41 of tap water is 0.
.. The processing amount to reach 4mg/Ω is approximately 6 times,
Customers will have to replace their water purifiers for a longer period of time, and will be able to use water purifiers that can be used with peace of mind at lower running costs.
The effect is enormous.

Therefore, when switching from using raw water to purified water, or from purified water to raw water, raw water will flow out from the purified water outlet during the process. That is, in the process of purifying water, raw water containing chlorine initially flows out from the purified water outlet, and even in the process of combining with raw water, raw water containing chlorine flows out from the purified water outlet.

In order to obtain the same effect, as shown in Fig. 9, a valve part (■) may be provided in a part of the bypass passage 100. The ball 103, which is equivalent to water, passes through the valve part (2) in a floating state, but after the switching is complete, the amount of water increases, the pressure increases, and the valve part (2) becomes in a sealed state.

The raw water that has accumulated at the raw water outlet gradually has chlorine adsorbed by the treatment agent 8 such as activated carbon, becomes chlorine-free, and passes through the purified water outlet 1.
Even if there is a large number of general bacteria in the accumulated water including the activated carbon layer due to general bacteria entering from 9, they cannot be killed because the raw water containing chlorine initially flows out through the bypass passage 100 and from the purified water outlet 19. This makes it possible to obtain a water purifier with higher performance and safety.
