Problems solved by technology

In order to realize the miniaturization of the water purification box, for example, when the cross-sectional area of ​​the water passage in the box is reduced, the deviation of the water flow becomes more significant than when the cross-sectional area of ​​the passage is large, and there is a problem that the burden is only concentrated on the filter element. certain part of the possibility
[0022] In addition, in the shaped activated carbon disclosed in Patent Document 4, the adsorption performance tends to decrease due to the presence of a binder, and if the adsorption performance is to be maintained, the volume of the shaped activated carbon increases and the water purification box becomes larger. question
[0023] Also, if the amount of binder in the shaped activated carbon is reduced in order to prevent a decrease in the adsorption performance, there is a possibility that the shape of the shaped activated carbon will change, etc., and the ease of handling will decrease.
Moreover, especially when reducing the amount of the binder, the shaped activated carbon may swell when it is wet. At this time, the shaped activated carbon pushes the case body and the lid closing the opening of the case body, and there is a burden on the case body and the lid body. possibility of

Embodiment

[0288] Next, refer to Figure 9 , an example of the activated carbon 56 as the molded activated carbon described in the second embodiment will be described.

[0289] Figure 9 , showing the graphs of the first example, the second example, the first comparative example and the second comparative example of the shaped activated carbon when the vertical axis is the removal rate (%) and the horizontal axis is the water flow rate (L). The respective conditions of the first example, the second example, the first comparative example, and the second comparative example are shown in the table below. In addition, the removal rate refers to the value obtained by obtaining the chlorine content on the inlet side of the water purification box 4 and the chlorine content on the outlet side of the water purification box 4, and multiplying (inlet side-exit side) / inlet side×100(%) . In addition, the amount of passing water refers to an integrated value of the amount of water passing through s...

no. 1 Embodiment

[0292] In the first embodiment, the ratio (%) of fibrous activated carbon: granular activated carbon: binder is set to 90:5:5 respectively, and the density after filling (hereinafter referred to simply as packing density) is set to 0.22g / ml, at this time, the water flow rate from the start of water flow until the removal rate, which is the normal exchange target, drops to 80% is 800 (L). In the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.

[0293] Next, in the 2nd embodiment, the proportioning (%) of fibrous activated carbon: granular activated carbon: binding agent is set to 95:0:5 respectively, and the packing density is set to 0.20g / ml. The amount of water passing until the removal rate of the normal exchange target falls to 80% is 800 (L). Similar to the first embodiment, this is equivalent to the amount of water that can be used for about 2.5 months in the case of general household use.

no. 3 Embodiment

[0304] In the 3rd embodiment, the proportioning (mass %) of powdered activated carbon: binder is set to 99:1 respectively, and the average particle diameter of activated carbon is set to 100 μ m. The amount of water passed until the removal rate of derivative methane (THM) (in other words, the adsorption rate) is as low as 80% is 800 (L). In the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.

[0305]Next, in the 4th embodiment, the proportioning (mass %) of powdered activated carbon: binder is set to 98:2 respectively, and the average particle diameter of activated carbon is set to 60 μ m. The amount of water passed until the removal rate of the derived methane of the exchange target was as low as 80% was 850 (L). In the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.

Abstract

Provided is a water purifier comprising a raw water receiving port, a body having a switching mechanism for switching the passage of raw water introduced from the raw water receiving port, and a water purifying cartridge containing a filter material for filtering the raw water and disposed removably relative to the body. The water purifier is characterized in that a male connector is disposed in one of the water purifying cartridge and the body whereas a female connector is disposed in the other and inserted and fitted on the male connector, in that plural pairs of those male and female connectors exist between the body and the water purifying cartridge and along the longitudinal direction of the water purifying cartridge, in that the male connector and the female connector of at least one of the plural pairs form a water passage between the body and the water purifying cartridge, and in that the water purifying cartridge is mounted in the body by fitting the male connector and the female connector.
