Problems solved by technology

[0019] 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

[0284] Next, refer to Picture 9 An example of the activated carbon 56 as the shaped activated carbon described in the second embodiment will be described.

[0285] Picture 9 , The graphs showing the first example, the second example, the first comparative example, and the second comparative example of the molded activated carbon when the vertical axis is the removal rate (%) and the horizontal axis is the water flow (L). The 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 calculating the chlorine content on the inlet side of the water purification cartridge 4 and the chlorine content on the outlet side of the water purification cartridge 4, and dividing (inlet side-outlet side) / inlet side × 100 (%) . In addition, the amount of water passing refers to the cumulative value of the amount of water passing through the use...

no. 1 Embodiment

[0288] In the first example, the ratio (%) of fibrous activated carbon: granular activated carbon: binder was set to 90:5:5, and the density after filling (hereinafter referred to as the filling density) was set to 0.22g / ml, at this time, the water flow rate from the start of water flow until the removal rate as a normal exchange target 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.

[0289] Next, in the second embodiment, the ratio (%) of fibrous activated carbon: granular activated carbon: binder is set to 95:0:5, and the packing density is set to 0.20g / ml. The water flow rate until the removal rate of water as a normal exchange target is as low as 80% is 800 (L). Similar to the first embodiment, in the case of general household use, this is equivalent to the amount of water that can be used for about 2.5 months.

no. 3 Embodiment

[0300] In the third embodiment, the ratio (mass%) of powdered activated carbon: binder was set to 99:1, and the average particle size of activated carbon was set to 100μm. At this time, from the beginning of water flow to the normal exchange target The removal rate of derivatized methane (THM) (in other words, the adsorption rate) is as low as 80% and the water flow rate 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.

[0301] Next, in the fourth embodiment, the ratio (mass%) of powdered activated carbon: binder was set to 98:2, and the average particle size of the activated carbon was set to 60μm. At this time, from the beginning of water flow to normal The water flow rate until the removal rate of the exchange target derived methane is as low as 80% is 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.

Description

technical field [0001] The invention relates to a water purification box and a small water purifier, in particular to a water purifier of this type installed on a faucet of a domestic waterway and a water purification box used for the water purifier. [0002] This application is related to Japanese Patent Application No. 2007-162930 filed on June 20, 2007, Japanese Patent Application No. 2007-169052 filed on June 27, 2007, Japanese Patent Application No. 2007 filed on July 27, 2007 Priority is claimed in Japanese Patent Application No. 196024 and Japanese Patent Application No. 2007-228777 filed on September 4, 2007, the contents of which are incorporated herein by reference. Background technique [0003] Conventionally, what is called a faucet direct connection type water purifier directly attached to a faucet is known. In such a water purifier, there is known a structure in which a bayonet mechanism is provided in order to combine the water purification box containing the...
