Embodiment 1）

[0179] Coconut shell activated carbon is used as a powder filter material. The particle diameter D50 when the cumulative value based on the particle size distribution of the volume becomes 50% is 197 μm, the particle diameter D90 when the cumulative value based on the particle size distribution of the volume becomes 90% is 295 μm, and the cumulative value based on the particle size distribution of the volume becomes 10% The particle size D10 is 141 μm. fill the activated carbon with image 3 In the filter cartridge of the structure, measure to show the pressure loss value (1) when the flow rate is 3.5L / min. Then, measure the pressure loss value (2) of the filter cartridge after removing the powder filter material, subtract the pressure loss value (2) from the pressure loss value (1), and calculate the pressure loss value of the powder filter material part (3 ). As a result, the pressure loss in the powder filter section becomes very small.

Embodiment 2）

[0181] In addition to the particle size D50 of 211 μm when the cumulative value based on the particle size distribution of the volume is 50%, the particle diameter D90 of 319 μm when the cumulative value of the volume based on the particle size distribution is 90%, and the particle size based on the volume The pressure loss was measured in the same manner as in Example 1, except for the coconut shell activated carbon whose particle size D10 was 143 μm when the cumulative value of the distribution was 10%. The pressure loss was higher than in Example 1, but there was no practical problem.

reference example 1）

[0183] In addition to the particle size D50 of 199 μm when the cumulative value based on the particle size distribution of the volume is 199 μm, the particle size D90 of 319 μm when the cumulative value of the volume based on the particle size distribution is 90%, and the particle size based on the volume. The pressure loss was measured in the same manner as in Example 1, except for the coconut shell activated carbon whose particle size D10 was 116 μm when the cumulative value of the distribution was 10%. The pressure loss is higher than 0.018MPa.

[0184] The conditions of the powder filter materials of Examples 1, 2 and Reference Example 1 are summarized in Table 1, and the pressure loss values ​​are summarized in Table 2. There is no practical problem if the pressure loss value (3) at the time of passing water at 3.5 L / min in the powder filter part is 0.018 MPa or less.

Abstract

Provided is a water purifier filter cartridge comprising: a cylindrical filter body; and a cylindrical powdered-filter-material module accommodating a powdered filter material and a cylindrical hollow-fiber-membrane module accommodating a hollow fiber membrane, the modules being accommodated coaxially within the filter body. One end of the hollow-fiber-membrane module is connected in a liquid-tight manner to a purified water discharge port, and the other end is connected in a liquid-tight manner, either directly or via another member, to a top inner lid of the powdered-filter-material module.The powdered filter material satisfies 0.5<=(D90-D10)/D50<=0.9 where, when aligning the particles in particle size order, D90 is a particle size the integrated number of which is 90%, D10 is a particle size the integrated number of which is 10%, and D50 is a particle size the integrated number of which is 50%.

Description

technical field [0001] The present invention relates to a water purifier for purifying tap water, a bracket for holding the water purifier, and a filter cartridge used in the water purifier. Background technique [0002] In the past, as a water purifier for purifying tap water, there are known a faucet direct connection type water purifier directly connected to the spout of a water tap, a fixed type water purifier placed on a cabinet (kitchen) and used, and a placed water purifier. Under-the-sink type (or built-in type) water purifiers used for the interior of cabinets, etc. Since the total amount of filtered water that can be treated by the filter material filled in the filter cartridge for the water purifier is limited, the user continues to use the water purifier while regularly replacing the filter cartridge for the water purifier. [0003] Under-the-sink water purifiers are larger than direct-connected water purifiers or fixed-type water purifiers, and can handle a lar...
