Moreover, the front-end | tip of this water supply hose 20 and the water discharge hose 21 is connected with the switching cock 23 with which the water faucet which is not shown in figure was mounted | worn. And the flow path of water can be switched by operating the lever 23a with which the switching cock 23 was equipped, discharging raw water supplied from a water tap, or supplying it in the water purifier 11 as it is. It has become.
[0013]
As shown in FIG. 1, filter media 24 are stacked and accommodated in the water purifier main body 14 in a predetermined order. Each of these filter media 24 has a function of purifying raw water into purified water, that is, a function of removing impurities in the raw water, or a function of imparting functionality to the raw water by adding various components. And the raw | natural water supplied in the water purifier main body 14 through the water supply opening | mouth 18 is contacted in order from the filter medium 24 in the upper direction, descend | falls in the water purifier main body 14, and is purified.
[0014]
A partition plate 25 is interposed between the filter media 24 to partition the filter media 24. Further, a bottom plate 26 and a mesh flange 27 are accommodated in order from the end side so as to sandwich the filter media 24 formed in layers on the upper and lower portions in the water purifier main body 14. The mesh flange 27 has a disk shape, and is sandwiched and fixed between the end of the water purifier main body 14 and the upper lid 15 or the lower lid 16 at the outer peripheral edge thereof.
[0015]
Each said filter medium 24 is comprised by 1 type or multiple types chosen, for example from activated carbon, a nonwoven fabric, ceramics, a natural stone, a medicinal stone, coral, etc. And it can function as what is called a water purifier by combining these filter media 24 arbitrarily and laminating in a predetermined order.
