Description

[0001]
[Industrial application fields]
The present invention relates to a domestic water softener that softens raw water with an ion exchange resin.
[0002]
[Prior art]
In recent years, water softeners that soften raw water with ion exchange resins have been widely used in homes. Below, the conventional domestic water softener is demonstrated.
[0003]
FIG. 5 is a structural view of a conventional domestic water softener, and FIG. 6 is a transverse sectional view thereof. In FIG. 5, the raw water sent from the water supply side passes through the water purification cartridge 1, enters the water channel switching valve 2, and is distributed to the two cartridges 3 with built-in ion exchange resin. The water that has passed through one of the ion exchange resin built-in cartridges 3 again enters the water channel switching valve 2 and is discharged from the water discharge pipe 4, and the water that has passed through the other ion exchange resin internal cartridge 3 also enters the water channel switching valve 2 and drains again. Is done. At this time, one ion exchange resin built-in cartridge 3 functions to change hard water to soft water, and the other ion exchange resin built-in cartridge 3 regenerates the ion exchange resin.
[0004]
FIG. 6 shows the arrangement of a water purification cartridge 1, two ion exchange resin built-in cartridges 3 and a substrate box 5. As shown in the drawing, the cross-sectional shape of the ion exchange resin cartridge 3 ensures the strength of water pressure resistance. Because of this, it has a cylindrical shape. 7a is a boss for connecting the main body of the ion exchange resin built-in cartridge 3 and the lid with screws, 7b is the flange, and 8 is for fixing the ion exchange resin built-in cartridge 3 to the frame 9 disposed inside the main body case 6. It is a flange for. Each component described above is housed inside the main body case 6.
[0005]
[Problems to be solved by the invention]
However, in the conventional configuration, since two cylindrical ion exchange resin built-in cartridges 3 are arranged in parallel, the overall lateral dimension W1 becomes large, and there is a problem that it is difficult to install in a kitchen where space is small. It was.
[0006]
Therefore, an object of the present invention is to provide a domestic water softener that can be installed compactly even in a narrow space of a kitchen.
[0007]
[Means for Solving the Problems]
For this reason, the present invention has an ion exchange resin built-in cartridge having a long cross-sectional shape , and the body surface of the cartridge is shifted asymmetrically with respect to the long center line of the cross-sectional shape. A plurality of collar portions for fixing to the case-side frame are formed .
[0008]
[Action]
With the above configuration, the horizontal dimension of the cartridge with built-in ion exchange resin is reduced, and the vertical dimension is increased to a range where there is no structural problem, thereby reducing the overall horizontal dimension when the product is completed. It is possible to install even in a narrow space.
[0009]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a structural view of a domestic water softener according to an embodiment of the present invention, FIG. 2 is a transverse sectional view thereof, FIG. 3 is an exploded perspective view of the same ion exchange resin built-in cartridge, and FIG. In FIG. 1, raw water sent from the water supply side passes through a water purification cartridge 1, enters a water channel switching valve 2, and is distributed to two cartridges 10 with built-in ion exchange resin. Water that has passed through one ion exchange resin built-in cartridge 10 again enters the water channel switching valve 2 and is discharged from the water discharge pipe 4, and water that has passed through the other ion exchange resin built-in cartridge 10 also enters the water channel switching valve 2 and drains again. Is done. At this time, one ion exchange resin built-in cartridge 10 functions to change hard water to soft water, and the other ion exchange resin built-in cartridge 10 regenerates the ion exchange resin. Each of the above components is housed inside the main body case 6.
[0010]
FIG. 2 shows the arrangement of the water purification cartridge 1, the two ion exchange resin built-in cartridges 10, and the substrate box 5. As shown in the drawing, the cross-sectional shape of the ion exchange resin built-in cartridge 10 is a vertically long oval. Or it is elliptical, so even if two of them are arranged side by side, the overall lateral dimension W2 can be made considerably smaller than the conventional lateral dimension W1 shown in FIG. Therefore, it can be made compact as a whole, and is extremely advantageous as a domestic water softener installed in a kitchen in a narrow space.
[0011]
3 and 4, the ion exchange resin built-in cartridge 10 includes a main body 11 and a collar portion 12 that is detachably attached to a lower portion of the main body 11. Four bosses 13 are formed on the lower body surface of the main body 11, and four collar portions 14 corresponding to the bosses 13 are formed on both side surfaces of the long side of the collar portion 12. Accordingly, the collar portion 12 is attached to the main body 11 by screwing the screws 15 into the collar portion 14 and the boss 13.
[0012]
In addition, flanges 16 are formed at the corners on the diagonal of the collar portion 12 so as to be fixed to the main body case 6 side. In FIG. 1, reference numeral 17 denotes a plate-like frame disposed horizontally in the lower part of the main body case 6, and the collar portion 12 is fixed inside the main body case 6 by screwing screws 18 into the flange 16. Is done.
[0013]
As shown in FIG. 2, the collar portion 14 and the flange 16 are provided so as to project asymmetrically with respect to the center line NA. Accordingly, as shown in the drawing, the two left and right ion exchange resin built-in cartridges 10 are reversed left and right so that the respective collar portions 14 are alternately arranged, so that the collar portions 14 do not take up a horizontal space. In addition, the occupation width D occupied by the two cartridges 10 with built-in ion exchange resin can be made as small as possible to achieve compactness.
[0014]
Further, by removing the screw 18 from the flange 16, the main body 11 and the collar portion 12 can be integrally removed from the main body case 6 to perform maintenance and inspection, exchange of the ion exchange resin built-in cartridge 10, or the like.
[0015]
【The invention's effect】
As described above, according to the present invention, since the cross-sectional shape of the cartridge with built-in ion exchange resin is elongated, the overall lateral dimension of the home water softener is reduced, and the size in the vertical direction is not structurally problematic. By enlarging the range, the overall horizontal dimension when the product is completed can be reduced, and it can be easily installed in a narrow space kitchen.
[0016]
In addition, by forming a collar part on the body surface of the cartridge with a built-in ion exchange resin so that the collar part is fixed to the body case side by shifting the position with respect to the center line, the collar part does not take up a lateral space. The occupied width when multiple cartridges with ion exchange resin are arranged side by side can be reduced as much as possible, and the cartridges can be made more compact. Thus, these ion exchange resin built-in cartridges can be molded with the same mold, and the cost can be reduced.
