  The faucet direct-coupled water purifier cartridge itself having such an exchange display is also an embodiment of the present invention.

  Hereinafter, another embodiment will be described.

  In the conventional water purifier, no consideration is given to the fact that the amount of water used varies depending on the family structure of the water purifier user. For example, if it is assumed that the displayed cartridge replacement time is for clean water use by a family of four, in the case of a family of three, the amount of clean water used per day is low, so the cartridge has not reached the end of its life, The cartridge is replaced even though it can perform sufficiently. On the other hand, in the case of a family of five, there is a problem that the amount of purified water used per day is large and the cartridge has already reached the end of its life and has not been replaced even though the cartridge cannot exhibit sufficient performance.

  On the other hand, there are water purifiers that display the cartridge replacement time according to the family structure in the catalog, but it is troublesome for the user to bother to check the replacement time corresponding to his / her family structure in the catalog. Since it may not be noticed that it is displayed in the catalog, it is not an effective means.

  Therefore, in order to solve the above problem, as shown in FIG. 12, by using a plurality of alignment marks 29, it is possible to display cartridge replacement times corresponding to a plurality of family members. FIG. 12 shows three family members, four family members, and five family members in order from the top of FIG. 12. The cartridge replacement time corresponding to the family structure of a family or a family of five can be displayed.

  By using a plurality of alignment marks 29, it is possible to use one alignment mark for instructing the start time of the cartridge and another alignment mark for instructing the replacement time of the cartridge. However, as shown in FIG. If the alignment mark 29 indicates only the replacement time of the cartridge, it is difficult to make a mistake in viewing the display time.

  In FIG. 12, regarding the display of the replacement time, “1... 2 (Omitted)... When a plurality of alignment marks 29 are used, each of the plurality of alignment marks 29 may not necessarily indicate a number representing the month. Therefore, it is preferable to display the replacement time in a short period such as 10 days.

  FIG. 12 shows a state in which “a family of 3 →”, “a family of 4 → January”, and “a family of 5 →” are indicated. As shown in FIG. 12, the plurality of alignment marks 29 are displayed with characters such as “family of 5”, “5 people”, etc. in addition to marks indicating the family structure, so that the cartridge replacement time according to the family structure can be indicated. Can be displayed. The mark indicating the family structure may be anything as long as it can represent a number such as a circle, a triangle, a quadrangle, a star, etc. in addition to the mark that looks like a person as shown in FIG.

  In addition, the replacement time of the cartridge according to the purpose of use is displayed by using multiple characters or marks such as “drinking”, “cooking”, “washing”, and “drinking + washing” instead of the family structure. Cartridge replacement time according to the amount of water used, using multiple counters that are directly distinguished by the guideline of the amount of water used per day, such as “5 L / day”, “10 L / day”, “20 L / day”, etc. Can also be displayed.

  Further, as shown in FIG. 13, the auxiliary alignment mark 30 may be displayed in the vicinity of the plurality of alignment marks 29. If the auxiliary alignment mark 30 is arranged in the vicinity of the plurality of alignment marks 29, the upper, lower, left, right diagonal upper, right diagonal lower, left diagonal upper, left, as shown in FIG. It can be anywhere diagonally below. The distance between the plurality of alignment marks 29 and the auxiliary alignment marks 30 is preferably 10 mm or less, and more preferably within 3 mm, because the plurality of alignment marks 29 corresponding to the replacement time becomes difficult to understand.

  The shape of the assisting mark 30 is triangular so that it can be easily matched with the replacement time. Arrows, circles, “−”, squares, lead lines, etc. may be used.

If the size of the plurality of alignment marks 29 and auxiliary alignment marks 30 is too small, it will be difficult to confirm, and if it is too large, it will be difficult to identify where to indicate, so 50 to 150% of the characters indicating the replacement time of the cartridge 4 It is preferable that it is the magnitude | size of.
About the display method of the auxiliary | assistant alignment mark 30, although you may provide unevenness in the outer wall of the water purifier main body 2, if it displays with a color different from the outer wall of a water purifier using a seal | sticker, printing, etc., it will become easy to confirm and is preferable. . It is more preferable that the assisting mark 30 is displayed in a color different from that of the outer wall of the water purifier main body 2 by using printing on the outer wall of the water purifier main body 2 with unevenness because it becomes easier to confirm. Further, it is preferable that the plurality of alignment marks 29 be easily confirmed if the color is changed for each item.

  Although this invention can be used not only for a faucet direct connection type water purifier but a stationary type water purifier and an undersink type water purifier, the utilization range of this invention is not limited to these.
