2. Description of the Related Art A simple water purifier using a cartridge is
Various proposals have been made, but the most problematic point is that elution of minerals should be performed in an optimal state without excess or deficiency. Knowing the exact time to replace the cartridge,
If possible, it is also possible that it is hygienic because it handles drinks and that it is a simple type that can fit in the refrigerator.

As a conventional water purifier of this type, there is a so-called electrolytic type alkaline ion water purifier, but it is naturally expensive because it uses electric power to electrolyze water.
You can't simply put it in the refrigerator to cool it.

[0004] Further, the conventional mineral water conditioner elutes minerals and the like by immersing the ceramics or ore in water, but if the immersing time of the ceramics is long, Is excessively eluted, and if it is short, the opposite phenomenon occurs.

Therefore, the present inventors have conducted various studies on how to solve the above items 1 to 3 in a water purifier that also elutes minerals of this type, and as a result, completed the present invention. I did.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the problem to be solved is that this type of water purifier can be used for elution of minerals and is convenient to use. It is to do.

That is, first of all, the object of the invention according to claim 1 is that the cartridge 40 can be easily replaced, and the elution of the mineral content from the cartridge 40 can be performed in an optimal state without excess or deficiency. An object of the present invention is to provide a simple water purifier 100 that can be carried out, is hygienic as a drink, and that can be put in a refrigerator.

The object of the invention according to claim 2 is to achieve the above-mentioned object of claim 1,

[0009]

In order to solve the above problems, first, the means adopted by the invention according to claim 1 will be described with the reference numerals used in the description of the embodiments described later. , "A simple water purifier 100 for generating mineral purified water by passing raw water through a replaceable cartridge 40 and temporarily storing the mineral purified water,
This simple water purifier 100 has a main body 10 having a storage portion 11 at the bottom, an inner container 20 housed in an upper part of the main body 10 and supporting a cartridge 40 at its bottom opening 21 in a replaceable manner, and the inner container 20. 3 for covering the upper opening 22 of the
0, and the volume of the storage portion 11 on the main body 10 side and the volume of the medium container 20 are substantially matched so that the raw water in the medium container 20 entirely falls into the storage portion 11 through the cartridge 40. The surface of the cartridge 40
It is a simple water purifier 100 using the cartridge 40 characterized in that it can be located below the lower surface of the.

That is, the simple water purifier 100 stores the middle container 20 in the upper part of the main body 10 having the storage portion 11,
The cartridge 40 is supported in the bottom opening 21 of the middle container 20, but the raw water is injected directly into the middle container 20 by removing the lid 30 on the middle container 20. . When the raw water in the medium container 20 becomes full, the water injection is naturally stopped and the lid 30 is closed.

The raw water contained in the inner container 20 enters the inside through the water passage hole 41 formed in the upper surface of the cartridge 40 or the knob portion 43 and passes through the activated carbon or ceramics layer therein, but in the meantime. Residual chlorine in raw water is adsorbed by activated carbon, and apart from this, minerals are eluted from ceramics. The purified water containing minerals formed in this way, that is, the mineral purified water, is supplied from the drip hole 42 formed at the bottom of the cartridge 40 to the storage section 11 below.
Within a predetermined time (in the embodiment described later, the storage unit 11
If it is 1 liter, it is added dropwise for a few minutes). That is, the raw water contained in the medium container 20 passes through the cartridge 40 at a constant flow rate, together with the fact that the liquid surface of the cartridge 40, which will be described below, does not come into contact with the ceramics in the cartridge 40. The contact time is kept constant.

When the dripping of the purified water into the storage portion 11 is completed, in the present invention, the volume of the storage portion 11 on the main body 10 side is made substantially equal to the volume of the middle container 20, so that FIG. 1 and FIG. As shown in, the purified water surface is located below the lower surface of the cartridge 40. This allows the cartridge 4
0 is not soaked in purified water at all, and it is natural that the adsorbed substance does not return to the mineral purified water from the activated carbon in the cartridge 40, and an extra mineral content may be eluted from the ceramics in the cartridge 40. There is no.

Of course, the main body 10, the inner container 20, the lid 30, the container of the cartridge 40, etc. may be made of sanitary plastic, and these can be easily removed from each other so that they can be washed. Since it is easy and the lid is covered by the discharge port cap 23 and the lid 30, it is sanitary as a result.

Further, the attachment / detachment of the cartridge 40 to / from the bottom opening 21 of the middle container 20 can be easily carried out only by inserting / removing the cartridge 40 into / from the bottom opening 21 from above. As shown in FIGS. 2 and 5, the cartridge 40 of the embodiment has the knob portion 43 at the upper end, and therefore, by using the knob portion 43, the cartridge 40 can be easily taken in and out.

Further, since the simple water purifier 100 does not have a power cord and has a very "compact" shape, it can be put in the refrigerator as it is, and mineral water can be stored. It can also be cooled easily.

Therefore, the simple water purifier 100 according to claim 1
The cartridge 40 can be easily replaced, and the mineral content can be eluted from the cartridge 40 in an optimum state without excess or deficiency, and it is sanitary for handling drinks, and is in a refrigerator. It is a simple type that can be entered.

In order to solve the above problems, the means adopted by the invention according to claim 2 is the simple water purifier 10 according to claim 1.
No. 0 is “provided with an indicator 50 for displaying the amount of water used on the upper surface of the lid 30”.

That is, the cartridge 4 of claim 2
The simple water purifier 100 using 0 is the cartridge 4
The replacement time of 0 is easily recognized by the display 50, and the cartridge 40 can be replaced without waste according to the display of the display 50.

A display 50 of an embodiment to be described later incorporates a dial 1 (51) and a dial 2 (52) which are rotated by a finger or the like, and values indicated by these dial 1 (51) and dial 2 (52). The display window 54 provided on the cover plate 53
It is made to be visible from. That is, since the lid 30 to which the display device 50 is attached must be washed with water, the display device 50 has a simple structure, that is, a structure that can be washed with water.

Further, the replacement time of the cartridge 40 is mainly determined by the adsorption capacity of activated carbon such as chlorine, or whether or not the elution of minerals from the ceramics is sufficient. Whether or not it depends on the amount of water used. Therefore, this indicator 50 is used for the middle container 20.
The number of times raw water is filled is displayed inside. That is, the user turns the dial 1 (51) indicating the first place of the number so that the number advances by 1 every time the raw water is filled in the medium container 20 (every 1 liter in the present embodiment). Of. The dial 1 (51) is linked with the dial 2 (52) indicating the tenth place or more, so the display of the amount of water used is sequentially added, but the dial 2 (52) has reached the limit of use. At this time, a message such as "it is time to replace" is displayed, and the user replaces the cartridge 40 based on this message.

In other words, since the display 50 displays the actual amount of water used, it is possible to accurately display the replacement time as compared with the conventional general display that displays the number of days of use. Is what you can do. When the cartridge 40 is replaced, when the next replacement time is displayed with a memo or the like, it is difficult to accurately display the replacement time because the amount of water used on the day changes.
Since the display indicates exactly the actual amount of water used, the replacement time of the cartridge 40 can be displayed accurately.

Therefore, the simple water purifier 1 according to claim 2
00 has the same function as that of the simple water purifier 100 according to claim 1, and can know the exact replacement time of the cartridge 40.
