Abstract

PROBLEM TO BE SOLVED: To make obtainable a guide when a cartridge is inserted, to make it possible to align a body with a base when a cartridge is inserted, and further to strengthen a case, by providing a vertical rib in the body and making the cartridge packed with a purifying material in the body freely attachable and detachable. SOLUTION: Three vertical ribs 12 are provided inside a body 11, and a step 22 (rib) in contact with the rib 12 is provided for the cartridge 21 contg. a purifying material. The cartridge 21 is slid with the rib 12 in contact with the step 22 and inserted into the body 11, and a projecting port 23 is engaged with a hole 33 and projecting port 24 with a hole 34. Consequently, the projecting ports 23 and 24 of the cartridge 21 are naturally inserted into the holes 33 and 34 of a base 31. Alignment is established when the cartridges are exchanged, and further the body is remarkably strengthened by the presence of the rib.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier for tap water.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for safety, especially for drinking water, and various water purifiers have been proposed to improve water quality because of this demand. The water purifier is filled with a purifying material, which needs to be replaced periodically. Therefore, the purifying material is generally made into a cartridge.

However, when the cartridge is filled into the case of the water purifier, there are cases where the case is deep, and in this case, it is difficult to align the cartridge with the receiving hole, so that the case is difficult. The current situation is to start over.

Further, when assembling the base and the body constituting the case of the water purifier, it is necessary to use a special jig for positioning the two, which may be troublesome. Further, the case needs to have strength, but for this purpose it is necessary to increase the wall thickness or to form a rib for reinforcement.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can guide the insertion of a cartridge, and can align the cartridge with a base. Is to provide a structure of a water purifier which increases the strength of the case.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the gist of the present invention is that a water purifier case is formed of a body, a base, and a lid. What is claimed is: 1. A water purifier in which a cartridge having a body filled with a purifying material is detachably provided, wherein the body is provided with a vertical rib. It is elongated in the direction of attachment and detachment of the cartridge, and its tip is the final deep portion of the fitting of the base into the body.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The water purifier of the present invention has a long rib formed on the inside of the body. When the cartridge is attached or detached, the cartridge can be attached along the rib. There is a feature that alignment is easy.

When assembling the body and the base, it is realized by pushing the base in which the both are fitted to each other until the base comes into contact with the tip of the rib. Since the rib provided in the longitudinal direction of the body serves as a reinforcing material, the strength is sufficient even when an excessive force is applied.

It is preferable to form a step on the outer side of the cartridge which can be slid by engaging with the rib of the present invention.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the water purifier of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a partially exploded sectional view of the water purifier of the present invention. In the figure, reference numeral 11 denotes a body, on which three ribs 12 are provided in a vertical direction. Numeral 21 denotes a cartridge having a built-in purifying material, preferably having a step (rib) 22 in contact with the above-mentioned rib 12. The cartridge 21 is in contact with the rib 12 and this step 22. Is inserted and attached. Reference numeral 31 denotes a base, and reference numeral 32 denotes an inlet for raw water and an outlet for purified water.
And this 32 ₁ This is the inlet raw water base - have continued to the central portion of the hole 33 of the scan 31, while the hole 34 is intended to take out the purified water, which is followed by water purification outlet 32 _2.

At the center of the tip of the cartridge 21, there is provided a projection 23 for fitting into a hole 33 for introducing raw water, and at the side of the tip, a projection 24 for obtaining purified water. , The cartridge 21 is slid and inserted into the body 11 so that the protrusion 23 and the hole 33 and the protrusion 24 and the hole 34 are fitted.

A cylindrical body 25 is formed in the center of the cartridge 21, and a donut-shaped space 2 around the cylindrical body 25 is formed.
Activated carbon and ceramic granules for purifying raw water are filled in a layered manner. A hole 2 connecting the cylindrical body 25 and the donut-shaped space 26 is provided above the cartridge 21.
7 and 28 are formed, respectively, and the inner lid 29 is fitted therein to connect the holes 27 and 28. 13 is body 1
1 is a lid fitted on the upper side.

In assembling this water purifier, the body 1
The fitting is completed by fitting the base 31 and the base 31 until the base 31 contacts the lower end of the rib 12. On the other hand, when the combination of the body 11 and the cartridge 21 is inserted into the body 11 while the ribs 12 of the body 11 and the step portions 22 of the cartridge 21 are in contact with each other, the protrusions 23 of the cartridge 21 24 naturally fits into the holes 33, 34 of the respective bases 31. Even if the step portion 22 does not exist in the cartridge 21, the protrusion 23 provided in the center portion of the cartridge 21 and the hole 33 in the center of the base 31 are fitted as they are. After that, the cartridge 21
By rotating the left and right, the fitting of the projecting port 24 and the hole 34 can be completed.

[0014] When describing the water purifier of the present invention together with the flow of water, first of all the raw water inlet 32 ₁ from entering the raw water, base - scan 3
1 and reaches the central hole 33, and the cartridge 2
1, the inner cylinder 25, and the central hole 27 of the cartridge 21.
Then, it exits further upward and then enters the interior (space 26) of the cartridge 21 through the upper side hole 28. The tap water is purified by the purification material base from spout 24 - enter the hole 34 of the scan 31, purified water from the purified water outlet 32 ₂ and is supplied.

[0015]

According to the present invention, since the ribs are provided in the body, the center can be aligned when the cartridge is replaced, and the fitting of the body and the base can be aligned when the body and the base are assembled. The body is significantly increased in strength due to the presence of the rib.
