Abstract

PURPOSE:To obtain the titled purifier at low cost and to request the time to exchange a cartridge by providing a window at a site from which the cartridge or an outer-shell cartridge can be seen. CONSTITUTION:A freely-detachable cartridge 10 for purifying water consisting of activated carbon 8 and a filter 9 is provided on the downstream side of a washing water hole 5. The cartridge 10 is covered with an outer shell 31 and fixed. The outer shell 31 is fixed through an annular band 32 to a body 3 having a window 33 at a position where the filter 9 part of the cartridge 10 can be seen from the outside. The annular band 32 is allowed to cover the window 33. By using the transparent annular band 32, the contamination of the most contaminated part of the filter 9 of the cartridge 10 can be discriminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a water purifier, and particularly to a water purifier having a removable water purification cartridge.

[Background of the invention]

BACKGROUND ART Conventionally, water purifiers used by being attached to a household water supply have a water purification cartridge made of an attachable activated carbon, a filter, etc., and are replaced when the water purification function deteriorates. For this reason, the entire outer shell that covers the cartridge is made transparent to facilitate determination based on the degree of dirt on the filter. However, if the dirty part of the filter is housed inside the body, it is difficult to determine and it may take a long time. If left for a long period of time, there is a risk of algae growth, which leads to problems such as poor productivity of the outer shell and high price.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a water purifier that is less expensive, has a simple structure, and can facilitate the replacement of cartridges.

[Summary of the invention]

The present invention provides a removable activated carbon that is watertightly attached to the body.
In a water purifier that has a water purification cartridge made of a treatment agent such as a filter, and an outer shell that covers the cartridge is attached to the body, a window is provided in a part of the cartridge or the outer shell where the filter can be seen. This is a unique water source.

According to the present invention, it is possible to provide a water purifier that is inexpensive, has a simple structure, and can prompt the replacement of cartridges.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail below based on the drawings.

The body 3, which has a connection part 2 that can be directly connected to the faucet 1, has approximately cross-shaped water passages, each of which is a raw water inlet hole 4, a purified water inlet hole 5, a raw water outlet hole 6, and a spool insertion hole 7. . A removable water purification cartridge 10 consisting of activated carbon 8, a filter 9, etc. is provided downstream of the water purification inlet hole 5, and an outer shell 31 covering and fixing the cartridge 10 is fixed thereto.

The spool insertion hole 7 has a spool sleeve 13 having a space 12 for communicating the raw water inlet hole 4 and the raw water outlet hole 6.
is inserted through the O-ring 14. Further, a spool 20 is inserted, to which an O-ring 17 for water-sealing the end face of the spool sleeve 13 and the vicinity of the end face of the purified water inlet hole 5 and an O-ring 19 for preventing water leakage toward the dial 18 side for operating the spool 20 are fixed. . 0 ring 1
9. A switching valve 30 is constituted by the spool 20 and the like. The spool 20 moves according to the customer's selection and switches between raw water and purified water, and raw water and purified water are obtained respectively. In other words, when the dial 18 is set to the raw water, the O-ring 17 of the spool 20 will seal the vicinity of the end face of the purified water inlet hole 5, and the water flowing in from the raw water inlet hole 4 will pass through the small diameter part of the 7 spool 20 to the raw water. It passes through the outflow hole 6 and flows out from the raw water outlet 11. Similarly, when the vicinity of the end face of the spool sleeve 13 is water-sealed, water flowing in from the raw water inlet hole 5 enters the spool passageway 29, which has a small diameter or a star-shaped area.
After that, it passes through the water purification inlet hole 5 and reaches the cartridge 10 which is fixed to the body 3 so that it can be attached freely, and the activated carbon 8 filter 9 in the cartridge 10 absorbs the chlorine odor in the tap water and the turbidity generated from the pipes, etc., making it colorless. The water becomes odorless and delicious, and the purified water flows out from the outlet 28.

In order to fix the cartridge 10, the outer shell 31 that covers it has a window 33 at a position where the filter 9 of the cartridge 1o can be seen from the outside through a ring-shaped band 32.
It is fixed to the body 3 having a. A ring-shaped band 32 is used to cover the window 33. Therefore, by making the ring-shaped band 32 transparent, the cartridge 1
The conspicuous dirt on the filter 9 can be identified, and it is possible to easily determine when it is time to replace the cartridge 1o. In addition, the size of the window 33 is kept to a size that can be identified to prevent direct sunlight from irradiating the cartridge 1o.
It suppresses the growth of algae inside. Furthermore, in order to prevent the growth of algae, a part of the ring-shaped band 32 is made transparent and the other part is colored, and the window 33 of the body 3 and the ring-shaped band 3 are made only when checking.
After aligning the transparent parts 2 and checking, it is possible to rotate the ring-shaped band 32 to block direct sunlight.

In particular, if the parts other than the transparent part are white, it can be compared with the degree of dirt on the filter 9 and can be identified more clearly.Since the transparent part is composed of a ring-shaped band 32, it is easy to manufacture and can achieve high transparency. It has great practical effects, such as the ability to

〔Effect of the invention〕

According to the present invention, it is possible to provide a water purifier that is inexpensive, has a simple structure, and can encourage cartridge replacement.
