Description

  The present invention relates to a water purifier.

  Conventionally, tap water has been obligated to add chlorine for sterilization, and there is little concern that tap water will be contaminated by various germs, but the taste of water has been impaired due to the odor of chalk. It has also been confirmed that carcinogenic trihalomethanes are produced in tap water by reacting chlorine with organic substances such as humic substances contained in tap water. Furthermore, due to recent pollution of rivers and lakes, etc., it has been confirmed that tap water that uses these as raw water contains mold odor-causing substances as trace components. Therefore, water purifiers are widely used to remove substances that impair the taste of water and harmful substances.

  A general structure of a water purifier includes a cartridge having a granular filter medium layer filled with a granular filter medium such as activated carbon, and a casing in which the cartridge is stored. Such a water purifier includes a water supply pipe through which a fluid to be treated such as tap water that has not undergone water purification is guided, and a water discharge pipe (drainage pipe) that guides the liquid to be treated that has passed through the cartridge and from which harmful substances have been removed to the outside. ) Etc. and used.

  However, in a conventional water purifier, a water supply pipe through which a fluid to be treated such as tap water that has not been subjected to a water purification treatment is guided, or a water discharge pipe that guides the fluid to be treated that has passed through the cartridge and from which harmful substances and the like have been removed to the outside ( When replacing a cartridge that is difficult to work, such as where the connection location is deep, and has lost its purification capacity, it takes time to replace the cartridge. There was a problem that it was difficult to easily replace the cartridge.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a water purifier capable of easily exchanging a cartridge for purifying a fluid to be treated.

  The object of the present invention is a water purifier comprising a cartridge for purifying a fluid to be treated and a casing into which the cartridge is inserted, wherein the casing is open at one end and closed at the other end by a blocking wall. , Formed in a cylindrical shape in which the direction from one end side to the other end side is a longitudinal direction, and the closed wall has a supply pipe connection portion for guiding a fluid to be processed supplied from the outside to the cartridge, and A discharge pipe connecting portion that guides the fluid to be processed purified by the cartridge to the outside is provided, and the cartridge has an introduction portion that fits into the supply pipe connecting portion and can introduce the fluid to be processed into the cartridge And a lead-out part that can be fitted into the discharge pipe connection part and lead out the processed fluid processed inside the cartridge is provided on the side wall of the casing.

It is possible to smoothly remove the cartridge from the casing while suppressing the occurrence of (low pressure state) to the maximum.

  Moreover, it is preferable that the said communication part is a slit extended toward the other end side from the one end side of the said casing. According to such a configuration, as described above, when the cartridge is inserted into the casing, the air in the casing pushed out by the cartridge is guided to the outside of the casing through the slit-like communication portion, When the cartridge set in the cartridge is taken out, the effect of guiding the air outside the casing into the casing is exhibited, and the following effects are also exhibited. That is, by configuring the communication portion in a slit shape, the peripheral wall of the casing is easily bent. As a result, the shape of the inner peripheral portion of the casing is substantially the same as the shape of the outer peripheral portion of the cartridge, and the outer peripheral surface of the cartridge is in sliding contact with the inner peripheral surface of the casing. The cartridge can be inserted by expanding the opening at the one end, and the setting operation of the cartridge to the casing can be facilitated.

  The stopper includes a stopper means for restricting movement of the cartridge relative to the casing in a state where the introduction portion and the supply pipe connection portion, and the lead-out portion and the discharge pipe connection portion are respectively fitted. The means includes a penetrating portion formed on the side wall of the casing, a concave portion formed at a predetermined position on the side wall side of the cartridge corresponding to the penetrating portion, and being inserted into the concave portion via the penetrating portion. It is preferable to include a movement restricting portion in which at least a partial region is interposed in a space portion formed by the concave portion and the penetrating portion. The penetrating portions are respectively formed on opposite side walls of the casing, and the concave portions are respectively formed at predetermined positions on the side walls of the cartridge corresponding to the penetrating portions. And each of the recesses is formed to extend in a direction perpendicular to the insertion direction of the cartridge, and the movement restricting portion includes a pair of insertion pieces respectively inserted into the corresponding through portion and the recess. Preferably it is.

  By providing such a stopper means, even if the cartridge set in the casing receives a force that separates from the casing due to the reaction of the fluid pressure (water pressure, etc.) of the fluid to be processed guided into the cartridge. The stopper means for restricting the movement of the cartridge restrains the movement of the cartridge, so that the supply pipe connecting portion provided on the blocking wall and the introduction portion of the cartridge are fitted, and the discharge pipe connecting provided on the blocking wall It is possible to maintain the fitting state between the head and the cartridge lead-out part, effectively preventing liquid leakage from the connection part between the supply pipe connection part and the introduction part and the connection part between the discharge pipe connection part and the lead-out part. Can be suppressed.

It is preferable to be configured to be elastically deformable between the end portion and the second connection end portion.

  By configuring the stopper means in this way, the stopper means and the casing can be integrated. Furthermore, since the support is configured to be elastically deformable between the first connection end and the second connection end, it is formed in the casing even when the stopper means and the casing are integrated. It is possible to easily insert the movement restricting portion into the concave portion formed on the side wall side of the cartridge via the penetrating portion.
