Description

  The present invention relates to a water treatment apparatus, and more particularly, to a water treatment apparatus suitable for application to a pure water production apparatus that produces pure water from raw water such as tap water.

  A pure water production apparatus is widely used as an apparatus for easily producing a small amount of pure water in a school chemical laboratory or a hospital. In FIG. 3, the external appearance of the conventional pure water manufacturing apparatus is shown. The pure water manufacturing apparatus 10 </ b> A has a processing chamber in which a substantially cylindrical container (tubular housing) 11 is filled with an ion exchange resin 12 and supplies raw water into the processing chamber. In the central portion of the cylindrical housing 11 on the processing chamber side, a water collecting pipe 14 for collecting treated water treated with the ion exchange resin 12 through a water collecting portion 13 is disposed. An opening having an inner screw formed in the periphery is provided at the upper part of the cylindrical housing 11, and a raw water inlet for supplying tap water to the ion exchange resin 12 is provided in a lid (upper lid) 15 screwed to the opening. 16 and a treated water outlet 17 through which pure water treated by the ion exchange resin 12 and collected by the water collecting pipe 14 flows out.

  For example, an electrical conductivity meter (not shown) that measures the electrical conductivity of the treated water is disposed on the upper portion of the upper lid 15, and the quality of the treated water is displayed or the deterioration of the water quality is notified by an alarm. For this purpose, four studs 18 are arranged on the top of the top lid 15. As a result of continuous operation of the pure water production apparatus, when deterioration of the quality of the produced pure water is detected, the upper lid 15 is removed from the cylindrical housing 11, and the ion exchange resin 12 inside is replaced with new or regenerated ions. After replacing with a replacement resin, the operation is restarted. Such a type of pure water production apparatus 10A is described in, for example, Patent Document 1.

  In many cases, the pure water production apparatus 10A is often provided with a sink such as a hand-washer or a sink. In such a case, the raw water inlet 16 is a tap faucet by a tube made of vinyl chloride or a rubber hose. Connected to. Similarly, one end of a tube made of vinyl chloride or a rubber hose is connected to the treated water outlet 17, and the other end of the tube or hose is used as a substitute for a pure water supply faucet. A user who uses pure water receives pure water from a pure water production apparatus using a portable container such as a beaker, a wide-mouth bottle, or a plastic container, and transports it to a place where the pure water is used.

JP-A-9-271770

  By the way, pure water contains no chlorine component, and therefore, pure water has no sterilizing action. For this reason, when a tube made of vinyl chloride or the like is used for supplying pure water, various bacteria are propagated in the tube and slime deposits are generated on the inner surface of the tube. Since such deposits deteriorate the quality of the pure water used, there is a problem that the tube must be frequently washed and the maintenance operation of the pure water production apparatus is increased. In order to avoid such problems, if pipes and hoses are used instead of tubes and hoses for the treated water outlet, there will be incidental piping work on site when installing the deionized water production apparatus, and the deionized water production apparatus will be simple. This is contrary to the user's desire to install the device. In addition, each time the ion exchange resin 12 is replaced, it is necessary to remove the metal pipe from the pure water production apparatus, which causes another burden when maintaining and operating the pure water production apparatus.

  Further, in the pure water production apparatus, some pure water flows out from the faucet even after the injection of pure water from the faucet into the portable container is completed and the main valve of the raw water is closed. For this reason, in order to receive the pure water which flows out, it is desirable to install the drainage sink below the faucet. The drainage sink is also used for washing the portable container with pure water prior to injection of pure water into the portable container. However, installing a new drainage sink for the pure water production apparatus is also an incidental work, contrary to the desire of the user who wants to install the pure water production apparatus easily. In place of this, the installation of the pure water production apparatus adjacent to the existing drainage sink is a great restriction on the installation location of the pure water production apparatus.

  The problem of the conventional pure water production apparatus is not limited to the pure water production apparatus, but is a problem common to water treatment apparatuses that treat raw water using a filter medium such as an ion exchange resin.

  In view of the above, the present invention can be applied to a deionized water production apparatus, and replaces a tube made of vinyl chloride or a rubber hose that easily propagates germs with a metal pipe for supplying treated water. It is an object of the present invention to provide a water treatment device that can be installed easily without incidental work such as plumbing work and can reduce the burden of maintenance.

  Furthermore, the present invention can be installed without any additional incidental work such as adding a drainage sink for a faucet for supplying treated water, and does not cause any significant restrictions on the installation location. An object is to provide a processing apparatus.

  In order to achieve the above object, a water treatment apparatus according to a first aspect of the present invention includes a housing in which a filter medium and a water collecting pipe are disposed, an opening in an upper portion thereof, and a raw water inlet that communicates with the filter medium. A treatment water outlet that communicates with the water collection pipe, and an upper lid that is detachably fixed to the housing and closes the opening; a container base supported by the upper lid on the upper lid; and one end of the treatment lid A metal pipe that communicates with the water outlet and opens at the other end of the container base is provided.

  In a preferred aspect of the present invention, the container base is supported by a drainage sink that receives treated water flowing out of the metal pipe, and the drainage sink is fixed to the upper lid. In this case, since the drainage sink is disposed adjacent to the container base, it is not necessary to separately arrange the drainage sink, or restrictions such as disposing the water treatment device adjacent to the existing drainage sink. Is removed.

  Furthermore, it is also a preferable aspect of the present invention that the container base supported by the drainage sink is formed in a bowl shape (or a grating shape). In this case, when the portable container is placed on the container stand, the possibility that the bottom of the container gets wet with water is reduced. In addition, when washing the portable container, the risk of the treated water splashing in the bottom surface of the drainage sink is reduced.

  A water treatment apparatus according to a second aspect of the present invention includes a housing having a filter medium and a water collection pipe disposed therein, an opening at the top, a raw water inlet communicating with the filter medium, and a treated water stream communicating with the water collection pipe. An upper lid that is detachably fixed to the housing and closes the opening; a drainage sink supported by the upper lid on the upper lid; one end communicating with the treated water outlet and the other end And a metal pipe opening at an upper portion of the drainage sink.

  According to the water treatment apparatus according to the first aspect of the present invention, by using a metal pipe at the treated water outlet, propagation of germs inside the pipe is suppressed, and therefore, connected to the treated water outlet. The need for frequent cleaning of the piping is eliminated. In addition, the container base is supported by the upper lid that closes the opening of the housing, and the other end of the metal pipe having one end connected to the treated water outlet of the upper lid is disposed on the upper portion of the container base. There is no need to remove the metal pipe from the top cover when replacing the pipe. For this reason, the burden of the maintenance operation of a pure water manufacturing apparatus is reduced.

  According to the water treatment apparatus according to the second aspect of the present invention, the drainage sink is installed at the time of installation of the water treatment apparatus by the configuration in which the drainage sink is disposed below the other end of the metal pipe forming the faucet of the treated water. Therefore, it is possible to easily install the water treatment apparatus, because no additional work is required or the restriction of disposing the water treatment apparatus adjacent to the existing drainage sink is removed.
