  BEST MODE FOR CARRYING OUT THE INVENTION Best modes for carrying out the present invention will be described in detail below with reference to the accompanying drawings.

  1 to 11 show an embodiment of the present invention. In the figure, 1 indicates the entire water treatment apparatus.

  The water treatment device 1 is configured to generate ozone water in this embodiment, and includes a device main body 2, an electrolysis module 3, and the like.

  The apparatus main body 2 is provided with a module housing portion 21, a water supply conduit 22, a water discharge conduit 23, a power feeding portion 24, and the like, and a water passage cover 25, a rear cover 26, and a maintenance cover 27 are provided.

  The water channel cover 25 and the rear cover 26 are detachably attached, but the maintenance cover 27 can be opened and closed via a hinge (not shown). A module support 28 is provided inside the maintenance cover 27 of the apparatus body 2. The module support 28 is attached to the rear cover 26 via a hinge (not shown) so as to be opened and closed. The module support 28 is in contact with the electrolytic module 3 attached to the module housing portion 21 in a closed state, and regulates and holds the movement of the electrolytic module 3 in the removal direction, and is described in the claims. Functions as a holding means.

  The module housing portion 21 is a space in which the electrolytic module 3 is detachably attached, and is a space surrounded by a partition wall 29a, a ceiling wall 29b, a bottom wall 29c, a rear cover 26, and a maintenance cover 27. The partition wall 29 a is provided to partition the module housing portion 21 and the arrangement space of the water supply pipeline 22 and the water discharge pipeline 23.

  A water supply port 31 of the electrolysis module 3 is connected to the water supply line 22, and a water discharge port 32 of the electrolysis module 3 is connected to the water discharge line 23. The power feeding unit 24 is connected to the connection terminal 33 of the electrolytic module 3.

  The electrolysis module 3 has a cylindrical outer shape and a length dimension set to be larger than a diameter dimension, and a water electrolysis unit (not shown) is incorporated therein. This water electrolysis part can be removed from the inside of the electrolysis module 3.

  On the outer peripheral surface of the electrolytic module 3, a water supply port 31 and a water discharge port 32 are provided above and below in the longitudinal direction. Further, two connection terminals 33 that are electrically connected to the electrodes of the water electrolysis unit (not shown) are provided on the upper end surface of the electrolysis module 3.

  In the case of such a water treatment device 1, ozone water is generated by applying a voltage to the electrode of the water electrolysis unit and performing electrolysis of the raw material water while passing the raw material water through the water electrolysis unit. However, inorganic substances such as calcium ions and magnesium ions contained in the raw water are deposited and deposited in the vicinity of the electrodes after long-term use. In addition, the electrode may be worn or the ion exchange membrane of the water electrolysis unit may be deteriorated due to long-term use. For this reason, it is preferable to periodically refresh or replace the water electrolysis unit of the electrolysis module 3.

  Therefore, the electrolytic module 3 of this embodiment is configured so as to be relatively easily attached to and detached from the module housing portion 21 of the apparatus main body 2 from one direction, and will be described below.

  Specifically, the water supply pipe 22, the water discharge pipe 23, and the power supply unit 24 provided in the apparatus main body 2 are provided so as to face the module storage unit 21.

  The water supply conduit 22 and the water discharge conduit 23 are arranged in a lateral orientation, and the connection port 22a of the water supply conduit 22 and the connection port 23a of the water discharge conduit 23 penetrate the partition wall 29a, and the module housing portion 21. It is opened so as to face the module housing portion 21 by protruding inward.

  Further, the water supply joint 22 b of the water supply pipe line 22 is provided so as to protrude outward from the side surface opposite to the module housing portion 21 in the apparatus main body 2. The water discharge joint 23 b of the water discharge pipe 23 is provided so as to protrude outward from the ceiling wall 29 b of the apparatus main body 2.

  Furthermore, the power feeding unit 24 is provided on the ceiling wall 29b, and the two grooves 24a are provided so as to open to the lower surface of the ceiling wall 29b and to open toward the side surface of the ceiling wall 29b. These two grooves 24a are provided so as to extend in a straight line, and the following connection terminals 33 of the electrolytic module 3 are inserted in a straight line from one direction with a gap.

  A pair of power supply terminals 24b and 24c are arranged in the two grooves 24a. One power supply terminal 24b is formed in a band plate shape and is fixed, and may be hereinafter referred to as a fixed-side power supply terminal. In addition, the other power supply terminal 24c is formed in a curved shape and is flexible or movable, and may be hereinafter referred to as a movable-side power supply terminal.

  When the connection terminal 33 is inserted into each of the two grooves 24a, the movable side power supply terminal 24c is elastically deformed by the connection terminal 33, and the reaction force (elastic restoring force) causes the movable side power supply terminal 24c and the fixed side. Since the power supply terminal 24b comes into pressure contact by strongly sandwiching the connection terminal 33, both the power supply terminals 24b and 24c and the connection terminal 33 are electrically connected. For this reason, the minimum gap among the opposing gaps between the movable side power supply terminal 24 c and the fixed side power supply terminal 24 b is set smaller than the thickness of the connection terminal 33.

  And the water supply port 31 and the water discharge port 32 with which the electrolytic module 3 is provided are provided so that both may open toward the same direction.

  Further, the two connection terminals 33 provided in the electrolytic module 3 are both strip-shaped pieces and are provided so as to protrude upward in a state of being separated in parallel to the upper end surface of the electrolytic module 3. In the case of the connection terminal 33 installed in this way, it can be said that it faces the outer peripheral surface of the electrolytic module 3.

  Furthermore, a guide portion 29 d and a guided portion 34 for guiding the pushing operation of the electrolytic module 3 are provided on the lower end surface of the electrolytic module 3 and the bottom wall 29 c of the apparatus main body 2.

  Specifically, the guide portion 29d is provided on the upper surface of the bottom wall 29c of the apparatus main body 2, and is formed as two parallel protruding rails. Further, as shown in FIG. 6, the guided portion 34 is provided on the lower end surface of the electrolytic module 3, and includes two groove-like rails that are individually fitted to the two protruding rails as the guide portion 29 d. Has been.

  The length direction of the two protruding rails as the guide portion 29 d is parallel to the length direction of the two grooves 24 a of the power feeding portion 24. Further, the length direction of the two groove-like rails as the guided portion 34 is parallel to the width direction of the two strip-like pieces as the connection terminals 33.

  The connection of the water supply port 31 and the water discharge port 32 of the electrolysis module 3 to the connection port 22a of the water supply line 22 and the connection port 23a of the water discharge line 23 of the apparatus main body 2 is sealed through a sealing material (O-ring or the like) 4 respectively. It is hard to come off with being done.

  Specifically, the connection port 22 a of the water supply pipe 22 is fitted to the outer diameter side of the water supply port 31, while the connection port 23 a of the water discharge pipe 23 is fitted to the inner diameter side of the water discharge port 32. It has become so.

  That is, the inner diameters of the connection port 22 a and the water discharge port 32 of the water supply pipeline 22 are larger than the outer diameters of the connection port 23 a and the water supply port 31 of the water discharge channel 23. Therefore, the connection port 22a and the water discharge port 32 of the water supply pipe line 22 are referred to as a female shape, and the connection port 23a and the water supply port 31 of the water discharge line 23 are referred to as a male shape. Thereby, attaching the electrolytic module 3 to the module storage part 21 upside down is avoided.

  In addition, the sealing material 4 is each attached to the outer diameter side of the connection port 23a of the water discharge pipe 23 and the outer diameter side of the water supply port 31, and the water supply port is connected to the connection port 22a of the water supply line 22. When 31 is fitted and the water discharge port 32 is fitted to the connection port 23a of the water discharge line 23, the fitting surface is tightly fitted by the sealing material 4, so that the fitting is not easily removed. And the fitting surface is sealed.

  Next, with reference to FIG. 9 to FIG. 11, a state when the electrolytic module 3 is attached to or removed from the module housing portion 21 of the apparatus main body 2 will be described.

  When the electrolytic module 3 is attached, as shown in FIG. 1, the module housing 21 is opened to the outside by opening the maintenance cover 27 and the module support 28 of the apparatus main body 2. The electrolytic module 3 is pushed in a straight line in one direction from the open part.

  As shown in FIG. 9, as a step before the pushing, the grooved rail that is the guide portion 29 d of the electrolytic module 3 is fitted to the protruding rail that is the guided portion 34 of the apparatus body 2, and the electrolytic module 3 are aligned so that the strip plate-like pieces which are the two connection terminals 33 are applied to the inlets of the two grooves 24a of the power feeding section 24 of the apparatus main body 2. In this state, the water supply port 31 is close to the connection port 22 a of the water supply line 22, and the water discharge port 32 is only close to the connection port 23 a of the water discharge line 23. ing.

  When the pushing operation is performed, first, the electrolytic module 3 is pushed by fitting the protruding rail which is the guided portion 34 on the apparatus main body 2 side and the grooved rail which is the guide portion on the electrolytic module 3 side. The operation is stably induced, and the strip-like pieces that are the two connection terminals 33 of the electrolytic module 3 are inserted into the two grooves 24 a of the power feeding unit 24 of the apparatus main body 2.

  At this stage, as shown in FIG. 10, the two connection terminals 33 are connected to the curved power supply terminal 24 c of the pair of power supply terminals 24 b and 24 c in the two grooves 24 a of the power supply unit 24. Due to the elastic deformation, the connection terminal 33 is strongly sandwiched between the pair of power supply terminals 24b and 24c by the reaction force (elastic restoring force), that is, is in a fully pressed state. . On the other hand, the water supply port 31 fits shallowly on the inner diameter side of the connection port 22a of the water supply conduit 22 and the water discharge port 32 fits shallowly on the outer diameter side of the connection port 23a of the water discharge conduit 23. The seal material 4 of the water supply port 31 does not reach the connection port 22a, and the water discharge port 32 does not reach the seal material 4 of the connection port 23a of the water discharge pipe 23, respectively.

  Subsequently, when the electrolysis module 3 is further pushed into the back, as shown in FIG. 11, the connection terminal 33 enters a deeper state between the pair of power supply terminals 24b and 24c, and the water supply conduit The water supply port 31 is connected to the connection port 22 a of 22, and the water discharge port 32 is completely fitted over the seal material 4 to the connection port 23 a of the water discharge pipe 23.

  As described above, even when the connection terminal 33 is deeply inserted between the pair of power supply terminals 24b and 24c, the connection terminal 33 is pressed between the pair of power supply terminals 24b and 24c. The state is maintained.

  In this state, the sealing material 4 is elastically compressed and deformed to seal the fitting surface, and the frictional resistance of the sealing material 4 becomes a resistance when the electrolytic module 3 is pulled out. Even if the pressure when the raw material water is supplied to the electrolysis module 3, the electrolysis module 3 is not easily detached from the module housing portion 21.

  As described above, the electrolytic module 3 is attached by the guide part on the electrolytic module 3 side and the guided part 34 on the apparatus main body 2 side, the connection terminal 33 of the electrolytic module 3, and the groove 24 a of the power feeding part 24 on the apparatus main body 2. Thus, the pushing operation of the electrolytic module 3 is stably guided at both ends in the length direction, that is, up and down, so that the electrolytic module 3 can be easily and quickly attached.

  Moreover, before the water supply port 31 and the water discharge port 32 are completely fitted into the connection port 22a of the water supply line 22 and the connection port 23a of the water discharge line 23, the connection terminal 33 is brought into pressure contact with the power supply terminals 24b and 24c. Thus, it can be said that the mounting operation of the electrolytic module 3 can be performed relatively easily and reliably, for example, the posture of the electrolytic module 3 is not easily collapsed in the pushing process.

  And when removing the electrolytic module 3 from the apparatus main body 2, what is necessary is just to remove by pulling the electrolytic module 3 in a straight line from the operation | movement contrary to the above-mentioned attachment case, ie, the module accommodating part 21.

  Also at this time, the electrolytic module 3 is long due to the guide part on the electrolytic module 3 side and the guided part 34 on the apparatus main body 2 side, the connection terminal 33 of the electrolytic module 3, and the groove 24 a of the power feeding part 24 of the apparatus main body 2. Since it is guided stably at both ends in the direction, that is, up and down, the electrolytic module 3 can be easily and quickly removed.

  If the electrolytic module 3 is removed in this manner, a water electrolysis unit (not shown) inside the module can be replaced with a new one, and the replacement operation can be easily performed.

  As described above, according to the embodiment to which the present invention is applied, the connection terminal 33 of the electrolytic module 3 is fed to the power supply of the apparatus body 2 simply by pushing the electrolytic module 3 into the module housing portion 21 of the apparatus body 2 from one direction. The water supply port 31 and the water discharge port 32 of the electrolysis module 3 are respectively connected to the water supply line 22 and the water discharge line 23 of the apparatus body 2 while being electrically connected to the unit 24. On the other hand, the electrolytic module 3 attached to the apparatus main body 2 can be removed simply by pulling it in a straight line in the direction opposite to the pushing direction in the attaching operation.

  This makes it possible for the user of the water treatment apparatus 1 to attach and remove the electrolytic module relatively easily and quickly, thereby minimizing the use interruption time of the water treatment apparatus 1 and the like. Convenience is improved.

The present invention is not limited to this, and the opposite relationship, that is, the connection port 22a and the water discharge port 32 of the water supply pipe line 22 are formed into a male shape, and the connection port 23a and the water supply port of the water discharge line 23 are provided. It is possible to make 31 into a female shape.
