  In Patent Documents 1 and 2, there is no particular problem as long as the content is a lightweight object such as a battery. However, when the contents are relatively heavy and the contents are constantly subjected to a force in the protruding direction during use, there are the following problems.

  If an external impact is applied to the main body case, a large load may act on the contents inserted into the main body case in the pop-out direction. It is necessary to prevent the contents from popping out by being received by the hinge member and the lid member.

  Here, in the above-mentioned Patent Documents 1 and 2, from the relation that the force in the protruding direction is received by the shaft support portion of the hinge member and the engagement protrusion of the lid member, in particular, the shaft support portion of the hinge member. On the side, there are many design constraints such as the bearing and its mounting and the shaft portion of the hinge member requiring strength.

  In view of such circumstances, in the present invention, in a state where the opening of the accommodation chamber to be attached is closed, the content that is inserted in one direction from the opening in the accommodation chamber protrudes outward from the opening. An object of the present invention is to reduce a design restriction on a pivotal support portion of the hinge member by preventing a load in the protruding direction applied to the contents from being applied to the pivotal support portion of the hinge member. It is said.

  The present invention is attached to the opening of the accommodation chamber to be attached so as to be openable or closable, and in the closed state, the contents inserted in one direction from the opening in the accommodation chamber to the back are the openings. An opening / closing lid device that prevents the outer cover from popping out from the outside, and is a hinge member that is pivotally supported by the opening so as to be pivotable, and that makes the pressing portion abut against and separate from the contents in the storage chamber by the rotation. And a lid member that is slidably connected to the hinge member and that is integrally rotated with the hinge member and is slid to the closed position of the opening in a state where the pressing portion is in contact with the contents. The lid member is directed to a load receiving portion provided on the attachment object by sliding to the closed position at a position opposite to the shaft support side of the hinge member across the pressing portion. Protrusion And at least one of the lid member and the hinge member at a position on the side of the shaft support the load receiving portion provided on the mounting target in a state where the pressing portion is in contact with the contents. The projecting portion on the shaft support side and the projecting portion on the opposite shaft support side receive the load in the pop-out direction applied to the contents by contact with the corresponding load receiving portion. It is characterized by being configured.

  In the description of this configuration, with respect to the installation form of the projection on the shaft support side, in the form provided on both the shaft support side of the hinge member and the shaft support side of the hinge member in the lid member, or in the lid member A configuration in which the hinge member is provided only on the shaft support side or a configuration in which the hinge member is provided only on the shaft support side can be employed.

  And according to this structure, when the contents in the attachment object are inserted and the hinge member and the lid member are closed, a load in the protruding direction acts on the contents. The load is received by the projecting portion and the projecting portion on the opposite shaft support side and the load receiving portion corresponding thereto.

  As a result, the load bearing capability of the hinge member and the lid member is increased, so that the contents are prevented from easily jumping out of the storage chamber even when the load is applied.

  In addition, as can be seen from the above description, in the present invention, it is not necessary to increase the strength of the pivot support portion of the hinge member as in the conventional example, so that restrictions on designing the pivot support portion are reduced. become able to.

  By the way, the lid member is provided with a latching portion made of an elastically deformable tongue piece that is inserted into an engagement portion provided in the attachment object by sliding to the closed position, and on the distal end side of the latching portion. Can be configured to be provided with a claw portion that is hooked in the disengagement direction while being locked to the engagement portion.

  With this configuration, the form in which the lid member is held in the closed position becomes clear.

  The present invention relates to an opening / closing lid device that prevents contents inserted in one direction from the opening in the accommodation chamber to jump out from the opening in a state in which the opening of the accommodation chamber to be attached is closed. In this case, it is possible to reduce a design restriction on the shaft support portion of the hinge member by preventing a load in the protruding direction applied to the contents from being applied to the shaft support portion of the hinge member.

  The water treatment device 1 is configured to generate ozone water in this embodiment, and includes a device main body 2, an electrolytic module 3, and the like. In the figure, reference numeral 5 denotes a display unit such as an operation display lamp.

  The apparatus main body 2 includes a skeleton part 20, a module housing part 21, a water supply pipe line 22, a water discharge pipe line 23, a power feeding part 24, a water path cover 25, a rear cover 26, a maintenance cover 27, a module support 28 and the like.

  The skeleton part 20 includes a partition wall 29a, a ceiling wall 29b, a bottom wall 29c, and a rear wall 29d.

  The module housing portion 21 is a space in which the electrolytic module 3 is detachably attached, and is a space surrounded by the partition wall 29 a, the ceiling wall 29 b, the bottom wall 29 c and the rear wall 29 d of the skeleton portion 20, and the maintenance cover 27. It is said that.

  The shape of the module storage unit 21 composed of this space, which is a cross section in the horizontal direction in the vertical direction, is rectangular, but two adjacent surfaces among the four surfaces arranged in the circumferential direction are the skeleton portion 20. The partition wall 29a and the rear wall 29d are closed, and the remaining two surfaces are open to the outside. The two surfaces thus opened are closed by the cover main body 27a and the extension wall portion 27b of the L-shaped 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 water channel cover 25 and the rear cover 26 are detachably attached to the skeleton 20. The maintenance cover 27 is attached to the skeleton part 20 via the module support 28 so as to be opened and closed, and is closed so as to cover the module storage part 21.

  The module support 28 is attached to the skeleton part 20 so as to be openable and closable. When the module storage part 21 is closed together with the maintenance cover 27, the module support 28 comes into contact with the electrolytic module 3 inserted into the module storage part 21. The movement in the direction of removal is regulated and held. The maintenance cover 27 and the module support 28 are made of, for example, a synthetic resin.

  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.

  The apparatus main body 2 corresponds to an “attachment object” described in the claims, the module storage portion 21 corresponds to an “accommodation chamber” described in the claims, and the electrolytic module 3 corresponds to the claims. The maintenance cover 27 corresponds to the “lid member” described in the claims, and the module support 28 corresponds to the “hinge member” described in the claims.

  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.

  The electrolysis module 3 is configured so that it can 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.

  As shown in FIGS. 5 and 6, the water supply conduit 22 and the water discharge conduit 23 are arranged in a lateral orientation, and the connection port 22 a of the water supply conduit 22 and the connection port 23 a of the water discharge conduit 23 are connected to each other. The partition wall 29a is opened so as to face the module housing portion 21 by projecting into the module housing portion 21 through the partition wall 29a.

  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.

  Further, the power feeding unit 24 is provided on the ceiling wall 29b, and as shown in FIG. 4, 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. It has been. 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 as shown in FIG. 7, the water supply port 31 and the water discharge port 32 with which the electrolysis 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.

  Further, as shown in FIGS. 6 and 7, a guide portion 29 e 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 body 2. Are provided.

  Specifically, as shown in FIG. 6, the guide portion 29 e is provided on the upper surface of the bottom wall 29 c of the apparatus main body 2 and is formed as two parallel projecting rails. Further, as shown in FIG. 7, 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 e. Has been.

  The length direction of the two protruding rails as the guide portion 29 e 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.

  As shown in FIG. 3, 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 respectively a sealing material (O-ring). Etc.) It is sealed through 4 and is difficult to come off.

  Specifically, the inner diameters of the connection port 22a and the water discharge port 32 of the water supply line 22 are larger than the outer diameters of the connection port 23a and the water supply port 31 of the water discharge line 23, and the connection port 22a of the water supply line 22 The connection port 23 a of the water discharge conduit 23 is fitted to the inner diameter side of the water discharge port 32 while being fitted to the outer diameter side of the water supply port 31.

  From such a form, the connection port 22a and the water discharge port 32 of the water supply line 22 will be referred to as a female shape, and the connection port 23a and the water supply port 31 of the water supply line 23 will be referred to as a male shape. Thereby, attaching the electrolytic module 3 to the module storage part 21 upside down is avoided.

  The sealing material 4 is attached to each base side of the outer diameter side of the connection port 23 a of the water discharge pipe 23 and the outer diameter side of the water supply port 31, and water is supplied to the connection port 22 a of the water supply pipe line 22. When the outlet 31 is fitted and the water discharge port 32 is fitted to the connection port 23a of the water discharge pipe 23, the fitting surface is tightly fitted by the sealing material 4, so that the fitting does not easily come off. And the mating surface is sealed.

  Here, when the electrolytic module 3 is attached to the module housing portion 21 of the apparatus main body 2, as shown in FIG. 1, the module housing section 21 is moved outward 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 portion of the module housing portion 21 while being open.

  Thereby, the pushing operation of the electrolysis module 3 is stably induced by the fitting of 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 29e on the electrolysis module 3 side. In this way, the strip-shaped pieces that are the two connection terminals 33 of the electrolytic module 3 are placed in the two grooves 24 a of the power feeding unit 24 of the apparatus main body 2.

  At this time, the two connection terminals 33 elastically deform the curved one of the pair of power supply terminals 24b and 24c in the two grooves 24a of the power supply unit 24, With the reaction force (elastic restoring force), the connection terminal 33 is strongly sandwiched between the pair of power supply terminals 24b and 24c and is brought into a pressed state, that is, a complete push-in state. On the other hand, the water supply port 31 and the water discharge port 32 over the connection port 23a of the water discharge line 23 are completely fitted over the seal material 4 in the connection port 22a of the water supply line 22, respectively.

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

  By the way, when the water treatment apparatus 1 is operated in a state where the electrolytic module 3 is attached to the apparatus main body 2, the raw material water is vigorously introduced into the electrolytic module 3. The introduction pressure (see FIG. 10) acts.

  Since the state where the maintenance cover 27 and the module support 28 are closed is firmly held when this load F is applied, the electrolytic module 3 is devised to prevent the electrolytic module 3 from easily jumping out of the module housing portion 21. This will be described below.

  First, as shown by the two-dot chain line in FIG. 14, the maintenance cover 27 and the module support 28 in the open position are rotated in the direction of the arrow 100 in FIG. The opening is closed.

  At this time, as shown in FIG. 11, the projecting portion 73 on the shaft support side of the module support 28 enters the load receiving portion 83 on the shaft support side, and the projecting portion 73 is loaded in the recess as the load receiving portion 83. It comes into contact with the inner surface facing F.

  Thereafter, the maintenance cover 27 is slid toward the rear wall 29d of the skeleton part 20 in the direction of the arrow 200 in FIG. 14, so that the locking part 71 on the side opposite to the shaft support of the maintenance cover 27 is anti-reverse as shown in FIG. The engaging portion 81 on the shaft support side and the locking portion 72 on the shaft support side enter the engaging portion 82 on the shaft support side, so that the claw portion 71a of the locking portion 71 is engaged with the engaging portion 81. And the claw portion 72 a of the locking portion 72 is hooked on the opening edge of the engaging portion 82. At the same time, the upper and lower protrusions 74 on the side opposite to the shaft support are assigned to the upper and lower load receiving portions 84 of the skeleton 20.

  When the water treatment device 1 is operated in the state where the maintenance cover 27 is closed as described above, a load F in the protruding direction acts on the electrolysis module 3, but as shown in FIG. 10 and FIG. Since the protrusions 73 and 74 on both sides of the pressing portion 28e, that is, on the shaft support side and the opposite shaft support side, and the corresponding load receiving portions 83 and 84 are in contact with each other, the load F You will receive it face to face.

  Therefore, the load F is transmitted to the skeleton part 20 via the module support 28 and the maintenance cover 27. That is, the load F is received not only by the module support 28 and the maintenance cover 27 but also by the whole structure in which the module support 28 and the maintenance cover 27 and the skeleton 20 are combined. As a result, the shaft support portion of the module support 28 does not receive the load F directly, and it is not necessary to consider the strength against the load F. Therefore, design restrictions can be reduced, and a simple shaft support portion structure can be employed.

  Therefore, it can be said that the load bearing capacity of the module support 28 and the maintenance cover 27 is increased, so that even when the load F is applied, the electrolytic module 3 is prevented from easily jumping out of the module housing portion 21.

  As described above, in the embodiment to which the present invention is applied, the introduction pressure (load F) of the raw water acting on the electrolysis module 3 in accordance with the operation of the water treatment apparatus 1 is changed to the skeleton via the maintenance cover 27 and the module support 28. Since the load-bearing capacity of the module support 28 and the maintenance cover 27 is increased by being transmitted to the part 20, even when the load F acts, the electrolytic module 3 can easily jump out of the module housing part 21. It will be blocked.

  Moreover, as can be seen from the above, in this embodiment, it is not necessary to increase the strength of the support portion of the module support 28 of the maintenance cover 27 relative to the apparatus body 2 as in the conventional example. It becomes possible to reduce the restrictions on designing.

  In addition, this invention is not limited only to the said embodiment, It can change suitably in the range equivalent to the claim and the said range.

  (1) In the above embodiment, the water treatment apparatus 1 is exemplified as an application target of the present invention, but the present invention is not limited to this.

  As an object to which the present invention is applied, for example, although not shown, an electric actuator including a detachable battery can be used. In that case, the battery corresponds to the contents described in the claims, and the main body of the control electric actuator corresponds to the attachment object described in the claims.

  (2) In the above embodiment, the shaft support side protrusion 73 is provided on the module support 28 and the shaft support side protrusion 74 is provided on the maintenance cover 27. However, the shaft support side protrusion 73 is provided on the module support 28. It may be provided not only on the 28 side but also on the maintenance cover 27 side or both. In short, what is necessary is just to provide a protrusion and a load receiving portion for receiving the load F on the shaft support side and the opposite shaft support side which are both sides of the pressing portion 28e.

  (3) In the above embodiment, an example is given in which the maintenance cover 27 is L-shaped, but the present invention is not limited to this.

  Although the maintenance cover 27 is not shown, for example, the extension wall 27b may be omitted, or the extension wall 27b and the ceiling wall 27c may be omitted.

  In that case, the water channel cover 25 needs to be configured to extend to the same position as the rear wall 29d, and the tongue piece is formed on the long side of the cover body 27a of the maintenance cover 27 on the opposite side of the module support 28. It is necessary to adopt a configuration in which the locking portion 71 made of is protruded so as to be orthogonal to the shaft support side and parallel to the cover body 27a. Note that the tongue piece as the locking portion 71 in this case is protruded so as to be parallel to the cover main body 27a by being protruded once toward the inside of the cover main body 27a and then bent by 90 degrees.

  With this configuration, when the maintenance cover 27 and the module support 28 are closed, the rotation operation and the slide operation can be performed as in the above embodiment. Also in this case, the same operation and effect as in the above embodiment can be obtained.

  (4) In the above embodiment, the locking portion 71 on the opposite shaft support side and the locking portion 72 on the shaft support side have a male shape like a tongue piece, and the engagement portion 81 on the opposite shaft support side and the shaft support side Although the example which made the engagement part 82 the female shape like a hollow is given, this invention is not limited only to this.

  For example, although not shown in the figure, the opposite relationship, that is, the locking portion 71 on the opposite shaft support side and the locking portion 72 on the shaft support side are formed in a female shape like a hollow, and the engagement portion on the opposite shaft support side It is possible to make 81 and the engaging part 82 of a shaft support side into a male shape like a tongue piece.

  (5) In the above embodiment, the guide rails 51 and 52 are provided on the maintenance cover 27 and the guide grooves 61 and 62 are provided on the module support 28. However, the present invention is not limited to this. Absent.

  For example, although not shown in the figure, it is possible to provide guide grooves 61 and 62 on the maintenance cover 27 and guide rails 51 and 52 on the module support 28 in the opposite relationship.

  The present invention is attached to the opening of the accommodation chamber to be attached so as to be openable or closable, and in the closed state, the contents inserted in one direction from the opening in the accommodation chamber to the back are the openings. It is possible to use suitably for the opening-and-closing lid device which prevents jumping out from the outside.
