The more the secondary side piping is placed at a location farther from the bathroom wall, the more the bathroom space is squeezed. In order to avoid this, it is preferable to effectively use the space near the wall of the bathroom. This is a common problem not only in water purifiers that purify raw water, but also in raw water reformers that reform raw water. From this point of view, the inventor of the present invention has recognized that there is room for improvement in the technology disclosed in Patent Document 1.

An aspect of the present invention has been made in view of such problems, and one of the objects thereof is to provide a technique that can utilize the wall-side space of the bathroom wall.

A first aspect of the present invention for solving the aforementioned problems is a raw water reformer. The raw water reforming device of the first aspect comprises a device body fixed to a bathroom wall, and the device body receives raw water sent from a primary side pipe through either a raw water supply channel or a reformed water supply channel. and an internal water channel is provided to guide water to the secondary side pipe, and the internal water channel is provided with a downstream side water channel that guides water sent from the raw water supply channel and the reforming water supply channel to the secondary side pipe, The downstream water channel includes a first downstream water channel portion extending toward the bathroom wall side toward the downstream side of the downstream water channel.

According to the first aspect, it is possible to realize a layout in which the secondary hose is arranged at a location near the bathroom wall, compared to a structure in which the downstream water channel does not have the first downstream water channel.

Such a second external pipe connection portion 80 is provided at a position overlapping the cartridge 54 in the X direction when viewed from the Z direction (viewpoint in FIG. 6). The second external pipe connection portion 80 is provided closer to the bathroom wall portion 16 than the cartridge 54 when viewed in the Y direction (viewpoint in FIG. 5).

The effects of the above-described first devised point will be described.

The downstream water channel 36 has a first downstream water channel portion 36 a extending toward the bathroom wall portion 16 side as it goes downstream of the downstream water channel 36 . Therefore, compared to a structure in which the downstream water channel 36 does not have the first downstream water channel portion 36a, a layout in which the secondary side pipe 32 is arranged near the bathroom wall portion 16 can be realized. Along with this, the space near the wall near the bathroom wall portion 16 can be effectively used to arrange the secondary side pipe 32 .

(A) The downstream water channel 36 has a second downstream water channel portion 36b extending in the Y direction from the first downstream water channel portion 36a. Therefore, it is possible to realize a layout in which the secondary side pipe 32 is arranged at a location avoiding the space between the cartridge 54 and the bathroom wall portion 16 . Accordingly, interference of the secondary side pipe 32 with the device main body 52 and the bathroom wall portion 16 can be easily avoided compared to the case where the secondary side pipe 32 is arranged between the cartridge 54 and the bathroom wall portion 16 . Accordingly, the usability of the water discharging device 20 (shower head) connected to the secondary pipe 32 is improved.

(B) The second piping member 68 is connected to a part (the first piping member 66) of the device main body 52 so as to be rotatable about the Y-direction axis. Therefore, by rotating the second piping member 68, the movable range of the secondary side piping 32 connected to the second piping member 68 can be increased. Accordingly, the usability of the water discharging device 20 (shower head) connected to the secondary pipe 32 is improved.

The upstream water channel 34 has a first upstream water channel portion 34 a that extends toward the bathroom wall portion 16 side toward the upstream side of the upstream water channel 34 . Therefore, compared to a structure in which the upstream water channel 34 does not have the first upstream water channel portion 34a, a layout in which the primary side pipe 26 is arranged near the bathroom wall portion 16 can be realized. Along with this, the space near the wall near the bathroom wall portion 16 can be effectively used to arrange the primary side pipe 26 .

In addition, as shown in FIGS. 12 and 13 , the upstream water channel 34 includes an upstream indoor water channel portion 34 c provided in the cartridge chamber 82 . The downstream water channel 36 also includes a downstream indoor water channel portion 36 d provided in the cartridge chamber 82 . The raw water supply channel 28 has a smaller diameter than the upstream indoor water channel portion 34 c , and the downstream indoor water channel portion 36 d has a smaller diameter than the raw water supply channel 28 .

Next, another feature related to the first contrivance will be described. The raw water reformer 50 includes a valve mechanism 100 capable of switching the water flow path of the first internal water channel 24 from among the reformed water supply channel 30 and the raw water supply channel 28 . The valve mechanism 100 of this embodiment can open and close the raw water supply passage 28 . The valve mechanism 100 of this embodiment includes a valve seat 104 provided in the raw water supply passage 28 and having a valve hole 102 formed therein, and a valve body portion 106 capable of opening and closing the valve hole 102 . The valve body portion 106 of this embodiment is provided in the cartridge 54 . The valve hole 102 of the present embodiment is formed by the inner wall surface of the valve seat 104 itself, and is configured by a tapered surface whose inner diameter becomes smaller toward the return direction Pa2, which will be described later.

The raw water reformer 50 includes a water channel switching mechanism 110 that can switch the water flow path of the first internal water channel 24 from the reformed water supply channel 30 and the raw water supply channel 28 by operating the valve mechanism 100 . The channel switching mechanism 110 of this embodiment is incorporated in the first body member 62 .

The channel switching mechanism 110 includes a first operating member 112 operated to switch the water flow path of the first internal channel 24, a driven member 114 moved in conjunction with the first operating member 112, and the first operating member 112. and an interlocking mechanism 116 that interlocks the driven member 114 . Although the first operation member 112 in this embodiment is a push button that receives a pressing operation, it may be a rotary handle that receives a rotation operation.

The driven member 114 is inserted through a through hole formed at the bottom of the downstream chamber 82 a of the cartridge chamber 82 . A part of the driven member 114 is arranged in the cartridge chamber 82 , and the component parts of the channel switching mechanism 110 other than the driven member 114 are not arranged in the cartridge chamber 82 . The driven member 114 of the present embodiment can move the valve body portion 106 of the valve mechanism 100 by being moved in the operating direction Pa1 in conjunction with the first operating member 112 . The driven member 114 of the present embodiment can be moved so as to press the entire cartridge 54 provided with the valve body portion 106 of the valve mechanism 100 in the operating direction Pa1.

As shown in FIG. 8, the raw water reforming device 50 includes a biasing member 118 that biases the valve body 106 in the return direction Pa2 opposite to the operation direction Pa1 of the valve body 106 by the channel switching mechanism 110. . The urging member 118 of this embodiment is arranged between the inner bottom portion of the upstream chamber 82 b of the cartridge chamber 82 and the cartridge 54 , and urges the cartridge 54 integrally with the valve body portion 106 . The biasing member 118 is, for example, an elastic member such as a coil spring. The components of the channel switching mechanism 110 and the valve body 106 are moved against the biasing force of the biasing member 118 .

Return to FIG. The interlocking mechanism 116 includes a driving member 120 that moves in a direction different from the moving direction of the driven member 114 in conjunction with the first operating member 112 and pushes the driven member 114 in the operating direction Pa1.

FIG. 15 is a view of another operating state of the raw water reformer 50 viewed from the same viewpoint as in FIG. As shown in FIGS. 12 and 15, the interlocking mechanism 116 includes a position switching mechanism 122 capable of switching the position of the driven member 114 each time the first operating member 112 is operated. Although the position switching mechanism 122 of this embodiment is a thrust lock mechanism, it may be a heart cam mechanism, a rotating cam mechanism, a ratchet cam mechanism, or the like. Components of the position switching mechanism 122 of this embodiment include a sleeve 122a, a rotor 122b, and a driver 122c. The position switching mechanism 122 switches the position of the driven member 114 in the X direction each time the driven member 114 reciprocates in the operating direction Pa1 and the returning direction Pa2. Accordingly, the position of the valve body portion 106 in the X direction is switched.

The channel switching mechanism 110 of this embodiment holds either the closed position P1 in which the valve body 106 closes the valve hole 102 or the open position P2 in which the valve body 106 opens the valve hole 102 . The channel switching mechanism 110 switches the position of the cartridge 54 (valve body portion 106) between the closed position P1 and the open position P2 each time the first operating member 112 is operated.

The valve body portion 106 can move back and forth between a closed position P1 that contacts the valve seat 104 to close the valve hole 102, and an open position P2 that is separated from the valve seat 104 from the closed position P1 and opens the valve hole 102. . The advancing/retreating direction Pd of the valve body portion 106 of this embodiment is the X direction.

The channel switching mechanism 110 described above is arranged at a position overlapping the cartridge 54 in the X direction. The waterway switching mechanism 110 of the present embodiment is arranged at a position overlapping the cartridge 54 in the return direction Pa2 and on the downstream side and the upper side of the cartridge chamber 82 in the X direction. At least a part of the constituent parts of the channel switching mechanism 110 should satisfy this condition. In this embodiment, this condition is satisfied by components including the driven member 114 of the channel switching mechanism 110 . Thus, by disposing the channel switching mechanism 110 at a position that does not overlap the cartridge 54 in the X direction, it is possible to reduce the size of the device main body 52 in the Y and Z directions.

Next, other features of the device main body 52 will be described. FIG. 16 is an assembly drawing of the components shown in FIG. FIG. 17 is a diagram schematically showing the BB section of FIG. FIG. 18 is a view of the first piping member 66 viewed from arrow C in FIG.

The supporting body member 58 includes a pipe housing portion 58 a that houses a portion of the first pipe member 66 . The pipe accommodating portion 58a includes a pair of side wall portions 58b arranged with a portion of the first pipe member 66 interposed therebetween. The pair of side wall portions 58b are spaced apart in the Y direction.

The first piping member 66 includes a first main body pipe portion 66a in which a portion of the first internal water channel 24 is formed. An insertion hole 66b for inserting and withdrawing the first fastener 74 is formed in the first main body tube portion 66a.

The first piping member 66 includes a backlash restricting portion 66c provided outside the first main body pipe portion 66a. Here, “the outside of the first main body pipe portion 66a” means a location different from the first internal water channel 24 formed by the first main body pipe portion 66a and the hole penetrating the outside and inside of the first main body pipe portion 66a. Say things. The "hole" here is, for example, the insertion hole 66b.

A pair of backlash restricting portions 66c of this embodiment are arranged with a gap therebetween in the Y direction. The pair of backlash restricting portions 66c are plate-shaped. Each of the pair of backlash restricting portions 66c is arranged at a position facing each of the pair of side wall portions 58b in the Y direction. The pair of backlash restricting portions 66c of the present embodiment are arranged between the pair of side wall portions 58b. The backlash restricting portion 66c of this embodiment has a planar backlash restricting surface 66d, and the side wall portion 58b has a planar opposing surface 58c facing the backlash restricting surface 66d.

The backlash restricting portion 66c comes into contact with the side wall portion 58b of the supporting main body member 58 when the first piping member 66 is about to rotate around the direction axis in the Z direction (direction Pr1 in FIG. 17). Specifically, the backlash restricting surfaces 66d of the pair of backlash restricting portions 66c are in contact with the opposing surfaces 58c of the pair of side wall portions 58b. Thereby, the backlash restricting portion 66c can restrict the movement of the first piping member 66 around the direction axis in the Z direction. The pair of looseness restricting portions 66c can restrict the movement so that the movable range of the first piping member 66 around the direction axis in the Z direction is 5° or less, for example.

(C) As a result, when the first piping member 66 is rotatably connected to the first piping connection portion 72 of the device main body 52, the first piping member 66 can be prevented from rattling. Along with this, a change in the position of the secondary side pipe 32 caused by rattling of the first pipe member 66 can be suppressed.

Please refer to FIGS. 9, 10 and 16. FIG. The raw water reforming device 50 is separate from the first piping member 66 and has a retainer 130 arranged outside the first piping member 66 . The outside of the first piping member 66 here is synonymous with the outside of the first main body pipe portion 66a described above. The retaining portion 130 of the present embodiment is provided on the side wall portion 58b of the supporting main body member 58. As shown in FIG. The direction in which the first pipe member 66 is pulled out from the first pipe connection portion 72 of the apparatus main body 52 is referred to as the withdrawal direction Pe1, and the direction opposite to the withdrawal direction is referred to as the insertion direction Pe2. The retaining portion 130 is provided so as to be positioned in the detaching direction Pe<b>1 with respect to the first piping member 66 . The retainer 130 has a groove-like shape that opens in the insertion direction Pe2.

16 and 18 are referred to. The first piping member 66 includes an abutting portion 132 provided at a position facing the retaining portion 130 in the insertion direction Pe2. The first piping member 66 of the present embodiment includes a pair of abutting portions 132 provided at positions sandwiching the central axis Lc2 of the first upstream water channel portion 34a of the upstream water channel 34 therebetween. Each of the abutting portions 132 on one side has a plate shape. More specifically, one abutting portion 132 has a flat plate shape, and the other abutting portion 132 has a U-shaped bent plate shape. The surfaces of the pair of abutting portions 132 that face the retaining portions 130 are arcuate. The abutting portion 132 is arranged inside the retaining portion 130 .

The retaining portion 130 comes into contact with the abutting portion 132 to prevent the first pipe member 66 from coming off from the first pipe connecting portion 72 of the device main body 52 . Thereby, the connection strength of the first pipe member 66 to the first pipe connection portion 72 can be improved. In particular, there is an advantage that the first pipe member 66 can be prevented from coming off from the first pipe connection portion 72 without using the first fastener 74 .

(Second ingenuity point)
Next, the second contrivance of the raw water reformer 50 of this embodiment will be described. The second contrivance mainly concerns the cartridge 54 .

19 is a side view of cartridge 54. FIG. See also FIG. Cartridge 54 is an elongated body. The cartridge 54 includes an elongated reforming section 150 , a second internal water channel 152 provided inside the cartridge 54 , and cap members 154 and 156 attached to both ends of the reforming section 150 . The cap members 154 and 156 include a first cap member 154 on the operating direction Pa1 side (one side in the X direction) and a second cap member 156 on the return direction Pa2 side (the other side in the X direction). . In this embodiment, the operating direction Pa1 side is the upstream side of the cartridge chamber 82, and the returning direction Pa2 side is the downstream side of the cartridge chamber 82. As shown in FIG.

The reforming section 150 can pass raw water sent from the upstream indoor water channel portion 34c of the upstream water channel 34, and can generate reformed water by reforming the raw water with a reforming material in the course of passing the raw water. is. The reformer 150 of the present embodiment allows water to pass from the upstream water channel 34 to the second internal water channel 152 . The reforming section 150 and the second internal water channel 152 of this embodiment constitute the reformed water supply channel 30 . The reforming section 150 of the present embodiment has a tubular shape extending in the X direction, and a part of the second internal water channel 152 is formed inside the reforming section 150 . The modifying section 150 of the present embodiment is configured by accommodating a modifying material between a plurality of permeable membranes such as nonwoven fabrics. The modifier is, for example, activated carbon, calcium carbonate, or the like.

The second internal water channel 152 is provided with a straight portion 152a that forms a downstream portion of the second internal water channel 152 and linearly extends in the X direction.

The first cap member 154 has a cylindrical shape with a bottom, and a plurality of ribs 154a are formed on the outer periphery thereof.

20 is an enlarged view of FIG. 12. FIG. As shown in FIGS. 19 and 20 , the second cap member 156 includes a bottomed tubular end receiving portion 158 that receives the end portion of the reforming portion 150 . A plurality of rib portions 158 a are formed on the outer peripheral portion of the end receiving portion 158 so as to protrude outward.

The second cap member 156 includes, in addition to the end receiving portion 158, a cylindrical shaft portion 160 extending from the end receiving portion 158 in the X direction, and a bottomed cylindrical head portion 162 provided at the tip of the shaft portion 160. , provided. A part of the second internal water channel 152 is formed inside the shaft portion 160 and the head portion 162 . The head portion 162 separates the downstream water channel 36 and the reforming water supply channel 30 .

A water passage hole 164 is formed in the head portion 162 to allow the downstream water passage 36 and the reforming water supply passage 30 to communicate with each other. A plurality of water passage holes 164 are formed in the head portion 162 at intervals in the circumferential direction. A plurality of water passage holes 164 are formed so as to be positioned at substantially equal angular intervals. The water passage hole 164 has a first hole portion 164 a penetrating the outer peripheral wall portion 162 a of the head portion 162 and a second hole portion 164 b penetrating the top wall portion 162 b of the head portion 162 .

The cartridge 54 includes an external force receiving portion 166 to which an external force is applied via the driven member 114 of the channel switching mechanism 110 through user's operation. The top wall portion 162b of the head portion 162 constitutes the external force receiving portion 166 of the present embodiment. The external force receiving portion 166 of the present embodiment is pressed by the driven member 114 to receive an external force in the operating direction Pa1. The operating direction Pa1 of the present embodiment is one side of the X direction, and a rectilinear force is applied as an external force. The external force receiving surface 166a of the external force receiving portion 166 of this embodiment that receives the external force is a flat surface. This external force receiving surface 166a is provided so as to be substantially perpendicular to the advancing/retreating direction Pd (X direction) of the valve body portion 106. As shown in FIG.

The valve body portion 106 of the cartridge 54 is provided on the shaft portion 160 of the second cap member 156 . The valve body portion 106 can open and close the valve hole 102 by moving itself when the external force receiving portion 166 receives an external force. In this embodiment, when the external force receiving portion 166 receives an external force, the entire cartridge 54 including the valve body portion 106 can move.

The valve body portion 106 includes a plurality of flange portions 168 and 170 projecting radially outward from the shaft portion 160, and a mounting groove 174 in which a second seal member 172 is mounted. The plurality of flanges 168 and 170 include the first flange 168 on the side of the above-described operation direction Pa1 and the second flange 170 on the side of the return direction Pa2. A mounting groove 174 is formed between the first collar portion 168 and the second collar portion 170 . The second seal member 172 is an elastic body such as an O-ring.

The valve body portion 106 includes a seal surface 176 that seals between the valve seat 104 and the valve seat 104 by contacting the valve seat 104 . The seal surface 176 is provided at a position overlapping the valve seat 104 in the advancing/retreating direction Pd of the valve body portion 106 . When the seal surface 176 of this embodiment is in the closed position P1, the second seal member 172 is elastically deformed, and the seal surface 176 contacts the valve seat 104 via the second seal member 172. to seal. The sealing surface 176 of the present embodiment is configured by the outer surface of the first collar portion 168 on the return direction Pa2 side.

Such a valve body portion 106 is arranged between the external force receiving portion 166 and the reforming portion 150 in the X direction. In order to satisfy this condition, it does not matter whether or not it is arranged at a position overlapping the external force receiving portion 166 and the reforming portion 150 in the X direction.

The switching operation of the water flow path using the cartridge 54 will be described. When the first operating member 112 is operated, the interlocking mechanism 116 interlocks with the first operating member 112 to move the driven member 114 in the operating direction Pa1. When the driven member 114 is moved in the operating direction Pa1, an external force is applied from the driven member 114 to the external force receiving portion 166 of the cartridge 54, and the valve body portion 106 of the cartridge 54 is moved against the biasing force of the biasing member 118. . When the external force applied to the external force receiving portion 166 is released, the biasing member 118 pushes it back in the return direction Pa2. Through this series of movements, the position of the valve body portion 106 is switched between the closed position P1 and the open position P2.

As shown in FIG. 12, when the valve body portion 106 is at the closed position P1, from the upstream indoor water channel portion 34c of the upstream water channel 34 to the downstream indoor water channel portion 36d of the downstream water channel 36 through the reforming water supply channel 30. Reformed water is supplied. At this time, water flows through the reforming water supply channel 30 of the first internal water channel 24 as a water flow path (see arrow Fa).

On the other hand, as shown in FIG. 15, when the valve body portion 106 is at the open position P2, raw water is supplied from the upstream indoor water channel portion 34c through the raw water supply channel 28 to the downstream indoor water channel portion 36d. At this time, almost no water flows through the reformed water supply channel 30 because a large pressure loss is caused when water flows through the reformed water supply channel 30 (the reforming section 150 ). Therefore, when the valve body portion 106 is at the open position P2, water flows through the raw water supply channel 28 of the first internal water channel 24 as a water passage (see arrow Fb).

In this way, the valve body portion 106 of the cartridge 54 advances and retreats between the closed position P1 and the open position P2 when the external force receiving portion 166 receives an external force, thereby The water flow path can be switched from within the supply path 30 .

Effects associated with the above second device point will be described.

According to the cartridge 54 of the present embodiment, the external force receiving portion 166 receives the external force and the valve body portion 106 moves, thereby enabling switching of the water flow path within the first internal water channel 24 . Therefore, it is possible to switch the water flow path by a new technique.

Further, since the cartridge 54 includes the valve body portion 106, the valve body portion 106, which is a component of the valve mechanism 100, can also be replaced by replacing the cartridge 54. FIG.

The valve body portion 106 includes a seal surface 176 arranged at a position overlapping the valve seat 104 in the advancing/retreating direction Pd. Therefore, when the valve hole 102 is opened and closed by advancing and retracting the valve body portion 106 in the X direction, sliding of the movable element in contact with the valve hole 102 can be prevented. The “movable element” in this embodiment is the second seal member 124 . Accordingly, the external force to be applied when moving the valve body portion 106 back and forth can be reduced, and the external force to be input to the first operating member 112 of the channel switching mechanism 110 can be reduced.

The valve body portion 106 is arranged between the external force receiving portion 166 and the reforming portion 150 in the advancing/retreating direction Pd of the valve body portion 106 . Therefore, the size of the cartridge 54 in the advancing/retreating direction Pd can be reduced compared to the case where the valve body portion 106 is arranged on the opposite side of the reforming portion 150 to the external force receiving portion 166 in the advancing/retreating direction Pd.

The external force receiving surface 166a of the external force receiving portion 166 is a flat surface provided so as to be substantially perpendicular to the advancing/retreating direction Pd of the valve body portion 106. As shown in FIG. Therefore, when the driven member 114 presses the external force receiving portion 166 , it becomes easy to input a straight external force to the external force receiving portion 166 along the advancing/retreating direction Pd. Accordingly, the valve body portion 106 becomes easier to move straight along the advancing/retreating direction Pd, and the operation of the valve body portion 106 can be stabilized.

The water passage hole 164 formed in the head portion 162 has a first hole portion 164a penetrating the outer peripheral wall portion 162a of the head portion 162 . Therefore, the top wall portion 162b of the head portion 162 constitutes the external force receiving portion 166, and even under a structure in which it is difficult to form the water passage holes 164 in the top wall portion 162b, the water flow rate can be secured through the first hole portion 164a. .

Note that the upstream water channel 34 and the downstream water channel 36 are always in communication via the reforming water supply channel 30 . Therefore, water hammer can be prevented from occurring when switching the water flow path of the raw water reformer 50 .

Other features related to the second contrivance will be described. See FIG. The cartridge 54 includes a first guide portion 180 for guiding movement of the valve body portion 106 in the radial direction of a circle centered on the central axis Lc2 of the valve hole 102 . The first guide portion 180 of this embodiment is provided on the outer peripheral portion of the second collar portion 170 . The first guide portion 180 is provided on the operating direction Pa1 side of the head portion 162 . The first guide portion 180 of the present embodiment is a tapered surface whose diameter decreases toward the return direction Pa2 side.

The first guide portion 180 is capable of guiding the movement of the valve body portion 106 in the radial direction with contact with the valve hole 102 when the valve body portion 106 moves from the open position P2 to the closed position P1. The first guide portion 180 radially guides the central axis Lc1 of the cartridge 54 to approach the central axis Lc2 of the valve hole 102 . Accordingly, when the valve body portion 106 moves from the open position P2 to the closed position P1, the valve body portion 106 can be radially aligned with the valve hole 102 . Accordingly, the operational stability of the valve body portion 106 is improved.

The valve hole 102 has a tapered surface, and a second guide guides movement of the valve body 106 in the radial direction of the valve hole 102 when the valve body 106 moves from the open position P2 to the closed position P1. It can be said that it constitutes the part 182 .

The inner bottom surface of the head portion 162 is provided with a guide portion 184 that guides the water flowing in the X direction in the reforming water supply channel 30 to the first hole portion 164 a of the water passage hole 164 . The guide portion 184 is provided to protrude from the inner bottom surface of the head portion 162 in the X direction. The outer surface of the guide portion 184 is provided so as to extend toward the first hole portion 164a side of the water passage hole 164 in the direction of flow in the straight portion 152a of the reforming water supply passage 30 . The outer surface of the guiding portion 184 of the present embodiment has a conical shape concentric with the central axis Lc1 of the cartridge 54 .

The water flowing straight in the X direction in the straight portion 152a of the second internal water channel 152 collides with the guide portion 184, and the flow direction is directed toward the first hole portion 164a of the water passage hole 164. (see arrow Fc). As a result, water can smoothly flow from the reforming water supply channel 30 to the downstream water channel 36 through the first hole portion 164a. Accordingly, the pressure loss in the reforming water supply passage 30 can be reduced.

21 is a CC end view of FIG. 19. FIG. 20 and 21 are referred to. The cartridge 54 includes a flange facing portion 190 that faces the valve seat 104 on the side opposite to the valve seat 104 with respect to the first flange portion 168 , and a reinforcement provided between the first flange portion 168 and the flange facing portion 190 . a portion 192; The flange facing portion 190 of the present embodiment is configured by the end surface portion of the end receiving portion 158 in the advancing/retreating direction Pd. The reinforcement portion 192 has a role of reinforcing the first collar portion 168 and connects the first collar portion 168 and the collar facing portion 190 . The reinforcing portion 192 of the present embodiment is configured by plate-shaped ribs protruding from the outer peripheral portion of the shaft portion 160 toward the outer peripheral side. A plurality of reinforcing portions 192 of this embodiment are provided at substantially equal angular intervals in the circumferential direction of the shaft portion 160 .

When the sealing surface 176 of the first flange portion 168 is pressed against the valve seat 104 , the valve seat 104 applies a reaction force to the first flange portion 168 in the X direction. The reinforcing portion 192 distributes the reaction force applied to the first flange portion 168 by transmitting the reaction force of the first flange portion 168 to the flange facing portion 190 . As a result, the strength against the reaction force in the X direction applied to the first collar portion 168 can be improved.

When the valve body portion 106 is at the open position P2, the valve body portion 106 is held at the open position P2 while being pressed against the driven member 114 by the biasing force of the biasing member 118 . On the other hand, when the valve body portion 106 is at the closed position P1, the valve body portion 106 is held at the closed position P1 while being pressed against the valve seat 104 by the biasing force of the biasing member 118 .

The driven member 114 is in contact with the external force receiving portion 166 of the cartridge 54 when the valve body portion 106 is at the closed position P1. The water pressure applied to the cartridge 54 in the X direction changes according to the contact area S<b>1 of the driven member 114 with respect to the external force receiving portion 166 . explain in detail.

Please refer to FIG. The cartridge 54 has a first pressure-receiving surface 196 that receives water pressure in the return direction Pa2 in the X direction and transmits it to the valve body portion 106, and receives water pressure in the actuation direction Pa1 side in the X direction and transmits it to the valve body portion 106. A second pressure receiving surface 198 is provided. The first pressure-receiving surface 196 is a surface of the cartridge 54 facing the operating direction Pa1, and is at least partially provided on the end surface of the second cap member 156 . The second pressure receiving surface 198 is a surface of the cartridge 54 facing the return direction Pa2 side, and is provided at least partially on the external force receiving surface 166 a of the external force receiving portion 166 .

The area of the second pressure receiving surface 198 decreases as the contact area S1 increases, and increases as the contact area S1 decreases. The areas of the first pressure-receiving surface 196 and the second pressure-receiving surface 198 of the present embodiment are set so that the valve body portion 106 is pressed against the valve seat 104 on the return direction Pa2 side due to the differential pressure between the water pressures that they receive. In order to realize this, the size of the aforementioned contact area S1 is adjusted. This contact area S1 is set to a size of 3 to 30 [mm ² ], for example. If the contact area S1 is less than 3 [mm ² ], the pressing force applied to the valve body portion 106 may be insufficient. On the other hand, if the contact area S1 exceeds 30 [mm ² ], there is concern that the pressing force applied to the valve body portion 106 will be excessive. In this case, there is a concern that the operability will deteriorate as the external force to be applied to the external force receiving portion 166 increases through the first operation member 112 of the channel switching mechanism 110 .

(Second embodiment)
FIG. 22 is a front view showing the raw water reformer 50 of the second embodiment. The raw water reforming device 50 of the present embodiment is provided substantially symmetrically in the Y direction when viewed from the front side of the bathroom wall portion 16 . Other points are the same as the raw water reformer 50 of the first embodiment.

The protruding portion 52b of the device main body 52 of this embodiment protrudes from the main body portion 52a toward the side opposite to the faucet device 18 in the Y direction when viewed from the front side of the bathroom wall portion 16 . As a result, the secondary pipe 32 connected to the body portion 52a is less likely to interfere with the faucet device 18 and the primary pipe 26, and the water discharging device 20 (shower head) connected to the secondary pipe 32 is prevented from interfering. Usability becomes good.

The present invention has been described above based on the embodiments. Next, modified examples of each component will be described.

The primary side pipe 26 and the secondary side pipe 32 may not be hoses. These pipes 26 and 32 may be arranged inside the bathroom wall portion 16 or inside a member different from the device main body 52 .

An example has been described in which the "function" of the functional component 38 is to receive the load of the bathroom article 40 and the bather. This bathroom article 40 is not limited to a shower hook, and may be, for example, a shower head, a bath lid, a hose, or the like. The functional part 38 becomes a shower hook when receiving the load of the shower head, a bath lid hook when receiving the load of the bath lid, and a hose hook when receiving the load of the hose. Moreover, when the "function" of the functional part 38 is to receive the load of the bather, it may be a simple handrail or the like in addition to the slide bar. In addition, the "function" of the functional component 38 is a function related to the bathroom, and may be any function other than reforming water, and its specific example is not limited to the above example. .

The raw water reformer 50 does not have to be combined with the bathroom functional component 38 . The raw water reforming device 50 may serve as either one or both of the faucet device 18 and the water discharging device 20 .

Although the cartridge 54 has been described with purification of raw water as an example of reforming raw water, it is not limited to this. For example, a cosmetic ingredient, an odorous ingredient, a carbonic acid ingredient, or a hydrogen ingredient may be added.

(First ingenious point)
The first downstream water channel portion 36a may extend toward the bathroom wall portion 16 toward the downstream side. As long as this is satisfied, it may extend obliquely with respect to the direction axis of the Z direction, instead of extending linearly along the Z direction as in the embodiment. Further, in addition to extending continuously toward the bathroom wall 16 toward the downstream side as in the embodiment, it may extend toward the bathroom wall 16 in stages.

The second downstream water channel portion 36b may extend in the X direction from the first downstream water channel portion 36a, and the secondary pipe 32 may be connected to the downstream end thereof. This assumes that the secondary side pipe 32 is connected to the device main body 52 via a single pipe member 66 .

The downstream water channel 36 may not include the third downstream water channel portion 36c. Even in this case, the above effects (A) and (B) can be obtained. In this case, the second piping member 68 is composed of, for example, a straight pipe or the like.

The upstream water channel 34 may extend from the cartridge chamber 82 in the X direction or the Y direction, or may extend in the opposite direction to the bathroom wall portion 16 . The upstream water channel portion 34a may extend obliquely with respect to the direction axis of the Z direction, instead of extending linearly along the Z direction as in the embodiment. Further, in addition to extending continuously toward the bathroom wall 16 toward the upstream side as in the embodiment, it may extend toward the bathroom wall 16 in stages.

In order to obtain the effect of (C) described above, it is sufficient that the backlash restricting portion 66c of the first piping member 66 can restrict the movement of the first piping member 66 by contact with another member. The other member here is not limited to the supporting main body member 58, and may be a part of the device main body 52 such as the first main body member 62 and the second main body member 64, for example.

The retaining portion 130 may be provided on a member different from the supporting main body member 58 . For example, it may be provided on the second body member 64 .

The waterway switching mechanism 110 may be arranged at a position that does not overlap the cartridge 54 in the X direction and is shifted from the cartridge 54 in the Y direction or the Z direction.

The valve mechanism 100 may be provided separately from the cartridge 54 in order to obtain the effect described in the first aspect.

(Second ingenuity point)
The biasing member 118 may be arranged in the downstream chamber 82a of the cartridge chamber 82, and part of the driven member 114 may be arranged in the upstream chamber 82b. In this case, the operating direction Pa1 side in the X direction is the downstream side of the cartridge chamber 82 , and the return direction Pa2 side in the X direction is the upstream side of the cartridge chamber 82 .

The direction of the external force applied to the external force receiving portion 166 is not particularly limited. For example, the direction of rotation around the central axis Lc1 of the cartridge 54 may be used. The operation direction Pa1 of the channel switching mechanism 110 is the same.

It is only necessary for the valve body portion 106 to move when the external force receiving portion 166 receives the external force, and it is not essential that the entire cartridge 54 move.

The sealing surface 176 of the valve body portion 106 may close the valve hole 102 by directly contacting the valve seat 104 without the sealing member 172 interposed therebetween.

The position of the sealing surface 176 is not particularly limited. For example, the seal surface 176 may be provided at a position that does not overlap the valve seat 104 in the X direction and overlaps the valve seat 104 in the radial direction of the valve hole 102 . Also, the sealing surface 176 may be provided on the end receiving portion 158 or the like in addition to the first flange portion 168 .

Although an example in which the valve hole 102 is formed by the inner wall surface of the valve seat 104 has been described, the valve hole 102 may be formed at a location different from the inner wall surface of the valve seat 104 .

Although an example in which the valve seat 104 is a tapered surface has been described, it may be a flat surface or the like facing the seal surface 176 in the X direction. In any case, the sealing surface 176 is provided at a position overlapping the valve seat 104 in the X direction.

The second seal member 172 may be mounted in a mounting groove formed in the first internal water channel 24 . This means that the valve body portion 106 does not have to be provided with the second seal member 172 .

The head portion 162 may separate one of the upstream water channel 34 and the downstream water channel 36 from the reforming water supply channel 30 . Similarly, the water passage hole 164 may communicate one of the water passages with the reforming water supply passage 30 .

The water passage hole 164 may have only one of the first hole portion 164a and the second hole portion 164b. The water passage hole 164 may be formed at a location other than the head portion 162 . For example, the head portion 162 may not be formed in the second cap member 156 and the water passage hole 164 may be formed in the distal end portion of the shaft portion 160 .

The specific shape of the guiding portion 184 is not particularly limited as long as it can guide the water flowing through the reforming water supply channel 30 to the first hole portion 164 a of the water passage hole 164 .

Although the reinforcing portion 192 has been described using a plate-like rib as an example, the specific example is not particularly limited. For example, it may have a block shape or the like.

Although an example in which the external force receiving surface 166a of the external force receiving portion 166 is a flat surface has been described, it may be a hemispherical curved surface or the like.

An example has been described in which the raw water supply channel 28 is provided outside the cartridge 54 and the reforming water supply channel 30 is provided only inside the cartridge 54 . Alternatively, the raw water supply channel 28 may be provided inside the cartridge 54 and part of the reforming water supply channel 30 may be provided outside the cartridge 54 . Even in this case, the reforming section 150 that forms part of the reforming water supply path 30 may be provided in the cartridge 54 . In other words, at least part of the reforming water supply channel 30 should be provided in the cartridge 54 . In this case, the portion between the cartridge 54 and the cartridge chamber 82 becomes part of the reforming water supply path 30 . In this case, a valve seat 104 may be provided in the raw water supply passage 28 inside the cartridge 54, and the valve body portion 106 may be provided so as to be relatively movable with respect to other portions of the cartridge 54 (the reforming portion 150).

A specific example of the first internal water channel 24 of the device main body 52 is not particularly limited in order to obtain the effect described in the second device point. The first internal water channel 24 may not include the first downstream water channel portion 36a of the downstream water channel 36, for example. Moreover, the raw water reforming device 50 may be installed in a place different from the bathroom space, such as a sink or a washbasin cabinet.

The embodiments and modifications of the present invention have been described in detail above. All of the above-described embodiments and modifications merely show specific examples for carrying out the present invention. The contents of the embodiments and modifications do not limit the technical scope of the present invention, and many design changes such as alterations, additions, and deletions of constituent elements are possible without departing from the spirit of the invention. In the above-described embodiment, the content that allows such design changes is emphasized by adding notations such as "of the embodiment" and "in the embodiment", but even contents without such notations can be designed. Changes are allowed. Any combination of the above components is also effective as an aspect of the present invention.
