In other words, when the first convex portion 53A is in the circumferential side groove 27A, the holding state in which the handle member 40 is attached to the housing member 20 is maintained. 53 A of 1st convex-shaped parts can enter into 27 A of circumferential direction side groove|channels, when it exists in a holding|maintenance position. That is, when the first convex portion 53A is in the holding position, the housing member 20 can be rotated. 53 A of 1st convex-shaped parts cannot enter into 27 A of circumferential direction side groove|channels, when it exists in a release position. That is, when the first convex portion 53A is at the release position, the housing member 20 cannot be rotated.

As shown in FIGS. 7 and 8 , the second guided member 54 is connected to the operating member 51 in the same manner as the first guided member 53 . The second guided member 54 moves laterally as the operation member 51 moves laterally. The second guided member 54 has a second convex portion 54A. The second convex portion 54A protrudes radially inward. The second convex portion 54A is arranged inside the groove portion 27 of the housing member 20 . The second convex portion 54A is arranged only within the axial side groove 27B of the groove portion 27 . The second convex portion 54A is provided so as to be freely movable in the circumferential direction as the housing member 20 rotates about the rotation axis C. As shown in FIG.

As shown in FIGS. 7 and 8, the second guided member 54 has a locking portion 54B. The locking portion 54B is provided at the left end portion of the second guided member 54 . As shown in FIG. 7, when the second guided member 54 is moved leftward to the holding position, the locking portion 54B is fitted into the locking recess 40B of the handle member 40 and locked. . The handle member 40 is held in this state. When the handle member 40 is rotated about the rotation axis C in the held state, the rotation is transmitted to the second guided member 54 locked to the locking recess 40B, and the second convex portion of the second guided member 54 is rotated. The power is transmitted from 54A to the housing member 20 through the side wall of the axial side groove 27B, and the housing member 20 rotates.

As shown in FIG. 8, the second guided member 54 is disengaged from the engaging recess 40B of the handle member 40 when it is moved rightward to the release position. The handle member 40 is released in this state. When the handle member 40 is rotated around the rotation axis C in the released state, the rotation is not transmitted to the second guided member 54 because the engagement with the engagement recess 40B is released, and only the handle member 40 rotates. do. As a result, the screw engagement between the internal thread 40A of the handle member 40 and the external thread 21A of the peripheral wall portion 21 of the housing member 20 can be released, and the handle member 40 can be removed from the housing member 20. FIG.

The restricting member 60 restricts the rotation range of the housing member 20 with respect to the main body member 10 . As shown in FIG. 6, the restricting member 60 is formed in a plate shape having an arcuate cross section. The restricting member 60 is arranged between the inner peripheral surface of the body portion 3 and the outer peripheral surface of the peripheral wall portion 21 of the housing member 20 (see FIG. 2). In the assembled state, the regulating member 60 is arranged adjacent to the guide member 52 on the end surface in the circumferential direction. In the assembled state, the inner peripheral surface of the regulating member 60 slidably contacts the outer peripheral surface of the peripheral wall portion 21 .

As shown in FIG. 6, the regulating member 60 has a regulating recess 61 and an engaging projection 62. As shown in FIG. The restriction recess 61 is formed by recessing the left end surface of the restriction member 60 . The first protrusion 24 of the housing member 20 is arranged in the restricting recess 61 . Each restriction recess 61 has a closed side restriction surface 61A and an open side restriction surface 61B. One end face 24A in the circumferential direction of the first projecting portion 24 of the housing member 20 in the closed position contacts the closed-side restricting surface 61A. The other end surface 24B in the circumferential direction of the first projecting portion 24 of the accommodating member 20 in the open position contacts the open-side restricting surface 61B. In this manner, the restricting member 60 restricts the rotation range of the accommodating member 20 by the closed side restricting surface 61A and the open side restricting surface 61B of the restricting concave portion 61 .

In the case of this embodiment, as shown in FIG. 6, the restricting recesses 61 are formed at two positions in the restricting member 60 in the circumferential direction. Two first protrusions 24 of the housing member 20 are arranged in each of the restriction recesses 61 . One restricting recess 61 is open in the circumferential direction. An opening-side restricting surface 61B in one restricting concave portion 61 is formed by the guide member 52 arranged adjacently.

As shown in FIG. 6 , the engaging protrusion 62 protrudes radially outward from the outer peripheral surface of the restricting member 60 in a convex shape. The engaging projection 62 engages with the engaging groove 3B of the body portion 3 in the assembled state. In this embodiment, three engaging protrusions 62 are provided. The three engaging protrusions 62 are arranged side by side in the circumferential direction on the outer peripheral surface of the restricting member 60 .

The restricting member 60 is provided movably between a first position and a second position. At the first position, the regulating member 60 allows only rotation within the rotation range between the open position and the closed position of the housing member 20 . In the second position, the regulating member 60 allows the housing member 20 to rotate to the removal position. A first position of the restricting member 60 is a position where the engaging projection 62 is engaged with the engaging groove 3B. A second position of the regulating member 60 is a position where the engaging projection 62 is leftwardly displaced from the engaging groove 3B.

In the water discharging device 1, the water purifying cartridge 90 has a columnar shape that can be accommodated in the space 20A in the accommodating member 20, and the water is reformed by circulating from the outer peripheral surface side to the inner peripheral surface side. The water purification cartridge 90 has a fitting protrusion 91 that fits into the fitting recess 22B at one end in the axial direction. The inner space of the water purification cartridge 90 and the communication hole 23A at the center of the shaft portion 23 of the housing member 20 communicate with each other by fitting the fitting protrusion 91 into the fitting recess 22B. The water reformed by the water purification cartridge 90 , that is, purified water flows out through the communication hole 23</b>A and the channel inside the main body member 10 .

The operation of the water discharging device 1 having the above configuration will be described. FIG. 10 shows a state in which the housing member 20 is at the closed position, the restricting member 60 is at the first position, and the release operation portion 50 is at the holding position. When the housing member 20 is in the closed position, the on-off valve 30 is in a state in which the through hole 31A in the fixed valve body 31 and the through hole 32A in the movable valve body 32 are not communicating with each other, that is, the main body, as shown in FIG. A flow path between the member 10 and the housing member 20 is closed. Therefore, water is not supplied to the space 20A inside the housing member 20, and purified water is not discharged.

When the release operation portion 50 is in the holding position, the engaging portion 54B of the second guided member 54 is engaged with the engaging recess 40B of the handle member 40 (see FIG. 8). In other words, the handle member 40 is held in a state where it is attached to the housing member 20 . Therefore, the rotation operation of the handle member 40 is transmitted to the housing member 20, and the housing member 20 can be rotated between the open position and the closed position.

FIG. 12 shows a state in which the handle member 40 is operated to rotate from the state where the housing member 20 is at the closed position shown in FIG. 10 to the open position. When the housing member 20 is in the open position, the on-off valve 30 is in a state where the through hole 31A in the fixed valve body 31 and the through hole 32A in the movable valve body 32 communicate with each other as shown in FIG. and the housing member 20 are opened. As a result, water is supplied from the body member 10 side into the space 20A in the housing member 20, passes through the water purification cartridge 90, and flows out as purified water.

When the housing member 20 is in the closed position, as shown in FIG. 10, the first projecting portion 24 contacts the closing-side restricting surface 61A of the restricting recessed portion 61 at one end surface 24A in the circumferential direction, and further rotation is prevented. is regulated. When the housing member 20 is in the open position, as shown in FIG. 12, the first protrusion 24 contacts the opening-side restricting surface 61B of the restricting recess 61 at the other end surface 24B in the circumferential direction. Thus, the housing member 20 is only allowed to rotate between the open position and the closed position when the restricting member 60 is at the first position.

The handle member 40 is removed from the housing member 20 when the water purification cartridge 90 is replaced or the like. When removing the handle member 40, the release operation portion 50 is moved from the holding position to the release position. The release operation portion 50 is allowed to switch between the holding state and the release state only when the housing member 20 is in the closed position.

The release operation unit 50 can switch between the holding state and the release state by moving the operation member 51 left and right (see FIGS. 7 and 8). By setting the release operation portion 50 to the released state, the locking portion 54B is disengaged from the locking concave portion 40B. As a result, when the handle member 40 is rotated, only the handle member 40 rotates, and the handle member 40 can be removed from the housing member 20 as shown in FIG.

When the release operation portion 50 is in the holding position, the first convex portion 53A of the first guided member 53 is arranged at a position overlapping the circumferential side groove 27A of the housing member 20 in the circumferential direction (see FIG. 9). . Therefore, the first convex portion 53A can enter into the circumferential groove 27A when the housing member 20 is rotated to the open position, and the rotational movement of the housing member 20 between the open position and the closed position is possible. do not interfere.

When the release operation portion 50 is in the release position, the first convex portion 53A of the first guided member 53 is arranged at a position axially displaced from the circumferential groove 27A of the housing member 20 (see FIG. 9). Therefore, when the housing member 20 is rotated from the closed position to the open position, the first convex portion 53A interferes with the side wall of the axial side groove 27B. This prevents the housing member 20 from rotating to the open position.

When the housing member 20 is in the open position, the release operation part 50 cannot be switched from the holding state to the release state. A state in which the housing member 20 is in the open position is a state in which water is supplied to the water purification cartridge 90 in the space 20A. In order to prevent the handle member 40 from being removed when water is flowing into the space 20A, the release operation portion 50 is maintained in a held state when the housing member 20 is in the open position. there is

When the housing member 20 is in the open position, the first convex portion 53A of the release operation portion 50 in the held state is positioned inside the circumferential side groove 27A of the groove portion 27 of the housing member 20 . Therefore, when the operation member 51 is operated rightward, the first convex portion 53A interferes with the side wall of the circumferential side groove 27A. In this way, when the housing member 20 is in the open position, the holding state in which the handle member 40 is attached to the housing member 20 is maintained.

When replacing parts of the housing member 20 or overhauling the water discharging device 1, the housing member 20 is removed. When removing the housing member 20, the engagement between the engaging protrusion 62 of the restricting member 60 and the engaging groove 3B of the main body portion 3 is released, and the restricting member 60 is moved from the first position to the second position.

FIG. 15 shows a state in which the containing member 20 is in the closed position and the restricting member 60 is in the second position. The second position of the regulating member 60 is a position moved leftward from the first position. When the regulating member 60 is at the first position, the first projecting portion 24 of the accommodating member 20 is arranged inside the regulating recessed portion 61 (see FIG. 10). By moving the regulating member 60 from the first position to the second position on the left, the first projecting portion 24 is disengaged from the regulating recessed portion 61 as shown in FIG. 15 . In other words, when the regulating member 60 is moved to the second position, the closing-side regulating surface 61A of the regulating concave portion 61 is positioned outside the rotational trajectory of the first projecting portion 24 when the accommodating member 20 rotates. . In this way, the restrictions on the rotation range of the first projecting portion 24 are released, and the housing member 20 can be rotated to the removal position.

When the housing member 20 is between the closed position and the open position, the axial end surface 25A of the second projecting portion 25 overlaps the right side surface of the holding member 34 (see FIGS. 11 and 13). reference). In other words, the housing member 20 is restricted from being removed by the axial end surface 25A of the second projecting portion 25 being in contact with the right side surface of the holding member 34 . By rotationally moving the housing member 20 to the removal position, the restriction on removal is released and the housing member 20 can be removed.

FIG. 16 shows a state in which the housing member 20 is rotated from the state shown in FIG. 15 and moved from the closed position to the removed position. The removal position of the housing member 20 is the position opposite to the moving direction from the closed position to the open position. As shown in FIG. 17 , when the housing member 20 is at the removal position, the three second protrusions 25 are positioned so as to overlap the shape of the keyhole portion 34C in the holding member 34 . Therefore, the second projecting portion 25 can exit the keyhole portion 34C and move to the left of the holding member 34 . As a result, the housing member 20 is removed as shown in FIG.

When the housing member 20 is rotated to the removal position, the release operation part 50 is in the release position. In this state, the first convex portion 53A of the first guided member 53 is arranged at a position overlapping the retraction groove 27C of the housing member 20 in the circumferential direction (see FIG. 9). Therefore, the first convex portion 53A can enter the retraction groove 27C when the housing member 20 rotates to the removal position, and does not hinder the rotational movement of the housing member 20 to the removal position.

As described above, the water discharger 1 according to this embodiment includes the housing member 20, the handle member 40, and the release operation portion 50. As shown in FIG. The housing member 20 houses the water purification cartridge 90 . The handle member 40 is detachably attached to the housing member 20 and closes the space 20A in the housing member 20 in which the water purification cartridge 90 is housed. A handle member 40 manipulates the supply of water to the water purification cartridge 90 . The release operation unit 50 switches between a holding state in which the handle member 40 is attached to the housing member 20 and a release state in which the handle member 40 can be removed from the housing member 20 . In the held state, the release operation part 50 enables the operation of supplying water to the water purification cartridge 90 by the handle member 40 . In the released state, the release operation part 50 disables the water supply operation to the water purification cartridge 90 by the handle member 40 .

With such a configuration, the water discharger 1 can block the space 20A that houses the water purification cartridge 90 by the handle member 40, and can perform water discharge stop operation. The water discharger 1 can prevent the handle member 40 from coming off from the housing member 20 when the water discharge stop operation is performed by the handle member 40 by setting the release operation portion 50 to the holding state. Therefore, the water discharger 1 is convenient to use.

The water discharger 1 includes an on-off valve 30 . The on-off valve 30 opens and closes a channel for supplying water to the water purification cartridge 90 by operating the handle member 40 . The release operation unit 50 can switch from the holding state of the handle member 40 to the release state only when the on-off valve 30 is in the closed state. Therefore, it is possible to prevent the handle member 40 from coming off when the on-off valve 30 is open.

The water discharging device 1 includes a main body member 10 . The body member 10 rotatably supports the housing member 20 . The housing member 20 is rotatable between an open position where the on-off valve 30 is opened and a closed position where the on-off valve 30 is closed. Only when the release operation portion 50 is in the released state, the handle member 40 is allowed to rotate relative to the housing member 20 and becomes detachable. Thus, the water discharger 1 cannot rotate the housing member 20 relative to the main body member 10 in a state in which the water purification cartridge 90 is replaceable and the handle member 40 is removed. Therefore, the water discharger 1 can suitably prevent water from being supplied while the handle member 40 is removed, such as when the water purification cartridge 90 is replaced. The water discharging device 1 does not need to separately provide a valve mechanism for preventing or reducing the flow of water to the water purification cartridge 90 when the water purification cartridge 90 is replaced, and can realize a simple configuration.

In the water discharging device 1 , a groove portion 27 is formed on the outer peripheral surface of the housing member 20 . The groove portion 27 has a circumferential groove 27A extending in the circumferential direction of the housing member 20 and an axial groove 27B extending axially continuously from the circumferential groove 27A. The release operation portion 50 has a first convex portion 53A as a convex portion arranged in the groove portion 27 . When the first convex portion 53A is in the axial side groove 27B, the first convex portion 53A is movable between a holding position where the handle member 40 is held and a release position where the handle member 40 is released. The first convex portion 53A cannot move from the holding position to the releasing position in a state in which it is inside the circumferential groove 27A. The release operation portion 50 allows rotational movement between the open position and the closed position in the housing member 20 when the first convex portion 53A is in the holding position. The release operation portion 50 prevents rotational movement of the housing member 20 between the open position and the closed position when the first convex portion 53A is at the release position. Thus, in the water discharger 1 , the housing member 20 cannot rotate with respect to the main body member 10 when the handle member 40 is removed from the housing member 20 . Therefore, when removing the handle member 40, it is not necessary to hold the housing member 20 so as not to rotate it. As a result, the handle member 40 can be easily removed from the housing member 20 .

The water discharging device 1 includes a body portion 3 as a cover portion. The body portion 3 covers one end side of the housing member 20 in the axial direction. The handle member 40 is attached to the other end side of the housing member 20 in the axial direction. In the installed state, the housing member 20 has a rotation axis C along the horizontal direction when it rotates with respect to the main body member 10 . The release operation part 50 is arranged on the lower side near the front of the main body part 3 when viewed from the front in the installed state. In this way, in the water discharger 1, the release operation part 50 is arranged on the front side lower side of the main body part 3, so that the release operation part 50 on the front side of the water discharger 1 has good visibility and operability. It is possible to achieve compatibility with good design.

The water discharging device 1 includes a regulating member 60 . The restricting member 60 restricts the rotation range of the housing member 20 with respect to the main body member 10 . The housing member 20 is positioned between an open position in which the on-off valve 30 is opened, a closed position in which the on-off valve 30 is closed, and a removal position where removal from the main body member 10 is permitted. 10 is freely rotatable. The regulating member 60 is between a first position that allows only rotation within a rotation range between the open position and the closed position in the housing member 20 and a second position that allows rotation to the removal position in the housing member 20. is movably provided.

The water discharging device 1 can restrict the movement of the housing member 20 to the removal position by setting the regulation member 60 to the first position, and rotates the housing member 20 to the removal position by setting the regulation member 60 to the second position. be able to Therefore, the water discharging device 1 can prevent the accommodating member 20 from unexpectedly falling off during normal use such as opening and closing operations of the on-off valve 30 . Therefore, the water discharger 1 can reliably perform the opening/closing operation of the on-off valve 30 .

In the water discharging device 1, the housing member 20 has a first protrusion 24 that protrudes in the radial direction. The regulating member 60 has regulating surfaces 61A and 61B as first regulating surface portions that contact the circumferential end surfaces 24A and 24B of the first projecting portion 24 to regulate the rotation range between the open position and the closed position. Therefore, the rotation range of the housing member 20 can be appropriately restricted.

In the water discharging device 1, the housing member 20 has a second projecting portion 25 projecting in the radial direction. The water discharging device 1 includes a holding member 34 as a second restricting surface portion that contacts the axial end surface of the second protruding portion 25 to restrict removal of the housing member. Therefore, removal of the housing member 20 can be properly restricted.
