In addition, when “Shimizu” is selected, the flow path from the inlet 7 to the purification section 4 is selected, and the purified water is purified by using the water purification cartridge 13 to purify the tap water. Discharge from outlet 12. The characters described in the display portions 19a, 19b, 19c are not limited to the above-mentioned “Shimizu”, “Shower”, and “Raw”, and may be described with the characters upside down. . Furthermore, it may be a symbol or an illustration showing the switching state instead of the above character. Further, instead of characters, the switching position may be identified by a difference in color or shape. Further, the positional relationship between the display portions 19a, 19b, 19c of the switching operation portion 17 and the dot 20 of the upper casing 5a is changed, and the display portions 19a, 19b, 19c are provided in the upper casing 5a. It is also possible to provide a dot 20 on the surface 18a of the surface, and it is also possible to replace the dot 20 with a symbol or illustration.

Furthermore, as shown in FIG. 11, the display units 19a, 19b, 19c on the case body 5 side of the switching operation unit 17 described above are arranged so as to enter the inside of the case body 5, and this switching operation unit 17 of The display window 21 may be formed on the upper wall of the upper casing 5a in the intruded portion so that only the current switching state is displayed. The display window 21 may be formed so as to be symmetrical with respect to the central section S. For example, the display windows 21 are individually provided on the left and right side walls of the case body 5 with the central section S as the center. You may make it provide.

Therefore, the left and right arrangements of the switching operation unit 17 provided on one side of the water purifier main body 2, for example, the switching operation unit 17 shown in FIG. 2 is changed to the switching operation unit 17 shown in FIG. Even if the inlet 7 is attached to the faucet 3 with the water purifier body 2 that is switched to the left side being turned left and right, the raw water outlet 9 is located on the central section S where the center of the inlet 7 is located. The center of the shower discharge port 10 and the purified water discharge port 12 is arranged, so the position of the raw water discharge port 9, the shower discharge port 10 and the purified water discharge port 12 in the front-rear direction viewed from the user is the purifier body 2 Therefore, the same operability can be ensured regardless of whether the switching operation unit 17 is arranged on the left or right side.

[0044] Since the switching operation unit 17 is provided on either the left or right side of the water purifier main body 2, the number of parts can be reduced compared to the case where switching operation means are provided on the left and right sides as in the conventional water purifier. As a result, the water purifier 1 can be downsized.

Furthermore, since the switching operation part 17 is not arranged at a position that blocks the view below the raw water discharge port, the shower discharge port, and the water purification discharge port as in the conventional water purifier, the workability by blocking the view is improved. Can be prevented.

[0045] Then, the shape of the switching operation unit 17 is formed so as to be plane-symmetric with respect to the central section S, and the center of the rotation shaft 19 of the switching operation unit 17 is arranged on the central section S. By rotating the operation part 17, the flow path from the inlet 7 to the purification unit 4, the flow path from the inlet 7 to the raw water discharge port 9, and the flow path from the reception port 7 to the shower discharge port 10 are opened. Therefore, even if the water purifier body 2 is reversed left and right and the left and right positions of the switching operation unit 17 are switched, the operability of the switching operation unit 17 does not deteriorate. Can be improved.

[0046] In addition, the display units 19a, 19b, and 19c are arranged so as to be symmetrical with respect to the central section S, so that the left and right sides of the water purifier body 2 are reversed and the left and right sides of the switching operation unit 17 are reversed. Even when the position is changed and attached to faucet 3, it is the same as before reversing the right and left of water purifier body 2 In addition, the switching state by the switching operation unit 17 can be confirmed by the display units 19a, 19b, 19c provided in the water purifier body 2 or the switching operation unit 17.

[0047] Furthermore, since the characters or symbols written on the display units 19a, 19b, 19c of the water purifier body 2 are written horizontally along the front-rear direction, the switching operation unit 17 is arranged on either the left or right side. It can be read without any discomfort.

[0048] Since a confirmation window 15 that is plane-symmetrical with respect to the central section S is provided on the cover 14 of the water purification unit 4, the left and right sides of the water purifier 1 are reversed so that the left and right sides of the switching operation unit 17 are reversed. Even if the position of is replaced, the confirmation work of the water purification cartridge 13 by the confirmation window 15 can be performed in the same manner as before the water purifier 1 is inverted.

[0049] In the first embodiment described above, the water purifier 1 is fixed to the faucet 3 by the ring-shaped mounting jig 8, but the ring-shaped mounting jig 8 is attached to the water purifier body 2. It may be provided so as to be rotatable. With this configuration, it is not necessary to remove the water purifier 1 from the faucet 3 when switching the position of the switching operation unit 17 by reversing the left and right of the water purifier 1, and the position of the switching operation unit 17 can be easily changed to the left and right. Can be replaced.

In the first embodiment described above, the case where the switching operation unit 17 is formed in a substantially octagonal column shape has been described. However, the switching operation unit 17 is plane-symmetric with respect to the central section S. For example, an operation portion 17a shown in FIG. 12 that prevents slipping during operation is acceptable. Contrary to this, a small protrusion (not shown) that becomes a hooking force at a position on each surface of the octagonal prism is formed in a plane symmetrical with respect to the central section S. It may be provided. When this small protrusion is provided, this small protrusion may be replaced with the dot 20. In addition to the above, as a non-slip, a non-slip rubber or the like may be provided uniformly on the outer peripheral surface of the switching operation unit 17.

[0051] Further, as shown in FIG. 13, the switching operation unit 17 may be replaced with a switching operation unit (switching operation means) 17b having a lever protruding in the front-rear direction. When the mode shown in FIG. 13 is adopted, it is sufficient to provide a display unit corresponding to each of the lever positions corresponding to the switching angle of the switching operation unit 17b.

[0052] Next, a second embodiment of the present invention will be described with reference to Figs. In addition, this In the second embodiment, only the configuration of the switching operation unit and the display unit is different from that of the first embodiment. Therefore, the same portions are denoted by the same reference numerals, and redundant descriptions are omitted. To do.

[0053] As shown in FIGS. 14A and 14B, the water purifier 1 is formed in a substantially L-shape when viewed from the front with the water purifier body 2 and the water purification unit 4, and the water purification device on the opposite side of the water purification unit 4 A hole 30 extending in the vertical direction is formed on the end surface of the main body 2, and a switching lever (switching operation means) 31 projects from the hole 30 outward. The switching lever 31 is a slide-type lever which is formed so as to be plane-symmetric with respect to the central section S and is movable up and down. The switching lever 31 is provided with the first embodiment described above. A switching unit (not shown) similar to that in FIG. That is, by sliding the switching lever 31 up and down, a flow path (not shown) from the inlet 7 to the purification unit 4 formed inside the water purifier main body 2 and the raw water outlet 9 from the inlet 7 The flow path (not shown) to the inlet and the flow path (not shown) from the receiving port 7 to the shower discharge port 10 are each switched off.

[0054] The front and rear surfaces of the case body 5 of the water purifier body 2 are symmetrical with respect to the central section S, and a pair of displays that display the current switching position corresponding to the switching position by the switching lever 31. Portions 32a, 32b, and 32c are provided. More specifically, as shown in FIG. 14A, when the water purifier 1 is viewed from the front, the display unit is viewed from the top along the sliding direction of the switching lever 31, closest to the switching lever side of the outer peripheral portion of the case body 5. 32a, 32b, 32c are arranged in order, and in this display section 32a, 32b, 32c, “Shimizu”, “Shower”, “Raw” are displayed in order from the top corresponding to the switching position of the switching lever 31. The characters are written horizontally. These characters are also described in the same manner in a display section (not shown) provided at a position that is reversed in the front-rear direction, that is, at a position that is symmetric with respect to the central section S.

Therefore, according to the second embodiment described above, as in the first embodiment described above, the shape of the switching lever 31 is formed to be plane symmetric with respect to the central section S. Furthermore, by simply sliding the switching lever 31, the flow path from the inlet 7 to the purification unit 4, the flow path from the inlet 7 to the raw water outlet 9, and the shower 7 to the shower outlet 10 Therefore, even if the water purifier body 2 is reversed left and right and the left and right positions of the switching lever 31 are switched, the operability of the switching lever 31 is not deteriorated. In addition, since the display portions 32a, 32b, and 32c are also described at positions that are plane-symmetrical with respect to the central section S, there is no difference in visibility even if the left and right positions of the switching lever 31 are switched. . And since the characters described in the display parts 32a, 32b, 32c are written horizontally and along the vertical direction, it is advantageous in that the visibility of the user power standing in front of the water purifier 1 is improved.

[0056] In the second embodiment, the force is not limited to the force slide type using the slide type switching lever 31. As shown in FIG. 15, it is also possible to use a switching lever (switching operation means) 33 of a type that switches freely. Further, in addition to the switching levers 31, 33 protruding through the hole 30, for example, as shown in FIG. 16, it is supported on both the front and rear sides of the case body 5, and the operation position is the same as the switching levers 31, 33 described above. It is also possible to use a so-called dual-support type switching lever (switching operation means) 34. The switching lever 34 is also shaped like a plane with respect to the central section S.

Next, a third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, the purification unit 4 of the first embodiment is placed horizontally, and the purification unit 4 and the water purifier main body 2 are formed in an integral columnar shape. . For this reason, the same parts as those in the first embodiment described above are denoted by the same reference numerals and redundant description is omitted.

[0058] As shown in FIG. 17, the substantially water purifier body 2 having a substantially cylindrical shape, the purifying part 4 formed in a substantially cylindrical shape having an axis that overlaps with the water purifier body 2, and the outer diameter, The water purifier body 2 and a substantially cylindrical switching operation part (switching operation means) 40 in which the outer diameter is substantially the same as that of the water purification unit 4 and the axis and the rotation center axis R overlap are arranged in series to provide purified water. Container 1 is configured. That is, the purification unit 4, the water purifier main body 2, and the switching operation unit 40 are symmetric with respect to the central section S. The center of the inlet 7 provided in the case body 5 of the water purifier body 2, the center of the raw water discharge port 9, the center of the water purification discharge port 12, and the center of the shower discharge port 10 are on the central section S. Has been placed. In addition, the dot 20 described in the first embodiment is provided on the upper outer peripheral surface of the switching operation unit 40, and on the other hand, the outer peripheral surface of the case body 5 closest to the switching operation unit 40 is provided with A display unit 41 is provided along the outer peripheral surface, and the characters “raw water”, “shower”, and “Shimizu” along the front-rear direction are written horizontally. And this These display units 41 are arranged at intervals corresponding to the rotation angle Θ of the switching operation unit 40 set at the same angle on both the front and rear sides. In FIG. 17, the faucet 3 is omitted for convenience of illustration.

Therefore, according to the third embodiment, there is no difference in operability even if the arrangement of the switching operation unit 40 is switched between the left and right sides. Further, as in the first and second embodiments, the purification is not performed. Compared with the case where the longitudinal direction of the part 4 is arranged along the vertical direction, the outer peripheral surface of the purification unit 4 and the outer peripheral surface of the water purifier body 2 are continuous, so that the design can be improved.

Note that, for example, as shown in FIG. 18, the switching operation portion (switching operation means) 42 is connected to a semi-ring-shaped member 43a along the vertical direction and the front-rear direction as shown in FIG. For example, when the switching operation part 42 is configured so as to be slightly deviated from the left and right positions as viewed from the user, the semi-ring-shaped member 43b is formed so as to be orthogonal to the rotation center axis R of the switching operation part 42. Even if they are arranged, switching by the switching operation unit 42 can be performed only by pinching and rotating the portions where the half ring-shaped members 43a and 43b are orthogonal to each other, which is advantageous in terms of operability.

[0060] Next, a fourth embodiment of the present invention will be described with reference to Figs. Since the fourth embodiment relates to the inside of the case body 5 of the water purifier 1 of the first embodiment described above, the same part is incorporated with the aid of FIG. 1 of the first embodiment. The same reference numerals are assigned and duplicate descriptions are omitted.

[0061] As shown in FIG. 20, a receiving port (raw water receiving port) 7 for receiving tap water, which is raw water, is formed from the faucet 3 at the approximate center of the upper casing 5a of the water purifier 1. It is attached to the discharge port 3b of the faucet 3 via a ring-shaped mounting jig 8. A passage 45 communicates with the lower side of the receiving port 7, and the passage 45 is connected to the primary side of the rotary valve 46 having a rotation shaft along the longitudinal direction of the water purifier body 2. The rotary valve 46 switches a plurality of flow paths, and the valve position of the rotary valve 46 is switched to a desired position by operating a switching operation unit 17 that can rotate in the front-rear direction in association with the rotation shaft. I am able to do that.

On the other hand, on the secondary side of the rotary valve 46, a raw water discharge port 47, a shower discharge port 48, and a raw water supply port 49 are arranged. These raw water discharge port 47, shower discharge port One of the port 48 and the raw water supply port 49 selectively communicates with the passage 45 on the primary side according to the valve position of the rotary valve 46. In addition, the raw water discharge port 47 communicates with the raw water discharge port 9 provided on the coaxial extension of the receiving port 7 described above, and the shower discharge port 48 discharges the raw water from the receiving port 7 in the form of a shower. Around the raw water discharge port 9, a shower discharge port 10, which is a large number of holes arranged in an annular shape, communicates. The raw water supply port 49 constitutes a flow path for supplying raw water to the water purification cartridge 4.

Here, the raw water discharge port 9 and the shower discharge port 10 are formed in the same substantially disk-shaped member, and the raw water discharge port 9 is arranged at the center. This substantially disk-shaped member is detachably attached to the lower part of the rotary valve 46, and passes through the lower casing 5b described above and faces downward. In addition to the substantially disc-shaped member having the raw water discharge port 9 and the shower discharge port 10 penetrating the lower casing 5b, for example, the substantially disc-shaped member having the raw water discharge port 9 and the shower discharge port 10 is used. The member may be formed integrally with the lower casing 5b. In this case, the hole of the discharge port 10 may be provided simultaneously with the molding of the lower casing 5b or after the molding of the lower casing 5b. . Further, the case where the raw water discharge port 9 and the shower discharge port 10 are fitted to each other as a structure for attaching the raw water discharge port 10 to the rotary valve 46 has been described. However, for example, a screwed structure may be used as long as it is detachable.

[0064] The water purifier main body 2 includes a base portion 11 that detachably supports the entire lower portion of the water purification cartridge 4 with a downward force. In this base portion 11, the opposite side force of the switching operation portion 17 provided in the water purifier main body 2 is also formed to extend along the longitudinal direction of the water purifier main body 2. The base 11 has a lower surface covered from a side surface thereof by a casing 20 formed integrally with the lower casing 5b.

[0065] Incidentally, as shown in Figs. 20 and 21, the rotary valve 46 has an axis line arranged in the left-right direction on the central section S (see Figs. 5 and 6) of the first embodiment described above. A valve body 50 having a substantially bottomed cylindrical shape is provided, and a rotary shaft 51 that protrudes outward along the axis is formed at one end of the valve body 50. The valve body 50 is housed in a substantially cylindrical valve body housing portion 52 provided inside the case body 5 and is rotatably supported. In addition, the rotary shaft 51 of the valve body 50 is fitted into a hole 53 formed at the tip of the rotary shaft 16 of the switching operation portion 17 to be inserted. 54 is fixed. That is, the axis of the valve body 50 is arranged on an extension line of the axis of the switching operation unit 17 so that the rotation direction of the rotary valve 46 matches the rotation of the switching operation unit 17.

[0066] On the other hand, the above-described raw water discharge port 47, shower discharge port 48, and raw water supply port 49 are formed below the rotary valve 46, that is, below the valve body housing 52, respectively, and the valve Arranged along the axial direction of the body 50. Further, above the valve body 50, a passage 45 leading to the raw water receiving port 7 is formed in an upward direction directly above the raw water discharge port 47, and this passage 45 communicates with the inside of the valve body housing 52. Yes.

[0067] The lower wall portion 50a of the valve body 50 of the rotary valve 46 corresponds to the raw water discharge port 47, the shower discharge port 48, or the raw water supply port 49 according to the operation position of the switching operation portion 17. A raw water discharge hole 54, a shower discharge hole 55, and a raw water supply hole 56 communicating with any one of the ports are formed for each port. More specifically, when the valve position force S selected by the switching operation portion 17 is “raw water”, a raw water discharge hole 54 is formed in the lower wall portion 50a at a position facing the raw water discharge port 47, and similarly, When the valve position is “shower”, a shower discharge hole 55 is formed in the lower wall portion 50a at a position facing the discharge port 48 of the shutter. A raw water supply hole 56 is formed in the lower wall portion 50a facing the raw water supply port 49 when the valve position is “clean water”.

That is, the raw water discharge hole 54, the shower discharge hole 55, and the raw water supply hole 56 are separated at predetermined rotation angles of the valve body 50 according to the turning operation of the switching operation unit 17. Are arranged on the lower wall portion 50a, and are further arranged on the lower wall portion 50a at predetermined intervals according to the arrangement of the raw water discharge port 47, the shower discharge port 48, and the raw water supply port 49 along the axial direction of the valve body 50. Is placed.

On the other hand, all the valves described above with respect to the opening of the passage 45 formed in the upper wall portion 50b of the valve body 50 along the circumferential direction of the valve body 50 and communicating with the raw water receiving port 7 are provided. A long hole 57 is formed so as to face each other. The long hole 57 allows the passage 45 and the internal space of the valve body 50 to communicate with each other regardless of the displacement of the valve position caused by the turning operation of the switching operation portion 17. At this time, the tip of the passage 45 is located inside the valve body. More precisely, the flow path is controlled. Specifically, when raw water flows at a high flow velocity, the raw water leaks to the outside of the valve body. It is preferable from the viewpoint of prevention. In this case, the size of the long hole 57 is designed so that the tip of the passage 45 can always pass through the long hole 57 regardless of the displacement of the valve position caused by the turning operation of the switching operation portion 17. The

Further, a seal member 60 is provided between the lower wall portion 50a of the valve body 50 and the raw water discharge port 47, the shower discharge port 48, and the raw water supply port 49. The seal member 60 constitutes the rotary valve 46 together with the valve body 50 described above, and includes a main plate portion 60a formed in a substantially strip shape having a predetermined thickness for ensuring sufficient strength. Further, the main plate portion 60a of the seal member 60 is formed with holes 61, 62, 63 at positions corresponding to the raw water discharge port 47, the shower discharge port 48, and the raw water supply port 49, respectively.

[0071] Further, ring-shaped convex portions 64 projecting toward the valve body 50 are formed integrally with the main plate portion 60a at the peripheral edges of the holes 61, 62, 63, and the seal member 60 is attached to the valve body. In a state where it is attached to the lower part of the accommodating part 52 (see FIG. 20), the convex part 64 presses the periphery of the holes 54, 55, 56 of the lower wall part 50a, Watertightness is maintained.

Then, as shown in FIG. 21, a groove 70 for inserting the seal member 60 along the axis of the valve body 50 is formed in the lower portion of the valve body housing portion 52. The upper edge portion is provided with a locking portion 71 that protrudes inward from the groove 70. On the other hand, the edge portion 65 on the long side of the seal member 60 described above is stepped and formed corresponding to the locking portion 71. Accordingly, by slidingly inserting the seal member 60 along the groove 70 from one end side, the stepped edge 65 of the seal member 60 is locked by the locking portion 71, and the displacement of the seal member 60 is restricted. The

That is, according to the rotary valve 46 described above, as shown in FIG. 22A, when “raw water” is selected by the switching operation unit 17, the raw water received from the receiving port 7 passes through the long hole 57 from the passage 45. Through the valve body 50, and further through the raw water discharge hole 54 formed in the lower wall portion 50a of the valve body 50, the hole 63 of the seal member 60, and the raw water discharge port 47. Outlet 9 Forced to discharge downward.

Further, as shown in FIG. 22B, when “shower” is selected in the switching operation unit 17, the raw water received from the receiving port 7 enters the valve body 50 from the passage 45 through the long hole 57. Further, it flows through the shower discharge hole 55 formed in the lower wall portion 50a of the valve body 50, the hole 62 of the seal member 60, and the shower discharge port 48, and is directed downward from the shower discharge port 10. Discharge in the form of a char.

Then, as shown in FIG. 22C, when “shower” is selected in the switching operation unit 17, the raw water that has received the force of the receiving port 7 flows down from the passage 45 into the valve body 50 through the long hole 57. The raw water flows into the purification unit 4 through the raw water supply hole 56 formed in the lower wall part 50a of the valve body 50, the hole 61 of the seal member 60 and the raw water supply port 49, and the water purification cartridge 13 After being purified, the purified water is discharged from the purified water discharge port 12 with a downward force.

Therefore, according to the above-described fourth embodiment, the valve body 50 is rotated along the circumferential direction of the rotary shaft 16 in conjunction with the switching operation unit 17, and the raw water discharge port 47, the shower discharge Since the communication state between the port 48 and the raw water supply port 49 and the passage 45 is switched, a symmetrical shape can be maintained with respect to the central cross section of the case body 5 in the front-rear direction.

In addition, since the valve body 50 is formed in a substantially cylindrical shape, for example, in the conventional rotary valve, the passage is individually formed inside the valve body, resulting in a complicated shape or a plurality of There is a problem that the number of parts increases due to the combination of parts, but the rotary valve can be configured with a simple shape and the assembly becomes easy, so the burden of assembly work can be reduced. At the same time, an increase in cost can be suppressed.

[0077] Further, by providing the raw water discharge port 47, the shower discharge port 48, and the raw water supply port 49 all downward, the position of the raw water supply port for supplying the raw water to the water purification cartridge 13 is not on the side of the water purification unit. Since it can be provided below, the height position of the water purification unit 4 can be suppressed, and the degree of freedom in design can be improved.

In addition, since the axis of the substantially cylindrical valve body 50 is arranged along the longitudinal direction of the case body 5, it is possible to suppress the size of the case body 5 in the front-rear direction, further improving design flexibility. Can be achieved.

[0078] Furthermore, by providing a seal member 60 between the lower wall portion 50a and the raw water discharge port 47, the shower discharge port 48, and the raw water supply port 49, the raw water discharge port 47, the shower discharge port 48, and the raw water are provided. Watertightness between any one of the supply ports 49 and the valve body 50 can be maintained, and the seal member 60 is integrally formed in a band shape, so that each port is sealed individually. Compared with the case where the member 60 is attached, the burden of the attachment work can be reduced. [0079] In the above-described fourth embodiment, the force described in the case where the valve body 50 of the rotary valve 46 is formed in a substantially cylindrical shape is displaced along a rotation axis that is not limited to this. For example, it may be a semi-cylindrical shape in the lower half as long as it has a wall portion. Industrial applicability

[0080] According to the present invention, the same operability can be secured on either the left or right side of the switching operation means. In addition, since the number of parts can be reduced compared to the case where a switching operation means is provided on both the left and right sides as in the case of a conventional water purifier, the water purifier can be reduced in size. Since the switching operation means is not arranged at the position that blocks the view below the raw water discharge port and the purified water discharge port as in the case of the vessel, it is possible to prevent deterioration in workability due to the blockage of the view and to be usable. .
