Description

  The present invention relates to a cylinder type valve device.

A cylinder valve body rotatable around an axis in conjunction with the operation of the switching handle and having a hot water supply passage therein, and a valve case having a cylindrical portion for accommodating the cylinder valve body so as to be fitted therein. , A cylinder type valve device configured as a main element is widely used. In a general cylinder type valve device, a valve case is provided with a first opening on the valve case side communicating with the shower hose and a second opening on the valve case side communicating with the callan. Furthermore, the cylinder valve body is provided with a cylinder valve body-side first opening and a cylinder valve body-side second opening corresponding to these openings, respectively. In such a general cylinder type valve device, the first opening of the valve case side and the first opening of the cylinder valve body side are changed according to the relative rotation position of the cylinder valve body with respect to the valve case accompanying the operation of the switching handle. When the positions substantially coincide with each other, a flow path communicating with the shower hose flows from the hot water supply flow path in the cylinder valve body, and hot water is supplied to the shower hose. When the position of the valve case side second opening substantially coincides with the position of the cylinder valve body side second opening, the hot water supply flow path in the cylinder valve communicates with the flow path communicating with the curan, and water is discharged from the curan.
As such a cylinder-type valve device, a technique for reducing the wear of a portion that transmits rotation to a cylinder valve body has also been proposed (for example, see Patent Document 1).

The switching handle 22 switches between water discharge from the water discharge unit 23 and water discharge from the shower-side water discharge unit 24 by rotating operation, and adjusts the flow rate of water discharge from each water discharge unit.
Further, the temperature adjustment handle 25 adjusts the temperature of the discharged water by a rotating operation.

Next, the cylinder type valve device 100 will be described in detail with reference to FIG. 3, FIG. 4, and FIG.
FIG. 3 is a partially cutaway sectional view showing the faucet apparatus of FIG. 1 including a section of a cylinder type valve apparatus.
FIG. 4 is a perspective view of a cylinder type valve device as one embodiment of the present invention.
FIG. 5 is a view showing a cylinder valve body and an outer cylinder member in a valve case of the cylinder type valve device of FIG.

The cylinder-type valve device 100 causes the hot water whose temperature has been adjusted by the temperature adjusting device 200 (FIG. 2) to be discharged from the curan-side water discharging unit 23 or from the shower-side water discharging unit 24 in conjunction with the rotation operation of the switching handle 22. Switching whether to discharge water is performed and the amount of hot water is adjusted.
The illustrated cylinder type valve device 100 is a cylindrical body that extends in the axial direction, is connected to the switching handle 22, and is rotatable around an axis in conjunction with the operation of the switching handle 22. There is provided an outer cylinder member 160 that accommodates the inner cylinder 110 so as to be fitted therein, and a valve case 150 that accommodates the cylinder valve body 110 and the outer cylinder member 160 therein. The cylinder valve body 110 and the outer cylinder member 160 can rotate integrally with the valve case 150, and the outer cylinder member 160 can be said to be a part of the cylinder valve body 110.

A hot water supply flow path 111 is formed concentrically inside the cylinder valve body 110, and a cylinder valve body side opening 120 penetrating the hot water supply flow path 111 is provided on a peripheral surface thereof.
Further, the cylinder valve body 110 is provided with a drive shaft portion 112 that extends coaxially inside the switching handle 22 from an end on the switching handle 22 side, which is the end side of the hot water supply flow path 111. A serration portion 112a that fits with a fitted portion formed inside the switching handle 22 is formed near the distal end of the drive shaft portion 112.
The outer cylinder member 160 is provided with a cylinder valve body side opening 161 at a position corresponding to the cylinder valve body side opening 120. As shown in FIG. 5, the cylinder valve body-side opening 161 includes two similar openings 161a and 161b arranged in the axial direction. The cylinder valve body-side opening 161 adjusts the flow rate of the cylinder valve body-side opening 120, which has a large spread in the circumferential direction, to the valve case-side openings 151 and 152.
The valve case 150 has a plurality of (two in this example) valve case-side openings having the same axial position and being circumferentially separated so as to correspond to the cylinder valve body-side openings 120 and 161. Of these two openings in the present example, one of the two openings, the valve case-side first opening 151, is a callan-side opening that communicates with the callan-side water discharge section 23 through the flow path 2300. The other opening 152 on the valve case side, which is the other opening, is a shower-side opening communicating with the shower-side water discharging section 24 through the flow path 2400. In addition, the flow path 2300 leading to the water discharge part 23 on the callan side in FIG. 3 is mostly turned downward (in the depth direction of the drawing) from the cross section in FIG. 3 to a portion (reference numeral 2300) shown by a two-dot chain line in FIG. I understand.

Referring to FIG. 4, a seal member 171 is provided at an edge of the curan-side opening 151 so that the shape is maintained by an appropriate frame member or the like. The seal member 171 is a seal member similar to an O-ring, and is a packing that prevents leakage of flowing water (hot water) around the opening.
Similarly, the sealing member 172 is provided at the edge of the shower-side opening 152 so that the shape is maintained by an appropriate frame member or the like. The seal member 172 is also a seal member similar to the O-ring, and is a packing that prevents leakage of flowing water (hot water) around the opening.

Next, the manner in which the flow path is switched in the cylinder type valve device 100 of the present embodiment will be described with reference to the sectional views of FIGS. That is, the hot water flow path is closed, the hot water flow path is formed from the curan side, and the hot water flow path is formed from the shower side in response to the turning operation of the switching handle 22. Will be described with reference to the above drawings.
FIG. 6 is a sectional view taken along line AA when the cylinder type valve device of FIG. 3 is in a closed state.
FIG. 7 is a cross-sectional view taken along the line AA when the callan side is selected in the cylinder type valve device of FIG.
FIG. 8 is a sectional view taken along the line AA when the shower side is selected in the cylinder type valve device of FIG.
6, 7, and 8 are drawn in a view in which the switching handle 22 side is viewed from the cylinder valve body 110 side.
The switching handle 22 shown by a two-dot chain line in FIGS. 6, 7, and 8 is connected to the cylinder valve body 110 by the drive shaft 112 described above. Accordingly, the cylinder valve element 110 rotates in response to the rotation operation on the switching handle 22, and the positions of the cylinder valve body-side openings 120 and 161 move in the circumferential direction along with the rotation.
As can be easily understood from FIGS. 6, 7, and 8, in this example, the direction from the axis of the cylinder valve body 110 to the center of the curan side opening 151 and the shower from the axis of the cylinder valve body 110 The direction toward the center of the side opening 152 is orthogonal. That is, the callan-side opening 151 and the shower-side opening 152 have the same position in the axial direction, and are 90 degrees apart from each other at an inferior angle in the circumferential direction.

  In the state of FIG. 6, the switching handle 22 shown by the two-dot chain line is in a rotating position in which the operation end side is downward. At this time, as shown in the figure, the cylinder valve body-side opening 161 does not form a communication path with the hot water supply flow path 111 with either the curan-side opening 151 or the shower-side opening 152. Therefore, in this state, the faucet device 1 is in the valve closed state.

  In the state of FIG. 7, the switching handle 22 shown by the two-dot chain line is in a substantially horizontal rotation position. At this time, as shown in the drawing, the cylinder valve body-side opening 161 communicates with the callan-side opening 151, and no communication path is formed with the shower-side opening 152. That is, the hot water supply flow path 111 communicates with the curan side opening 151. In this state, the water faucet device 1 discharges the water (hot water) supplied through the hot water supply flow path 111 from the callan-side water discharging section 23.

  In the state of FIG. 8, the switching handle 22 shown by the two-dot chain line is in a rotating position in which the operation end side is upward. At this time, as shown in the drawing, the cylinder valve body-side opening 161 does not communicate with the callan-side opening 151, and a communication path is formed with the shower-side opening 152. That is, the hot water supply flow path 111 communicates with the shower-side opening 152. In this state, the faucet device 1 discharges the water (hot water) supplied through the hot water supply flow path 111 from the shower-side water discharge unit 24.

As can be easily understood with reference to FIGS. 6, 7 and 8 described above, in the cylinder type valve device 100 of the present embodiment, the turning position in which the end of the switching handle 22 is downward (see FIG. 6), the faucet device 1 is in the valve-closed state, and when the switching handle 22 is turned from this position to a horizontal rotation position (the position in FIG. 7), water is discharged from the callan. When the turn 22 is turned to a turning position (the position in FIG. 8) in which the end portion is directed upward, a state in which water is discharged from the shower is set.
Therefore, by gradually raising the operation handle 22 by a predetermined angle, switching in the order of closing → calling water discharging → shower-water discharging, and switching from shower to water discharging such as closing → shower-water discharging in principle does not occur. For this reason, the inconvenience of inadvertently pouring cold water from the shower without the opportunity to notice this before the hot water temperature rises is also avoided in principle.
Further, since the circumferential width of the cylinder valve body-side opening 161 is wider than the interval between the curran side opening 151 and the shower side opening 152, the cylinder valve body side opening 161 is located on the curan side in a certain rotation angle range of the cylinder valve body 110. Both the opening 151 and the shower-side opening 152 are provided so as to overlap. When the switching handle 22 is rotated, the hot water supply flow path 111 in the cylinder valve body 110 is moved into the cylinder valve body side openings 120 and 161 in the above-described certain rotation angle range (or an angle range corresponding thereto). Through both the callan-side opening 151 and the shower-side opening 152 to discharge water from both the callan and the shower. When the switching handle 22 is rotated upward beyond the range of the rotation angle, the water discharge from the callan side is closed and the water is discharged from the shower side.

Next, a cylinder type valve device 100a which is a modified example of the cylinder type valve device 100 described with reference to FIGS. 1 to 8 will be described with reference to FIGS.
9 is a diagram showing a modification of the cylinder type valve device of FIG. 4, and FIG. 10 is a cross-sectional view of the cylinder type valve device of FIG.
The difference between the cylinder type valve device 100a shown in FIGS. 9 and 10 and the cylinder type valve device 100 described above is that the cylinder type valve device 100 has a direction from the axis of the cylinder valve body 110 toward the center of the curan side opening 151. And the direction from the axis of the cylinder valve body 110 toward the center of the shower-side opening 152 is 90 degrees, whereas the angle θ is 120 degrees in the cylinder-type valve device 100a. .
That is, in the cylinder-type valve device 100a, the callan-side opening 151a and the shower-side opening 152a in the valve case 150a have the same axial position and are circumferentially spaced apart by 120 degrees at an inferior angle.
In FIG. 10, the switching handle 22 shown by a two-dot chain line is in a rotation position in which the operation end side faces downward. At this time, as shown in the drawing, neither the callan-side opening 151a nor the shower-side opening 152a of the cylinder valve body-side opening 161 forms a communication path with the hot water supply flow path 111. Therefore, in this state, the faucet device 1 is in the valve closed state.
In the present modification, the distance between the curran side opening 151a and the shower side opening 152a is wider than the circumferential width of the cylinder valve body side opening 161. Therefore, the cylinder valve body-side opening 161 does not overlap with both the callan-side opening 151a and the shower-side opening 152a, and water can be stopped at an intermediate position.

Next, a cylinder type valve device as another embodiment (second embodiment) of the present invention will be described with reference to FIGS.

Furthermore, the water faucet side discharge part 23 is connected to the lower part of the faucet main body 2b, and the shower side water discharge part 24 is connected to the back side of the faucet main body 2b. The water discharge part 23 and the water discharge part 24 on the shower side of the cylinder type valve device 100b are respectively formed by the corresponding flow paths 2300 and 2400 connected to the inside of the faucet main body 2 (curan side opening and shower side opening). It is connected to the.

The switching handle 22 and the temperature adjustment handle 25 are rotatable in a predetermined direction with respect to the faucet main body 2b.
The switching handle 22 switches between water discharge from the water discharge unit 23 and water discharge from the shower-side water discharge unit 24 by rotating operation, and adjusts the flow rate of water discharge from each water discharge unit.

And a curan-side opening 251 and a shower-side opening 252 are provided so as to be separated from each other in the circumferential direction. The callan-side opening 251 and the shower-side opening 252 in the valve case 150b are aligned with the callan-side opening 181b and the shower-side opening 182b in the outer shell 301 described above.
The curan-side opening 251 includes two similar openings 251a and 251b arranged in the axial direction. Similarly, the shower side opening 252 includes two similar openings 252a and 252b arranged in the axial direction.

Referring to FIG. 14 and FIG. 15, a seal member 271 is provided at an edge of the callan-side opening 251 of the valve case 150b so that the shape is maintained by an appropriate frame member or the like. The seal member 271 is a seal member similar to an O-ring, and is a packing that prevents leakage of flowing water (hot water) around the opening.
Similarly, a sealing member 272 is provided at the edge of the shower-side opening 252 of the valve case 150b so that the shape is maintained by an appropriate frame member or the like. This seal member 272 is also a seal member similar to the O-ring, and is a packing that prevents leakage of flowing water (hot water) around the opening.

The cylinder valve body 110b in FIG. 16 has the same position in the axial direction on the peripheral surface of the cylinder valve body 110b, corresponding to the above-described curan-side opening 251 and shower-side opening 252 in the valve case 150b, and The first opening 221 on the cylinder valve body side and the second opening 222 on the cylinder valve body side are provided so as to be separated from each other in the circumferential direction.

According to the above-described embodiment, the following operation and effect can be obtained.
(1) A cylinder valve body 110 rotatable around an axis and having a hot water supply passage 111 therein, and a valve case 150 accommodating the cylinder valve body 110 therein. And the valve case 150 has a plurality of axially spaced and circumferentially spaced apart valve casings 150 corresponding to the cylinder valve body openings 120 and 161. The valve case side openings 151 and 152 are provided.
The plurality of valve case-side openings 151 and 152 are connected to, for example, the callan-side water discharge unit 23 and the shower-side water discharge unit 24, and selectively (at the switching intermediate position, water is simultaneously supplied to the callan side and the shower side). Water supply (hot water supply) can be performed (including the case), but the plurality of valve case-side openings 151 and 152 are provided at the same axial position. For this reason, the length in the axial direction can be shortened as compared with a general cylinder type valve device, and as a result, the material cost is reduced, and as a result, a cylinder type valve device with low manufacturing cost can be provided.
In particular, as shown in FIG. 5, if a configuration is adopted in which the cylinder valve body-side openings 120 and 161 provided in the cylinder valve body 110 are provided at one place in the circumferential direction, the processing cost is reduced as compared with the case where the cylinder valve body-side openings are provided at a plurality of places. Can be reduced, and the manufacturing cost can be further reduced.

(2) In the cylinder type valve device 100, in particular, the plurality of valve case side openings 151 and 152 are configured to communicate with different flow paths of the faucet main body having the cylinder type valve device.
For this reason, it is possible to supply water (hot water supply) to different flow paths of the faucet body.

(3) In the cylinder type valve device 100, in particular, the plurality of valve case-side openings are a callan-side opening 151 communicating with a curan and a shower-side opening 152 communicating with a shower hose, and the curran-side opening 151 and the shower-side opening 152 are cylinder-shaped. When the cylinder valve body 110 rotates counterclockwise in a position where the operation handle 22 is viewed from the valve body 110 side, at a predetermined initial position of rotation, the cylinder valve body side openings 120 and 161 are closed by the valve case side openings 151 and 161. 152, the cylinder valve body-side openings 120 and 161 communicate with the callan-side opening 151 at a position separated from the initial position by a predetermined first rotation angle range, and the second rotation angle range exceeds the first rotation angle range. The cylinder valve body-side openings 120 and 161 communicate with the shower-side opening 152 at positions spaced apart from each other by an angular range. Mouth 120,161, Curran side opening 151 and the relative position of the shower side opening 152 is set.
For this reason, the initial position is set to a position where the operation handle 22 faces downward, and the operation handle 22 is gradually raised from the position by a predetermined angle, so that the switching is performed in a manner such as closing → water discharge → shower water discharge, a so-called up operation water discharge method. Can be adopted. Therefore, when an object accidentally falls and hits the operation handle 22, the water is switched to the closing side instead of the water discharging side, so that unintended water discharging occurs and water (hot water) is wasted. Such disadvantages can be avoided in principle.
Further, in the cylinder type valve device 100, the operation handle 22 is gradually raised by a predetermined angle to switch the state from closing to draining water to shower water, but switching in one step such as closing to shower and water discharging does not occur in principle.

(4) In the cylinder type valve device 100, particularly, seal members 171 and 172 that seal around the valve case side openings 151 and 152 are provided in the valve case 150. Therefore, the plurality of valve case-side openings 151 and 152 are individually sealed around the openings. Therefore, the running water or hot water inside does not leak to the outside from each of the plurality of valve case-side openings 151 and 152, and furthermore, the problem that the leaked running water or hot water is mixed is avoided.

(5) In addition, in the switching of callan water discharge → shower water discharge, there is an operation angle of the operation handle 22 in which the hot water supply passage 111 inside the cylinder valve body 110 communicates with any of the callan side opening 151 and the shower side opening 152. .
For this reason, the inconvenience of inadvertently pouring cold water from the shower without the opportunity to notice this before the hot water temperature rises is also avoided in principle.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications and changes within the scope of achieving the object of the present invention are included in the present invention.
For example, in the first embodiment and the second embodiment described above, the valve case side opening is two (two places) corresponding to the callan side and the opening corresponding to the shower side. The aperture can be increased to allow for a wide variety of switching.
In addition, various modifications and changes that do not depart from the gist of the present invention are included in the present invention.
