Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a remote-controlled drain cock that closes and opens a bottom drain port of a wash basin or the like by a predetermined operation of an operation piece provided at a position remote from the stopper.
[0002]
[Prior art]
As a drain plug for a wash basin, a sink, a bathtub, and the like (hereinafter, referred to as a wash basin, etc.), for example, a so-called remote control type in which a bottom drain port is opened and closed by an operation piece provided on a peripheral upper surface of the wash basin or the like. Things are known.
[0003]
For example, as disclosed in Japanese Utility Model Laid-Open No. 06-046068 and Japanese Utility Model Laid-Open No. 06-020564, in such a remotely operated drain plug, a plug that closes a bottom drain port of a wash basin or the like is provided with an operating piece. A push-pull, pull-up knob, for example, via an interlocking member composed of a combination of each rod integrated with the stopper and a lever rod rotatable in a seesaw shape, or an interlocking member formed of a flexible wire. It is connected so as to be able to interlock with the operation piece of the shape. This type of remote operation is performed such that the bottom body drain port such as a wash basin is opened (opened) and closed (closed) by raising and lowering the plug in conjunction with a predetermined operation of the operation piece by pushing and lifting. A drainage tap is constructed.
[0004]
[Problems to be solved by the invention]
By the way, in the above-mentioned remote-operated drainage tap, water used in a wash basin or the like is drained through a bottom drain port generated by the rise of the plug and a gap between the plugs. In other words, since the drainage space from which water flows out tends to be relatively narrow, it is not easy to secure the smooth drainage of a large amount of water, etc., which is stored under the closed bottom drainage port. A decline is inevitable.
[0005]
Here, in order to secure a large drainage space at the bottom drainage port, for example, it is conceivable to raise the plug higher to widen the gap between the bottom drainage port and the plug. However, in the remote-operated drain plug, since the interlocking member is usually interposed in the drain channel from the bottom drain port, a reduction in the effective sectional area itself of the bottom drain port cannot be avoided.
[0006]
Therefore, if the gap between the bottom drainage port and the plug is simply widened, the drainage speed cannot be easily increased.
[0007]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a remote-operated drainage plug that can reduce drainage time by ensuring smooth outflow of water or the like during drainage.
[0008]
[Means for Solving the Problems]
In order to achieve this object, according to the present invention, a large amount of water or the like accumulated in a wash basin or the like by closing the bottom drain port flows out from the opened bottom drain port as a spiral flow in a specific direction. We pay attention to.
[0009]
Therefore, according to the present invention, on a flat cross section, the end on the outer peripheral side with respect to the base end defined as the terminal on the shaft portion side is a straight line connecting the base end and the center of the plug body on a plane. From the extension, a plurality of spiral wall-like projections twisted along the rotation direction of the spiral flow, defined as a position shifted by a specific distance in a direction opposite to the rotation direction of the spiral flow generated at the time of drainage, A shaft body with a sealed part that can be tightly attached to the bottom drain port periphery so that a spiral drain flow path twisted in the corresponding direction can be formed in the drain space, which is a gap between the bottom drain port and the plug. At least around the lower surface of the plug within the surrounding area .
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0011]
As shown in FIG. 1, in a remote-operated drain plug 10 according to the present invention, a plug 16 capable of closing a bottom drain port 14 of a wash basin 12 and the like, and a plug body such as an upper peripheral edge 12a of a wash basin or the like. The operation piece 18 disposed at a position remote from the user is connected by an interlocking member 20 so as to enable remote operation of the plug with the operation piece. The remote-controlled drain plug 10 is configured so that the bottom drain port 14 can be opened and closed by raising and lowering the plug 16 by the operation piece 18.
[0012]
The plug 16 is, for example, formed into a substantially T-shaped vertical cross-section integrally having a rod-shaped shaft 22 extending downward, and by inserting the shaft into the inside of a pipe 24 serving as a drainage channel, The plug is disposed so as to be able to close the opening of the pipe that serves as the bottom drainage port 14. Reference numeral 26 denotes a spacer provided integrally with the shaft portion 22. When the spacer slides on the tube (drainage passage) 24, the shaft, that is, the plug 16 is turned into a tube, and thus a bottom portion. The center of the drain 14 is supported so that it can move up and down smoothly.
[0013]
In addition, in such a plug 16, the peripheral edge 16 a is formed as a sealing portion that is in close contact with the peripheral edge of the bottom drainage port 14.
[0014]
As can be seen from FIG. 1, the operation piece 18 is provided integrally with the upper end of the support rod 28, for example, and is supported by a holder 30 provided on the upper peripheral edge 12a of the water tank so as to be able to move up and down.
[0015]
The shaft 22 of the plug and the support rod 28 of the operation piece are, for example, so-called universal joints 34 and 35 at the respective ends of the lever rod 32 having a rotation support point 32a formed of a sphere at an intermediate position. And are rotatably and non-detachably connected via the.
[0016]
That is, in the embodiment of the present invention, the support rod 28 of the operation piece and the lever rod 32 which can rotate in a seesaw shape around the rotation fulcrum 32a and which can be interlocked with the shaft body portion 22 of the plug body . The combination is embodied as an interlocking member 20 that connects the plug 16 and the operation piece 18 in an interlockable manner.
[0017]
According to the remote-operated drainage plug 10 using this kind of interlocking member 20, the plug body is pushed up by the lever rod 32 when the operating piece 18 is pushed in as shown by a solid line in FIG. The bottom 16 is lifted from the bottom drain port 14, and the raised portion separates the sealing portion (peripheral edge) 16a of the plug from the opening end of the bottom drain port, so that the bottom drain port is opened, that is, opened.
[0018]
When the operation piece 18 is pulled up in the direction of the arrow from the pushing position indicated by the solid line in FIG. 1, the seesaw-like rotation of the lever rod 32 about the rotation fulcrum 32 a causes the plug 16 to move together with the shaft body 22. When pulled down, the bottom drain port 14 is closed, or closed, as shown by the two-dot chain line in FIG.
[0019]
The basic structure and operating principle of the remote-operated drain plug 10 are known, for example, as disclosed in Japanese Utility Model Laid-Open No. 06-046068, and the structure itself is not the purpose of the present invention. Detailed description is omitted.
[0020]
By the way, in this type of remote-operated drain plug 10, the gap formed between the plug and the bottom drain port 14 due to the rise of the plug 16 becomes a drain space in the wash basin 12 or the like. In the case of a large amount of water or the like stored under the closure of the bottom drain port, the drainage speed from the bottom drain port tends to decrease.
[0021]
Here, in the present invention, attention is paid to the fact that a large amount of water or the like accumulated in the wash basin 12 by closing the bottom drain port 14 flows out from the opened bottom drain port as a spiral flow in a specific direction. ing. Therefore, as shown in FIGS. 1 and 2, in the present invention, a spiral wall-shaped projection 38 extending in the rotation direction of a spiral flow generated at the time of drainage is vertically provided integrally on the lower surface of the plug 16. are doing.
[0022]
As shown in FIGS. 2 and 3, the wall-like projections 38 are provided at a plurality of locations separated by an equal angle, for example, three locations separated by 120 °.
[0023]
As can be clearly seen from FIG. 3, the flat cross-sectional shape of the wall-shaped projection 38 is such that the terminal on the flat cross-section located on the peripheral surface of the shaft portion 22 is the base end 38a, and the base end and the plug It is formed by setting its end 38b at a position shifted by a specific distance L1 in a certain direction from a linear extension line 40 connecting the center O of the body 16 on a plane .
[0024]
Here, in the northern hemisphere of the earth including Japan, the swirl flow at the time of drainage is usually clockwise when the bottom drainage port 14 is viewed from above, so when used in Japan, As shown in FIG. 3, for example, the end 38a of the wall-shaped projection is shifted from the extension line 40 in a counterclockwise direction viewed from above, as shown in FIG. Is set.
[0025]
Here, as the specific distance L1 from the extension line 40, for example, a distance corresponding to a position separated from the center O 2 of the plug 16 by about 60 ° can be exemplified.
[0026]
The wall-shaped projection 38 is provided in a range where the sealing portion is left on the peripheral edge so as not to hinder the plugging due to the close contact of the sealing portion 16a with the peripheral edge of the bottom drainage port 14; As shown in FIG. 7, for example, the plane cross section between the base end 38a and the end 38b is formed in an arc shape.
[0027]
Such a wall-shaped projection 38 has a so-called spiral shape that is inclined by a distance L2 along the rotation direction (clockwise viewed from above) of the spiral flow so as not to hinder the flow of water or the like as the spiral flow. Is formed.
[0028]
In such a configuration, since the wall-like projection 38 on the lower surface of the plug is vertically provided in the direction along the rotation direction of the spiral flow generated at the time of drainage as shown by a two-dot chain line in FIG. A spiral opening corresponding to the flow direction of the water or the like flowing in the shape is obtained between the adjacent wall-shaped protrusions in the drainage space serving as a gap between the bottom drainage port 14 and the plug 16. By adjusting the direction of the opening of the drainage space between the bottom drainage port 14 and the plug 16 to the rotating direction of the spiral flow generated at the time of drainage, the outflow of water or the like while rotating spirally can be easily performed. Because it can be secured, drainage from the drainage space between the bottom drainage port and the plug is performed quickly.
[0029]
Therefore, even when draining a large amount of water or the like accumulated by closing the bottom drain port 14, the water drains out of the drain space between the bottom drain port and the plug 16 becomes smooth, and the drainage speed is increased. , Drainage time is reduced.
[0030]
It is sufficient that the wall-like projections 38 are spirally provided at about three places on the lower surface of the plug 16, so that the remote-operated drain plug 10 that can reduce the drainage time without complicating the configuration is easily provided. Can be secured.
[0031]
In the configuration having the wall-shaped projection 38 on the lower surface, the pressure at the time of drainage causes the plug 16 to rotate in the corresponding direction, that is, in the clockwise direction when viewed from above. In the configuration of the embodiment, since the lower end of the shaft body portion 22 integrated with the stopper is connected to one end of the lever rod 32 via the universal joint 34, the connection portion is prevented from rotating, and when draining, No rotation of the plug occurs.
[0032]
Here, in the embodiment of the present invention, the plane cross section between the base end 38a and the end 38b of the wall-like projection 38 is formed in an arc shape . However, the wall-shaped projection 38 can have a flat cross-sectional shape connecting the base end 38a located on the peripheral surface of the shaft body portion 22 and the end 38b located at a position shifted by a distance L1 counterclockwise from the extension line 40. For the sake of suffice, the shape is not limited to the arc-shaped flat cross-sectional shape as shown in FIG. 3. For example, the wall-shaped projection may be formed as having a linear flat cross-sectional shape as shown in FIG. 4.
[0033]
Even in such a wall-shaped projection 38 having a straight cross-sectional shape between the base end 38a and the end 38b , the twisted direction of the wall-shaped projection is spiral because the wall-shaped projection is spiral. A spiral opening corresponding to the flow direction of water flowing in a spiral shape, which coincides with the rotation direction of the flow, is obtained in the drain space between the bottom drain port 14 and the plug 16 in the same manner as described above. . Therefore, also in this configuration, the same effect that the speed at the time of draining a large amount of water accumulated by closing the bottom drain port is increased and the drain time is shortened is obtained.
[0034]
Further, in the embodiment of the present invention, the wall-shaped projections 38 are embodied as being provided at three places. However, the wall-shaped projections have spiral openings corresponding to the flow direction of water or the like flowing in a spiral shape. The number of wall-shaped projections is not limited to this, as long as it can be formed between adjacent wall-shaped projections. For example, the wall-shaped projections may be provided at two or four or more locations.
[0035]
However, in the two wall-shaped projections 38, it is inevitable that the functionality as an opening in accordance with the flow direction of water or the like is reduced, and conversely, if the number of wall-shaped projections is large, the wall-shaped projections may cause drainage. Since there is a possibility of obstruction, a spiral opening of an appropriate direction can be ensured, and about three places which do not obstruct drainage are preferable as the number of wall-shaped projections.
[0036]
Here, in the embodiment of the present invention, the wall-shaped projection 38 can be suspended in accordance with the direction of the clockwise spiral flow when the bottom drainage port 14 is viewed from above, and the end 38b of the wall-shaped projection is Are set in a counterclockwise direction as viewed from above from a linear extension line 40 connecting the center O of the plug 16 and the base end 38a on a plane .
[0037]
However, conversely, the end 38b of the wall-shaped projection is shifted clockwise as viewed from above from a linear extension line 40 connecting the center O of the plug 16 and the base end 38a on a plane. If set, a spiral opening oriented in accordance with the counterclockwise spiral flow when the bottom drain port 14 is viewed from above is obtained in the drain space between the bottom drain port and the plug 16, so that drainage In this case, a remotely operated drain plug 10 usable in an area where a counterclockwise spiral flow is generated, that is, in the southern hemisphere of the earth or the like, can be easily secured.
[0038]
By the way, in the embodiment of the present invention, the plug 16 is formed integrally with the shaft portion 22, and is arranged so as not to rotate with respect to the flow of water or the like. However, the present invention is not limited to this. For example, the stopper may be rotatable under a flow of water or the like.
[0039]
As shown in FIG. 5, in this configuration, the plug 116 is formed separately from the shaft portion 122, and the loosely-fitted connection end 122a of the upper end of the shaft portion is fitted into the bearing hole 42 of the plug. By such means, it is rotatably connected to the shaft body.
[0040]
Incidentally, in this case, the proximal end 138a of the wall-like protrusions 138 lower surface of the shaped spiral provided vertically integrated in the plug body 116, is formed separately from the linked shaft portion 122 of the plug 116 I have . The end 138b of the wall-like projection is a linear extension connecting the base end 138a and the center O of the plug on a plane within a range in which the sealing portion 116a is left on the peripheral edge, similarly to the above-described embodiment. It is set at a position shifted from the line in a certain direction.
[0041]
In such a configuration, a spiral-shaped opening corresponding to the flow direction of water or the like flowing in a spiral shape, a bottom drain opening 14, because resulting in drainage space between the plug body 116, while rotating in a spiral shape The outflow of water and the like can be easily secured, and the drainage time is shortened by increasing the drainage speed.
[0042]
Then, according to this configuration, the plug 116 rotates in the corresponding direction when the wall-shaped projection 138 receives the pressure when draining water or the like from the bottom drain port 14. In other words, water and the like drained from the bottom drain port 14 smoothly flow out without receiving the resistance force of the wall-shaped projections 138 of the plug, so that a higher drainage speed can be secured.
[0043]
Therefore, by making the plug 116 rotatable, the drainage time of the remotely operated drain plug 10 can be further reduced.
[0044]
Further, in the embodiment of the present invention, the support rod 28 of the operation piece and the lever rod that can be linked with the shaft body portion 22 (122) of the stopper, which is rotated in a seesaw shape around the rotation fulcrum 32a. combination of 32, the plug 16 (116), are illustrated as interlocking member 20 interlocked coupled between operating pieces 18, interlocking between the shaft body portion having a plug body and operating piece 18 member It is sufficient that the connection is possible so as to be interlocked, and the present invention is not limited to the interlocking member of the above combination. For example, as disclosed in Japanese Utility Model Laid-Open Publication No. May be applied.
[0045]
Further, in this embodiment, a configuration in which the plug 16 (116) is moved up and down by pushing and pulling up the operation piece 18 is exemplified, but the invention is not limited thereto, and is disclosed in, for example, Japanese Utility Model Publication No. 06-031259. The remote-operated drain plug 10 of the present invention can also be applied to a configuration in which opening and closing of the bottom drain port is switched by the plug under repeated pressing of the operation piece.
[0046]
The remote-operated drain tap of the present invention is suitable as a drain tap for a wash basin, but is not limited thereto. For example, the present invention is applied to a drain tap such as a sink, a bathtub, and another installed water tank. May be applied.
[0047]
The above-described embodiments of the present invention are intended to explain the present invention, and do not limit the present invention in any way. All modifications and alterations within the technical scope of the present invention are also included in the present invention. It goes without saying that it is included in.
[0048]
【The invention's effect】
As described above, according to the remote-operated drain plug according to the present invention, the spiral opening corresponding to the flow direction of water or the like flowing in a spiral , the bottom drain port, in the drain space between the plugs, Since it is obtained between adjacent wall-shaped projections, outflow of water or the like as a spiral flow can be easily secured. Therefore, even when a large amount of water or the like accumulated by closing the bottom drain port is drained, the drainage speed of the water or the like from the drain space between the bottom drain port and the plug is increased, and the drain time is shortened.
[0049]
Then, it is sufficient if vertical set integrally with the lower surface of the plug a corresponding direction wall-shaped projections inclined in a spiral shape, without complicating the structure, easily remote controlled discharge valve which is shorter drainage time Can be secured.
[0050]
In addition, by displacing the end of the wall-like projection in a counterclockwise direction viewed from above from the extension of a straight line connecting the base end and the center of the plug on the plane, the northern hemisphere of the earth including Japan A remote-operated drain plug suitable for use in the world can be obtained, and the same drain plug suitable for use in the southern hemisphere etc. of the earth can be obtained by shifting the end of the wall-shaped projection clockwise as viewed from above. can get.
[0051]
Therefore, a remote-operated drainage plug suitable for the northern and southern hemispheres of the earth can be easily secured by simply changing the direction in which the end of the wall-shaped projection is set without complicating the configuration.
[0052]
If the stopper is rotatable with respect to the shaft portion, the water and the like drained from the bottom drain port smoothly flow out without receiving the resistance force due to the wall-shaped projections of the stopper, so that the speed is faster. Drainage speed can be secured. Therefore, the drainage time of the remotely operated drain plug can be further reduced.
