Description

Remote operation type drainage plug device

Technical Field

The invention belongs to the technical field of drainage equipment, and particularly relates to a remote operation type drainage plug device which can control the opening and closing of a valve arranged on a water tank.

Background

The prior remote-operated drain plug device is composed of a valve component for controlling the drain outlet at the bottom of a water tank, an operating component for controlling the lifting of the valve component, a release wire for connecting the operating component and the valve component, and a locking mechanism for keeping the lifting state of the valve component. A gasket is embedded around the valve member and is tightly engaged with the rim of the drain opening when the valve member is closed, thereby allowing water to be stored in the water tank. The operating component is provided with a switch for a user to touch and control, and the switch is arranged on the upper surface or the side surface or the wall panel surface of the water tank. The user can achieve the effect of preventing the water outlet of the water tank from being controlled to be opened and closed by directly contacting with the valve part through the operation of the switch. The release wire is composed of a resin cylindrical outer tube and a corrugated inner wire, and the inner wire is pushed into the outer tube by pressing the switch, so that the valve component is pushed up to control the opening and closing of the water outlet. The locking mechanism is internally provided with a rotating gear and a fixed gear, and the valve component is kept in a rising or falling state through the meshing of the rotating gear and the fixed gear.

However, since the switch of the remote-operated drain cock device is installed on a side surface or a wall surface of the sink, there are problems as follows:

when the water tank is a bathtub, the back of the bathtub is the inner wall surface of a bathroom; when the sink is a kitchen sink or washbasin, the back of the sink or washbasin is the inside surface of the cabinet; that is, only a narrow space exists on the back surface of the water tank. Therefore, the release wire connected to the tip of the switch is especially twisted to be installed in the narrow space toward the valve member at the drain port. Thus, the inner wire that releases the wrinkle of the wire may be too short in bendable radius, which may cause poor operation or breakage.

In order to solve the above problems, japanese patent application laid-open No. 2005-1133331 provides a remote-operated drain plug device, which is installed inside a water tank through a locking mechanism, so that a bendable radius of a release wire is increased, thereby preventing the occurrence of poor operation or breakage due to an excessively short bending radius. However, since the locking mechanism of the remote-operated drain plug device disclosed in this patent document is mounted on the inside of the sink, the opening and closing member and the locking mechanism protrude on the inside surface of the sink, resulting in poor appearance of the sink. Also, when the sink is a tub, the sides of the sink may contact the back of the bather, which can affect the comfort of the bather if the switch member is particularly protruding. Further, the release wire is still disposed in a narrow space, and the occurrence of defective operation or breakage cannot be completely prevented.

In addition, patent document No. 2014-167251 provides a remote operation type drain plug device in which a switch member is pushed up and down, and at the same time, a tip of a release wire is installed in an up-and-down direction, whereby the release wire can be disposed without being bent, and thus, a phenomenon of poor operation or breakage due to an excessively short bending radius is not generated. However, since the locking mechanism of the remotely operated drain plug device disclosed in this patent document is provided in the drain passage, the drainage in the drain port is obstructed by the locking mechanism, resulting in a decrease in the drain flow rate. Even if the lock mechanism is provided at the tip on the side of releasing the wire switch, the flow rate of the drain water in the overflow path is also lowered by the lock mechanism. Further, if the latch mechanism is provided at the tip of the side where the wire switch is released, it is difficult to remove the latch mechanism from the drain port of the overflow path due to the gear provided in the latch mechanism, which complicates the maintenance work of the drain plug device.

Detailed Description

The structure of the remotely operated drain plug device according to the present invention will be described below with reference to the accompanying drawings. The following description is only for the convenience of understanding the embodiment, and should not be construed as limiting the invention. In the following embodiments, positional relationships between the upper, lower, left, right, and the same members will be described with reference to the direction of the construction state of the remotely operated drain plug device shown in fig. 1 as much as possible.

Example 1

As shown in fig. 1 to 10, the remote-operated drain cock device of the present invention comprises a drain cock 1 installed in a sink B, a valve member 18, a release wire 20, and an operating member 30 installed on a side surface of the sink.

In this embodiment, the water tank B is a tank body of a box structure with an open top, and both the bottom and the side surfaces thereof are provided with circular openings. When the drain cock device of the remote-controlled type according to the present invention is installed in the sink B, the drain cock 1 is installed in the opening of the bottom of the sink B, and the operating member 30 is installed at the opening of the inner side surface of the sink B.

Specifically, the drain plug 1 is a tubular structure, the periphery of the upper end of the drain plug protrudes outwards and extends to form a jaw part, a drain port 2 for draining water in the water tank B is arranged in the drain plug, a convex part is formed in the drain plug, a metal wire connecting part 15 is arranged on the convex part, and male threads are arranged on the periphery of the tubular part at the lower end of the drain plug 1. A claw portion is provided on the periphery of the wire connecting portion 15 and engages with the convex portion via the claw portion, and a bearing portion 16 for attaching one end of the release wire 20 is provided on the wire connecting portion 15.

When the drainage bolt 1 is installed in the opening at the bottom of the water tank B, the cylindrical part at the lower end of the drainage bolt 1 is inserted into the opening formed at the bottom of the water tank B and is connected with the drainer 5 below the opening at the bottom of the water tank B, namely, the female thread arranged on the inner ring at the upstream side of the drainer 5 is in threaded connection with the male thread on the periphery of the cylindrical part at the lower end of the drainage bolt 1, so that screwing is realized. In normal use, a drain opening 7 is provided on the downstream side of the drain 5 to allow water flowing into the drain 5 to further flow into a downstream drain pipe (not shown). In order to mount the operation member 30 of the present invention, a branch pipe 6 is provided at a side of the drain 5, and the branch pipe 6 is connected to the operation member 30 through an overflow pipe 10 having a disturbance property.

Specifically, the valve member 18 is a lid-like member having a gasket fitted on its outer peripheral surface, and as shown in fig. 1, when the valve member 18 is in a lowered state, the gasket on the valve member 18 abuts against the drain plug 1 to close the drain port 2 of the drain plug 1. In addition, the bottom end surface of the valve member 18 is engaged with the top end of the release wire 20, and when the valve member 18 is pushed by the release wire 20, it rises to open the drain port 2.

Specifically, the release wire 20 is a motion transmission member mainly composed of an outer tube 21 and an inner wire 22, and one end of the release wire 20 is provided with a wire spool 23 provided in the operating member 30, the wire spool 23 is connected to one end of the inner wire 22, the other end of the release wire 20 is provided with a valve shaft 26 provided in the drain opening 2 and connected to the bearing portion 16, and the valve shaft 26 is connected to the other end of the inner wire.

Further, the outer tube 21 is a hollow resin tubular member having a resistance property in a side surface direction of the water tank B, and the inner wire 22 having a movable wrinkle having a resistance property in a side surface direction is attached to the inside thereof.

Further, the metal spool 23 is a metal core connected to one end of the inner wire 22, and is disposed in the operating part 30 through a support cylinder 24. Specifically, the metal bobbin 23 is disposed in a support cylinder 24, and the upper end thereof is connected to an operation member 30, and it can move up and down in the support cylinder 24, and the up and down movement is a vertical up and down movement, as explained with reference to the direction of fig. 1.

In this embodiment, the support cylinder 24 is a hard resin cylindrical structure, the lower end of which is connected to one end of the outer tube 21, and the wire spool 23, the inner wire 22 and a spring 25 are installed therein. Among them, the portions of the metal bobbin 23 and the inner metal wire 22, which are inserted into the operation part 30, are disposed up and down, the central axes of the metal bobbin 23 and the support tube 24 are disposed up and down, and the lower end portion of the metal bobbin 23 is inserted into the interior of the support tube 24 located therebelow. The lower end of the spring 25 is connected to an inner jaw formed inside the lower end of the support cylinder 24, and the upper end thereof is connected to the lower end of the wire spool 23, and is completely installed in the support cylinder 24 and sleeved on the periphery of the portion of the inner wire 22 extending into the support cylinder 24.

Further, the valve shaft 26 is a cylindrical structure provided at one end portion of the drain port 2 located in the inner wire 22 of the release wire 20, engages with the bottom end surface of the valve member 18, and is constituted by an outer cylinder 27 and an inner cylinder 28. The outer cylinder 27 is a hollow cylindrical body connected to the outer tube 21, and the outer side surface thereof engages with the bearing portion 16 of the wire connecting portion 15. The inner cylinder 28 is disposed in the outer cylinder 27, and the inner cylinder 28 is a cylinder connected to the inner wire 22, is movable in the vertical direction inside the outer cylinder 27, and is provided with a damper spring inside. The top end of the inner cylinder 28 is nested with the bottom end face of the valve member 18 and moves up and down with the inner wire 22 within the outer tube 21, but the inner cylinder 28 extends from the outer tube 27, causing the valve member 18 to rise. When the inner cylinder 28 is in the raised protruding state, an impact force is applied to the upper side of the valve shaft 26, but the impact force is absorbed by the damper spring, thereby preventing the breakage of the components.

As shown in fig. 1 to 6, specifically, the operating part 30 mainly includes an overflow elbow 31, a switch 35, a locking mechanism 40, and an auxiliary part 50; and the operation member 30 is attached to an opening on the inner side surface of the wall of the sink B in use.

As shown in fig. 2 to 3, the bent overflow pipe 31 is an L-shaped drain pipe having a pipe bent at about 90 degrees, and has a flange portion protruding outward at the outer periphery of the top end portion on the upstream side, and the bent overflow pipe 31 has an inlet 32 at one end facing the lateral direction (left side in fig. 2) and an outlet 33 at the downstream side. A plurality of protrusions engaged with the locking mechanism 40 are provided on the inner wall of the inlet 32 of the overflow trap 31, a substantially circular fixing member 34 having a notch is provided on the inner wall of the outlet 33 of the overflow trap 31, and the fixing member 34 is attached to the support tube 24 of the release wire 20. In this embodiment, the fixing member 34 has an approximately U-shape, and has an inner diameter almost identical to that of the support cylinder 24. In the present embodiment, the support of the support cylinder 24 is realized by the fixing member 34 of the overflow bend 31.

Further, as shown in fig. 3, 4a and 4B, the switch 35 partially protrudes toward the inside of the water tank B to form a protrusion; the locking mechanism 40 is provided on the protruding portion, and the switch 35 has a pushing portion 36, a supporting portion 37, and a connecting portion 38. When operated by a user, the switch 35 can move up and down along the vertical direction at the opening of the inner side surface of the wall of the water tank B.

The pushing portion 36 is composed of an upper panel and a side panel protruding from the inside of the water tank B, and the pushing portion 36 has an L-shaped cross-sectional structure and a locking mechanism 40 is provided therein. The lower portion of the pushing portion 36 is open, and water in the water tank B can flow into the inlet 32. As shown in fig. 4a, the pushing portion 36 is rectangular in front view, and is disposed between the guide portions 52 of the auxiliary member 50, and when the valve member 18 is in a lowered state (closed state), the upper end and the lower end of the pushing portion 36 are respectively positioned on a plane with the upper end and the lower end of the adjacent guide portion 52.

The support portion 37 extends from the inside (rightward in fig. 2) of the pushing portion 36 toward the inside of the overflow trap 31, and has a connecting portion 38 at the end. The connecting portion 38 has an L-shaped cross-section, is connected to the top end of the metal bobbin 23, and transmits the operation received by the pushing portion 36 to the metal bobbin 23.

As described above, the pushing portion 36 contacts the locking mechanism 40, and the connecting portion 38 contacts the release wire 20, so that when the switch 35 is lowered by the pressing operation, the release wire 20 and the locking mechanism 40 are moved together.

Further, as shown in fig. 2 and 3, the locking mechanism 40 is a holding mechanism of a pressure lock mechanism, which includes a sleeve. The inner wall of the sleeve of the locking mechanism 40 is provided with a fixed thread, and the center of the sleeve is provided with a locking shaft 41 with a rotating thread.

The lock shaft 41 partially passes through and protrudes above the sleeve, extends to the inner side of the pushing portion 36, and can move up and down in the sleeve. Wherein the rotating thread is rotatable but not movable up and down with respect to the lock shaft 41. When the lock shaft 41 is lowered, the lock mechanism 40 can maintain the lowered state of the lock shaft 41 by screwing the rotary screw and the fixed screw.

The locking mechanism 40 is disposed in the switch 35, and the upper end of the lock shaft 41 abuts against the inner side of the pushing portion 36. Also, the axial direction of the lock shaft 41 is disposed in the vertical direction, so that the axial direction of the lock shaft 41 is almost parallel to the moving direction of the switch 35 and the axial direction of the tip of the release wire 20. However, since the lock mechanism 40 is attached to the inside of the wall of the water tub B, the center axis of the lock shaft 41 is set at a position different from the center axis of the end of the release wire 20 on the side of the operating member 30.

Therefore, the axial directions of the wire spool 23, the support cylinder 24, the release wire 20, and the end portion on the side of the operation portion 30 of the present invention are almost the same direction as the moving direction of the switch 35.

As shown in fig. 5, the locking mechanism 40 further includes an annular portion 42 disposed outside the sleeve. The annular portion 42 has an outer diameter substantially equal to the inflow port 32, and is fixed to the inside of the overflow trap 31 by being connected to a convex portion in the overflow trap 31 by a claw portion.

Further, as shown in fig. 6a and 6b, a notch 51 is formed below the auxiliary member 50, and the notch 51 has a U-shape in plan view, and guide portions 52 having a substantially rectangular configuration in plan view are provided at both ends of the notch 51.

Therefore, as shown in fig. 2 and 4, the auxiliary member 50 is fixed between the side wall of the water tub B and the flange portion of the bent spill pipe 31 by inserting the notch 51 into the outside of the flange portion of the bent spill pipe 31 with the long side of the guide portion 52 facing in the vertical direction.

The remote-operated drain plug device of the present invention is constructed as follows, but in the following construction flow, the description of the drain pipe on the downstream side of the drainer 5 is omitted:

first, after the drain plug 1 and the drain 5 are mounted on the opening of the bottom of the sink B, the overflow trap 31 is mounted on the opening of the side of the sink B in a state where the notch 51 of the auxiliary member 50 is inserted, and then the overflow pipe 10 is connected to the branch pipe 6 of the drain 5 and the outflow port 33 of the overflow trap 31. Thus, a drain passage for water flowing in from the drain port 2 and a spill passage for water flowing in from the inlet port 32 are formed. An attaching position guide mechanism, not shown, is provided on the outer surface of the flange portion of the overflow bent pipe 31, and the long side of the guide portion 52 is provided in the vertical direction.

Next, as shown in fig. 7, the valve shaft 26 of the release wire 20 is inserted into the overflow trap 31 through the inflow port 32, and the support cylinder 24 of the release wire 20 is attached to the fixing portion 34. Thus, the release wire 20 is guided by the overflow pipe 10, and the valve shaft 26 is connected to the inside of the drain 5 through the branch pipe 6. The valve shaft 26 is removed from the water tank B in the drain port 2, and after the valve shaft 26 is fixed to the wire support portion 15, the claw portion of the wire support portion 15 is screwed and fixed to the convex portion of the drain plug 1.

Thereafter, as shown in fig. 8, the locking mechanism 40 is inserted into the inlet 32 and fixed in the overflow trap 31, and then, as shown in fig. 9, the switch 35 is attached to the inlet 32. At this time, the switch 35 is fixed between the auxiliary member 50 and the guide portion 52 and can move only in the vertical direction, the tip of the wire bobbin 23 is in contact with the connection portion 38, and the operation of the switch 35 can be transmitted to the wire bobbin 23.

Finally, the valve member 18 is engaged with the valve shaft 26, thereby completing the process.

The remote-operated drain cock device of the present invention can be operated by detaching the locking mechanism 40 from the overflow bend 31 by removing the switch 35 when the maintenance work of the locking mechanism 40 is performed. Further, if maintenance of the release wire 20 is desired, after the locking mechanism 40 is removed, the wire support portion 15 is removed from the drain plug 1, the wire support portion 15 and the valve shaft 26 are removed, the support tube 24 is removed from the fixing portion 34, and then the release wire 20 is drawn out from the inlet 32 for maintenance. In the present invention, the release wire 20 and the locking mechanism 40 are not directly connected, and only the locking mechanism may be separately removed for maintenance.

The operation and water flow of the remote-operated drain cock device of the present invention will be described as follows:

first, as shown in fig. 1, when the valve member 18 is in a descending state, the gasket nested around the valve member 18 is tightly engaged with the upper surface of the drain cock 1, and at this time, the water tank B can store water.

When the valve member 18 is in the lowered state, the user presses the top surface of the pushing portion 36 of the switch 35, thereby pressing the connecting portion 38 and the wire bobbin 23 through the support portion 37. Since the inner wire 22 is connected to the wire bobbin 23, the inner cylinder 28 protrudes from the outer cylinder 27 to move toward the valve member 18 from the inside of the outer cylinder 21 in accordance with the downward movement of the wire bobbin 23 under pressure, thereby raising the valve member 18. At this time, as shown in fig. 10, the lock shaft 41 is also lowered in accordance with the depression of the pushing portion 36, and the lock shaft 41 is lowered, and the rotary screw is turned to be screwed with the fixing screw, thereby holding the valve member 18 in the raised state. As shown in fig. 4b, when the valve member 18 is in the raised state, the pushing portion 36 is located below the guide portion 52 adjacent thereto in plan view, and the user can grasp the state of the valve member 18 by looking at the switch 35.

In the case where the valve member 18 is in the raised state, if the user presses the upper surface of the pushing portion 36 of the switch 35 again, the supporting portion 37, the connecting portion 38, the wire spool 23, and the portion of the inner wire 22 located at the operating member 30 are also lowered, so that the portion of the inner wire 22 located at the valve member 18 is lifted up to bring the valve member 18 to slightly rise. At this time, as the lock shaft 41 is lowered again, the rotary screw is turned, and the engagement with the fixing screw is released. As a result, the pushing operation of the pushing portion 36 is completed, the valve member 18 is lowered by its own weight and the elasticity of the spring 25, and the pushing portion 36 is restored to the same plane at its upper and lower ends as those of the adjacent guide portions 52 as shown in fig. 4 a. At this point, the gasket nested around the valve member 18 is again in close contact with the upper surface of the drain plug 1 and the drain port 2 is closed.

As above, when the valve member 18 is in the raised state, the water stored in the sink B flows into the drain plug 1 through the drain port 2 and further flows to a drain pipe (not shown) further below through the drain 5.

Conversely, when valve member 18 is in the lowered position, water may be stored in reservoir B. When the accumulated water in the tank B exceeds the lower end of the inlet 32, the accumulated water flows into the inlet 32 and the overflow bent pipe 31 through the lower end of the pushing portion 36, further flows into the branch pipe 6 through the overflow pipe 10, flows into the drain 5, and finally flows into the drain pipe located further below and is discharged. In the present invention, the lock mechanism 40 is not provided in the overflow path, so that the amount of water discharged from the overflow path is not reduced.

The remote-operated drain cock device of the present invention can easily perform maintenance work because the locking mechanism 40 is installed inside the wall of the sink B, and can prevent the drainage of the overflow path from being lowered because the locking mechanism 40 is not installed in the overflow path. In the present invention, since the release wire 20 and the locking mechanism 40 are provided independently of each other and are not directly connected to each other, it is possible to simply remove the locking mechanism 40 and perform maintenance.

Further, since the axial direction of the lock shaft 41 and the moving direction of the switch 35 are both vertical and are positioned approximately parallel to each other, even if the lock mechanism 40 of the present invention is installed in the water tub B, the portion of the operation portion 30 protruding into the water tub B becomes short. In addition, in the present invention, since the axial direction of the end of the release wire 20 on the side of the operation portion 30 is vertical, the release wire does not have to be bent, and thus, it is possible to prevent the occurrence of an operation failure, a component damage, or the like.

The above is the first embodiment of the present invention, and the present invention is not limited to the first embodiment, and various shapes may be changed within a range not exceeding the gist of the present invention. In the other embodiments described below, like parts are denoted by the same reference numerals as in the first embodiment unless otherwise specified, and the description thereof is omitted.

Example 2

The structure of the present embodiment 2 is substantially the same as that of the embodiment 1, and the differences are only that: in example 1, the inner wire 22 is a crimped wire that is relatively well tensioned but relatively poorly stressed in compression. In the present embodiment 2, to solve the above problem, as shown in fig. 11 and 12, the pressing operation linkage system may be configured as follows: when the switch is pressed, the release wire 20 is pulled to the operation portion 30 side.

In the present embodiment, the rotation member 60 is provided in the overflow trap 31, and the connection portion 38 of the switch 35 and the wire bobbin 23 have threads that engage with the rotation member 60.

When the pushing portion 36 is pushed down, the connecting portion 38 raises the wire spool 23 by the rotating member 60, thereby pulling the inner wire 22.

Therefore, as shown in fig. 11, when the lock shaft 41 is in the lowered state, the valve member 18 is also in the lowered state, and the drain port 2 is closed. As shown in fig. 12, when the lock shaft 41 is in the raised state, the valve member 18 is also in the raised state, and the drain port 2 is opened. In contrast, in embodiment 1, the pushing portion 36 is almost flush with the upper and lower surfaces of the adjacent guide portion 52 when the valve member 18 is in the lowered state, whereas in embodiment 2, the pushing portion 36 is almost flush with the upper and lower surfaces of the adjacent guide portion 52 when the valve member 18 is in the raised state.

Therefore, in the present embodiment 2, the pressing action can be prevented from being directly applied to the compression direction with respect to the inner wire 22. Therefore, it is possible to avoid the force being applied instantaneously at the time of the pressing operation, and it is possible to further prevent the breakage of the inner wire 22.

Example 3

In embodiment 1 and embodiment 2, the upper and lower ends of the pushing portion 36 are almost flush with the adjacent guide portions 52 when the lock shaft 41 is in the raised state, and the upper and lower ends of the pushing portion 36 may be almost flush with the adjacent guide portions 52 when the lock shaft 41 is in the lowered state. That is, in embodiment 1 and embodiment 2, although the pushing portion 36 protrudes downward with respect to the adjacent guide portion 52, the pushing portion 36 may protrude upward with respect to the adjacent guide portion 52 when the lock shaft 41 is in the raised state.

That is, in embodiment 1, the overflow trap is formed of one member and is connected to the outer wall of the tub B by a nut, and embodiment 3 is different from embodiment 1 only in that: as shown in fig. 13, the overflow trap 31 is formed of two parts. At this time, the overflow trap 31 of the present embodiment 3 can be screwed from the inside of the sink B, which is advantageous for facilitating the installation of the overflow trap 31.

Example 4

In each of the above embodiments, the lock mechanism 40 is configured such that the sleeve is fixed to the inflow port 32 and the lock shaft 41 is pressed, but in embodiment 4, as shown in fig. 14, the lock shaft 41 is fixed to the inflow port 32 and the sleeve is changed to the pressed structure.

In addition, in other modified embodiments, the switch 35 may be moved in the vertical up-down direction instead of the left-right direction in each of the above embodiments. In this case, the lock shaft 41 is provided in the left-right direction, and a structure for preventing the apparatus from being enlarged can be adopted.

The end of the release wire 22 on the side of the operation portion 30 may be arranged in the horizontal direction. At this time, the space outside the water tub B increases in the horizontal direction, and the release wire 20 may be bent. Here, the left-right direction is a left-right direction indicated in fig. 4, which is different from the left-right direction shown in fig. 2. That is, the switch 35 and the auxiliary member 50 may be rotated by 90 degrees as shown in fig. 4, and the switch 35 may be moved in the left-right direction. In this case, it is preferable that the lock mechanism 40 and the metal shaft 23 are also rotated by 90 degrees in accordance with the moving direction of the switch 35.

In the above embodiments, the water tank has the overflow flow path, but the water tank to which the present invention is applied is not limited to this water tank. The invention is also applicable to kitchen sinks or washbasins.

In the remote-operated drain cock device of the present invention, the locking mechanism 40 is provided inside the water tank B, and the axial direction of the locking shaft 41 is the same as the moving direction of the switch 35, so that the maintenance work can be easily performed, and the portion of the operating member 30 protruding to the inside of the water tank B is also shortened. Since there is no direct connection between the release wire 20 and the locking mechanism 40, it is possible to simply remove the locking mechanism 40 alone for maintenance.

Compared with the prior art, the remote operation type drain cock device can prevent the release metal wire from poor operation and damage, and can easily realize the maintenance and the repair of the drain cock device.

The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
