Description

Water leakage sensing water pipe for water purifier and water pipe cut-off system having the same}

According to the present invention, when the first signal line and the second signal line installed between the inner water supply hose and the outer corrugated pipe are shorted to each other by the leaked water, an electrical closed circuit is formed to detect the leak and automatically close the valve. It relates to a pipe and a pipe leakage blocking system for a water purifier including the same.

In general, a water purifier is also called a cold and hot water purifier, receives tap water supplied from a branch pipe, purifies through a filter, and provides the user with cold water or hot water by using a cold / hot system provided therein.

A water supply hose is used to supply water to such a water purifier. The water supply hose connects water from the branch pipe to the water purifier, and supplies water to the water purifier at branch pipes installed in homes as well as in multi-use facilities or offices (restaurants, coffee shops, etc.).

Therefore, when a leak occurs in the water supply hose, water resource waste occurs due to the leak of water, and water leaks into the room. Furthermore, when external contaminants enter the water supply hose, the water supplied to the water purifier is contaminated.

In particular, when the distance between the sink in the kitchen where the branch pipe is installed and the specific location in the hall where the water purifier is installed is long, the length of the water supply hose is also relatively long, and it is often hidden and installed along the floor duct or ceiling. .

Therefore, as the length increases, the possibility of water leakage in each part of the water supply hose increases, but it is difficult to detect it at an early stage, and there is a problem that the water supply cannot be automatically stopped while the damage is very large.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the water leak detection pipe for water purifiers and pipe water leakage blocking system for water purifiers including the same.

First, as shown in FIG. 1, the water leakage blocking system for water purifiers according to the present invention is installed between the inlet pipe (IP) for supplying tap water and the water purifier (WP) is installed in a remote water supply, water leak detection for water purifier The pipe 10 includes a DC power supply device 20 and a magnetic valve 30.

At this time, the leak detection pipe 10 for the water purifier of the present invention connects the inlet pipe (IP) and the water purifier (WP), and supplies the tap water introduced through the inlet pipe (IP) to the water purifier (WP). For example, the entry pipe (IP) is provided in a sink (SI) installed in a home or a multi-use facility (restaurant, coffee shop, etc.).

When the inlet pipe (IP) is installed inside the sink in the case of a three-way branch pipe, the inlet side (Pi) of the lower part is connected to the external water pipe, the first outlet side (Po-1) of the upper part is connected to the faucet of the sink The second discharge side Po-2 of the side part is connected to the magnetic valve 30 of the present invention.

Accordingly, water is supplied to the faucet (faucet) of the sink Si through the first discharge side Po-1 of the inlet pipe IP, and in the case of the second discharge side Po-2, it is normally (leakage). In the normal state without this), water is supplied to the water purifier WP through the magnetic valve 30 in the open state.

On the other hand, if water leaks while supplying water to the water purifier WP through the water leak detection pipe 10 for the water purifier, the DC power supply device 20 (as shown in FIG. 5) is formed as described below. : Power of the battery) is applied to the magnetic valve 30 to be in a closed state (water supply interruption), and the water supply to the water purifier WP is stopped.

That is, as will be described later, the present invention uses water leaked from the signal lines 13-1 and 13-2 provided between the water supply hose 11 and the corrugated pipe 12 constituting the water leak detection pipe 10 for a water purifier. When shorted with each other, an electrical closed circuit is formed to generate a valve shutoff signal. In addition, the valve 30 is blocked by the valve shutoff signal.

Therefore, when a leak occurs in the water supply hose 11 connecting the inlet pipe (IP) and the water purifier (WP), it is quickly detected, and the water purifier (through the hose where the leak occurs by closing the valve 30 by the leak occurrence signal) Automatically cut off water supply to WP).

To this end, as shown in FIG. 2, the leak detection pipe 10 for the water purifier according to the present invention includes a water supply hose 11, a corrugated pipe 12, a first signal line 13-1, and a second signal line 13-2. ). Preferably, the apparatus further includes a double-sided adhesive tape 14 for easily attaching the first signal line 13-1 and the second signal line 13-2 to the inner wall of the corrugated pipe 12.

At this time, the water supply hose 11 is for supplying water to the water purifier WP installed remotely from the inlet pipe (IP), the water flows along the inner hollow, one end is connected to the inlet pipe (IP) , The other end is connected to the water supply port of the water purifier (WP).

More specifically, one end of the water supply hose 11 is connected to the second discharge side (Po-2) of the inlet pipe (IP) through the magnetic valve 30, the other end is a water bottle provided in the water purifier (WP) body By being connected to, the water introduced through the inlet pipe (IP) is supplied to the water purifier (WP).

The corrugated pipe 12 protects the water supply hose 11 from the external environment. Especially in multi-use facilities (e.g. for commercial use), corrugated pipes with water supply hoses 11, which are easily damaged as they extend to water purifiers (WPs) installed at relatively long distances through ducts (brackets) or ceilings on floors or walls. Protect with (12).

To this end, the water supply hose 11 is fitted to the inner hollow portion of the corrugated pipe 12, and as the annular corrugations are continuously provided (continuously formed in a spiral direction) along the tubular body, the water supply hose 11 is formed in a direction away from the inner center to the outside. And a trough 12a.

The valley 12a provided in the corrugated pipe 12 refers to a space portion in which the first signal line 13-1 and the second signal line 13-2, which will be described later, may be installed on the inner surface of the corrugated pipe 12. Therefore, the part protruding convexly outward with respect to the hollow axis of the corrugated pipe 12 is defined as the valley 12a.

However, the corrugated pipe 12 may be formed in a groove shape having a round cross section as shown in FIG. 2, but as the bottom surface of the valley 12a '12a' 'is flat as shown in FIG. 3, its width is relatively wide. Accordingly, the first signal line 13-1 and the second signal line 13-2 may be easily installed.

In addition, as shown in (b) of FIG. 3, the corrugated pipe 12 having a shape in which the inclined surfaces of the left and right (based on the drawings) are symmetrical with respect to the bottom surface of the valley 12a ', as shown in FIG. 12a ''), the corrugated pipe 12 having a shape in which the left and right (referenced) inclined surfaces are asymmetrical to each other may also be applied.

The symmetric corrugated tube 12 as shown in FIG. 3A allows the first signal line 13-1 and the second signal line 13-2 to be stably seated at the center of the valley 12a. On the other hand, the asymmetric corrugated pipe 12 as shown in (b) of FIG. 3 has a first signal line 13-1 and a second signal line inserted into the valley 12a in the helical direction along the valley 12a '' during the manufacturing process. 13-2) can be retracted more easily, such as sliding through one side of a relatively inclined slope.

The first signal line 13-1 is continuously disposed in the valley 12a along the valley 12a in the corrugated pipe 12, and is made of a conductive material through which electricity flows. The second signal line 13-2 is also disposed continuously along the first signal line 13-1 in the valley 12a, and is spaced apart from the first signal line 13-1 to prevent a short circuit.

The first signal line 13-1 and the second signal line 13-2 are normally spaced apart from each other, but when a leak occurs in the water supply hose 11, the first signal line 13-1 and the second signal line 13-2 are shorted to each other by a leak filled into the valley 12a. A closed circuit (see closed line in Fig. 5) is constituted.

Accordingly, a shutoff signal of a valve installed at the inlet pipe IP side and supplying water to the water purifier WP is transmitted through a closed circuit formed by the first signal line 13-1 and the second signal line 13-2. . More precisely, the blocking signal uses the operating power supplied from the DC power supply 20.

The first signal line 13-1 and the second signal line 13-2 as described above are extruded to form a corrugated pipe 12 by extruding a molten raw material of a flexible material such as silicon, rubber or plastic, and an extruder (or a drawing) In the line supply member installed at the front end of the discharge side, the signal lines 13-1 and 13-2 may be wound in a spiral direction and introduced into the valley 12a of the corrugated pipe 12.

On the other hand, as can be seen more clearly through the partial enlarged view of FIG. 2, the present invention preferably further includes a double-sided adhesive tape 14, one side is attached to the valley (12a) formed in the corrugated pipe (12).

In this case, the first signal line 13-1 and the second signal line 13-2 are bonded to the other side of the double-sided adhesive tape 14. Therefore, the first signal line 13-1 and the second signal line 13-2 are firmly fixed in the valleys 12a of the corrugated pipe 12, respectively, and are normally kept spaced from each other.

In addition, as shown in Fig. 4, the surface of the first signal line 13-1 and the second signal line 13-2 is covered with a fiber braided coating 13-F made of a non-conductive material that can absorb water, respectively. desirable.

Since the fiber braided sheath 13-F constitutes a sheath of the first signal line 13-1 and the second signal line 13-2, the first signal line 13-1 and the second signal line 13- are provided as long as there is no leakage. Even if 2) touches each other, they are prevented from being electrically shorted to each other.

However, even when the fiber braided sheath 13a is applied to the first signal line 13-1 and the second signal line 13-2 in order to prevent an incorrect short circuit caused by moisture other than leakage, the first signal line 13-1 ) And the second signal line 13-2 may be fixed to be spaced apart from each other in the valley 12a of the corrugated pipe 12.

Hereinafter, with reference to the accompanying drawings will be described with respect to the water leakage blocking system for water purifier according to the present invention.

Pipe water leakage blocking system for water purifier according to the present invention is configured to further include a DC power supply device 20 and a magnetic valve 30 in addition to the water leak detection pipe 10 for water purifier described above.

At this time, as shown in FIG. 5, the water leak detection pipe 10 for water purifier supplies water from the inlet pipe IP to the water purifier WP as described above, and water leaks from the water supply hose 11 and leaks. The first signal line 13-1 and the second signal line 13-2 arranged side by side in the spiral direction along the valley 12a of the corrugated pipe 12 are short-circuited by leaks.

In addition, the DC power supply device 20 is to close the valve by applying power to the magnetic valve 30, and the first signal line 13-1 and the second signal line 13-2 are leaked by water. As a short circuit forms a closed circuit, it starts to supply power through the closed circuit.

In addition, the magnetic valve 30 is installed between the inlet pipe (IP) and the water supply hose 11 to control the opening and closing of the water supply line, the magnetic field is generated when the power is supplied from the DC power supply (20) Close the water supply line to supply water to (WP).

That is, the first signal line 13-1 and the second signal line 13-2 extending in a state separated from the inlet pipe IP and the magnetic valve 30 toward the water purifier WP, respectively, are leaked. As short-circuited with each other in position, they form a closed circuit (see dashed line).

Accordingly, the first signal line 13-1, the positive pole of the DC power supply 20, the negative pole of the DC power supply 20, the first power terminal of the magnetic valve 30, the magnetic valve While the closed circuit connecting the second power supply terminal and the second signal line 13-2 of 30 is configured, power of the DC power supply device 20 is applied to the magnetic valve 30.

However, the magnetic valve 30 includes a plunger (see '34' in FIG. 6B) for opening and closing the water supply line, but the plunger 34 has an on / off state only when the plunger 34 is pressed. It is preferred that a toggle gear switch (see '35' in Fig. 6b) is provided.

The toggle gear switch 35 maintains an on or off state every time a button is pressed, such as a so-called tip pen, and closes the water supply line due to leakage even after the power supply is stopped from the DC power supply 20. It allows you to maintain state.

More precisely, when water is leaked while supplying water to the water purifier WP through the water leak detection pipe 10 for the water purifier, the magnetic valve 30 supplied by the DC power supply device 20 operates to perform a closing operation. Maintain that state.

In order to continue to use the water purifier (WP) by opening the closed valve after repairing the leak or replacing the pipe, supply power to the magnetic valve 30 or release by pressing a separate push button.

6A through 6F illustrate the magnetic valve 30 described above as an embodiment.

The magnetic valve 30 is not particularly limited as long as it can close the valve as the magnetic force is generated by the power supplied when the leakage occurs. In addition, if the toggle gear switch 35 can be kept closed, the application thereof is not particularly limited.

6A to 6E illustrate a ball pen type magnetic valve 30 as an example. 6A to 6E are referred to as ball pen type magnetic valves 30 in that they have a toggle gear switch 35 like a tip ballpoint pen.

As shown in FIG. 6A, the ballpoint-type magnetic valve 30 applicable to the present invention includes a valve body VB in which a flow path is largely formed, and a magnetic drive part MD for opening and closing the flow path. The valve body VB and the magnetic drive unit MD are coupled to each other by the bracket B.

At this time, the valve body (VB) has an inlet (IN) connected to the inlet pipe (IP) (second discharge side), and the outlet (OUT) and the valve body (VB) connected to the leak detection pipe 10 for water purifier of the present invention. It is provided in the interior and includes a guide (TE) connecting between the inlet (IN) and the outlet (OUT).

Accordingly, as the guide opening TE is opened or closed by the magnetic driving unit MD, water is supplied from the inlet IN of the inlet pipe IP to the outlet OUT of the water purifier WP, or the water supply is closed. It stops.

In addition, each configuration of the magnetic drive unit (MD) is assembled in the housing (H), the bobbin (39) assembled inside the housing (H) coil is wound around the core (assembled therein as will be described later when supplying power) Magnetic force is generated at 36, and a terminal T for assembling the coil is assembled at one side of the rear end. The terminal T is connected to the DC power supply 20.

6E, the exploded perspective view of FIG. 6E will be described in more detail with reference to the cross-sectional view of the valve body VB. The valve body VB has a tubular shape in which the inlets IN and the outlets OUT are respectively extended at left and right sides thereof, and are exposed therein. The guide opening (TE) of the upper opening is connected to the inlet (IN) and the side is connected to the outlet (OUT).

As a result, the water for the water purifier WP is supplied from the inlet IN to the outlet OUT as the upper opening of the guide TE is opened or closed by the diaphragm 31 provided at the front of the magnetic drive unit MD. Or interrupted (supply interrupted).

Meanwhile, the magnetic drive unit MD includes a diaphragm 31, a holder 32, a valve seat 33, a plunger 34, a toggle gear switch 35, a core 36, a spring 37, and a push. A guide 38, a bobbin 39, a housing H, and a bracket B are included.

At this time, the diaphragm 31 is provided in the front end of the magnetic drive unit MD is configured in a plug shape for opening or closing the guide (TE) of the valve body (VB) by the plunger 34, holder 32 Is connected to the diaphragm 31.

The valve seat 33 is connected to the end of the plunger 34 and is configured to simultaneously move the diaphragm 31 and the holder 32 in the front-rear direction. Alternatively, the diaphragm 31 elastically installed to be spaced apart from the guide TE may be pressed to press the holder 32 while being separated from the holder 32 so as to block the guide TE.

Next, the valve seat 33 is fixed to the edge part of the plunger 34, and the toggle gear switch 35 is rotatably fitted in the outer periphery. In addition, the core 36 is spaced apart from the rear portion of the plunger 34, and both ends of the spring 37 are fixed to the coupling holes provided in the plunger 34 and the core 36, respectively.

The spring 37 is used to open the valve as it is installed to pull the plunger 34 toward the core 36 by the elastic force, whereas the core 36 causes the plunger 34 to move from the valve body VB when the magnetic force is generated. It is used to close the valve by pushing it toward the guide (TE) side.

As shown in FIG. 6C, the valve seat 33, the plunger 34, the toggle gear switch 35, the core 36 and the spring 37 are assembled into one to form a plunger 34 module, and such a plunger 34. The module is inserted and assembled in the push guide 38.

Furthermore, the push guide 38 into which the plunger 34 module is inserted is inserted into the bobbin 39. A coil (not shown) is wound around the bobbin 39, and the outer side of the bobbin 39 on which the coil is wound is assembled so as to surround the housing H, and the terminal T of the housing H connected to the coil wound around the inside. ) Is connected to the DC power supply 20.

At this time, the above-described toggle gear switch 35 includes a driving gear 35a and a locking gear 35b, the driving gear 35a is rotatably assembled in the fitting groove of the plunger 34, and the locking gear 35b. ) Is rotated a certain distance forward and backward at the same time as the rotation.

Further, as is known, the front end of the drive gear 35a has an inclined surface such that when the drive gear 35a pushes the catching gear 35b forward (that is, pressing a button of a tip ballpoint pen), the catching gear 35b Rotate at the set angle while moving slightly forward.

In addition, the locking gear 35b has a locking portion repeatedly formed at a predetermined angle along the circumferential direction, and the locking portion 38a alternately formed at a predetermined angle on the inner circumferential surface of the push guide 38 as shown in FIG. 6D. It is located in the passage 38b.

That is, as the locking gear 35b moves forward while the locking gear 35b is rotated, the valve closing state is maintained when the locking portion is positioned at the locking jaw 38a of the push guide 38. On the other hand, when the locking gear 35b is rotated again by the drive gear 35a, the locking portion is located in the release passage 38b of the push guide 38 and moves backward by the spring 37 to open the valve.

6E shows the assembled state of the magnetic valve 30 described above in cross section. As shown, the permanent magnet 34a is fixed to the rear portion of the plunger 34, and the permanent magnet is exposed to the core 36 in the push guide 38.

In addition, since the coil (not shown) is wound around the bobbin 39 assembled outside the core 36, the DC power supply device 20 may be connected to the terminal T exposed to the outside through the housing H when water is leaked. When power is applied, the core 36 becomes magnetic like a magnet. This core 36 exerts a repulsive force to push the permanent magnet 34a fixed to the rear portion of the plunger 34.

Therefore, when a leak occurs, the plunger 34 moves forward and the valve seat 33 presses the diaphragm 31 to close the valve (closes the guide), and at this time, the toggle gear switch ( 35) to keep the valve closed.

In the above, the specific Example of this invention was described above. However, the spirit and scope of the present invention is not limited to these specific embodiments, and various changes and modifications can be made without departing from the spirit of the present invention. Those who have it will understand.
