Referring to FIGS. 1 to 5, the replenishing water filling device according to the present invention includes a main body 10 having a path for supplying replenishing water, a path opening and closing member 20 mounted at one side of the main body 10 and having a path opening and closing bar 30 for selectively opening and closing the path for supplying replenishing water, and a control knob 50 for operating the path opening and closing bar 30.
The main body 10 includes: a tap water pipe connecting port 11 connected with a tap water pipe (not shown) , which supplies tap water; and a heating water pipe connecting port 12 connected with a heating water pipe (not shown) at a point of the opposite side of the tap water pipe connecting port 11. A replenishing water supply path which connecting the tap water pipe connecting port 11 and the heating water pipe connecting port 12 is formed inside the main body 10.
At an approximately central point of the main body 10, the path opening and closing member is formed for selectively opening and closing the path by operation of the path opening and closing bar 30 in a direction to cross the replenishing water supply path.
The main body 10 further includes: a first check valve 13 formed at the left side of the path opening and closing member 20 in order to open the path only in the same direction as supply of replenishing water; and a second check valve 14 formed at the right side of the path opening and closing member 20 in order to open the path only in the same direction as supply of replenishing water.
The main body 10 further includes: a left side fixing cap 15 combined with a left side end portion thereof to block and seal the left side end portion of the main body 10; and a right side fixing cap 17 combined with a right side end portion thereof to block and seal the right side end portion of the main body 10. The right side of the first check valve 13 is supported by a stepped portion inside the main body 10, and the left side is supported by a support piece 16 of the left side fixing cap 15. The left side of the second check valve 14 is supported by a stepped portion inside the main body 10, and the right side is supported by a support piece 18 of the right side fixing cap 17. When the right side fixing cap 17 is separated from the main body 10, heating water can be discharged from the heating water pipe.
The path opening and closing member 20 is provided to selectively open and close the replenishing water supply path has an inner space, and the path opening and closing bar 30 which is mounted in the inner space and can be lifted vertically referring to FIG. 4. A tap water side communication hole 21 and a heating water side communication hole 22 are respectively formed at both opposite sides of the path opening and closing member 20. The inner space of the path opening and closing member 20 is connected with the replenishing water supply path of the main body 10 through the tap water side communication hole 21 and the heating water side communication hole 22.
Referring to FIG. 4, the tap water side communication hole 21 is connected to the replenishing water supply path below from the left side of the path opening and closing member 20, and the heating water side communication hole 22 is connected to the replenishing water supply path above from the right side of the path opening and closing member 20. That is, in FIG. 4, the tap water side communication hole 21 and the heating water side communication hole 22 are respectively formed above and below the path to be located at different heights. A distance between the tap water side communication hole 21 and the heating water side communication hole 22 is at least approximately similar to a length of a slim portion 33 of the path opening and closing bar 30, which will be described later.
The path opening and closing member 20 includes: an emergency discharge portion 23 formed at an upper portion thereof and having a discharge hole 28 of an outwardly open type; and an expanded inner surface 24 formed at a lower portion thereof, wherein the expanded inner surface 24 has an inner diameter getting downwardly smaller. The discharge hole 28 is disposed to discharge the backwardly flowed heating water, which has been introduced into the emergency discharge portion 23, to the outside.
The path opening and closing bar 30 is mounted in the inner space of the path opening and closing member 20 of the main body 10 in order to selectively open and close the replenishing water supply path. In more detail, the path opening and closing bar 30 serves to connect or block the path between the tap water communication hole 21 and the heating water communication hole 22 of the path opening and closing member 20.
The path opening and closing bar 30 has a circular cross section and includes: an upper end portion 31, the slim portion 33 and a path blocking portion 34 formed downwardly from the top in order; and an extension bar 36 formed downwardly from the path blocking portion 34.
The upper end portion 31 selectively opens and closes the path above the heating water side communication hole 22 while being lifted vertically so as to open or close the emergency discharge portion 23, and has a first O-ring 32 formed in the outer surface thereof.
The slim portion 33 is to form a path in a space, which is formed between the tap water side communication hole 21 and the heating water side communication hole 22, of the inner space of the path opening and closing member 20. An outer diameter of the slim portion 33 is smaller than an inner diameter of an inner surface 26 located between the tap water side communication hole 21 and the heating water side communication hole 22 of the path opening and closing member 20 so as to form a gap between the slim portion 33 and the inner surface 26.
The path blocking portion 34 is to selectively connect or block the path between the tap water side communication hole 21 and the heating water side communication hole 22, and has a second O-ring 35 formed in the outer surface thereof. The path blocking portion 34 has an outer diameter which is nearly egual to the inner diameter of the inner surface 26 located between the tap water side communication hole 21 and the heating water side communication hole 22. When the path blocking portion 34 does down, a gap is formed between the path blocking portion 34 and the inner surface 26 above the ίο tap water side communication hole 21 of the path opening and closing member 20, so that the replenishing water introduced through the tap water side communication hole 21 may be introduced into the heating water side communication hole 22 after passing the slim portion 33.
The extension bar 36 is to connect the path opening and closing bar 30 to the control knob 50, is extended downwardly from the path blocking portion 34, and has a third O-ring 37 formed in the outer surface of a lower portion thereof.
A lower support portion 40 is combined with a lower end of the path opening and closing member 20 in order to seal the lower end of the path opening and closing member 20 and support a lower portion of the path opening and closing bar 30. The lower support portion 40 includes a round through hole 41 formed therein so that the extension bar 36 of the path opening and closing bar 30 passes the through hole 41 and is connected to the control knob 50. The lower support portion 40 further includes a lifting contact portion 42 formed at a lower end thereof to protrude outwards from the path opening and closing member 20. The lifting contact portion 42 gets in spiral contact with the control knob 50, which will be described later, in order to lift the path opening and closing bar 30 together with the control knob 50.
The path opening and closing member 20 has a pin retaining portion 25, which is formed at one side of an outer face of the lower end thereof and has a hole.
A spring 27 is mounted between the bottom surface of the path blocking portion 34 of the path opening and closing bar 30 and the top surface of the lower support portion 40 in a compressed state, and serves to push the path opening and closing bar 30 upwardly.
The control knob 50 is to lift the path opening and closing bar 30 vertically, and includes a round recess 51 formed at the center, a hole 52 formed in the bottom of the recess 51, and a pin insertion hole 54 formed at one side thereof. The extension bar 36 of the path opening and closing bar 30 is inserted into the recess 51 of the control knob 50, and then, is fixed to the control knob 50 by a screw entering from the opposite side of the recess 51 into the hole 52. A spirally inclined surface 55 is formed on the recess of the control knob 50 so that the control knob 50 can be lifted spirally while the spirally inclined surface 55 gets in sliding contact with a lifting contact portion 42 of the lower support portion 40.
Hereinafter, an operation of the replenishing water filling device according to the present invention will be described.
First, at the time of initial installation of a boiler, the replenishing water filling device is operated in the same way not only in the case that the heating pipe is filled with heating water but also in the case that replenishing water is supplied in order to replenish heating water. So, a replenishing water supply mode for supplying replenishing water is described, but description of an initial heating water supply mode will be omitted.
In order to fill the heating water pipe with replenishing water, as shown in FIG. 4, a user rotates the control knob 50 in order to align the pin insertion hole 54 of the control knob 50 and the pin retaining portion 25 formed at the lower portion of the path opening and closing member 20, and then, inserts a fixing pin 60 so that the control knob 50 is fixed to the pin retaining portion 25. The reason that the control knob is fixed after being rotated is as follows. If a supply amount of replenishing water is small when the replenishing water is supplied, the user only needs to hold the control knob for a moment in the state where the control knob is rotated. However, if there is a great deal of supply amount of replenishing water or if the heating pipe is filled with heating water at the time of initial installation of a boiler, the user has to hold the control knob for a long time. Therefore, if the control knob of the rotated state is fixed by the pin, it can reduce inconvenience that the user has to hold the control knob for a long time.
Here, when the control knob 50 is rotated, the spirally inclined surface 55 of the control knob 50 and the lifting contact portion 42 of the lower support portion 40 get in sliding contact with each other, and the lifting contact portion 42 pushes the spirally inclined surface 55 downwardly so that the control knob 50 moves downwardly and the path opening and closing bar 30 connected to the control knob 50 also moves downwardly while compressing the spring 27.
when the path blocking portion 34 moves downwardly by downward movement of the path opening and closing bar 30, a gap is formed between the inner surface 26 of the path opening and closing member 20 above the tap water side communication hole 21 and the path blocking portion 34. The replenishing water, which was introduced through the tap water pipe connecting port 11 and introduced into the tap water side communication hole 21 after passing the first check valve 13 is introduced into the inner space above the path blocking portion 34 through the gap between the inner surface 26 and the path blocking portion 34. The replenishing water introduced into the inner space moves through the space between the slim portion 33 and the inner surface 26 of the path opening and closing member 20, and then, moves to the heating water pipe connecting port 12 after passing the heating water side communication hole 22. After that, the replenishing water moving to the heating water pipe connecting port 12 is introduced into the heating water pipe connected to the heating water pipe connecting port 12 in order to replenish heating water.
Here, because the path opening and closing bar 30 is in the descended state, the upper end portion 31 of the path opening and closing bar 30 blocks a lower portion of the emergency discharge portion 23. Therefore, the replenishing water introduced into the gap between the slim portion 33 and the inner surface 26 is not discharged to the emergency discharge portion 23, but is entirely supplied to the heating water pipe through the heating water side communication hole 22 in order to replenish the heating water.
Hereinafter, heating performed after supply of the replenishing water is finished will be described.
When the user pulls out the fixing pin 60 which fixes the control knob 50 after completion of supply of replenishing water, the path opening and closing bar 30 is lifted by restoring force of the compressed spring 27, and the control knob 50 connected to the path opening and closing bar 30 is lifted while the spirally inclined surface 55 slides and rotates along the lifting contact portion 42 so as to be returned to its original position.
When the path opening and closing bar 30 is lifted, the path blocking portion 34 gets in contact with the inner surface 26 directly above the tap water side communication hole 21 and closes the path above the tap water side communication hole 21. Therefore, even though replenishing water is introduced through the tap water communication hole 21, because the path above the tap water side communication hole 21 is closed by the path blocking portion 34, the introduced replenishing water does not go above the path blocking portion 34. So, in the heating mode, it is blocked that the replenishing water is introduced into the heating pipe .
The second check valve 14 located at the heating water pipe connecting port 12 serves to prevent backwardly flowed heating water from being introduced into the tap water pipe if heating water flows backwardly in the heating water pipe.
If heating water flows backwards and the second check valve 14 does not fulfill its function due to a damage, the backwardly flowed heating water may be introduced into the inner space of the path opening and closing member 20 through the heating water side communication hole 22. However, even though the heating water flowed backwards is introduced to the inner space, because the path blocking portion 34 blocks the path between the heating water side communication hole 22 and the tap water side communication hole 21 in the state where the path opening and closing bar 30 is lifted, the backwardly flowed heating water cannot move down the path blocking portion 34. Furthermore, because the upper end portion 31 of the path opening and closing bar 30 is lifted in the heating mode, there is a gap between the upper end portion 31 and the expanded inner surface 24 of the emergency discharge portion 23, so the backwardly flowed heating water is introduced into the emergency discharge portion 23 through the slim portion 33 and is discharged to the outside through the discharge hole 28. That is, even though the second check valve 14 is damaged and the backwardly flowed heating water is introduced into the inner space of the path opening and closing member 20, the heating water is not introduced into the tap water pipe but is discharged to the outside through the emergency discharge portion 23.
Because the extension bar 26 of the path opening and closing bar 30 is small in outer diameter, friction force by the third 0-ring 37 is relatively small, the second 0-ring 35 causes small friction force since a distance that the second 0-ring 35 rubs against the inner surface 26 of the path opening and closing member 20 is short, and the third 0-ring 37 of the upper end portion 31 also causes small friction force since a diameter of the upper end portion 31 is small and a distance that the third 0-ring 37 rubs against the inner surface 26 is also short. Therefore, an operating force of the control knob 50 necessary for lowering the path opening and closing bar 30 may be minimized.
While the exemplary embodiments of the present invention have been described in more detail with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that the present invention is not limited to the exemplary embodiments, and the scope of the present invention should be construed based on the following appended claims and it should be construed that the technical spirit included within the scope equivalent to the claims belongs to the present invention.
