Description

Water Flow Switch for Boiler {FLOW SWITCH OF BOILER}

The present invention relates to a water flow switch for a boiler, and more particularly, a permanent magnet and a reed switch for detecting a water supply state by a water supply pressure introduced into the inside, and a water flow switch main body and a counterpart to which water is supplied. In order to enable direct coupling with the connection portion and the water supply valve for replenishing the heating water of the water tank for the heating pipe selectively to be made integrally with the main body.

In general, a water flow switch is installed in the gas boiler to supply water to a counterpart such as a heat exchanger or a hot water heat exchanger. A reed switch is provided in the water flow switch to detect a water supply state.

In addition, a separate copper pipe is connected and installed to connect the counterpart and the water flow switch, and a water replenishment valve is made of the same material in the brass structure at the bottom of the water flow switch to compensate for the lack of water in the heating water tank. .

However, the conventional water flow switch as described above detects whether the water supply state inside the contact with the permanent magnet rotated by water pressure and the lead switch, in which case the permanent magnet impacts the reed switch, the failure of the reed switch In this case, there is a problem in that all of the water flow switches are replaced when the lead switch is broken.

In addition, due to the use of separate copper pipes for the connection of the water flow switch and the heat exchanger, the work process and the production cost of the pipes increase, and if the pipe connection is not made securely or used for a long time, There was a problem of leaks.

In addition, the installation of a water refill valve for replenishing water in the water tank for heating is made of a metallic material in the brass structure has caused a problem of rising manufacturing costs.

The present invention has been made to solve the above-described problems of the prior art, by connecting the water flow switch and the heat exchanger and by constituting a water filling valve for supplying water to the water tank integrally with the main body, simplifying and producing the piping structure It is possible to reduce the unit price for this purpose.

In addition, the purpose is to facilitate the failure prevention and replacement of the reed switch.

The object is that the inlet and outlet of the water supply is communicated in a right direction, and the permanent magnet is hinged to be rotatable by the water supply pressure is introduced therein, to detect the water supply state according to the operation of the permanent magnet In a boiler water switch with a reed switch for:

The water flow switch main body is integrally formed with a connection portion extending from the outlet side and a water refill valve for selectively replenishing the heating water with a water tank so as to allow direct coupling with a counterpart to which water is supplied; The permanent magnet is coupled to a detachable cap having a built-in reed switch, the detachable cap is configured to be detachable from the water flow switch body, and the detachable cap is configured as a stopper for preventing direct contact during rotation of the permanent magnet. This can be achieved through the water flow switch structure.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a water flow switch for a boiler according to the present invention, the injection-molded cap detachable cap 30, which has a reed switch 28 on the upper side of the main body 10 of the original resin material is combined with the main body 10 On the other side, the connection part 20 which is assembled with the hot water heat exchanger 24 has an integral structure, and on the lower side, the water supplement valve 26 has a main body so that the user can selectively supply water to the heating water tank. It is also made integral with the 10, and the body 10 is provided with a water refill port 16 to send water supplied by the water refill valve 26 to the water tank on one side.

At this time, the outer circumferential surface of the connecting portion 20 is provided with an airtight ring 40 for preventing leakage of water after assembling the stepped water and the hot water heat exchanger 24.

In addition, the detachable cap 30 configured to be detachable from the main body 10 has a reed switch 28 as illustrated in FIGS. 2 to 3, and a stop 32 on one side of the detachable cap 30. ) Is provided at a predetermined height, and on the other side, the permanent magnet 36 is rotatably coupled by the support 38 and the hinge 34.

The effect of the operation of the water flow switch of the present invention constituting such a configuration will be described.

When water is supplied to the inlet 12 provided at the bottom of the main body 10, the permanent magnet 36 provided at the lower portion of the detachable cap 30 is rotated by the water supply pressure based on the hinge 34, and the support ( 38 is detected by the permanent magnet 36 in contact with the stopper 32 provided in the lower part of the reed switch 28 by the permanent magnet 36, the water supply is through the outlet 14 formed in a right angle direction hot water heat exchanger Supplied to (24).

At this time, the prevention magnet 32 has a permanent magnet 36 and the reed switch 28 has a constant spacing (d), which is the reed switch 28 is operated by the magnetic force is in contact with the permanent magnet 36 Even if the reed switch 28 detects the magnetic force, it is possible to prevent the impact caused by the contact of the reed switch 28 and the permanent magnet 36, so that the reed switch 28 is effectively prevented from being damaged Will be.

When the supply of water is stopped, the support 38 rotates based on the hinge 34 by its own weight to return to its original position, and the reed switch 28 does not sense the magnetic force of the permanent magnet 36 so that the water is supplied. You can see that this has stopped.

On the other hand, when there is insufficient water in the water tank for heating, the user can supply water to the water tank using the water refill valve 26, for this purpose, if the user rotates the water refill valve 26, the water refill port (16) The oil passage is opened, and the water supplied into the water flow switch is supplied to the water tank provided in the boiler through the water refill 16 to supplement the water supply to the water tank for heating.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the water flow switch for the boiler of the present invention may be variously modified and implemented by those skilled in the art.

However, these modified embodiments should not be individually understood from the technical spirit or prospect of the present invention, and the modified embodiments should fall within the appended utility model registration claims of the present invention.

As described above, the water flow switch of the present invention is provided in the main body by a detachable cap so that a reed switch and a permanent magnet for detecting a water supply state can be detached and easily replaced when the reed switch is damaged. It is possible to prevent breakage of the reed switch by providing the prevention jaw to prevent the shock applied to the reed switch when the magnet is rotated, so that it can be used safely and comfortably without fear of boiler failure.

In addition, since the injection molding is integrated with the main body and the water refill valve to selectively replenish the heating water with the water tank and the connection part combined with the hot water heat exchanger, the manufacturing cost of the product can be reduced, and the flow path to the heat exchanger can be reduced. There is an effect that can solve the problem of the conventional water supply leakage occurred when using the intermediate connecting member for.
