Description

[0001] Boiler communication with escape detection device [0002]

[0001] The present invention relates to a sensing device for sensing a departure of communication connected to a flue of a boiler, and more particularly, to a sensing device for sensing a disconnection of a communication connection and fixing by a fixing means, The present invention relates to a boiler shut-off sensor.

Generally, a boiler is installed for heating and hot water supply. It uses heat generated by burning various fuels to heat water, directly use the heated water, or to be used for heating a home or various buildings It has been developed and used widely from small boilers for household use to large boilers for industrial use depending on their sizes.

In this way, since the boiler burns fossil fuels such as coal, oil, and gas, combustion gas harmful to the human body such as carbon monoxide is generated. Therefore, in order to prevent gas poisoning accidents, And the combustion gas is discharged to the outside by forming a communication hole for discharging the combustion gas to the outside in the year.

In a conventional conventional boiler, a method for connecting a flue to a flue can be achieved by connecting the flue and the conduit by means of a forced fit or by using a fixing member such as a separate band clamp or a fastening band.

In the case of the electronic interference fit method, since the flue gas and the communication are simply connected by the interference fit, there is a problem that the flue gas leaks on the connection portion. To solve this problem, a method of covering the metal tape is used. However, There is a problem that a gap is generated between the flue and the communication due to the vibration caused by the vibration of the flue gas, or the communication is released from the flue and the combustion gas leaks.

In the latter method, a separate fixing member is required for combining the flue and the communication, and a bolt and a nut are used to connect the flue to the flue through the fixing member. Therefore, There was a troublesome problem.

The present invention is applied to a method of connecting the above-mentioned flue to a communication using a fixing member such as a band clamp or a fastening band.

As described above, in the conventional prior art system of connecting the flue of the boiler with the communication by the fixing member, as disclosed in Korean Registered Utility Model No. 20-0361545 (hereinafter referred to as "Prior Art Document 1"), And a communication fixture which tightens the outer circumferential surface of the upper end of the fl ow and tightens the fl ow with the fl ow so that the fl ow is firmly fixed to the fl ow.

In addition, as disclosed in Korean Utility Model Publication No. 20-2010-0005323 (hereinafter referred to as "Prior Art Document 2"), an insertion groove formed in a cylinder, a protrusion formed in a cylinder, Techniques such as a boiler connection and a flue stabilizing device have been proposed, which include a fixing member for tightly coupling the flue and the flue to each other so that the flue and the flue are firmly coupled.

The prior art documents 1 and 2 have an advantage that the flue and the communication are tightly fixed according to the use of the fixing means to minimize the leakage of the combustion gas. However, due to the installation conditions, the use period, It sometimes caused a problem that the combustion gas is deviated from the room, thereby providing a cause of personnel accidents due to the inflow of the combustion gas into the room.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a boiler shut-off sensor for detecting the disconnection of the connection and fixing of the boiler by the fixing means, .

Fig. 2 is a side view for explaining the use state of the combined state according to Fig. 1. Fig.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The present invention is not limited to the embodiments.

FIG. 1 is a partially exploded perspective view for explaining the present invention, and FIG. 2 is a side view for explaining a use state of the combined state according to FIG.

As shown in the figure, after the communication pipe 120 is inserted into the flue 110 of the boiler 100, the flue 110 and the communication pipe 120 are surrounded by a fixing means 130 such as a usual band clamp or a fastening band A sensing device (1) for detecting the disconnection of the communication pipe (120) in a state in which it is fixed.

The present invention is intended to detect the disconnection of the communication connection and fixation by the fixing means and to stop the operation of the boiler.

The sensing device 1 according to the present invention is configured to detect whether or not the fixing means 130 is detached from the lower flue 110 of the fixing means 130 which is connected and fixed around the flame 110 and the communication pipe 120, Means (10); And a connecting line 20 such as a normal cable connected to stop the driving of the boiler 100 by the control unit 100a of the boiler 100 when the fixing unit 130 is separated by the sensing unit 10. [ Lt; / RTI >

The sensing means 10 is provided in the flue 110 at a position close to the lower portion of the fixing means 130 so as to promptly detect whether the fixing means 130 is detached.

The connection line 20 is preferably connected to the control unit 100a provided in the boiler 100 via the flue 110. The connection line 20 may be connected to an internal control unit through the exterior of the case of the boiler.

In other words, there may be a situation in which the fixing means is not properly fastened or fixed due to an installation condition for setting a communication port, a period of use, a defective part, or the like.

This is because it can not properly perform its role as a fixing means, and it is possible to prevent the combustion gas from leaking into a gap between the flue and the communication, thereby preventing the flue gas from being originally prevented.

That is, in the sensing means of the present invention, when the fixing means for connecting and fixing the flue to the flue is separated or widened at a predetermined interval and is not positioned at the predetermined position, it is determined that the flue is separated, So that the safety of the boiler can be ensured by stopping the operation of the boiler.

In addition, in order to separate the communication, it is possible to originally confirm that the communication is separated and separated due to the reason of separating the fixing means.

In addition, there is a condition that the leakage of the combustion gas due to the expansion between the flue and the communication can be prevented even when the communication is not separated but the fixing means is opened.

Accordingly, the present invention has an advantage that high safety can be ensured by stopping the operation of the boiler by judging that the communication is separated by the sensing means for detecting the separation or separation of the fixing means for fixing the communication fixed to the flue I have.

The sensing means 10 includes a pocket housing 12 which is formed in the lower flap 110 of the fixing means 130 such that the fixing means 130 side is opened and a fixing means 130 inserted into the pocket housing 12, And a conventional sensing sensor 14 connected to the control line 100a of the boiler 100 and the connection line 20,

The pocket housing 12 may be formed integrally with the fl ash when manufactured, or may be separately formed and fixedly coupled to the flue according to a known method.

The sensing sensor 14 may be any known sensor capable of detecting that the securing means is separated or detached in close proximity to the securing means such as a reed switch or a distance sensor, It may be applied.

The fixing unit 130 may further include a conventional sensing unit 16 for sensing whether or not the sensing sensor 14 is sensed.

That is, although it is possible to directly detect the fixing means by the sensing sensor, it is preferable that the sensing unit is provided with a sensing unit for sensing the sensing signal of the sensing sensor more accurately. At this time, the sensing unit may be integrally formed so as to allow the sensing unit to sense the sensing sensor smoothly, or may be fixed separately.

Therefore, the detection sensor can be more accurately sensed by the toughening strip provided on the fixing means, and furthermore, the condition for securing higher safety can be secured.
