1 is a schematic block diagram of an outlet equipped with a fire detection function according to an embodiment of the present invention, and FIG. 2 is a view for explaining a housing.

Hereinafter, an outlet equipped with a fire detection function according to an embodiment of the present invention will be referred to as'this device' for convenience of description.

Referring to FIGS. 1 and 2, the device (outlet with a fire detection function) includes a housing (H), a light detection unit (1), a temperature detection unit (2), and a control unit (3).

The housing H may include a terminal connection part and a power line connection part. More specifically, the housing (H) will be described in more detail in the following description, but includes a main body (H1) for accommodating a terminal connection portion and a power line connection portion, and a cover formed with a through hole through which the ground terminal, etc. I can. Inside the housing H, the terminal connection part, the power line connection part, etc., which are configurations of an outlet, may be accommodated. In this regard, since it is commonly used in the relevant field, a more detailed description will be omitted.

Referring to FIG. 1, a light sensing unit 1 is provided on the housing H side, and generates light information by measuring an amount of light. Hereinafter, the amount of light sensed (or measured) by the light sensing unit 1 may be referred to as a sensed amount of light.

The light sensing unit 1 is for measuring the amount of light generated by a flame or the like when a fire occurs, and may be provided inside or outside the housing H.

Exemplarily, the light sensing unit 1 may be an illuminance sensor, and the illuminance sensor may transmit a current corresponding to the resistance value to the controller 3 to be described later by changing a resistance value according to the amount of light. It could be information.

The light sensing unit 1 may be an illuminance sensor, but is not limited thereto.

Referring to FIG. 1, the temperature sensing unit 2 generates temperature information by measuring the temperature inside or outside the housing H. Hereinafter, the temperature sensed (or measured) by the temperature sensing unit 2 may be referred to as a sensed temperature.

That is, the temperature sensing unit 2 measures the temperature inside and outside the housing H, which is variable by heat generated by the flame when a fire occurs.

The temperature sensing unit 2 may be provided inside or outside the housing H. In addition, the temperature sensing unit 2 may be, for example, a thermometer using the principle of thermal expansion of a liquid, or a temperature sensor including a metal wire or a semiconductor whose resistance value changes according to temperature. That is, the temperature information may mean a numerical value indicating a degree of thermal expansion of a liquid in a thermometer or a resistance value in a temperature sensor.

The temperature sensing unit 2 is not limited to a thermometer or a temperature sensor.

Referring to FIG. 1, the control unit 3 receives the light information and the temperature information, and sets the amount of light included in the light information (the amount of light detected) and the temperature included in the temperature information (the sensed temperature) according to a preset standard. Fire information is generated when the amount of light and the reference temperature are exceeded.

The fire information may be transmitted to an output unit (not shown). The output unit (not shown) may be an alarm, a portable terminal, a control PC, or the like.

Various control configurations or computing devices (eg, various electronic devices or electronic modules such as computers and processors) known to those skilled in the art may be applied to the control unit 3. For example, the control unit 3 may be configured to transmit a signal or command generated according to a program or algorithm included therein to an output unit (not shown). For example, the control unit 3 is an internal configuration installed in the output unit (not shown), or is provided separately from the output unit (not shown) at a location adjacent to the output unit (not shown) and is connected by wire or wirelessly. It can be an independent configuration.

Exemplarily, since the amount of light inside or outside the housing H in the indoor space in which the device is installed varies depending on the on/off state of the lighting in the indoor space, the controller 3 is in a state where the lighting is turned on in the indoor space. It may include a calibration illuminance sensor (not shown) that measures the brightness of an indoor space in each of the (on) and off (off) states to generate a reference amount of light, and the amount of light included in the optical information (the amount of detected light) is a reference Fire information can be generated when the amount of light is exceeded.

In addition, the control unit 3 may include a calibration thermometer (not shown) that measures the temperature of the indoor space, generates the reference temperature, and transmits the reference temperature to the control unit 3, and the control unit 3 transmits the reference temperature. It is possible to generate fire information when the detected temperature exceeds the reference temperature by comparing it with the sensed temperature included in the temperature information received and transmitted by the temperature sensing unit 2.

As another example, the controller 3 may generate fire information when each of the detected temperature and the amount of light that is sensed rapidly changes.

As described above, the apparatus includes a control unit 3 that receives the light information and the temperature information, and generates fire information when each of the sensed light amount and the sensed temperature exceeds a preset reference light amount and reference temperature, In the event of a fire, it has the advantage of inducing a quick response.

In particular, since the amount of light and the temperature are checked at the same time, it is more accurate because it prevents malfunctions that generate fire information by abnormally measuring (detecting) a large amount of light or temperature due to various reasons such as boiling water entering the device. There is an advantage of being able to recognize the presence or absence of a fire.

Referring to FIG. 1, the device may include a human body sensing unit 4 provided on the housing H side and generating human body information when a human body is sensed.

In this case, when receiving the human body information, the controller 3 may generate a changed reference light amount by changing the reference light amount by a predetermined amount, and change the reference temperature by a predetermined size to generate the changed air temperature.

For example, the human body detection unit 4 may be a PIR sensor, but is not limited thereto.

The control unit 3 may include a DB (database) that stores data.

Illustratively, when the human body approaches the device while the light is on (on) in an indoor space and the human body detection unit 4 generates human body information, the control unit 3 reduces the reference amount of light by a predetermined size. It is possible to generate a changed reference amount of light. At this time, the control unit 3 can detect the change amount (data) of the detected light amount when receiving the human body information in the calibration step when the light is on (on), and store the change amount of the detected light amount in the DB. The amount of change in the amount of light becomes the predetermined size.

Similarly, when the human body detection unit 4 detects the human body, radiation is emitted from the human body, and the human body detection unit 4 itself generates heat, so that the temperature of the housing H side may increase. Accordingly, when receiving the human body information, the control unit 3 may generate a changed reference temperature by reducing the reference temperature by a predetermined predetermined size. At this time, when receiving the human body information, the control unit 3 may store the change amount (data) of the temperature sensed in the calibration step in the DB, and the amount of change of the sensed temperature becomes the predetermined size.

If the control unit 3 receives the human body information, the detected amount of light and the detected temperature may be compared with the changed reference amount of light and the changed reference temperature to determine whether or not fire information is generated.

As described above, the device includes a human body detection unit 4 and a control unit 3 that generates a changed reference light amount and a changed reference temperature when receiving human body information, so that even if the environment changes by the human body, it is possible to more accurately determine whether or not a fire has occurred. There is an advantage of being able to do it.

Although not shown, the device may include a standby power blocking module that blocks standby power. That is, the present apparatus may include a standby power cut-off module to automatically cut off standby power so that energy saving can be achieved. Since the outlets including the standby power blocking module and the standby power blocking module are commonly used in the relevant field, a more detailed description will be omitted.

At this time, in the present apparatus, when the standby power blocking module blocks standby power, the control unit 3 may change the reference temperature by a predetermined size to generate the corrected reference temperature.

When the standby power cut-off module cuts off standby power, the temperature inside and outside the housing (H) decreases due to a decrease in electrical resistance in the wire, so when the standby power is cut off, it decreases inside or outside the housing (H). It is possible to more accurately identify the occurrence of a fire even when standby power is cut off by changing the temperature as much as (a predetermined size) and generating a modified reference temperature.

Similarly, the control unit 3 detects the temperature difference inside or outside the housing H when the standby power is not cut off and when the standby power is cut off, and when the standby power is cut off, the reference temperature is reduced by the temperature difference. It is possible to create a modified reference temperature.

On the other hand, when receiving the inje information, the control unit 3 may control the standby power cut-off module not to be driven.

Referring to FIGS. 1 and 2, when the housing H is described in more detail as described above, the housing H may have a terminal connection part, a power line connection part, a safety pin, a waterproof packing, and the like installed inside the housing H.

Since such a housing (H) includes a terminal, etc. inside, it is necessary to reduce the part exposed to the outside as much as possible in order to suppress the occurrence of corrosion, and at the same time, the housing (H) has the above terminal connection, power line connection, safety pin, One side needs to be opened to facilitate installation, such as a waterproof packing. Particularly, when a conductive wire with some bare sheath is connected to the terminal, one side needs to be opened in order to minimize structural obstacles.

As a means for solving the above problem, the housing (H) is a body (H1) having an opening (H11) and an internal space (H12) on one side of the housing (H), and the opening (H11) is combined with the body (H1). It may include a cover (H2) covering the, and a sealing coupling means (C) for coupling and sealing the body (H1) and the cover (H2).

Here, the cover H2 may mean a cover in which a through hole is formed, or may be different from each other covering different open portions (eg, the opening H11) of the housing H, such as a cover.

The sealing coupling means (C) includes a binding groove (C1) formed along the circumference of the main body (H1), an extension groove (C2) formed on the wall surface of the binding groove (C1), and a cover (H2) on the wall of the extension groove (C2). The access hole (C3) formed toward the side, the binding protrusion (C4) provided along the circumference of the cover (H2) and inserted into the binding groove (C1), provided along the circumference of the cover (H2) and corresponding to the entrance hole (C3) A locking pin that is accommodated in the locking groove (C5) formed at the position, the sealing member (C6) provided on the outer surface of the binding protrusion (C4), and the entrance hole (C3) to move forward and backward, and the front end is inserted into the locking groove (C5) when moving forward. Including (C7),

The sealing member C6 includes a heating part C61 that generates heat by an impact of a threshold value or more, and an expansion part C62 that is provided outside the heating part C61 and expands by heat generation.

As described above, since the housing H has the opening H11, accessibility to the internal space H12 is improved, so that operations on the internal configuration, such as assembly, wiring, replacement, soldering, etc., are easy. In addition, in order to have the above-described opening (H11) by the sealing coupling means (C), the deterioration of the airtightness caused by taking the powder coupling form can be prevented without additional equipment, additional tools, and skilled techniques, and furthermore, the main body ( It is possible to improve the bonding force and the bonding holding force between H1) and the cover (H2).

(In the following description, for convenience of explanation, top, bottom, left, and right will be set and described with reference to Fig. 2. This particular direction should not be construed as an element limiting the scope of the present invention. .)

Referring to FIG. 2, more specifically, first, the binding groove (C1) is a groove formed along the circumference of the body (H1) on the end side of the body (H1), and the overall shape of the binding groove (C1) is the body It follows the shape of (H1). This binding groove (C1) is formed by being recessed downward along the circumference of the main body (H1) from the top.

And the extension groove (C2) is a groove formed on the wall surface (side wall surface based on the drawing) of the binding groove (C1), the overall shape of the extension groove (C2) also follows the shape of the main body (H1). The binding groove (C1) and the extension groove (C2) described above take a continuous groove structure along the circumference of the main body (H1).

And the entrance hole (C3) is formed toward the cover (H2) from the wall surface of the extension groove (C2). Exemplarily, the entrance hole C3 may be a through hole passing through the upper wall surface adjacent to the cover H2 in the extension groove C2 and an upper end of the main body H1.

In addition, the binding protrusion C4 is provided to protrude from the lower end along the circumference of the cover H2 to be inserted into the binding groove C1 when the main body H1 and the cover H2 are coupled.

And the locking groove (C5) is a groove recessed upward from the lower end of the cover (H2), likewise formed at a position corresponding to the entrance hole (C3) along the circumference of the cover (H2).

And the sealing member (C6) is provided on the outer surface of the binding protrusion (C4). The sealing member C6 includes a heating part C61 that generates heat by an impact of a threshold value or more, and an expansion part C62 that is provided outside the heating part C61 and expands by heat generation. In more detail, the heating unit C61 includes 50 parts by weight of water relative to 80 parts by weight of sodium acetate, and is accommodated in the heat conductor C63. The heating unit C61 may be provided by dissolving sodium acetate in water in a supersaturated state.

This heating part (C61) is pressed by the lower wall of the cover (H2) and the binding groove (C1) during the coupling process between the cover (H2) and the body (H1), and generates heat by receiving an impact above a threshold value, and the heating temperature is It is about 50 ~ 90 ℃.

The expansion part (C62) is characterized in that it further comprises 1 part by weight of polyol di(meth)acrylate and 13 parts by weight of hydrofluoro ether, based on 100 parts by weight of cellulose ester.

In the above, the cellulose ester is used as a thermoplastic polymer constituting the polymerizable monomer, and the glass transition temperature is 30 to 120°C, and the glass transition temperature is lowered to 55°C by the crosslinking agent described later. Other compositions of the expanded portion (C62) are based on 100 parts by weight of this cellulose ester.

Polyol di(meth)acrylate is added as a crosslinking agent, and the molecular weight between the crosslinking points is so large that the viscosity of the expanded portion (C62) is increased without deteriorating the foaming properties of the hydrofluoroether without excessively increasing the crosslinking density of the polymer resin. In addition, there is an effect of lowering the glass transition temperature of the expansion part C62 to enable foaming at a low temperature. If the polyol di(meth)acrylate is too small, the thickening effect is insignificant and can be easily torn during foaming. If it is excessive, the crosslinking density becomes too high and the foaming ratio decreases. As a result of repeated experiments, the content showing the optimum foaming properties was 4 parts by weight.

Hydrofluoroether is added as a blowing agent, and its content is preferably 13 parts by weight. When the expansion part C62 is heated by the heating part C61, the thermoplastic polymer softens and the internal pressure of the foaming agent increases, thereby expanding the volume.

And the locking pin (C7) is accommodated in the entrance hole (C3) to move forward and backward (up and down based on the drawing), and the front end is inserted into the locking groove (C5) when moving forward. A description of specific matters in which the locking pin C7 is accommodated in the entrance hole C3 will be omitted, and the general knowledge will be followed.

The above-described sealing coupling means (C) largely provides two effects, one to completely seal the gap occurring in the coupling portion between the body (H1) and the cover (H2), and the other is to completely seal the body (H1). ) To improve the bonding force between the cover (H2) and the holding power and to suppress the shaking of the cover (H2).

Summarizing the operation and effect of the sealing coupling means (C) with reference to Figure 2, in the state of Figure 2 [A], the heating part (C61) is an impact applied when the main body (H1) and the cover (H2) are coupled to each other. By heating, the expansion part C62 is expanded, and the gap between the main body H1 and the cover H2 is filled and completely sealed as shown in FIG. 2 [B]. And in this process, the expansion part (C62) expands and is filled in the extension groove (C2), so that the locking pin (C7) is advanced so that the locking pin (C7) is inserted into the locking groove (C5), and the main body (H1) It realizes the coupling and locking structure between the and the cover (H2).

The present invention described above with reference to the accompanying drawings can be variously modified and changed by a person skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
