Description

Technical Field

[0001] The present disclosure relates to disaster prevention equipment considering environmental issues.

Background Art

[0002] As disaster prevention equipment for detecting and notifying fires, various types of fire detectors, fire alarms, etc. are used. Specific types of fire detectors include, for example, differential spot-type detectors, fixed-temperature spot-type detectors, photoelectric spot-type detectors, and the like. The fire detector monitors a state that changes due to an increase in the ambient temperature or the generation of smoke, and outputs a fire signal when a fire is detected.

[0003] As a specific example of a fire notification system equipped with such a fire detector, in a building, a fire receiver, a transmitter, a repeater, an acoustic device, etc. are arranged at appropriate positions together with the fire detector, and an automatic fire notification facility that protects people inside the building from fires can be cited (for example, see Non-Patent Document 1).

[0004] In the automatic fire notification facility, when the fire detector senses heat, smoke, or flames, it transmits a fire signal to the fire receiver. The fire receiver that has received the fire signal issues an alarm, sounds the acoustic device, and notifies people inside the building of the occurrence of a fire. The automatic fire notification facility disclosed in Non-Patent Document 1 can construct an appropriate system according to the use and scale of the building to be fireproofed.

[0005] On the other hand, when a small-scale area such as inside a home is used as a fire monitoring area, it is not appropriate to use a large-scale system such as an automatic fire notification facility considering costs, installation, etc.

[0006] Therefore, residential fire alarms have been commercialized as fire prevention devices suitable for detecting fires in small areas such as homes (see, for example, Non-Patent Document 2). Residential fire alarms can be installed independently and have a function to output the detection result as an audible signal when a fire caused by smoke or heat is detected.

[0008] Fire prevention equipment for detecting and reporting fires has a structure for detecting fires caused by smoke or heat housed within its casing. In this application, the electrical and mechanical structure housed within the casing for detecting fires caused by smoke or heat will be collectively referred to as the "sensing mechanism."

[0009] Regardless of the size or purpose of the fire monitoring area, the casings used for fire prevention equipment that detects and reports fires are generally made of plastic.

[0010] However, with the global demand for CO2 emission reductions, manufacturers of disaster prevention equipment are expected to need to disclose their efforts to address environmental issues, such as CO2 emission reductions, regarding the disaster prevention equipment they manufacture and sell.

[0011] Furthermore, since fire prevention equipment is installed in environments where fires occur, it needs to have a structure that maintains performance that takes the installation environment into consideration, such as heat resistance, durability, and waterproofing.

[0012] This disclosure is made to solve the above-mentioned problems and aims to provide disaster prevention equipment that takes environmental issues into consideration and has a structure that can maintain performance considering the installation environment. [Means for solving the problem]

[0013] The fire prevention equipment relating to this disclosure is a fire prevention device installed in a fire monitoring area, comprising a sensing mechanism that outputs a fire signal when it detects the occurrence of a fire in the fire monitoring area, and a housing that covers the sensing mechanism, the housing being constructed by coating the surface of a non-plastic material with resin. [Effects of the Invention]

[0014] According to this disclosure, it is possible to obtain disaster prevention equipment that has a structure that takes environmental issues into consideration and maintains performance that takes the installation environment into account. [Brief explanation of the drawing]

[0015] [Figure 1] This is an explanatory diagram relating to the appearance of the disaster prevention equipment according to Embodiment 1 of this disclosure. [Figure 2] This is an explanatory diagram showing the structural features of the housing used in the disaster prevention equipment according to Embodiment 1 of this disclosure. [Figure 3] This is a perspective view showing the internal structure of a differential spot-type sensor in Embodiment 1 of the present disclosure. [Figure 4] This is a perspective view showing the internal structure of a photoelectric spot-type detector in Embodiment 1 of this disclosure. [Modes for carrying out the invention]

[0016] Hereinafter, preferred embodiments of the disaster prevention equipment described herein will be explained with reference to the drawings. The disaster prevention equipment according to the present disclosure is characterized in that the housing is made of a de-plastic material and the surface is coated with resin, taking environmental issues into consideration and realizing a structure that combines heat resistance, durability, and waterproofness.

[0017] Embodiment 1. The disaster prevention equipment according to the present disclosure is used at the fire monitoring site as part of the fire monitoring and notification equipment, and includes a fire detector, a residential fire alarm, etc. FIG. 1 is an explanatory diagram of the appearance of the disaster prevention equipment 100 according to Embodiment 1 of the present disclosure. FIG. 1(A) represents a planar view of the disaster prevention equipment 100 as seen from the side, and FIG. 1(B) represents a three-dimensional view of the disaster prevention equipment 100 as seen obliquely.

[0018] The disaster prevention equipment 100 according to Embodiment 1 of the present disclosure is composed of a housing 10 and a sensing mechanism unit 20, and is installed in a fire monitoring area. Here, in Embodiment 1 of the present disclosure, the "fire monitoring area" means an area where a room, a dwelling unit, a building, etc. are targeted for fire prevention and the occurrence of a fire is monitored by disaster prevention equipment.

[0019] In addition, in Embodiment 1 of the present disclosure, the "sensing mechanism unit 20" is a general term for the electrical and mechanical structures for outputting a fire signal when a fire occurs in the fire monitoring area. Also, in Embodiment 1 of the present disclosure, the "fire signal" output from the sensing mechanism unit 20 includes the signal (fire signal) output when a fire detector senses the occurrence of a fire and the signal (fire alarm) output when a residential fire alarm senses the occurrence of a fire.

[0020] The housing 10 corresponds to a cover that covers the sensing mechanism unit 20, and is divided into a base portion 11 and a main body portion 12 that is detachable from the base portion 11. The base portion 11 is fixedly installed on a wall or the like within the fire monitoring area. On the other hand, the main body portion 12 is detachable from the base portion 11 in a state where the sensing mechanism unit 20 is housed, and is configured to be able to handle maintenance inspections, replacements, etc.

[0021] Figure 2 is an explanatory diagram showing the structural features of the housing 10 used in the disaster prevention device 100 according to Embodiment 1 of the present disclosure. As shown in Figure 2(A), the housing 10 used in the disaster prevention device 100 according to Embodiment 1 is made of a de-plastic material 10a. Specific examples of the de-plastic material 10a include materials mainly made of cellulose nanofibers or reinforced pulp.

[0022] Furthermore, as shown in Figure 2(B), the surface of the de-plastic material 10a of the housing 10 used in the disaster prevention device 100 according to Embodiment 1 is coated with a resin 10b such as silicon or Teflon (registered trademark).

[0023] Therefore, the housing 10 in Embodiment 1 adopts the de-plastic material 10a in consideration of environmental problems, and is coated with the resin 10b in order to have heat resistance, durability, and waterproofness under the environmental conditions where it is installed in the fire monitoring area.

[0024] Next, as a specific example, the case of using a differential spot type sensor 110 and a photoelectric spot type sensor 120 as the disaster prevention device 100 to which the structure of the housing 10 according to Embodiment 1 is applied will be described in detail.

[0025] <1> When applying the structure of the housing 10 to the differential spot type sensor 110 The differential spot type sensor 110 emits a fire signal when the rate of increase in the ambient temperature in the fire monitoring area reaches a certain rate or more, and operates due to the heat effect of a local area.

[0026] The differential spot type sensor 110 has a structure in which a diaphragm provided in the housing 10 is pushed up by the expansion of air, and a fire signal is emitted by mechanically closing contacts. Furthermore, the differential spot type sensor 110 has a leak hole. Here, the diaphragm, the leak hole, and the contacts correspond to the components included in the sensing mechanism unit 20.

[0027] The sensing mechanism 20 is housed within the main body 12, which is part of the housing 10. The housing 10, which consists of the base 11 and the main body 12, is constructed by coating the surface of the plastic-free material 10a with resin 10b, as explained in Figure 2 above.

[0028] Figure 3 is a perspective view showing the internal structure of a differential spot-type detector 110 in Embodiment 1 of the present disclosure. Figure 3 illustrates a state in which the main body 12 is composed of a first main body 12a and a second main body 12b, and a sensing mechanism 20 for functioning as a differential spot-type detector 110 is housed within the main body 12.

[0029] The first main body portion 12a is configured to be detachable from the base portion 11, and when fitted with the second main body portion 12b, it forms a main body portion 12 having a space inside that can house the sensing mechanism portion 20.

[0030] Figure 3 shows a diaphragm 21 and a leak hole 22 as specific examples of the sensing mechanism 20.

[0031] Here, in the differential spot-type detector 110 shown in Figure 3, as shown in Figure 2, by using a housing 10 in which the surface of the plastic-free material 10a is coated with resin 10b, environmental issues can be taken into consideration, and heat resistance, durability, and waterproofing can be provided, taking into account the installation environment of the differential spot-type detector 110.

[0032] <2> When applying the structure of the housing 10 to the photoelectric spot-type detector 120 The photoelectric spot-type detector 120 has a light-emitting unit and a light-receiving unit installed inside a dark box with a shape that allows smoke from a fire to easily enter. When the amount of light received by the light-receiving unit, which is scattered by the smoke when the light emitted from the light-emitting unit is received by the light-receiving unit, exceeds a threshold value, it emits a fire signal and is activated by smoke.

[0033] Furthermore, the photoelectric spot-type detector 120 is equipped with a light-shielding plate to prevent light from the light-emitting part from being directly received by the light-receiving part. In addition, the photoelectric spot-type detector 120 is equipped with measures to prevent false alarms caused by natural light, external light from lighting fixtures, insects, etc.

[0034] The photoelectric spot-type detector 120 has a structure that determines that scattered light due to smoke generation has increased when the amount of light received by the light-receiving unit exceeds a threshold, and transmits a fire signal. Here, the light-emitting unit, light-receiving unit, and light-shielding plate correspond to components included in the detection mechanism unit 20.

[0035] The sensing mechanism 20 is housed within the main body 12, which is part of the housing 10. The housing 10, which consists of the base 11 and the main body 12, is constructed by coating the surface of the plastic-free material 10a with resin 10b, as explained in Figure 2 above.

[0036] Figure 4 is a perspective view showing the internal structure of a photoelectric spot-type detector 120 in Embodiment 1 of the present disclosure. Figure 4 illustrates a state in which the main body 12 is composed of a first main body 12a and a second main body 12b, and a sensing mechanism 20 for functioning as a photoelectric spot-type detector 120 is housed within the main body 12.

[0037] The first main body portion 12a is configured to be detachable from the base portion 11, and when fitted with the second main body portion 12b, it forms a main body portion 12 having a space inside that can house the sensing mechanism portion 20.

[0038] Figure 4 shows a specific example of the sensing mechanism 20, which includes a circuit board 23 on which electrical components are mounted, a light-emitting unit 24, and a light-shielding plate 25.

[0039] Here, in the photoelectric spot-type detector 120 shown in Figure 4, as shown in Figure 2, by using a housing 10 in which the surface of the plastic-free material 10a is coated with resin 10b, environmental issues can be considered, and heat resistance, durability, and waterproofing can be provided, taking into account the installation environment of the photoelectric spot-type detector 120.

[0040] As described above, according to Embodiment 1, by employing a housing in which the surface of a plastic-free material is coated with resin, it is possible to realize disaster prevention equipment that takes both environmental issues and installation environments into consideration.
