[0006] Technical issues

[0007] However, since the indicator light of the detector in Patent Document 1 is located next to a protector protruding from the housing (e.g., a part of a protective thermal resistor), the protector may obstruct the view depending on the direction in which the detector is observed. Therefore, it is necessary to strictly manage the installation direction of the detector according to predetermined standards (standards for detector installation, such as ensuring that the indicator light of the detector is visible from the entrance of the room where the detector is installed), which is a troublesome task.

[0008] The present invention was conceived in view of the above-mentioned problems, and its object is to provide a disaster prevention device that can improve the visibility of the luminous state.

The detection element performs physical quantity detection on the target.

[0011] The disaster prevention device of claim 2 is the disaster prevention device according to claim 1, wherein the detection element protector guides the light from the light emitter and emits the light.

[0012] According to one embodiment of the present invention, the disaster prevention device further includes: a light guide formed in at least a portion of the housing, and a light emitter causing the light guide to emit light.

[0013] According to one embodiment of the present invention, a light emitting surface of the light guide extends from a front side of the housing to a side side of the housing, and when viewed from the front side of the housing, the light emitting surface of the light guide has a linear shape or a curved shape.

[0014] According to one embodiment of the present invention, the light guide is positioned corresponding to an operating hole disposed in the housing, so as to operate the disaster prevention equipment.

[0015] According to one embodiment of the invention, the light emitter causes a thin-walled portion to emit light, the thin-walled portion being a part that is thinner than the rest of the housing.

[0016] According to one embodiment of the present invention, a light-emitting surface of the thin-walled portion extends from a front side of the housing to a side side of the housing, and when viewed from the front side of the housing, the light-emitting surface of the thin-walled portion has a linear shape or a curved shape.

[0024] According to one embodiment of the present invention, by guiding and emitting light from the light emitter through the detection element protector, the entire detection element protector can emit light, thereby improving the visibility of the luminous state.

[0025] According to one embodiment of the present invention, regarding the emission of light by the light guide, for example, since in addition to the detection element protector, the visibility of the luminous state can be further improved by emitting light by the light guide.

[0026] According to one embodiment of the invention, the light-emitting surface of the light guide extends from the front side of the housing to the side side of the housing, thus allowing reliable observation of the light emission state even from a position far from the disaster prevention equipment and where the front is difficult to see. Furthermore, when viewed from the front side of the housing, for example, the light-emitting surface of the light guide has a linear or curved shape, thereby improving the design flexibility of the disaster prevention equipment. In particular, when the light-emitting surface of the light guide is curved when viewed from the front side of the housing, for example, when the disaster prevention equipment is mounted on a ceiling, the area of ​​the light guide visible from the floor side is larger than when the light-emitting surface is linear.

[0027] According to one embodiment of the invention, the light guide is positioned corresponding to the operation hole, thus drawing the user's attention to the light guide side, making the operation hole less conspicuous.

[0028] According to one embodiment of the present invention, for example, by making the thin-walled portion emit light, it is not necessary to use other components such as light guides, thus reducing the number of components and thereby reducing costs.

[0029] According to one embodiment of the present invention, the light-emitting surface of the thin-walled portion extends from the front side of the housing to the side side of the housing, so that the luminescence state can be reliably observed even from a position, for example, far from the disaster prevention equipment and where the front is difficult to see.

When multiple disaster prevention devices are installed, the impression of uneven pointing of the light-emitting surface can be reduced.

[0030] According to one embodiment of the present invention, since the disaster prevention device is at least a thermal detector, it is possible to provide, for example, a thermal detector that allows observation of the luminescence state from all directions.

[0031] According to one embodiment of the present invention, for example, by emitting light through the light guide, the visibility of the luminous state can be further improved. Furthermore, since the light-emitting surface of the light guide extends from the front side of the housing to the side side of the housing, the luminous state can be reliably observed even from a location, for example, far from the disaster prevention equipment and where the front is difficult to see.

[0032] According to one embodiment of the invention, when viewed from the front side of the housing, for example, the light-emitting surface of the light guide has a linear or curved shape, thus improving the design flexibility of the disaster prevention equipment. In particular, when the light-emitting surface of the light guide is curved when viewed from the front side of the housing, for example, when the disaster prevention equipment is mounted on the ceiling, the area of ​​the light guide visible from the floor side is larger than when the light-emitting surface is linear. Furthermore, when multiple disaster prevention devices are installed, the impression of uneven pointing of the light-emitting surface can be reduced.

[0033] According to one embodiment of the present invention, for example, by emitting light from the thin-walled portion, the visibility of the luminous state can be further improved. Furthermore, since other components such as light guides are not required, the number of components can be reduced, thereby lowering costs. Additionally, since the light-emitting surface of the thin-walled portion extends from the front side of the housing to the side side of the housing, the luminous state can be reliably observed even from locations, for example, far from disaster prevention equipment and where the front is difficult to see.

[0074] Hereinafter, specific embodiments of the disaster prevention device of the present invention will be described in detail with reference to the accompanying drawings. Incidentally, the present invention is not limited to these embodiments.

[0075] [Basic Concepts of the Implementation Examples]

[0076] First, the basic concepts of specific embodiments will be described. These embodiments generally relate to disaster prevention equipment.

[0077] "Disaster prevention equipment" is equipment used to avoid disasters. For example, it is a concept that includes equipment for detecting and monitoring anomalies in areas such as heat detectors, fire detectors, gas detectors, and smoke detectors. In addition, "disaster prevention equipment" includes, for example, a housing and a light emitter, and optionally includes a light guide and a thin-walled part.

[0078] "Monitoring area" refers to the area monitored by disaster prevention equipment. Specifically, it is a certain range of space, including, for example, rooms (e.g., Room A on the 1st floor, Room B on the 1st floor), corridors, building staircases, etc. "Monitoring area anomaly" refers to a situation where the monitored area's condition differs from its normal state. Specifically, this includes situations such as a fire or gas leak.

[0079] "Outer shell" is, for example, at least some components that cover disaster prevention equipment.

[0080] A "light emitter" is a unit that outputs information by causing at least a portion of a disaster prevention device to emit light. A concept for this unit includes one that causes a detection element protector to emit light, whereby the protector houses a detection element that protrudes from its housing, and the detection element performs physical quantity detection on the target. Alternatively, a "light emitter" can also be a unit that causes a light guide to emit light, or a unit that causes a thin-walled portion to emit light. Incidentally, for example, the object of light emission caused by the light emitter can be only one of the detection element protector, the light guide, and the thin-walled portion, it can be two of them, or it can be all of them.

[0081] "The physical quantity of the target being detected" is a quantity that is generated or changed due to anomalies in the monitored area, such as the concepts of temperature caused by heat, smoke concentration, and the concentration of gases such as carbon monoxide. "Detection element" is a component that detects the physical quantity of the target being detected. Examples of its concepts include thermal sensors such as thermal resistors, smoke sensors composed of light-emitting diodes, photodiodes, etc., and gas sensors.

[0082] "Detection element protector" is a device that houses a detection element. Specifically, it includes a detection element protector that protrudes from a housing or the like. For example, it includes a detection element protector that guides light from a light emitter and emits light. As another example, it includes a thermal resistance protector that protects a thermal resistor or the like.

[0083] A "light guide" is formed in at least a portion of the housing. The concept includes, for example, a light guide that guides and emits light, and a structure in which the light-emitting surface of the light guide extends from the front side of the housing to the side side of the housing. The concept also includes a structure in which the light-emitting surface of the light guide has a linear or curved shape when viewed from the front side of the housing. Furthermore, the concept includes a light guide positioned at a location corresponding to an operating hole in the housing for operating the disaster prevention equipment. Incidentally, "operating the disaster prevention equipment" includes, for example, a situation where a user actually operates the disaster prevention equipment; as an example, this includes a situation where the disaster prevention equipment is rotated relative to the mounting part while a predetermined clamp is inserted into the operating hole. Additionally, the concept of "the light-emitting surface of the light guide" includes, for example, a surface of the light guide that is exposed outside the disaster prevention equipment and visible to the user.

[0084] "Thin-walled section" refers to a portion of the outer casing that is relatively thinner than other parts. For example, it can be a section that is thin enough to transmit at least a portion of the irradiated light, or a section whose light-emitting surface extends from the front side of the outer casing to the side side, or a section whose light-emitting surface is linear or curved when viewed from the front side of the outer casing. Here, "light-emitting surface of thin-walled section" is defined as a portion of the thin-walled section through which light emitted from the light emitter passes and which is exposed outside the disaster prevention equipment, i.e., the surface area from which the user observes the light emission.

[0085] Furthermore, in the specific embodiments shown below, the case where the "disaster prevention device" is a thermal detector will be described, and in particular, in the first embodiment, the case where the detection element protector and the light guide emit light will be described. In the second embodiment, the case where the detection element protector and the thin-walled portion emit light will be described.

[0086] [Details of the Implementation Examples]

[0087] The specific details of the embodiments will be described below.

[0088] (First Embodiment)

[0089] First, the first embodiment will be described. In this embodiment, the situation where the detection element protector and the light guide emit light will be described.

[0090] (Configuration - Detector)

[0091] First, the structure of the detector in this embodiment will be described. Figure 1 This is a perspective view of the detector according to a specific embodiment of the present invention. Figure 2 This is a plan view of the detector. Figure 3 This is a side view of the detector. Figure 4 It is along Figure 2 A sectional view with section line AA. Incidentally, in each drawing, the Z-axis and the X and Y axes orthogonal to the Z-axis will be described as representing the vertical and horizontal directions, respectively. Furthermore, terms such as "front," "rear," and "side" will be used to describe components of detector 100. Specifically, when detector 100 is mounted on the connecting object 900, which is a ceiling surface, the portion of detector 100 located on the floor surface side (relative to the side of detector 100 opposite to the connecting object 900) Figure 3 The -Z direction) is referred to as the "front part", while the part of the detector 100 relative to the connected object 900 as the ceiling surface ( Figure 3 The area in the +Z direction is referred to as the "rear part". Additionally, the outer peripheral surface of the detector 100, which is connected to both the "front part" and the "rear part", is the "side part". Incidentally, the definitions of "front part", "rear part", and "side part" are the same in the second embodiment.

[0092] Figures 1 to 4 Detector 1 in each figure is a disaster prevention device; specifically, it is a thermal detector that detects heat. Figure 3 The connection portion 101 of the detector 100 (e.g., a so-called "detector base," the detailed structure of which is not shown) is mounted on the connection object 900, which is, for example, a ceiling surface. As an example, the detector 100 includes... Figure 1 The outer casing 11, the protective part 12 and the protective part 13, and Figure 4 The thermal resistor 14 and the light emitter 15.

[0093] (Configuration - Detector - Housing)

[0094] Figure 1 The housing 11 covers at least a portion of the components of the detector 100. The specific type or configuration of the housing 11 can be any type or configuration; however, for example... Figure 3As shown, the housing 11 includes a cylindrical portion whose diameter remains constant as it extends away from the connecting portion 101, and a tapered portion whose diameter decreases as it extends away from the connecting portion 101. It has light-shielding properties (except for certain portions) and includes... Figure 2 The light guide 111 and the operation hole 112. Incidentally, "light blocking" is the ability to block light, and its concept, for example, refers to the ability of the housing 11 to prevent light from passing through from the inside to the outside.

[0095] The light guide 111 is the aforementioned light guide. The specific type or configuration of the light guide 111 can be arbitrary; however, for example, the light guide 111 is formed within a portion of the housing 11 and can be made of any material to function as a light guide for guiding and emitting light. The light guide 111 is formed separately from the light-shielding portion of the housing 11 and allows light to pass through from the interior of the housing 11 to the exterior. Furthermore, in the light guide 111, for example, the light-emitting surface of the light guide 111 (exposed to…) Figure 2 and Figure 3 The outer surface of the detector 100 shown extends from the front side (-Z direction) of the housing 11 to the side side (+X direction or -X direction) of the housing 11, as... Figure 2 As shown, two light guides 111 are provided. When viewed from the front side of the housing 11, the light emitting surface of the light guide 111 is linear in shape, and the light guide 111 is positioned corresponding to the operation hole 112.

[0096] The operating hole 112 is the aforementioned operating hole. The specific type or configuration of the operating hole 112 can be any type or configuration; however, the operating hole 112 is, for example, a hole communicating with the interior of the housing 11, so that the aforementioned predetermined clamp can be inserted therein.

[0097] (Configuration - Detector - Protection Unit)

[0098] Figure 1 The protective portion 12 is the aforementioned protector for the detection element. The specific type or configuration of the protective portion 12 can be any type or configuration; however, for example, the protective portion 12 is formed within a part of the housing 11 and can be made of any material to function as a light guide for directing and emitting light, formed separately from the light-shielding portion of the housing 11, and allowing light to pass through the housing 11 from the inside out. Additionally, for example, the protective portion... Figure 4 The protective portion 12 of the thermal resistor 14 has a hollow portion for housing the thermal resistor 14. The protective portion 12 protrudes from the housing 11 to the opposite side (-Z direction) of the mounting portion 101, is disposed at the center of the housing 11 along the widening direction of the housing 11 (parallel to the XY plane), and is integrally formed with the light guide portion 111. Furthermore, the protective portion 12 includes, for example, […]. Figure 1 The frame portion 121 and the opening portion 122, and Figure 4The beam splitter 123.

[0099] The frame portion 121 is, for example, a portion that forms at least a part of the shape of the protective portion 12, and is a portion that includes a circular member and six support members. The circular member forms the front end portion (-Z direction) of the detector 100, and the support members are located between the circular member and the housing 11 and support the circular member.

[0100] The opening 122 is, for example, the part where hot air enters and exits the thermal resistor 14 relative to the hollow part of the protective part 12. Six openings 122 are provided and separated by the six support members of the frame part 121.

[0101] The beam splitter 123 is, for example, the part that refracts, disperses, or reflects the light output from the light emitter 15, and is the part facing the light emitter 15.

[0102] (Configuration - Detector - Protection Unit)

[0103] Figure 1 The protective part 13 is a protector that prevents a contact object from contacting the thermal resistor 14 housed in the protective part 12. Incidentally, "contact object" is an object that the protective part 13 prevents from being touched; the concept of a contact object includes, for example, a user's finger. The specific type or configuration of the protective part 13 can be any type or configuration; however, the protective part 13 is, for example, a protrusion provided in the opening 122.

[0104] (Configuration - Detector - Thermoresistor)

[0105] Figure 4 The thermal resistor 14 is the aforementioned sensing element. The specific type or configuration of the thermal resistor 14 is any type or configuration; however, the thermal resistor 14 detects temperature, for example, caused by heat or hot airflow. The protruding direction of the thermal resistor 14 is orthogonal to the width direction (Z-axis direction) of the housing 11, and the thermal resistor 14 is housed within the protective portion 12.

[0106] (Configuration - Detector - Light Emitter)

[0107] Figure 4 The light emitter 15 is the light emitter described above. The specific type or configuration of the light emitter 15 is any type or configuration; however, for example, the light emitter 15 causes the light guide 111 and the protection 12 to emit light and outputs the light to the beam splitter 123, and the light emitter 15 may be composed of a light-emitting diode or the like.

[0108] (Emission of light)

[0109] Next, the emitted light of the detector 100 thus configured will be described. Incidentally, the detector 100 can emit light at any time, for example, when the status of the detector 100 is notified at any time, or assuming that the detector 100 determines a fire has occurred based on the heat temperature detected by the thermal resistor 14. Incidentally, since the same process as in related art applies to the process by which the detector 100 determines a fire, its description will not be repeated. Figure 5 It is as shown Figure 4 Example diagram of the light path.

[0110] Figure 5 The control unit (not shown) of the detector 100 causes the light emitter 15 to output light. At this time, the light guide 111 and the protection part 12 are integrally formed, as shown. Figure 5 As shown, light from the light emitter 15 is refracted, dispersed, or reflected by the beam splitter 123, and then guided to the light guide 111 and the protective part 12, which are integrated as a whole. Incidentally, for ease of description, in... Figure 5 Only the light path from the light emitter 15 on the left side of the diagram is shown, but in reality, light also exits from the light emitter 15 on the right side of the diagram and is then guided to the light guide section 111 and the protection section 12, which are integrated as a whole. Therefore, Figure 1 The light guide 111 and the protective part 12, which are integrated as a whole, emit light. Because the light is emitted in this way, the light emitted from the detector 100 can be observed from any position in the room where the detector 100 is installed.

[0111] (Effects of the Example)

[0112] According to this embodiment, in this way, for example by causing the protective portion 12 protruding from the housing 11 to emit light, the visibility of the luminous state can be improved. In particular, the luminous state can be observed from any direction, for example.

[0113] Furthermore, for example, by guiding and emitting light from the light emitter 15, the entire protective section 12 can emit light, thereby improving the visibility of the emitting state.

[0114] Furthermore, regarding the light guide 111 emitting light, for example, since the light guide 111 can also emit light in addition to the protective part 12, the visibility of the emitting state is further improved.

[0115] Furthermore, the light guide 111 extends from the front side of the housing 11 to the side side of the housing 11, so the light emission state can be reliably observed even from a position far from the detector 100 and where the front is difficult to see. In addition, when viewed from the front side of the housing 11, for example, the light emitting surface of the light guide 111 has a linear shape, which improves the design flexibility of the detector 100.

[0116] In addition, the light guide 111 is positioned corresponding to the operation hole 112, which draws the user's attention to the light guide 111 side, making the operation hole 112 less conspicuous.

[0117] (Second Embodiment)

[0118] Next, a second embodiment will be described. In this embodiment, the case of light emission from the detection element protector and the thin-walled portion will be described. Incidentally, unless otherwise stated, it is assumed that each configuration of the second embodiment is equivalent to each configuration with the same name in the first embodiment.

[0119] (Configuration - Detector)

[0120] First, the structure of the detector in this embodiment will be described. Figure 6 This is a perspective view of the detector according to a specific embodiment of the present invention. Figure 7 This is a plan view of the detector. Figure 8 This is a side view of the detector. Figure 9 It is along Figure 7 The cross-sectional view of section line BB. The detector 200 in each figure is a disaster prevention device, specifically a heat detector for detecting heat, through... Figure 8 The connector 201 of the detector 200 is mounted on the connected object 900, which is, for example, a ceiling surface. As an example, the detector 200 includes... Figure 6 The outer casing 21, the protective part 22 and the protective part 23, and Figure 9 The thermal resistor 24 and the light emitter 25.

[0121] (Configuration - Detector - Housing)

[0122] Figure 6 The housing 21 covers at least a portion of the components of the detector 200. The specific type or configuration of the housing 21 can be any type or configuration; however, for example, the housing 21 may block all or only a portion of the light and include... Figure 7 The thin-walled portion 211.

[0123] The thin-walled portion 211 is a portion that is thinner than the other portions of the housing 21. The specific type or configuration of the thin-walled portion 211 is any type or configuration; however, the thin-walled portion 211 is, for example, thin enough to transmit at least a portion of the irradiated light (i.e., thin enough to block only a portion of the irradiated light), and is integrally formed with the other portions of the housing 21. The light-emitting surface of the thin-walled portion 211 (exposed to...) Figure 7 and Figure 8The outer surface of the detector 200 (for ease of explanation, the portion enclosed by dashed lines) extends from the front side (-Z direction) of the housing 21 towards the side side (+X direction or -X direction) of the housing 21. Two thin-walled portions 211 are provided, such as... Figure 7 As shown, when viewed from the front side of the housing 21, the light-emitting surface of the thin-walled portion 211 has a linear shape.

[0124] Incidentally, "other parts of the housing 21" are a part of the housing 21, specifically the parts of the housing 21 other than the thin-walled portion 211, such as the portion that is thick enough to block virtually all the irradiated light.

[0125] (Configuration - Detector - Protection Unit)

[0126] Figure 6 The protective portion 22 is the aforementioned protector for the detection element. The specific type or configuration of the protective portion 22 can be any type or configuration; however, for example, the protective portion 22 is formed within a part of the housing 21 and can be made of any material to function as a light guide for directing and emitting light. The protective portion 22 is formed separately from the light-shielding portion of the housing 21 and allows light to pass through from the interior of the housing 21 to the exterior. Additionally, the protective portion 22, for example, protects... Figure 9 The thermal resistor 24 and the protection part 22 include, for example, the thermal resistor 24 and the protection part 22. Figure 6 The frame portion 221 and the opening portion 222, and Figure 9 The beam splitter 223. Incidentally, the structure of the frame portion 221, the opening portion 222, and the beam splitter 223 is the same as that of the counterpart with the same name in the first embodiment, so their description is omitted.

[0127] (Configuration - Detector - Protective Unit, Thermal Resistance, Light Emitter)

[0128] because Figure 6 Protective Department 23 and Figure 9 The configuration of the thermal resistor 24 and the light emitter 25 is the same as that of the one with the same name in the first embodiment, so its description will not be repeated.

[0129] (Emission of light)

[0130] Next, the emitted light of the detector 200 configured in this way will be explained. Figure 10 It is as shown Figure 9 Example diagram of the light path.

[0131] Figure 10 The control unit (not shown) of the detector 200 causes the light emitter 25 to output light. In this case, the light from the light emitter 25 is refracted, dispersed, or reflected by the beam splitter 223, such as... Figure 10As shown, light illuminates the entire thin-walled portion 211 and is guided to the entire protective portion 22. Incidentally, for ease of description, in... Figure 10 Only the light path from the light emitter 25 on the left side of the figure is shown, but in reality, light also exits from the light emitter 25 on the right side of the figure, illuminating the entire thin-walled portion 211 and being guided to the entire protective portion 22. Then, Figure 7 The thin-walled portion 211 and the protective portion 22 emit light as a whole. Because light is emitted in this way, the light emitted from the detector 200 can be observed from any location in the room where the detector 200 is installed.

[0132] (Effects of the Example)

[0133] In this way, according to this embodiment, for example, by making the thin-walled portion 211 emit light, it is not necessary to use other components such as light guides, thus reducing the number of components and lowering costs.

[0134] Furthermore, the light-emitting surface of the thin-walled portion 211 extends from the front side of the housing 21 to the side side of the housing 21, so the light emission state can be reliably observed even from a position far from the detector 200 and where the front is difficult to see. In addition, for example, when viewed from the front side of the housing 21, the light-emitting surface of the thin-walled portion 211 has a linear shape, thus improving the design flexibility of the detector 200.

[0135] [Example of a modified embodiment]

[0136] The specific embodiments of the present invention have been described above. However, within the scope of the technical concepts of the inventions described in the claims, any changes or improvements can be made to the specific structure, units, and parts of the present invention. Such modifications will be described below.

[0137] (Regarding technical issues and the effects of the invention)

[0138] First, the technical problems and effects of the present invention are not limited to the above-mentioned contents, and may vary depending on the implementation environment or configuration details of the present invention. Furthermore, it may only solve some of the above-mentioned problems, or only obtain some of the above-mentioned effects.

[0139] (On separation and integration)

[0140] Furthermore, the above configuration is conceptual and does not necessarily require the physical configuration shown in the figures. That is, the specific ways in which the parts are separated and integrated are not limited to those shown in the figures, and they can be configured, in whole or in part, to be functionally or physically separated or integrated in any unit.

[0141] (Regarding the light-conducting section and the thin-walled section)

[0142] Additionally, in the first embodiment, as Figure 2 As shown, the case where the light-emitting surface of the light guide 111 is linear when viewed from the front side of the housing 21 has been described, but the present invention is not limited thereto. Figure 11 This is a plan view of the detector. (For example...) Figure 11 Like the light guide section 311 of the detector 300, when viewed from the front side of the housing 21, the light emitting surface of the light guide section 311 (exposed to the light) Figure 11 The outer surface of the detector 300 shown can also be curved (e.g., integrally S-shaped). Furthermore, similarly, in the second embodiment... Figure 7 The thin-walled portion 211 may also have a curved shape (e.g., S-shaped overall).

[0143] Furthermore, while the above specific embodiments described a case where two light guide portions and two thin-walled portions are provided, the present invention is not limited thereto. For example, one light guide portion and one thin-walled portion may be provided, or three or more light guide portions and three or more thin-walled portions may be provided. Alternatively, the light guide portions and thin-walled portions may be omitted. Additionally, the number or configuration of the light emitters corresponding to the protective portion, light guide portion, and thin-walled portion is arbitrary.

[0144] (Regarding the luminous object of the light emitter)

[0145] Furthermore, in specific embodiments, for causing Figure 2 Protection section 12 and Figure 7 The situation where the protective portion 22 emits light has been described, but the present invention is not limited thereto. For example, each of the protective portions 12 and 22 can be formed by a member having light-shielding properties, such that only light is emitted by the protective portion 22. Figure 2 Light guide section 111 and Figure 7 The thin-walled portion 211 can be configured to emit light from the light emitters 15 and 25.

[0146] (Regarding disaster prevention equipment applicable to various shapes)

[0147] Furthermore, the technologies described in the various embodiments or modifications can also be applied to various disaster prevention devices. As an example, these technologies can be applied to smoke detectors of various shapes. Specifically, these technologies can be applied to smoke detectors where a smoke detection unit is housed within a portion of the housing (hereinafter referred to as a first smoke detector), or to smoke detectors where the housing is entirely disc-shaped and flat, and the smoke detection unit is housed within the flat housing without protrusions (hereinafter referred to as a second smoke detector). Additionally, when applying these technologies to a first smoke detector, similar to the cases described in each embodiment, the protrusion can serve as a protector for the light-emitting detection element, or a structure can be adopted that allows a light guide or thin-walled portion disposed therein to emit light. Furthermore, when applying these technologies to a second smoke detector, since there is no protrusion and no corresponding protection for the detection element is provided, a structure can be adopted that only provides one or both of the light guide and the thin-walled portion, and allows the light guide or thin-walled portion to emit light. Moreover, the concepts described herein can be applied to any disaster prevention device other than smoke detectors.

[0148] (Regarding characteristics)

[0149] Furthermore, the structural features and variations of each specific embodiment can be combined arbitrarily. For example, Figure 2 The detector 100 can be configured such that the thin-walled portion is disposed in the housing 11 and that the thin-walled portion emits light together with the light guide portion 111, or, Figure 7 The detector 200 can also be configured to have a light guide on the housing 11, and to emit light together with the thin-walled portion 211. In this case, the configuration or number of both can be arbitrary.

In particular, the luminous state can be observed from any direction, for example.

[0165] According to the disaster prevention device described in Note 2, by guiding the light from the light emitter to the detection element protector and emitting light, the detection element protector as a whole can emit light, thereby improving the visibility of the luminous state.

[0166] According to the disaster prevention equipment described in Note 3, regarding the emission of light by the light guide, for example, since in addition to the detection element protector, the visibility of the luminous state can be further improved by emitting light through the light guide.

[0167] According to the disaster prevention device described in Note 4, the light-emitting surface of the light guide extends from the front side of the housing to the side side of the housing, so the light emission state can be reliably observed even from a position far from the disaster prevention device and where the front is difficult to see. Furthermore, for example, when viewed from the front side of the housing, the light-emitting surface of the light guide has a linear or curved shape, thus improving the design flexibility of the disaster prevention device. In particular, when the light-emitting surface of the light guide is curved when viewed from the front side of the housing, for example, when the disaster prevention device is mounted on the ceiling, the area of ​​the light guide visible from the floor side is larger than when the light-emitting surface is linear.

[0168] According to the disaster prevention device described in Note 5, the light guide is positioned corresponding to the operation hole, so that, for example, the user's attention can be drawn to the light guide side, making the operation hole less conspicuous.

[0169] According to the disaster prevention equipment described in Note 6, for example, by emitting light from the thin-walled portion, other components such as light guides are not required, thus reducing the number of components and thereby reducing costs.

[0170] According to the disaster prevention device described in Note 7, the light-emitting surface of the thin-walled section extends from the front side of the housing to the side side of the housing, so the luminescence state can be reliably observed even from a position far from the disaster prevention device and where the front is difficult to see. Furthermore, when viewed from the front side of the housing, the linear or curved shape of the light-emitting surface of the thin-walled section improves the design flexibility of the disaster prevention device. In particular, when the light-emitting surface of the thin-walled section is curved when viewed from the front side of the housing, for example, when the disaster prevention device is mounted on the ceiling, the area of ​​the light guide visible from the floor side is larger than when the light-emitting surface is linear. When multiple disaster prevention devices are installed, the impression of uneven pointing of the light-emitting surface can be reduced.

[0171] According to the disaster prevention equipment described in Note 8, since the disaster prevention equipment is at least a thermal detector, it is possible to provide, for example, a thermal detector that can observe the luminescence state from all directions.

[0172] According to the disaster prevention equipment described in Note 9, for example, by emitting light through a light guide, the visibility of the luminous state can be further improved. In addition, since the light emitting surface of the light guide extends from the front side of the housing to the side side of the housing, the luminous state can be reliably observed even from a position, for example, far from the disaster prevention equipment and where the front is difficult to see.

[0173] According to the disaster prevention equipment described in Note 10, the light-emitting surface of the light guide has a linear or curved shape when viewed from the front side of the housing, thus improving the design flexibility of the disaster prevention equipment. In particular, when the light-emitting surface of the light guide is curved when viewed from the front side of the housing, for example, when the disaster prevention equipment is mounted on the ceiling, the area of ​​the light guide visible from the floor side is larger than when the light-emitting surface is linear. When multiple disaster prevention devices are installed, the impression of uneven pointing of the light-emitting surface can be reduced.

[0174] According to the disaster prevention equipment described in Note 11, for example, by emitting light from the thin-walled portion, the visibility of the luminous state can be further improved. Furthermore, since other components such as light guides are not required, the number of components can be reduced, thereby lowering costs. Additionally, since the light-emitting surface of the thin-walled portion extends from the front side of the housing to the side side of the housing, the luminous state can be reliably observed even from positions, such as those far from the disaster prevention equipment and where the front is difficult to see.

[0175] According to the disaster prevention equipment described in Note 12, for example, when viewed from the front side of the housing, the light-emitting surface of the thin-walled portion has a linear or curved shape, thus improving the design flexibility of the disaster prevention equipment. In particular, when the light-emitting surface of the thin-walled portion is curved when viewed from the front side of the housing, for example, when the disaster prevention equipment is mounted on the ceiling, the range of the light guide visible from the floor side is greater than when the light-emitting surface is linear. When multiple disaster prevention devices are installed, the impression of uneven pointing of the thin-walled portion can be reduced.
