Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments of the disaster prevention equipment according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited by the embodiments.

[0013] 〔Basic Concept of the Embodiment〕 First, the basic concept of the embodiment will be described. The embodiment is generally related to disaster prevention equipment.

[0014] "Disaster prevention equipment" is equipment used for disaster prevention, and includes, for example, equipment for detecting abnormalities in a monitoring area, etc. As an example, it includes concepts such as thermal sensors, fire sensors, gas sensors, and smoke sensors. Also, "disaster prevention equipment" includes, for example, an outer cover, a detection element, detection element protection means, and prevention means.

[0015] "Monitoring area" is the area targeted for monitoring by disaster prevention equipment, specifically, a space with a certain extent, and includes, for example, concepts such as rooms in a building (e.g., Room A on the first floor, Room B on the first floor, etc.), corridors, stairs, etc. Also, "abnormality in the monitoring area" means that the state of the monitoring area is different from normal, and specifically includes concepts such as fire occurrence, gas leakage, etc. <000009o> "Outer cover" is, for example, something that covers at least a part of the components of the disaster prevention equipment.

[0017] The "detection element" is, for example, a component for detecting a physical quantity to be detected. As an example, it is a concept including temperature sensors such as thermistors, smoke sensors composed of light-emitting diodes and photodiodes, and gas sensors. The "physical quantity to be detected" is, for example, a quantity that can be generated or changed due to an abnormality in the monitoring area. As an example, it is a concept including temperature due to heat, smoke concentration, concentration of carbon monoxide gas, etc. Here, the "detection target" is, for example, a hot air flow when the physical quantity to be detected is heat (temperature), an air flow containing smoke particles when the physical quantity to be detected is smoke concentration, an air flow containing carbon monoxide gas when the physical quantity to be detected is gas concentration, for example, carbon monoxide gas concentration, etc.

[0018] The "detection element protection means" is something that houses the detection element. Specifically, it is provided on the outer cover and is a concept including those having an opening through which the detection target flows in or out toward the detection element. Specifically, for example, a thermistor guard that protects the thermistor while allowing a hot air flow to flow in from the outside toward the thermistor as a detection element provided in a heat detector and flowing out from the thermistor side to the outside, or for example, a smoke sensor guard part or a smoke sensor housing cover part that protects the smoke detection part while allowing an air flow containing smoke particles to flow in from the outside to the smoke detection part as a smoke sensor provided in a smoke detector through a smoke inflow / outflow port which is an opening and flowing out from the smoke detection part to the outside.

[0019] The "prevention means" is a means for preventing a contact target from contacting the detection element, and is provided at the opening of the detection element protection means. Specifically, it is a protrusion. Also, the "prevention means" is a concept including, for example, those protruding from the outer cover side, those provided at a position closer to the center at the edge of the opening, those having a curved outer surface in the prevention means, and those provided with at least one for a plurality of openings.

[0020] Furthermore, "contact target" refers to an object whose contact with the detection element is prevented by preventative measures, and this concept includes, for example, the user's finger.

[0021] The following embodiment describes the case where the "disaster prevention equipment" is a heat detector.

[0022] [Specific details of the embodiment] Next, the specific details of the embodiment will be described.

[0023] (Configuration-sensor) First, the configuration of the detector according to this embodiment will be described. Figure 1 is a perspective view of the detector according to an embodiment of the present invention, Figure 2 is a plan view of the detector, Figure 3 is a side view of the detector, and Figure 4 is a cross-sectional view taken along line A-A in Figure 2. In each figure, the Z-axis represents the vertical direction, and the X-axis and Y-axis, which are perpendicular to the Z-axis, represent the horizontal direction. The detector 1 in each figure is a fire prevention device, specifically a heat detector that detects heat, and is attached to an object to be mounted 900 such as a ceiling via the mounting part 101 (detailed structure not shown) of the detector 100 in Figure 3. For example, it comprises the outer cover 11, protective part 12, and prevention part 13 in Figure 1, and the thermistor 14 and light-emitting part 15 in Figure 4.

[0024] (Configuration - Detector - Outer cover) The outer cover 11 in Figure 1 covers at least a portion of the components of the sensor 100. The specific type and configuration of this outer cover 11 are arbitrary, but for example, as shown in Figure 3, it has a cylindrical portion that has the same diameter even when away from the mounting portion 101 and a tapered portion that becomes smaller in diameter as it moves away from the mounting portion 101, and it has light-shielding properties except for the parts that are not specifically mentioned, and it has the light guide portion 111 shown in Figure 2. Note that "light-shielding properties" refers to the ability to block light, and is a concept that indicates, for example, the ability of the outer cover 11 not to allow light to pass from the inside to the outside.

[0025] The light guide section 111 is a light guiding means that guides light and emits light. The specific type and configuration of this light guide section 111 are arbitrary, but for example, it is formed in part of the outer cover 11, and is made of any material in order to function as a light guide that guides light and emits light, and is formed separately from the light-shielding part of the outer cover 11, and allows light to pass from the inside to the outside of the outer cover 11. Furthermore, the light guide section 111 extends from the front side (-Z direction) to the side side (+X direction or -X direction) of the outer cover 11, and there are two of them, and as shown in Figure 2, it is linear in shape.

[0026] (Configuration - Sensor - Protection part) The protective part 12 in Figure 1 is the aforementioned means for protecting the detection element. The specific type and configuration of this protective part 12 are arbitrary, but for example, it is formed on a part of the outer cover 11, and is made of any material to function as a light guide that guides light and emits light, and is formed separately from the light-shielding part of the outer cover 11, and allows light to pass from the inside to the outside of the outer cover 11. Furthermore, the protective part 12 is a so-called thermistor guard that protects the thermistor 14 in Figure 4, and has a hollow part for housing the thermistor 14, protrudes from the outer cover 11 toward the opposite side of the mounting part 101 (-Z direction), and is provided in the center of the outer cover 11 in the direction in which the outer cover 11 is spreading (parallel to the XY plane), and is formed integrally with the light guide part 111. Furthermore, the protective part 12 includes, for example, the frame part 121 in Figure 1, the opening 122, and the spectral part 123 in Figure 4.

[0027] Figure 5 is an enlarged view of a part of Figure 3. The frame portion 121 shown in Figure 5 is, for example, a part that forms the outer shape of at least a part of the protective portion 12, and also comprises a single circular member 121A that forms the tip portion (-Z direction) of the sensor 100, and six support members 121B that support the circular member 121A between the circular member 121A and the outer cover 11.

[0028] The opening 122 is, for example, a portion that allows hot air to flow in or out of the thermistor 14 shown in Figure 4, which is provided in the hollow portion of the protective part 12, and is also a portion that is divided into six sections by the six support members 121B shown in Figure 5 of the frame part 121.

[0029] The spectral section 123 in Figure 4 is, for example, a part that refracts, disperses, or reflects the light output from the light-emitting section 15, and is also a part that faces the light-emitting section 15.

[0030] (Configuration - Sensor - Prevention part) The prevention part 13 in Figure 1 is a means of preventing the user's finger, which is the object to be contacted, from coming into contact with the thermistor 14 housed in the protective part 12. The specific type and configuration of this prevention part 13 are arbitrary, but for example, it may be a projection provided in the opening 122, or it may protrude from the outer cover 11 side as shown in Figure 5, or it may be provided at a position closer to the center on the edge of the opening 122, or as shown in Figure 2, one for each opening 122, for a total of six. Furthermore, the outer surface 131 of the prevention part 13 in Figure 5 is curved, and more specifically, in the direction in which the outer cover 11 is spreading (parallel to the XY plane), as you move from the outside to the inside of the sensor 1, it curves in the height direction (Z axis direction) so that it approaches the circular member 121A side (-Z direction) (i.e., the distance from the outer cover 11 increases).

[0031] The size of the protective portion 13 and the opening 122 is arbitrary, but for example, it should be determined so as to prevent the user's finger from entering the hollow portion of the protective portion 12 through the opening 122 and coming into contact with the thermistor 14, while considering the inflow and outflow of hot airflow to the thermistor 14 side of the hollow portion of the protective portion 12. In this case, the size of the user's finger may be assumed to be a predetermined size, or it may be assumed to be the size of a predetermined test finger.

[0032] (Configuration - Sensor - Thermistor) The thermistor 14 in Figure 4 is the detection element described above. The specific type and configuration of this thermistor 14 are arbitrary, but for example, it detects temperature due to heat or hot airflow, and it protrudes in a direction perpendicular to the direction in which the outer cover 11 is expanding (Z-axis direction), and is housed in the protective part 12.

[0033] (Configuration - Sensor - Light-emitting part) The light-emitting unit 15 in Figure 4 is the aforementioned light-emitting means. The specific type and configuration of this light-emitting unit 15 are arbitrary, but for example, it may cause the light guide unit 111 and the protective unit 12 to emit light, or it may output light toward the spectral unit 123, or it may be configured using a light-emitting diode or the like.

[0034] (Preventing contact) Next, we will explain how to prevent a user's finger from coming into contact with the thermistor 14 of the detector 100 configured in this way. It is assumed that a user may hold the detector 100 in their hand while working on it at any time, such as during installation. In this case, if the user's finger attempts to enter the hollow part of the protective part 12 through the opening 122 in Figure 5, it will come into contact with the prevention part 13 provided in the opening 122. As a result, the user's finger is stopped by the prevention part 13, preventing it from coming into contact with the thermistor 14. Therefore, it is possible to prevent damage to the thermistor 14 due to contact. In addition, it is possible to prevent electrostatic discharge damage caused by the user's finger coming into close proximity to the thermistor.

[0035] (Luminous) Next, the light emission from the detector 100 configured in this way will be explained. The timing of the light emission from the detector 100 is arbitrary; for example, it may occur when the status of the detector 100 is reported, or when the detector 100 determines that there is a fire based on the temperature of the heat detected by the thermistor 14. The process by which the detector 100 determines that there is a fire can be the same as the conventional process, so its explanation will be omitted. Figure 6 is a diagram illustrating the optical path in Figure 4.

[0036] A control unit (not shown) of the sensor 100 in Figure 6 outputs light from the light-emitting unit 15. In this case, the light from the light-emitting unit 15 is refracted, dispersed, or reflected by the spectral unit 123 and guided to the entire light guide unit 111 and protective unit 12, as shown in Figure 6. Note that in Figure 5, for the sake of explanation, only the optical path of the light from the light-emitting unit 15 on the left side of the drawing is shown, but in reality, light is also output from the light-emitting unit 15 on the right side of the drawing and guided to the entire light guide unit 111 and protective unit 12. As a result, the entire light guide unit 111 and protective unit 12 in Figure 1 emit light. By emitting light in this way, the light emitted from the sensor 100 can be seen from any position in the room where the sensor 100 is installed.

[0037] (Effects of the embodiment) As described above, this embodiment includes a prevention part 13 provided in the opening 122. Since the prevention part 13 is a projection, even if the size of the opening 122 is relatively large, the projection will come into contact with a finger attempting to enter through the opening 122. This improves the inflow characteristics of the hot airflow to be detected by the thermistor 14 while preventing contact with the thermistor 14 by the user's finger. Furthermore, it is possible to prevent electrostatic discharge damage caused by the user's finger coming into close proximity to the thermistor 14.

[0038] Furthermore, because the protective portion 13 protrudes from the outer cover 11 side, for example, the strength around the protective portion 13 can be improved, making it possible to prevent damage to the area around the protective portion 13 when an object comes into contact with it.

[0039] Furthermore, since the prevention portion 13 is provided at a position closer to the center of the edge of the opening 122, it can reliably prevent, for example, the object to be contacted from entering the thermistor 14 side, thereby reliably preventing contact between the object to be contacted and the thermistor 14. In addition, it becomes possible to prevent electrostatic discharge damage caused, for example, by a user's finger coming into close proximity to the thermistor 14.

[0040] Furthermore, because the outer surface 131 of the prevention part 13 is curved, it is possible to prevent, for example, the contact object from causing pain to the user's finger when it comes into contact with the prevention part 13. Also, for example, the detection object can be guided to flow along the outer surface of the prevention part 13, thus improving the flow characteristics of the detection object. In addition, for example, a unified appearance can be given to the entire sensor 100, thus improving the design of the sensor 100.

[0041] Furthermore, since at least one prevention unit 13 is provided for each of the multiple openings 122, it is possible to reliably prevent, for example, the entry of the object to be contacted into the thermistor 14, thereby reliably preventing contact between the object and the thermistor 14. In addition, it becomes possible to prevent electrostatic discharge damage caused, for example, by a user's finger coming into close proximity to the thermistor 14.

[0042] [Modifications of the embodiment] While embodiments of the present invention have been described above, the specific configurations and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of ​​each invention described in the claims. Such modifications will be described below.

[0043] (Regarding the problems to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment and details of the invention's configuration. In some cases, only a portion of the problems described above may be solved, or only a portion of the effects described above may be achieved.

[0044] (Regarding decentralization and integration) Furthermore, the above-described configuration is a functional concept and does not necessarily require that the physical structure be as shown in the diagram. In other words, the specific forms of distribution and integration of each part are not limited to those shown in the diagram, and all or part of them can be functionally or physically distributed or integrated in any unit.

[0045] (Regarding the prevention mechanism) Furthermore, the configuration of the prevention part 13 in Figure 2 may be changed as desired. For example, two or more prevention parts 13 may be provided for each opening 122, or prevention parts 13 may be provided for only some of the six openings 122. Also, for example, the position where the prevention part is provided in the opening 122 may be changed as desired. For example, the prevention part 13 may be provided for the circular member 121A or the support member 121B in Figure 5.

[0046] (Regarding the features) Furthermore, the configurations and modified features of the above embodiments may be combined in any way.

[0053] (Effect of the note) According to the disaster prevention equipment described in Appendix 1, a preventative measure is provided at the opening, and since this preventative measure is a projection, even if the size of the opening is relatively large, the projection will come into contact with a finger attempting to enter through the opening. This makes it possible to improve the inflow characteristics of the object being detected to the detection element while preventing contact between the object and the detection element. Furthermore, it becomes possible to prevent electrostatic discharge damage caused by the object coming into close proximity to internal components such as the detection element.

[0054] According to the disaster prevention equipment described in Appendix 2, the protective mechanism protrudes from the outer cover side, which improves the strength around the protective mechanism, for example. This prevents damage to the area around the protective mechanism when an object comes into contact with it.

[0055] According to the disaster prevention equipment described in Appendix 3, the prevention means is provided at a central position on the edge of the opening, which reliably prevents, for example, the object to be contacted from entering the detection element side, thus reliably preventing contact between the object and the detection element. Furthermore, it becomes possible to prevent electrostatic discharge damage caused by the object to come into close proximity to internal components such as the detection element.

[0056] According to the disaster prevention equipment described in Appendix 4, the curved outer surface of the prevention means makes it possible to prevent, for example, the contact object from causing pain when it comes into contact with the prevention means. Also, for example, the detection object can be guided along the outer surface of the prevention means, thus improving the inflow characteristics of the detection object. Furthermore, for example, a unified impression can be given to the entire disaster prevention equipment, thus improving the design of the disaster prevention equipment.

[0057] According to the disaster prevention equipment described in Appendix 5, since at least one prevention means is provided for each of the multiple openings, it is possible to reliably prevent, for example, the object to be contacted from entering the detection target side, thereby reliably preventing contact between the object to be contacted and the detection element. Furthermore, it becomes possible to prevent electrostatic discharge damage caused by the object to be contacted coming into close proximity to internal components such as the detection element.
