It is a compound alarm that can notify. That is, the alarm device 100 has a function of performing a gas leak (fuel gas) notification, an incomplete combustion notification, and a fire notification. In the first embodiment, in addition to the detection and notification function of these gases (methane and carbon monoxide) and smoke, the alarm 100 also performs a notification on heat stroke prevention and a notification on air drying. It is configured.

  The alarm device 100 is installed on a wall surface WS or a ceiling surface C such as a kitchen, a bedroom, a living room, a staircase, or a corridor in consideration of the moving direction (upward) of the detection target gas and the smoke. FIG. 1 shows an example of installation on the wall surface WS near the ceiling surface C of the kitchen as shown in FIG. More specifically, the alarm device 100 is installed on a wall surface WS within 30 cm below the ceiling surface C of the kitchen (room R1) and within several meters from the combustion appliance (gas stove or the like) CA.

  As shown in FIG. 2, the alarm device 100 includes an alarm device main body 1 installed in a room R1, a gas detection unit 2 for detecting gas in the room R1, a temperature detection unit 3 for detecting a temperature in the room R1, The room is provided with a humidity detecting unit 4 for detecting humidity in the room R1, and a smoke detecting unit 5 for detecting smoke in the room R1.

Further, the alarm device 100 includes a control unit 6 including a CPU for controlling the overall operation of the alarm device 100, a storage unit 7, and an output unit 8 for outputting a notification to a user. The output unit 8 includes a speaker 8a, a lamp 8b, and a signal output unit 8c. The control unit 6 and the output unit 8 are an example of the “notifying unit” of the present invention.

  The alarm device body 1 houses (built-in) a gas detection unit 2, a temperature detection unit 3, a humidity detection unit 4, a smoke detection unit 5, a control unit 6, a storage unit 7, and an output unit 8, and detects a gas to be detected. An opening (not shown) is provided to allow the gas to flow into the gas detector 2 and the smoke to the smoke detector 5, respectively.

  The gas detector 2 includes a methane gas sensor (not shown) and a CO gas sensor (not shown), and is configured to detect methane gas and CO gas, respectively. As the methane gas sensor, for example, a semiconductor type sensor that changes electric conductivity (resistance) according to gas adsorption on a semiconductor surface is used. As the CO gas sensor, for example, a constant potential electrolytic sensor that electrolyzes CO gas at a predetermined potential and generates an electrolytic current according to the gas concentration is used. These sensors may be any sensors as long as they can detect the gas to be detected, and the number of sensors is not limited to two. For example, both a methane gas and a CO gas may be detected by a single semiconductor sensor having a selectivity of a detection gas.

  Temperature detection unit 3 includes, for example, a temperature sensor including a thermistor that changes a resistance value according to a temperature change. In this case, the ambient temperature of the alarm device body 1 is obtained based on the change in the resistance value of the thermistor. The temperature sensor is not limited to the above, and may be any sensor as long as it can measure the ambient temperature. The detection result (temperature measurement value) of the temperature detection unit 3 is used not only for temperature compensation of the measurement result of the gas detection unit 2 but also for notification regarding heat stroke prevention and notification regarding air drying. Can be That is, in the first embodiment, a common temperature detecting unit 3 is provided for temperature compensation of the gas detecting unit 2 and for notification of heat stroke prevention and air drying.

  The humidity detecting section 4 includes a humidity sensor and is configured to detect the humidity around the alarm device main body 1. As the humidity sensor, for example, a polymer resistance sensor or a polymer capacitance sensor that changes a resistance value or a capacitance according to the amount of moisture adsorbed on a hygroscopic polymer is used. In such a humidity sensor, humidity (relative humidity) is detected based on a change in resistance or capacitance. The humidity sensor is not limited to the above, and may be any sensor as long as it can measure ambient humidity.

  The smoke detector 5 includes, for example, a light-emitting element and a light-receiving element, and is configured to output a light-reception-amount signal, which is dimmed by smoke on the optical path, to the controller 6. Specifically, the smoke detection unit 5 determines, based on the amount of received light in a state where smoke does not exist (light is not dimmed) as a reference, based on what percentage of the amount of received light is reduced by the smoke on the optical path (dimming rate). To determine the smoke density. The smoke detector 5 may be of a type that receives scattered light scattered by smoke, for example.

  The control unit 6 includes a CPU, controls the detection operation of each detection unit by executing an operation program stored in the storage unit 7, acquires a detection result, and determines whether to perform a predetermined notification. Is configured to function as a control unit of the alarm device 100 that determines whether the alarm has occurred. In addition, the control unit 6 is configured to control the output unit 8 to give a predetermined notification to the user. At the time of notification, the control unit 6 is configured to be able to output various voice messages in addition to a predetermined buzzer sound from the speaker 8a. In addition, the lamp 8b is configured by an LED lamp of a plurality of colors, and the control unit 6 turns on the lamps of different colors according to the content of the notification, and selectively uses continuous lighting or blinking at predetermined time intervals. Is configured. The signal output unit 8c is used to externally output a notification as an external output signal when the alarm 100 is connected to an external device (another alarm).

  The alarm 100 has one switch 9. The switch 9 is, for example, a push-button switch, and receives an input operation and outputs an input signal to the control unit 6. The control unit 6 temporarily stops the sound and the signal by receiving the input operation of the switch 9 during the notification by the sound of the speaker 8a and the signal output from the signal output unit 8c. The notification by the lamp 8b is continued. A plurality of switches 9 may be provided. The switch 9 is an example of the “operation unit” of the present invention.

  The control unit 6 is configured to perform notification regarding gas based on the detection result of the gas detection unit 2 and to perform notification regarding fire based on the detection result of the smoke detection unit 5. In addition, the control unit 6 notifies the user of heat stroke prevention based on at least the detection results of the temperature detection unit 3 and the humidity detection unit 4 among the gas detection unit 2, the temperature detection unit 3, and the humidity detection unit 4. It is configured. Further, the control unit 6 is configured to also perform notification regarding air drying based on the detection result by the humidity detection unit 4.

  The storage unit 7 obtains a threshold value used for the notification determination of the notification about the gas (gas leakage and generation of incomplete combustion gas), the notification about the fire, the notification about the prevention of heat stroke, and the notification about the air drying, and the acquisition of the detection result. , Various information such as notification conditions (conditions for starting notification) and an operation program are stored.

  The control unit 6 is configured to acquire the detected concentrations of methane gas and CO gas from the methane gas sensor and the CO gas sensor of the gas detection unit 2 as detection results. The control unit 6 compares the obtained detected concentration with a threshold value stored in the storage unit 7 in advance to determine whether each concentration of the methane gas and the CO gas has reached a predetermined notification level (abnormality determination standard). It is configured to determine the gas concentration by determining whether or not the determination is made.

  In addition, the control unit 6 is configured to acquire the ambient atmosphere temperature and the relative humidity from the temperature detection unit 3 and the humidity detection unit 4 as detection results. And the control part 6 is comprised so that a heat stroke index may be acquired based on the detection result of temperature and humidity.

  Here, regarding the prevention of heat stroke, for example, the Japanese Society of Biometeorology has proposed that WBGT (Wet-bulb globe temperature, wet-bulb temperature) is used as a guideline for the risk of developing heat stroke. Therefore, in the first embodiment, the control unit 6 is configured to acquire the WBGT as the heat stroke index based on the detection results of the temperature and the humidity.

WBGT is an index that takes in temperature, humidity, and radiant heat, and is defined by the following equation (1) in an indoor room (indoor R1) where there is no solar radiation.
WBGT (° C.) = 0.7 × wet bulb temperature (° C.) + 0.3 × black ball temperature (° C.) (1)
Here, a dedicated measuring device is required for the wet-bulb temperature and the black-bulb temperature, but the WBGT can be easily estimated by using the temperature-humidity table 11 shown in FIG. In FIG. 3, a wider range (air temperature less than 21 ° C., relative humidity less than 20%) is omitted.

  The temperature-humidity table 11 in FIG. 3 is classified into four temperature reference ranges. The uppermost area 11a (WBGT = 31 ° C. or higher) is at the “dangerous” level, and is considered to be at risk of developing heat stroke even during daily living activities, and the elderly need to be careful even at rest. You. The second area 11b from the top (WBGT = 28 ° C or higher and lower than 31 ° C) is at the “severe vigilance” level and requires attention even during daily mild living activities, and also requires attention to rising room temperature. It is said. The third area 11c from the top (WBGT = 25 ° C. or more and less than 28 ° C.) is at the “warning” level, and caution is required when performing moderate or more moderate activities such as cleaning and floor polishing. The lowermost area 11d (WBGT = less than 25 ° C.) is set to the “caution” level, and although it is generally less dangerous, it is recommended that caution be exercised when performing intense exercise.

  The control unit 6 obtains WBGT as a heat stroke index by comparing the detection results of the temperature and the humidity with the temperature-humidity table 11 stored in the storage unit 7.

  Further, in the first embodiment, the control unit 6 is configured to acquire the absolute humidity (volume absolute humidity) for informing about the air drying based on the detection results by the temperature detection unit 3 and the humidity detection unit 4. Have been.

The absolute humidity is obtained from the following equation (2) from the equation of state of the gas.
Absolute humidity (g / m ³ ) = m _w / R × (e / T) ≒ 217 × (e / T) (2)
Here, m _w is the molecular weight of water (≒ 18), R is the gas constant (≒ 8.314), e is the water vapor pressure (hPa), and T is the temperature in absolute temperature (temperature (° C.) + 273). .15). Since the water vapor pressure e is determined by the temperature and the relative humidity, it can be obtained by solving an approximate expression or using a conversion table. Based on the above, the control unit 6 acquires the absolute humidity from the detection results of the temperature and the (relative) humidity. The control unit 6 is configured to perform heat stroke / humidity determination by the method described above.

  Further, as shown in FIG. 2, the control unit 6 obtains, as a smoke density detection result, an extinction rate reduced by smoke on the optical path based on a light reception amount signal of the light receiving element obtained from the smoke detection unit 5. It is configured to The control unit 6 compares the obtained smoke density with a threshold value stored in advance in the storage unit 7 to determine whether or not the smoke density has reached the notification level. Is configured to do so.

  The control unit 6 notifies the user of the notification based on the determination results of the gas concentration determination, the heat stroke / humidity determination, and the smoke concentration determination, and the notification conditions stored in the storage unit 7. Is determined. Further, the control unit 6 is configured to determine whether or not to perform the notification operation based on each determination result and a predetermined notification start condition. As the notification start condition, for example, the control unit 6 obtains each determination result at a predetermined detection timing at one-minute intervals, and the determination results obtained at one-minute intervals are repeated ten times (for ten minutes continuously). T) When the notification condition is satisfied, it is determined that the notification operation is performed. In the following, notification content according to each determination result and notification condition will be described.

<Notice on prevention of heat stroke>
For the notification regarding the heat stroke prevention, the control unit 6 is configured to determine the content of the notification operation according to the WBGT acquired by the heat stroke / humidity determination.

  Specifically, as shown in FIG. 4, when WBGT is equal to or higher than 31 ° C. (region 11a), control unit 6 determines to blink lamp 8b and perform audio notification. In the blinking operation of the lamp 8b, for example, the orange lamp 8b is turned on once at an interval of 5 seconds. In addition, the audio notification outputs a message such as "The room is hot. Let's make it well ventilated and take out moisture and salt" from the speaker 8a. First, the voice notification is performed five times at one-minute intervals as the first notification. Thereafter, while the state in which the WBGT is at least 31 ° C. is ongoing, the notification is performed once every 10 minutes.

  Also, when the WBGT is equal to or higher than 28 ° C. and lower than 31 ° C. (region 11b), the control unit 6 also determines to blink the lamp 8b and perform sound notification. In this case, for the blinking operation of the lamp 8b, for example, the orange lamp 8b is turned on once at an interval of 10 seconds. In addition, the voice notification outputs a message such as "The room is hot. Let's take out moisture and salt" from the speaker 8a. The voice notification is performed once every 30 minutes while the state where the WBGT is 28 ° C. or higher and lower than 31 ° C. is ongoing.

  When the WBGT is equal to or higher than 25 ° C. and lower than 28 ° C. (region 11c), the control unit 6 determines that only the lamp 8b is turned on. In this case, no audio notification is performed. The lamp 8b continuously lights, for example, the orange lamp 8b.

  When the WBGT is lower than 25 ° C. (region 11d), the control unit 6 determines not to perform the notification. At this time, if the lamp 8b is on, the lamp 8b is turned off.

  As described above, the control unit 6 changes the content of the notification operation (the lamp lighting / flashing, the flashing interval, the voice notification content, the voice notification interval, and the like) according to the WBGT notification condition (the WBGT range of four stages). Is configured.

  Here, in the first embodiment, the control unit 6 is configured to acquire the detection result of the gas detection unit 2 when determining the notification content of the notification regarding the heat stroke prevention. Then, when performing a notification regarding heat stroke prevention based on the detection results of the temperature detection unit 3 and the humidity detection unit 4, the control unit 6 reports when the detection result of the gas detection unit 2 satisfies a predetermined condition. It is configured to change the content of the operation. Therefore, in the first embodiment, the control unit 6 notifies the output unit 8 of the notification regarding heat stroke prevention based on the detection results of the gas detection unit 2 as well as the detection results of the temperature detection unit 3 and the humidity detection unit 4. It is configured to perform.

  The case where the detection result of the gas detection unit 2 satisfies the predetermined condition is a case where the detection value (gas concentration) of the gas detection unit 2 shows a predetermined fluctuation pattern set in advance or separately from the gas leak notification level. This is a case where the value exceeds (or falls below) a predetermined threshold value. Such a predetermined fluctuation pattern and a predetermined threshold are set based on, for example, data of detection values (methane gas concentration, CO gas concentration) when the combustion appliance CA is used.

  As shown in the conceptual diagram (time-gas concentration graph) shown in FIG. 5, when a gas leak (or incomplete combustion) occurs, the detected values (methane gas concentration, CO gas concentration) increase with time and become monotonous. It shows a fluctuation trend close to the increase. On the other hand, when there is no gas leakage or incomplete combustion, and no use of the combustion appliance CA, the detected value stably indicates around zero. On the other hand, when the burning appliance CA is used during cooking or the like, the detected value is lower than that at the time of occurrence of gas leakage or incomplete combustion and fluctuates irregularly. For this reason, whether the combustion appliance CA is used is determined by using a variation pattern of the detection value obtained when the combustion appliance CA obtained in advance is used, or by using an upper threshold value and a lower threshold value that match the variation width. Can be estimated. When the combustion appliance CA is used, since other gases are generated and the temperature and humidity are increased, the detection results of the other gas concentrations, the temperature, and the humidity may be determined in combination.

  In the first embodiment, when the detection result of the gas detection unit 2 satisfies a predetermined condition (when it is estimated that the combustion appliance CA is being used), as illustrated in FIG. The apparatus is configured to perform at least one of a notification for prompting the stop of the burning appliance CA being used, an increase in the frequency of notification regarding heat stroke prevention, and an increase in the frequency of determination of notification regarding heat stroke prevention.

  The notification urging the stop of the burning appliance CA in use is, for example, a voice notification message such as “The temperature of the room is rising, so stop the gas appliance in use”. In this case, the control unit 6 notifies the message in addition to the voice notification of the heat stroke notification shown in FIG. 4 (when the WBGT is 31 ° C. or higher and 28 ° C. or higher and lower than 31 ° C.).

  The increase in the notification frequency related to the prevention of heat stroke is a reduction in the lamp blinking interval, a reduction in the voice notification interval, or an increase in the number of times. For example, the control unit 6 changes the notification interval of the audio notification (one notification / 10 minutes) to WBGT 31 ° C. or higher to several minutes, or sets the notification frequency to multiple notifications every 10 minutes. Make changes.

  An increase in the frequency of notification of heat stroke prevention is a change in the notification start condition. For example, in a normal case, when the notification operation is performed when the determination result obtained at one-minute intervals satisfies the notification condition (any of four levels of WBGT ranges) ten times in a row, the control unit 6 The notification start condition is changed so that immediate notification is performed when the determination result meets the notification condition even once. That is, the control unit 6 increases the frequency of determining whether or not to perform the notification from the normal frequency of once every 10 minutes (detected 10 times) to the frequency of every 1 minute (detected once).

<Notice on air drying>
Next, regarding the notification regarding the air drying, the control unit 6 is configured to determine the content of the notification operation when performing the notification in accordance with the notification condition of the absolute humidity acquired by the heat stroke / humidity determination. .

Here, in connection with air drying, research results have shown that the level of absolute humidity affects the survival rate of influenza virus. Specifically, when the absolute humidity is 7 g / m ³ or less, the 6-hour survival rate of the seasonal influenza virus is about 20%. When the absolute humidity is 11 g / m ³ or less, the 6-hour survival rate is about 5% and the absolute humidity is 17 g / m 3. It is said that if it is ³ or less, the 6-hour survival rate becomes approximately 0%. It is thought that the lower the 6-hour survival rate, the lower the possibility of infection with influenza virus. That is, influenza infection can be prevented by maintaining sufficient humidity so that the air does not dry out.

Therefore, as shown in FIG. 6, when the absolute humidity is equal to or less than 7 g / m ³ , the control unit 6 blinks the lamp 8b and determines to perform audio notification. In the blinking operation of the lamp 8b, for example, the blue lamp 8b is turned on once at an interval of 5 seconds. The audio notification outputs a message such as "Let's keep the room from drying" from the speaker 8a. The audio notification is performed once every 30 minutes while the absolute humidity is 7 g / m ³ or less.

When the absolute humidity is equal to or less than 11 g / m ³ , the control unit 6 makes only the lamp 8b blink, and determines not to perform the voice notification. In the blinking operation of the lamp 8b, for example, the blue lamp 8b is turned on once at an interval of 10 seconds.

When the absolute humidity is 17 g / m ³ or less, the control unit 6 determines not to perform the notification. If the lamp 8b is on, the lamp 8b is turned off. As described above, in the first embodiment, the notification condition of the notification regarding the air drying is set according to the three-stage absolute humidity range.

  The above are the notification conditions and notification contents regarding heat stroke prevention and air drying. The thresholds and notification conditions for these notifications are stored in the storage unit 7 in advance. In the case of performing sound notification in the notification regarding heat stroke prevention and air drying, the control unit 6 sets the notification sound volume to be lower than the notification sound volume in the case of the notification regarding gas and the notification regarding fire. Control. This reflects the urgency of the content of the notification, and prevents the notification about heat stroke prevention and air drying from giving a user an unnecessarily alarming feeling.

<Other announcements>
As for the notification about gas (gas leakage and incomplete combustion gas generation), as shown in FIG. 2, the control unit 6 sets the gas concentration to a predetermined notification level (abnormality determination reference) stored in the storage unit 7. If it is determined that the time has been reached, it is determined to execute a predetermined notification operation. The notification operation is performed by, for example, notification by voice (a gas leak or occurrence of incomplete combustion) and lamp lighting (red, yellow).

  As for the notification about the fire, the control unit 6 performs a predetermined notification operation when the smoke density (dimming rate) reaches a predetermined notification level (abnormality criterion) stored in the storage unit 7. decide. In the first embodiment, the control unit 6 changes at least one of the abnormality determination criterion and the determination frequency by the smoke detection unit 5 based on the detection result of the humidity detection unit 4 in the first embodiment, or It is configured to discriminate between smoke and water vapor based on both the detection result of the smoke detection unit 5 and the detection result of the humidity detection unit 4.

The control unit 6 obtains the effective humidity based on the current and past humidity detection results stored in the storage unit 7 and determines the abnormality determination criterion and the frequency of the determination by the smoke detection unit 5, and according to the value of the effective humidity. At least one of the abnormality determination criterion (report level) and the determination frequency is changed. The effective humidity is the humidity obtained by integrating the relative humidity in the past several days represented by the following equation (3), and is used as an index indicating the degree of drying of the wood.
The effective humidity (%) = (1-r ) (H 0 + rH 1 + r 2 H 2 + ···) ··· (3)
r is a predetermined coefficient, and r = 0.7 is used in a weather station or the like. H ₀ , H ₁ , H ₂ ,..., H _n are the average humidity of n days before, and H ₀ indicates the humidity of the current day. It is generally said that when the effective humidity is about 50% to 60%, the risk of fire increases.

  When the acquired effective humidity is lower than a predetermined threshold (for example, 60%), the control unit 6 lowers the abnormality determination criterion (notification level) by the smoke detection unit 5. For example, at normal times, if the notification level of the determination result by the smoke detection unit 5 is set to the dimming rate of 10%, and the effective humidity is below the threshold, the control unit 6 sets the notification level to the dimming rate. Reduce to 7.5%.

  Regarding the determination frequency, for example, at normal times, the control unit 6 performs the notification operation when the determination result obtained at one-minute intervals meets the notification condition 10 times consecutively (when the notification level is reached). Execute. On the other hand, when the effective humidity is lower than the threshold, the control unit 6 changes to perform the immediate notification when the determination result meets the notification condition even once. That is, by changing the notification start condition, the control unit 6 changes the frequency of determining whether or not to perform the notification from the normal frequency of once every 10 minutes (10 detections) to 1 minute (1 detection). Increase to every frequency. As a result, earlier fire detection is possible during drying, which has a high risk of fire.

  Next, regarding the discrimination between smoke and water vapor, when water vapor is generated during cooking in a kitchen or the like, the water vapor arriving on the optical path of the smoke detection unit 5 diminishes light, so that the smoke and water vapor are erroneously determined. The possibility of detection arises. The generation of such water vapor usually has a sharp change in the dimming rate in the case of water vapor as compared with the fluctuation of the smoke density (dimming rate) due to smoke at the time of the fire. It is possible to discriminate between smoke and water vapor based on such fluctuations.

  In the first embodiment, in addition to the determination of smoke and water vapor based on the temporal change in the detection result, the control unit 6 determines the detection result (dimming rate) of the smoke detection unit 5 and the detection result of the humidity detection unit 4. , The discrimination between smoke and water vapor is performed. For example, when the determination is made based on the temporal change in the detection result of the smoke density, the control unit 6 considers the detection result of the humidity detection unit 4 and continuously adjusts the humidity to a threshold value for a predetermined time. If it is (for example, 70%) or more, it is determined to be water vapor. As a result, it is possible to more accurately discriminate between smoke and water vapor, and it is possible to suppress occurrence of erroneous detection.

(Notification judgment and notification operation of alarm)
Next, with reference to FIG. 7, a description will be given of a control operation relating to the notification determination and the notification operation of the alarm device 100 according to the first embodiment. The operation control of the alarm device 100 is executed by the control unit 6.

  In step S1, the control unit 6 determines whether or not it is a gas detection timing, and if not, proceeds to step S4. If it is the gas detection timing, in step S2, the control unit 6 executes the gas detection process by the gas detection unit 2, acquires the methane gas concentration and the CO gas concentration as the detection results, and stores the detected gas concentration in the storage unit 7. Store the result. In step S3, the control unit 6 determines whether or not the detection result satisfies the notification start condition, and determines whether or not to perform the notification operation (gas alarm determination process). That is, the control unit 6 determines to execute the notification operation when the state in which the detection result reaches the notification level of the notification about the gas has been continuously continued ten times. The control unit 6 sets the notification flag of the notification about the gas to ON (notification execution) or OFF (not to execute notification) and stores it in the storage unit 7.

  In step S4, the control unit 6 determines whether or not it is the smoke detection timing. If it is not the smoke detection timing, the process proceeds to step S7. If it is the smoke detection timing, in step S5, the control unit 6 executes the smoke detection process by the smoke detection unit 5, acquires the smoke density (dimming rate) as the detection result, and stores the smoke density (dimming rate) in the storage unit 7. The detection result is stored. In step S6, the control unit 6 determines whether the detection result satisfies the notification start condition, and determines whether to perform the notification operation (smoke alarm determination processing). That is, when the state in which the detection result reaches the notification level of the notification regarding the fire has continued for ten times, the control unit 6 determines to execute the notification operation. The control unit 6 turns on (notification execution) or off (does not execute notification) the notification flag of the notification regarding the fire, and stores it in the storage unit 7.

  In step S7, the control unit 6 determines whether or not it is time to detect the temperature and humidity (temperature and humidity). If not, the process proceeds to step S11. If it is the temperature / humidity detection timing, in step S8, the control unit 6 executes the temperature detection process by the temperature detection unit 3, acquires the temperature as the detection result, and stores the detection result in the storage unit 7. . In step S9, the control unit 6 executes the humidity detection process by the humidity detection unit 4, acquires the relative humidity as the detection result, and causes the storage unit 7 to store the detection result.

  In step S10, the control unit 6 determines whether or not to perform notification of a notification regarding heat stroke and air drying. That is, the control unit 6 acquires the WBGT based on the detected temperature and humidity and the temperature-humidity table 11, and acquires the absolute humidity based on the detected temperature and humidity. Subsequently, the control unit 6 determines whether the WBGT and the absolute humidity satisfy the notification start condition, and determines whether to perform the notification operation. That is, when the state in which the detection result (WBGT) satisfies any of the notification conditions shown in FIG. 4 has been continued ten times, the control unit 6 determines to execute the notification operation. Similarly, when the detection result (absolute humidity) corresponding to any one of the notification conditions shown in FIG. 6 has been continuously continued 10 times, the control unit 6 determines to execute the notification operation. The control unit 6 stores in the storage unit 7 the notification flag of the notification regarding the heat stroke prevention and the notification flag of the notification regarding the air drying, which are turned on (notification executed) or turned off (not executed).

  In step S11, the control unit 6 performs a notification content determination process when performing notification based on the notification flags set in steps S3, S6, and S10. For example, in the case of notification regarding heat stroke prevention, the control unit 6 determines whether the latest WBGT corresponds to any of the notification conditions illustrated in FIG. 4 (whether the WBGT applies to any of the areas 11a to 11d). , The content of the notification operation (lamp lighting / flashing, flashing interval, voice notification content, voice notification interval, etc.) is determined. For the notification regarding the air drying, the control unit 6 determines the execution of the notification operation and the content of the notification, for example, according to which of the notification operation conditions shown in FIG. Regarding the notification about gas and the notification about fire, the notification operation and the notification content are determined according to the respective notification conditions.

  In step S12, the control unit 6 performs a sound sounding process, and executes a notification sound (message) and a buzzer sound according to the determined notification contents. When the notification content does not include the voice notification (for example, when the WBGT is lower than 28 ° C.), the voice notification is not performed.

  In step S13, the control unit 6 performs a lamp display process, and performs lighting / flashing of the lamp 8b according to the determined notification content. When the lamp content is not included in the notification content (for example, when the WBGT is lower than 25 ° C.), the notification by the lamp display is not performed.

  In step S14, the control unit 6 performs an external output process, and outputs an external output signal from the signal output unit 8c according to the determined notification content when an external device (other alarm device or the like) exists. After the above processing, the process returns to step S1, and the operations of the alarm device 100 are controlled by repeating these steps S1 to S14.

(Condition change processing for notification regarding heat stroke prevention)
Next, with reference to FIG. 8, a description will be given of a condition changing process of notification regarding heat stroke prevention based on the detection result of the gas detection unit 2.

  In step S21 in FIG. 8, the control unit 6 reads the detection result (gas concentration) of the gas detection unit 2 from the storage unit 7 for a predetermined period.

  In step S22, the control unit 6 determines whether the detection result of the gas detection unit 2 satisfies a predetermined condition. The method of determination is as described above. If it is determined that the predetermined condition is satisfied (it is estimated that the combustion appliance CA is being used), the control unit 6 changes the notification start condition / notification content of the notification regarding heat stroke prevention in step S23. The contents of the change are, for example, those shown in FIG.

  As a result, the notification start condition of the notification determination in step S10 in FIG. 7 and the notification content in the notification content determination process in step S11 are changed.

  On the other hand, when it is determined that the predetermined condition is not satisfied (it is estimated that the combustion appliance CA is not used), the control unit 6 ends the process without changing the notification start condition / notification content. Although not shown, after the notification start condition / notification content is changed in step S23, it is determined in step S22 that the predetermined condition is not satisfied (that is, the use of the combustion appliance CA is stopped. ), The changed notification start condition / information content is returned to the original.

(Process for changing conditions for fire notification)
Next, with reference to FIG. 9, a description will be given of a condition changing process of notification about fire based on the detection result of the humidity detection unit 4.

  In step S31 of FIG. 9, the control unit 6 reads out the detection result (relative humidity) of the humidity detection unit 4 for a predetermined period (current and past several days) from the storage unit 7. In step S32, the control unit 6 acquires (calculates) the effective humidity based on the read humidity data for the present and the past several days.

  In step S33, the control unit 6 determines whether the effective humidity has fallen below a predetermined threshold value (for example, 60%). When determining that the effective humidity is lower than the predetermined threshold, the control unit 6 changes the notification condition / notification start condition (the abnormality determination criterion, the determination frequency) of the notification regarding the fire in Step S34. The details of the change are as described above. As a result, the notification condition / notification start condition in the smoke alarm determination process in step S6 in FIG. 7 is changed.

  On the other hand, when determining that the effective humidity is equal to or more than the predetermined threshold, the control unit 6 ends the process without changing the notification condition / notification start condition. This process may be performed, for example, every day, and the changed notification condition may be reset every day.

(Steam determination processing)
Next, referring to FIG. 10, a description will be given of a water vapor determination process of the detection result of the smoke detection unit 5 based on the detection result of the humidity detection unit 4.

  In step S41 of FIG. 10, the control unit 6 reads out the detection result (smoke density) of the smoke detection unit 5 from the storage unit 7 for a predetermined time. In step S42, the control unit 6 determines whether the current (latest) detection result is due to smoke or water vapor based on the temporal fluctuation of the read smoke concentration data for the predetermined time. If it is determined that the processing is not due to the water vapor, the control unit 6 ends the processing as it is.

  When determining that the detection result is due to the water vapor, the control unit 6 reads the detection result (relative humidity) of the humidity detection unit 4 from the storage unit 7 for a predetermined time in step S43. Then, in step S44, the control unit 6 determines whether the read humidity is equal to or higher than a predetermined threshold (for example, 70%) for a predetermined time continuously.

  If the difference is equal to or larger than the predetermined threshold, the process proceeds to step S45, and the control unit 6 determines that the current (latest) detection result of the smoke detection unit 5 is due to water vapor. In this case, the control unit 6 changes conditions such as raising the condition of the determination time (number of determinations) as the notification start condition. As a result, if the detection result is actually based on water vapor, the smoke density is quickly reduced, and notification (erroneous notification) caused by the water vapor is prevented.

  On the other hand, if it is determined in step S44 that the humidity is less than the predetermined threshold, the control unit 6 terminates the process without performing the water vapor determination (determining that the current detection result is due to smoke).

  Note that the condition change processing in FIGS. 8 and 9 and the water vapor determination processing in FIG. 10 may be performed in parallel with the control of the notification determination and notification operation in FIG. May be incorporated as a part.

(Effect of First Embodiment)
In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, the temperature detector 3 provided in the alarm device main body 1 and detecting the temperature of the room R1 and the humidity detector provided in the alarm device main body 1 and detecting the humidity of the room R1 And an alarm device main body 1 for notifying a gas on the basis of the detection result of the gas detection unit 2, and at least the temperature detection unit 3 of the gas detection unit 2, the temperature detection unit 3, and the humidity detection unit 4. By providing the control unit 6 and the output unit 8 for performing notification regarding heat stroke prevention based on the detection result of the humidity detection unit 4, notification of gas such as gas leakage is performed based on the detection result of the gas detection unit 2. In addition to what can be done, it is possible to obtain information (WBGT) that is a guide for the risk of developing heat stroke from the detection results (temperature and humidity) of the temperature detection unit 3 and the humidity detection unit 4. It is possible to perform notification about heat stroke prevention based on the obtained information. As a result, in addition to the notification about gas such as gas leakage, it is also possible to appropriately notify the user of a situation that requires attention in the daily living environment such as heat stroke. In addition, the alarm device 100 that performs notification of a gas leak or the like generally has a high notification capability and can surely recognize a gas leak or the like by a user. By adding the function of notification about prevention, unlike a thermo-hygrometer that promotes prevention of heat stroke, which has not so high notification capability, it is possible to make the user more surely recognize the notification about heat stroke prevention.

  In the first embodiment, as described above, the notification regarding the heat stroke prevention is performed based on not only the detection results of the temperature detection unit 3 and the humidity detection unit 4 but also the detection results of the gas detection unit 2. The control unit 6 and the output unit 8 are configured. Thus, it is possible to estimate that the combustion appliance CA is used from the detection result of the gas detection unit 2, so that it is possible to determine whether the temperature and humidity of the room R1 are more likely to increase. As a result, the situation of the room R1 can be more specifically grasped based on the detection result of the gas detection unit 2, so that the notification regarding the heat stroke prevention can be performed more appropriately.

  Further, in the first embodiment, as described above, when the notification regarding the heat stroke prevention is performed based on the detection results of the temperature detection unit 3 and the humidity detection unit 4, the detection result of the gas detection unit 2 is set to a predetermined condition. When the condition is satisfied, at least one of the notification prompting the stop of the burning appliance CA in use, the increase in the notification frequency regarding the prevention of heat stroke, or the increase in the determination frequency of the notification regarding the prevention of heat stroke is performed. With this configuration, when the detection result of the gas detection unit 2 satisfies a predetermined condition that the combustion appliance CA is estimated to be used, if the combustion appliance CA is configured to be urged to stop, the indoor R1 can be updated. It is possible to suppress an increase in temperature and humidity. Further, if the notification frequency related to heat stroke prevention is increased (the number of times of notification is increased or the notification interval is shortened), the notification of heat stroke prevention can be transmitted to the user more reliably. In addition, if the system is configured to increase the frequency of notification of heat stroke prevention, the system can promptly respond to cases such as when the temperature and humidity of the room further rises and the risk of heat stroke increases. Can be done early.

  In the first embodiment, as described above, in addition to the notification about the gas and the notification about the prevention of heat stroke, the notification about the air drying is also performed based on the detection results by the temperature detection unit 3 and the humidity detection unit 4. The control unit 6 and the output unit 8 are configured. Thereby, in addition to the notification regarding the gas leakage and the prevention of heat stroke, the user can be encouraged to perform the humidity management for preventing the air drying, so that a more versatile alarm 100 can be provided. As a result, it is possible to reduce the risk of influenza infection by maintaining an appropriate humidity.

  In the first embodiment, the smoke detector 5 is further provided as described above. Thus, not only gas leak notification, but also fire notification by detecting smoke at the time of fire occurrence can be performed. In the first embodiment, at least one of the abnormality determination criterion and the determination frequency by the smoke detection unit 5 is changed based on the detection result of the humidity detection unit 4, or the detection result of the smoke detection unit 5 and the humidity are changed. Based on both of the detection results of the detection unit 4, a determination is made between smoke and water vapor. If the smoke detection unit 5 is configured to change at least one of the abnormality determination criterion and the determination frequency based on the detection result of the humidity detection unit 4, the abnormality determination criterion is reduced particularly when the dry state continues (high sensitivity). ) Or the frequency of determination can be increased, so that fire detection (notification) can be performed quickly and appropriately. Further, if it is configured to discriminate between smoke and water vapor based on both the detection result of the smoke detection unit 5 and the detection result of the humidity detection unit 4, it is possible to detect an increase in humidity when steam (steam) is generated. Therefore, erroneous detection of smoke detection can be suppressed, and fire detection (notification) can be performed more appropriately. As a result, it is possible to provide a multifunctional and high-performance alarm 100 having not only a notification of gas leakage and heat stroke prevention but also an appropriate (enhanced) fire notification function.

[Second embodiment]
Next, a second embodiment will be described with reference to FIGS. In the second embodiment, unlike the first embodiment in which the present invention is applied to a gas alarm installed in a kitchen, an example in which the present invention is applied to a fire alarm installed in a living room or a bedroom will be described. . The same components as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and are not described.

(Alarm configuration)
As shown in FIG. 11, an alarm 200 according to the second embodiment is a fire alarm installed in a room R2, and is fixedly installed on a wall WS or a ceiling C of a living room, a bedroom, or the like. FIG. 11 shows an example in which the alarm 200 is attached to the ceiling surface C.

  The alarm 200 according to the second embodiment is different from the alarm 100 according to the first embodiment in that the alarm 200 is mainly provided for alarming. Note that, as the alarm 200 (fire alarm) for use in a living room or a bedroom, the gas leak (fuel gas) notification function is not necessarily required when the combustion appliance CA is not provided in the room R2 where the alarm is provided. On the other hand, for example, when a heating device such as a gas heater is installed in the room R2, the gas leak notification function is useful. The incomplete combustion alarm function is useful for early detection of a fire, because carbon monoxide is often generated before the generation of smoke in the event of a fire. Is also very useful.

  The device configuration of the alarm 200 is the same as that of the first embodiment (see FIG. 2). The alarm 200 is configured to perform gas leak (fuel gas) notification, incomplete combustion notification, and fire notification. In the second embodiment, in addition to the function of detecting and detecting these gases (methane and carbon monoxide) and smoke, the alarm 200 also performs a notification on heat stroke prevention and a notification on air drying. It is configured.

  Other configurations of the alarm 200 in the second embodiment are the same as those in the first embodiment.

(Effect of Second Embodiment)
Also in the alarm 200 (fire alarm) for the living room and bedroom as in the above-described second embodiment, the notification about the gas based on the detection results of the temperature detection unit 3, the humidity detection unit 4, and the gas detection unit 2 is provided. The control unit 6 and the output unit that perform notification on heat stroke prevention based on at least the detection results of the temperature detection unit 3 and the humidity detection unit 4 among the gas detection unit 2, the temperature detection unit 3, and the humidity detection unit 4. By providing 8 and above, in addition to notification about gas such as gas leakage, it is also possible to appropriately notify a situation that requires attention in the daily life environment of the user such as heat stroke.

  Other effects of the second embodiment are the same as those of the first embodiment.

[Third embodiment]
Next, a third embodiment will be described with reference to FIGS. In the third embodiment, another specific example of the notification regarding the heat stroke prevention and the notification regarding the air drying will be described. The configuration of the apparatus is the same as that of the first embodiment, and a description thereof will not be repeated.

  In the third embodiment, for the notification regarding the heat stroke prevention and the notification regarding the air drying, different notification conditions and notification operations from those in the first embodiment are set in the alarm 300 (see FIG. 2).

(Information about heat stroke prevention)
First, as shown in FIG. 12, for the notification related to the prevention of heat stroke, notification conditions of three stages (alert, caution, and normal state) are set, and the content of the notification operation differs for each stage. The alert level is higher in the order of the alert state 310, the alert state 320, and the normal state 330, and the alarm device 300 performs an alert with a higher alert effect in descending order of the alert level.

<Alert state>
The alert condition of the alert state 310 is that the WBGT is 31 ° C. or higher (region 11a, see FIG. 3). In this case, the control unit 306 (see FIG. 2) notifies both the lamp 8b and the speaker 8a. The lamp 8b is continuously lit, for example, in orange. The speaker 8a outputs a heat stroke warning message. The heatstroke warning message is, for example, a message saying, "The room is getting hot. Let's make it well ventilated and take water and salt."

  In the alert state 310, automatic sound notification (e.g., automatic notification) over time and sound notification at the time of switch input performed when the switch 9 is input are set.

  In the automatic notification, a heat stroke warning message is continuously output a plurality of times (three times) as one notification operation. In the automatic notification, 30 minutes are set as the notification interval, and two times (two turns) are set as the number of additional notifications (upper limit). That is, if the notification threshold value is continuously exceeded for 30 minutes after the first notification, the second notification operation is performed. If the notification threshold value is continuously exceeded for another 30 minutes thereafter, a third notification operation is performed. After the first notification, after the additional notification is performed twice, the additional notification by the automatic notification is not performed.

  In the sound notification at the time of switch input, a heat stroke warning message is output only once. The voice notification at the time of the switch input is a notification (one time output) having a smaller notification effect than the voice notification by the automatic notification (three continuous outputs). This is because, when the switch 9 is input, the user's attention is directed to the alarm device 300, so that the notification can be sufficiently transmitted to the user.

<Attention state>
The notification condition of the attention state 320 is that the WBGT is equal to or higher than 28 ° C. and lower than 31 ° C. (region 11b, see FIG. 3). In this case, the control unit 306 reports in principle by the lamp 8b without performing voice reporting. The lamp 8b blinks differently from the alert state 310. The blinking operation is, for example, turned on once at intervals of 5 seconds.

  In the attention state 320, automatic notification by voice is not performed. In the caution state 320, as an exception, audio notification at the time of switch input is set. Voice notification at the time of switch input is the same as in the alert state 310.

<Normal state>
In the third embodiment, a state in which the WBGT is lower than 28 ° C. (regions 11c and 11d, see FIG. 3) is set as a normal state 330 in which notification is not performed. In the normal state 330, neither the lamp 8b nor the speaker 8a notifies.

(Announcement on air drying)
As shown in FIG. 13, the notification regarding the air drying has four notification conditions (second warning, first warning, caution, and normal), and the content of the notification operation differs for each stage.

  Unlike the first embodiment, in the third embodiment, in addition to the absolute humidity, a notification threshold of the relative humidity and the temperature is set as the notification condition of the notification regarding the air drying.

  The alert level is higher in the order of the second alert state 340, the first alert state 350, the alert state 360, and the normal state 370.

  In the third embodiment, the control unit 306 performs a second notification operation including a sound in the case of the first alert state 350, and in the case of the second alert state 340 having a higher alert level than the first alert state 350, It is configured to perform a first notification operation that does not include voice. That is, in the third embodiment, in the state where the alert level is relatively low (first alert state 350), the second alerting operation with a higher alerting effect is performed, and the alert level is relatively high (second alert state). In state 340), a first notification operation having a relatively low notification effect is performed. The first alert state 350 is an example of the “first alert level” of the present invention. The second alert state 340 is an example of the “second alert level” of the present invention.

<Second alert state>
The notification condition of the second alert state 340 is set to correspond to when the user goes to bed or is absent. The absolute humidity, the relative humidity, and the temperature increase when the user is active in the room R1 (R2). Therefore, by appropriately setting the notification thresholds of the absolute humidity, the relative humidity, and the temperature, each detection value can be set to exceed the notification threshold of the second alert state 340 when the user is inactive (at bedtime) or when the user is absent. . In the third embodiment, three notification thresholds of an absolute humidity of 7 g / m ³ or less, a relative humidity of 40% or less, and a temperature of less than 10 ° C. are set as the notification conditions of the second alert state 340.

  As a notification operation of the second alert state 340, the control unit 306 executes, in principle, a first notification operation of notifying by the lamp 8b without performing sound notification. The lamp 8b is continuously lit, for example, in blue.

  In the second alert state 340, no audio notification by automatic notification is performed. For this reason, it is possible to suppress the notification sound from being output when the user is asleep or absent.

  In the second alert state 340, as an exception, audio notification at the time of switch input is set. In the sound notification at the time of switch input, a dry warning message is output only once. The speaker 8a outputs a dry warning message. The dry warning message is, for example, a message "Let's keep the room dry."

<First alert state>
The first alert state 350 is set to correspond to an air drying state during the user's activity. That is, in consideration of the activity of the user in the room R1 (R2), the notification threshold of at least one of the absolute humidity, the relative humidity, and the temperature is set lower than the notification threshold in the second alert state 340.

More specifically, three notification thresholds of an absolute humidity of 7 g / m ³ or less, a relative humidity of 40% or less, and a temperature of 10 ° C. or more and less than 30 ° C. are set as notification conditions of the first alert state 350. I have. Therefore, in the third embodiment, the temperature threshold is set lower in the first alert state 350 than in the second alert state 340, and the alert level is set lower.

  In the first alert state 350, a second alert operation having a higher alert effect is executed than in the first alert operation in the second alert state 340. The control unit 306 executes a second notification operation of notifying both the lamp 8b and the speaker 8a as a notification operation of the first alert state 350. The lamp 8b is continuously turned on. The speaker 8a outputs a dry warning message.

  In the first alert state 350, automatic sound notification (e.g., automatic notification) over time and sound notification at the time of switch input are set.

  In the automatic notification, a drying warning message is continuously output a plurality of times (three times) as one notification operation. In the automatic notification, 30 minutes are set as the notification interval, and two times (two turns) are set as the number of additional notifications (upper limit). In the sound notification at the time of switch input, a dry warning message is output only once.

<Attention state>
As notification conditions for the caution state 360, two notification thresholds of an absolute humidity of 7 g / m ³ or less and a relative humidity of higher than 40% are set. No temperature threshold is set. In this case, the control unit 306 reports in principle only with the lamp 8b. The lamp 8b blinks differently from the second alert state 340. The blinking operation is, for example, turned on once at intervals of 5 seconds. In the caution state 360, automatic notification by voice is not performed, and as an exception, voice notification at the time of switch input is set. The sound notification at the time of switch input is the same as the above-mentioned second alert state 340 and first alert state 350.

<Normal state>
In the third embodiment, the state where the absolute humidity is higher than 7 g / m ³ is set as the normal state 370. In the normal state 370, neither the lamp 8b nor the speaker 8a notifies.

(Effect of Third Embodiment)
In the third embodiment, as described above, for the notification regarding the air drying, in the case of the first alert state 350, the second alert operation including the audio alert is performed, and the second alert operation having a higher alert level than the first alert state 350 is performed. The control unit 306 and the output unit 8 are configured to perform the first notification operation not including the sound notification in the case of the alert state 340. Here, the degree of dryness of the room R1 (R2) is low humidity (dry) when inactive, such as when absent or while sleeping. Therefore, by setting a dry state that occurs only when the user is not active, such as when he is absent or sleeping, as the second alert state 340, unnecessary notification when the user is not active can be suppressed, which is convenient for the user. Can be improved.

(Modification of Third Embodiment)
In the third embodiment, an example in which the first notification operation not including the audio notification is performed in the case of the second alert state 340 has been described, but instead of the first notification operation not including the audio notification, the non- notification is not performed. It may be a notification.

[Fourth embodiment]
Next, a fourth embodiment will be described with reference to FIG. In the fourth embodiment, an example will be described in which the operation at the time of accepting an input of a switch is changed according to the detection target that is currently being detected. The configuration of the apparatus is the same as that of the first embodiment, and a description thereof will not be repeated.

  In the alarm device 400 of the fourth embodiment, the control unit 406 (see FIG. 2) is configured to change the operation at the time of receiving the input of the switch according to the detection target currently being detected. Therefore, the switch 9 is configured to receive a command to start the function checking operation of the alarm device 400 in addition to temporarily stopping the sounding of the sound.

(Switch input acceptance)
First, reception of an input operation by the switch 9 will be described. In the fourth embodiment, one switch 9 is configured to be able to receive a plurality of input operations. The reception of a plurality of input operations by one switch 9 depends on the difference in the length of time the switch 9 is pressed. The control unit 406 accepts a first input operation (short-press input) when the switch 9 continues to be pressed for a short time shorter than a predetermined threshold (for example, 3 seconds). In addition, when the pressing duration of the switch 9 is longer than a predetermined threshold (for example, 3 seconds), the control unit 406 accepts a second input operation (long press input).

(Operation when receiving switch input)
The switch 9 receives an instruction to stop sounding. When the control unit 406 receives a short press input of the switch 9 during the notification by the sound of the speaker 8a, the sound of the sound is temporarily stopped. During the notification by voice sound, the long press input is invalidated. Regardless of the type of notification, the control unit 406 stops sound for all types of notification. The types of voice notification are mainly gas leak notification, incomplete combustion notification, fire notification, notification on heat stroke prevention, and notification on air drying.

  In the fourth embodiment, the switch 9 receives a command to start a function check operation. The function check operation is a check operation (check operation) as to whether or not the function of the alarm device is working normally.

  The function check operation includes a function check operation when a short press input is received (short press check) and a function check operation when a long press input is received (long press check). The control unit 406 receives an instruction to stop sounding a voice and an instruction to execute a short press check (function confirmation operation) by a common first input operation (short press input).

  In the short push inspection, the control unit 406 performs a function confirmation (inspection) operation of a device included in the alarm device 400. That is, the control unit 406 performs inspection of the gas detection unit 2, temperature detection unit 3, humidity detection unit 4, and smoke detection unit 5, and inspection of the output unit 8 (speaker 8a, lamp 8b, signal output unit 8c). The short push inspection is performed by checking the output voltage value and the resistance value of each detection unit and the output unit 8, and the like.

  In the long press inspection, the control unit 406 performs a function confirmation (inspection) operation related to various notification operations. That is, the control unit 406 performs a test of a notification operation for various types of notification such as gas leak notification, incomplete combustion notification, fire notification, notification about heat stroke prevention, and notification about air drying. In the long press inspection, the control unit 406 performs notification by the output unit 8 (output of a notification sound of the speaker 8a, lighting / flashing of the lamp 8b, and signal output of the signal output unit 8c) for each type of notification. The long press inspection is a function confirmation operation that allows the user to confirm whether the notification operation has been performed normally.

(Function confirmation operation execution conditions)
Next, an execution condition of the function checking operation will be described. The control unit 406 performs a function checking operation when the switch 9 is input in a predetermined operation state.

  As shown in FIG. 14, the operating states of the alarm device 400 include a normal monitoring state 410, a first notification state 420, a second notification state 430, and notification (not shown) by the sounding of the above-described sound.

  The normal monitoring state 410 is a non-reporting state in which the detection value of each detection unit does not exceed any of the notification thresholds (a state in which none of the notification conditions are satisfied). The first notification state 420 and the second notification state 430 are states in which the detection value of the detection unit exceeds any notification threshold. However, the first notification state 420 and the second notification state 430 do not include the notification by sounding. The first notification state 420 and the second notification state 430 correspond to, for example, a state in which notification is performed only by the lamp 8b or a state in which sound is stopped after sound notification by automatic notification.

  The first notification state 420 and the second notification state 430 are distinguished by the detection target. Specifically, in the first notification state 420, fire, incomplete combustion (CO), and gas leakage are set as detection targets. In the second notification state 430, prevention of heat stroke and air drying are set as detection targets.

  The control unit 406 changes the operation of the switch 9 when receiving an input for each of these operation states. As described above, during the notification by the sounding of the sound, the sounding of the sound is temporarily stopped by the short-press input, so that the function checking operation is not executed. Hereinafter, the normal monitoring state 410, the first notification state 420, and the second notification state 430 will be described.

<Normal monitoring state>
In the normal monitoring state 410 (non-notifying), the control unit 406 performs a short press inspection (a function confirmation operation) in response to receiving a short press input. In this case, the control unit 406 outputs a notification sound indicating the result of the confirmation by the function confirmation operation.

  If the inspection result is normal, the control unit 406 causes the speaker 8a to output a notification sound indicating normality. The notification sound at normal time in the normal monitoring state 410 is, for example, a voice message “normal”. If the inspection result is abnormal, a notification sound indicating that the inspection is abnormal is output. The notification sound at the time of detection of an abnormality is, for example, a voice message saying "It is out of order. Please contact your dealer."

<First notification state>
In the first notification state 420, the control unit 406 does not execute the short press inspection (the function confirmation operation) even if the short press input is received. Therefore, when the detection value of the fire, incomplete combustion (CO), or gas leak exceeds the notification threshold, even if there is an operation input by the user, the short press inspection is not performed, and the notification to the user is prioritized. Is done.

<Second notification state>
In the second notification state 430, the control unit 406 performs a short press inspection (a function confirmation operation) in response to receiving a short press input. As described above, in the fourth embodiment, when the short push input of the switch 9 is received in the first notification state 420, the alarm device 400 does not execute the function confirmation operation, and performs the short notification of the switch 9 in the second notification state 430. When a push input is received, a function check operation is performed. That is, whether or not to execute the function confirmation operation differs depending on the detection target that is currently being detected.

  The detection target assigned to the second notification state 430 is a situation to be careful in a daily living environment such as heat stroke prevention and air drying, and has a relatively low urgency as compared with the detection target in the first notification state 420. . For this reason, in the fourth embodiment, for a detection target having a relatively low urgency, even if the detection value exceeds the notification threshold, the short press inspection (function confirmation operation) is performed with priority given to the user's intention. I do.

  Further, in the fourth embodiment, different notification is performed depending on the operation state also regarding the notification of the confirmation result by the short push inspection. The control unit 406 notifies the confirmation result by a different notification operation according to the detection target currently being detected.

  Specifically, when the inspection result is normal in the second notification state 430, the control unit 406 replaces the notification sound indicating the confirmation result in the normal monitoring state 410 with the detection value exceeding the notification threshold. The notification sound about the detection target is configured to be output from the speaker 8a. That is, the control unit 406 outputs the notification sound to be detected from the speaker 8a instead of the normal notification sound "normal" in the normal monitoring state 410.

  In the case where the inspection result in the second notification state 430 is normal, a different notification sound is set for each detection target.

  When the detection value (WBGT) related to heat stroke prevention exceeds the notification threshold (in the example of FIG. 12, WBGT is equal to or higher than 28 ° C.), the control unit 406 outputs a notification sound in a normal state in the normal monitoring state 410. Instead, a heat stroke warning message (notification sound for heat stroke prevention) is output once.

  When the detection value (absolute humidity, relative humidity, temperature) related to air drying exceeds the notification threshold (in the example of FIG. 13, in the case of the caution state, the first warning state, or the second warning state), the control unit 406 determines Instead of the notification sound at the normal time in the normal monitoring state 410, a drying warning message (a notification sound regarding air drying) is output once.

  The operation when the inspection result is abnormal in the second notification state 430 is the same as that in the normal monitoring state 410. In the second notification state 430, when the inspection result is normal, a notification sound indicating normality may be output similarly to the normal monitoring state 410.

<Long press check>
The operation state in which the long press inspection can be executed is only the normal monitoring state 410. Therefore, during the first notification state 420, the second notification state 430, and the notification by voice sound, even if the switch 9 is pressed long, the long press check is not performed.

(Effect of Fourth Embodiment)
In the fourth embodiment, as described above, when the short press input of the switch 9 is received in the first notification state 420 that exceeds the notification threshold of the notification about gas, the function confirmation operation is not performed, and the notification about the heat stroke prevention is performed. When the input of the switch 9 is received in the second notification state 430 exceeding the notification threshold, the alarm device 400 is configured to execute the function confirmation operation. Thereby, even in the situation where the notification regarding the heat stroke prevention is performed, the function confirmation operation can be executed with priority given to the user's intention (operation input), so that the convenience for the user can be improved. .

  In the fourth embodiment, as described above, when the input of the switch 9 is received during non-notification, the control unit outputs a notification sound (voice message of “normal”) indicating the result of the function check operation. 406 is constituted. Then, the input of the switch 9 is received in the second notification state 430 exceeding the notification threshold of the notification regarding the heat stroke prevention, and when the confirmation result is normal, the heat stroke warning message is replaced with the "normal" voice message. The control unit 406 is configured to output. Thereby, when the function confirmation operation is performed in the second notification state 430 exceeding the notification threshold value of the notification regarding the heat stroke prevention, the heat stroke warning message notifies the user that the confirmation result is normal and the heat stroke prevention message. Notification can also be performed. At this time, a notification of heat stroke prevention can be given as a response to the input operation of the switch 9, so that the user can more reliably recognize the content of the notification by the notification in a state where the user's attention is directed to the alarm 400. be able to.

[Modification]
It should be noted that the embodiments disclosed this time are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description of the embodiments, and includes all modifications within the scope and meaning equivalent to the terms of the claims.

  For example, in the first embodiment, an example is shown in which the present invention is applied to an alarm having a smoke detection unit and a fire alarm function, but the present invention is not limited to this. In the present invention, the smoke detector does not need to be provided in the alarm device.

  Further, in the first to fourth embodiments, the example in which WBGT is used as the heat stroke index for performing the notification regarding the heat stroke prevention is shown, but the present invention is not limited to this. In the present invention, the heat stroke prevention may be notified using a heat stroke index other than WBGT. For example, (dry bulb) temperature and relative humidity may be used as heat stroke indices.

  Further, in the first embodiment, notification (including non-notification) of four stages of heat stroke prevention according to the WBGT is performed based on the notification operation conditions shown in FIG. Although the example of performing the notification in three stages shown in FIG. 12 has been described, the present invention is not limited to this. For example, notification content of two or less steps or five or more steps according to WBGT may be set. Further, another value may be used as the WBGT threshold value (in FIG. 4 and FIG. 12, WBGT 31 ° C., 28 ° C., 25 ° C.) that defines each stage of notification.

  Further, in the first and third embodiments, the example in which the notification content regarding the prevention of heat stroke is determined based on which of the numerical ranges the value of WBGT corresponds to, but the present invention is not limited to this. . In the present invention, the notification content may be determined based on the change tendency of the WBGT. For example, when the WBGT falls within the range of less than 31 ° C. and 28 ° C. or more (region 11b) for 10 minutes or more, it is determined whether the value of WBGT is increasing, and the value of WBGT is increasing. In this case, the notification content may be changed. For example, if the WBGT is in a rising trend continuously for 10 minutes or more, since the WBGT is likely to reach a range of 31 ° C. or more, even if the current WBGT is in a range of less than 31 ° C. and 28 ° C. or more, You may make it change into the notification content corresponding to the range of 31 degreeC or more. Further, in this case, if the current upward trend of the WBGT will continue in the future, a notice of how many minutes to reach the danger level (area 11a) of 31 ° C. or higher may be notified.

  Further, the message content of the voice notification described in the first to fourth embodiments is merely an example, and in the present invention, a message other than the first embodiment may be reported. For example, the detected current temperature and relative humidity may be notified as a voice notification message. Thereby, the user can grasp the danger of heat stroke by objective numerical information.

  In addition, it is said that the resistance to heat stroke greatly varies depending on the user's temperature (body temperature) control function, and that especially elderly people and children need to pay attention to heat stroke because the temperature control function is low. For this reason, when the notification regarding the heat stroke prevention is given by voice notification, a message that calls attention to the elderly or children may be notified.

  In the first and second embodiments, the control is performed so that the notification regarding the heat stroke prevention is performed based on the detection results of the gas detection unit 2 as well as the detection results of the temperature detection unit 3 and the humidity detection unit 4. Although an example in which the unit 6 is configured has been described, the present invention is not limited to this. In the present invention, the notification regarding the heat stroke prevention may be performed based only on the detection results of the temperature detection unit 3 and the humidity detection unit 4.

  Further, in the first to fourth embodiments, the example in which the notification regarding the air drying is performed has been described, but the present invention is not limited to this. In the present invention, the notification regarding the air drying may not be performed. When performing notification regarding air drying, notification operation conditions and notification contents different from the above-described notification operation conditions and notification contents (see FIGS. 6 and 13) may be set.

  Further, in the first to fourth embodiments, as the notification start condition, a state in which each detection result of the gas concentration, the smoke concentration, the WBGT and the absolute humidity corresponds to the notification condition (exceeds the notification threshold) is continuously set to 10 times. An example has been described in which the notification is executed when the time is continued (10 minutes), but the present invention is not limited to this. In the present invention, a notification start condition different from the above may be set. Further, the notification start conditions of the notification about gas, the notification about fire, the notification about heat stroke prevention, and the notification about air drying may be different.

  Further, in the first and second embodiments, the temperature detector is provided with the common temperature detector 3 for temperature compensation and for the notification of heat stroke prevention and air drying. Not limited to this. In the present invention, a temperature detection unit may be separately provided for temperature compensation and for notification of heat stroke prevention and air drying.

  Further, in the first and second embodiments, it has been described that when the detection result of the gas detection unit 2 satisfies a predetermined condition, it is estimated that the combustion appliance CA is being used. Not limited. In the present invention, it may be determined whether or not there is a user in the room based on, for example, a detection result of the humidity detecting unit. When a user is present in the room and performing daily activities, the detection result of the humidity detecting unit fluctuates, such as a rise in humidity as compared with a state where the user is not present in the room. Therefore, only when it is estimated that the user is indoors based on the detection result of the humidity detection unit, the notification regarding the prevention of heat stroke and the air drying may be performed.

  In the first to fourth embodiments, the push-button switch 9 is described as an example of the operation unit, but the present invention is not limited to this. In the present invention, the operation unit may be a toggle switch, or may be other than a switch as long as it can receive a start command of the function check operation of the alarm device. For example, the alarm device may include a wired or wireless controller as an operation unit. In the case of a wireless system, for example, infrared, near field communication (NFC), Wi-Fi (registered trademark), or Bluetooth (registered trademark) may be used. Further, the operation unit may be a signal receiving unit of the above-mentioned wireless system. In this case, for example, the signal receiving unit may receive a command (a command to start a function checking operation) from a user's portable information terminal (such as a smartphone). In addition, the alarm device may include a touch panel type operation unit.
