The smoke detection unit 5 includes, for example, a light emitting element and a light receiving element, and is configured to output a light receiving amount signal dimmed by smoke on the optical path to the control unit 6. Specifically, the smoke detection unit 5 is based on the amount of received light received in the absence of smoke (light is not dimmed), and based on what percentage of the amount of received light is reduced by smoke on the optical path (dimming rate). To determine the smoke concentration. The smoke detection unit 5 may be of a type that receives scattered light scattered by smoke, for example.

The control unit 6 is composed of a CPU, and controls the detection operation of each detection unit by executing the operation program stored in the storage unit 7, acquires the detection result, and performs a predetermined notification. It is configured to function as a control unit of the alarm device 100 for determining. Further, 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. Further, the lamp 8b is composed of LED lamps of a plurality of colors, and the control unit 6 lights lamps of different colors according to the content of the notification, and uses continuous lighting or blinking at predetermined time intervals. It is configured in. The signal output unit 8c is used to output a notification as an external output signal when the alarm device 100 is connected to an external device (another alarm device).

The alarm 100 includes one switch 9. The switch 9 is, for example, a push button type switch, which receives an input operation and outputs an input signal to the control unit 6. The control unit 6 pauses the voice and the signal by accepting the input operation of the switch 9 during the notification by the voice ringing of the speaker 8a or 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 notify the gas based on the detection result of the gas detection unit 2 and to notify the fire based on the detection result of the smoke detection unit 5. Further, the control unit 6 notifies about 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 notify about air drying based on the detection result by the humidity detection unit 4.

The storage unit 7 acquires thresholds and detection results used for each notification determination of gas notification (gas leak and incomplete combustion gas generation), fire notification, heat stroke prevention notification, and air drying notification. Various information such as a table used for, 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 as detection results from the methane gas sensor and the CO gas sensor of the gas detection unit 2, respectively. Further, the control unit 6 compares the obtained detection concentration with the threshold value stored in advance in the storage unit 7 to see if the concentrations of methane gas and CO gas have reached a predetermined notification level (abnormality determination standard). It is configured to determine the gas concentration by determining whether or not it is present.

Further, the control unit 6 is configured to acquire the ambient ambient temperature and the relative humidity as detection results from the temperature detection unit 3 and the humidity detection unit 4, respectively. Then, the control unit 6 is configured to acquire the heat stroke index based on the detection results of temperature and humidity.

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

WBGT is an index that incorporates temperature, humidity, and radiant heat, and is defined by the following equation (1) indoors (indoor R1) where there is no solar radiation.
WBGT (° C) = 0.7 x wet-bulb temperature (° C) + 0.3 x black bulb temperature (° C) ... (1)
Here, a dedicated measuring instrument 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 (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 region 11a (WBGT = 31 ° C. or higher) is at a "dangerous" level, and it is said that there is a risk of developing heat stroke even during activities of daily living, and elderly people need to be careful even in a resting state. To. The second region 11b from the top (WBGT = 28 ° C or higher and lower than 31 ° C) is at the "strict caution" level, and caution is required even during daily mild daily activities, and caution is also required for room temperature rise. It is said that. The third region 11c from the top (WBGT = 25 ° C. or higher and lower than 28 ° C.) is at the “alert” level, and caution is required when performing moderate or higher living activities such as cleaning and floor polishing. The lowermost region 11d (WBGT = less than 25 ° C.) is regarded as a "caution" level, and although there is generally little risk, it is recommended to be careful when performing strenuous exercise.

The control unit 6 acquires the WBGT as a heat stroke index by collating the temperature and humidity detection results 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 notifying the air drying based on the detection results by the temperature detection unit 3 and the humidity detection unit 4. Has been done.

Absolute humidity can be obtained from the following equation (2) from the gas state equation.
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 air temperature at 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 (table). Based on the above, the control unit 6 acquires the absolute humidity from the temperature and (relative) humidity detection results. The control unit 6 is configured to determine heat stroke / humidity by the above method.

Further, as shown in FIG. 2, the control unit 6 acquires the dimming rate dimmed by the smoke on the optical path as the smoke concentration detection result based on the light receiving amount signal of the light receiving element obtained from the smoke detecting unit 5. It is configured to do. Further, the control unit 6 determines whether or not the smoke concentration has reached the notification level by comparing the obtained smoke concentration with the threshold value stored in advance in the storage unit 7, thereby determining the smoke concentration. It is configured to do.

The control unit 6 notifies the user based on the respective 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 configured to determine. 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 a notification start condition, for example, the control unit 6 acquires each determination result at a predetermined detection timing at 1-minute intervals, and the determination results acquired at 1-minute intervals are continuously 10 times (10 minutes continuously). When the notification conditions are met, it is decided to perform the notification operation. Hereinafter, each determination result and the notification content according to the notification conditions will be described.

<Notice regarding heat stroke prevention>
Regarding the notification regarding 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 the WBGT is 31 ° C. or higher (region 11a), the control unit 6 determines to blink the lamp 8b and perform voice notification. The blinking operation of the lamp 8b, for example, turns on the orange lamp 8b once at 5-second intervals. In addition, the voice notification outputs a message such as "The room is hot. Let's make it well-ventilated and remove water and salt" from the speaker 8a. First, as the initial notification, the voice notification is notified five times at 1-minute intervals. After that, while the state of WBGT of 31 ° C. or higher continues, notification is performed once at 10-minute intervals.

Further, the control unit 6 determines to blink the lamp 8b and perform voice notification even when the WBGT is 28 ° C. or higher and lower than 31 ° C. (region 11b). In this case, the blinking operation of the lamp 8b causes, for example, the orange lamp 8b to be turned on once at intervals of 10 seconds. In addition, the voice notification outputs a message such as "The room is hot. Let's remove water and salt" from the speaker 8a. The voice notification is performed once at 30-minute intervals while the WBGT is continuously in a state of 28 ° C. or higher and lower than 31 ° C.

Further, the control unit 6 determines that only the lamp 8b is turned on when the WBGT is 25 ° C. or higher and lower than 28 ° C. (region 11c). In this case, voice notification is not performed. The lamp 8b, for example, continuously lights the orange lamp 8b.

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

In this way, the control unit 6 changes the content of the notification operation (lamp lighting / blinking, blinking interval, voice notification content, voice notification interval, etc.) according to the notification condition of WBGT (WBGT range of 4 stages). It is configured in.

Here, in the first embodiment, the control unit 6 is configured to acquire the detection result of the gas detection unit 2 in determining the content of the notification regarding the prevention of heat stroke. Then, when the control unit 6 notifies the heat stroke prevention based on the detection results of the temperature detection unit 3 and the humidity detection unit 4, the control unit 6 notifies 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 heat stroke prevention by the output unit 8 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. Is configured to do.

The case where the detection result of the gas detection unit 2 satisfies a predetermined condition is the 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 set predetermined threshold value is exceeded (or falls below). Such a predetermined fluctuation pattern and a predetermined threshold value are set based on, for example, data of detected values (methane gas concentration, CO gas concentration) when using the combustion appliance CA.

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 are monotonous. It shows a fluctuation tendency close to an increase. On the other hand, when there is no gas leak or incomplete combustion, and no combustion appliance CA is used, the detected value is stable and shows a vicinity of 0. On the other hand, when the combustion appliance CA is used, such as during cooking, the detected value is lower than that when gas leakage or incomplete combustion occurs, and fluctuates irregularly. Therefore, whether or not the combustion appliance CA is used by using the fluctuation pattern of the detected value at the time of using the combustion appliance CA acquired in advance, or by using the upper threshold value and the lower threshold value according to the fluctuation range. It is possible to estimate. When the combustion appliance CA is used, other gases are generated and the temperature and humidity are increased. Therefore, the detection results of these other gas concentrations, temperature and humidity may be combined for judgment.

In the first embodiment, when the detection result of the gas detection unit 2 satisfies a predetermined condition (when it is presumed that the combustion appliance CA is used), the control unit 6 sets the control unit 6 as shown in FIG. It is configured to perform at least one of notification for prompting the stop of the combustion appliance CA in use, increase in the frequency of notification regarding heat stroke prevention, and increase in the frequency of determination of notification regarding heat stroke prevention.

The notification prompting the stop of the combustion appliance CA in use is, for example, a voice notification message such as "The temperature of the room is rising, so please 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 (WBGT 31 ° C. or higher and 28 ° C. or higher and lower than 31 ° C.) shown in FIG.

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

The increase in the frequency of judgments regarding the prevention of heat stroke is a change in the conditions for starting notifications. For example, in the normal time, when the notification operation is executed when the determination result acquired at 1-minute intervals meets the notification condition (any of the four-stage WBGT range) 10 times in a row, the control unit 6 sets The notification start condition is changed so that immediate notification is performed when the notification 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 (detection 10 times) to the frequency of every 1 minute (detection once).

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

Here, research results have been reported that high and low absolute humidity affect the survival rate of influenza virus in relation to air drying. 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%, and 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. ^If it is ³ or less, the 6-hour survival rate is said to be approximately 0%. The lower the 6-hour survival rate, the less likely it is to be infected with influenza virus. In other words, 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 7 g / m ³ or less, the control unit 6 blinks the lamp 8b and determines to perform voice notification. The blinking operation of the lamp 8b, for example, turns on the blue lamp 8b once at 5-second intervals. In addition, the voice notification outputs a message such as "Let's keep the room dry" from the speaker 8a. The voice notification will continue once at 30-minute intervals while the absolute humidity is 7 g / m ³ or less.

Further, when the absolute humidity is 11 g / m ³ or less, the control unit 6 blinks only the lamp 8b and decides not to perform voice notification. The blinking operation of the lamp 8b, for example, turns on the blue lamp 8b once at intervals of 10 seconds.

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

The above are the notification conditions and notification contents regarding heat stroke prevention and air drying. Each threshold value and notification condition for these notifications are stored in the storage unit 7 in advance. In addition, when performing voice notification in the notification regarding heat stroke prevention and air drying, the control unit 6 makes the notification volume smaller than the notification volume at the time 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 regarding heat stroke prevention and air drying from giving the user an unnecessarily alert feeling.

<Other notifications>
Regarding the notification regarding 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 standard) stored in the storage unit 7. When it is determined that the signal has been reached, it is determined to perform a predetermined notification operation. The notification operation is, for example, voice notification (gas leak, incomplete combustion has occurred) and lamp lighting (red, yellow).

Regarding the notification regarding fire, the control unit 6 performs a predetermined notification operation when the smoke concentration (dimming rate) reaches a predetermined notification level (abnormality determination standard) stored in the storage unit 7. decide. Regarding the notification regarding this fire, in the first embodiment, the control unit 6 changes at least one of the abnormality determination standard and the determination frequency by the smoke detection unit 5 based on the detection result of the humidity detection unit 4. 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.

Regarding the abnormality determination standard and determination frequency by the smoke detection unit 5, the control unit 6 acquires the effective humidity based on the current and past humidity detection results stored in the storage unit 7, and responds to the value of the effective humidity. Change at least one of the abnormality judgment criteria (notification level) and judgment frequency. The effective humidity is the humidity obtained by integrating the relative humidity of the past several days represented by the following formula (3), and is used as an index showing the degree of drying of wood.
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 meteorological stations and the like. H ₀ , H ₁ , H ₂ , ..., H _n are the average humidity n days ago, respectively, and H ₀ is the humidity of the day. Generally, it is said that the risk of fire increases when the effective humidity is about 50% to 60%.

When the acquired effective humidity is lower than a predetermined threshold value (for example, 60%), the control unit 6 lowers the abnormality determination standard (notification level) by the smoke detection unit 5. For example, normally, assuming that the notification level of the determination result by the smoke detection unit 5 is set to a dimming rate of 10%, when the effective humidity is below the threshold value, the control unit 6 sets the notification level to the dimming rate. Reduce to 7.5%.

Regarding the determination frequency, for example, in the normal state, the control unit 6 performs a notification operation when the determination result acquired at 1-minute intervals meets the notification condition 10 times in a row (when the notification level is reached). Execute. On the other hand, when the effective humidity is lower than the threshold value, the control unit 6 changes so that the immediate notification is performed when the notification condition is satisfied even once. That is, by changing the notification start condition, the control unit 6 determines the frequency of determining whether or not to perform notification from the normal frequency of once every 10 minutes (detection 10 times) to 1 minute (detection once). Increase to every frequency. As a result, it is possible to detect a fire earlier when it is dry and has a high risk of fire.

Next, regarding the distinction between smoke and water vapor, when water vapor is generated during cooking in the kitchen, the water vapor that reaches the optical path of the smoke detection unit 5 dims the light, so that smoke and water vapor are mistaken. There is a possibility of detection. The generation of such water vapor usually causes the fluctuation of the extinction rate in the case of water vapor to be more rapid than the fluctuation of the smoke concentration (dimming rate) due to smoke at the time of a fire. It is possible to distinguish between smoke and water vapor based on the fluctuations.

In the first embodiment, the control unit 6 discriminates between smoke and water vapor based on the temporal fluctuation of the detection result, and also the detection result (dimming rate) of the smoke detection unit 5 and the detection result of the humidity detection unit 4. To distinguish between smoke and water vapor. For example, when the smoke concentration is determined to be water vapor based on the time-dependent fluctuation of the smoke concentration detection result, the control unit 6 considers the detection result of the humidity detection unit 4 and the humidity is continuously set to a threshold value for a predetermined time. When it is (for example, 70%) or more, it is determined that it is water vapor. As a result, it is possible to discriminate between smoke and water vapor more accurately, and it is possible to suppress the occurrence of erroneous detection.

(Alarm notification judgment and notification operation)
Next, with reference to FIG. 7, the control operation related to the notification determination and the notification operation of the alarm device 100 according to the first embodiment will be described. 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 the gas detection timing, and if it is not the gas detection timing, proceeds to step S4. When 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 detects them in the storage unit 7. Remember 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 the execution of the notification operation when the state in which the detection result reaches the notification level of the notification regarding the gas continues 10 times in succession. The control unit 6 sets the notification flag for notification regarding gas to on (notification execution) or off (notification execution) 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, and if it is not the smoke detection timing, proceeds to step S7. When 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 concentration (dimming rate) as the detection result, and stores the storage unit 7. Store the detection result. In step S6, 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 (smoke alarm determination process). That is, the control unit 6 determines the execution of the notification operation when the state in which the detection result reaches the notification level of the notification regarding the fire continues 10 times in succession. The control unit 6 sets the notification flag for fire notification to on (notification execution) or off (notification execution) and stores it in the storage unit 7.

In step S7, the control unit 6 determines whether or not it is the temperature / humidity (temperature and humidity) detection timing, and if it is not the temperature / humidity detection timing, the process proceeds to step S11. In the case of 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 stores the detection result in the storage unit 7.

In step S10, the control unit 6 determines whether or not to notify the 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 also acquires the absolute humidity based on the detected temperature and humidity. Subsequently, the control unit 6 determines whether or not the WBGT and the absolute humidity satisfy the notification start condition, and determines whether or not to perform the notification operation. That is, the control unit 6 determines the execution of the notification operation when the state in which the detection result (WBGT) corresponds to any of the notification conditions shown in FIG. 4 continues 10 times in succession. Similarly, the control unit 6 determines the execution of the notification operation when the state in which the detection result (absolute humidity) corresponds to any of the notification conditions shown in FIG. 6 continues 10 times in succession. The control unit 6 stores the notification flag of the notification regarding heat stroke prevention and the notification flag of the notification regarding air drying in the storage unit 7 by turning them on (notification execution) or off (notification execution).

In step S11, the control unit 6 performs a notification content determination process for 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 which notification condition the latest WBGT corresponds to in FIG. 4 (Which of the regions 11a to 11d the WBGT corresponds to). , Determines the content of the notification operation (lamp lighting / blinking, blinking interval, voice notification content, voice notification interval, etc.). Regarding the notification regarding air drying, the control unit 6 determines, for example, the execution of the notification operation and the content of the notification according to which notification operation condition shown in FIG. 6 corresponds to the latest absolute humidity. Regarding the notification regarding gas and the notification regarding fire, the notification operation and the notification content are determined according to the respective notification conditions.

In step S12, the control unit 6 performs voice ringing processing, and executes a notification voice (message), a buzzer sound, or the like according to the determined notification content. If the notification content does not include voice notification (such as when the WBGT is less than 28 ° C.), voice notification is not performed.

In step S13, the control unit 6 performs lamp display processing and executes lighting / blinking of the lamp 8b according to the determined notification content. If the content of the notification does not include lighting of the lamp (such as when the WBGT is less than 25 ° C.), the notification by the lamp display is not performed.

In step S14, the control unit 6 performs external output processing, and when an externally connected device (other alarm device or the like) is present, the control unit 6 outputs an external output signal according to the determined notification content from the signal output unit 8c. After the above processing, the process returns to step S1 and these steps S1 to S14 are repeated to control the operation of the alarm device 100.

(Processing for changing the conditions for notification regarding heat stroke prevention)
Next, with reference to FIG. 8, a process for changing the condition of notification regarding heat stroke prevention based on the detection result of the gas detection unit 2 will be described.

In step S21 of FIG. 8, the control unit 6 reads out 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 or not the detection result of the gas detection unit 2 satisfies a predetermined condition. The method of judgment is as described above. When it is determined that the predetermined condition is satisfied (it is presumed that the combustion appliance CA is used), the control unit 6 changes the notification start condition / notification content of the notification regarding heat stroke prevention in step S23. The changes are shown in FIG. 4, for example.

As a result, the notification start condition of the notification determination in step S10 of 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 presumed 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, when it is determined in step S22 that the predetermined condition is not satisfied after the notification start condition / notification content is changed in step S23 (that is, the use of the combustion appliance CA is stopped). If), the changed notification start condition / notification content is restored.

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

In step S31 of FIG. 9, the control unit 6 reads the detection result (relative humidity) of the humidity detection unit 4 from the storage unit 7 for a predetermined period (current and past several days). 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 or not the effective humidity has fallen below a predetermined threshold value (for example, 60%). When it is determined that the effective humidity is below a predetermined threshold value, the control unit 6 changes the notification condition / notification start condition (abnormality determination standard, determination frequency) of the notification regarding the fire in step S34. The changes are as described above. As a result, the notification condition / notification start condition in the smoke alarm determination process in step S6 of FIG. 7 is changed.

On the other hand, when it is determined that the effective humidity is equal to or higher than a predetermined threshold value, 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.

(Water vapor judgment processing)
Next, with reference to FIG. 10, the 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 will be described.

In step S41 of FIG. 10, the control unit 6 reads out the detection result (smoke concentration) 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 time-dependent concentration fluctuation of the read smoke concentration data for a predetermined time. If it is determined that it is not due to water vapor, the control unit 6 ends the process as it is.

When it is determined that the detection result is due to water vapor, the control unit 6 reads out 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 or not the read humidity is continuously equal to or higher than a predetermined threshold value (for example, 70%) for a predetermined time.

If it is equal to or higher than a predetermined threshold value, 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 the 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 due to water vapor, the smoke concentration is rapidly reduced, and notification (misinformation) caused by water vapor is prevented.

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

The condition change process of FIGS. 8 and 9 and the water vapor determination process of FIG. 10 may be performed in parallel with the notification determination and the control of the notification operation of FIG. 7, or in the control flow of FIG. May be incorporated as part of.

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

In the first embodiment, as described above, a temperature detection unit 3 provided in the alarm body 1 to detect the temperature of the room R1 and a humidity detection unit 3 provided in the alarm body 1 to detect the humidity of the room R1. 4 and the alarm body 1 are provided to notify the gas based on 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 is provided. By providing a control unit 6 and an output unit 8 for notifying heat stroke prevention based on the detection result of the humidity detection unit 4, the notification of gas such as gas leakage is notified based on the detection result of the gas detection unit 2. In addition to being able to do this, the detection results (temperature and humidity) of the temperature detection unit 3 and the humidity detection unit 4 can be used to obtain information (WBGT) that guides the risk of developing heat stroke. Information on heat stroke prevention can be provided based on the information. As a result, in addition to the notification of gas such as gas leak, it is possible to appropriately notify the situation to be noted in the user's daily living environment such as heat stroke. Further, since the alarm device 100 that notifies a gas leak or the like generally has a high notification ability and can make the user surely recognize the gas leak or the like, the alarm device 100 having such a high notification ability has heat stroke. By adding the function of notification regarding prevention, it is possible to make the user more surely recognize the notification regarding heat stroke prevention, unlike the thermo-hygrometer which promotes the prevention of heat stroke whose notification ability is not so high.

Further, in the first embodiment, as described above, the heat stroke prevention is notified 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. As a result, it can be estimated that the combustion appliance CA is used from the detection result of the gas detection unit 2, and it is possible to determine whether or not the temperature and humidity of the room R1 are likely to rise further. As a result, the state of the room R1 can be grasped more concretely based on the detection result of the gas detection unit 2, so that the notification regarding the prevention of heat stroke can be performed more appropriately.

Further, in the first embodiment, as described above, when the notification regarding 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 a predetermined condition. When the condition is satisfied, at least one of notification for prompting the stop of the burning appliance CA in use, increase in the frequency of notification regarding heat stroke prevention, or increase in the frequency of determination of notification regarding heat stroke prevention is performed. As a result, if the detection result of the gas detection unit 2 satisfies a predetermined condition presumed that the combustion appliance CA is used, the combustion appliance CA is configured to be stopped, and the indoor R1 is renewed. It is possible to suppress the rise in temperature and humidity. Further, if the notification frequency for heat stroke prevention is increased (the number of notifications is increased or the notification interval is shortened), the heat stroke prevention notification can be more reliably transmitted to the user. In addition, if the frequency of judgments regarding heat stroke prevention is increased, notifications regarding heat stroke prevention can be promptly responded to when the room temperature and humidity further increase and the risk of heat stroke increases. It can be done early.

Further, in the first embodiment, as described above, in addition to the notification regarding gas and the notification regarding heat stroke prevention, the notification regarding 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. As a result, in addition to notifying the user about gas leakage and heat stroke prevention, the user can be further encouraged to control the humidity to prevent air drying, so that a more multifunctional alarm device 100 can be provided. As a result, it is possible to reduce the risk of influenza infection by maintaining an appropriate humidity.

Further, in the first embodiment, the smoke detection unit 5 is further provided as described above. As a result, not only gas leak notification but also fire notification can be performed by detecting smoke when a fire occurs. Then, in the first embodiment, at least one of the abnormality determination standard and the determination frequency is changed by the smoke detection unit 5 based on the detection result of the humidity detection unit 4, or the detection result and humidity of the smoke detection unit 5 are changed. Smoke and water vapor are discriminated from each other based on both the detection results of the detection unit 4. If at least one of the abnormality judgment standard and the judgment frequency is changed by the smoke detection unit 5 based on the detection result of the humidity detection unit 4, the abnormality judgment standard is lowered (high sensitivity) especially when the dry state continues. Since it is possible to increase the frequency of judgment, 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, the humidity rise when steam (steam) is generated is detected. Therefore, it is possible to suppress erroneous detection of smoke detection and perform fire detection (notification) more appropriately. As a result, it is possible to provide a multifunctional and highly functional alarm device 100 having an appropriate (highly functionalized) fire alarm function as well as notification of gas leakage and heat stroke prevention.

[Second Embodiment]
Next, the second embodiment will be described with reference to FIGS. 2 and 11. 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, a bedroom, or the like will be described. .. The same configuration as that of the first embodiment is illustrated with the same reference numerals as those of the first embodiment, and the description thereof will be omitted.

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

The alarm device 200 according to the second embodiment is provided mainly for performing a fire alarm, unlike the alarm device 100 according to the first embodiment. As the alarm device 200 (fire alarm) for living rooms and bedrooms, if there is no combustion appliance CA in the room R2 to be installed, the gas leak (fuel gas) notification function is not always necessary. On the other hand, for example, when a heating appliance such as a gas heater is installed in the indoor R2, the gas leak notification function is useful. Regarding the incomplete combustion notification function, when a fire breaks out, carbon monoxide is often generated before smoke is generated, so it is also useful for early detection of fire, and it is a fire alarm for living rooms and bedrooms. Is also very useful.

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

The other configurations of the alarm device 200 in the second embodiment are the same as those in the first embodiment.

(Effect of the second embodiment)
Even in the alarm device 200 (fire alarm) for living rooms and bedrooms as in the second embodiment, the gas is notified based on the detection results of the temperature detection unit 3, the humidity detection unit 4, and the gas detection unit 2. At the same time, among the gas detection unit 2, the temperature detection unit 3, and the humidity detection unit 4, the control unit 6 and the output unit that notify the heat stroke prevention based on the detection results of at least the temperature detection unit 3 and the humidity detection unit 4. By providing the item 8, in addition to the notification regarding gas such as gas leak, it is possible to appropriately notify the situation to be noted in the user's daily living environment such as heat stroke.

Further, the 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. 12 and 13. In this third embodiment, other specific examples of the notification regarding heat stroke prevention and the notification regarding air drying will be described. Since the device configuration is the same as that of the first embodiment, the description thereof will be omitted.

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

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

<Alert state>
The notification 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 by 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 heat stroke warning message is, for example, "The room is hot. Let's keep it well ventilated and remove water and salt."

In the alert state 310, automatic voice notification (automatic notification) with the passage of time and voice notification at the time of switch input when the switch 9 is input are set.

In the automatic notification, the heat stroke warning message is continuously output a plurality of times (three times) as one notification operation. In the automatic notification, the notification interval is set to 30 minutes, and the number of additional notifications (upper limit) is set to 2 times (2 turns). That is, if the notification threshold is continuously exceeded for 30 minutes after the first notification, the second notification operation is performed. After that, if the notification threshold is continuously exceeded for another 30 minutes, the third notification operation is performed. After the first notification and the second additional notification, no additional voice notification by automatic notification is performed.

As for the voice notification when the switch is input, the heat stroke warning message is output only once. The voice notification at the time of switch input is performed with a smaller notification effect (1 time output) than the voice notification by automatic notification (3 times continuous output). This is because the user's attention is directed to the alarm device 300 when the switch 9 is input, so that the notification can be sufficiently transmitted to the user.

<Caution state>
The notification condition of the caution state 320 is that the WBGT is 28 ° C. or higher and lower than 31 ° C. (region 11b, see FIG. 3). In this case, in principle, the control unit 306 notifies the lamp 8b without performing the voice notification. The lamp 8b blinks unlike the alert state 310. As the blinking operation, for example, it is turned on once at intervals of 5 seconds.

Attention state 320 does not automatically notify by voice. In the caution state 320, as an exception, voice notification at the time of switch input is set. The voice notification at the time of switch input is the same as the alert state 310.

<Normal state>
In the third embodiment, the state where the WBGT is lower than 28 ° C. (regions 11c and 11d, see FIG. 3) is set as the normal state 330 in which the notification is not performed. In the normal state 330, no notification is performed by either the lamp 8b or the speaker 8a.

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

Unlike the first embodiment, in the third embodiment, in addition to absolute humidity, relative humidity and temperature notification thresholds are set as notification conditions for notification regarding 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 voice 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 the 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 alert operation having a higher notification effect is performed, and the alert level is relatively high (second alert state). In the state 340), the 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 is at bedtime or absent. Absolute humidity, relative humidity and temperature increase as the user acts in room R1 (R2). Therefore, by appropriately setting the notification thresholds of absolute humidity, relative humidity, and temperature, each detected value can be set to exceed the notification threshold of the second alert state 340 when the user is inactive (at bedtime) or absent. .. In the third embodiment, three notification thresholds are set as the notification conditions for the second warning state 340: absolute humidity 7 g / m ³ or less, relative humidity 40% or less, and temperature less than 10 ° C.

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

In the second alert state 340, voice notification by automatic notification is not performed. Therefore, it is suppressed that the notification voice is output when the user is sleeping or absent.

In the second alert state 340, as an exception, voice notification at the time of switch input is set. As for the voice notification when the switch is input, the dry warning message is output only once. The speaker 8a outputs a dryness warning message. The dryness warning message is, for example, the 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 user's activity in the room R1 (R2), at least one of the notification thresholds of absolute humidity, relative humidity and temperature is relaxed from the notification threshold of the second alert state 340.

Specifically, as notification conditions for the first warning state 350, three notification thresholds are set: absolute humidity 7 g / m ³ or less, relative humidity 40% or less, and temperature 10 ° C. or higher and lower than 30 ° C. There is. Therefore, in the third embodiment, the temperature threshold is relaxed in the first alert state 350 rather than in the second alert state 340, and the alert level is set lower.

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

In the first alert state 350, automatic voice notification (automatic notification) with the passage of time and voice notification at the time of switch input are set.

In the automatic notification, a dry warning message is continuously output a plurality of times (three times) as one notification operation. In the automatic notification, the notification interval is set to 30 minutes, and the number of additional notifications (upper limit) is set to 2 times (2 turns). As for the voice notification when the switch is input, the dry warning message is output only once.

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

<Normal state>
In the third embodiment, a state in which the absolute humidity is higher than 7 g / m ³ is set as a normal state 370. The normal state 370 is not notified by either the lamp 8b or the speaker 8a.

(Effect of Third Embodiment)
In the third embodiment, as described above, regarding the notification regarding air drying, in the case of the first warning state 350, the second notification operation including the voice notification is performed, and the second warning level is higher than that of the first warning state 350. In the case of the alert state 340, the control unit 306 and the output unit 8 are configured so as to perform the first notification operation that does not include the voice notification. Here, the degree of dryness of the indoor R1 (R2) is low humidity (dryness) during inactivity such as when absent or sleeping. Therefore, by setting the dry state as the second alert state 340, which occurs only during inactivity such as when the user is absent or sleeping, unnecessary notification during the user's inactivity can be suppressed, which is convenient for the user. Can be improved.

(Modified example of the third embodiment)
In the third embodiment, an example of performing the first notification operation that does not include voice notification in the case of the second alert state 340 is shown, but instead of the first notification operation that does not include voice notification, no notification is 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 of changing the operation at the time of receiving the input of the switch according to the detection target currently being detected will be described. Since the device configuration is the same as that of the first embodiment, the description thereof will be omitted.

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 start command for the function confirmation operation of the alarm device 400 in addition to pausing the voice ringing.

(Switch input reception)
First, the reception of the input operation by the switch 9 will be described. In the fourth embodiment, one switch 9 is configured to be able to accept 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 the pressing time of the switch 9. The control unit 406 accepts the first input operation (short press input) when the press duration of the switch 9 is a short time less than a predetermined threshold value (for example, 3 seconds). Further, the control unit 406 accepts a second input operation (long press input) when the press duration of the switch 9 is longer than a predetermined threshold value (for example, 3 seconds).

(Operation when receiving switch input)
The switch 9 receives a voice ringing stop command. When the control unit 406 receives a short press input of the switch 9 during the notification by the voice ringing of the speaker 8a, the control unit 406 pauses the voice ringing. Long press input is invalid during notification by voice ringing. Regardless of the type of notification, the control unit 406 stops voice for all types of notification. The types of voice notifications are mainly gas leak notifications, incomplete combustion notifications, fire notifications, heat stroke prevention notifications, and air drying notifications.

In the fourth embodiment, the switch 9 receives the start command of the function confirmation operation. The function confirmation operation is a confirmation operation (inspection operation) of whether or not the function provided in the alarm is working normally.

The function confirmation operation includes a function confirmation operation (short press inspection) when a short press input is accepted and a function confirmation operation (long press inspection) when a long press input is accepted. The control unit 406 receives a voice ringing stop command and a short press inspection (function confirmation operation) execution command by a common first input operation (short press input).

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

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 tests the notification operation for various notifications such as gas leak notification, incomplete combustion notification, fire notification, heat stroke prevention notification, and air drying notification. In the long press inspection, the control unit 406 performs notification by the output unit 8 (notification voice output of the speaker 8a, lighting / blinking of the lamp 8b, 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 or not the notification operation has been normally executed.

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

As shown in FIG. 14, the operating state of the alarm device 400 includes a normal monitoring state 410, a first notification state 420, a second notification state 430, and notification by the above-mentioned voice ringing (not shown).

The normal monitoring state 410 is a non-notification state in which the detection value of each detection unit does not exceed any notification threshold value (a state in which none of the notification conditions is 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 of the notification thresholds. However, the first notification state 420 and the second notification state 430 exclude during notification by voice ringing. The first notification state 420 and the second notification state 430 correspond to, for example, a state in which notification is being performed only by the lamp 8b and a state in which voice is stopped after voice 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 leak are set as detection targets. In the second notification state 430, heat stroke prevention and air drying are set as detection targets.

The control unit 406 makes the operation of the switch 9 at the time of receiving the input different for each of these operating states. As described above, during the notification by the voice ringing, the voice ringing is temporarily stopped by the short press input, so that the function confirmation 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 status>
In the normal monitoring state 410 (during non-notification), the control unit 406 executes a short press inspection (function confirmation operation) in response to the reception of the short press input. In this case, the control unit 406 outputs a notification sound indicating a confirmation result by the function confirmation operation.

When the inspection result is normal, the control unit 406 outputs a notification sound indicating that it is normal from the speaker 8a. The normal notification sound 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 result is abnormal is output. The notification sound when an abnormality is detected is, for example, a voice message such as "It is a malfunction. Please contact the store."

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

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

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

Further, in the fourth embodiment, the notification of the confirmation result by the short press inspection is also different depending on the operating state. The control unit 406 notifies the confirmation result by different notification operations 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 has the detected value exceeding the notification threshold instead of the notification sound indicating the confirmation result in the normal monitoring state 410. It is configured to output a notification sound about the detection target 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.

As the notification sound when 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 value (in the example of FIG. 12, when the WBGT is 28 ° C. or higher), the control unit 406 makes a normal notification sound in the normal monitoring state 410. Instead, a heat stroke warning message (a notification sound related to heat stroke prevention) is output once.

When the detected value (absolute humidity, relative humidity, temperature) related to air drying exceeds the notification threshold value (in the example of FIG. 13, in the case of the caution state, the first alert state, or the second alert state), the control unit 406 is used. , A drying warning message (notification sound related to air drying) is output once instead of the normal notification sound in the normal monitoring state 410.

In the second notification state 430, the operation when the inspection result is abnormal 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 that the inspection result is normal may be output as in the normal monitoring state 410.

<Long press inspection>
The operating state in which the long press inspection can be executed is normally only the monitoring state 410. Therefore, during the first notification state 420, the second notification state 430, and the notification by voice ringing, even if the switch 9 is pressed for a long time, the long press inspection is not executed.

(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 exceeding the notification threshold of the notification regarding gas, the function confirmation operation is not executed and the notification regarding 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. As a result, even in a situation where a notification regarding 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 (a voice message of "normal") indicating the confirmation result by the function confirmation operation. It constitutes 406. Then, the input of the switch 9 is accepted in the second notification state 430 that exceeds the notification threshold of the notification regarding heat stroke prevention, and if the confirmation result is normal, a heat stroke warning message is sent instead of the "normal" voice message. The control unit 406 is configured to output. As a result, when the function confirmation operation is executed in the second notification state 430 that exceeds the notification threshold value of the notification regarding heat stroke prevention, the heat stroke warning message notifies that the confirmation result is normal and the heat stroke prevention is performed. Notification can also be performed. At this time, since the heat stroke prevention notification can be performed as a response to the input operation of the switch 9, the notification content is more reliably recognized by the notification in a state where the user's attention is directed to the alarm device 400. be able to.

[Modification example]
It should be noted that the embodiments disclosed this time are exemplary in all respects and are not considered to be restrictive. The scope of the present invention is shown by the scope of claims rather than the description of the above-described embodiment, and further includes all modifications within the meaning and scope equivalent to the scope of claims.

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

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

Further, in the first embodiment, based on the notification operation conditions shown in FIG. 4, notification (including non-notification) regarding four-stage heat stroke prevention according to WBGT is performed, and in the third embodiment, FIG. Although the example of performing the three-step notification shown in No. 12 is shown, the present invention is not limited to this. For example, the notification content of 2 steps or less or 5 steps or more may be set according to the WBGT. Further, another value may be used as the WBGT threshold value (WBGT 31 ° C., 28 ° C., 25 ° C. in FIGS. 4 and 12) that defines each stage of notification.

Further, in the first and third embodiments, an example is shown in which the notification content regarding heat stroke prevention is determined based on which of the numerical ranges the WBGT value corresponds to, but the present invention is not limited to this. .. In the present invention, the notification content may be determined based on the changing tendency of the WBGT. For example, when WBGT continuously corresponds to a range of less than 31 ° C. and 28 ° C. or higher (region 11b) for 10 minutes or longer, it is determined whether or not the value of WBGT is on an upward trend and is on an upward trend. The notification content may be changed in some cases. For example, if the WBGT tends to rise continuously for 10 minutes or more, the WBGT is likely to reach the range of 31 ° C or higher. Therefore, even if the current WBGT is in the range of less than 31 ° C and 28 ° C or higher, The notification content may be changed to correspond to the range of 31 ° C. or higher. Further, in this case, if the current upward trend of WBGT continues in the future, a notice of how many minutes later the danger level (region 11a) of 31 ° C. or higher may be reached may be notified.

Further, the content of the voice notification message 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 notified. For example, the detected current temperature and relative humidity may be notified as a voice notification message. As a result, the user can grasp the risk of heat stroke from objective numerical information.

In addition, resistance to heat stroke varies greatly from person to person depending on the temperature (body temperature) control function of the user, and it is said that especially elderly people and children need to be careful about heat stroke because the temperature control function is low. Therefore, when the notification regarding the prevention of heat stroke is performed by voice notification, a message calling attention to the elderly or children may be notified.

Further, in the first and second embodiments, control is performed so as to notify heat stroke prevention 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. Although an example constituting the part 6 is shown, the present invention is not limited to this. In the present invention, notification regarding 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, an example of notifying air drying is shown, but the present invention is not limited to this. In the present invention, it is not necessary to give notification regarding air drying. When the notification regarding air drying is performed, the notification operation conditions and notification contents different from the above 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, the states in which the detection results of the gas concentration, the smoke concentration, the WBGT and the absolute humidity correspond to the notification conditions (exceed the notification threshold) are continuously 10 An example is shown in which the notification is executed when the number of times (10 minutes) is continued, 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 regarding gas, the notification regarding fire, the notification regarding heat stroke prevention, and the notification regarding air drying may be different.

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

Further, in the first and second embodiments, it has been shown that when the detection result of the gas detection unit 2 satisfies a predetermined condition, it is presumed that the combustion appliance CA is 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, the detection result of the humidity detection unit. When a user exists in the room and performs daily activities, the detection result of the humidity detection unit fluctuates, for example, the humidity rises as compared with the state where the user is absent in the room. Therefore, the notification regarding heat stroke prevention and air drying may be performed only when it is estimated that the user is indoors based on the detection result of the humidity detection unit.

Further, in the first to fourth embodiments, the push button type switch 9 is shown 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 a switch other than the switch as long as it can accept the start command of the function confirmation operation of the alarm device. For example, an alarm may include a wired or wireless controller as an operating unit. In the case of a wireless system, for example, infrared rays, near field communication (NFC), Wi-Fi (registered trademark) or Bluetooth (registered trademark) may be used. Further, the operation unit may be the above-mentioned wireless signal receiving unit. In this case, for example, the signal receiving unit may be configured to receive a command (a command to start a function confirmation operation) from a user's mobile information terminal (smartphone, etc.). Further, the alarm device may include a touch panel type operation unit.
