FIG. 13 is a block diagram schematically showing a conventional smoke detection device 9 of a type connected to an intake pipe and an exhaust pipe. FIG. 13(A) shows the appearance of the smoke detection device 9 , and FIG. 13(B) shows the state in which the cover 911 constituting the front portion of the casing 91 included in the smoke detection device 9 is removed. In addition, FIG. 13(C) is a top view of the smoke detection device 9, and FIG. 13(D) is a bottom view of the smoke detection device 9.

The smoke detection device 9 includes a housing 91 and a display unit 92 as components visible from the outside. The display unit 92 has, for example, a touch screen, displays various information to the user, and functions as a user interface that accepts the user's touch operation. The cover 911 is provided with an opening (window) corresponding to the position of the display unit 92. Even with the cover 911 attached, the display unit 92 can be visually confirmed from the outside of the housing 91, and the display unit can also be inspected. 92 for touch operation.

The smoke detection device 9 is connected to an intake pipe 7 as a pipe that guides air from the monitored space S1 to the smoke detection device 9 , and as a pipe that guides air from the smoke detection device 9 to the exhaust destination space S2 . Exhaust pipe 8.

In addition to the display unit 92, the housing 91 also accommodates a smoke detection unit 93, a power supply unit 94, and a data processing unit 95. In addition, the display unit 92, the smoke detection unit 93, the power supply unit 94, and the data processing unit 95 are respectively held in predetermined positions by the housing 91. As a method for holding these components in the housing 91, for example, any method such as bolt fastening, inserting, hooking with hooks, connection with surface fasteners, adhesion with double-sided tape, etc. can be used.

The smoke detection unit 93 has a sensor 931, an air suction part 932, and an exhaust part 933. Sensor 931 detects smoke in the air. The sensor 931 is, for example, a photoelectric smoke sensor, which includes a light-emitting part, a light-receiving part, and a determining part. The light-receiving part receives the light reflected by the particles in the air emitted from the light-emitting part, and the determining part uses the received light based on the received light. The intensity is used to determine whether there is smoke in the air. However, the method by which the sensor 931 detects smoke is not limited to this. The sensor 931 is arranged in an accommodation space formed in the housing of the smoke detection unit 93 .

The suction part 932 is connected to the suction pipe 7 and is a member that forms a flow path of air from the space S1 to be monitored for smoke toward the accommodation space of the sensor 931 . The exhaust part 933 is connected to the exhaust pipe 8 and is a member that forms a flow path of air from the accommodation space of the sensor 931 toward the exhaust destination space S2.

The power supply unit 94 supplies electric power to the components of the smoke detection device 9 including the smoke detection unit 93 and which require electric power.

The data processing unit 95 performs processing using the data generated by the smoke detection unit 93 . Examples of processing performed by the data processing unit 95 include storage of data, transmission of data to an external device, determination of the presence or absence of smoke based on the data, and a display unit for reporting notifications such as warnings according to the determination results of the presence or absence of smoke. 92 control, etc., but not limited to this.

In addition, in addition to the display unit 92, the smoke detection unit 93, the power supply unit 94, and the data processing unit 95, the housing 91 also accommodates, for example, a transmission cable for supplying power from the power supply unit 94 to the smoke detection unit 93, etc. The communication cables and other components used for data communication between the data processing unit 95 and the smoke detection unit 93 are omitted in FIG. 13 .

As shown in FIG. 13(B) , the casing 91 has a piping hole H1 and a piping hole H2. The piping hole H1 allows the intake pipe to pass through while the smoke detection unit 93 is held at a predetermined position of the casing 91. 7, and the piping hole H2 serves as a hole through which the exhaust pipe 8 can pass.

The smoke detection device 9 having the above structure detects the smoke particles in the air guided by the suction pipe 7 and reaching the smoke detection device 9 when smoke is generated in the monitored space S1, for example, by the display unit 92 Reports a warning notifying smoke generation, or sends a warning message to a terminal device used by an administrator. In addition, the method of reporting a warning by the smoke detection device 9 is not limited to this. For example, the smoke detection device 9 may be equipped with a sound emitting part such as a buzzer or a speaker to emit a sound or voice indicating a warning, or the smoke detection device 9 may be equipped with a warning. Light, warning by lighting of warning light, etc.

As shown in FIG. 13 , the smoke detection device 9 configured as above can be used when the suction pipe 7 is located on the upper side of the smoke detection device 9 and the exhaust pipe 8 is located on the lower side of the smoke detection device 9 . However, in the case of the suction pipe When the positions of 7 and exhaust pipe 8 are opposite, it cannot be used as it is. Figure 14 shows a situation where the suction pipe 7 is located below the installation position of the smoke detection device 9 and the exhaust pipe 8 is located above the installation position of the smoke detection device 9. The smoke detection device 9 is arranged as shown in Figure 13 The configuration direction is the opposite of up and down.

In this case, as shown in FIGS. 14(A) and 14(B) , the information displayed on the display unit 92 is upside down. In addition, for example, by having the display unit 92 have the function of rotating information 180 degrees for display, as shown in FIG. 14(C) , even if the information displayed on the display unit 92 is not turned upside down, there is still a user interface problem. The position is lower than the smoke detection device 9, and the operability is reduced. In addition, when the manufacturer's name (for example, "XYZ" shown in FIG. 14 ) is formed on the cover 911 of the housing 91 by printing or the like, it is unavoidable that the information formed on the cover 911 is turned upside down.

In order to solve the above problem, for example, as shown in FIG. 15 , it may be considered to manufacture the smoke detection unit 93 in which the positions of the suction part 932 and the exhaust part 933 are opposite to the smoke detection unit 93 shown in FIG. 13 . In this case, it is necessary to separately prepare two types of smoke detection units 93 having different configurations.

In addition, for example, as shown in FIG. 16 , it is possible to consider that the smoke detection unit 93 having the same configuration as the smoke detection unit 93 shown in FIG. 13 is mounted on the housing in an arrangement direction that is upside down from the arrangement direction shown in FIG. 13 . 91 on. In this case, it is necessary to prepare a separate housing 91 whose positions of the piping hole H1 and the piping hole H2 are different from those of the housing 91 shown in FIG. 13 .

In view of the above, the present invention provides a smoke detection device that can be used without the need for large-scale component replacement even if the connected suction pipe and exhaust pipe are in different positional relationships. [Means used to solve problems]
