Problems solved by technology

The reason is that when the above-mentioned antenna is arranged on the front surface side of the circuit board, that is, close to the room, it is necessary to ensure a space for disposing the antenna between the circuit board and the front cover of the fire alarm, which makes it difficult to implement the device. miniaturization
[0006] However, as an adverse effect when the antenna is arranged in the space on the rear surface side of the circuit board, the gain of the antenna may decrease.
The same problem is not limited to fire alarms that detect smoke, but other than fire alarms that detect heat, in wireless devices that transmit or receive signals by wireless, when the degree of freedom in the arrangement of the antenna is small, the above-mentioned problems are common. The problem

no. 1 Embodiment approach ）

[0050] A fire annunciator configured using the wireless device according to the first embodiment of the present invention will be described. The fire alarm 1 uses a battery as a power source, detects smoke, and sends a detection signal through wireless communication using radio waves, such as figure 1 As shown, the fire annunciator 1 is installed on the ceiling surface by, for example, double-sided tape or an adhesive, screws, or the like. in the figure 1 Although the embodiment in which the fire annunciator 1 is installed on the ceiling surface is shown in , the fire annunciator 1 may be installed on a wall surface. figure 1 The illustration shows a situation in which the above-mentioned wireless residential fire alarm 1 communicates wirelessly with the interphone 100 for receiving visitors. Here, the walkie-talkie 100 for visitor reception may be connected to a sub-host or the like in a wired and transmittable manner other than wireless communication, such as a walkie-talk...

[0064] Figure 5 as well as Figure 6 Shown is a fire annunciator configured using the wireless device according to the second embodiment of the present invention. The difference from the fire alarm 1 of the first embodiment which detects smoke is that the fire alarm 50 of this second embodiment detects heat.

[0065] The fire alarm 50 includes a thermal detector 52 , a circuit board 3 , a speaker 4 , an antenna 5 , a battery 6 , a housing 58 , an attachment base 9 , a front cover 10 , a conductor 11 , and the like. also, Figure 6 The state which removed the attachment base 9 and the frame body 58 from the fire annunciator 50 is shown from the rear surface side.

[0066] The antenna 5 and the conductor 11 are formed of linear conductors, and extend along the inner peripheral wall of the housing 10 and the like from the substantially facing edge portions of the circuit board 3 . The antenna 5 is arranged on the rear surface side of the circuit board 3 . The conductor 11 i...

no. 3 Embodiment approach ）

[0081] A human body sensing sensor configured using the wireless device according to the third embodiment of the present invention will be described. The human detection sensor 201 uses a battery as a power source similarly to the fire alarm 1 of the above-mentioned embodiment, and transmits a detection signal through wireless communication using radio waves, such as Figure 9 As shown, the human body sensing sensor 201 is installed on the ceiling by, for example, double-sided tape or adhesive, screws, and the like. A wireless receiving unit for receiving (diagnosing) a detection signal transmitted from the human body sensing sensor 201 is provided in a switch (switch) 202 provided on the wall surface. In addition, the switch 202 is connected to a lighting device 203 installed on the ceiling via an electric wire 204 .

[0082] The switch 202 is, for example, an electronic switch (load control device) using a non-contact switching element such as a triac, and can replace a con...

Abstract

Disclosed is a wireless apparatus which is provided with: an antenna; a circuit board which constitutes a wireless communication circuit having the antenna connected thereto; and a housing, which houses the circuit board, and which is formed by resin molding. A linear conductor is extended from the ground of the circuit board.

Description

technical field [0001] The present invention relates to a wireless device that transmits or receives signals wirelessly. Background technique [0002] Conventionally, a fire alarm that senses smoke and notifies occupants has been widely used as a sensor-applied device installed on a wall or ceiling of a house (for example, refer to Patent Document 1). Such an annunciator includes a smoke detection unit that detects smoke, a speaker that emits an alarm sound, and a circuit board connected to the smoke detection unit and the speaker, and is called a residential fire alarm. The smoke detection unit detects smoke flowing in through the guide unit. In order to efficiently convey the alarm sound to the occupants, the speaker is usually arranged on the front surface side of the fire alarm, that is, close to the room. The circuit board and the loudspeaker are disposed near the indoor of the fire alarm so that the connecting wire connected to the loudspeaker does not hinder the inf...
