(Prior Art) Conventionally, opening and closing of windows in a room have been performed manually.

(Problems to be solved by the invention) However, since the window once opened needs to be manually closed again when it reaches a predetermined temperature, the work of closing the window becomes troublesome at bedtime. In addition, it was a problem in crime prevention.

In view of the above conventional problems, an object of the present invention is to provide an automatic window closing device that automatically closes a window when the room temperature is lower than a set temperature or when an intruder is near the window. To provide.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a driving means for moving an opening / closing portion of a window in a closing direction, a first sensor for detecting a temperature in a room having the window, and an outdoor unit. And a second sensor which is installed in the vicinity of the window and detects whether or not an object exists near the window, and the first sensor detects a temperature equal to or lower than a set temperature, or the second sensor It is characterized in that a control means for operating the driving means when the presence of an object is detected is provided.

(Operation) According to the present invention, when the room temperature is lower than or equal to the set temperature through the first sensor, or when it is determined that there is an intruder near the window through the second sensor, The opening / closing part of the open window is closed by the driving means.

(Embodiment) FIGS. 1 to 5 show an embodiment of the present invention.
Is a rectangular window frame, 2 is an opening / closing part interposed in the window frame 1, that is, a pair of sliding windows, 3 is a window stand that supports the window frame 1,
4 is a veranda provided outside each sliding window 2; 5 is a controller of drive means 6 described later provided at an upper corner of the window frame 1; 6 is each sliding window provided on the window stand 3; It is a drive means for driving one of the two.

The lower frame 21 of each of the sliding windows 2 is, as shown in FIG.
Each of them has an H-shaped cross section, a glass plate 22 is supported on the upper portion, and wheels 24 are rotatably attached to both ends of the lower portion in the longitudinal direction via axles 23. Further, two guide rails 12 are provided on the lower frame 11 of the window frame 1, and the wheels 24 are rotatably guided on the guide rails 12. In addition, a third portion is provided between the wheels 24 of the lower frame 21.
A mounting plate 25 for mounting a rack, which will be described later, as shown in the figure.
Is provided.

Two pairs of vertical frames 41 and 42 located on both sides of the balcony 4
As shown in FIG. 4, an infrared sensor 7 having two light emitting portions 71 opposed to one vertical frame 41 and two light receiving portions 72 opposed to the other vertical frame 42 is attached thereto. There is.

As shown in FIGS. 2 and 3, the drive means 6 includes a motor 61 and a transmission mechanism 62 for transmitting the rotational force of the motor 61.
It consists of and. The transmission mechanism 62 is a rack 63,
The pinion 64, the bevel gears 65 and 66, the reduction gear 67, and the motor gear 68 are sequentially meshed with each other. Also, the rack 6
3 is bonded to the lower surface of the attachment plate 25 of the sliding window 2, the motor gear 68 is connected to the main shaft 61a of the motor 61, and the rotation of the motor 61 moves the sliding window 2 in the closing direction. It has become. Incidentally, 69 is the pinion 6
4 is a support base for rotatably supporting 4.

FIG. 5 is a circuit diagram showing the control means of the drive means 6. Here, 81 is a variable resistor whose set value changes based on the temperature setting dial 51 attached to the controller 5, 82 is a thermistor for detecting the room temperature, 83 is a comparator, 84 is an OR gate, and 85 is a transistor. , 86
Is a relay, 86a is a relay contact, 87 is an alarm buzzer circuit, 88a, 88b and 88c are resistors, and 89 is a sliding window 2.
It is a window switch that turns off when is closed.

The comparator 83 inputs the voltage between the variable resistor 81 and the resistor 88a and the voltage between the thermistor 82 and the resistor 88b, respectively, and outputs a high level signal when the voltage on the thermistor 82 side is high. To be done. Output signals from the comparator 83 and the infrared sensor 7 are input to the OR gate 84. The transistor 85 has its base side connected to the OR
To the output terminal of the gate 84, the collector side is connected to the power supply Vd via the resistor 88c and the emitter side is connected to the relay 86, and the relay contact 86a of the relay 86 is inserted into the power supply circuit of the motor 61 of the drive means 6. ing. The alarm buzzer circuit 87 is adapted to issue an alarm based on the detection signal from the infrared sensor 7.

According to the present embodiment, for example, the temperature set in the room is set to 25 ° C. by the temperature setting dial 51, the sliding window 2 is opened, and the user sleeps. After that, when the room temperature becomes lower than 25 ° C., the voltage on the thermistor 82 side changes to the variable resistor 81.
The voltage becomes higher than the voltage on the side, the high level signal is input from the comparator 83 to the OR gate 84, and the high level signal is output from the OR gate 84 to the transistor 85. As a result, the relay 86 is driven, the relay contact 86a is closed, and the motor 61 of the driving means 6 is driven. This motor 6
The sliding window 2 is moved in the closing direction via the transmission mechanism 62 by the driving of No. 1 and the window switch 8 is closed by closing the sliding window 2.
9 is turned off and the drive of the motor 61 is stopped.

When a person invades the veranda 4, the infrared sensor 7 detects the invader and outputs a high-level signal to the OR gate 84 to move the sliding window 2 in the closing direction, as described above. Further, the alarm buzzer circuit 87 is driven by the detection signal of the infrared sensor 7 and sounds an alarm buzzer (not shown).

(Effect of the Invention) As described above, according to the present invention, when the room temperature becomes lower than the set temperature or when the intruder is near the window, the open window is closed. Therefore, it has an advantage that it does not require a troublesome work such as closing the window while sleeping and has a crime prevention effect.
