Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an automatic air-conditioning and ventilation system linked to a rice cooker, and in particular, to an automatic air-conditioning and ventilation system that is linked to a rice cooker and, in particular, automatically exhausts steam discharged from a rice cooker to the outside using a ventilation fan. This article relates to an automatic air conditioning and ventilation system linked to a rice cooker.

[Prior Art] Conventionally, a rice cooker and a ventilation fan have been installed at separate locations and used independently.

That is, the ventilation fan is operated and stopped by manual operation using a switch installed on the ventilation fan body or at a separate position away from the ventilation fan body. In addition, rice cooking using a rice cooker is performed using a switch or the like provided on the main body of the rice cooker.

However, when rice is cooked using a rice cooker, steam is normally discharged into the room from the steam outlet of the rice cooker. Therefore, it is necessary to exhaust this steam outside.

Therefore, in order to exhaust this steam outside, conventional methods have been to ventilate the room by operating a ventilation fan each time or leaving it running at all times to prevent steam from entering the room. It was being prevented.

[Problems to be Solved by the Invention] In the conventional air conditioning ventilation system as described above, the rice cooker and the ventilation fan are not linked to each other, and the rice cooking operation by the rice cooker and the ventilation operation by the ventilation fan are performed separately and independently. It was being done. For this reason, in a rice cooker that operates a ventilation fan each time the rice is cooked, the user may forget to start the ventilation fan. Then, the ventilation fan remained in a stopped state and the room was not ventilated, so the steam generated during cooking caused water vapor to drift around the kitchen, causing condensation and odor throughout the room. In particular, many rice cookers in recent years have built-in timer mechanisms, and cooking rice before cooking in the morning causes condensation and odors.

On the other hand, even if I had the ventilation fan running, I sometimes forgot to turn it off after cooking. In this case, even though ventilation has ended and the ventilation fan does not need to be operated, it continues to operate, resulting in a waste of electricity.

In addition, if the ventilation fan is kept running all the time, the ventilation effect is sufficient, but the maintenance costs are high.
It was extremely uneconomical.

For this reason, the ventilation fan and rice cooker are operated in conjunction with each other,
It was desired to have an air conditioning ventilation system that can ventilate the room only when steam is discharged from the rice cooker.

In addition, for example, a ventilation system that controls the operation of a ventilation fan in conjunction with some other detection means, etc.
It is also described in No. 1820 and Utility Model Application No. 62-179401M.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rice cooker-linked automatic air-conditioning/ventilation system that can control the operation of a ventilation fan depending on the state of steam discharged from the rice cooker and can automatically discharge steam outdoors.

The rice cooker-linked automatic air conditioning ventilation system of this embodiment is configured as described above, and the rice cooker (7) and the ventilation fan (1) operate in conjunction with each other, and the air is discharged from the rice cooker (7). Steam (13) is automatically discharged outdoors using a ventilation fan (1). This operation will be explained below.

When the rice cooker (7) enters rice cooking operation by timer operation or manual operation and the rice cooking progresses gradually, steam (13) comes to be discharged from the steam outlet (12) of the rice cooker (7). Then, the steam temperature of this steam (13) is PVDF
is detected by a steam detection sensor (14) consisting of an infrared sensor using pyroelectricity, etc., and this detection signal is sent to the amplifier (16) of the rice cooker control device (8) via a cable (15).
) is entered. Then, it is amplified by this amplifier (16) to become the waveform signal @vS shown in (a> in Fig. 3), which is input to the voltage comparator (17). (threshold voltage), and when VT < VS, an "H" command is sent to the power line carrier signal transmission circuit (20) to drive the ventilation fan drive motor (32) of the ventilation fan (1). ''In response to the command, the power line carrier signal transmission circuit (20) performs predetermined modulation to generate a power line carrier signal, and the coupling capacitor (20) generates a power line carrier signal.
21), (22>, the plug (9) and the outlet (5), and the signal is transmitted to the power line (6) in a form superimposed on the commercial power supply. This signal transmission method is well known for power line carrier telephones, etc. This power line carrier signal is transmitted to all outlets connected to the power line (6) in the home.

On the other hand, since the ventilation fan (1) is also connected to the outlet (4) of the power line (6) in the same household, the power line carrier signal is transmitted to the ventilation fan control device (1) of the ventilation fan (1) via the power line (6).
2) is also transmitted. That is, the power line carrier signal is transmitted to the power line carrier signal receiving circuit (27) via the coupling capacitors (25) and (26). The power line carrier signal receiving circuit (27) demodulates this signal, identifies whether it is a signal to operate the ventilation fan (1), and issues a ventilation fan drive command to the motor control circuit (28). Upon receiving this command, the motor control circuit (28) operates the light emitting element (30) of the phototriac coupler (29). As a result, the triac (31) goes from the photo 1 to the triac coupler (29) to the first photo coupler (29).
When the is turned on, the goo 1~ of the triac (33)
A current is supplied to the resistor (34) through the resistor (34).

Then, the triac (33) is turned on, the ventilation fan drive motor (32) is driven, and the operation of the ventilation fan (1) is started. By operating this ventilation fan (1), the rice cooker (
The steam (13) discharged from 7) is discharged outside.

Also, the rice cooking operation of the rice cooker (7) is finished and the steam (13)
When the discharge of gas stops, the detection signal from the steam detection sensor (14) disappears, and the output of the voltage comparator (17) becomes “L”.
There will be 11 directives. Then, the power line carrier signal transmission circuit (2
Transmission of power line carrier signals from 0) is also stopped. As a result, the power line carrier signal receiving circuit (
27), and the ventilation fan drive command from the power line carrier signal receiving circuit (27) to the motor control circuit (28) stops. As a result, the triac (33) turns off, the ventilation fan drive motor (32) stops,
Eventually, the ventilation fan (1) stops operating. Ventilation ends when the ventilation fan (1) stops operating.

In addition, the motor control circuit (28) of the ventilation fan control device (2)
If a delay timer is built into the ventilation fan drive motor (32)
It is also possible to set the driving stop timing to an arbitrary time after a certain period of time has elapsed after the discharge of steam (13) from the rice cooker (7>) has stopped (see FIG. 3(C)).

In this way, in the rice cooker-linked automatic air conditioning and ventilation system of this embodiment, the steam (13
) is detected by a steam detection means consisting of a steam detection sensor (14), and the rice cooker control device ( 8) generates a power line carrier signal by the signal generating and transmitting means, transmits this signal to the ventilation fan (1) via the power line (6), and receives this power line carrier signal by the ventilation fan control device (2). The signal is received by the circuit (27), and the motor control circuit (28) of the ventilation fan control device (2) controls the drive of the ventilation fan drive motor (32), thereby controlling the operation of the ventilation fan (1). .

Therefore, the ventilation fan (1) and the rice cooker (7) operate in conjunction with each other, and the operation of the ventilation fan (1) can be controlled according to the discharge status of steam (13) from the rice cooker (7), allowing the steam to be vented outdoors. can be automatically discharged.

As a result, when steam (13) is being discharged from the rice cooker (7), the ventilation fan (1) can always be in operation,
Because the room can be ventilated, you can use the rice cooker (7) as usual.
There is no need to manually operate the ventilation fan (1) each time you cook rice.

Therefore, there is no need to forget to start operating the ventilation fan (1) when cooking rice, or forget to turn off the ventilation fan (1) after cooking rice. - Therefore, condensation and odor generation throughout the room can be suppressed, and power consumption is also eliminated. Also,
Since there is no need to keep the ventilation (1) running all the time, it is extremely economical.

Moreover, the signal generation and transmission means of the rice cooker (7) and the ventilation fan (1)
) There is no need for special wiring for signal transmission between the ventilation fan control device (2), so even when used in a house,
It is practical and can be used as is without any special construction.

In general, the motor impunity circuit (28) of the ventilation fan control device (2)
) with a built-in delay timer, the ventilation fan drive motor (32
) can be set to any time after a certain period of time has elapsed after the steam (13) from the rice cooker (7) stops discharging, ensuring that residual moisture and odors are completely removed from the room. This allows the room to be ventilated more reliably.

Next, the rice cooker-linked automatic air-conditioning and ventilation system of the second invention will be explained. However, since FIG. 1 and FIG. 3 are common to the embodiment of the first invention described above, explanation thereof will be omitted here.

FIG. 4 is a schematic circuit diagram that does not show the control circuit configuration of the rice cooker-linked automatic air-conditioning and ventilation system that is necessary in an embodiment of the second invention. In addition, in the drawings, the same reference numerals and symbols as in the embodiment of the first invention described above are the same or corresponding constituent parts as in the embodiment of the above first invention, so the explanation thereof will not be repeated here. Omitted.

In the figure, (37) is an infrared carrier signal transmitting circuit that generates an infrared carrier signal by predetermined modulation in response to a command from the voltage comparator (17), and (38) is connected to this infrared carrier signal transmitting circuit (37). It is a light emitting element consisting of a light emitting diode or the like. (39) is a photoelectric conversion element consisting of a photo 1 to a transistor, etc., and (40) is an infrared carrier signal receiving circuit that receives and demodulates an infrared carrier signal with the photoelectric conversion element (39).

The rice cooker-linked automatic air conditioning and ventilation system of this embodiment is configured as described above, and transmits and receives infrared carrier signals between the light emitting element (38) and the photoelectric conversion element (39), and the rice cooker (7) ) and the ventilation fan (1) operate in conjunction with each other, and the steam (13) discharged from the rice cooker (7) is transferred to the ventilation fan (1).
This system uses a system to automatically discharge the air outdoors. This operation will be explained below.

The detection signal from the vapor detection sensor (14) is transferred to the amplifier (16).
) and the voltage comparator (17) to compare the voltages is the same as in the first embodiment of the invention. Voltage comparator (1
In 7), vS and VT (threshold voltage) are compared, and when VT < VS, the "T1" command to drive the ventilation fan drive motor (32) of the ventilation fan (1) is sent to the infrared carrier signal transmission circuit (37). ). This “N
Upon receiving the et command, the infrared carrier signal transmission circuit (37) performs encoding and predetermined modulation necessary for infrared carrier to generate an infrared carrier signal, causing the light emitting element (38) to emit infrared light. This encoded infrared general transmission signal is converted into a photocurrent by a photoelectric conversion element (39), and demodulated by an infrared carrier signal receiving circuit (40). Then, the code is deciphered, it is determined whether the signal is for operating the ventilation fan (1), and a ventilation fan drive command is sent to the motor control circuit (28). Based on this command, the motor control circuit (28) drives the ventilation fan drive motor (32). Note that the operation of this motor control circuit (28) driving the ventilation fan drive motor (32) is the same as in the embodiment of the first invention described above.
The explanation thereof will be omitted here.

Also, the rice cooking operation of the rice cooker (7) is finished and the steam (13)
When the discharge of vapor stops, the detection signal from the vapor detection sensor 4 (14) disappears, and the infrared light emission of the light emitting element (38) stops. As a result, the signal transmission to the ventilation fan control device (2) is also stopped, and finally, the operation of the ventilation fan (1>) is stopped.

In addition, in the case of this embodiment as well, by incorporating a delay timer in the motor control circuit (28) as in the first invention, the time to stop driving the ventilation fan drive motor (32) can be determined by the timing from the rice cooker (7). It can be set at any time after a certain period of time has elapsed since the discharge of steam (13) stopped (see FIG. 3(C)).

In this way, in the rice cooker-linked automatic air conditioning and ventilation system of this embodiment, the steam (13
) is detected by a vapor detection means consisting of a vapor detection sensor (14), and upon receiving this detection signal, an amplifier (16), a voltage comparator (17), an infrared carrier signal transmission circuit (37), and a light emitting element (3B) are activated. An infrared carrier signal is generated by the signal generating and transmitting means consisting of the rice cooker control device (8), this signal is emitted in infrared by the light emitting element (38), and this infrared carrier signal is sent to the ventilation fan control device @ (2).

) with a built-in delay timer, the ventilation fan drive motor (32
) can be set to any desired timing, so residual moisture, residual odor, etc. can be completely discharged to the outside, and indoor ventilation can be performed more reliably.

[Effects of the Invention] As explained above, the rice cooker-linked automatic air conditioning and ventilation system of the first invention detects the steam discharged from the rice cooker with the steam detection means, receives this detection signal, and uses the signal generation and transmission means. A power line carrier signal is generated and transmitted via the power line, and the ventilation fan control device receives this power line carrier signal to control the operation of the ventilation fan, thereby operating the ventilation fan according to the state of steam discharge from the rice cooker. Since steam can be automatically discharged outdoors, there is no need to manually operate the ventilation fan each time you cook rice in the rice cooker, and there is no need to keep the ventilation fan running at all times. Therefore, you will no longer forget to start the ventilation fan when cooking rice, or forget to turn off the ventilation fan after cooking.
Condensation and odor throughout the room are suppressed, and power consumption is eliminated, making it extremely economical. Moreover, there is no need for special wiring for signal transmission between the signal generation and transmission means of the rice cooker and the ventilation fan control device of the ventilation fan, so no special construction is required when using it in a house that has already been constructed. It can be used as is without any modification.
