Description

Heater and Ventilating Device

The present invention relates to a heating device and a ventilation device. More specifically, the present invention relates to a technique for starting or stopping the operation of the ventilation device in conjunction with the heating start or heating stop of the heating device.

BACKGROUND ART A technique for starting or stopping a ventilation device is known in conjunction with a heating start or a heating stop of a heating device. In order to realize this technique, a conventional heating apparatus includes a detector for detecting heating start or heating stop, a transmitter for transmitting an infrared signal for activating the ventilation device or an infrared signal for stopping operation toward the ventilation device, and When the heating start or the heating stop is detected (hereinafter referred to as "heating start and stop detection"), the transmitter has a transmission control unit for transmitting an infrared signal for starting the ventilation device or an infrared signal for stopping the operation. .

The ventilator includes an infrared signal receiver, and starts operation when receiving an infrared signal for activating the ventilator, and stops operation when receiving an infrared signal for activating the ventilator.

In this kind of interlocking technology, in order to use an infrared signal, it is necessary to prevent the transmission and reception of the infrared signal by interrupting the passing route of the infrared signal.

Therefore, the method of providing a transmission part in the upper surface of a heating apparatus is proposed. In this manner, the infrared signal transmitted upward from the heater reaches the receiver of the ventilator. On the other hand, the method of providing a transmission part in the front of a heating apparatus is also proposed. In this manner, the infrared signal transmitted forward from the transmitter hits the operator or the like in front of the heating apparatus and is reflected, and the reflected infrared signal reaches the receiver of the ventilator.

In the case of the conventional heating apparatus, since the transmitting unit transmits the infrared signal only once when the heating start or stop is detected, there is a possibility that the transmitting / receiving failure may occur even in both of the above-described methods in which the transmitting unit is installed on the top or front of the heating apparatus. There is this.

In the method of installing the transmitter on the upper surface of the heating apparatus, the operator bends forward when the heating start or stop is detected so that the operator's head is located on the upper side of the heating apparatus or the operator extends his arm above the heating apparatus. In this case, the infrared signal transmitted at the time of heating start / stop detection may be blocked by the operator's head or arm and may not reach the receiver of the ventilator.

Moreover, in the system in which the transmitter is provided in front of the heating apparatus, if the operator is not in a predetermined position at the time of heating start / stop detection, the infrared signal may not be properly reflected, and thus may not reach the receiver of the ventilation apparatus.

The present invention can reliably transmit and receive an infrared signal between a heating device and a ventilation device even when the operator is in a position or posture that temporarily interrupts the transmission and reception of an infrared signal at the time of heating start or stop detection. It aims to realize the present technology.

The heating apparatus according to the present invention includes a detection unit for detecting a heating start or a heating stop, a transmitter for transmitting an infrared signal for operating the ventilation device or an infrared signal for stopping the operation, and a heating start for the detection unit; A timer for measuring the elapsed time from when the heating stop is detected, and when the detection unit detects heating start or heating stop, the transmitter sends an infrared signal for starting the ventilation device or an infrared signal for stopping the operation; In addition, it characterized in that it comprises a transmission control unit for causing the transmitter to re-send the same infrared signal when the predetermined elapsed time is measured by the timer.

Here, the "heating device" includes a gas stove, a gas stove, an electric stove, a microwave oven, or a small instantaneous water heater. In addition, a "calling part" may be provided on the front surface or the upper surface of a heating apparatus, and may be provided in the other side surface. "Towards the ventilation apparatus" includes the case where it aims directly, and the case where it aims using reflection. Moreover, it is preferable that "the predetermined | prescribed elapsed time" is for 3 second-5 second.

According to the heating apparatus according to the present invention, even when an operator temporarily takes a position or posture that obstructs the transmission and reception of an infrared signal when the heating start or the heating stop is detected (heating start / stop detection). Since the infrared signal is re-sent when a predetermined time elapses from the start / stop detection time, the infrared signal can be reliably transmitted and received between the heating device and the ventilation device.

Preferably, the transmission control unit causes the same infrared signal to be re-sent continuously every predetermined time even after the predetermined elapsed time is measured.

In this case, the transmission time intervals of the infrared signals may all be the same, or may change over time.

According to the heating apparatus according to the present invention, even when the operator temporarily moves to a position where the transmission or reception of an infrared signal is interrupted at the time of heating start or heating stop, infrared rays are spaced at a time interval from the time of heating start or heating stop. Since the signal is repeatedly transmitted, the infrared signal can be transmitted and received more reliably between the heating device and the ventilation device.

In addition, the present invention realizes a novel ventilation device. The ventilator includes a receiving unit for receiving an infrared signal transmitted from a heating device, and a receiving control unit for disabling reception of the same infrared signal which is subsequently re-sent from the heating device after receiving the infrared signal from the receiving unit. .

According to the ventilator according to the present invention, once the infrared signal is received, the reception of the infrared signal re-sent by the heating apparatus is subsequently invalidated, so that power consumption due to the reception can be reduced. In addition, there is an advantage in that the ventilator that sounds a buzzer when receiving can prevent duplication of the buzzer.

Fig. 3 is a diagram showing the configuration of transmitting and receiving infrared signals between the gas stove and the range hood according to the present embodiment.

As shown in Fig. 3, inside the gas furnace 22, micro switches (MS) 27a to 27d corresponding to the ignition / extinguishing switches 26a to 26d shown in Fig. 1 are connected to the switch detection section 40. have. One of the micro switches 27a to 27d is turned on in this switch detecting section 40 (the circuit composed of the switch detecting section 40 and the microswitch 27 is turned on) or the micro switches 27a to 27d) It is possible to detect that all are turned off (the circuit composed of the switch detecting section 40 and the micro switch 27 is turned off). That is, the heating start at which the heating of one of the furnace parts 24a to 24c and the roaster part 24d is started, or the heating stop time at which the heating of all the furnace parts 24a to 24c and the roaster part 24d is stopped. Can be detected. This switch detection section 40 is connected to the transmission control section 42. This transmission control section 42 is connected to two transmission LEDs 44a and 44b (an example of an infrared light emitting element) connected in parallel. The outgoing LED 44a is provided in the first transmitter 28a shown in FIG. 1, and the outgoing LED 44b is provided in the second transmitter 28b. The transmission control section 42 includes an oscillation circuit and the like not shown, and an infrared signal carrying an operating signal or a stop signal of the ventilation fan 36 in the infrared rays from the transmission LEDs 44a and 44b as shown in the operation example described later. Send as. In addition, the operation signal and the stop signal are pulse signals of different patterns, respectively. The transmission control section 42 is connected to the timer 43 and uses the dry battery 45 as the power source.

Inside the range hood 30, two receiving LEDs 48a and 48b (an example of an infrared light receiving element) for receiving infrared signals from the transmitting LEDs 44a and 44b are connected in parallel.

These reception LEDs 48a and 48b are connected to the reception control unit 52. The buzzer 53 is connected to the reception control unit 52. The reception control unit 52 extracts a driving signal or a stop signal from the infrared signal and outputs a motor control signal which is a pulse signal of a pattern corresponding to each signal. This motor control signal is transmitted to the motor control unit 56 connected to the reception control unit 52. The motor control unit 56 is connected to a motor 58 and to an external commercial power supply 57. The motor controller 56 drives and stops the motor 58 in response to the received motor control signal. The motor 58 is connected to the ventilation fan 36, and the ventilation fan 36 is started and stopped in response to the driving and stopping of the motor 58. As shown in FIG.

(First operation example)

Subsequently, a first operation example of the gas furnace 22 and the range hood 30 according to the present embodiment will be described with reference to FIGS. 4 and 5. 4 is a flowchart showing a first operation example of the gas stove according to the present embodiment, and FIG. 5 is a flowchart showing an operation example of the range hood.

First, the operation of the gas furnace 22 will be described.

When any one of the furnace parts 24a to 24c or the roaster part 24d is ignited in the gas furnace 22 shown in FIG. 1, that is, any of the micro switches MS 27a to 27d shown in FIG. When one is turned on, this is detected by the switch detection part 40 of the gas furnace 22 (step S10). Then, the switch detector 40 transmits a heating start detection signal, which is a pulse signal of a unique pattern, to the transmission controller 42. Upon receiving this signal, the transmission control unit 42 loads the "medium" operation signal of the ventilation fan 36 in the infrared to display two transmission LEDs 44a and 44b (two transmission units 28a and 28b). In step S20, control is sent. That is, first, an infrared signal (operation signal) is sent out when the heating start is detected.

After that, the timer 43 connected to the transmission control unit 42 measures the time from when the detection of any one of the micro switches 27a to 27d is turned on (at the time of heating start detection). Then, when the time elapses for 3 seconds (step S30), the transmission control section 42 again carries the "medium" operation signal of the ventilation fan 36 in the infrared so that the two transmission LEDs 44a and 44b can be transmitted. It controls (step S40). That is, the infrared signal (operation signal) is re-sent after 3 seconds have elapsed from the start of the heating start detection.

In addition, even if any microswitch is turned on, if there is at least one other microswitch already turned on, the "middle" operation signal is not sent (step S10). This is because the "mid" operation signal of the ventilation fan 36 is transmitted when another micro switch is turned on, and therefore, it is assumed that the ventilation fan 36 is already operating when a micro switch is turned on.

Subsequently, when all of the furnace parts 24a to 24c shown in FIG. 1 or the roaster 24d are extinguished, that is, when all of the micro switches MS 27a to 27d shown in FIG. 3 are turned off, this is a switch. It is detected by the detection part 40 (step S50). Then, the switch detection unit 40 transmits a heating stop detection signal, which is a pulse signal of a unique pattern, to the transmission control unit 42. The transmission control unit 42 receiving this signal controls the transmission signal to be transmitted by two transmission LEDs 44a and 44b (two transmission units 28a and 28b) by placing the stop signal of the ventilation fan 36 in the infrared ( Step S60). That is, first, an infrared signal (stop signal) is sent out when the heating stop is detected.

After that, the timer 43 connected to the transmission control unit 42 measures the time from when the micro switches 27a to 27d are all detected to be turned off (at the time of heating stop detection). Then, when the time elapses for 3 seconds (step S70), the transmission control section 42 again carries the stop signal of the ventilation fan 36 in the infrared to control the transmission of the two transmission LEDs 44a and 44b ( Step S80). That is, the infrared signal (stop signal) is re-sent after 3 seconds have elapsed from the heating stop detection.

In addition, even if any micro switch is OFF, the stop signal is not sent when any other micro switch is ON (step S50). This means that if another micro switch is OFF, the other micro switch is turned on. This is because it is inappropriate to stop the ventilation fan 36 because the operation of the working portion corresponding to the above is continued.

Subsequently, the operation of the range hood 30 will be described.

When the infrared signal is received by the reception LEDs 48a or 48b of the range hood 30 (step S110), it is determined by the reception controller 52 whether the infrared signal is a "medium" operation signal or a stop signal (step S120). ). When the infrared signal is the "medium" operation signal, it is determined by the reception control unit 52 whether the ventilation fan 36 is already "medium" in operation (step S130). If the ventilation fan 36 has not yet been operated "middle", it is controlled by the reception control unit 52 so as to "bounce" to the buzzer 53 and sound the reception buzzer (step S140). Then, the motor control signal corresponding to the "medium" operation signal is transmitted to the motor control unit 56 to drive the motor 58 to start the "medium" operation of the ventilation fan 36 (step S150). On the other hand, when the ventilation fan 36 is already in "middle" operation (step S130), the "middle" operation signal received by the reception LEDs 48a and 48b is invalidated (step S160), and the reception buzzer does not sound. Do not.

On the other hand, when the infrared signal received by the reception LEDs 48a and 48b is a stop signal (step S120), it is determined by the reception controller 52 whether the ventilation fan 36 is already stopped (step S170). ). When the ventilation fan 36 is not stopped yet, the reception control unit 52 controls the " beep " to the buzzer 53 to sound the reception buzzer (step S180). Then, the motor control signal corresponding to the stop signal is transmitted to the motor control unit 56 to stop the motor 58 to stop the "middle" operation of the ventilation fan 36 (step S190). On the other hand, when the ventilation fan 36 is already stopped (step S170), the stop signal received by the reception LEDs 48a and 48b is invalidated (step S200), and the reception buzzer does not sound.

When the range hood 30 is operated in this way, it is possible to prevent the reception buzzer sounding repeatedly for the same infrared signal (a driving signal if the first received infrared signal is a driving signal and a stop signal if the driving signal is stopped). That is, since the ventilation fan 36 makes the reception buzzer sound only at the time when the operation of the ventilation fan 36 is initially started or stopped, the operator 60 ensures that the operation time of the ventilation fan 36 is started or stopped. can do.

According to the first operation example, when the operator 60 is positioned as shown in FIG. 2 within the irradiation range of the infrared signal transmitted from the transmitter 28 at the start of heating and stop detection, the transmitted infrared signal is transmitted. Strikes the operator 60. The infrared signal that strikes the operator 60 is reflected and irradiated in the direction of the range hood 30 provided above the gas stove 22. When the infrared signal is received from the first receiving unit 33 provided in the front center of the range hood 30 or the second receiving unit 35 provided therein, the ventilation fan 36 is configured according to the above-described transmission / reception configuration. The operation starts or stops.

In addition, even when the operator 60 temporarily leaves within the irradiation range of the infrared signal transmitted at the start of heating and stop detection, the infrared signal is transmitted again 3 seconds after the start of heating and stop detection. When the operator 60 is located within the irradiation range of the infrared signal, the transmitted infrared signal strikes the operator 60. When the infrared signal hit by the operator 60 is reflected and irradiated in the direction of the range hood 30 installed above the gas stove 22 and received by the first receiver 33 or the second receiver 35, the above-described transmission is performed. • The operation of the ventilation fan 36 is started or stopped by the configuration of the reception.

Even if the operator 60 is temporarily displaced within the irradiation range of the infrared signal, the operator 60 is sure that the ignition / fire extinguishing switch 26 provided in the working body 23 is operated. Since it is hard to think that it stays, if the infrared signal is re-sent after 3 seconds, which is the approximate time required for the ignition operation or the digestion operation, it is assumed that the infrared signal strikes the operator 60 with a very high probability.

As described above, according to the first operation example, even when the operator 60 is in a position or posture that temporarily interrupts the transmission and reception of the infrared signal at the time of heating start and stop detection, 3 seconds from the time of heating start and stop detection. Since the infrared signal is re-emitted when the elapsed time, the infrared signal can be reliably transmitted and received between the gas cooker 22 and the range hood 30. In other words, it is possible to securely start or stop the operation of the ventilation fan 36 of the range hood 30 in conjunction with the ignition / fire extinguishing switch 26 of the gas stove 22.

(Second operation example)

Subsequently, a second operation example will be described with reference to FIG. 6. 6 is a flowchart showing a second operation example of the gas furnace according to the present embodiment. The second operation example is a modification of the first operation example, and differs from the first operation example in the following points.

In the second operation example, after the "mid" operation signal of the ventilation fan 36 is transmitted (step S20) at the start of heating start detection, the "mid" operation is again performed 3 seconds after the start of heating start detection (step S30). The operation of sending a signal (step S40) is repeated three times (step S42). Similarly, after sending the stop signal of the ventilation fan 36 at the time of detecting the heating stop (step S60), the operation of sending the stop signal again 3 seconds after the detection of the heating stop (step S70) (step S80) is performed. The process is repeated three times (step S82).

The operation of the range hood 30 is the same as the operation shown in FIG. 5 described in the first operation example.

According to the second operation example, even when the operator 60 is in a position or posture that temporarily interrupts the transmission and reception of the infrared signal at the time of heating start / stop detection, the infrared ray is detected every three seconds from the time of heating start / stop detection. Since the signal is re-sent three times, the infrared signal can be transmitted and received more reliably between the gas stove 22 and the range hood 30. That is, it is possible to more reliably start or stop the operation of the ventilation fan 36 of the range hood 30 in conjunction with the ignition / fire extinguishing switch 26 of the gas stove 22.

In addition, in the second operation example, the infrared signal is transmitted four times in total, three times every three seconds thereafter at the time of heating start / stop detection. In this case, a receiver is further provided on the upper surface of the cooker main body 23 of the gas stove 22, and a transmitter is further installed on the range hood 30 for bidirectional communication, and the range hood 30 receives the infrared signal. By sending a half body signal at the time and stopping the transmission of the infrared signal in the gas furnace 22 at the time when the half body signal is received in the gas furnace 22, the number of times of sending the infrared signal can be reduced. The power consumption can be suppressed. This form is particularly useful in the case of the gas furnace 22 using the battery 45 (see FIG. 3) as shown in this embodiment.

(Third operation example)

Subsequently, a third operation example will be described with reference to FIG. 7. 7 is a flowchart showing a third operation example of the gas furnace according to the present embodiment. The third operation example is a modification of the second operation example and differs from the second operation example in the following points.

In the third operation example, after the "mid" operation signal of the ventilation fan 36 is transmitted (step S20) when the heating start is detected (step S20), the operation is again "in" after 3 seconds have elapsed (step S30). The operation of sending a signal (step S40) is repeated until all of the micro switches 27 are turned off (at the time of heating stop detection) (step S50).

For the stop signal, however, the operation of transmitting the stop signal again (step S80) three times after three seconds have elapsed (step S70) since the heating stop detection, as in the second operation example (step S82).

The operation of the range hood 30 is the same as the operation shown in FIG. 5 described in the first operation example.

According to the third operation example, the operation of transmitting the "middle" operation signal again is repeated until all of the micro switches 27 are turned off (at the time of the heating stop detection), so that the operator 60 has a long time from the detection of the start of heating. Even when the position or posture which interrupts the transmission / reception of an infrared ray signal is taken, the infrared ray signal can be reliably transmitted and received between the gas furnace 22 and the range hood 30.

Also in the third embodiment, power consumption can be significantly suppressed by bidirectional communication. In addition, when the power source of the gas furnace 22 is pulled out from the commercial power source, there is no need to replace the batteries, and thus there is little demerit even if a little more power is consumed.

As mentioned above, although the gas stove 22 and the range hood 30 which concern on embodiment of this invention were demonstrated, this invention is not limited to said embodiment at all, Various changes and improvement are based on the knowledge of a person skilled in the art. It can be done in one form.

As described in detail above, according to the heating apparatus according to the present invention, when the heating start or the heating stop is detected (heating start / stop detection), the operator temporarily interrupts the transmission and reception of the infrared signal. Even in the posture, since the infrared signal is re-sent when a predetermined time elapses from the start of heating or stop detection, the infrared signal can be reliably transmitted and received between the heating device and the ventilation device.

In addition, according to the heating apparatus of the present invention, even when the operator temporarily moves to a position where the transmission and reception of infrared signals are interrupted at the time of heating start or heating stop, the time interval from the heating start or heating stop is set. Since the infrared signal is repeatedly transmitted again, the infrared signal can be transmitted and received more reliably between the heating device and the ventilation device.

In addition, according to the ventilator according to the present invention, once the infrared signal is received, the reception of the infrared signal re-sent by the heating apparatus is subsequently invalidated, so that power consumption due to the reception can be reduced. In addition, there is an advantage in that the ventilator that sounds a buzzer when receiving can prevent duplication of the buzzer.
