BACKGROUND OF THE INVENTION
The present invention relates to a cooking device that starts operation of a ventilator in conjunction with the start of operation and ends operation of the ventilator in conjunction with the end of operation.
[0002]
[Prior art]
A technique is known in which the operation of the ventilator is started in conjunction with the start of operation of the heating cooker, and the operation of the ventilator is ended in conjunction with the end of operation of the heating cooker. In this technique, an infrared signal transmitter is provided in the cooking device, and an infrared signal receiver is provided in the ventilator. And from the infrared signal transmission part of the heating cooker, an infrared signal for starting operation of the ventilator is transmitted in conjunction with the start of operation of the heating cooker, and the infrared signal for ending the operation of the ventilation device is interlocked with the end of operation of the cooking device. Send a signal.
The ventilation device is located above the cooking device. If an infrared signal transmission part is provided in the upper surface of a cooking-by-heating machine, an infrared signal can be transmitted toward the infrared signal reception part of a ventilator. However, since pots are placed on the top surface of the cooking device, the optical path for infrared signals may be blocked by the pots. Then, the technique which provides an infrared signal transmission part in the front surface of a heating cooker is proposed. Since the infrared signal is emitted forward from the infrared signal transmitter provided on the front surface of the cooking device, the infrared signal transmitted from the infrared signal transmitter provided on the front surface is above the cooking device. It is not possible to reach the located ventilation device in a straight line. Therefore, an infrared signal is applied to an operator who should be present in front of the cooking device, and the reflected light is received by the infrared signal receiver of the ventilator. Since it is a method of receiving a reflected signal from the operator, it cannot always be received stably. Therefore, in the prior art, infrared signal transmitters are provided at two locations on the left and right ends of the front surface of the cooking device (see Patent Document 1).
According to this method, since the infrared signal transmitters are provided at the two left and right ends, the infrared signal can always reach the ventilator stably regardless of the position of the operator.

[Problems to be solved by the invention]
In order to provide infrared signal transmitters at the left and right ends of the front surface of the cooking device, an electronic device is provided on the back surface of the panel having an operation start / operation end switch and converts the switch operation into an electrical signal. It is necessary to connect between the board on which the circuit board is mounted and the infrared signal transmission unit with a cable. In addition to the substrate for converting the switch operation into an electrical signal, a substrate for an infrared signal transmitter is also required. Since the process of connecting with a cable and the process of incorporating the infrared signal transmission part substrate into the heating cooker require manpower, the manufacturing cost of the heating cooker is increased. In addition, depending on the type of cooking device, there is a type in which it is difficult to provide infrared signal transmitters at the left and right ends of the front surface due to the presence of, for example, a grill.
This invention solves the said subject which exists in the prior art of the system which makes an infrared signal reach | attain a ventilation apparatus stably by providing an infrared signal transmission part in two places of the right-and-left both ends of the front surface of a heating cooker. Make it the purpose.
[0005]
[Means for solving the problems and effects]
The cooking device of the present invention starts the operation of the ventilator in conjunction with the start of operation, and ends the operation of the ventilator in conjunction with the end of operation. This cooking device includes at least a panel, a substrate, and an infrared signal transmitter. The panel is disposed only on one of the left and right sides of the front surface of the cooking device, and has an operation start / operation end switch. The infrared signal transmitter transmits an infrared signal for starting operation of the ventilator in conjunction with the start of operation of the cooking device, and transmits an infrared signal for ending operation of the ventilation device in conjunction with the end of operation of the cooking device. The board is arranged on the back side of the panel, and the electronic device connected to the operation start / operation end switch and all infrared signal transmission units are mounted.
The infrared signal transmitter is above the operation start / operation end switch,
The part that does not face the infrared signal transmitter is impermeable to infrared light,
At least the portion of the panel that faces the infrared signal transmitter is transparent to infrared light.
When the operation start switch is turned ON, the infrared signal is transmitted from the infrared signal transmitter. At this time, since the operator's hand and arm are close to the switch below the infrared signal transmitter, the infrared light emitted from the infrared signal transmitter is surely transmitted to the operator's hand and arm. And is reflected upward by the hand and arm. Therefore, the switch ON operation of the operator is reliably detected in a relatively narrow area on the front surface of the panel. The same applies to the OFF operation of the operation switch.
In addition, said "interlocking with the start of operation of the cooking device" means that the ventilator starts operation at the start of operation of the cooking device or after a predetermined time delay. Similarly, “linked with the end of operation of the heating cooker” means that the ventilation device ends operation at the end of the operation of the heating cooker or after a predetermined time delay. In addition, the “operation start / operation end switch” includes a type in which an operation start switch and an operation end switch exist separately, and a type in which one switch serving as both the operation start switch and the operation end switch exists .
[0006]
In this cooking device, operation start / operation end switches are integrated on a panel brought to one side of the left and right. According to the conventional idea, in order to stably reach the infrared signal to the ventilator, the layout requires an infrared signal transmitter at the front end on the side where the panel is not disposed.
However, when it experimented, even if it did not arrange | position an infrared signal transmission part in the front edge part of the side by which the panel is not arrange | positioned, it was confirmed that an infrared signal can be made to reach a ventilator stably. That is, when the infrared signal transmission unit transmits the operation start infrared signal or the operation end infrared signal, the hand or arm of the person who operates the switch is always present in front of the panel. If the infrared signal transmission unit is provided on the substrate, the transmitted infrared signal is reflected by the operator's hand or arm and stably reaches the ventilator. For this reason, there is no need to provide infrared signal transmitters at the two left and right ends of the front surface of the cooking device, and the infrared signal transmitter is provided on the substrate disposed on the rear surface of the panel brought to the left and right sides. It is possible to start the operation of the ventilator in conjunction with the start of operation of the heating cooker, and to end the operation of the ventilator in conjunction with the end of operation of the heating cooker.
According to this technology, it is not necessary to connect the substrate and the infrared signal transmission unit with a cable, the infrared signal transmission unit substrate is not required, and the infrared signal transmission unit is provided at the left and right ends of the front surface due to the presence of a grill or the like. This makes it possible to cope with difficult types.
[0007]
The entire panel is preferably impermeable to visible light.
An infrared transmissive ink that is opaque to visible light and transmissive to infrared light is known. By printing the panel with the infrared transmissive ink, the infrared transmissive ink is opaque to visible light and not transparent to infrared light. A panel having transparency can be obtained. When a panel that is opaque to visible light is used, the substrate on the back surface of the panel and the infrared signal transmitter (infrared light emitting element or the like) mounted on the substrate can be covered, and the aesthetic appearance is not impaired.
Infrared transmissive ink is expensive, and printing on the entire surface of the panel is expensive. Therefore, if only the portion that becomes the optical path of the infrared signal transmitted from the infrared signal transmitter is printed with infrared transmissive ink, and the remaining portion is printed with normal ink that is opaque to both visible light and infrared, the cost increases. Can be suppressed.
[0008]
It is preferable that the infrared signal transmitters are disposed on both the left and right sides of the substrate.
Even if one of the two infrared signal transmitters is obstructed for some reason by arranging the infrared signal transmitters on the left and right two locations of the substrate, the other infrared signal transmitter An infrared signal can reach the ventilator.
[0009]
DETAILED DESCRIPTION OF THE INVENTION

Various remote switches 26a, 26b, and 26c for manually operating the ventilation device 40 are arranged on the right side of the operation start / operation end switches 22a, 22b, and 22c in the drawing.
[0012]
The panel 20 is provided with a display section for various operating states. These various display units are displayed by turning on or off various light emitting elements arranged on a substrate 30 to be described later. Since the panel 20 does not transmit visible light except for these display portions, the substrate (30: see FIG. 2) disposed behind the panel 20 is not seen through. The panel 20 is provided with infrared transmitting portions 28a and 28b printed with infrared transmitting ink. These infrared transmitting portions 28a and 28b do not transmit visible light but transmit infrared light. These infrared transmitting portions 28a and 28b are provided at two locations on the left and right sides above the operation start / operation end switches 22a, 22b, 22c and 24, respectively.

These indicators are displayed on the display unit of the panel 20 by turning on and off.
[0014]
A pair of transmitting LEDs (infrared light emitting elements) 38 a and 38 b are mounted on both the left and right sides of the upper portion of the substrate 30. These transmission LEDs 38a and 38b are opposed to the infrared transmitting portions 28a and 28b of the panel 20 shown in FIG. Therefore, the infrared signals transmitted from the transmission LEDs 38a and 38b are transmitted toward the front of the heating cooker 10 through the infrared transmission portions 28a and 28b. As described above, since the infrared transmitting portions 28a and 28b do not transmit visible light, the transmitting LEDs 38a and 38b are not seen through the infrared transmitting portions 28a and 28b. FIG. 31 shows a flat cable with a connector for electrical connection with other electrical components.
[0015]

An operation unit 48 provided side by side on the middle right side and a second infrared receiving unit 50 provided on the back side of the hood 42 are provided. Thus, since the ventilation device 40 is provided with the second infrared receiver 50 on the back side of the hood 42 in addition to the first infrared receiver 46, the infrared signal can be received from a wide range.
[0016]
Next, electrical connection between the heating cooker 10 and the ventilator 40 of the present embodiment will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, the on / off state of the various operation start / operation end switches 22 a, 22 b, 22 c, and 24 described above is detected by the switch detection unit 52 inside the cooking device 10. The switch detection unit 52 is connected to a transmission control unit 54, which is connected to the transmission LEDs 38a and 38b. The transmission control unit 54 includes a transmission circuit (not shown) and the like, and according to the ON / OFF state of various operation start / operation end switches detected by the switch detection unit 52, the transmission LED 38a, 38b is transmitted as an infrared signal.
[0017]
As shown in FIG. 4, reception LEDs 56 and 57 (infrared light receiving elements) that receive infrared signals from the transmission LEDs 38 a and 38 b are provided inside the ventilation device 40. In the present embodiment, the first infrared receiving unit 46 shown in FIG. 1 is configured by the receiving LED 56 and a light receiving cover (not shown), and the second infrared receiving unit 50 is configured by the receiving LED 57 and the light receiving cover. These reception LEDs 56 and 57 are connected to a reception control unit 58. The reception control unit 58 outputs a motor control signal in accordance with the infrared signal received by one of the reception LEDs 56 and 57. This motor control signal is transmitted to the motor control unit 60 connected to the reception control unit 58. The motor control unit 60 is connected to a motor 62, and the motor control unit 60 drives and stops the motor 62 in accordance with the received motor control signal. The motor 62 is connected to the ventilation fan 44, and the operation of the ventilation fan 44 is started / stopped according to the driving / stopping of the motor 62, and the like.
[0018]
The heating cooker 10 of this embodiment and the ventilator 40 linked to the heating cooker 10 operate as follows. When the operator operates any of the operation start / operation end switches 22a, 22b, 22c, 24 of the heat source such as the induction heating coil to start the operation, the transmission LEDs 38a, 38b are connected by the electrical connection shown in FIG. An infrared signal for starting the operation of the ventilation device 40 is transmitted from both through the infrared transmission parts 28a and 28b. An infrared signal transmission unit composed of the transmission LEDs 38 a and 38 b and the infrared transmission units 28 a and 28 b is provided on the front surface of the heating cooker 10. Normally, the operator is in front of the heating cooker 10 when operating the operation start / operation end switches 22a, 22b, 22c, 24, and therefore the operation start infrared signal transmitted at the start of operation corresponds to the operator. In particular, in the cooking device 10 of the present embodiment, since the infrared signal transmitter is provided above the operation start / operation end switches 22a, 22b, 22c, 24, the infrared signal transmitted from the infrared signal transmitter is It hits the hand or arm operating the operation start / operation end switch 22a, 22b, 22c, 24. The infrared signal hitting the operator is reflected and irradiated in the direction of the upper ventilation device 40. When an infrared signal is received by either the first infrared receiver 46 provided in the center of the front surface of the ventilation device 40 or the second infrared receiver 50 provided therein, the electrical connection shown in FIG. Thus, the operation of the ventilation fan 44 is started.
On the other hand, when the operator finishes the operation of all the heat sources by operating any one of the operation start / operation end switches 22a, 22b, 22c, and 24 again, the operation of the ventilation device 40 is performed by the same operation. Is terminated. Thus, if at least one heat source is operated, the ventilator 40 operates in conjunction with it, and if all the heat sources have been operated, the ventilator 40 ends operation in conjunction with it.
[0019]
In the conventional cooking device, in order to provide the infrared signal transmitter for interlocking the ventilator at the left and right two locations on the front, a cable is connected between the transmission controller and the two infrared signal transmitters. Was. In the case of a heating cooker in which the grill unit is moved to either the left or right as in this embodiment, an infrared signal transmitter provided on the grill unit side, a cable connected to the infrared signal transmitter, etc. are provided by the grill heater. In some cases, it was overheated.
[0020]
In the cooking device 10 of the present embodiment, the grill unit 18 is disposed on the left side, and the panel 20 is disposed on the right side. The operation start / operation end switches 22a, 22b, 22c, and 24 of each heat source are integrated on this panel. Has been. For this reason, when the operator operates any of the operation start / operation end switches 22a, 22b, 22c, and 24, the transmitted infrared signal is transmitted through the infrared transmission portions 28a and 28b of the panel 20 and the operator's hand. It hits the arm and is easily reflected toward the infrared receivers 46 and 50 of the ventilation device 40. This eliminates the need to provide infrared signal transmitters at the left and right two locations on the front surface of the cooking device, eliminates the need for cables, and allows the transmission LEDs 38a and 38b to be mounted on the substrate 30. Is not overheated by the grill heater.
In addition, since the board | substrate 30 arrange | positioned in parallel with the back surface of this panel 20 will not be seen if it is the panel 20 which does not permeate | transmit visible light like the heating cooker 10 of a present Example. The aesthetic appearance is not impaired, and it is more preferable.
[0021]
Furthermore, the infrared signal can be transmitted over a wider range by arranging the infrared signal transmitting portions in two places as in the cooking device 10 of the present embodiment as compared to the case where the infrared signal is disposed in one place. In this way, an infrared signal can be transmitted by the other infrared signal transmitter even if one of the two infrared signal transmitters is blocked by some cause. Also from this, the operation start or operation end of the heating cooker 10 and the operation start or operation end of the ventilation device 40 can be easily linked more accurately.
[0022]
In addition, like the heating cooker 10 of a present Example, when the transmission part of an infrared signal is provided above each operation start / operation end switch 22a, 22b, 22c, 24, an operator's hand and arm Infrared signals are more likely to hit, and the ventilator 40 can be more easily interlocked.
[0023]
Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.
For example, the ventilator starts operation when a predetermined time elapses after any of the operation start / operation end switches 22a, 22b, 22c, and 24 is operated. In this case, when a predetermined time has elapsed after any of the operation start / operation end switches 22a, 22b, 22c, 24 is operated to start operation, the heating cooker 10 sends an infrared signal for operation start to the ventilator 40. May be transmitted, or the ventilation device 40 may start operation when a predetermined time has elapsed since the ventilation device 40 received the infrared signal for starting operation. Similarly, when a predetermined time has elapsed after all of the operation start / operation end switches 22a, 22b, 22c, and 24 have been operated to end the operation, the heating cooker 10 sends an operation end infrared signal to the ventilator 40. The ventilation device 40 may end the operation when a predetermined time elapses after the ventilation device 40 receives the infrared signal for operation termination.
