[0021]
( Reference Example 1 )
FIG. 3 is a cross-sectional view of Reference Example 1 of the present invention. In FIG. 3, a transmission window 7 and an infrared light emitting element 10 are provided in the main body of the cooking utensil 1, and an exhaust hole 12 is provided in the rear of the top plate 11 located on the upper surface of the cooking utensil 1. Reference numeral 13 denotes a rear wall of the kitchen made of a non-combustible material such as a glossy tile that reflects light such as infrared rays. When the cooking utensil 1 is used, when the operation buttons 3 to 6 are operated, the infrared light emitting element 10 passes through the transmission window 7 and irradiates an infrared signal from the exhaust hole 12 toward the rear wall 13 of the kitchen. The infrared signal reaches the receiving unit 8 of the ventilation fan 2 after being reflected upward.
[0022]
Next, the operation will be described. When the operation buttons 3 to 6 are operated, the infrared light emitting element 10 is configured to irradiate an infrared signal from the exhaust hole 12 toward the rear wall 13 of the kitchen through the transmission window 7. The infrared signal reliably reaches the receiving unit 8 of the upper ventilation fan 2. That is, the color of the position or clothing of a person when that reflects the human body in the cooking appliance 1 front, but that reflection performance turn into varying a material, for reflecting at a predetermined position of the kitchen back wall, a stable reflection performance.
[0023]
(Reference Example 2 )
This reference example relates to control of an interlocking signal when a plurality of stoves and grills of the cooking utensil 1 are used at the same time, and in the case of a plurality of cooking, the infrared communication is not performed between the start of the first cooking and the end of the last cooking. Is. For example, the specification of control when a grill is used while using the left stove will be described. At the time of the first left stove ignition, an infrared signal is transmitted from the cooking utensil 1 to the ventilation fan 2, and the ventilation fan 2 starts operation. After that, when the grill is ignited, the ventilation fan 2 is already in operation, so the infrared signal is not transmitted from the cooking utensil 1, and when extinguishing one of the fire extinguishers, the infrared signal is not transmitted. In addition, the configuration is such that an infrared signal for stopping the ventilation fan 2 is transmitted from the cooking utensil 1 when both the grills are extinguished.
[0024]
Next, the operation will be described. Since it is set as the said specification structure, compared with the case where it transmits for every cooking start and stop at the time of the multiple cooking of the cooking utensil 1, the frequency | count of transmission can reduce and the drive power for transmission can be reduced.
[0025]
(Reference Example 3 )
FIG. 4 is a block diagram of Reference Example 3 of the present invention. In FIG. 4, 14 is a thermocouple provided in the vicinity of the burner as a flame detector for the burner. The start (burner combustion) and the end (burner extinguishing) of cooking are detected by the value of the thermoelectromotive force generated from the thermocouple. An infrared signal is transmitted from the light emitting element 10.
[0026]
Next, the operation will be described. Because it has the above configuration, it detects the end even if the burner extinguishes for some reason, such as spilling during cooking, compared to the detection switch built in the operation button, sends it from the cooking utensil to the ventilation fan, and stops the ventilation fan It is possible to prevent the ventilator from continuing to operate until the cooking utensil is extinguished.
[0027]
(Reference Example 4 )
FIG. 5 is a block diagram of flow rate detection in the gas passage part of Reference Example 4 of the present invention. In FIG. 5, ultrasonic vibrators 16 and 17 are provided in a part of the gas passage portion 15 so as to be opposed to the gas flow direction, and ultrasonic waves are generated between the ultrasonic vibrators 16 and 17 in the gas flow direction and the reverse flow direction. , And the difference between the detection times is measured and calculated to detect the gas flow rate to detect the start and end of cooking.
[0028]
Next, the operation will be described. The above configuration eliminates the need for a detection switch that detects the operation status of each of the multiple operation buttons. By simply detecting the presence or absence of gas flow, an infrared signal is sent from the cooking utensil to the ventilation fan, and the ventilation fan is started and stopped. The cooking start / end detection means can be simplified.
[0029]
(Reference Example 5 )
In this reference example, the operation of the ventilation fan is switched and controlled from the magnitude of the gas flow rate detected in Reference Example 4 , and several types of infrared signals are transmitted from the cooking utensil to the ventilation fan in accordance with the magnitude change in the gas flow rate.
[0030]
Next, the operation will be described. Because of the above-mentioned configuration, for example, the flow rate of high-heat cooking such as stir-fry cooking and small-heat cooking gas cooking such as boiled cooking is detected. In the case of the flow rate, a “weak” operation signal is transmitted from the cooking utensil to the ventilation fan, and the ventilation fan can be ventilated according to the use situation by controlling the operation of the ventilation fan.
[0031]
(Reference Example 6 )
This reference example is configured to notify with a reception sound when receiving a ventilation fan of a signal transmitted from a cooking utensil. Next, the operation will be described. By the said structure, a user can be reliably notified of the interlocking operation state of a cooking appliance and a ventilation fan.
