Description

  The present invention relates to a heating cooker that wirelessly performs a signal for operating a ventilator in conjunction with heating on / off.

  Conventionally, with regard to cooking devices that heat pans and other ventilation devices that are linked to heating on / off, a wired method is used to send a signal from the heating cooker to the ventilation device, and infrared or radio waves are used. In addition, there is known a system that wirelessly transmits a signal from a heating cooker to a ventilator (see, for example, Patent Document 1). In particular, in recent years, wireless systems that do not require wired work for interlocking have been adopted. Hereinafter, the operation of the heating cooker for interlocking by a wireless method will be described.

  FIG. 5 is a block diagram showing the configuration of a conventional cooking device and a ventilator that is linked to on / off of the cooking device. In FIG. 5, reference numeral 1 denotes a single-phase three-wire commercial power source of a general household, 2 denotes a heating cooker, 3 denotes a range hood which is a ventilation device for ventilating a kitchen or the like in which the heating cooker 2 is installed. Further, 4 is a heating means for heating a pan or the like in the heating cooker 2, 5 is a heating control means for controlling the heating means 4, 6 is an operating means for setting heating on / off or heating power of the heating means 4, and 7 is an operation. This is a wireless transmission means for transmitting a signal by infrared rays when heating is turned on / off by means 6.

  8 is a wireless receiving means for receiving a wireless signal from the heating cooker 2 in the range hood 3, 9 is a ventilation fan for ventilating, and 10 is a ventilation fan control means for controlling the ventilation fan.

  About the cooking device 2 and the range hood 3 comprised as mentioned above, the interlocking | linkage operation | movement is demonstrated using the timing chart of FIG.

  FIG. 6 (6-a) shows the heating state of the heating means 4. Similarly, (6-d) represents the operation of the range hood 3. (6-b) is an ON signal from the wireless transmission means 7, and (6-c) is an OFF signal from the wireless transmission means 7. Here, both the ON and OFF signals from the wireless transmission means 7 are high and low signals. However, in actuality, transmission is performed using different encoded signals. At the same time when the heating means 4 is turned on, the wireless transmission means 7 outputs an ON signal once. Similarly, when the heating means 4 is turned OFF, an OFF signal is output once. The wireless receiving means 8 receives these signals from the wireless transmitting means 7, and the ventilation fan 9 of the range hood 3 performs an on / off operation.

However, in the conventional cooking device, transmission of the on / off signal by the wireless transmission means only transmits one encoded code signal, and only the range hood corresponding to the code signal can be linked. In other words, if the on / off signals are different for the range hoods of different manufacturers, the code signal to be transmitted for the same interlocking operation must be changed. Or having the code signal changed in advance must be prepared, which causes management and cost increase for distinguishing them.

In order to solve the conventional problem, the heating cooker according to the present invention includes a heating unit, an operation unit for turning on and off the heating unit, and the heating unit being turned on and off by the operation unit. Wireless transmission means for wirelessly transmitting an on / off signal to interlock the ventilation device in conjunction with the state, and the wireless transmission means uses at least two different code signals with the same control command. transmits sequentially using, among the different code signals in the control command of the same meaning, it is an cooker for transmitting sequentially shorter code signal of the code length.

(Embodiment 1)
The first embodiment of the present invention will be described below. FIG. 1 is a configuration block diagram of a heating cooker and a ventilator that is linked to the on / off of the cooking device.

  In FIG. 1, 1 is a commercial power source for single-phase three-wires in a general household, 2 is a heating cooker, and 3 is a range hood that is a ventilation device for ventilating a kitchen or the like in which the heating cooker 2 is installed. Further, 4 is a heating means for heating a pan or the like in the heating cooker 2, 5 is a heating control means for controlling the heating means 4, 6 is an operating means for setting heating on / off or heating power of the heating means 4, and 7 is an operation. This is a wireless transmission means for transmitting a signal by infrared rays when heating is turned on / off by means 6.

  8 is a wireless receiving means for receiving a wireless signal from the heating cooker 2 in the range hood 3, 9 is a ventilation fan for ventilating, and 10 is a ventilation fan control means for controlling the ventilation fan.

  Wireless transmission means 7 in the case of three manufacturers having different range hoods 3 interlocked with the heating cooker 2 in the configuration as described above and having different control command code signals for linking each company's range hoods on and off. The interlocking timing between the interlocking signal transmitted by each company and the range hood of each company will be described with reference to the timing chart of FIG.

  When heating by the cooking device 2 is started by the operation means 6, the wireless transmission means 7 transmits a code "a" which is a code corresponding to the control command signal for turning on the range hood of company A. Next, the code “b”, which is a code corresponding to the control command signal for turning on the range hood of the B company, and finally the code “c”, which is a code corresponding to the control command signal for turning on the range hood of the C company. Send. In this case, if the transmission interval of each signal is set to a time longer than the trailer code indicating the end of each code, the wireless reception means 8 can correctly receive a valid signal. As a result, it is not necessary to make a product corresponding to each range hood on the cooking device side, and it is not necessary to create and manage a plurality of boards provided with the wireless transmission means 7 and to share them.

  Further, when the code length of each code is a <b <c in this embodiment, the transmission order is transmitted in order from the signal with the short code length until the manufacturer linked to the second code is linked. Can be made earlier, and the uncomfortable feeling of the interlocking operation can be alleviated as much as possible.

  In addition, as shown in FIG. 3, when the operation means 6 of the heating cooker 2 is turned on and off for a short time, the cooking is first performed while the wireless transmission means 7 sequentially transmits the interlock on signal. When the heating of the vessel 2 is stopped (finished), the transmission of the ON signal is stopped at the timing when the heating is stopped, and the OFF signal is transmitted. As a result, in the case of the range hood of Company A that starts ventilation operation with the code “a” that has already been correctly transmitted, “d” that is an off signal is received again, and ventilation is performed when the heating cooker 2 stops heating. The operation can be turned off.

  In addition, since the wireless transmission means 7 stops transmitting the on signal before transmitting the code “b”, the range hood of company B does not receive the correct signal and the operation remains in the off state. Yes, and then receives the off signal “e”, but since it is an off signal in the off state, the range hood can be kept off when heating is off. Thereby, the user can eliminate a sense of incongruity in the operation of the cooking device and the range hood. Furthermore, it is possible to make the wireless transmission means 7 relatively inexpensive by configuring it with infrared rays.

  The infrared carrier frequency is set to 36.7 kHz, which is a format format of the home electric appliances association (hereinafter referred to as “household cooperative”), which is often used in general remote control devices, so that a general-purpose microcomputer or IC is used. Can be made relatively inexpensive.

  In addition, there may be a plurality of carrier frequencies for a plurality of signals transmitted by the wireless transmission means 7. For example, it is assumed that the codes “a” and “c” use 36.7 kHz for the carrier frequency, and the code “b” uses 38.0 kHz. In general, a light receiving element used for a wireless receiving means receives signals for each carrier frequency through a bandpass filter having the characteristics shown in FIG. 4, and the interlocking operation of the heating cooker 2 and the range hood 3 in the installed state. For example, reception is possible even if the frequency is 37.5 kHz. Thus, the program can be simplified by using one type of carrier frequency.

  As described above, in the heating cooker according to the present invention, the wireless transmission means transmits at least two different code signals in order with the same control command, in conjunction with the ventilation devices of a plurality of manufacturers, and those When the interlocking signal of the ventilator is different, the board with the wireless operating means can be shared, so that the cooking device performs wirelessly a signal for operating the ventilator in conjunction with heating on / off It can be applied to such uses.
