CN-114060863-B - Heating cooking system

Abstract

The invention provides a heating cooking system. In a heating cooking system (1), an imaging device (20) can image a stove burner (5) of a heating cooker (10) and a surrounding area thereof. The imaging device (20) detects whether an object has entered the dangerous area during the use of the stove burner (5). When the imaging device (20) determines that an object has entered the dangerous area and notifies the heating cooker (10) of the determination information, the heating cooker (10) executes a fire power reduction control to reduce the fire power of the stove burner (5) to a fire power lower than the current fire power.

Claims (3)

1. 1. A heating and cooking system in which a heating and cooking device is capable of communicating with an image pickup apparatus, the heating and cooking system characterized in that, The image pickup device is arranged above the heating cooker, picks up images of a burner and a peripheral area of the heating cooker, During use of the burner, a region behind the center of the burner when viewed from a standing position of a user is taken as a dangerous area, whether an object invades the dangerous area is detected, When the object is informed of the intrusion into the dangerous area by the image pickup device, the heating cooker performs a fire power reduction control to reduce the fire power of the burner to a fire power lower than the current fire power, The heating cooker is provided with a timing part for timing the period of the fire power reduction control, The timing unit starts timing when the image pickup device detects that an object has entered the dangerous area, and stops the timing when the object is not detected in the dangerous area, After the completion of the fire power reduction control, a fire power increase control is performed to increase the fire power of the burner higher than the current fire power, and the fire power of the burner higher than the current fire power is maintained for at least the period of the fire power reduction control counted by the counting unit.
2. 2. The heating cooking system of claim 1, wherein the heating cooking system comprises, The imaging device includes an analysis unit for analyzing a captured video or image, The analysis unit analyzes the image or the plurality of images in time series to determine an intrusion direction of the object into the dangerous area, The heating cooker executes the fire power reduction control when it is determined that the intrusion direction is a direction from a standing position side of the user to the hazard zone.
3. 3. The heating cooking system of claim 2, wherein the heating cooking system comprises, When it is determined that the direction of invasion is not the direction of invasion from the side of the standing position of the user, the heating cooker executes the fire power reduction control after a predetermined time has elapsed.

Description

Heating cooking system Technical Field The present invention relates to a heating and cooking system including an imaging device and a heating and cooking device. Background Conventionally, a cooking system is known which includes a sensor for detecting a state of a heating cooker such as a stove and which warns when an object such as a human body or clothing enters a detection area of the sensor. For example, the safety device for a stove of patent document 1 described below includes a capacitance measuring unit as a first intrusion measuring unit, and the capacitance measuring unit is mounted at a predetermined position of the stove. The first intrusion measurement unit outputs a detection signal corresponding to whether or not the object intrudes into the first detection area to the control unit. The control unit measures intrusion of the object into the first detection area based on the measurement signal from the first intrusion measurement unit. The safety device for a stove is provided with a distance measuring unit or an imaging unit as a second intrusion measuring unit, and these units are installed at an upper position of the stove so as to face the stove side. The second intrusion measuring unit outputs a signal corresponding to whether or not the object intrudes into the second detection area or image information of the detection area to the control unit. The control unit measures that an object intrudes into the detection area based on measurement signals from the first intrusion measurement unit and the second intrusion measurement unit. The first intrusion measurement unit and the second intrusion measurement unit are relatively small sensors, and therefore can be easily mounted at any position above the oven (patent document 1/paragraph 0014, fig. 3). Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2013-181729 Disclosure of Invention Problems to be solved by the invention However, the range of the second detection area of the safety device for a stove of patent document 1 is wide, and the second intrusion measurement unit is not the case of detecting only a specific burner. In addition, since the apparatus combines the first intrusion measurement unit and the second intrusion measurement unit and detects the intrusion, the apparatus does not detect the intrusion of the object with high accuracy only by the imaging unit. The present invention has been made in view of the above circumstances, and an object thereof is to provide a heating and cooking system capable of detecting an object that has entered a specific area with a simple structure and high accuracy. Means for solving the problems In order to achieve the above object, the present invention provides a heating and cooking system capable of communicating between a heating and cooking device and an imaging device, the heating and cooking system characterized in that, The image pickup device is arranged above the heating cooker, picks up images of a burner and a peripheral area of the heating cooker, takes an area behind the center of the burner when being observed from a standing position of a user as a dangerous area during the use of the burner, detects whether an object invades the dangerous area, When the image pickup device informs that the object enters the dangerous area, the heating cooker executes the fire power reducing control to reduce the fire power of the burner to be lower than the current fire power. In the heating cooking system of the present invention, the imaging device is provided at a position above the heating cooker, and therefore the imaging device can image the burner of the heating cooker and the peripheral region thereof. The image pickup device detects intrusion of an object into the dangerous area during use of the burner and notifies the cooking device. When the imaging device detects that an object (for example, a person's hand or clothes) has entered the dangerous area, the heating cooker performs a fire-reducing control. Thus, the system can detect an object intruding into the dangerous area with high accuracy with a simple configuration, thereby ensuring safety. In the cooking system according to the present invention, it is preferable that the imaging device includes an analysis unit that analyzes a captured image or image, the analysis unit analyzes the image or a plurality of images in time series to determine an intrusion direction of the object into the dangerous area, and the heating cooker executes the fire reduction control when it is determined that the intrusion direction is a direction from a standing position side of the user into the dangerous area. An analysis unit of the imaging device analyzes the video image and the plurality of images in time series order to determine an intrusion direction of the object into the dangerous area. When the heating cooker is informed that the invasion direction is the direction from the standing position
