Fig. 1 is an illustration of a three-dimensional structure of a combustion range 100 according to an embodiment of the present invention. Fig. 2 is an exemplary diagram of a back structure of the combustion hob 100 in fig. 1. Fig. 3 is a schematic electrical circuit diagram of the combustion hob 100 in fig. 1.

As shown in fig. 1 to 3, the combustion cooker 100 includes a cooker body 10, a burner 20, a gas pipe 21, a firing pin 31, a firing switch 32, a control module 70, a human body sensor 71, and a control valve 72.

The cooktop body 10 may include a panel 11 and a case 12 provided below the panel 11. A vent hole 13 and a control box 14 are provided in the housing 12. In other embodiments, the cooker body 10 may be set to other shapes, increasing or decreasing some structures, however, these changes do not affect the implementation of the present invention, all belong to the protection scope of the present invention.

The burner 20 is disposed on the panel 10 of the cooker body 10, and has an air outlet for outputting combustible gas and an air inlet for inputting combustible gas. The gas pipeline 21 is at least partially arranged in the shell 12, and the gas pipeline 21 is communicated with the gas inlet of the burner so as to deliver combustible gas to the burner 20. In one embodiment, the air inlet of the burner 20 and the gas duct 21 may be of an integral design or of a split design.

The firing pin 31 is disposed adjacent to the outlet of the burner 20. The sparks generated by the firing pins 31 can ignite the combustible gas output from the gas outlet of the burner 20. The ignition switch 32 is electrically connected to the ignition needle 31. When the ignition switch 32 is actuated, the ignition needle 31 can ignite a spark. The combustion hob 100 further comprises a battery to supply power to the ignition needle 31, which is not shown in the figures due to its low relevance to the working principle of the present invention.

The control module 70 may be disposed in the control box 14, and of course, may be disposed in other suitable locations, the control module 70 may include an integrated circuit, and may also include other forms of control units, and the control module 70 may include one component, and may also include multiple components disposed in different locations. The human body sensor 71 is used for generating and outputting a human body sensing signal representing whether a human body exists or not, and is electrically connected with the control module 70. In one example, as shown in fig. 1, the motion sensor 71 is provided on a side end surface of the panel 11, but may be provided at another suitable position. The human body sensor 71 may be a contactless proximity sensor, an infrared sensor, a thermal infrared human body sensor, an ultrasonic sensor, or other existing detection sensors capable of detecting a moving object. In one example, the human body sensor 71 may output a human body sensing signal representing a human body whenever an object or a motion of the object is detected. The specific human body sensing principle is not the focus of the present invention and therefore is not described in detail herein. The control valve 72 is disposed on the gas pipeline 21, and can be electrically connected to the control module 70. The control valve 72 is configured to be capable of being turned off or on to disable or enable the gas conduit 21 to deliver combustible gas to the burner 20. In one example, the control valve 72 may be a solenoid valve.

If the human body sensor 71 does not detect a human body continuously for a first predetermined time period T1 while the burner 20 is burning, the control module 70 will cause the control valve 72 to close to prohibit the gas conduit 21 from delivering combustible gas to the burner 20. The control valve 72 remains open until the control valve 72 is closed. Thus, when people forget due to negligence and cause the burner 20 to heat the pot for a long time, the human body sensor 71 continuously does not detect the human body in the T1, so that the gas pipeline 21 is prohibited to convey combustible gas to the burner 20, and the problems that the food is burnt and fire disasters are possibly caused due to the fact that the food is heated for a long time without being attended on site are avoided.

In one embodiment, the control module 70 has a timer therein, and when the burner 20 is burning, the timer counts to obtain a timing value, and if the human body sensor 71 detects a human body, the timer is reset to reset and count again, and the timing value is used to determine the duration of time that the human body sensor 71 does not detect the human body. After the burner 20 is extinguished (changed from a burning state to an unburned state), the timer is reset to an initial value.

As shown in fig. 3, the combustion hob 100 further comprises an alarm device 73. The alarm device 73 is electrically connected to the control module 70, and can generate and output an alarm signal. When the burner 20 is burning, if the human body sensor 71 does not detect the human body continuously within a second predetermined time period T2 which is less than the first predetermined time period T1, the control module 70 controls the alarm device 73 to alarm. The alarm device 73 may be an audible alarm, which may sound a drip, a drip alarm, or other forms of alarm. In one example, the second predetermined time period T2 may include two different time period values, which are respectively denoted as T21 and T22, and when the timing value of the timer is greater than T21, the alarm device 73 is used to alarm for the first time, when the timing value of the timer is greater than T22, the alarm device 73 is used to alarm for the second time, and when the timing value of the timer is greater than T1, the control valve 72 is directly controlled to be closed. Of course, each preset time length can be adjusted and set according to needs.

As shown in fig. 1 and 2, in one embodiment, the combustion hob 100 further comprises: a knob 50 disposed on the upper side of the panel 11, and a valve assembly 40 disposed on the lower side of the panel 11 opposite to the knob 50. The control valve 72 is included in the valve assembly 40. The knob 50 can be rotated from the initial position, the valve assembly 40 is arranged on the gas pipeline 21, the knob 50 and the valve assembly 40 are matched to adjust the quantity of the combustible gas conveyed to the burner 20 through the gas pipeline 21, and when the knob 50 is located at the initial position, the valve assembly 40 completely cuts off the gas pipeline 21. The ignition switch 32 is disposed on the valve assembly 40, and the knob 50 can be pressed to drive the ignition switch 32, so as to trigger the ignition needle 31 to spark. In another embodiment, the amount of the combustible gas delivered to the burner 20 through the gas pipeline 21 may be adjusted without using the knob 50 and the valve assembly 40, or the amount of the gas passing through may be controlled directly by using a solenoid valve capable of being controlled step by step, or other manners may be used.

As shown in fig. 3, the combustion hob 100 further comprises a reset sensor 74. The reset sensor 74 is electrically connected to the control module 70 and configured to generate and output a reset sensing signal indicating whether the reset is performed. In one embodiment, the reset sensor 74 is disposed on the valve assembly 40, and when the knob 50 is in the initial position, the reset sensor 74 can be triggered to cause the reset sensor 74 to send a reset sensing signal indicative of a reset. As the knob 50 is rotated away from the initial position, the reset sensor 74 emits a reset sensing signal indicative of non-reset. In one embodiment, after the third predetermined time period T3 when the control module 70 receives the reset sensing signal being reset, the T3 may be, for example, 5 minutes, so that the circuitry in the combustion hob 100 is put into a sleep mode, which may reduce power consumption.

As shown in fig. 1 and 3, the combustion hob 100 further comprises a combustion sensor 75. Combustion sensor 75 is close to the gas outlet setting of combustor 20 can export the burning inductive signal whether the sign burns, combustion sensor 75 with control module electric connection. The burner 20 is considered to be burning when the control module 70 receives a combustion sensing signal indicative of combustion, otherwise, the burner 20 is considered to be unburned. In one embodiment, the combustion sensor 75 is a thermocouple, and the combustion sensor 75 may be inserted deep into a flame to detect when the burner 20 is burning.

In one embodiment, depressing the knob 50 mechanically actuates the control valve 72 to open to allow the gas conduit to deliver combustible gas to the burner 20 and to cause the control valve 72 to remain open when the burner 20 is considered to be burning. For safety reasons, the control module may receive a combustion sensing signal indicating that combustion has changed from indicating combustion to indicating non-combustion, which may be due to a flame being extinguished by accident (e.g., wind, liquid spill) during combustion, or for other reasons, such as manual shut-off of the burner, and the control module 70 may cause the control valve 72 to shut off to prohibit the gas conduit from delivering combustible gas to the burner 20, thereby eliminating a safety hazard.

It can be seen that, the utility model discloses an integrated human body sensor in burning cooking utensils 100 during the combustor burning, if in first predetermined duration, human body sensor lasts and has not detected the human body, control module will make the control valve turn-offs in order forbidding the gas pipeline gives the combustor carries combustible gas, has avoided like this because careless forgetting, causes food overlength time heating, arouses food to burn and probably causes the problem of conflagration.
