Operations, such as batching, packing, etc., but the gas in the stove body continues to burn when these operations are carried out, resulting in a waste of gas resources.

In the prior art, in order to solve the above-mentioned problems, a gas valve switch is provided on the stove body to close the gas channel when no combustion is needed, so as to save gas resources. During the process, the operation is frequent, and it is necessary to manually shut down and ignite frequently every time, which makes it very inconvenient to use, not only reduces the efficiency, but also fails to achieve the purpose of saving gas.

Utility model content

The technical problem to be solved by the utility model is to provide a gas stove, which automatically controls the electromagnetic valve and the igniter in real time according to the use status of the gas stove, so as to achieve the purpose of saving gas.

The technical solution adopted by the utility model to solve the technical problem is that a gas stove includes a stove body, a burner and an igniter are arranged in the stove body, and the burner is connected with an air inlet pipe and an air inlet pipe. An electromagnetic valve is arranged on the intake pipe, and an energy-saving detection device connected with the igniter and the electromagnetic valve is also included.

Further, the detection device is a voltage-controlled switch, and the pressure-controlled switch is connected with an igniter and a solenoid valve, or the pressure-controlled switch is composed of a shrapnel and a controller, the shrapnel is connected with the controller, and the shrapnel is set At the stove mouth of the stove body, the controller is connected with the igniter and the electromagnetic valve.

Alternatively, the detection device is an infrared sensing device, and the infrared sensing device includes a transmitting end and a receiving end, which are respectively arranged at the stove mouth of the stove body, and the receiving end is connected with a solenoid valve and an igniter.

Furthermore, the utility model also includes a fan, the fan is connected to the air inlet pipe and the air inlet pipe, the air outlet of the fan is connected to the burner, and the detection device is connected to the power supply of the fan.

The beneficial effect of the utility model is that a detection device is provided at the stove mouth, and by real-time detection of the use state of the frying pan, the automatic control of the opening/closing of the gas channel can be realized, and automatic ignition can be realized when ignition is required without any human operation. Not only easy to use, but also save gas resources. The gas and air are fully mixed through the fan, which improves the combustion efficiency and also saves gas resources.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

As shown in Figure 1, the utility model includes a burner 2 and an igniter 3 arranged in the stove body 1, the burner 2 is connected with an air inlet pipe 4 and an air inlet pipe 5, and the air inlet pipe 5 is provided with an electromagnetic The valve 6 is mainly used to close and open the intake pipe, and a detection device is provided on the cooktop, and the detection device is connected with the igniter 3 and the solenoid valve 6 .

Embodiment 1, as shown in Figure 1 and Figure 2, the detection device is a voltage-controlled switch 7, the voltage-controlled switch 7 includes a controller 71 and a shrapnel 72, the controller 71 is connected to the shrapnel 72, the controller 71 It is also connected with the solenoid valve 6 and the igniter 3, and realizes the control of the solenoid valve 6 and the igniter 3 according to different usage states. The elastic piece 72 is arranged at the stove mouth of the stove body 1 . When the pot is placed on the stove mouth, the shrapnel closes the circuit, and the controller controls the electromagnetic valve to open the intake pipe and the igniter to ignite once. When the pot leaves the stove mouth, the shrapnel disconnects the circuit, and the controller closes the solenoid valve. The controller in this embodiment can be controlled by a single chip microcomputer or other control circuits. No matter which control method can be easily implemented by those skilled in the art, it will not be described in detail.

Embodiment 2, as shown in FIG. 3 , the difference between this embodiment and Embodiment 1 is that the pressure-controlled switch 7 is a closed switch, which is directly connected to the solenoid valve 6 and the igniter 3, which is the same as Embodiment 1. When the pot body is placed on the stove mouth, the switch is closed, the solenoid valve 6 is controlled to open the intake pipe passage, and the igniter 3 is controlled to realize primary ignition simultaneously. When the pot leaves the stove mouth, the switch is turned off, and at the same time, the solenoid valve 6 is closed off the air intake pipe passage, realizing the real-time control of the solenoid valve 6 and the igniter 3, and saving gas resources.

Embodiment 3, as shown in FIG. 4 , the difference between this embodiment and Embodiment 1 is that the detection device is an infrared detection device, and the infrared detection device includes a transmitting end 91 and a receiving end 92, which are respectively arranged at two ends of the stove mouth. On the side, the transmitting end 91 sends an infrared ray to the receiving end 92, as shown by the dotted line in FIG. 4 . When there is no pot in the stove mouth, the receiving end 92 receives the infrared rays, and then closes the solenoid valve; when there is a pot in the stove mouth, the pot body blocks the infrared rays sent by the emitter end 91, and the receiving end 92 cannot receive the infrared rays, and then controls the solenoid valve 3. Open the intake pipe, and simultaneously control the igniter 6 to ignite once. This embodiment also realizes the function of automatically controlling gas combustion, thereby achieving the purpose of saving gas resources.
