Description

Gas stove energy saving control system

technical field

The utility model mainly relates to an energy-saving control system for a gas stove.

Background technique

During the whole cooking process, in addition to placing the frying pan on the stove to heat and stir fry, the chef also frequently leaves the stove for other processes, such as ingredients, loading, etc., and the fire is not needed when performing these processes. The occupied time accounts for more than 30% of the entire cooking time. Since the chef moves frequently during the cooking process, it is impossible to manually turn off and ignite the fire frequently, and almost all frying stoves on the market have not been able to adjust according to the cooking needs. The function of automatically controlling the fire, so that the frying stove continues to burn during a large amount of time when the fire is not needed, resulting in a lot of waste of resources.

In order to solve the above problems, at present there is a technology of using an infrared switch to detect the position of the frying pan, and to automatically control the fire according to the position of the detection frying pan. When used in the harsh environment of oil fume, the infrared switch is easily affected by the ambient temperature and dust. The diffuse reflective infrared switch cannot accurately determine the position of the frying pan when detecting a black-colored frying pan, and the through-beam and feedback reflective infrared switches are inconvenient to install on a high-temperature, oily and fume frying stove. Technology is difficult to promote in actual use.

Utility model content

The technical problem to be solved by the utility model is to provide an energy-saving control system for a gas stove so that it can effectively and automatically control the fire and achieve the purpose of saving resources.

The technical solution adopted for the technical problem described in the utility model is that the gas stove energy-saving control system includes a gas stove, an igniter, and a solenoid valve for controlling the on and off of the fuel pipe. Connected ultrasonic detection device.

Detailed ways

As shown in Fig. 1 and Fig. 2, the gas stove energy-saving control system of the utility model includes a gas stove 1, an igniter 3 and an electromagnetic valve 4 for controlling the fuel pipe 6 to be on and off, and also includes the igniter 3, the electromagnetic valve 4 are electrically connected to the ultrasonic detection device 2 . The ultrasonic detection device 2 is placed on the outside of the stove mouth, so that the entire top of the stove mouth is completely covered within the detection and control range of the ultrasonic signal sent by the ultrasonic detection device 2 . The ultrasonic detection device 2 includes a controller 21, an ultrasonic generating circuit 22, a signal receiving circuit 23 and a power supply; the controller 21 controls the ultrasonic generating circuit 22 to transmit signals; the signal receiving circuit 23 transmits a feedback signal to the controller 21 ; The controller 21 is electrically connected with the solenoid valve 4 and the igniter 3 .

The solenoid valve 4 is connected to the fuel pipe 6 , the fuel pipe 6 communicates with the furnace core 7 in the gas stove 1 , and the ignition needle of the igniter 3 is arranged in the furnace core 7 .

In the utility model, the fuel pipe 6 is also connected with a main valve 5 for controlling fuel on and off, and the main valve 5 is also provided with a proximity switch 53 controlled by it, and the proximity switch 53 is connected with the ultrasonic detection device 2 power connection. Its working principle is: as shown in Figure 4, when the valve of main valve 5 was closed, one end of its handle 51 was then close to the detection range of probe 52 of proximity switch 53, and proximity switch 53 was powered off; During the valve, one end of the handle 51 then exceeds the detection range of the probe 52, and the proximity switch 53 is energized. Thus, the purpose of the valve opening the electricity and the valve closing the electricity breaking is realized.

The working principle of the utility model adopting the above structure is as follows: as shown in Figure 3, when the gas stove needs to be fried, put the corresponding pot into the stove mouth of the gas stove, first open the main valve 5, and make the proximity switch 53 energized , and then the ultrasonic detection device 2 is energized to work. At this time, the controller 21 inside the ultrasonic detection device 2 works, and then controls the ultrasonic generation circuit 22 to transmit ultrasonic signals, and the signal receiving circuit 23 receives the returned ultrasonic signals, and the controller 21 will transmit the signal The time used between receiving the signal is compared with the longest return time set inside the controller 21. The longest return time refers to sending a signal from the ultrasonic generating circuit to the position above the edge of the other side of the gas stove, and returning The time it takes to reach the signal receiving circuit. As shown by the dotted line in Figure 1.

When the time spent from transmitting the ultrasonic signal to receiving the returned ultrasonic signal is less than the longest return time, it indicates that there is a frying pan above the gas range, and frying is required, and then the controller 21 energizes the igniter 3 and ventilates the electromagnetic valve 4. If the time taken from transmitting the ultrasonic signal to receiving the returned signal is greater than or equal to the longest return time, it indicates that there is no wok above the gas stove or the wok has left the gas stove. Then do not need to ignite, just make igniter 3 de-energize and electromagnetic valve 4 cut-off gas, stop working.

The utility model includes but is not limited to the scope of protection of the above embodiments, any inventions and creations based on or utilizing the above ideas of energy-saving control systems for gas stoves. All belong to the protection scope of the present utility model.
