Utility model content

The purpose of this utility model is to provide a fully automatic numerical control energy-saving device for stoves, so as to overcome the disadvantages that the automatic energy-saving devices of common stoves cannot be automatically ignited, cannot reflect the working conditions of the stove in time, waste energy and have low reliability.

The purpose of this utility model is to realize through the following technical solutions:

A fully automatic numerical control energy-saving device for a stove, mainly composed of a signal acquisition switch, a high-voltage ignition transformer, a digital software controller, a pulse solenoid valve, etc., the signal acquisition switch is installed on the stove, the signal acquisition switch and the high-voltage ignition transformer connection, the signal acquisition switch is connected to the digital software controller, and the digital software controller is connected to the pulse solenoid valve; the signal acquisition switch generates a signal when the pot is placed and pressed, and the high-voltage ignition transformer is ignited through the digital software program. Immediately, the pulse electromagnetic valve is opened, and the gas and oil source are directed to achieve the purpose of ignition and combustion of the stove. When the pot leaves the signal acquisition switch, the program is closed, and all combustion phenomena are immediately terminated; the model of the digital software controller is CC1070, and the pulse electromagnetic The model of the valve is RBPC406.

The beneficial effects of the utility model are: the stove automatically ignites and burns when the pot is placed, and automatically extinguishes when the pot is removed, avoiding empty burning, thereby realizing the purpose of energy saving and emission reduction; novel design, high sensitivity, and not easy to damage.

Detailed ways

As shown in Figure 1, the fully automatic numerical control energy-saving device for stoves described in the embodiment of the utility model is mainly composed of a signal acquisition switch 1, a high-voltage ignition transformer 2, a digital software controller (SRD) 3, and a pulse solenoid valve (QD1) 4 and so on. Realized the automatic ignition and combustion of the pulse solenoid valve 4 stove with the placement of the pot, and automatically extinguished with the removal of the pot, avoiding empty burning, thereby achieving the purpose of energy saving and emission reduction.

The signal acquisition switch 1 installed on the stove generates signals with the placement of the pot, the signal acquisition switch 1 is connected with the high-voltage ignition transformer 2, the signal acquisition switch 1 is connected with the digital software controller 3, and the digital software controller 3 is connected with the pulse solenoid valve 4; through the control program of the digital software controller 3, the high-voltage ignition transformer 2 is ignited, and then the pulse solenoid valve 4 is opened to conduct gas and oil sources to achieve the purpose of ignition and combustion of the stove. When the pot leaves the signal acquisition switch 1, the program is closed, and all combustion phenomena are terminated immediately. It avoids the trouble of frequent manual ignition and has a good energy-saving effect.

When the cooking stove equipped with the automatic numerical control energy-saving device described in the utility model is working, turn on the 220V switch of the power supply. Turn on the high-voltage ignition transformer 2, the ignition electrode is ignited, the ignition voltage is 15KV, the pre-ignition time is 0.25s (the safety ignition time is 1s), and then the pulse solenoid valve 4 is opened, the gas and oil sources are turned on, and the combustible substances are ignited to be burned effect. After the pot leaves the signal acquisition switch 1 for 0.5s～1.5s (adjustable), the program is closed, and all combustion phenomena are terminated immediately.

In order to ensure the safe operation of the stove, the high-voltage ignition transformer 2 ignites 0.25s before the gas and oil source pulse solenoid valves are opened, and continues to ignite for 1s after the gas and oil source pulse solenoid valves are opened to ensure the reliability of ignition.

In order to improve the stability of use, the device is potted with epoxy to ensure the use of the device in harsh environments with high temperature and high humidity.

For the safe use of this system, this device uses a high-pressure waterproof socket of 5-10MPa.

The digital control has shrunk, and the system that traditionally uses analog devices has a small size and improved reliability.

The fully automatic numerical control energy-saving device for stoves described in the utility model is installed on any part of the stove, and the signal acquisition switch 1 is installed on the pot ring close to the stove. Through the numerical control software data in the digital software controller 3, by calculating the POT, the high-voltage ignition transformer 2 is ignited, and the pulse solenoid valve 4 is opened after 0.25s to work, that is, the combustible substances in the gas storage and oil tank are opened to achieve the purpose of combustion. When the object to be heated leaves the signal acquisition switch 1, Q1 is closed, and the signal is interrupted. The digital control software in the software controller 3 cuts off the pulse solenoid valve 4 after 0.5s, and the entire combustion process is forced to terminate.

If the system fails, employees can cut off the power supply and continue working without the control of the system.
