In the novel energy-saving cooker with automatic ignition and alarm, a temperature control switch is arranged on the outer surface of the mirror-faced aluminum support.

The new energy-saving cooker with automatic ignition and alarm is provided with a 220v alarm and a 6v alarm on the load-bearing frame.

In the novel energy-saving cooker with automatic ignition and alarm, four cooker feet are fixed on the lower part of the outer shell of the cooker.

In the new energy-saving cooker with automatic ignition and alarm, the inner surface of the mirror-faced aluminum support is screwed and fixed with an anti-leakage copper cover, and the anti-leakage copper cover is provided with a ceramic circle inner concave resistance fixed with a resistance wire. body.

The beneficial effects of the utility model are:

The design feature of the utility model is mainly the cone structure design of the double-layer mirror aluminum support and the hollow stainless steel support on the cooktop. The conical surface of the pot is made of mirror aluminum material, which reflects infrared rays to the bottom of the pot and improves the utilization of waste heat. The inner and outer double-layer structure allows air and flue gas to flow back, increases air preheating, and reduces the amount of nitrogen oxides produced.

Fig. 2 is a partial cross-sectional structure diagram of the bottom of the mirror aluminum support and the hollow stainless steel support in Fig. 1 .

Detailed ways:

The following descriptions are only preferred embodiments of the present utility model, and do not therefore limit the protection scope of the present utility model.

As shown in accompanying drawings 1-2: a new type of energy-saving stove with automatic ignition alarm, including a cooker shell 1, four support columns 3 are screwed and fixed on the load-bearing frame 2 inside the cooker shell 1, and four support columns 3 are fixed on the four supports The column 3 is clamped with an inverted conical hollow stainless steel support 4 and an inverted truncated mirror aluminum support 5. The mirror aluminum support 5 is located inside the hollow stainless steel support 4 and has a height difference with it, that is, the The upper top surface of the hollow stainless steel support 4 is higher than the upper top surface of the mirror aluminum support 5, and there is a certain distance between the two. On the inner surface of the mirror aluminum support 5, a disc-shaped copper tube 6 is welded. The bowl-shaped sealing portion 401 of the hollow stainless steel support 4 is provided with a direct-injection gas burner 10 .

A temperature control switch 11 is provided on the outer surface of the mirror aluminum support 5 .

A 220v alarm 12 and a 6v alarm 13 are arranged on the bearing frame 2 .

Four stove feet 14 are fixed on the lower part of the stove shell 1 .

The inner surface of the mirror-faced aluminum support 5 is screwed and fixed with an anti-leakage copper cover 7 , and a ceramic circular concave resistance fixing body 9 with a resistance wire 8 is arranged in the anti-leakage copper cover 7 .

working principle:

Connect the energy-saving cooker to the power supply, open the gas valve, turn on the gas assembly switch 15 on the cooktop shell 1, ignite, the flame generates infrared rays to the bottom of the pot, the mirror aluminum support 5 begins to absorb part of the heat energy, and continues to increase the burning intensity of the flame. Due to the inverted cone structure of the hollow stainless steel support 4 on the cooktop, the whole cooker body forms a semi-closed structure, and the burning flame does not directly exchange heat with the outside air, but the direct injection gas burner 10 along the outer gap Entering the secondary air, the point-to-face heat transfer method makes the combustion flame close to the bottom of the pot to improve thermal efficiency, greatly shorten the time and reduce energy consumption.

According to the principles of radiation heat transfer and convective heat transfer, the utility model adopts semi-closed turbulent diffusion combustion so that the burning flame does not directly exchange heat with the outside air, and adopts direct injection combustion to mix 70% air with gas pressure, and the point-to-face heat transfer flame is tight. Stick it on the bottom of the pot to improve thermal efficiency. Since the aluminum surface of the mirror aluminum support 5 absorbs part of the heat energy, the converted air is preheated at 120-150°C, thereby increasing the physical enthalpy and improving the utilization rate of heat energy. The upper part of the side of the injection burner 10 is about 0.8-1.0cm away from the lower part of the burning flame of the direct injection burner 10. The wall thickness of the disc-shaped copper tube 6 is 1mm and the inner diameter is 4.0mm. (The hydraulic test pressure is 4.9mpa and the duration is 10-15s) , with a total length of 1.5 meters. The resistance wire 8 is connected to the temperature control switch 11 and the 220v alarm 12 via cables, and is connected to the gas assembly switch 15. After the gas is ignited, the temperature rises. When the temperature reaches 190°C (±5°C), the temperature control switch 11 automatically cuts off the power supply , this process takes about 30 seconds. When the temperature in contact with the temperature control switch 11 is lower than 190°C (±5°C), the power supply will be turned on to heat the resistance wire 8 for about 3 seconds, so that the direct injection burner 10 will be re-ignited, and at the same time The 6v alarm 13 can send an audible alarm, and the 220v alarm 12 can issue an audible alarm if the flame is accidentally turned off in the absence of alternating current.
