Description

Infrared gas stove

technical field

The utility model mainly relates to a gas appliance, in particular to an infrared gas stove.

Background technique

As we all know, thermal load and thermal efficiency are important performance indicators of gas stoves. Thermal efficiency is directly related to the quality of gas or fuel combustion. Since gas needs to be fully mixed with air before it can be completely burned, the quality of gas combustion is related to whether the air is completely Mixing is related. In the prior art, most of the gas stoves use the gas self-pressure injection drainage technology. Since the gas pressure stipulated by the national standard is a fixed value, the amount of injected air is also a fixed value. As a result, the thermal load of the gas hob is limited. At the same time, due to the limitation of air volume, it is difficult to ensure the complete combustion of fuel, which greatly reduces the combustion efficiency of gas. In this case, if sufficient combustion is to be ensured, secondary air must be replenished while burning, which in turn causes the external cold air to cool the combustion flame excessively, reduces the combustion temperature, and also reduces the efficiency of the gas stove.

Utility model content

The technical problem to be solved by the utility model is to provide an infrared gas stove, which can greatly improve the combustion efficiency and heat load of gas.

The technical solution adopted for the technical problem described in the utility model is that the infrared gas stove includes a furnace body, a burner head and a porous infrared ceramic plate or an infrared wire mesh burning plate, the burner head is placed in the furnace body, and the burning plate It is placed on the surface of the furnace head and connected to the outlet of the gas mixing chamber provided in the furnace head. The furnace head is also provided with an air inlet pipe and an air intake pipe. The utility model also includes a forced air supply device. The forced air supply The device is connected with the air inlet pipe. The forced air supply device described in the utility model refers to a device that utilizes external force to drive air other than direct use of gas pressure injection to divert air, such as an electric fan, a pneumatic blower, and the like.

Further, the forced air supply device is also provided with an air volume control device.

Further, the furnace body is provided with a high-temperature combustion chamber, the outlet of the high-temperature combustion chamber is circular, and the combustion plate is a porous infrared ceramic plate or an infrared wire mesh, and is placed at the bottom of the high-temperature combustion chamber.

The beneficial effect of the utility model is that, due to the provision of a separate forced air supply device, the supply air can be freely controlled, and sufficient air volume can ensure a sufficient heat load; at the same time, the mixing degree of air and gas is increased, The combustion efficiency of the gas is improved, and a high-temperature combustion chamber is set on the furnace body. The combination of the combustion chamber and the bottom of the heated object prevents the backflow of external cold air, thereby increasing the combustion temperature, improving the use efficiency, and saving energy. resources, reducing costs.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Detailed ways

Example 1

Referring to Fig. 1, the utility model infrared gas cooker mainly comprises a body of heater 1, a burner head 2 and a porous infrared ceramic plate or an infrared wire mesh burning plate 3, the burner head 2 is placed inside the body of heater 1, and the porous infrared ray ceramic plate Or the infrared wire mesh combustion plate 3 is placed on the surface of the burner 2, and is connected with the gas mixing chamber outlet provided in the burner 2. The burner 2 is also provided with an air inlet pipe 21 and an air inlet pipe 22, which are respectively connected Gas mixing chamber for burner 2. The air inlet pipe 22 is also connected with a forced air supply device 4, and the forced air supply device 4 is provided with an air volume control device 41. The air intake volume can be adjusted by the air volume control device 41, so that the air and gas can be fully obtained. Combustion after mixing to improve the combustion efficiency of gas. As a specific embodiment, an electric fan is used as the forced air supply device 4, and the speed adjustment switch of the electric fan is used as the air volume control device.

A high-temperature combustion chamber 5 is also provided on the burner 2, and the gas outlet of the high-temperature combustion chamber 5 is circular, and a porous infrared ceramic plate or an infrared wire mesh combustion plate 3 is placed at the bottom of the high-temperature combustion chamber 5, so that it can be used as a pot When in contact with the burner 2, the bottom of the pot can be relatively matched with the air outlet of the high-temperature combustion chamber 5, and only the exhaust outlet is left, so that the interior of the high-temperature combustion chamber 5 is formed as a relatively closed space, preventing the backflow of external cold air. It also increases the combustion temperature, which provides a guarantee for complete combustion.

Referring to FIG. 2 , in this embodiment, the high-temperature combustion chamber 5 is higher than the surface of the furnace body 1 . The high temperature combustion chamber 5 is a hollow cylinder made of iron plates.
