Description

Commercial high-efficiency energy-saving cooker

technical field

The utility model relates to a cooking range head, in particular to the manufacturing field of a commercial range head which adopts an infrared ceramic burning plate, is energy-saving and environment-friendly.

Background technique

The existing household gas cooker for kitchen is mainly composed of a burner and a hob. The burner is usually made of cast iron. The gas and air are introduced into the annular chamber through the gas inlet pipe and the air inlet pipe to mix, and then ignited by the igniter for combustion. , the combustion gas is sprayed out through the holes on the annular chamber to complete the heating operation. It has the following disadvantages and deficiencies: first, the thermal energy utilization rate of the gas is low; second, the firepower distribution is uneven, and it is only concentrated at the gas injection hole of the annular chamber.

When the existing commercial stoves are in use, blowers are usually used to blow air to assist combustion, which has disadvantages such as extra power consumption and high noise, and also has the problem of low utilization rate of gas heat energy.

Utility model content

The purpose of the utility model is to provide a commercial high-efficiency energy-saving cooker with good combustion effect and high heat energy utilization rate.

The purpose of this new model is achieved in this way: a commercial high-efficiency energy-saving stove head, the inner and outer cylinders arranged concentrically and the infrared ceramic combustion plates arranged on the top openings of the inner and outer cylinders form the inner and outer combustion chambers. The horn-shaped tubes are respectively arranged on the inner and outer combustion chambers along their tangential direction and communicated with them, and the flow direction of the air intake of the two horn-shaped tubes in the inner and outer combustion chambers is opposite; the radiation net is arranged above the infrared ceramic combustion plate; Gas nozzles are arranged on the air inlets at the outer ends of the two trumpet-shaped tubes.

The beneficial effects of the utility model are:

1. Energy saving, gas saving and environmental protection

The novel technical point, one, adopts ceramic burning infrared ray plate (being infrared ray burning plate), and its shape is inverted cone shape, has more than 10,000 fire holes on it. When the flame is burning, the flame is converted into infrared rays to speed up the heating process of the object. Due to the transmission of infrared radiation, the performance of the gas stove is greatly improved; secondly, the inner cavity of the stove head is divided into two concentric chambers, and each chamber is introduced with gas and air by a trumpet-shaped drainage tube. This special internal structure using aerodynamic technology promotes the turbine-type rotation of the gas after entering the combustion chamber of the stove, so that the gas can be more fully pre-mixed, and the mixed gas is evenly distributed to more than 10,000 fire holes, and the gas is guided through the fire holes. The flow spiral overflows, and continuously delivers the mixed gas required for combustion to each fire hole, and enhances the adhesion of the mixed gas to the fire hole after the spiral overflows the fire hole, so that the gas is adsorbed on the surface of the combustion plate for full combustion. Effectively suppress the precipitation of harmful gases such as CO, CH, NO×, and the powerful heat flow converts heat energy into flameless infrared radiation transfer, making the most effective and full use of the heat flow generated by gas combustion, greatly reducing the physical The loss of heat flow saves gas up to 50%.

2. It is specially designed for commercial use, and no longer uses a blower to blow air in for combustion. It has the functions of stable combustion, no noise, and energy saving.

3. The stove head is made of steel plate covered with a layer of enamel material. The stove has a service life of up to 10 years and is durable.

4. The infrared ceramic combustion plate (with numerous micropores on it) adopts a flat design and fits with the radiation net. Compared with the concave infrared combustion plate, the combustion chamber is larger, and the number of cycles of the rotating airflow in the combustion chamber More, the mixing of gas and air is more complete, which is conducive to the combustion in an ideal state.
