Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and more specifically, it relates to a fully premixed multi-cavity driven internal swirl commercial burner. Background Technology

[0002] Existing high-powered gas stoves typically have only one burner with at most two gas nozzles, limiting their heat load capacity. They are insufficient for cooking large quantities of food at once or for quickly serving a full meal, resulting in longer cooking times and low efficiency. Therefore, further improvements to the burner are necessary. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a fully premixed multi-cavity driven internal swirl commercial burner, which aims to solve the technical problems of limited heat load upper limit and low efficiency in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a fully premixed multi-cavity driven internal swirl commercial burner, including an oil tank, a lower burner seat fixed to the upper side of the oil tank, and an upper burner seat fixed to the lower burner seat. The lower burner seat has a lower mounting hole at its center, and the upper burner seat has an upper mounting hole at its center. An internal swirl burner is fixedly installed between the upper and lower mounting holes. At least six atomizer tubes are evenly arranged around the lower mounting hole of the lower burner seat. A furnace chamber air inlet is provided between every two atomizer tubes. A ring of burner ports is provided on the inner conical side of the cap, and the burner ports rotate in the same direction. A central air inlet is provided at the bottom center of the inner rotating burner cap. A central tube passing through the center of the bottom of the oil tank is fixedly provided below the central air inlet of the burner cap. A ring of upper air inlets of the oil tank is provided on the lower side of the central tube. A horizontal fan connecting pipe connected to the central tube is provided on the lower side of the bottom of the oil tank. The top of the central tube is connected to the central air inlet of the burner cap, and the bottom of the central tube is a drain port.

[0006] Furthermore, all the atomizer tubes are tilted in one direction.

[0007] Compared with existing technologies, the advantages of this invention are as follows: It employs up to six or more atomizer tubes, allowing the furnace cavity to be supplied with gas simultaneously by multiple nozzles and atomizers, resulting in a significant increase in heat load. Furthermore, a blower, connected to a horizontal fan pipe, provides secondary gas to the center of the combustion flame from the top of the central tube, while also supplying primary air to the atomized gas within the furnace cavity. This agitates the gas, promotes mixing, stabilizes pressure, propels the gas forward, and improves gas efficiency. The bottom of the central tube is a drain port; when the drain valve is opened, accumulated oil and other conical residues are discharged through the drain port under the force of the blower, ensuring good combustion conditions for the burner through regular draining. The burner nozzle is located on the inner conical surface of the inner rotating flame cap, resulting in an inwardly rotating flame, a more compact flame, rapid flame propagation, no flame overflow, uniform heating, and high cooking efficiency.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] refer to Figure 1 and Figure 2As shown, an embodiment of this utility model is a fully premixed multi-cavity driven internal swirl commercial burner. Importantly, it includes an oil tank 1, a lower burner seat 2 fixed to the upper side of the oil tank 1, and an upper burner seat 3 fixed to the lower burner seat 2. The lower burner seat 2 has a lower mounting hole 4 at its center, and the upper burner seat 3 has an upper mounting hole 5 at its center. An internal swirl burner 6 is fixedly installed between the upper mounting hole 5 and the lower mounting hole 4. At least six atomizer tubes 7 are evenly arranged around the lower mounting hole 4 of the lower burner seat 2, and a furnace chamber air inlet 8 is provided between every two atomizer tubes 7. A ring of burner ports 9 is provided on the inner cone side of the 6, with the burner ports 9 rotating in the same direction. A central air inlet 10 is provided at the bottom center of the inner cone burner 6. A central tube 11 is fixedly provided below the central air inlet 10, passing through the center of the bottom of the oil tank 1. A ring of upper air inlets 12 is provided on the lower side of the burner base 2. A horizontal fan connecting pipe 13 is provided on the lower side of the bottom of the oil tank 1, which is connected to the central tube 11. The top of the central tube 11 is connected to the central air inlet 10 of the burner, and the bottom of the central tube 11 is a drain port 14.

[0014] This design employs up to six or more atomizer tubes 7, with the furnace cavity simultaneously supplied with air by multiple nozzles and atomizers, resulting in a significant increase in heat load. Furthermore, a blower, via a horizontal fan connecting pipe 13, provides secondary air to the center of the combustion flame from the top of the central tube 11, and also provides primary air to the atomized gas within the furnace cavity, agitating the combustion gas, promoting mixing, stabilizing pressure, propelling the gas forward, and improving gas efficiency. The bottom of the central tube 11 is a drain port 14. When the drain valve is opened, accumulated oil and other conical residues are discharged from the drain port 14 under the force of the blower, ensuring good combustion conditions for the burner through regular draining. The burner nozzle 9 is located on the inner conical surface of the inner rotating flame cap 6, resulting in an inwardly rotating flame, a more compact flame, rapid flame propagation, no flame overflow, uniform heating, and high cooking efficiency.

[0015] In a preferred embodiment, all atomizer tubes 7 are tilted in one direction, which controls the direction of airflow. Tilting in one direction can naturally generate swirling flame, reducing the chance of gas and flame escaping.
