Description

Technical Field

[0001] This invention relates to the field of household appliances, and in particular to a burner. Background Technology

[0002] Current gas stove burners generally have an outer burner cap and an inner burner cap. Many inner burner caps have a central through-hole that isolates them from the gas chamber. Air circulation through this central through-hole provides the secondary air supply needed for combustion. However, in actual use, because the inner burner cap is located in the center of the pot bottom, especially for ordinary frying pans, the effective space above the central through-hole is very small, reducing the effectiveness of the secondary air supply. Sometimes, the pot bottom gets too close to the central through-hole, almost blocking it and rendering it useless. Furthermore, during use, food residue often drips from the pot bottom onto the inner burner cap or falls directly into the gas stove through the central through-hole, contaminating the internal structure and making it extremely difficult to clean. Summary of the Invention

[0003] Therefore, it is necessary to provide a burner that addresses issues such as poor air circulation and incomplete combustion in the burner.

[0004] The present invention discloses a burner, comprising: a mounting assembly; a first combustion assembly disposed on the mounting assembly; a second combustion assembly disposed on the mounting assembly, the second combustion assembly having a second through hole and surrounding the first combustion assembly; and an air intake assembly connected to the first combustion assembly and the second combustion assembly, the air intake assembly being located on one side of the mounting assembly, and the first combustion assembly and the second combustion assembly being located on the other side of the mounting assembly.

[0005] This invention discloses a burner, which includes a first combustion component and a second combustion component. The first and second combustion components are mounted on a mounting component, which makes the structure more compact. The second combustion component is arranged around the first combustion component. When the burner is working, the first and second combustion components can work together to provide flames at different positions, thereby meeting different heating needs while avoiding mutual interference with the heating effect and improving combustion efficiency. By connecting the air intake component to the first and second combustion components, sufficient gas supply is ensured. The second combustion component is provided with a second through hole to ensure sufficient air supply, allowing the gas and air to mix more fully, improving combustion efficiency and avoiding the generation of yellow flames.

[0006] In one embodiment, a gap is formed between the first combustion assembly and the mounting assembly. This better ensures airflow, allowing for more complete combustion and improving combustion efficiency.

[0007] In one embodiment, a gap is formed between the second combustion assembly and the mounting assembly. This better ensures airflow, allowing for more complete combustion and improving combustion efficiency.

[0008] In one embodiment, the first combustion assembly is provided with a fourth air passage chamber, and the first combustion assembly is provided with a combustion hole that communicates with the fourth air passage chamber. The communication between the combustion hole and the fourth air passage chamber allows for more thorough mixing of fuel gas and air, improving the mixing effect, increasing combustion efficiency, and preventing the generation of yellow flames.

[0009] In one embodiment, the second combustion assembly is provided with a fifth gas passage chamber, and the second combustion assembly is provided with a combustion channel communicating with the fifth gas passage chamber. The communication between the combustion channel and the fifth gas passage chamber allows for more thorough mixing of fuel gas and air, improving the mixing effect of fuel gas and air, increasing combustion efficiency, and preventing the generation of yellow flames.

[0010] In one embodiment, the first combustion assembly has a first through hole that extends through the first combustion assembly along its height. The first combustion assembly also has a fourth air passage chamber, which is separated from the first through hole. This separation reduces air resistance to the combustion gas, increases the combustion gas flow rate, and improves the prevention of backfire.

[0011] In one embodiment, the first combustion assembly includes a first bottom cover, a first mixing element, and a burner. The first mixing element is disposed on the first bottom cover and has a first air passage chamber.

The first mixing element and the burner are disposed on the first mixing element to achieve a more compact structure. The first air passage chamber is connected to the second air passage chamber via the first air passage hole, and the combustion hole is connected to the second air passage chamber. This allows the combustion gas arriving in the first air passage chamber to be transported to the second air passage chamber. When the combustion gas is burned in the combustion hole of the burner, it creates a siphon effect, drawing air from the surrounding environment to replenish the combustion gas. This allows air to be better introduced into the second and first air passage chambers, thus replenishing the air supply to both chambers.

By connecting the air intake assembly 4 to the first and second combustion assemblies 2 and 3, sufficient gas supply is ensured. The second combustion assembly 3 has a second through hole 34, ensuring sufficient air supply, allowing for more thorough mixing of gas and air, improving combustion efficiency, and preventing yellow flame formation. Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that a gap is formed between the first combustion component 2 and the mounting component 1.

The first ejector tube 41 is used to deliver gas to the first cavity in the first combustion assembly 2, thereby delivering gas to the fourth gas passage chamber. The second ejector tube 42 is used to deliver gas to the fifth gas passage chamber 35 in the second combustion assembly 3, thereby delivering gas to the fifth gas passage chamber 35. The burner assemblies at different positions are independently arranged to provide flames at different positions, thereby meeting different heating requirements.

The damper plate 43 is connected to the first ejector tube 41 and the second ejector tube 42 respectively, and the damper plate 43 covers the air inlets of the first ejector tube 41 and the second ejector tube 42. The damper plate 43 can be used to adjust the gas flow rate of the gas, and deliver it to the corresponding fourth and fifth gas passage chambers 35 through the first ejector tube 41 and the second ejector tube 42 respectively. This allows the gas to have different velocities in the first ejector tube 41 and the second ejector tube 42, which can effectively reduce the gas flow rate at different locations, thereby improving the gas flow effect.

[0089] Optionally, a second support 44 is also included, which is connected to the first ejector tube 41 and the second ejector tube 42 respectively.

[0090] Optionally, it also includes a fire tube connector and a thermocouple, which are respectively mounted on the mounting assembly 1.
