Description

Technical Field

[0001] This utility model relates to the field of commercial stove burner technology, specifically a premixed commercial stove burner with drainage capability. Background Technology

[0002] The burner of a natural gas stove mainly consists of two parts: the burner head and the premixer. The premixer plays a decisive role in the combustion condition of the gas stove, as it determines whether the gas is completely burned. The premixer mixes the gas and air in advance before sending it to the burner head for combustion, resulting in very low carbon monoxide levels in the exhaust gas after complete combustion.

[0003] Optimizing the premixer enables more complete combustion of natural gas and allows for control of the air-to-fuel ratio, preventing excessive heat loss and improving thermal conversion efficiency. Furthermore, commercial stove burners frequently experience water accumulation during use due to cleaning, pot cracking, and other factors. If this water is not drained promptly, it can damage the ignition device and cause malfunctions. Therefore, a water drainage function is essential to reduce the incidence of such failures. Consequently, those skilled in the art have provided a premixed commercial stove burner with drainage capability to address the problems mentioned in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a premixed commercial stove burner with drainage capability, which solves the problem that water accumulation in commercial stove burners during use can damage the ignition device and cause it to malfunction.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a premixed burner for a commercial stove that can drain water, comprising a volute premixer, a premixer connection joint installed on the upper end of the volute premixer, and a burner head disposed on the upper end of the premixer connection joint. The volute premixer has an interface on its outer side, and an air inlet joint is disposed at the lower end of the volute premixer near the interface. The volute premixer also has an inner rotating plate inside, with fins symmetrically arranged on the outer side of the inner rotating plate, and an ignition needle mounting tube penetrating through the upper surface of the inner rotating plate. The burner head has a flame distribution plate inside, with an ignition needle and a ignition cap arranged from left to right inside the flame distribution plate, and flame holes are opened on the upper surface of the flame holes.

[0006] Preferably, the interior of the volute premixer has a dispersion tube located above the air inlet connector.

[0007] Preferably, there is a gap between the ignition cap and the ignition needle, and the outside of the ignition needle mounting tube is provided with a drain port at the bottom of the burner head.

[0008] Preferably, the inner spiral plate is symmetrically provided with four fins on its exterior, one of which has an installation angle of 45° to the left with the inner spiral plate, another has an installation angle of 45° to the right with the inner spiral plate, and the other two fins also have installation angles of 45° to the left and 45° to the right with the inner spiral plate, respectively.

[0009] Beneficial effects

[0010] This invention provides a commercial stove burner with drainage capability. Compared with the prior art, it has the following advantages: This commercial stove burner with drainage capability reduces heat loss, which is very beneficial for energy conservation and environmental protection. The accumulated water can be completely drained out of the stove body through the notch of the ignition needle tube, preventing it from accumulating in the burner and damaging the ignition device or causing it to fail to ignite properly.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: a premixed burner for a commercial stove that can drain water, including a volute premixer 1, a premixer connection joint 10 installed on the upper end of the volute premixer 1, and a burner head 11 set on the upper end of the premixer connection joint 10. An interface 8 is provided on the outer side of the volute premixer 1, and an air inlet joint 7 is provided at the lower end of the volute premixer 1 near the interface 8. An inner rotating plate 3 is also provided inside the volute premixer 1. Fins 2 are symmetrically arranged on the outer side of the inner rotating plate 3, and an ignition needle mounting tube 4 is provided through the upper surface of the inner rotating plate 3. A flame distribution plate 13 is provided inside the burner head 11. An ignition needle 15 and a ignition cap 14 are arranged from left to right inside the flame distribution plate 13, and a flame hole 12 is opened on the upper surface of the flame distribution plate 13.

[0018] Specifically in this embodiment, the volute premixer 1 has a dispersion tube 9 located above the air inlet connector 7 inside.

[0019] Specifically in this embodiment, there is a gap between the ignition cap 14 and the ignition needle 15, and the outside of the ignition needle mounting tube 4 is provided with a drain port at the bottom of the burner head 11.

[0020] In this specific embodiment, four fins 2 are symmetrically arranged on the outside of the inner spiral plate 3. One fin 2 has an installation angle of 45° to the left with the inner spiral plate 3, another fin 2 has an installation angle of 45° to the right with the inner spiral plate 3, and the other two fins 2 also have installation angles of 45° to the left and 45° to the right with the inner spiral plate 3, respectively.

[0021] During operation (or use), the commercial stove burner with drainage, the volute premixer 1 receives air from the blower through the interface 8, while combustible gas enters the dispersion pipe 9 through the air inlet connector 7, initially dispersing the gas. Under the action of the air, the gas flows along the channel into the premixer. The channel is composed of an inner swirl plate 3. The fins 2 repeatedly turbulently flow the gas-air mixture, forming a turbulent airflow. The fins 2 are welded to the wall of the inner swirl plate 3. The first fin of the first fin 2 is installed at a 45° angle to the left, the second fin 2 at a 45° angle to the right, the third fin 2 at a 45° angle to the left, and so on. This forms a static mixer. The mixed gas is fed into the burner head 11 through the premixer connection connector 10 and then evenly ejected through the flame holes 12 of the flame distribution plate 13. It is then ignited by the ignition burner composed of the ignition cap 14 and the ignition needle 15. In this way, the mixed gas can be fully burned, reducing the emission of harmful gases.

[0022] The ignition needle mounting tube 4 is equipped with a drain outlet, and the tube opening is radially cut with a strip-shaped opening. There is a certain gap between the ignition needle 15 and the ignition needle mounting tube 4. Since the drain outlet of the ignition needle mounting tube 4 is located at the bottom of the burner head 11, when the iron pot leaks water, the water can flow out through the drain outlet, thereby avoiding water accumulation inside the burner head 11 and causing malfunctions.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
