Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations.

The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Example (b): as shown in fig. 1-5, a burner unit for a household gas water heater comprises a fire grate segment 10 and two flame protection plates 30 fixedly connected to two sides of the fire grate segment, respectively, the fire grate segment 10 comprises a first side plate 11, a second side plate 12 and a top plate 13, the upper ends of the first side plate 11 and the second side plate 12 are fixedly connected through the top plate 13, two side walls and the lower ends of the first side plate 11 and the second side plate 12 are directly and fixedly connected, a plurality of flame holes 21 are arranged on the top plate 13, a mixed gas channel 15 is formed inside the first side plate 11 and the second side plate 12, one end of the mixed gas channel 15 is an air inlet 14, the other end is an air outlet 16, the air outlet 16 is communicated with the flame holes 21, a drainage hole 23 is arranged in the fire grate segment 10 on the side away from the air outlet 16, and the lower end of the drainage hole 23 is communicated with the mixed gas channel 15, and the upper end thereof is communicated with the flame holes 21. The lower end of the flame protection plate 30 is directly inserted into the first side plate 11 or the second side plate 12 and is welded and fixed, the structure is compact, no gap exists between the lower end of the flame protection plate and the first side plate or the second side plate, so that secondary air cannot enter the upper part of the flame moving plate from the space between the flame protection plate and the first side plate or between the flame protection plate and the second side plate, and mixed gas above the flame moving plate is blown away, so that poor flame moving is caused; because of the flow rate of the mixed gas and the arrangement of the mixed gas channel, the gas outlet 16 of the mixed gas channel is deviated to one side of the fire row piece at present, which causes the situation that the gas is insufficient in the flame holes 21 far away from the gas outlet 16, and further causes the backfire problem that the flame burns towards the interior of the burner because the burning speed is higher than the jet flow speed.
As shown in fig. 3, the first side plate 11, the second side plate 12 and the top plate 13 are integrally formed, two side walls and lower ends of the first side plate 11 and the second side plate 12 are welded and fixed, the lower ends of the two flame protection plates 30 are respectively welded to the first side plate 11 and the second side plate 12, two cavities 17 are formed between the two flame protection plates 30 and the first side plate 11 and the second side plate 12, a plurality of vent holes 22 are formed in the first side plate 11 and the second side plate 12, and the vent holes 22 are communicated with the cavities 17. As shown in fig. 4, the mixed gas flowing out through the mixed gas passage 15 is partially combusted through the flame holes 21 of the fire damper to form a main flame, and partially flows into the cavity 17 through the vent holes 22 of the first and second side plates 11 and 12 to be combusted at an upper portion of the cavity to form an auxiliary flame which protects the main flame; the drainage holes 23 arranged on the fire row pieces can also ensure the stable combustion of the auxiliary flame far away from the air outlet, and further ensure the stability of the main flame.
As shown in fig. 5, the top plate 13 is a strip-shaped structure, a plurality of flame holes 21 are arranged along the length direction of the top plate, and the flame holes 21 are strip-shaped holes. The first side plate 11 and the second side plate 12 are uniformly provided with a row of vent holes 22 along the length direction thereof, the vent holes 22 are circular holes, and the drainage holes 23 are square through holes.
The upper end of the flame-proof plate 30 protrudes out of the top plate 13, and the flame-proof plate 30 is recessed towards the top plate 13 to form a reinforcing rib 31. The concave reinforcing ribs 31 are formed in the flame-protection plate 30, so that the mixed gas coming out of the vent holes can be blocked, the jet speed of the gas is further reduced, the stable combustion of auxiliary flame is facilitated, the root shape of the flame can be improved, and the combustion sufficiency is improved; the design of the reinforcing ribs improves the strength of the flame holding plate, ensures the consistency of the combustion height of the auxiliary flame, and further ensures the stable combustion of the main flame.
The operation process of the invention is as follows: as shown in fig. 2 and 4, after the gas enters the mixed gas channel through the gas inlet 14, a part of air is simultaneously injected into the single mixed gas channel 15, the gas and the air are mixed in the channel to form mixed gas, the mixed gas enters the flame holes 21 on the flame exhaust piece through the gas outlet 16 and the flow guide holes 23 to burn to form main flame, wherein the flow guide holes 23 introduce the mixed gas into the flame holes far away from the gas outlet, so that stable burning of the main flame far away from the gas outlet is ensured; part of the mixed gas flows into the cavity 17 through the vent holes 22 of the first side plate 11 and the second side plate 12, and is combusted at the upper part of the cavity to form an auxiliary flame, and the auxiliary flame plays a role of protecting the main flame.
It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
