The burner in a water heater generally comprises a fire grate and a flow passage for providing gas for the fire grate, wherein a shell structure on the burner at least at the position corresponding to the flow passage is formed by joining two metal plates. In the prior art, two metal plates are generally welded and fixed, the welding process is relatively complex, and the electrode pressure during welding easily causes the bending deformation of the metal plates, so that the two metal plates are in butt joint dislocation, the sealing effect of the two metal plates is reduced, insufficient combustion in a combustor is easily caused, and the content of carbon monoxide exceeds the standard.
In view of the above, the present invention provides a burner applied to a water heater, which may be a product and an apparatus for home bathing, heating, etc. using high-temperature hot water generated by gas combustion. Fig. 1 to 3 show an embodiment of a burner according to the present invention.
Referring to fig. 1 to 3, a combustor 1 according to the present invention includes a housing 10, a flow channel 100 is formed inside the housing 10, at least two flow channel segments 101 of the flow channel 100 are oppositely disposed at intervals, and the housing 10 defines a first region 102 at the intervals; the housing 10 includes two plates 110 enclosing the flow channel 100, and each of the plates 110 has a first portion 111 corresponding to the first region 102, so that when the two plates 110 are joined, the two first portions 111 are riveted.
In the technical scheme provided by the utility model, the two first parts 111 are riveted integrally when the two plate bodies 110 are jointed, so that compared with the scheme that a plurality of welding points are required to be arranged in the traditional welding process, the forming process of the combustor 1 is facilitated to be simplified, the deformation of the plate bodies 110 in the jointing process can be reduced, and the jointing quality of the two plate bodies 110 is improved; in addition, the airflow between the two flow channel sections 101 that are arranged at the relative intervals is easy to mutually flee, and the riveting part 210 is arranged between the two flow channel sections 101, so that the part easy to flee can be effectively sealed in a targeted manner, the overall sealing effect of the combustor 1 is improved, and the combustion quality of the combustor 1 is improved.
It can be understood that the burner 1 in the water heater is generally used for igniting the combustion-supporting gas and then burning the combustion-supporting gas to form high-temperature flue gas, and the high-temperature flue gas is used for exchanging heat with tap water so as to prepare hot water. In order to achieve the above functions, the burner 1 generally comprises two parts connected in sequence, wherein the first part is used for forming the flow channel 100, the second part is used for forming the fire grate 300, the flow channel 100 is used for providing combustion-supporting gas for the fire grate 300, and the combustion-supporting gas can be air, fuel gas or a mixed gas of air and fuel gas; the fire grate 300 is ignited to burn after being connected with combustion-supporting gas.
The housing 10 mainly refers to a portion of the combustor 1 for forming the flow passage 100. At least two flow channel segments 101 of the flow channel 100 are arranged oppositely and at intervals. The relative positions are not limited to that the extending directions of the two flow channel segments 101 need to be kept parallel, and may be arranged at an included angle. Because the two flow channel sections 101 are arranged oppositely, the gas flowing through each of the two flow channel sections 101 may flow in a direction beyond the direction close to each other, so that the gas flowing through the two flow channel sections 101 flows through each other, and a part of the gas cannot flow to the fire grate 300 along a specified path to be combusted, so that the combustor 1 is insufficient in combustion, harmful gas such as carbon monoxide is easily generated, and the combustion quality of the combustor 1 is reduced.
The first region 102 is located at the interval between the two flow path segments 101, that is, when the gas in the two flow path segments 101 flows through each other, the gas must pass through the first region 102. Therefore, by performing the blocking process on the first region 102, the gas in the two flow path segments 101 can be effectively prevented from flowing into each other.
The housing 10 may be generally formed by joining at least two plate bodies 110, the shape of the two plate bodies 110 is not limited, and the two plate bodies 110 may be symmetrically disposed about the middle section of the flow channel 100, and of course, the shape and size of the two plate bodies 110 may also be differently disposed, as long as the flow channel 100 is formed by assembling the two plate bodies 110.
When the two plate bodies 110 are joined, the first portions 111 of the two plate bodies 110 may be riveted at the same time, so that the first region 102 of the casing 10 is blocked by the riveted portions, thereby facilitating effective sealing between the two flow channel sections 101. Specifically, for example, when the two plate bodies 110 are integrally molded in a mold, the first portions 111 of the two plate bodies 110 may be punched by a punching operation, thereby integrally caulking the two first portions 111.
In the above, when at least two flow passages 100 are provided, at least a part of each of the two flow passages 100 constitutes the two flow passage sections 101. The two flow channels 100 may independently provide gas for the fire grate 300, or may be communicated with each other at a position other than the first region 102.
When there is one flow channel 100, referring to fig. 1 to 3, in an embodiment, the flow channel 100 is curved in an arc shape to form a concave arc side and a convex arc side; the housing 10 defines the first region 102 at the side corresponding to the concave arc.
For example, when the housing 10 has a first side and a second side that are opposite to each other, the flow channel 100 extends from the first side toward the second side and then bends and extends toward the first side, and at this time, a side of the flow channel 100 close to the first side is the concave arc side, and a side of the flow channel 100 close to the second side is the convex arc side. Because the flow channel 100 extends towards the second side and then bends towards the first side, the part of the flow channel 100 connected with the bent part forms two flow channel sections 101, and the flow direction of the gas flowing through the two flow channel sections 101 is changed, so that blow-by gas is easily generated.
Of course, the entire flow passage 100 of the burner 1 may be bent many times to form a plurality of concave arc sides, and each concave arc side defines one first region 102.
There are various ways to rivet the two first portions 111, in an embodiment, the riveting portion 210 may be disposed on only one of the two plate bodies 110, and the other plate body 110 is directly riveted by the riveting portion 210, but in order to improve the riveting tightness and reduce the deformation probability of the plate body 110, in this embodiment, one of the two first portions 111 is provided with the riveting portion 210, and the other corresponding to the riveting portion 210 is provided with the matching portion 220, and the riveting portion 210 is riveted with the matching portion 220. The arrangement of the riveting portion 210 and the matching portion 220 is helpful for forming a one-to-one corresponding riveting relationship, so that when the riveting portion 210 and the matching portion 220 are riveted smoothly, an alignment requirement is basically achieved between the two plate bodies 110, and the two plate bodies 110 are prevented from being dislocated with each other during assembly, which is favorable for preventing poor quality.
The specific schemes of the riveting portion 210 and the matching portion 220 are various:
in an embodiment, the riveting portion 210 and the matching portion 220 are riveting holes penetrating through the corresponding plate body 110, and the riveting portion 210 and the matching portion 220 are riveted and fixed by butting two additionally arranged rivets against the two riveting holes.
Or in an embodiment, the riveting portion 210 is a groove 221, and the matching portion 220 is a protrusion 211 that is in concave-convex fit with the groove 221. The shape of the inner groove of the groove 221 is matched with the shape of the outer wall of the protrusion 211, and the size of the inner groove of the groove 221 can be equal to the external size of the protrusion 211 or slightly smaller than the external size of the protrusion 211, so that when the groove 221 is riveted with the protrusion 211, the side groove wall of the groove 221 can apply clamping force to the protrusion 211, the protrusion 211 is limited to be separated from the groove 221, and sealing and fixing at the position are facilitated.
The shape of the protrusion 211 is not limited, and the cross section thereof may be substantially circular, quasi-circular, elliptical, polygonal, or other irregular shapes. Furthermore, the joints between the grooves 221 and the corresponding plate bodies 110, the joints between the protrusions 211 and the corresponding plate bodies 110, the joints between the groove walls in the grooves 221, and the joints between the outer side walls of the protrusions 211 may all be in arc transition to form smooth guide surfaces, which facilitates accurate butt joint of the grooves 221 and the protrusions 211, facilitates processing and forming, and can avoid stress concentration at corners.
Since the first region 102 is planar and occupies a certain area, the protrusion 211 may extend along the length direction of the first region 102 in order to seal between the two flow channel segments 101. The length direction of the first region 102 corresponds to a direction in which the first region 102 is away from the convex arc side.
The plurality of protrusions 211 may be intermittently arranged along the length direction of the first region 102, the plurality of protrusions 211 are approximately linearly arranged, and the size and shape of the plurality of protrusions 211 and the distance between two adjacent protrusions 211 are set to be the same as much as possible, so that when the riveting operation is performed, the stress at the first region 102 is approximately balanced, and the first portion 111 of the plate body 110 is prevented from being deformed.
The protrusion 211 may be continuously disposed as one along the length direction of the first region 102, that is, the protrusion 211 may be disposed in a longitudinal shape. Specifically, the protrusions 211 maintain a uniform width in the longitudinal direction of the first region 102 as much as possible, which also helps prevent the first portion 111 of the plate body 110 from being deformed.
In addition, the protrusion 211 may be directly isolated between the two flow channel segments 101 regardless of the shape of the first region 102.
Alternatively, the number of the protrusions 211 arranged and the shape and size of the protrusions can be set to match the shape of the first region 102. For example, when the first region 102 has an elongated shape with substantially the same width, the protrusions 211 may be arranged substantially linearly; when the first region 102 is substantially triangular, the protrusions 211 may be substantially triangular, or at least two protrusions 211 may be provided, and one end of each of the two protrusions 211 is connected and the other end extends obliquely away from each other to match the extending shape of the first region 102.
Of course, the number of the protrusions 211 arranged and the size of the protrusions 211 can be set to match the size of the first region 102. For example, in this embodiment, since the flow channel 100 is curved in an arc shape, the first region 102 defined by the concave arc side is approximately gradually wider in a direction away from the convex arc side, based on which the protrusion 211 includes two rib segments 211a connected in sequence, and the two rib segments 211a are arranged at a crossed included angle. For convenience of understanding, the two rib segments 211a are a first rib segment and a second rib segment, respectively, the first rib segment extends in a direction from the convex arc side to the concave arc side to divide the first region 102 into two sections, and when the areas of the two sections of the first region 102 are substantially the same, the second rib segment may be arranged in line with the first rib segment; when there is a difference in area between two sections of the first region 102, the second rib section may extend obliquely from any position of the first rib section toward the section with the larger area.
Based on any of the above embodiments, the distance between any one of the riveting portion 210 and the matching portion 220 is equivalent to the distance between two runner segments 101. Specifically, when the rivet 210 is the elongated protrusion 211 as described above, the protrusion 211 is disposed on the center line of the first region 102 as much as possible. The central line is understood that edge lines are formed on the concave arc sides of the two runner sections 101, respectively, and the edge lines of the two runner sections 101 may be substantially parallel, and at this time, the central line is also a line body between the two edge lines and equidistant from the two edge lines; when the two edge lines are arranged in a crossed included angle mode, wherein one end of each edge line is connected, and the other end of each edge line extends towards the direction away from the other end of each edge line, the central line is also close to the angle bisector of the two edge lines. Thus, the deformation of the plate body 110 during riveting can be effectively reduced.
Of course, the groove 221 matched with the protrusion 211 may also penetrate through the corresponding plate body 110 to be in a through hole shape, so as to meet the actual application requirement of the plate body 110.
In addition to the protrusion 211 and the groove 221, in an embodiment, when the first region 102 extends to the edge of the housing 10, the rivet 210 may be a flange 212 protruding from the corresponding edge of the plate 110 and folded toward the matching portion 220, and the flange 212 is riveted with the matching portion 220. It can be understood that, compared with the groove 221 and the protrusion 211, the arrangement of the turned-over edge 212 can reduce the structural deformation at the edge of the casing 10, thereby avoiding the crack at the edge of the casing 10, the turned-over edge 212 is convenient for riveting operation, and can strengthen the tight connection between the two plate bodies 110 at the edge.
Then, the corresponding portion of the plate 110 that is riveted and press-fitted with the flange 212 may be directly provided as a flat surface, or a pressing groove 222 may be provided at the corresponding portion of the plate 110, the pressing groove 222 constitutes the fitting portion 220, and the pressing groove 222 is adapted to the shape of the flange 212 to increase the riveting strength of the two.
Furthermore, in the above embodiment, the riveting portion 210 and/or the matching portion 220 are/is pre-arranged on the corresponding plate body 110, for example, when the riveting portion 210 is a protrusion 211, the protrusion 211 can be pre-arranged on the plate body 110, so that when the riveting portion 210 is riveted with the matching portion 220, the accurate butt joint of the two plate bodies 110 is completed; alternatively, the riveting portion 210 and/or the fitting portion 220 may be integrally formed by crimping when the two plate bodies 110 are joined. That is, before the two plate bodies 110 are joined, the riveting portion 210 and/or the matching portion 220 are not exposed and disposed on the corresponding plate bodies 110, and the riveting portion 210 and/or the matching portion 220 can be punched and riveted by, for example, a punching die when the two plate bodies 110 are joined, which does not simplify the process.
Furthermore, the utility model also provides a water heater comprising a burner 1 as described above. It should be noted that, the detailed structure of the burner 1 in the water heater can refer to the above-mentioned embodiment of the burner 1, and is not described herein again; since the burner 1 is used in the water heater of the present invention, the embodiment of the water heater 1 of the present invention includes all technical solutions of all embodiments of the burner 1, and the achieved technical effects are also completely the same, and are not described herein again.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
