[0039] Additionally, terms including ordinal numbers, such as “first,”“second,” etc., used herein may be used to describe various components, but the components are not limited by the terms, and the terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope and spirit of the present disclosure, a first component may be referred to as a second component, and similarly, the second component may be referred to as the first component. The term “and / or” includes any combination of a plurality of related listed items or any one of the plurality of related listed items.

[0040] FIG. 1 is a perspective view of a burner according to an embodiment of the present disclosure. FIG. 2 is a plan view of a burner according to an embodiment of the present disclosure. FIG. 3 is a cross-sectional view of a burner according to an embodiment of the present disclosure. FIG. 4 is a view illustrating a division part and a cover plate of a burner according to an embodiment of the present disclosure.

[0041] FIG. 2 is a view of a burner 10 of FIG. 1, viewed from a top. FIG. 3 is a view illustrating a cross-section of the burner 10 of FIG. 2, taken along direction A-A′. FIG. 4 is a view illustrating only a chamber division part 400 and a cover plate 120 in the burner 10 of FIG. 1, and illustrating a disassembled state thereof.

[0042] Referring to FIGS. 1 to 4, a burner 10 according to an embodiment may be a device that receives a pre-mixed gas of fuel and air, and ignites the pre-mixed gas to generate a combustion reaction. The burner 10 may include a body part 100, a bracket part 200, a mat part 300, and a chamber division part 400.

[0043] The body part 100 may include a side plate 110 and a cover plate 120 that is coupled to one end of the side plate 110. A chamber 130 that is defined by a specific empty space formed by the side plate 110 and the cover plate 120 may be provided in an interior of the body part 100.

[0044] The side plate 110 may have a hollow cylindrical shape that extends along a reference direction D by a specific length. Here, the reference direction D may be a lower side, but is not limited thereto, and may be relatively determined depending on a disposition direction of the burner 10.

[0045] The side plate 110 may have a shape, of which opposite ends in a lengthwise direction (that is, a direction that is parallel to the reference direction D) are opened. The side plate 110 may have an opening (not illustrated in the drawings) in the reference direction D, and an opening (not illustrated in the drawings) on a side that is opposite to the reference direction D. A cover plate 120 may be coupled to the opening of the side plate 110 in the reference direction D such that the opening may be covered. The opening of the side plate 110 on the opposite side to the reference direction D may be coupled to the bracket part 200 in an opened state.

[0046] As an example, when the burner 10 is mounted on a water heating apparatus (e.g., the water heating apparatus 1 of FIG. 9), the opening of the side plate 110 on the opposite side to the reference direction D may be opened toward a backflow prevention damper (e.g., a backflow prevention damper 30 of FIG. 9), and the pre-mixed gas may flow along the reference direction D to an interior space (that is, the chamber 130) of the side plate 110 through the opening of the side plate 110 on the opposite side to the reference direction D.

[0047] The side plate 110 may include a plurality of distribution holes 111 that are formed to pass through a side surface thereof. The plurality of distribution holes 111 may be formed to extend radially from an inner surface of the side plate 110 toward an outer surface thereof. The plurality of distribution holes 111 may be provided such that a plurality of distribution hole arrays 112, in which slotted holes that extend along the reference direction D are arranged to be spaced apart from each other along the reference direction D are disposed along a circumferential direction.

[0048] Meanwhile, the shapes, sizes, and dispositions of the plurality of distribution holes 111 are not limited to the illustrated form, and may be changed in various forms.

[0049] The side plate 110 may include a first part 110a, in which the plurality of distribution holes 111 are formed, and a second part 110b that extends opposite to the reference direction D from the first part 110a. The first part 110a may be a portion of the side plate 110 that extends by a specific length from an end (e.g., a lower end of the side plate 110 with respect to the drawing) of the side plate 110 in the reference direction D, in an opposite direction (e.g., an upper side) of the reference direction D. The second part 110b is a remaining portion of the side plate 110, except for the first part 110a, and may be blocked while the plurality of distribution holes 111 are not formed.

[0050] That is, when the reference direction D is a lower side, a position that is spaced downward by a specific interval from an upper end of the side plate 110 may be an upper end of a portion (or area), at which the plurality of distribution holes 111 are formed, and a lower end of the portion (or area), at which the plurality of distribution holes 111 are formed, may be located at a lower end of the side plate 110.

[0051] Meanwhile, the first part 110a and the second part 110b may not be physically separated portions, and may be understood as referring to a portion, at which the plurality of distribution holes are formed, and a remaining portion, at which the plurality of distribution holes are not formed, for convenience of description.

[0052] An outer surface of the first part 110a of the side plate 110 may be covered by the mat part 300, and an outer surface of the second part 110b of the side plate 110 may not be covered by the mat part 300 and may be exposed as an exterior of the burner 10. The plurality of distribution holes 111 become hidden and invisible by the mat part 300 with respect to an exterior of the body part 100.

[0053] According to the embodiment illustrated in FIG. 3, ends of the plurality of distribution holes 111 on the opposite side to the reference direction D may be located to be spaced apart from a boundary (that is, an end of the first part 110a on the opposite side to the reference direction D) between the first part 110a and the second part 110b, in the reference direction D at a specific interval. That is, an area, in which the plurality of distribution holes 111 are not formed, may partially exist at an upper portion of the first part 110a.

[0054] The cover plate 120 may be coupled to an end of the side plate 110 in the reference direction D to cover the opening of the side plate 110 in the reference direction D. The cover plate 120 is coupled to the side plate 110 to form a chamber 130 that is a space defined by inner surfaces of the side plate 110 and the cover plate 120, in an interior of the body part 100.

[0055] The cover plate 120 may be formed in a shape corresponding to the side plate 110. For example, the cover plate 120 may be formed in a disk shape corresponding to the cylindrical side plate 110, and may be disposed perpendicularly to the reference direction D.

[0056] The cover plate 120 may include a plate part 121 that is inserted into an opening of the side plate 110 in the reference direction D and is coupled to an end of the side plate 110 in the reference direction D, and a protruding part 122 that protrudes in a ring shape from the plate part 121 toward the opposite side to the reference direction D.

[0057] The protruding part 122 may be formed at a position that is spaced apart from a periphery of the plate part 121 toward an inner side at a specific interval. The protruding part 122 may protrude from one surface (e.g., an upper surface with respect to the drawing) of the plate part 121 that faces the opposite side to the reference direction D. As the protruding part 122 protrudes in a ring shape from the plate part 121, a recess 123 may be formed inside the protruding part 122.

[0058] The protruding part 122 may be a component, to which the chamber division part 400 is coupled. For example, at least some of the division plates 410, 420, and 430 of the chamber division part 400 may be fixed and coupled to the protruding part 122 through welding or the like. Cover plate 120 may be configured such that the division plates 410, 420, and 430 are spaced apart from the plate part 121 at a specific interval along the reference direction D, as the recess 123 is formed by the protruding part 122.

[0059] The bracket part 200 may be coupled to the body part 100. For example, the bracket part 200 may be coupled to an end of the side plate 110 on the opposite side to the reference direction D. The bracket part 200 may be formed in a ring shape such that the pre-mixed gas passes through the bracket part 200 and is introduced into the chamber 130 of the body part 100.

[0060] The bracket part 200 may be coupled to a case (e.g., the case 40 in FIG. 9) of the water heating apparatus (e.g., the water heating apparatus 1 in FIG. 9) while being coupled to the body part 100, to mount the burner 10 on the case 40. The bracket part 200 may include a ring-shaped coupling part 210 that is coupled to the side plate 110, and a flange part 220 that extends from the coupling part 210 in an outward direction that is perpendicular to a central axis CA. The coupling part 210 may be coupled to an inner surface of an end (e.g., an upper end) of the side plate 110 on the opposite side to the reference direction D. The flange part 220 may be perpendicular to the reference direction D and may be coupled to the case 40.

[0061] The mat part 300 may be formed of metal fiber for ignition and may be configured to cover an outer peripheral surface of the side plate 110. The mat part 300 may cover an area (that is, the first part 110a) of the outer peripheral surface of the side plate 110, in which the distribution holes 111 are formed. For example, the first part 110a of the side plate 110 may be a portion that is covered by the mat part 300, and the second part 110b of the side plate 110 may refer to a remaining portion, other than the first part 110a, which is not covered by the mat part 300.

[0062] The mat part 300 may be formed in a hollow cylindrical shape to cover an outer peripheral surface of the cylindrical side plate 110. The pre-mixed gas distributed through the distribution holes 111 may be ignited to form flames on the mat part 300.

[0063] The chamber division part 400 may be configured to divide a partial section of the chamber 130 in an interior of the body part 100, which extends along a direction of the central axis CA, into one or more spaces. The chamber division part 400 may be disposed in an interior of the first part 110a of the side plate 110 and be coupled to the cover plate 120, to divide a partial section of the chamber 130, which is surrounded by the first part 110a, into a plurality of spaces arranged along the circumferential direction.

[0064] The chamber division part 400 may include a plurality of division plates 410, 420, and 430 that are disposed perpendicularly to the cover plate 120. For example, the plurality of division plates 410, 420, and 430 may be disposed perpendicularly to the cover plate 120, so that the chamber 130 may be divided into a plurality of spaces that are separated and divided along the circumferential direction. The plurality of division plates 410, 420, and 430 may be welded and fixed to an upper surface of the cover plate 120. For example, although not denoted by a reference numeral, the plurality of division plates 410, 420, and 430 may include a coupling part that is welded to the cover plate 120.

[0065] By way of example, the chamber division part 400 may divide the chamber 130 in the interior of the first part 110a into four spaces. For example, the chamber division part 400 may include a first division plate 410 that is coupled to the cover plate 120 to divide the chamber 130 into two spaces, a second division plate 420 that is coupled to a first surface 411 of the first division plate 410 and is coupled to the cover plate 120 to divide a space on the first-surface side of the first division plate 410 into two spaces, and a third division plate 430 that is coupled to a second surface (not illustrated) of the first division plate 410, which is opposite to the first surface 411, and coupled to the cover plate 120 to divide a space on the second-surface side of the first division plate 410 into two spaces. Here, with reference to the drawings, the first surface 411 of the first division plate 410 may face a left lower side, and the second surface of the first division plate 410, which is an opposite surface of the first surface 411, may face a right upper side.

[0066] The second division plate 420 and the third division plate 430 may have the same size, and may be welded and fixed to the first surface 411 and the second surface of the first division plate 410, respectively. For example, the second division plate 420 and the third division plate 430 may include coupling ends 421 and 431 that are coupled to the first division plate 410, respectively, and the coupling ends 421 and 431 may be provided in a curved shape at ends of the second division plate 420 and the third division plate 430.

[0067] The first division plate 410, the second division plate 420, and the third division plate 430 may have the same length (that is, the same longitudinal length) along the reference direction D, and the first division plate 410 may have an extent that is greater than those of the second division plate 420 and the third division plate 430. That is, a transverse length of the first division plate 410 may be formed to be greater than transverse lengths of the second division plate 420 and the third division plate 430.

[0068] Opposite transverse ends of the first division plate 410 may contact an inner surface of the side plate 110, or may be spaced apart from the inner surface of the side plate 110. Similarly, transverse ends of the second division plate 420 and the third division plate 430 may contact an inner surface of the side plate 110, or may be spaced apart from the inner surface of the side plate 110.

[0069] According to the illustrated embodiment, the chamber division part 400 may be provided to divide the chamber 130 in the first part 110a into four equal portions. For example, the first division plate 410 may be coupled to overlap the central axis CA of the body part 100 (or the side plate 110), the second division plate 420 may be coupled to be perpendicular to the first surface 411 of the first division plate 410, and the third division plate 430 may be coupled to be perpendicular to the second surface of the first division plate 410. Here, the central axis CA means an axis that is parallel to the reference direction D and passes a center of the side plate 110. That is, the first division plate 410 divides the chamber 130 into two portions, and the second division plate 420 and the third division plate 430 further divide the two divided spaces into two portions, respectively.

[0070] However, it is by way of example, and the chamber division part 400 may divide the chamber 130 into four spaces, at least some of which may have different volumes or sizes. Furthermore, the number of divisions of the chamber 130 is not limited to four, and may be variously modified. An embodiment in which the chamber 130 is divided into a different number of spaces will be described in detail below, with reference to FIGS. 6 and 7.

[0071] The chamber division part 400 may be formed such that ends of the plurality of division plates 410, 420, and 430 on the opposite side to the reference direction D do not exceed the first part 110a of the side plate 110. Furthermore, the chamber division part 400 may be formed such that ends of the plurality of division plates 410, 420, and 430 on the opposite side to the reference direction D do not exceed ends of the distribution holes 111 on the opposite side to the reference direction D, and here, ends of the plurality of distribution holes 111 on the opposite side to the reference direction D may be referenced as an end of the distribution hole array 112 on the opposite side to the reference direction D, that is, an uppermost end thereof in FIG. 3. That is, in a cross-section of the burner 10, taken along the reference direction D, the chamber division part 400 may not be located higher than the plurality of distribution holes 111 and / or the mat part 300.

[0072] The chamber division part 400 may be formed such that ends of the plurality of division plates 410, 420, and 430 on the opposite side to the reference direction D are located within a reference interval G from ends of the plurality of distribution holes 111 on the opposite side to the reference direction D.

[0073] The structure is designed in consideration of the fact that, when heights of the plurality of division plates 410, 420, and 430 exceed those of the plurality of distribution holes 111 or are excessively lower than those of the plurality of distribution holes 111, instability of flow in the chamber 130 may occur.

[0074] In this way, because the chamber 130 is divided into a plurality of spaces through the chamber division part 400, noise generated during combustion may be reduced. Specifically, unlike the burner 10 according to the present disclosure, when the chamber 130 is not divided into a plurality of spaces, a flow of pre-mixed gas exhibits turbulent-flow characteristics, so that, during formation of a combustion flame, unstable noise caused by an internal flow and the flame may occur with the side plate 110 serving as a boundary. According to an embodiment of the present disclosure, by disposing the chamber division part 400 that divides the chamber 130 into a plurality of spaces, a flow of pre-mixed gas in the chamber 130 may be stabilized into a laminar flow, so that noise generated during flame formation may be reduced.

[0075] FIG. 5 is a cross-sectional view of a burner according to an embodiment of the present disclosure.

[0076] FIG. 5 illustrates a burner 10′, unlike the burner 10 illustrated in FIG. 3, in which heights of the chamber division part 400 and the plurality of distribution holes 111 coincide with each other, and, in addition, these heights are formed to coincide with a height of the mat part 300.

[0077] The burner 10′ of FIG. 5 may be substantially the same as the burner 10 of FIGS. 1 to 4, except for modified portions in which heights of the chamber division part 400 and the plurality of distribution holes 111 are changed. Hereinafter, repeated descriptions of the above description will be omitted, and the following description will focus on the changed parts.

[0078] Referring to FIG. 5, the side plate 110 may be formed such that ends of the plurality of distribution holes 111 on the opposite side to the reference direction D coincide with an end of the mat part 300 on the opposite side to the reference direction D. For example, on a cross-section of the burner 10′ taken along the reference direction D, an end of each of the plurality of distribution holes 111 and the mat part 300 on the opposite side to the reference direction D may be located on an imaginary line L that is perpendicular to the reference direction D. Here, the imaginary line L may be a boundary between the first part 110a and the second part 110b of the side plate 110. That is, in the burner 10 of FIG. 5, uppermost ends of the plurality of distribution holes 111 may be portions, at which the first part 110a ends and the second part 110b begins.

[0079] The chamber division part 400 may be formed such that ends of the plurality of division plates 410, 420, and 430 on the opposite side to the reference direction D coincide with ends of the plurality of distribution holes 111 on the opposite side to the reference direction D. For example, on a cross-section of the burner 10′ taken along the reference direction D, the plurality of distribution holes 111 may not be located on the opposite side to the reference direction D relative to the chamber division part 400, and may be covered by the plurality of division plates 410, 420, and 430.

[0080] According to the embodiment illustrated in FIG. 5, ends of the plurality of division plates 410, 420, and 430, the plurality of distribution holes 111, and the mat part 300 on the opposite side to the reference direction D may coincide with each other. That is, on a cross-section of the burner 10′ taken along the reference direction D, ends of the plurality of division plates 410, 420, and 430, the plurality of distribution holes 111, and the mat part 300 on the opposite side to the reference direction D may coincide with the imaginary line L.

[0081] In this way, the height of the chamber division part 400 is made to coincide with upper ends of the plurality of distribution holes 111 to be optimized, so that a noise-reduction effect may be increased.

[0082] FIG. 6 is a view illustrating a first modified example of a chamber division part according to an embodiment of the present disclosure. FIG. 7 is a view illustrating a second modified example of a chamber division part according to an embodiment of the present disclosure.

[0083] FIGS. 6 and 7 are views illustrating modified embodiments in which, unlike the burner 10 of FIGS. 1 to 4, the chamber division part 400 is provided to divide the chamber 130 of the side plate 110 into six and eight spaces.

[0092] Meanwhile, FIGS. 2, 6, and 7 illustrate forms, in which the chamber division part 400 divides the chamber 130 into four, six, and eight spaces, respectively, but this is by way of example, and the chamber division part 400 according to the present disclosure is not limited to a form, in which the chamber 130 is divided into an even number of spaces. For example, the chamber division part 400 may be configured to divide the chamber 130 into an odd number of spaces, such as three, five, or seven spaces, and the number, shapes, and coupling structures of the plurality of division plates may be modified correspondingly.

[0093] FIG. 8 is a view illustrating a third modified example of a chamber division part according to an embodiment of the present disclosure.

[0094] FIG. 8 is a view illustrating a modified example, in which one or more through-holes 480 are formed in at least one of the division plates 410, 420, and 430 of the chamber division part 400.

[0095] FIG. 8 illustrates an embodiment, in which a through-hole 480 is formed in the chamber division part 400 illustrated in FIGS. 1 to 4, but this is for convenience of description, and the modified embodiment according to FIG. 8 may be applied in the same manner to the chamber division part 400 of FIGS. 6 and 7 described above.

[0096] Referring to FIG. 8, the chamber division part 400 may be configured such that one or more through-holes 480 are formed in at least one of the plurality of division plates 410, 420, and 430. For example, according to the illustrated example, two through-holes 480 may be formed in the first division plate 410, and one through-hole 480 may be formed in each of the second division plate 420 and the third division plate 430.

[0097] However, this is merely by way of example, and the number of the division plates 410, 420, and 430, in which the through-hole 480 is formed, may be variously modified, and the sizes, positions, shapes, and / or numbers of the through-holes 480 formed in specific division plates are not particularly limited and may also be variously changed.

[0098] Because the through-hole 480 is formed in the plurality of division plates 410, 420, and 430, the chamber 130 is separated and partitioned by the plurality of division plates 410, 420, and 430, so that combustion noise is reduced and spatial noise that may occur due to the plurality of separated spaces may be additionally avoided.
