[0030] Figure 1 This is a perspective view of a burner according to an embodiment of the present disclosure. Figure 2 This is a plan view of a burner according to an embodiment of the present disclosure. Figure 3 This is a cross-sectional view of a burner according to an embodiment of the present disclosure. Figure 4 This is a view showing the partition and cover of a burner according to an embodiment of the present disclosure.
[0031] Figure 2 yes Figure 1 A top view of the burner 10. Figure 3 It is shown Figure 2 A view of a cross section taken along direction A-A' of the burner 10. Figure 4 It only shows Figure 1 The view shows the chamber partition 400 and cover plate 120 in the burner 10 and their disassembled state.
[0032] Reference Figures 1 to 4 According to one embodiment, the burner 10 can be a device that receives a premixed gas of fuel and air and ignites the premixed gas to produce a combustion reaction. The burner 10 may include a main body 100, a support 200, a pad 300, and a chamber partition 400.
[0033] The main body 100 may include a side plate 110 and a cover plate 120 connected to one end of the side plate 110. A chamber 130 defined by a specific empty space formed by the side plate 110 and the cover plate 120 may be disposed inside the main body 100.
[0034] The side plate 110 may have a hollow cylindrical shape extending a certain length along a reference direction D. Here, the reference direction D may be the lower side, but is not limited to this, and may also be determined relative to the configuration direction of the burner 10.
[0035] Side plate 110 may have a shape with open opposite ends in the longitudinal direction (i.e., the direction parallel to the reference direction D). Side plate 110 may have an opening in the reference direction D (not shown in the figures) and an opening on the side opposite to the reference direction D (not shown in the figures). Cover plate 120 may be attached to the opening of side plate 110 in the reference direction D such that the opening can be covered. The opening of side plate 110 on the side opposite to the reference direction D may be attached to bracket portion 200 in the open state.
[0036] As an example, when burner 10 is installed in a water heating device (e.g., Figure 9 When the water heating device 1) is installed, the opening of the side plate 110 on the side opposite to the reference direction D can face the anti-backflow damper (e.g., Figure 9 The backflow damper 30 is open, and the premixed gas can flow along the reference direction D into the interior space (i.e., chamber 130) of the side plate 110 through the opening on the side opposite to the reference direction D.
[0037] The side plate 110 may include a plurality of distribution holes 111 formed through its side surface. The plurality of distribution holes 111 may be formed to extend radially from the inner surface of the side plate 110 toward its outer surface. The plurality of distribution holes 111 may be configured such that a plurality of distribution hole arrays 112 are arranged in a circumferential direction, in which slots extending along a reference direction D are arranged to be spaced apart from each other along the reference direction D.
[0038] Meanwhile, the shape, size and configuration of the multiple distribution holes 111 are not limited to the form shown in the figure, and can be changed in various forms.
[0039] The side plate 110 may include a first portion 110a and a second portion 110b. The first portion 110a has a plurality of dispensing holes 111 formed therein, and the second portion 110b extends from the first portion 110a in the opposite direction to the reference direction D. The first portion 110a may be a portion of the side plate 110 extending a certain length from its end in the reference direction D (e.g., the lower end of the side plate 110 relative to the figures) in a direction opposite to the reference direction D (e.g., upwards). The second portion 110b is the remaining portion of the side plate 110 excluding the first portion 110a, and may be blocked even if the plurality of dispensing holes 111 are not formed therein.
[0040] That is, when the reference direction D is downward, the position that is a certain interval from the upper end of the side plate 110 can be the upper end of the part (or area) where a plurality of distribution holes 111 are formed, and the lower end of the part (or area) where a plurality of distribution holes 111 are formed can be located at the lower end of the side plate 110.
[0041] Meanwhile, the first part 110a and the second part 110b may not be physically separate parts, and for ease of description, they can be understood as referring to the part where a plurality of distribution holes are formed and the remaining part where a plurality of distribution holes are not formed.
[0042] The outer surface of the first portion 110a of the side plate 110 can be covered by the pad portion 300, and the outer surface of the second portion 110b of the side plate 110 can be left uncovered by the pad portion 300 and can be exposed as the exterior of the burner 10. The plurality of dispensing holes 111 are hidden and invisible by the pad portion 300 relative to the exterior of the main body 100.
[0043] according to Figure 3 In the illustrated embodiment, the ends of the plurality of dispensing holes 111 on the side opposite to the reference direction D may be spaced apart from the boundary between the first portion 110a and the second portion 110b (i.e., the end of the first portion 110a on the side opposite to the reference direction D) by a specific interval in the reference direction D. That is, the area in which the plurality of dispensing holes 111 are not formed may partially exist in the upper part of the first portion 110a.
[0044] The cover plate 120 can be attached to the 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 attached to the side plate 110 to form a cavity 130 inside the main body 100, the cavity 130 being a space defined by the inner surfaces of the side plate 110 and the cover plate 120.
[0045] The cover plate 120 can be formed in a shape corresponding to the side plate 110. For example, the cover plate 120 can be formed in a disk shape corresponding to the cylindrical side plate 110, and can be arranged perpendicular to the reference direction D.
[0046] The cover plate 120 may include a plate portion 121 and a protrusion 122. The plate portion 121 is inserted into an opening in the reference direction D of the side plate 110 and connected to the end of the side plate 110 in the reference direction D. The protrusion 122 protrudes in an annular shape from the plate portion 121 toward a side opposite to the reference direction D.
[0047] The protrusion 122 may be formed at a position spaced inward from the periphery of the plate portion 121. The protrusion 122 may protrude from a surface of the plate portion 121 facing the side opposite to the reference direction D (e.g., the upper surface relative to the drawing). When the protrusion 122 protrudes annularly from the plate portion 121, a recess 123 may be formed inside the protrusion 122.
[0048] The protrusion 122 may be a component connected to the chamber partition 400. For example, at least some of the partition plates 410, 420, and 430 of the chamber partition 400 may be fixed and connected to the protrusion 122 by welding or the like. The cover plate 120 may be configured such that the partition plates 410, 420, and 430 are spaced apart from the plate portion 121 at specific intervals along the reference direction D, because the recess 123 is formed by the protrusion 122.
[0049] The support portion 200 can be connected to the main body portion 100. For example, the support portion 200 can be connected to the end of the side plate 110 on the side opposite to the reference direction D. The support portion 200 can be formed in annular shape so that the premixed gas passes through the support portion 200 and is introduced into the chamber 130 of the main body portion 100.
[0050] The bracket 200 can be connected to a water heating device (e.g., Figure 9 The housing of the water heating device 1) (e.g., Figure 9 The burner 10 is mounted on the housing 40 and simultaneously connected to the main body 100. The support portion 200 may include an annular connecting portion 210 that connects to the side plate 110 and a flange portion 220 extending outward from the connecting portion 210 in a direction perpendicular to the central axis CA. The connecting portion 210 may be connected to the inner surface of the end (e.g., the upper end) of the side plate 110 on the side opposite to the reference direction D. The flange portion 220 may be perpendicular to the reference direction D and may be connected to the housing 40.
[0051] The pad 300 may be formed of metal fibers for ignition and may be configured to cover the outer peripheral surface of the side plate 110. The pad 300 may cover the area (i.e., the first portion 110a) of the outer peripheral surface of the side plate 110 where the dispensing holes 111 are formed. For example, the first portion 110a of the side plate 110 may be the portion covered by the pad 300, and the second portion 110b of the side plate 110 may refer to the remaining portion of the side plate 110 that is not covered by the pad 300, excluding the first portion 110a.
[0052] The pad 300 can be formed as a hollow cylinder to cover the outer peripheral surface of the cylindrical side plate 110. The premixed gas dispensed through the dispensing hole 111 can be ignited to form a flame on the pad 300.
[0053] The chamber partition 400 can be configured to divide a portion of the chamber 130 inside the main body 100 extending along the central axis CA into one or more spaces. The chamber partition 400 can be disposed inside the first portion 110a of the side plate 110 and connected to the cover plate 120 to divide the portion of the chamber 130 surrounded by the first portion 110a into multiple spaces arranged in a circumferential direction.
[0054] The chamber partition 400 may include a plurality of partition plates 410, 420, and 430 disposed perpendicular to the cover plate 120. For example, the plurality of partition plates 410, 420, and 430 may be disposed perpendicular to the cover plate 120 such that the chamber 130 may be divided into a plurality of spaces separated and divided along a circumferential direction. The plurality of partition plates 410, 420, and 430 may be welded and fixed to the upper surface of the cover plate 120. For example, although not indicated by reference numerals, the plurality of partition plates 410, 420, and 430 may include connecting portions welded to the cover plate 120.
[0055] For example, the chamber partition 400 can divide the chamber 130 inside the first part 110a into four spaces. For example, the chamber partition 400 may include a first partition plate 410, a second partition plate 420, and a third partition plate 430. The first partition plate 410 is connected to the cover plate 120 to divide the chamber 130 into two spaces. The second partition plate 420 is connected to the first surface 411 of the first partition plate 410 and to the cover plate 120 to divide the space on the first surface side of the first partition plate 410 into two spaces. The third partition plate 430 is connected to the second surface (not shown) of the first partition plate 410 opposite to the first surface 411 and to the cover plate 120 to divide the space on the second surface side of the first partition plate 410 into two spaces. Here, referring to the drawings, the first surface 411 of the first partition plate 410 may face the lower left side, and the second surface of the first partition plate 410, which is the surface opposite to the first surface 411, may face the upper right side.
[0056] The second partition plate 420 and the third partition plate 430 may have the same dimensions and may be welded and fixed to the first surface 411 and the second surface of the first partition plate 410, respectively. For example, the second partition plate 420 and the third partition plate 430 may include connecting ends 421 and 431 that are respectively connected to the first partition plate 410, and the connecting ends 421 and 431 may be arranged in a curved shape at the ends of the second partition plate 420 and the third partition plate 430.
[0057] The first partition plate 410, the second partition plate 420, and the third partition plate 430 may have the same length along the reference direction D (i.e., the same longitudinal length), and the first partition plate 410 may have a greater range than the second partition plate 420 and the third partition plate 430. That is, the lateral length of the first partition plate 410 may be formed to be greater than the lateral length of the second partition plate 420 and the third partition plate 430.
[0058] The lateral ends of the first partition plate 410 may contact the inner surface of the side plate 110, or may be spaced apart from the inner surface of the side plate 110. Similarly, the lateral ends of the second partition plate 420 and the third partition plate 430 may contact the inner surface of the side plate 110, or may be spaced apart from the inner surface of the side plate 110.
[0059] According to the illustrated embodiment, the chamber partition 400 can be configured to divide the chamber 130 in the first portion 110a into four equal parts. For example, the first partition plate 410 can be connected to overlap with the central axis CA of the main body 100 (or side plate 110), the second partition plate 420 can be connected to be perpendicular to the first surface 411 of the first partition plate 410, and the third partition plate 430 can be connected to be perpendicular to the second surface of the first partition plate 410. Here, the central axis CA refers to the axis parallel to the reference direction D and passing through the center of the side plate 110. That is, the first partition plate 410 divides the chamber 130 into two parts, and the second partition plate 420 and the third partition plate 430 further divide the two partitioned spaces into two parts respectively.
[0060] However, this is just an example; the chamber partition 400 can divide the chamber 130 into four spaces, at least some of which can have different volumes or dimensions. Furthermore, the number of partitions in the chamber 130 is not limited to four, and various variations are possible. See below for further details. Figure 6 and Figure 7 A detailed description is given of an embodiment in which the chamber 130 is divided into different numbers of spaces.
[0061] The chamber partition 400 can be configured such that the ends of the plurality of partition plates 410, 420, and 430 on the side opposite to the reference direction D do not extend beyond the first portion 110a of the side plate 110. Furthermore, the chamber partition 400 can also be configured such that the ends of the plurality of partition plates 410, 420, and 430 on the side opposite to the reference direction D do not extend beyond the ends of the distribution holes 111 on the side opposite to the reference direction D. Here, the ends of the plurality of distribution holes 111 on the side opposite to the reference direction D can be referred to as the ends of the distribution hole array 112 on the side opposite to the reference direction D, i.e. Figure 3 The uppermost part of the burner 10. That is, in a cross section taken along the reference direction D of the burner 10, the chamber partition 400 may not be positioned above the plurality of distribution holes 111 and / or pads 300.
[0062] The chamber partition 400 can be formed such that the ends of the plurality of partition plates 410, 420, 430 on the side opposite to the reference direction D are located within a reference interval G from the ends of the plurality of distribution holes 111 on the side opposite to the reference direction D.
[0063] The structural design takes into account that the flow in the chamber 130 may become unstable when the height of the multiple partition plates 410, 420, 430 exceeds or is excessively lower than the height of the multiple distribution holes 111.
[0064] Thus, by dividing the chamber 130 into multiple spaces through the chamber partition 400, noise generated during combustion can be reduced. Specifically, unlike the burner 10 according to this disclosure, when the chamber 130 is not divided into multiple spaces, the flow of the premixed gas exhibits turbulent characteristics, which may cause unstable noise caused by internal flow and flame, with the side plate 110 as the boundary, during the formation of the combustion flame. According to the embodiments of this disclosure, by providing the chamber partition 400 that divides the chamber 130 into multiple spaces, the flow of the premixed gas in the chamber 130 can be stabilized into laminar flow, thereby reducing noise generated during flame formation.
[0065] Figure 5 This is a cross-sectional view of a burner according to an embodiment of the present disclosure.
[0066] Figure 5 It shows the relationship with Figure 3 The burner 10 shown is different from the burner 10', wherein the height of the chamber partition 400 and the height of the plurality of distribution holes 111 coincide with each other, and furthermore, these heights are formed to coincide with the height of the pad 300.
[0067] Figure 5 The burner 10' can be with Figures 1 to 4 The burner 10 is basically the same as the original, except for a modified portion that changes the height of the chamber partition 400 and the multiple distribution holes 111. The repeated descriptions above are omitted hereafter; the following description focuses on the modified portions.
[0068] Reference Figure 5 The side plate 110 can be formed such that the ends of the plurality of distribution holes 111 on the side opposite to the reference direction D coincide with the ends of the pad portion 300 on the side opposite to the reference direction D. For example, in a cross-section of the burner 10' taken along the reference direction D, the ends of each of the plurality of distribution holes 111 and the pad portion 300 on the side opposite to the reference direction D can be located on an imaginary line L perpendicular to the reference direction D. Here, the imaginary line L can be the boundary between the first portion 110a and the second portion 110b of the side plate 110. That is, in Figure 5 In the burner 10', the uppermost end of the plurality of distribution holes 111 may be the part where the first part 110a ends and the second part 110b begins.
[0069] The chamber partition 400 can be configured such that the ends of the plurality of partition plates 410, 420, 430 on the side opposite to the reference direction D coincide with the ends of the plurality of distribution holes 111 on the side opposite to the reference direction D. For example, in 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 side opposite to the reference direction D relative to the chamber partition 400, but may be covered by the plurality of partition plates 410, 420, 430.
[0070] according to Figure 5 In the illustrated embodiment, the ends of the plurality of partition plates 410, 420, 430, the plurality of distribution holes 111, and the pad portion 300 on the side opposite to the reference direction D can overlap each other. That is, in a cross-section of the burner 10' taken along the reference direction D, the ends of the plurality of partition plates 410, 420, 430, the plurality of distribution holes 111, and the pad portion 300 on the side opposite to the reference direction D can coincide with the imaginary line L.
[0071] In this way, by optimizing the height of the chamber partition 400 to coincide with the upper end of the plurality of distribution holes 111, the noise reduction effect can be improved.
[0072] Figure 6 This is a view illustrating a first variant example of a chamber partition according to an embodiment of the present disclosure. Figure 7 This is a view illustrating a second variant example of a chamber partition according to an embodiment of the present disclosure.
[0073] Figure 6 and Figure 7 This is a view showing a variant embodiment, in which... Figures 1 to 4 Unlike the burner 10, the chamber partition 400 is configured to divide the chamber 130 of the side plate 110 into six spaces and eight spaces. The repeated descriptions above are omitted hereafter; the following description focuses on the variant.
[0074] First, refer to Figure 6 The chamber partition 400 can be configured to divide the chamber 130 into six spaces.
[0075] The chamber partition 400 may include a first partition plate 410, a second partition plate 420 and a fourth partition plate 440, as well as a third partition plate 430 and a fifth partition plate 450. The second partition plate 420 and the fourth partition plate 440 are connected to one surface of the first partition plate 410 and divide the space on one side of the first partition plate 410 into three spaces. The third partition plate 430 and the fifth partition plate 450 are connected to the opposite surface of the first partition plate 410 and divide the space on the opposite side of the first partition plate 410 into three spaces.
[0076] A surface of the first partition plate 410 connected to the second partition plate 420 and the fourth partition plate 440 and the opposing surface of the first partition plate 410 connected to the third partition plate 430 and the fifth partition plate 450 may face opposite sides.

The third partition 430 and the fifth partition 450 can be connected and fixed to the opposite surface of the first partition 410 (e.g., the surface facing the upper left side with reference to the figure) and the cover plate 120 of the main body 100, respectively.
[0078] As illustrated, the chamber partition 400 can divide the chamber 130 into six parts along the circumferential direction. However, it is not necessarily limited to a uniform division; the chamber partition 400 can divide the chamber 130 into six spaces, wherein at least some of the volumes or dimensions of the six spaces can be unevenly divided from each other.
[0079] Next, refer to Figure 7 The chamber partition 400 can be configured to divide the chamber 130 into eight spaces. Figure 6 In contrast, the chamber partition 400 may further include a sixth partition 460 connected to one surface of the first partition 410 and a seventh partition 470 connected to the opposite surface of the first partition 410.
[0080] The sixth partition plate 460 can be connected to one surface of the first partition plate 410 together with the second partition plate 420 and the fourth partition plate 440, and can divide the space on one side of the first partition plate 410 into four spaces. The seventh partition plate 470 can be connected to the opposite surface of the first partition plate 410 together with the third partition plate 430 and the fifth partition plate 450, and can divide the space on the opposite side of the first partition plate 410 into four spaces.
[0081] As illustrated, the chamber partition 400 can divide the chamber 130 into eight parts along the circumferential direction. However, it is not necessarily limited to uniform division; the chamber partition 400 can divide the chamber 130 into eight spaces, wherein at least some of the volumes or dimensions of the eight spaces can be unevenly divided from each other.
[0082] at the same time, Figure 2 , Figure 6 and Figure 7The illustration shows the chamber partition 400 dividing the chamber 130 into four, six, and eight spaces, respectively. However, this is exemplary, and the chamber partition 400 according to this disclosure is not limited to the form in which the chamber 130 is divided into an even number of spaces. For example, the chamber partition 400 can be configured to divide the chamber 130 into an odd number of spaces, such as three, five, or seven spaces, and the number, shape, and connection structure of the plurality of partitions can be modified accordingly.
[0083] Figure 8 This is a view illustrating a third variant example of a chamber partition according to an embodiment of the present disclosure.
[0084] Figure 8 This is a view showing a variant example, wherein one or more through holes 480 are formed in at least one of the partition plates 410, 420, 430 of the chamber partition 400.
[0085] Figure 8 This shows that through-hole 480 is formed in Figures 1 to 4 The embodiment shown is of the chamber partition 400, but this is for ease of description. Figure 8 The variant embodiments can be applied in the same manner as described above. Figure 6 and Figure 7 The chamber partition 400.
[0086] Reference Figure 8 The chamber partition 400 may also be configured such that one or more through holes 480 are formed in at least one of the plurality of partition plates 410, 420, 430. For example, according to the example shown, two through holes 480 may be formed in the first partition plate 410, and one through hole 480 may be formed in each of the second partition plate 420 and the third partition plate 430.
[0087] However, this is merely by way of example, and the number of partitions 410, 420 and 430 in which through holes 480 are formed can be modified differently, and the size, position, shape and / or number of through holes 480 formed in a particular partition are not particularly limited and can also be changed differently.
[0088] Since the through-hole 480 is formed in the multiple partition plates 410, 420 and 430, the chamber 130 is separated and divided by the multiple partition plates 410, 420 and 430, which reduces combustion noise and can also avoid spatial noise that may occur due to the multiple separated spaces.
