CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the priority benefits of China application serial no. 202510089119.9, filed on Jan. 21, 2025, and China application serial no. 202510469555.9, filed on Apr. 15, 2025. The entirety of the above-mentioned patent applications is hereby incorporated by reference herein and made a part of this specification.TECHNICAL FIELD

[0002] The present invention relates to the technical field of heaters, and more particularly to a gas heater.BACKGROUND

[0003] A gas heater is a device that releases heat by burning fuel gas to generate flames. This device requires a combustion chamber and a heat conduct and heat dissipation part. The combustion chamber and the heat conduct and heat dissipation part need to be connected together, usually using aluminum alloy support for fixed connection.

[0004] At present, the finished aluminum alloy support parts on the market need to undergo secondary processing to meet the installation requirements of gas heaters, which waste a lot of time. They can also be produced by designing the molds with suitable shapes, but the cost of the mold is high. Therefore, it is considered whether the cost problem can be solved through sheet metal bending technology. However, after the sheet metal is bent, there is a certain internal stress at the bend, and this internal stress will produce a phenomenon of recovery deformation, which will cause problems in subsequent installation and use. For example, when one end of the bent sheet metal is fixed to the gas heater, the other side cannot fit. Even if the other side is fixed to the gas heater with some tools, the internal stress at the bend cannot be released for a long time, and cracks will appear at the bend, which will have a significant impact on the user experience.

[0005] Therefore, it is necessary to propose a gas heater to solve the problems of high production costs and large internal stress after the support parts are installed.SUMMARY

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a gas heater which reduces production costs, reduces stress concentration, improves stability, and has high installation efficiency.

[0007] In one embodiment, a gas heater is disclosed, and comprises a gas chamber, a heat conducting part and a plurality of groups of support members.

[0008] The gas chamber includes a gas chamber bottom plate, a plurality of shielding plates, a gas chamber top plate and a combustion device. The gas chamber top plate and the gas chamber bottom plate is arranged vertically along the upright direction of the gas heater. The upper end of the shielding plate is connected to the gas chamber top plate. The lower end of the shielding plate is connected to the gas chamber bottom plate. The combustion device has a fire outlet.

[0009] The heat conducting part includes a glass tube and a fixing frame. The glass tube is arranged to cover directly above the fire outlet of the combustion device. The fixing frame is installed on the upper end side of the glass tube.

[0010] The support member is divided into an upper support portion and a lower support portion along the upright direction of the gas heater. The upper support portion includes a first support sheet, an upper main body and a second support sheet. The upper main body has a first concave and a first concave opening. The first concave has two opposite first end edges. The two first end edges define the first concave opening. The first concave protrudes toward the outside of the gas heater. The first concave opening faces the heat conducting part. The first support sheet is connected to one of the first end edges. The second support sheet is connected to the other of the first end edges. The first support sheet and the second support sheet are connected to the gas chamber top plate and the fixing frame. The first support sheet, the upper main body and the second support sheet are integrally formed by bending a metal plate. The lower support portion includes a third support sheet, a lower main body and a fourth support sheet. The lower main body has a second concave and a second concave opening. The second concave has two opposite second end edges. The two second end edges define the second concave opening. The second concave protrudes toward the outside of the gas heater. The second concave opening faces the gas chamber. The third support sheet is connected to one of the second end edges, and the fourth support sheet is connected to the other of the second end edges. The third support sheet and the fourth support sheet are connected to the gas chamber top plate and the gas chamber bottom plate. The third support sheet, the lower main body and the fourth support sheet are integrally formed by bending a metal plate.

[0011] By adopting the above technical solution, the upper support portion and the lower support portion are processed by the one-piece forming technology of bending metal plates. Compared with aluminum alloy casting, the use of bending metal plates has low production costs and high production efficiency. The stress at the bending point of the upper support portion is evenly distributed through the bending points set between the first support sheet, the upper main body and the second support sheet, thereby reducing the concentration of stress. The shape of the lower support portion is similar to that of the upper support portion and has the effect of reducing stress concentration.

[0012] In one embodiment, the gas heater is placed perpendicularly to the ground along the upright direction. The support member has an axial direction following the upright direction. A modeling angle is formed between the axial direction and a vertical line of the ground, and a shaping angle is formed between a surface extension direction of the supporting shaping plate and a surface extension direction of the concave shaping plate. The modeling angle and the shaping angle are complementary angles. The upper main body has a length direction along the axial direction, and the length of the upper main body is less than 1409 mm. The thickness of the male docking plate is 0.9 mm to 1.1 mm. The thickness of the shaping piece is 1 mm to 2 mm. The total thickness of the upper main body, the male docking plate and the concave shaping plate bonded together is 3 mm to 4 mm.

[0013] By adopting the above technical solution, a thicker shaping piece is used. On the one hand, the thickness of the shaping piece affects the attached area between the two ends of the shaping piece and the first side panel bonding sheet and the second side panel bonding sheet. The larger the attached area, the higher the stability. On the other hand, the thickness of the shaping piece also affects the bearing capacity of the upper part of the gas heater. Because the gravity of the upper part of the gas heater is evenly distributed to the gas chamber top plate by the shaping piece, only the shaping piece with sufficient thickness can stably support the upper part of the gas heater.BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to FIG. 1 to FIG. 9, the embodiments of the present invention provide the following technical solutions:

[0029] In the first embodiment, referring to FIG. 1, a gas heater comprises a gas chamber 1, a heat conducting part 2 and a plurality of support members 3. The gas chamber 1 is used to place and connect a gas tank, and fuel gas is provided through the gas tank. The heat conducting part 2 is used to conduct heat energy generated by combustion in the gas chamber 1. The support members 3 are used to bear the weight of the heater as a whole.

[0030] The gas chamber 1 includes a gas chamber bottom plate 11, a plurality of shielding plates 12, a gas chamber top plate 14 and a combustion device 15. The gas chamber top plate 14 and the gas chamber bottom plate 11 are arranged vertically along the upright direction of the gas heater. The upper end of the shielding plate 12 is connected to the gas chamber top plate 14, and the lower end of the shielding plate 12 is connected to the gas chamber bottom plate 11. The combustion device 15 has a fire outlet. The gas chamber 1 further comprises a panel 13. The shielding plate 12 and the panel 13 are arranged around the gas chamber top plate 14 and the gas chamber bottom plate 11. The combustion device 15 is placed below the gas chamber top plate 14.

[0031] The heat conducting part 2 includes a glass tube 21, an infrared generator 22, a fixing frame 23 and a top cover 24. The glass tube 21 is arranged to cover directly above the fire outlet of the combustion device 15. The fixing frame 23 is installed on the upper end side of the glass tube 21. The infrared generator 22 is installed on the other end side of the glass tube 21. A top cover 24 is arranged above the fixing frame 23, and the top cover 24 is fixedly connected to the fixing frame 23.

[0032] The support of the heater is mainly achieved by the support member 3. The original processing technology is through aluminum alloy casting. The shape of this aluminum alloy support member 3 is a special-shaped structure. The processing in this way requires a separate mold, and the cost of the mold is high. In addition, during the product logistics packaging process, the upper support portion 31 and the lower support portion 32 need to be packaged separately, which wastes packaging time and increases the packaging cost.

[0033] Referring to FIG. 3, the support member 3 is divided into an upper support portion 31 and a lower support portion 32 along the upright direction of the gas heater. The upper support portion 31 includes a first support sheet 311, an upper main body 312, and a second support sheet 313. The first support sheet 311, the upper main body 312, and the second support sheet 313 are integrally formed by bending a metal plate. The lower support portion 32 includes a third support sheet 321, a lower main body 322, and a fourth support sheet 323. The third support sheet 321, the lower main body 322, and the fourth support sheet 323 are integrally formed by bending a metal plate. The upper support portion 31 and the lower support portion 32 are processed by the bending metal plate integral forming technology. Compared with aluminum alloy casting, the use of bending metal plates has low production costs and high production efficiency.

[0034] Referring to FIG. 4 to FIG. 6, the upper main body 312 has a first concave 3121 and a first concave opening 3122. The first concave 3121 has two opposite first end edges 31211. The two first end edges 31211 define the first concave opening 3122.

[0035] The first concave 3121 protrudes toward the outside of the gas heater. The first concave opening 3122 faces the heat conducting part 2. The first support sheet 311 is connected to one of the first end edges 31211, and the second support sheet 313 is connected to the other of the first end edges 31211. The first support sheet 311 and the second support sheet 313 are connected to the gas chamber top plate 14 and the fixing frame 23.

[0036] The lower main body 322 has a second concave 3221 and a second concave opening 3222. The second concave 3221 has two opposite second end edges 32211. The two second end edges 32211 define the second concave opening 3222. The second concave 3221 protrudes toward the outside of the gas heater. The second concave opening 3222 faces the gas chamber 1. The third support sheet 321 is connected to one of the second end edges 32211, and the fourth support sheet 323 is connected to the other of the second end edges 32211. The third support sheet 321 and the fourth support sheet 323 are connected to the gas chamber top plate 14 and the gas chamber bottom plate 11.

[0037] The attached positions of the support member 3 with the gas chamber bottom plate 11, the gas chamber top plate 14 and the fixing frame 23 are provided with mounting bolt holes 4. When the first support sheet 311 and the second support sheet 313 are fixed to the gas chamber top plate 14 and the fixing frame 23 by passing bolts through the mounting bolt holes 4, the metal plates that have been restored and deformed are locked by the bolts, so that the first support sheet 311 and the second support sheet 313 are in contact with the gas chamber top plate 14 and the fixing frame 23. At this time, stress exists at the bent positions thereof. Through the multiple bending points set between the first support sheet 311, the upper main body 312 and the second support sheet 313, the stress can be evenly distributed through the multiple bending points, thereby reducing the concentration of stress. The lower support portion 32 is similar in shape to the upper support portion 31 and has the effect of reducing stress concentration.

[0038] Referring to FIG. 2 to FIG. 7, the shielding plate 12 is located between two adjacent lower support portions 32 and connects the two adjacent lower support portions 32. The lower support portion 32 on one side is connected to the shielding plate 12 through the third support sheet 321, and the lower support portion 32 on the other side is connected to the shielding plate 12 through the fourth support sheet 323. The shielding plate 12 and the third support sheets 321, the lower main bodies 322 and the fourth support sheet 323 of the two adjacent lower support portions 32 are integrally formed by bending a metal plate. The shielding plate 12 and the two lower support portions 32 are integrally formed by bending the metal plate, which has high production and installation efficiency, and the connection strength between them is high, thereby improving the stability of the lower part of the heater. At the same time, this structure can reduce packaging costs during logistics.

[0039] Referring to FIG. 7, the lower support portion 32 has a second reinforcement member 324, which has a second connecting rib 3242, a third fitting surface 3241 and a fourth fitting surface 3243. The second connecting rib 3242 connects the third fitting surface 3241 and the fourth fitting surface 3243, and the second connecting rib 3242, the third fitting surface 3241 and the fourth fitting surface 3243 are integrally formed by bending a metal plate. The second reinforcement member 324 is placed below gas chamber bottom plate 11, and the third fitting surface 3241 and the fourth fitting surface 3243 are respectively attached to the third support sheet 321 and the fourth support sheet 323. The second connecting rib 3242 spans the second concave opening 3222. The second reinforcement member 324 is used to improve the strength of the leg of the heater and make the bottom more solid.

[0040] Referring to FIG. 8, the upper support portion 31 is connected to the lower support portion 32 via a plug-in structure. The upper support portion 31 further comprises a male docking plate 315 and a shaping piece 316. The male docking plate 315 is connected to the upper main body 312. The outer surface of the connection between the male docking plate 315 and the upper main body 312 forms a step structure. The shaping piece 316 is attached to the upper surface of the gas chamber top plate 14.

[0041] An edge of the shaping piece 316 is connected to the inner surface of the connection between the male docking plate 315 and the upper main body 312. The male docking plate 315 is integrally formed with the first support sheet 311, the upper main body 312 and the second support sheet 313 by bending a metal plate.

[0042] A shaping screw hole 3161 is provided at the attached position between the shaping piece 316 and the gas chamber top plate 14, and the shaping screw hole 3161 is used to insert a bolt to fix the shaping piece 316 to the gas chamber top plate 14. The male docking plate 315 is integrally formed with the first support sheet 311, the upper main body 312 and the second support sheet 313 by bending a metal plate. The male docking plate 315 and the female docking groove are docked and installed to improve the user's installation efficiency, and the shaping piece 316 is connected to the gas chamber top plate 14 to further improve the stability of the top of the heater.

[0043] Referring to FIG. 2, the lower support portion 32 has a connecting piece 325, which is disposed on the upper end side of the lower support portion 32 and encloses the upper end side of the lower support portion 32 to form the female docking groove. The male docking plate 315 is inserted into the female docking groove. The height of the lower main body 322 is about 878.2 mm, the overall thickness of the connecting piece 325 is 1 mm, and the length of the connecting piece 325 is about 50 mm. The approximate ratio of the height of the lower main body 322 to the length of the connecting piece 325 is 1:18. The longer the length of the connecting piece 325, the more stable the upper end of the lower main body 322.

[0044] Referring to FIG. 5, the gas chamber bottom plate 11 has a plurality of bottom plate edge pieces 111. The intersection of the two adjacent bottom plate edge pieces 111 forms a bottom plate corner 12. The bottom plate corner 12 is placed inside the second concave 3221 through the second concave opening 3222. The fixing frame 23 has a plurality of fixing frame edge pieces 231. The intersection of the two adjacent fixing frame edge pieces 231 forms a fixing frame corner 232. The fixing frame corner 232 is placed inside the first concave 3121 through the first concave opening 3122.

[0045] The gas chamber top plate 14 has a plurality of top plate edge pieces 141. The intersection of the two adjacent top plate edge pieces 141 forms a top plate corner 142. The top plate corner 142 is placed inside the second concave 3221 through the second concave opening 3222. The top plate corner 142 is inserted into the space enclosed by the inner surface of the male docking plate 315. The bottom plate corner 112, the top plate corner 142 and the fixing frame corner 232 are in contact with the first end edge 31211 or the second end edge 32211. By setting two contact points for each corner, the force is more uniform, and the heater is more stable as a whole.

[0046] In the second embodiment, to enhance the structural stability of the first concave 3121 in Embodiment 1, referring to FIG. 8, the upper support portion 31 has a first reinforcement member 314. The first reinforcement member 314 has a first connecting rib 3142, a first fitting surface 3141 and a second fitting surface 3143. The first connecting rib 3142 is connected to the first fitting surface 3141 and the second fitting surface 3143. The first connecting rib 3142, the first fitting surface 3141 and the second fitting surface 3143 are integrally formed by bending a metal plate. The first fitting surface 3141 and the second fitting surface 3143 are respectively attached to the first support sheet 311 and the second support sheet 312. The first connecting rib 3142 spans the first concave opening 3122.

[0047] The upper support portion 31 is fixed from the inner side of the upper main body 312 by the first reinforcement member 314 to prevent it from shaking when pushed by external force, thereby improving the stability of the upper components of the heater.

[0048] In the third embodiment, according to the description of the male docking plate 315 and the shaping piece 316 of the upper support portion 31 in the first embodiment, referring to FIG. 9 to FIG. 11, the structure may also be:

[0049] The male docking plate 515 comprises a concave bottom bonding sheet 5151, a first side panel bonding sheet 5152 and a second side panel bonding sheet 5153. The concave bottom bonding sheet 5151 connects the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 The concave bottom bonding sheet 5151, the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 are integrally formed by bending a metal plate. The male docking plate 515 is placed on the inner side of the first concave 3121.

[0050] The upper end of the male docking plate 515 is attached to the lower end of the upper main body 312. The lower end of the male docking plate 515 exceeds the upper main body 312 and is plugged into the female docking groove. The first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 are not arranged to exceed the first end edge 31211. When the gas heater is shaken or pushed by an external force, the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 are bonded to the two end sides of the first concave 3121, so that the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 and the first concave 3121 can support each other, reduce the shaking amplitude, and improve stability.

[0051] The shaping piece 516 comprises a concave shaping plate 5161 and a supporting shaping plate 5162. The concave shaping plate 5161 is attached to the concave bottom bonding sheet 5151. Two end sides of the concave shaping plate 5161 are respectively attached to the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153. Two end sides of the supporting shaping plate 5162 are respectively connected to the first support sheet 311 and the second support sheet 313. The lower surface of the supporting shaping plate 5162 is not arranged to exceed the lower end surface of the first support sheet 311 and the lower end surface of the second support sheet 313, for example, the three are on the same plane. The concave shaping plate 5161 and the supporting shaping plate 5162 are integrally formed by bending a metal plate.

[0052] The shaping piece 516 is connected with the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 to further limit the internal shape of the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 and the first concave 3121, so that the shaking amplitude can be further limited when the gas heater is shaken or pushed by external force, thereby improving stability.

[0053] The gas heater is placed perpendicular to the ground along the upright direction, and the support member 3 has an axial direction following the upright direction. A modeling angle is formed between the axial direction and a vertical line of the ground, and a shaping angle is formed between a surface extension direction of the supporting shaping plate 5162 and a surface extension direction of the concave shaping plate 5161. The modeling angle and the shaping angle are complementary angles.

[0054] The upper main body 312 has a length direction along the axial direction, the length of the upper main body 312 is less than 1409 mm, and the preferred length is 1152 mm to 1409 mm. The thickness of the male docking plate 515 is 0.9 mm to 1.1 mm, and the thickness of the shaping piece 516 is 1 mm to 2 mm. The total thickness of the upper main body 312, the male docking plate 515 and the concave shaping plate 5161 bonded together is 3 mm to 4 mm.

[0055] The thickness of the shaping piece 516 is preferably 1.5 mm. On the one hand, the thickness of the shaping piece 516 affects the attached area between the two ends of the shaping piece 516 and the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153. The larger the bonding area, the higher the stability. On the other hand, the thickness of the shaping piece 516 also affects the bearing capacity of the upper part of the gas heater. Because the gravity of the upper part of the gas heater is evenly distributed to the gas chamber top plate 14 by the shaping piece 516, only a shaping piece 516 with sufficient thickness can stably support the upper part of the gas heater.

[0056] The aforementioned structure of the components installed on the supporting fulcrum and the thickness of each component not only facilitate assembly and secure combination, but also after the components are assembled, the overall thickness of the supporting fulcrum can firmly support the length of the upper main body 312 below 1409 mm, thereby preventing the gas heater from twisting and shaking.

[0057] In the fourth embodiment, the shape of the fixing frame corner 232 matches the shape of the first concave opening 3122, and the shape of the bottom plate corner 112, the shape of the top plate corner 142, and the shape of the second concave opening 3222 match. The overall stability of the heater is further improved through a larger contact area.

It is not intended to be exhaustive or to limit the disclosure to the precise form or to exemplary embodiments disclosed. Accordingly, the foregoing description should be regarded as illustrative rather than restrictive. Obviously, many modifications and variations will be apparent to practitioners skilled in this art.

Examples

first embodiment

[0029]In the first embodiment, referring to FIG. 1, a gas heater comprises a gas chamber 1, a heat conducting part 2 and a plurality of support members 3. The gas chamber 1 is used to place and connect a gas tank, and fuel gas is provided through the gas tank. The heat conducting part 2 is used to conduct heat energy generated by combustion in the gas chamber 1. The support members 3 are used to bear the weight of the heater as a whole.

[0030]The gas chamber 1 includes a gas chamber bottom plate 11, a plurality of shielding plates 12, a gas chamber top plate 14 and a combustion device 15.

[0002] The present invention relates to the technical field of heaters, and more particularly to a gas heater.BACKGROUND

[0003] A gas heater is a device that releases heat by burning fuel gas to generate flames. This device requires a combustion chamber and a heat conduct and heat dissipation part. The combustion chamber and the heat conduct and heat dissipation part need to be connected together, usually using aluminum alloy support for fixed connection.

[0004] At present, the finished aluminum alloy support parts on the market need to undergo secondary processing to meet the installation requirements of gas heaters, which waste a lot of time. They can also be produced by designing the molds with suitable shapes, but the cost of the mold is high. Therefore, it is considered whether the cost problem can be solved through sheet metal bending technology. However, after the sheet metal is bent, there is a certain internal stress at the bend, and this internal stress will produce a phenomenon of recovery deformation, which will cause problems in subsequent installation and use. For example, when one end of the bent sheet metal is fixed to the gas heater, the other side cannot fit. Even if the other side is fixed to the gas heater with some tools, the internal stress at the bend cannot be released for a long time, and cracks will appear at the bend, which will have a significant impact on the user experience.

[0005] Therefore, it is necessary to propose a gas heater to solve the problems of high production costs and large internal stress after the support parts are installed.SUMMARY

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a gas heater which reduces production costs, reduces stress concentration, improves stability, and has high installation efficiency.

[0007] In one embodiment, a gas heater is disclosed, and comprises a gas chamber, a heat conducting part and a plurality of groups of support members.

[0008] The gas chamber includes a gas chamber bottom plate, a plurality of shielding plates, a gas chamber top plate and a combustion device. The gas chamber top plate and the gas chamber bottom plate is arranged vertically along the upright direction of the gas heater. The upper end of the shielding plate is connected to the gas chamber top plate. The lower end of the shielding plate is connected to the gas chamber bottom plate. The combustion device has a fire outlet.

[0009] The heat conducting part includes a glass tube and a fixing frame. The glass tube is arranged to cover directly above the fire outlet of the combustion device. The fixing frame is installed on the upper end side of the glass tube.

[0010] The support member is divided into an upper support portion and a lower support portion along the upright direction of the gas heater. The upper support portion includes a first support sheet, an upper main body and a second support sheet. The upper main body has a first concave and a first concave opening. The first concave has two opposite first end edges. The two first end edges define the first concave opening. The first concave protrudes toward the outside of the gas heater. The first concave opening faces the heat conducting part. The first support sheet is connected to one of the first end edges. The second support sheet is connected to the other of the first end edges. The first support sheet and the second support sheet are connected to the gas chamber top plate and the fixing frame. The first support sheet, the upper main body and the second support sheet are integrally formed by bending a metal plate. The lower support portion includes a third support sheet, a lower main body and a fourth support sheet. The lower main body has a second concave and a second concave opening. The second concave has two opposite second end edges. The two second end edges define the second concave opening. The second concave protrudes toward the outside of the gas heater. The second concave opening faces the gas chamber. The third support sheet is connected to one of the second end edges, and the fourth support sheet is connected to the other of the second end edges. The third support sheet and the fourth support sheet are connected to the gas chamber top plate and the gas chamber bottom plate. The third support sheet, the lower main body and the fourth support sheet are integrally formed by bending a metal plate.

[0011] By adopting the above technical solution, the upper support portion and the lower support portion are processed by the one-piece forming technology of bending metal plates. Compared with aluminum alloy casting, the use of bending metal plates has low production costs and high production efficiency. The stress at the bending point of the upper support portion is evenly distributed through the bending points set between the first support sheet, the upper main body and the second support sheet, thereby reducing the concentration of stress. The shape of the lower support portion is similar to that of the upper support portion and has the effect of reducing stress concentration.

[0012] In one embodiment, the gas heater is placed perpendicularly to the ground along the upright direction. The support member has an axial direction following the upright direction. A modeling angle is formed between the axial direction and a vertical line of the ground, and a shaping angle is formed between a surface extension direction of the supporting shaping plate and a surface extension direction of the concave shaping plate. The modeling angle and the shaping angle are complementary angles. The upper main body has a length direction along the axial direction, and the length of the upper main body is less than 1409 mm. The thickness of the male docking plate is 0.9 mm to 1.1 mm. The thickness of the shaping piece is 1 mm to 2 mm. The total thickness of the upper main body, the male docking plate and the concave shaping plate bonded together is 3 mm to 4 mm.

[0013] By adopting the above technical solution, a thicker shaping piece is used. On the one hand, the thickness of the shaping piece affects the attached area between the two ends of the shaping piece and the first side panel bonding sheet and the second side panel bonding sheet. The larger the attached area, the higher the stability. On the other hand, the thickness of the shaping piece also affects the bearing capacity of the upper part of the gas heater. Because the gravity of the upper part of the gas heater is evenly distributed to the gas chamber top plate by the shaping piece, only the shaping piece with sufficient thickness can stably support the upper part of the gas heater.BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to FIG. 1 to FIG. 9, the embodiments of the present invention provide the following technical solutions:

[0029] In the first embodiment, referring to FIG. 1, a gas heater comprises a gas chamber 1, a heat conducting part 2 and a plurality of support members 3. The gas chamber 1 is used to place and connect a gas tank, and fuel gas is provided through the gas tank. The heat conducting part 2 is used to conduct heat energy generated by combustion in the gas chamber 1. The support members 3 are used to bear the weight of the heater as a whole.

[0030] The gas chamber 1 includes a gas chamber bottom plate 11, a plurality of shielding plates 12, a gas chamber top plate 14 and a combustion device 15. The gas chamber top plate 14 and the gas chamber bottom plate 11 are arranged vertically along the upright direction of the gas heater. The upper end of the shielding plate 12 is connected to the gas chamber top plate 14, and the lower end of the shielding plate 12 is connected to the gas chamber bottom plate 11. The combustion device 15 has a fire outlet. The gas chamber 1 further comprises a panel 13. The shielding plate 12 and the panel 13 are arranged around the gas chamber top plate 14 and the gas chamber bottom plate 11. The combustion device 15 is placed below the gas chamber top plate 14.

[0031] The heat conducting part 2 includes a glass tube 21, an infrared generator 22, a fixing frame 23 and a top cover 24. The glass tube 21 is arranged to cover directly above the fire outlet of the combustion device 15. The fixing frame 23 is installed on the upper end side of the glass tube 21. The infrared generator 22 is installed on the other end side of the glass tube 21. A top cover 24 is arranged above the fixing frame 23, and the top cover 24 is fixedly connected to the fixing frame 23.

[0032] The support of the heater is mainly achieved by the support member 3. The original processing technology is through aluminum alloy casting. The shape of this aluminum alloy support member 3 is a special-shaped structure. The processing in this way requires a separate mold, and the cost of the mold is high. In addition, during the product logistics packaging process, the upper support portion 31 and the lower support portion 32 need to be packaged separately, which wastes packaging time and increases the packaging cost.

[0033] Referring to FIG. 3, the support member 3 is divided into an upper support portion 31 and a lower support portion 32 along the upright direction of the gas heater. The upper support portion 31 includes a first support sheet 311, an upper main body 312, and a second support sheet 313. The first support sheet 311, the upper main body 312, and the second support sheet 313 are integrally formed by bending a metal plate. The lower support portion 32 includes a third support sheet 321, a lower main body 322, and a fourth support sheet 323. The third support sheet 321, the lower main body 322, and the fourth support sheet 323 are integrally formed by bending a metal plate. The upper support portion 31 and the lower support portion 32 are processed by the bending metal plate integral forming technology. Compared with aluminum alloy casting, the use of bending metal plates has low production costs and high production efficiency.

[0034] Referring to FIG. 4 to FIG. 6, the upper main body 312 has a first concave 3121 and a first concave opening 3122. The first concave 3121 has two opposite first end edges 31211. The two first end edges 31211 define the first concave opening 3122.

[0035] The first concave 3121 protrudes toward the outside of the gas heater. The first concave opening 3122 faces the heat conducting part 2. The first support sheet 311 is connected to one of the first end edges 31211, and the second support sheet 313 is connected to the other of the first end edges 31211. The first support sheet 311 and the second support sheet 313 are connected to the gas chamber top plate 14 and the fixing frame 23.

[0036] The lower main body 322 has a second concave 3221 and a second concave opening 3222. The second concave 3221 has two opposite second end edges 32211. The two second end edges 32211 define the second concave opening 3222. The second concave 3221 protrudes toward the outside of the gas heater. The second concave opening 3222 faces the gas chamber 1. The third support sheet 321 is connected to one of the second end edges 32211, and the fourth support sheet 323 is connected to the other of the second end edges 32211. The third support sheet 321 and the fourth support sheet 323 are connected to the gas chamber top plate 14 and the gas chamber bottom plate 11.

[0037] The attached positions of the support member 3 with the gas chamber bottom plate 11, the gas chamber top plate 14 and the fixing frame 23 are provided with mounting bolt holes 4. When the first support sheet 311 and the second support sheet 313 are fixed to the gas chamber top plate 14 and the fixing frame 23 by passing bolts through the mounting bolt holes 4, the metal plates that have been restored and deformed are locked by the bolts, so that the first support sheet 311 and the second support sheet 313 are in contact with the gas chamber top plate 14 and the fixing frame 23. At this time, stress exists at the bent positions thereof. Through the multiple bending points set between the first support sheet 311, the upper main body 312 and the second support sheet 313, the stress can be evenly distributed through the multiple bending points, thereby reducing the concentration of stress. The lower support portion 32 is similar in shape to the upper support portion 31 and has the effect of reducing stress concentration.

[0038] Referring to FIG. 2 to FIG. 7, the shielding plate 12 is located between two adjacent lower support portions 32 and connects the two adjacent lower support portions 32. The lower support portion 32 on one side is connected to the shielding plate 12 through the third support sheet 321, and the lower support portion 32 on the other side is connected to the shielding plate 12 through the fourth support sheet 323. The shielding plate 12 and the third support sheets 321, the lower main bodies 322 and the fourth support sheet 323 of the two adjacent lower support portions 32 are integrally formed by bending a metal plate. The shielding plate 12 and the two lower support portions 32 are integrally formed by bending the metal plate, which has high production and installation efficiency, and the connection strength between them is high, thereby improving the stability of the lower part of the heater. At the same time, this structure can reduce packaging costs during logistics.

[0039] Referring to FIG. 7, the lower support portion 32 has a second reinforcement member 324, which has a second connecting rib 3242, a third fitting surface 3241 and a fourth fitting surface 3243. The second connecting rib 3242 connects the third fitting surface 3241 and the fourth fitting surface 3243, and the second connecting rib 3242, the third fitting surface 3241 and the fourth fitting surface 3243 are integrally formed by bending a metal plate. The second reinforcement member 324 is placed below gas chamber bottom plate 11, and the third fitting surface 3241 and the fourth fitting surface 3243 are respectively attached to the third support sheet 321 and the fourth support sheet 323. The second connecting rib 3242 spans the second concave opening 3222. The second reinforcement member 324 is used to improve the strength of the leg of the heater and make the bottom more solid.

[0040] Referring to FIG. 8, the upper support portion 31 is connected to the lower support portion 32 via a plug-in structure. The upper support portion 31 further comprises a male docking plate 315 and a shaping piece 316. The male docking plate 315 is connected to the upper main body 312. The outer surface of the connection between the male docking plate 315 and the upper main body 312 forms a step structure. The shaping piece 316 is attached to the upper surface of the gas chamber top plate 14.

[0041] An edge of the shaping piece 316 is connected to the inner surface of the connection between the male docking plate 315 and the upper main body 312. The male docking plate 315 is integrally formed with the first support sheet 311, the upper main body 312 and the second support sheet 313 by bending a metal plate.

[0042] A shaping screw hole 3161 is provided at the attached position between the shaping piece 316 and the gas chamber top plate 14, and the shaping screw hole 3161 is used to insert a bolt to fix the shaping piece 316 to the gas chamber top plate 14. The male docking plate 315 is integrally formed with the first support sheet 311, the upper main body 312 and the second support sheet 313 by bending a metal plate. The male docking plate 315 and the female docking groove are docked and installed to improve the user's installation efficiency, and the shaping piece 316 is connected to the gas chamber top plate 14 to further improve the stability of the top of the heater.

[0043] Referring to FIG. 2, the lower support portion 32 has a connecting piece 325, which is disposed on the upper end side of the lower support portion 32 and encloses the upper end side of the lower support portion 32 to form the female docking groove. The male docking plate 315 is inserted into the female docking groove. The height of the lower main body 322 is about 878.2 mm, the overall thickness of the connecting piece 325 is 1 mm, and the length of the connecting piece 325 is about 50 mm. The approximate ratio of the height of the lower main body 322 to the length of the connecting piece 325 is 1:18. The longer the length of the connecting piece 325, the more stable the upper end of the lower main body 322.

[0044] Referring to FIG. 5, the gas chamber bottom plate 11 has a plurality of bottom plate edge pieces 111. The intersection of the two adjacent bottom plate edge pieces 111 forms a bottom plate corner 12. The bottom plate corner 12 is placed inside the second concave 3221 through the second concave opening 3222. The fixing frame 23 has a plurality of fixing frame edge pieces 231. The intersection of the two adjacent fixing frame edge pieces 231 forms a fixing frame corner 232. The fixing frame corner 232 is placed inside the first concave 3121 through the first concave opening 3122.

[0045] The gas chamber top plate 14 has a plurality of top plate edge pieces 141. The intersection of the two adjacent top plate edge pieces 141 forms a top plate corner 142. The top plate corner 142 is placed inside the second concave 3221 through the second concave opening 3222. The top plate corner 142 is inserted into the space enclosed by the inner surface of the male docking plate 315. The bottom plate corner 112, the top plate corner 142 and the fixing frame corner 232 are in contact with the first end edge 31211 or the second end edge 32211. By setting two contact points for each corner, the force is more uniform, and the heater is more stable as a whole.

[0046] In the second embodiment, to enhance the structural stability of the first concave 3121 in Embodiment 1, referring to FIG. 8, the upper support portion 31 has a first reinforcement member 314. The first reinforcement member 314 has a first connecting rib 3142, a first fitting surface 3141 and a second fitting surface 3143. The first connecting rib 3142 is connected to the first fitting surface 3141 and the second fitting surface 3143. The first connecting rib 3142, the first fitting surface 3141 and the second fitting surface 3143 are integrally formed by bending a metal plate. The first fitting surface 3141 and the second fitting surface 3143 are respectively attached to the first support sheet 311 and the second support sheet 312. The first connecting rib 3142 spans the first concave opening 3122.

[0047] The upper support portion 31 is fixed from the inner side of the upper main body 312 by the first reinforcement member 314 to prevent it from shaking when pushed by external force, thereby improving the stability of the upper components of the heater.

[0048] In the third embodiment, according to the description of the male docking plate 315 and the shaping piece 316 of the upper support portion 31 in the first embodiment, referring to FIG. 9 to FIG. 11, the structure may also be:

[0049] The male docking plate 515 comprises a concave bottom bonding sheet 5151, a first side panel bonding sheet 5152 and a second side panel bonding sheet 5153. The concave bottom bonding sheet 5151 connects the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 The concave bottom bonding sheet 5151, the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 are integrally formed by bending a metal plate. The male docking plate 515 is placed on the inner side of the first concave 3121.

[0050] The upper end of the male docking plate 515 is attached to the lower end of the upper main body 312. The lower end of the male docking plate 515 exceeds the upper main body 312 and is plugged into the female docking groove. The first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 are not arranged to exceed the first end edge 31211. When the gas heater is shaken or pushed by an external force, the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 are bonded to the two end sides of the first concave 3121, so that the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 and the first concave 3121 can support each other, reduce the shaking amplitude, and improve stability.

[0051] The shaping piece 516 comprises a concave shaping plate 5161 and a supporting shaping plate 5162. The concave shaping plate 5161 is attached to the concave bottom bonding sheet 5151. Two end sides of the concave shaping plate 5161 are respectively attached to the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153. Two end sides of the supporting shaping plate 5162 are respectively connected to the first support sheet 311 and the second support sheet 313. The lower surface of the supporting shaping plate 5162 is not arranged to exceed the lower end surface of the first support sheet 311 and the lower end surface of the second support sheet 313, for example, the three are on the same plane. The concave shaping plate 5161 and the supporting shaping plate 5162 are integrally formed by bending a metal plate.

[0052] The shaping piece 516 is connected with the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 to further limit the internal shape of the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153 and the first concave 3121, so that the shaking amplitude can be further limited when the gas heater is shaken or pushed by external force, thereby improving stability.

[0053] The gas heater is placed perpendicular to the ground along the upright direction, and the support member 3 has an axial direction following the upright direction. A modeling angle is formed between the axial direction and a vertical line of the ground, and a shaping angle is formed between a surface extension direction of the supporting shaping plate 5162 and a surface extension direction of the concave shaping plate 5161. The modeling angle and the shaping angle are complementary angles.

[0054] The upper main body 312 has a length direction along the axial direction, the length of the upper main body 312 is less than 1409 mm, and the preferred length is 1152 mm to 1409 mm. The thickness of the male docking plate 515 is 0.9 mm to 1.1 mm, and the thickness of the shaping piece 516 is 1 mm to 2 mm. The total thickness of the upper main body 312, the male docking plate 515 and the concave shaping plate 5161 bonded together is 3 mm to 4 mm.

[0055] The thickness of the shaping piece 516 is preferably 1.5 mm. On the one hand, the thickness of the shaping piece 516 affects the attached area between the two ends of the shaping piece 516 and the first side panel bonding sheet 5152 and the second side panel bonding sheet 5153. The larger the bonding area, the higher the stability. On the other hand, the thickness of the shaping piece 516 also affects the bearing capacity of the upper part of the gas heater. Because the gravity of the upper part of the gas heater is evenly distributed to the gas chamber top plate 14 by the shaping piece 516, only a shaping piece 516 with sufficient thickness can stably support the upper part of the gas heater.

[0056] The aforementioned structure of the components installed on the supporting fulcrum and the thickness of each component not only facilitate assembly and secure combination, but also after the components are assembled, the overall thickness of the supporting fulcrum can firmly support the length of the upper main body 312 below 1409 mm, thereby preventing the gas heater from twisting and shaking.

[0057] In the fourth embodiment, the shape of the fixing frame corner 232 matches the shape of the first concave opening 3122, and the shape of the bottom plate corner 112, the shape of the top plate corner 142, and the shape of the second concave opening 3222 match. The overall stability of the heater is further improved through a larger contact area.

It is not intended to be exhaustive or to limit the disclosure to the precise form or to exemplary embodiments disclosed. Accordingly, the foregoing description should be regarded as illustrative rather than restrictive. Obviously, many modifications and variations will be apparent to practitioners skilled in this art.

first embodiment

[0029]In the first embodiment, referring to FIG. 1, a gas heater comprises a gas chamber 1, a heat conducting part 2 and a plurality of support members 3. The gas chamber 1 is used to place and connect a gas tank, and fuel gas is provided through the gas tank. The heat conducting part 2 is used to conduct heat energy generated by combustion in the gas chamber 1. The support members 3 are used to bear the weight of the heater as a whole.
