Description

Technical Field

[0001] The present invention relates to the technical field of heaters, and more specifically, it relates to a gas heater. Background Art

[0002] A gas heater is a device that generates heat by burning fuel to produce a flame. Such a device requires a combustion chamber and a heat transfer and dissipation part, and the combustion chamber and the heat transfer and dissipation part need to be connected together, usually fixed and connected by an aluminum alloy support.

[0003] Currently, the finished aluminum alloy supports on the market need to be reprocessed to meet the installation requirements of gas heaters, which wastes a long time. It is also possible to produce them by redesigning molds with suitable shapes. However, the mold opening cost is high. Therefore, it is considered whether the cost problem can be solved by sheet metal bending technology. However, after such sheet metal bending, there is a certain internal stress at the bending part, and this internal stress will cause the phenomenon of recovery deformation, which causes 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 after fixing the other side to the gas heater with some tools, the internal stress at the bending part cannot be released for a long time, and cracks will occur at the bending part, which will have a greater impact on the user experience.

[0004] Therefore, a gas heater is proposed to solve the problems of high production cost and large internal stress after the support is installed. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a gas heater with reduced production cost, reduced stress concentration, improved stability, and high installation efficiency.

[0006] To achieve the above object, the embodiments of the present invention provide the following technical solutions: A gas heater, comprising a gas chamber, a heat transfer part, and multiple groups of support members. The gas chamber includes a gas chamber bottom plate, multiple closed plates, a gas chamber top plate, and a combustion device. The gas chamber top plate and the gas chamber bottom plate are arranged up and down along the vertical direction of the gas heater. The upper end of the closed plate is connected to the gas chamber top plate, and the lower end of the closed plate is connected to the gas chamber bottom plate. The combustion device has a fire outlet. The heat transfer part includes a glass tube and a fixing frame. The glass tube is disposed directly above the fire outlet of the combustion device, and the fixing frame is installed on the upper side of the glass tube. The support members are divided into an upper support part and a lower support part along the vertical direction of the gas heater. The upper support part includes a first support piece, an upper main body part, and a second support piece. The upper main body part has a first concave area and a first concave area opening. The first concave area has two opposite first edges, and the two first edges define the first concave area opening. The first concave area protrudes towards the outside of the gas heater, and the first concave area opening faces the heat transfer part. The first support piece is connected to one of the first edges, and the second support piece is connected to the other first edge. The first support piece and the second support piece are connected to the gas chamber top plate and the fixing frame. The first support piece, the upper main body part, and the second support piece are integrally formed by bending a metal plate.

[0007] By adopting the above technical solutions, the upper support part and the lower support part are processed by the integral forming technology of bending a metal plate. Using finished metal plates, compared with the aluminum alloy casting forming, the production cost is low and the production efficiency is high. The stress at the bending part of the upper support part, through multiple bending points provided between the first support piece, the upper main body part, and the second support piece, enables the stress to be evenly distributed through multiple bending points, reducing the stress concentration. The lower support part is similar in shape to the upper support part and also has the effect of reducing stress concentration.

The first connecting rib connects the first fitting surface and the second fitting surface, and the first connecting rib, the first fitting surface and the second fitting surface are integrally formed by bending a metal plate. The first fitting surface and the second fitting surface are respectively in fitting connection with the first support piece and the second support piece, and the first connecting rib straddles the opening of the first concave region.

[0012] By adopting the above technical solution, the first reinforcing member fixes the upper support portion from one side of the opening of the first concave region, avoiding shaking when it is pushed by an external force, and improving the stability of the upper half of the heater.

[0013] The present invention is further configured such that: the lower support portion has a second reinforcing member, the second reinforcing member has a second connecting rib, a third fitting surface and a fourth fitting surface.

[0015] The present invention is further configured such that: the edge of the shaping piece is connected to the inner surface at the connection between the male docking plug board and the upper main body part, and the male docking plug board, the first support piece, the upper main body part and the second support piece are integrally formed by bending a metal plate.

[0016] The present invention is further configured such that: the lower support part has a connecting piece, the connecting piece is disposed on the upper end side of the lower support part and encloses a female docking groove with the upper end side of the lower support part, and the male docking plug board is inserted into the female docking groove.

[0017] The present invention is further configured such that: the male docking plug board has a concave area bottom attaching piece, a first side plate attaching piece and a second side plate attaching piece, the concave area bottom attaching piece connects the first side plate attaching piece and the second side plate attaching piece, and the concave area bottom attaching piece, the first side plate attaching piece and the second side plate attaching piece are integrally formed by bending a metal plate. The male docking plug board is placed inside the first inner concave area, the upper end part of the male docking plug board is attached to and connected with the lower end part of the upper main body part, the lower end part of the male docking plug board extends beyond the upper main body part and is inserted into the female docking groove, neither the first side plate attaching piece nor the second side plate attaching piece extends beyond the first end edge. The shaping piece has a concave area shaping board and a support area shaping board, the concave area shaping board is attached to and connected with the concave area bottom attaching piece, and both ends of the concave area shaping board are respectively attached to and connected with the first side plate attaching piece and the second side plate attaching piece. Both ends of the support area shaping board are respectively connected with the first support piece and the second support piece, and the lower surface of the support area shaping board does not extend beyond the lower end surfaces of the first support piece and the second support piece. The concave area shaping board and the support area shaping board are integrally formed by bending a metal plate.

[0018] By adopting the above technical solution, when the gas heater is shaken or pushed by an external force, the first side plate attaching piece and the second side plate attaching piece are attached to and connected with both ends of the first inner concave area, so that the first side plate attaching piece and the second side plate attaching piece can support each other with the first inner concave area, reduce the shaking amplitude and improve the stability. By the shaping piece being attached to and connected with the first side plate attaching piece and the second side plate attaching piece, the internal shapes of the first side plate attaching piece, the second side plate attaching piece and the first inner concave area are further restricted, and the shaking amplitude can be further restricted when the gas heater is shaken or pushed by an external force, thereby improving the stability.

[0019] The present invention is further configured such that: the gas heater is placed vertically perpendicular to the ground along the vertical direction, the support member has an axial direction along the vertical direction, there is a shaping angle between the axial direction and the perpendicular line of the ground, there is a shaping angle between the surface direction extension of the support area shaping plate and the surface direction extension of the concave area shaping plate, the shaping angle and the shaping angle are complementary to each other, the upper main body has a length direction along the axial direction, the length of the upper main body is 1409 mm or less, the thickness of the male docking plug board is 0.9 mm - 1.1 mm, the thickness of the shaping piece is 1 mm - 2 mm, and the total thickness after the upper main body, the male docking plug board and the concave area shaping plate are attached is 3 mm - 4 mm.

[0020] By adopting the above technical solution, through the relatively thick shaping piece, on the one hand, the thickness of the shaping piece affects the fitting area between the two ends of the shaping piece and the first side plate fitting piece and the second side plate fitting piece. The larger the fitting area, the higher the stability. On the other hand, the thickness of the shaping piece also affects the bearing capacity of the upper half of the gas heater. Since the gravity of the upper half of the gas heater is evenly distributed to the gas chamber top plate by the shaping piece, only a shaping piece with sufficient thickness can stably support the upper half of the gas heater.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. The upper support part, the closed plate and the lower support part are processed by the bending metal plate integral forming technology. It uses finished metal plates, which has a lower production cost and higher production efficiency compared with the aluminum alloy casting forming.

[0022] 2. The stress at the bending part of the upper support part, through multiple bending points arranged between the first support piece, the upper main body and the second support piece, enables the stress to be evenly distributed through multiple bending points, reducing the stress concentration; the lower support part is similar in shape to the upper support part and also has the effect of reducing stress concentration.

[0023] 3. The upper support part is fixed by the first reinforcing member to prevent it from shaking when being pushed by an external force, improving the stability of the upper half of the heater.

[0024] 4. Through the male docking plug board and the female docking groove, the installation efficiency of the user is improved.

[0025] 5. When the gas heater is shaken or pushed by an external force, the first side plate fitting piece and the second side plate fitting piece are attached to both end sides of the first concave area, enabling the first side plate fitting piece and the second side plate fitting piece to support each other with the first concave area, reducing the shaking amplitude and improving the stability. By the shaping piece being attached to the first side plate fitting piece and the second side plate fitting piece, the internal shape of the first side plate fitting piece, the second side plate fitting piece and the first concave area is further restricted, and the shaking amplitude can be further restricted when the gas heater is shaken or pushed by an external force, improving the stability.

[0026] 6. On the one hand, due to the relatively thick shaping piece, the thickness of the shaping piece affects the fitting area between both ends of the shaping piece and the first side plate fitting piece and the second side plate fitting piece. The larger the fitting 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. Since the gravity of the upper part of the gas heater is evenly distributed to the gas chamber top plate by the shaping piece, only a shaping piece with sufficient thickness can stably support the upper part of the gas heater.

[0029] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0031] Please refer to Figures 1-9 , the embodiments of the present invention provide the following technical solutions: Embodiment 1, refer to Figure 1, A gas heater, comprising a gas chamber 1, a heat transfer part 2 and multiple groups of support members 3. Among them, the gas chamber 1 is used to place and connect a gas cylinder to provide fuel through the gas cylinder. The heat transfer part 2 is used to conduct the heat energy generated by the combustion of the gas chamber 1. The multiple groups of support members 3 are used to bear the overall weight of the heater. The gas chamber 1 includes a gas chamber bottom plate 11, multiple closed 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 up and down along the vertical direction of the gas heater. The upper end of the closed plate 12 is connected to the gas chamber top plate 14, and the lower end of the closed plate 12 is connected to the gas chamber bottom plate 11. The combustion device 15 has a fire outlet; the gas chamber 1 further includes a panel 13. The closed plate 12 and the panel 13 are arranged around the gas chamber top plate 14 and the gas chamber bottom plate 11, and the combustion device 15 is placed below the gas chamber top plate 14; the heat transfer 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 covered directly above the fire outlet of the combustion device 15. The fixing frame 23 is installed on the upper side of the glass tube 21, and the infrared generator 22 is installed on the other side of the glass tube 21. There is a top cover 24 above the fixing frame 23, and the top cover 24 is fixedly connected to the fixing frame 23. Among them, the support of the heater is mainly realized by the support member 3. The original processing technology is to be formed by casting aluminum alloy. This aluminum alloy support member 3 has a special-shaped structure. Using this method for processing requires a separate mold opening, with a high mold opening cost. And during the product logistics packaging process, both the upper support part 31 and the lower support part 32 need to be separately packaged, wasting packaging time and also increasing the packaging cost.

[0032] Therefore, referring to Figure 3 , the support member 3 is divided into an upper support part 31 and a lower support part 32 along the vertical direction of the gas heater. The upper support part 31 includes a first support piece 311, an upper main body part 312 and a second support piece 313. The first support piece 311, the upper main body part 312 and the second support piece 313 are integrally formed by bending a metal plate. The lower support part 32 includes a third support piece 321, a lower main body part 322 and a fourth support piece 323. The third support piece 321, the lower main body part 322 and the fourth support piece 323 are integrally formed by bending a metal plate. The upper support part 31 and the lower support part 32 are processed by the integral forming technology of bending a metal plate. Using a finished metal plate, compared with the casting of aluminum alloy, the production cost is low and the production efficiency is high.

[0033] Referring to Figures 4-6, the upper main body portion 312 has a first concave area 3121 and a first concave area opening 3122. The first concave area 3121 has two opposite first end edges 31211, and the two first end edges 31211 define the first concave area opening 3122. The first concave area 3121 protrudes towards the outside of the gas heater, the first concave area opening 3122 faces the heat transfer portion 2, the first support piece 311 is connected to one first end edge 31211, the second support piece 313 is connected to the other first end edge 31211, and the first support piece 311 and the second support piece 313 are connected to the gas chamber top plate 14 and the fixing frame 23. The lower main body portion 322 has a second concave area 3221 and a second concave area opening 3222. The second concave area 3221 has two opposite second end edges 32211, and the two second end edges 32211 define the second concave area opening 3222. The second concave area 3221 protrudes towards the outside of the gas heater, the second concave area opening 3222 faces the gas chamber 1, the third support piece 321 is connected to one second end edge 32211, the fourth support piece 323 is connected to the other second end edge 32211, and the third support piece 321 and the fourth support piece 323 are connected to the gas chamber top plate 14 and the gas chamber bottom plate 11. The installation bolt holes 4 are provided at the joints where the support member 3 is in contact with the gas chamber bottom plate 11, the gas chamber top plate 14 and the fixing frame 23. When the first support piece 311 and the second support piece 313 are fixed to the gas chamber top plate 14 and the fixing frame 23 by bolts passing through the installation bolt holes 4, the metal plate that generates the restoring deformation is locked by the bolts, so that the first support piece 311 and the second support piece 313 are in contact with the gas chamber top plate 14 and the fixing frame 23. At this time, there is stress at its bending part. Through a plurality of bending points provided between the first support piece 311, the upper main body portion 312 and the second support piece 313, the stress can be evenly distributed through the plurality of bending points, reducing the stress concentration; the lower support portion 32 is similar in shape to the upper support portion 31 and also has the effect of reducing stress concentration.

[0034] Refer to Figures 2-7 , the closing plate 12 is located between two adjacent lower support portions 32 and connects the two adjacent lower support portions 32. One side of the lower support portion 32 is connected to the closing plate 12 through the third support piece 321, and the other side of the lower support portion 32 is connected to the closing plate 12 through the fourth support piece 323. The closing plate 12, the third support piece 321, the lower main body portion 322 and the fourth support piece 323 of the two adjacent lower support portions 32 are integrally formed by bending a metal plate. By integrally forming the closing plate 12 and the two lower support portions 32 by bending a metal plate, the production and installation efficiency is high, and the connection strength between them is high, improving the stability below the heater.

[0035] Refer to Figure 7, the lower support part 32 has a second reinforcing member 324. The second reinforcing member 324 has a second connecting rib 3242, a third fitting surface 3241 and a fourth fitting surface 3243.

The second reinforcing member 324 is placed below the bottom plate 11 of the gas chamber. The third fitting surface 3241 and the fourth fitting surface 3243 are respectively in fitting connection with the third support piece 321 and the fourth support piece 323. The second connecting rib 3242 straddles the opening 3222 of the second concave area. The strength of the heater feet is improved by the second reinforcing member 324, making the bottom more firm.

[0036] Refer to Figure 8 , the upper support part 31 and the lower support part 32 are connected by a plug-in structure. The upper support part 31 further includes a male docking plug board 315 and a shaping piece 316. The male docking plug board 315 is connected to the upper main body part 312, and a stepped structure is formed on the outer surface at the connection between the male docking plug board 315 and the upper main body part 312. The edge of the shaping piece 316 is connected to the inner surface of the connection. The shaping piece 316 is arranged in fitting connection with the upper surface of the top plate 14 of the gas chamber. A shaping screw hole 3161 is penetrated and opened at the fitting part of the shaping piece 316 and the top plate 14 of the gas chamber. The shaping screw hole 3161 is used to insert a bolt to fix the shaping piece 316 and the top plate 14 of the gas chamber. The male docking plug board 315, the first support piece 311, the upper main body part 312 and the second support piece 313 are integrally formed by bending a metal plate. The installation efficiency of the user is improved through the docking installation of the male docking plug board 315 and the female docking groove, and the stability above the heater is further improved through the connection between the shaping piece 316 and the top plate 14 of the gas chamber.

[0037] Refer to Figure 2 , the lower support part 32 has a connecting piece 325. The connecting piece 325 is arranged on the upper end side of the lower support part 32 and encloses a female docking groove with the upper end side of the lower support part 32. The male docking plug board 315 is inserted into the female docking groove. Among them, the height of the lower main body part 322 is about 878.2 mm, the overall thickness of the connecting piece 325 is 1 mm, and the length is about 50 mm, with a rough ratio of 1:18. The longer the length of the connecting piece 325, the more stable the upper end part of the lower main body part 322.

[0038] Refer to Figure 5, the surface of the gas chamber bottom plate 11 has a plurality of bottom plate edge pieces 111, and a set of bottom plate vertex regions 112 are formed at the intersection of two adjacent bottom plate edge pieces 111.

The bottom plate vertex regions 112, the top plate vertex regions 142, and the fixing frame vertex regions 232 are in contact with the first end edge 31211 or the second end edge 32211. By setting two contact points for each vertex region, the force is more evenly distributed, and the overall heater is more stable.

[0039] Embodiment 2. To strengthen the structural stability of the first inner concave region 3121 in Embodiment 1, refer to Figure 8 , the upper support portion 31 has a first reinforcing member 314. The first reinforcing member 314 has a first connecting rib 3142, a first fitting surface 3141, and a second fitting surface 3143. The first connecting rib 3142 connects the first fitting surface 3141 and the second fitting surface 3143, and 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 in fitting connection with the first support piece 311 and the second support piece 313, and the first connecting rib 3142 straddles the first concave region opening 3122. The upper support portion 31 is fixed from the inside of the upper main body portion 312 by the first reinforcing member 314, avoiding easy shaking when it is pushed by an external force, and improving the stability of the components above the heater.

The male docking plug board 515 is placed inside the first concave area 3121. The upper end of the male docking plug board 515 is fitted and connected to the lower end of the upper main body 312. The lower end of the male docking plug board 515 extends beyond the upper main body 312 to be inserted into the female docking groove. Neither the first side plate fitting piece 5152 nor the second side plate fitting piece 5153 extends beyond the first end edge 31211. When the gas heater is shaken or pushed by an external force, by the first side plate fitting piece 5152 and the second side plate fitting piece 5153 being fitted and connected to both end sides of the first concave area 3121, it can make the first side plate fitting piece 5152 and the second side plate fitting piece 5153 support each other with the first concave area 3121, reduce the shaking amplitude and improve the stability; The shaping piece 516 has a concave area shaping plate 5161 and a support area shaping plate 5162. The concave area shaping plate 5161 is fitted and connected to the concave area bottom fitting piece 5151, and both end sides of the concave area shaping plate 5161 are respectively fitted and connected to the first side plate fitting piece 5152 and the second side plate fitting piece 5153. Both end sides of the support area shaping plate 5162 are respectively connected to the first support piece 311 and the second support piece 313. The lower surface of the support area shaping plate 5162 is in the same plane as the lower end surfaces of the first support piece 311 and the second support piece 313. The concave area shaping plate 5161 and the support area shaping plate 5162 are integrally formed by bending a metal plate. By the shaping piece 516 being fitted and connected to the first side plate fitting piece 5152 and the second side plate fitting piece 5153, it further restricts the internal shapes of the first side plate fitting piece 5152 and the second side plate fitting piece 5153 and the first concave area 3121, and can further restrict the shaking amplitude when the gas heater is shaken or pushed by an external force and improve the stability; The gas heater is placed vertically perpendicular to the ground. The support member 3 takes the vertical direction of the gas heater as the axial direction of the support member 3. There is a shaping angle between the axial direction of the support member 3 and the ground perpendicular line. There is a shaping angle between the plane direction of the support area shaping plate 5162 and the plane direction of the concave area shaping plate 5161. The shaping angle and the shaping angle are complementary angles. The upper main body 312 has a length direction along the axial direction of the support member 3. The length of the upper main body 312 is 1409 mm or less, and the preferred length is 1152 mm - 1409 mm. The thickness of the male docking plug board 515 is 0.9 mm - 1.1 mm, the thickness of the shaping piece 516 is 1 mm - 2 mm, and the total thickness of the fitting parts of the upper main body 312, the male docking plug board 515 and the concave area shaping plate 5161 is 3 mm - 4 mm; Among them, 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 fitting area between the two ends of the shaping piece 516 and the first side plate fitting piece 5152 and the second side plate fitting piece 5153. The larger the fitting 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. Since the gravity of the upper part of the gas heater is evenly distributed by the shaping piece 516 to the gas chamber top plate 14, only the shaping piece 516 with sufficient thickness can stably support the upper part of the gas heater. Through the structures of the various components installed at the support fulcrum and the thickness dimensions of the various components, not only is the assembly convenient and the combination firm, but after the various components are assembled, the overall thickness of the support fulcrum can stably support the length of the upper main body 312 below 1409 mm, avoiding the twisting and shaking of the gas heater.

[0041] Embodiment 4: The shape of the top corner area 232 of the fixing frame is adapted to the shape of the opening 3122 of the first concave area, and the shapes of the bottom corner area 112, the top corner area 142 of the top plate and the opening 3222 of the second concave area are adapted. Through a larger contact area, the overall stability of the heater is further improved.

[0042] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
