Description

Technical Field

[0001] The present application relates to the technical field of heaters, and more specifically, to an outdoor tower heater. Background Art

[0002] Outdoor tower heaters are a type of gas heater that utilize a combustion system to contain the flame within the heater's glass tube. However, due to the glass tube's poor thermal conductivity, outdoor heating effectiveness is relatively poor. To address this issue, existing technologies, such as the patent "An Enhanced Heat Radiant Glass Tube (Publication No.: CN220038594U)," employ a method of splitting the glass tube into two halves and inserting a semicircular metal mesh. However, this method places the glass tube and the mesh in close contact. However, due to the different thermal expansion coefficients of the glass tube and the mesh, the different cooling rates between the glass tube and the mesh result in a temperature difference between the inner and outer walls of the glass tube, which can easily lead to cracking of the glass tube.

[0005] The heater also includes a combustion net assembly located at the top of the heater, one end of the glass tube is fixed to the box body, and the other end of the glass tube is fixed to the combustion net assembly, and the height of the main body is less than the height of the glass tube.

[0006] The box body includes a top plate, which is located on the top of the box body and supports the glass tube and the heat increasing component.

[0007] The top plate includes a flange and a through hole. The flange protrudes upward and is a tube body with two ends opened. The through hole is located in the flange.

[0008] The heater further includes a fixing base, which is located on the top plate and supported by the top plate.

[0009] The fixing base comprises a first segment, a second segment, a third segment, a fourth segment and a protruding part, one end of the second segment is connected with the first segment, the other end of the second segment is connected with one end of the third segment, the other end of the third segment is connected with one end of the fourth segment, the second segment is above the first segment, the third segment is above the second segment, the fourth segment is above the third segment, and the protruding part is extended from the first segment or the second segment.

The box 1 is located at the lower part of the entire heater, the lower support 41 is located at the corners of the box 1, the upper support 42 is located above the lower support 41, and the protective element 43 is detachably arranged between adjacent two upper supports 42. The protective element 43 is used for placing the glass tube 5 so as to improve safety and protect the glass tube 5. The combustion net assembly 44 is located at the top of the entire heater, and the glass tube 5 is located at the middle of the entire heater.

[0030] The box 1 comprises a bottom plate, side plates and a top plate 11, and the bottom plate, the side plates and the top plate 11 are fixedly connected with the lower support 41. The bottom plate is used for supporting the gas tank located in the box 1. The side plates are arranged between adjacent lower supports 41, and are used for protecting the gas tank and improving the aesthetic appearance of the box 1. Ventilation holes are arranged between the side plates and the bottom plate, so as to prevent the gas of the gas tank from leaking and accumulating, and improve the safety of the heater in use.

[0031] One end of the lower support 41 abuts against the ground, and the other end of the lower support 41 is fixedly connected to one end of the upper support 42, and the other end of the upper support 42 is fixed to the combustion net assembly 44.

[0032] The box 1 is further provided with a combustion system 2, and the entire combustion system 2 includes a pipeline connected to a gas tank, a valve body for controlling gas, an ignition assembly for ignition, and a burner 21 for gas combustion. It can be understood that some components of the combustion system 2 can be located outside the box 1, such as a switch for controlling the size of the gas and an ignition switch.

[0033] The top plate 11 is provided with a through hole 111 and a flange 112 structure, the flange 112 protrudes upward, and the through hole 111 on the top plate 11 is defined by the inner wall of the flange 112 or located in the flange 112, and the flange 112 structure can improve the structural strength of the top plate 11 around the through hole 111. The top plate 11 is further provided with a fixing seat 12, the fixing seat 12 is detachably connected with the top plate 11, and the top plate 11 supports the fixing seat 12. One end of the glass tube 5 is connected with the combustion net assembly 44, and the other end of the glass tube 5 is connected with the fixing seat 12. The fixing seat 12 and the glass tube 5 are both hollow pipe bodies with both ends open, so that the airflow or flame can flow from the fixing seat 12 to the combustion net assembly 44 through the glass tube 5.

[0034] The connection between the glass tube 5 and the fixing seat 12 is further provided with a buffer 13, the fixing seat 12 supports the buffer 13, and the buffer 13 supports the glass tube 5, so as to have a damping effect on the glass tube 5 and reduce the possibility of cracking of the glass tube 5 due to vibration. The buffer 13 can be made of high-temperature-resistant silica gel or high-temperature-resistant glass fiber rope.

[0035] Specifically, the entire fixing seat 12 is made of an integrally formed sheet metal part, which is a hollow structure with both ends open. The fixing seat 12 includes a first section 121, a second section 122, a third section 123, and a fourth section 124. In the cross section of the face where the center points of the two ends are connected, the second section 122 and the fourth section 124 are horizontal structures, and the first section 121 and the third section 123 are vertical structures. The two ends of the second section 122 are respectively connected to one end of the first section 121 and one end of the third section 123, and one end of the fourth section 124 is connected to the other end of the third section 123. The first section 121 and the third section 123 are both circular ring structures, and the diameter of the first section 121 is smaller than the diameter of the third section 123. The first section 121 is located below the fourth section 124.

[0036] When the fixing base 12 is mounted to the top plate 11, the first section 121 is located within the through hole 111 of the top plate 11, and the flange 112 of the top plate 11 supports the second section 122, so that the first section 121 serves as a positioning element and the second section 122 serves as a support element, thereby improving the stability of the installation and fixation of the fixing base 12. The buffer 13 is located above the second section 122 and abuts against the second section 122. The glass tube 5 abuts against the buffer 13, so that the second section 122 supports the buffer 13, and the buffer 13 supports the glass tube 5. The glass tube 5 is located at one end of the buffer 13 and the buffer 13 is located within the cylindrical body formed by the third section 123. The buffer 13 abuts against the third section 123, so that the buffer 13 and the second section 122, and the buffer 13 and the third section 123 both have a sealing effect. The buffer 13 on one side protects the glass tube 5 to reduce vibration, and the sealing property of the other side buffer 13 reduces the possibility of flames escaping from the fixing base 12.

[0037] Fourth section 124 is located above third section 123. When installing or removing glass tube 5, fourth section 124 allows the holder 12 to be lifted. This allows the holder 12 to move the buffer 13 and glass tube 5 in the same direction. This facilitates installation of the holder 12 and glass tube 5, improving installation efficiency. A rolled edge is provided on the end of fourth section 124 facing away from third section 123, minimizing the risk of damage to the user from sheet metal corners during installation.

[0038] The opening of the glass tube 5 at one end of the fixing base 12, the first section 121 of the fixing base 12, the third section 123 of the fixing base 12, and the through hole 111 of the top plate 11 are projected onto the plane of the top plate 11. The projections of the glass tube 5, the first section 121, the third section 123, and the through hole 111 are all concentric circles. It is understood that the concentricity error of the projections of the glass tube 5, the first section 121, the third section 123, and the through hole 111 is less than 10%.

[0039] The heater is also provided with a heat increasing member 3, which includes a main body 31 and legs 32. The heat increasing member 3 is made of metal, and the main body 31 and the legs 32 are fixedly connected. The main body 31 is a hollow tube with two ends open, and the wall of the main body 31 is provided with a plurality of holes. The main body 31 is partially or completely located in the glass tube 5. In this embodiment, the main body 31 is completely located in the glass tube 5. The outer diameter of the main body 31 is smaller than the inner diameter of the glass tube 5. The distance between the wall of the main body 31 and the wall of the glass tube 5 is D (as shown in FIG. 1 ). Figure 4D is between 2mm and 35mm, such as 2mm, 4mm, 6mm, 8mm, 12mm, 16mm, 18mm, 22mm, 26mm, 28mm, 32mm, 35mm. When the main body 31 and the glass tube 5 are cooled from high temperature or heated from low temperature, due to the difference in material, the temperature rising or falling rate is different, thus the glass tube 5 and the main body 31 have temperature difference. Since the outer wall of the main body 31 does not contact the inner wall of the glass tube 5, the temperature difference between the inner wall and the outer wall of the glass tube 5 is small, and within the bearing range of the glass tube 5, the possibility of explosion or crack of the glass tube 5 caused by temperature difference is reduced.

[0040] The height of the main body 31 is less than the height of the glass tube 5, so as not to affect the original beauty of the tower type heater, and improve the heating effect of the tower type heater.

[0041] The support legs 32 are located at both ends of the main body 31. The support legs 32 located at the upper end of the main body 31 are three in number, one end of the support legs 32 is fixed to the main body 31, and the other end of the support legs 32 abuts against the glass tube 5 to stabilize the upper end of the main body 31 and improve the stability of the main body 31. The support legs 32 located at the lower end of the main body 31 are three in number, one end of the support legs 32 is fixedly connected to the main body 31, and the other end of the support legs 32 is fixedly connected to the fixing base 12 to improve the stability of the main body 31. Further, the support legs 32 further improve the stability of the main body 31.

[0042] Specifically, the fixing base 12 is provided with a protruding portion 125, which can be horizontally or vertically extended from the second section 122, or can be horizontally or vertically extended from the first section 121. The protruding portion 125 is fixedly connected to the support legs 32 located below the main body 31, and the fixing mode includes but is not limited to bolt fixing, welding fixing, clamping fixing, riveting fixing, etc. The fixing mode of the upper and lower support legs 32 to the main body 31 is the same as above.

[0043] The burner 21 of the combustion system 2 is located below the main plate, specifically, the combustion chamber is located below the through hole 111, the main body 31 is located above the through hole 111, and the projections of the main body 31, the burner 21 and the through hole 111 on the plane where the top plate 11 is located, the centers of the projections of the main body 31, the burner 21 and the through hole 111 overlap. It can be understood that the error of the concentricity of the projections of the main body 31, the burner 21 and the through hole 111 is less than 10%. Thus, the central axes of the burner 21, the through hole 111, the fixing base 12, the main body 31 and the glass tube 5 are collinear, so that the burner 21 is ignited more smoothly, and the flame enters the glass tube 5 more smoothly.

[0044] The box 1 is further provided with a decorative plate 14 located above the top plate 11, the decorative plate 14 is fixedly connected with the top plate 11, and the decorative plate 14 is provided with a mounting hole 141 for accommodating the fixing seat 12, and the mounting hole 141 is coaxial with the center axis of the through hole 111. Specifically, the third section 123 is located in the mounting hole 141 of the decorative plate 14, and the diameter of the mounting hole 141 of the decorative plate 14 is greater than the outer diameter of the third section 123, so as to facilitate the installation of the fixing seat 12. On the one hand, the decorative plate 14 improves the aesthetics of the connection between the top plate 11 and the fixing seat 12, and on the other hand, the decorative plate 14 can protect the top plate 11 and the fixing seat 12, and improve the structural strength of the top plate 11 and the fixing seat 12. The diameter of the mounting hole 141 is greater than the diameter of the through hole 111.

[0045] In other embodiments, the top plate 11 is not provided with the flange 112 structure, and the through holes 111 are arranged in the center of the top plate 11.

[0046] In other embodiments, the top plate 11 is not provided with the flange 112 structure, and the through holes 111 are arranged in the center of the top plate 11. When the fixing seat 12 is installed, the first section 121 can be placed in the through hole 111, so that the second section 122 abuts against the top plate 11, and the top plate 11 supports the entire fixing seat 12 through the second section 122; or the first section 121 of the fixing seat 12 can directly abut against the top plate 11, so that the top plate 11 supports the entire fixing seat 12 through the first section 121. At this time, the projection of the through hole 111 and the first section 121 on the plane of the top plate 11, the projection of the through hole 111 is located in the projection of the first section 121, and the projection of the through hole 111 is located in the projection of the first section 121. It can be understood that the concentricity of the projection of the through hole 111 and the first section 121 can have a difference within 10%.

[0047] In other embodiments, the fixing seat 12 structure can be cancelled, and the protruding part 125 is located on the top plate 11 and extends from the vicinity of the through hole 111 of the top plate 11. The leg 32 on the main body 31 is supported by the protruding part 125 on the top plate 11, and the buffer 13 is located on the main plate, the main plate supports the buffer 13, the glass tube 5 and the buffer 13 are located above the through hole 111, and the through hole 111 is surrounded by the buffer 13. The top plate 11 and the glass tube 5 are sealed by the buffer 13, reducing the possibility of flame leakage.

[0048] In other embodiments, the main body 31 of the heating element 3 has a leg 32 at the upper end, and the lower end of the main body 31 is cancelled, so that the lower end of the main body 31 abuts against the fixing seat 12; or the lower end of the main body 31 abuts against the protruding part 125 of the fixing seat 12, so as to improve the stability of the heating element 3. The heating element 3 and the glass tube 5 are both hollow cylindrical tubes with open ends.
