Abstract
Description
Technical Field
[0001] This application relates to the field of heated fire tubes, and more particularly to a heated fire tube structure. Background Technology
[0002] In the heating fields of dishwashers and water heaters, the heating element is the core heating element. It is generally connected to the ignition module and burns inside the heating element through the flame of the ignition module, thereby raising the surface temperature of the heating element to heat the water located outside the heating element.
[0003] Modern fire tubes typically have a heat inlet, a combustion chamber, and a heat outlet. Both the heat inlet and outlet are located along the width of the fire tube. One end of the combustion chamber is connected to the heat inlet, and the other end is connected to the heat outlet. The combustion chamber includes multiple horizontal combustion sections and multiple vertical combustion sections. Each horizontal combustion section is located along the length of the fire tube and is distributed along the width of the fire tube. Each vertical combustion section is located along the width of the fire tube, and the horizontal combustion sections are interconnected through the vertical combustion sections. When the fire tube is heated, the flame and heat flow enter the horizontal combustion section from the heat inlet and are heated by combustion in the next horizontal combustion section of the vertical heat flow section until the flame and heat flow out from the heat outlet, thus completing the heating and temperature rise of the fire tube.
[0004] Regarding the aforementioned technologies, to ensure that the heat generated by combustion is fully absorbed by the fire tube and then conducted to the medium to be heated (such as water or air), the traditional approach is to increase the length and volume of the fire tube. However, this results in excessively large equipment, which restricts application scenarios (equipment installation space) and leads to a significant waste of resources (steel). If the length or volume (heating area) of the fire tube is insufficient, the outlet temperature will be too high, which not only wastes energy but also poses a significant safety hazard (high temperature, incomplete combustion of liquefied gas and natural gas will result in large amounts of toxic and harmful substances such as sulfur dioxide and carbon dioxide). Summary of the Invention
[0005] In order to enable the heating fire tube to absorb the heat energy generated by combustion to the maximum extent and convert it into hot water, hot air and other necessities in daily life within a smaller space and shorter stroke, and at the same time to make the production of the fire tube more convenient, efficient and material-saving, and improve the heating effect of the heating fire tube, this application provides a heating fire tube structure.
[0006] The heating fire tube structure provided in this application adopts the following technical solution:
[0007] A heating tube structure includes two heating plates, which are fixedly connected to each other to form a first horizontal heating wall, a vertical heating wall, a connecting heating wall, and a second horizontal heating wall. The first horizontal heating wall, the vertical heating wall, and the connecting heating wall are connected in sequence.
[0008] Furthermore, the two heating plates are fixedly connected to each other to form a heat flow inlet, a combustion chamber, and a heat flow outlet, and the heat flow inlet, combustion chamber, and heat flow outlet are connected in sequence.
[0009] The combustion chamber includes a first horizontal heating section, a second horizontal heating section and a third horizontal heating section. The first horizontal heating section and the second horizontal heating section are separated by a first horizontal heating wall, and the second horizontal heating section and the third horizontal heating section are separated by a second horizontal heating wall.
[0010] The heating plate is formed with a left delay body, which includes a plurality of first left delay grooves, a plurality of second left delay grooves and a plurality of third left delay grooves. Each first left delay groove is evenly distributed along the length of the first horizontal heating part groove, each second left delay groove is evenly distributed along the length of the second horizontal heating part groove, and each third left delay groove is evenly distributed along the length of the third horizontal heating part groove.
[0011] Another heating plate is formed with a right delay body, which includes a plurality of first right delay grooves, a plurality of second right delay grooves and a plurality of third right delay grooves. Each of the first right delay grooves is evenly distributed along the length of the first horizontal heating part groove, each of the second right delay grooves is evenly distributed along the length of the second horizontal heating part groove, and each of the third right delay grooves is evenly distributed along the length of the third horizontal heating part groove.
[0012] By adopting the above technical solution, when the heating tube is used for intake heating, the flame and heat flow are slowed down by the left or right depressor when passing through it. This slows down the flow rate of the flame and heat flow in the combustion chamber, thereby increasing the residence time of the heat flow per unit area. This has an effect similar to increasing the heating surface and extending the heating time, thus improving heating efficiency. When the flame and heat flow reach the heat flow outlet, the heat from the flame and heat flow is almost completely absorbed by the heating plate. This allows the heating tube to absorb the heat energy generated by combustion to the maximum extent in a smaller space and shorter stroke, and then convert it into hot water, hot air, etc. needed in daily life. At the same time, the production of the heating tube is more convenient, efficient, and material-saving, improving the heating effect of the heating tube.
[0013] Optionally, each of the first left delay grooves and each of the first right delay grooves are staggered along the length direction of the first horizontal heating section groove;
[0014] Each of the second left delay grooves and each of the second right delay grooves are staggered along the length direction of the second horizontal heating section groove;
[0015] The third left delay groove and the third right delay groove are staggered along the length of the third horizontal heating section.
[0016] Optionally, the widths of the first and second horizontal heating walls are less than 3 millimeters.
[0017] Optionally, the heat inlet includes a first air inlet and a second air inlet, the first air inlet and the second air inlet are connected, and the top of the second air inlet is separated from one end of the third horizontal heating part by a connecting heating wall.
[0018] Optionally, the connecting heating wall is arc-shaped.
[0019] Optionally, the width of the tank of the first horizontal heating section is greater than the width of the tank of the second horizontal heating section, and the width of the tank of the second horizontal heating section is greater than the width of the tank of the third horizontal heating section.
[0020] Optionally, both heating plates are formed with a first air inlet groove and one or more second air inlet grooves, wherein the length direction of the first air inlet groove is arranged in the horizontal direction and the length direction of the second air inlet groove is arranged in the vertical direction.
[0021] Optionally, both heating plates are formed with venting grooves, and the length of the venting grooves is arranged in the vertical direction.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. When the heating element is used for intake heating, the flame and heat flow are slowed down by the left or right depressor, thus reducing the flow rate of the flame and heat in the combustion chamber. This increases the residence time of the heat in a unit area, similar to increasing the heating surface area, thereby improving heating efficiency. When the flame and heat flow reach the heat outlet, the heat is almost completely absorbed by the heating plate. This allows the heating element to absorb the heat energy generated by combustion to the maximum extent in a smaller space and shorter stroke, and then convert it into hot water, hot air, etc. needed in daily life. At the same time, the production of the heating element is more convenient, efficient, and material-saving, improving the heating effect of the heating element. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0034] This application discloses a heating fire tube structure.
[0035] Example 1.
[0036] Reference Figure 1 A heating tube structure includes two heating plates 1, which are rectangular. In this embodiment, the length direction of the two heating plates 1 is set to the horizontal direction, and the width direction of the two heating plates 1 is set to the vertical direction.
[0037] Reference Figure 2 Two heating plates 1 are fitted and fixed together to form a first horizontal heating wall 2, a vertical heating wall 3, a connecting heating wall 4, and a second horizontal heating wall 5. Therefore, in this embodiment, the width of the first horizontal heating wall 2, the vertical heating wall 3, the connecting heating wall 4, and the second horizontal heating wall 5 is 1 mm.
[0038] Reference Figure 2 The first horizontal heating wall 2, the vertical heating wall 3, and the connecting heating wall 4 are connected in sequence. The length of the first horizontal heating wall 2 and the second horizontal heating wall 5 extends horizontally, the length of the vertical heating wall 3 extends vertically, and the connecting heating wall 4 is arc-shaped.
[0039] Reference Figure 3 Two heating plates 1 are fixedly connected to form a heat flow inlet 11, a combustion chamber 12 and a heat flow outlet 13. The heat flow inlet 11, the combustion chamber 12 and the heat flow outlet 13 are connected in sequence. The heat flow inlet 11 includes a first air intake 111 and a second air intake 112. The first air intake 111 and the second air intake 112 are connected. The connecting heating wall 4 is located on the top of the second air intake 112.
[0040] Reference Figure 3 The combustion chamber 12 includes a first horizontal heating section 121, a second horizontal heating section 122 and a third horizontal heating section 123. The first horizontal heating section 121 is connected to the first air intake section 111, the first horizontal heating section 121 is connected to the second horizontal heating section 122, and the second horizontal heating section 122 is connected to the third horizontal heating section 123.
[0041] Reference Figure 3 The first horizontal heating section 121, the second horizontal heating section 122, and the third horizontal heating section 123 are all arranged horizontally along the length of the tank, and the first horizontal heating section 121, the second horizontal heating section 122, and the third horizontal heating section 123 are distributed vertically.
[0042] Reference Figure 2 and Figure 3 The first horizontal heating section 121 and the second horizontal heating section 122 are separated by the first horizontal heating wall 2. The second horizontal heating section 122 and the third horizontal heating section 123 are separated by the second horizontal heating wall 5. The end of the second horizontal heating section 122 near the heat flow inlet 11 is separated from the first air intake section 111 by the vertical heating wall 3. The end of the third horizontal heating section 123 near the heat flow inlet 11 is separated from the second air intake section 112 by the connecting heating wall 4.
[0043] Reference Figure 2 and Figure 3 The width of the tank of the first horizontal heating section 121 is greater than the width of the tank of the second horizontal heating section 122, and the width of the tank of the second horizontal heating section 122 is greater than the width of the tank of the third horizontal heating section 123.
[0044] Reference Figure 2 and Figure 3Both heating plates 1 are formed with a first air inlet groove 14 and two second air inlet grooves 15. The first air inlet groove 14 and the two second air inlet grooves 15 are located in the grooves corresponding to the first air inlet part 111. The length direction of the first air inlet groove 14 is set in the horizontal direction, and the length direction of the second air inlet groove 15 is set in the vertical direction. The two second air inlet grooves 15 and the first air inlet groove 14 are distributed in an H shape.
[0045] Reference Figure 2 and Figure 4 A heating plate 1 is formed with a left delay body 16. The left delay body 16 includes a plurality of first left delay grooves 161, a plurality of second left delay grooves 162 and a plurality of third left delay grooves 163. Each first left delay groove 161 is evenly distributed along the length of the first horizontal heating part 121, each second left delay groove 162 is evenly distributed along the length of the second horizontal heating part 122, and each third left delay groove 163 is evenly distributed along the length of the third horizontal heating part 123.
[0046] Reference Figure 2 and Figure 4 Another heating plate 1 is formed with a right delay body, which includes a number of first right delay grooves, a number of second right delay grooves and a number of third right delay grooves. Each first right delay groove is evenly distributed along the length of the first horizontal heating part 121, each second right delay groove is evenly distributed along the length of the second horizontal heating part 122, and each third right delay groove is evenly distributed along the length of the third horizontal heating part 123.
[0047] Reference Figure 2 and Figure 4 Each first left delay groove 161 and each first right delay groove are staggered along the length direction of the first horizontal heating section 121; each second left delay groove 162 and each second right delay groove are staggered along the length direction of the second horizontal heating section 122; each third left delay groove 163 and each third right delay groove are staggered along the length direction of the third horizontal heating section 123.
[0048] The arrangement of the left and right delay bodies 16 and 16 allows the heat flow to be delayed by the left or right delay body 16 when it passes through it. This causes the heat flow to remain in the left or right delay body 16, thereby increasing the heating time of the two heating plates 1 and ensuring the surface heating temperature of the heating plates 1.
[0049] Reference Figure 2 and Figure 4 Both heating plates 1 are formed with air outlet grooves 17, and the length of the air outlet grooves 17 is set in the vertical direction.
[0050] The implementation principle of Embodiment 1 is as follows: When the heating tube performs intake heating, the flame and heat flow are slowed down by the left or right depressor 16, thereby reducing the flow rate of the flame and heat in the combustion chamber. This increases the residence time of the heat flow per unit area, achieving an effect similar to increasing the heating surface and extending the heating time, thus improving heating efficiency. When the flame and heat flow reach the heat outlet 13, the heat from the flame and heat flow is almost completely absorbed by the heating plate 1, allowing the heating tube to heat the flame and heat in a smaller space and shorter stroke. The heat energy generated by combustion is fully absorbed to the maximum extent and converted into hot water, hot air, etc. needed in daily life; at the same time, the production of fire tubes is made more convenient, efficient and material-saving, improving the heating effect of the fire tubes. Meanwhile, after the combustion chamber 12 is fully heated, the heat is gradually absorbed by the water, so that the temperature of the combustion chamber 12 gradually decreases from the heat flow inlet 11 to the heat flow outlet 13, thereby ensuring that the temperature of the heat flow flowing to the heat flow outlet 13 is low, and ensuring that the exhaust fan installed at the heat flow outlet 13 to draw out the heat flow is not prone to overheating and damage.
[0051] Example 2.
[0052] The difference between Embodiment 2 and Embodiment 1 is that both heating plates 1 in Embodiment 2 are provided with three third air inlet grooves 18, each of which is arranged vertically and distributed horizontally.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
