Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a heater with a heat-conducting structure. Background Technology

[0002] Traditional gas heaters typically use the heat generated by the combustion of combustible gas to directly heat the radiant panel, achieving space heating through thermal radiation or convection. However, in actual use, because the liquefied petroleum gas (LPG) stored in the cylinder needs to release fuel through a vaporization process, insufficient cylinder temperature in low-temperature environments may lead to reduced vaporization efficiency, thus affecting combustion stability and heating effect. Moreover, a small amount of LPG may remain in the cylinder and cannot be discharged, resulting in energy waste. In addition, in existing technologies, the heat generated by grate combustion is mostly concentrated on heating the radiant panel, and there is a lack of effective heat transfer design between the cylinder and the combustion area, resulting in the incomplete utilization of waste heat from combustion.

[0003] Optimizing the recovery path of combustion waste heat and directly increasing the cylinder temperature through heat conduction has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to provide a heater with a heat-conducting structure, which improves the vaporization efficiency of liquefied gas in the gas cylinder, ensures combustion stability and heating effect, and saves energy.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heater with a heat-conducting structure, comprising a gas cylinder, an ignition container, and a grate. The gas cylinder is used to store combustible gas. The ignition container is connected to the gas cylinder via a gas passage for igniting the combustible gas in the gas cylinder. A radiant panel is provided on the side of the grate away from the gas cylinder. The grate is located at the end of the gas passage between the ignition container and the gas cylinder. A heat-conducting plate is provided between the gas cylinder and the grate, forming a heat conduction path from the grate to the gas cylinder through the heat-conducting plate.

[0006] By adopting the above technical solution, the combustible gas in the gas cylinder reaches the ignition container through the gas pipeline. After being ignited by the ignition container, a flame is generated, releasing a large amount of heat energy. Then, infrared heat energy is radiated outward by the radiant panel in the grate. During the process of the grate radiating heat energy outward, since the heat-conducting plate is set between the grate and the gas cylinder, some of the heat energy is conducted to the gas cylinder through the heat-conducting plate, which raises the temperature of the gas cylinder, increases the flow rate of the combustible gas in the gas cylinder, improves the gasification efficiency, and heating the gas cylinder can discharge a small amount of residual gas in the gas cylinder, saving energy.

[0007] A further feature of this invention is that one end of the heat-conducting sheet forms a bent portion and conducts heat with the outer surface of the gas cylinder, while the other end extends to the grate and contacts the side wall of the grate.

[0008] By adopting the above technical solution, the bent part at one end of the heat-conducting plate is set to fit the outer contour of the gas cylinder, increasing the heat-conducting area of ​​the gas cylinder, and the other end forms a plate that fits the outer contour of the grate, increasing the heat-conducting area of ​​the grate.

[0009] A further feature of this invention is that the grate is provided with multiple combustion chambers, each combustion chamber is connected to the ignition container and the gas cylinder through its own pipeline, and each combustion chamber is connected to the gas cylinder through the heat-conducting plate to conduct heat.

[0010] By adopting the above technical solution, multiple combustion chambers can be independently controlled in zones, and the number of combustion chambers can be set up according to the needs to achieve the purpose of energy saving. Each combustion chamber is connected to the gas cylinder through heat conduction plates.

[0011] A further feature of this invention is that the heat-conducting sheet extends into multiple branch heat-conducting sheets, and each of the multiple branch heat-conducting sheets contacts the corresponding outer wall of the combustion chamber.

[0012] By adopting the above technical solution, each branch heat-conducting fin is set to fit the corresponding outer wall contour of the combustion chamber, increasing the heat-conducting area of ​​the combustion chamber and enhancing the heat conduction efficiency.

[0013] A further feature of this invention is that the heat-conducting sheet has several through grooves on its end face near the grate.

[0014] By adopting the above technical solution, several through slots are opened on the heat-conducting plate to absorb some of the thermal stress, thereby reducing the risk of deformation or cracking of the heat-conducting plate and improving structural stability.

[0015] A further feature of this invention is that it includes a protective cover and a housing. The protective cover covers the outside of the grate, and the surface of the protective cover is provided with a grid structure. The grid structure is composed of a plurality of evenly distributed through holes. The housing covers the heater and is fixedly connected to the protective cover.

[0016] By adopting the above technical solutions, the grid structure of the protective cover can prevent the human body from directly contacting the high-temperature panel and avoid burns. The shell protects the internal components of the heater and prevents external factors such as external impact, dust, and moisture from damaging the equipment, thus extending its service life.

[0017] A further feature of this invention is that a support is provided around the outer ring of the gas cylinder, the gas cylinder is disposed within the support, the support includes a first arc-shaped plate and a second arc-shaped plate that match the outline of the gas cylinder, and a hinge connecting the first arc-shaped plate and the second arc-shaped plate, wherein one of the arc-shaped plates rotates relative to the other via the hinge.

[0018] By adopting the above technical solution, the gas cylinder can be effectively prevented from shaking or tipping over by being surrounded by the support. The flip hinge on the support can open and close the first arc plate and the second arc plate, making it easy to remove the gas cylinder and facilitate the removal and installation of the gas cylinder.

[0019] A further feature of this invention is that the first arc-shaped plate and the second arc-shaped plate are provided with a detachable connection structure at their relatively rotating ends.

[0020] By adopting the above technical solution, the first arc plate and the second arc plate can be opened and closed through the detachable connection structure, which facilitates the removal and installation of gas cylinders.

[0021] A further feature of this invention is that a first magnetic plate is provided on the relatively rotating end of the first arc-shaped plate, and a second magnetic plate is provided on the relatively rotating end of the second arc-shaped plate. The first arc-shaped plate and the second arc-shaped plate are magnetically connected by the first magnetic plate and the second magnetic plate.

[0022] By adopting the above technical solution, the movable arc plate is rotated, and under the fixing action of the flip hinge, the relatively rotating end of the movable arc plate will gradually move closer to the relatively rotating end of the fixed arc plate until the first magnetic suction plate on the first arc plate and the second magnetic suction plate on the second arc plate are magnetically connected, thus completing the spatial constraint of the gas cylinder. The user can separate the first magnetic suction plate and the second magnetic suction plate to open the first arc plate and the second arc plate, which facilitates the replacement of the gas cylinder.

[0023] A further feature of this invention is that a hook-shaped structure is fixedly provided on the relatively rotating end of the first arc-shaped plate, and a rough-surface structure is fixedly provided on the relatively rotating end of the second arc-shaped plate. The first arc-shaped plate and the second arc-shaped plate are hooked and connected by the hook-shaped structure and the rough-surface structure.

[0024] By adopting the above technical solution, the movable arc plate is rotated, and under the fixing action of the flip hinge, the relative rotating end of the movable arc plate will gradually approach the relative rotating end of the fixed arc plate until the hook structure on the first arc plate and the rough surface structure on the second arc plate are hooked together, thus completing the spatial constraint of the gas cylinder. The user can separate the hook structure and the rough surface structure to open the first arc plate and the second arc plate, which facilitates the replacement of the gas cylinder.

[0025] In summary, this utility model has the following beneficial effects:

[0026] A heat-conducting plate is installed between the gas cylinder and the grate, forming a heat conduction path from the grate to the gas cylinder. Because the heat-conducting plate is located between the grate and the gas cylinder, some of the heat energy is conducted to the gas cylinder through the heat-conducting plate, which raises the temperature of the gas cylinder, increases the flow rate of combustible gas in the gas cylinder, thereby improving the gasification efficiency, ensuring combustion stability and heating effect, and heating the gas cylinder can also remove a small amount of residual gas in the gas cylinder, saving energy.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] A heater with a heat-conducting structure, such as Figure 1-6 As shown, the device includes a gas cylinder 1, an ignition container 2, and a grate 3. The gas cylinder 1 is used to store combustible gas. The ignition container 2 includes a thermocouple 21 and an igniter 22. The ignition container 2 is connected to the gas cylinder 1 via a gas path and is used to ignite the combustible gas in the gas cylinder 1. The igniter 22 generates a spark to ignite the gas. The flame heats the top of the thermocouple 21, generating a current to keep the gas valve open. If the flame goes out, the thermocouple 21 cools down, and the gas valve closes to prevent gas leakage. The grate 3 has a radiant panel 31 on the side away from the gas cylinder 1. The grate 3 is located at the end of the gas path between the ignition container 2 and the gas cylinder 1. A venturi tube is installed inside the grate 3. The grate 3 is connected to the ignition container 2 and the gas cylinder 1 via the venturi tube. A heat-conducting plate 5 is installed between the gas cylinder 1 and the grate 3, forming a heat conduction path from the grate 3 to the gas cylinder 1. The combustible gas in cylinder 1 reaches the ignition container 2 through the gas pipeline. After being ignited by the ignition container 2, it generates a flame and releases a large amount of heat energy. Then, the radiant panel 31 in the grate 3 radiates infrared heat energy outward. During the process of the grate 3 radiating heat energy outward, since the heat-conducting plate 5 is set between the grate 3 and the cylinder 1, some of the heat energy will be conducted to the cylinder 1 through the heat-conducting plate 5, which will raise the temperature of the cylinder 1, increase the flow rate of the combustible gas in the cylinder 1, improve the gasification efficiency, and heating the cylinder 1 can also discharge the small amount of residual gas in the cylinder 1, saving energy.

[0039] Preferably, one end of the heat-conducting sheet 5 forms a bent portion 51, which forms a heat conduction with the outer surface of the gas cylinder 1, and the other end extends to the grate 3 and contacts the side wall of the grate 3. The bent portion 51 at one end of the heat-conducting sheet 5 is set to fit the outer contour of the gas cylinder 1, increasing the heat conduction area of ​​the gas cylinder 1, and the other end forms a first piece 54 that matches the contour of the outer wall of the grate 3, increasing the heat conduction area of ​​the grate 3. The heat-conducting sheet 5 also includes a second piece 55 connecting the bent portion 51 and the first piece 54, and the second piece 55 provides support and a heat conduction path.

[0040] Preferably, the grate 3 is provided with multiple combustion chambers 32. Each combustion chamber 32 is connected to the ignition container 2 and the gas cylinder 1 through its own pipeline. Each combustion chamber 32 is connected to the gas cylinder 1 through the heat-conducting plate 5 to conduct heat, thereby ensuring the heating effect on the gas cylinder 1. In addition, the bends 51 on each heat-conducting plate 5 are set with respect to the contour of the gas cylinder 1, thereby providing a certain support for the gas cylinder 1 while conducting heat.

[0041] Preferably, the heat-conducting sheet 5 extends into multiple branch heat-conducting sheets 52, each of which contacts the outer wall of its corresponding combustion chamber 32. Each branch heat-conducting sheet 52 is interconnected and conforms to the contour of its corresponding combustion chamber 32 outer wall, increasing the heat-conducting area of ​​the combustion chamber 32 and enhancing heat conduction efficiency. As an example, the branch heat-conducting sheets 52 are all formed by bending.

[0042] Preferably, the heat-conducting plate 5 has several through slots 53 on its end face near the grate 3. Since the grate 3 generates a very high temperature, and the heat-conducting plate 5 is in direct contact with the side wall of the grate 3, the through slots 53 on the heat-conducting plate 5 absorb some of the thermal stress, reducing the risk of deformation or cracking of the heat-conducting plate and improving structural stability. As an example, the through slots 53 are arranged in an array with equal spacing from top to bottom.

[0043] Preferably, the device further includes a protective cover 6 and a housing 7. The protective cover 6 covers the outside of the grate 3, and the surface of the protective cover 6 is provided with a grid structure 61, which is composed of a plurality of evenly distributed through holes 62. The housing 7 covers the heater and is fixedly connected to the protective cover 6. The grid structure 61 of the protective cover 6 can prevent the human body from directly contacting the high-temperature panel and avoid burns. The housing 7 protects the internal components of the heater from damage caused by external impacts, dust, moisture and other external factors, thus extending its service life.

[0044] Preferably, a support 4 is provided around the outer ring of the gas cylinder 1, and the gas cylinder 1 is disposed within the support 4. The support 4 includes a first arc plate 41 and a second arc plate 42 that match the contour of the gas cylinder 1, and a hinge 45 connecting the first arc plate 41 and the second arc plate 42. The first arc plate 41 and the second arc plate 42 form a fixed end 43 and a movable end 44 at their junction, respectively. The hinge 45 is mounted on the fixed end 43. The fixed leaf 451 of the hinge 45 is fixedly connected to the first arc plate 41, and the movable leaf 452 of the hinge 45 is fixedly connected to the second arc plate 42. The second arc plate 42 is relatively movable through the hinge shaft 453 between the fixed leaf 451 and the movable leaf 452. The gas cylinder 1 is enclosed by the bracket 4, which effectively prevents the gas cylinder 1 from shaking or tipping over. The bracket 4 is equipped with a flip hinge 45, which allows the first arc plate 41 and the second arc plate 42 to open and close, making it easy to remove the gas cylinder 1 and facilitate its removal and installation. In addition, in the method of heat conduction from the heat-conducting plate 5 to the gas cylinder 1, the bracket 4 is added so that the heat-conducting plate is in direct contact with the bracket 4, which constitutes indirect heat conduction to the gas cylinder 1. This increases the temperature of the gas cylinder 1 to a certain extent without causing the gas cylinder 1 to become too hot.

[0045] Preferably, a foldable handle 8 is hinged to the upper part of the housing 7. When unfolded, the handle 8 forms a U-shaped grip 81, and when folded, it fits against the outer wall of the housing 7. The handle 8 fitting against the outer wall of the housing 7 reduces the overall size of the heater, making it easier to store or transport.

[0046] Example 2:

[0047] A heater with a heat-conducting structure, such as Figure 7 As shown, the difference between this embodiment and specific embodiment one is that: the relative rotating ends of the first arc plate 41 and the second arc plate 42 are provided with a detachable connection structure.

[0048] Preferably, a first magnetic plate 411 is provided on the relatively rotating end of the first arc-shaped plate 41, and a second magnetic plate 421 is provided on the relatively rotating end of the second arc-shaped plate 42. The first arc-shaped plate 41 and the second arc-shaped plate 42 are magnetically connected by the first magnetic plate 411 and the second magnetic plate 421. When the movable arc-shaped plate is rotated, under the fixing action of the flip hinge 45, the relatively rotating end of the movable arc-shaped plate will gradually move closer to the relatively rotating end of the fixed arc-shaped plate until the first magnetic plate 411 on the first arc-shaped plate 41 and the second magnetic plate 421 on the second arc-shaped plate 42 are magnetically connected, thus completing the spatial constraint of the gas cylinder 1. The user can separate the first magnetic plate 411 and the second magnetic plate 421 to open the first arc-shaped plate 41 and the second arc-shaped plate 42, which facilitates the replacement of the gas cylinder 1.

[0049] Example 3:

[0050] A heater with a heat-conducting structure, such as Figure 8 As shown, the difference between this embodiment and specific embodiment two is that: a hook surface structure 412 is fixedly provided on the relatively rotating end of the first arc plate 41, and a rough surface structure 422 is fixedly provided on the relatively rotating end of the second arc plate 42. The first arc plate 41 and the second arc plate 42 are hooked and connected by the hook surface structure 412 and the rough surface structure 422.

[0051] Rotating the movable arc plate, under the fixing action of the flip hinge 45, the relatively rotating end of the movable arc plate will gradually approach the relatively rotating end of the fixed arc plate until the hook surface structure 412 on the first arc plate 41 and the rough surface structure 422 on the second arc plate 42 hook together, thus completing the spatial constraint of the gas cylinder 1. The user can separate the hook surface structure 412 and the rough surface structure 422 to open the first arc plate 41 and the second arc plate 42, making it convenient to replace the gas cylinder 1.
