Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, and in particular to a heating equipment. Background Art

[0002] At present, in the relevant technology, a direct-penetrating aluminum heating component is provided in the heating equipment. When the heating equipment is working, the heating component heats the gas in the heating equipment. Since the density of hot air is relatively small, the hot air rises, and the heating equipment inhales cold air with a larger density under the action of the air pressure, so as to heat the environment through the circulating exhausted hot air. However, since the direct-penetrating aluminum heating component is relatively long and the heat generated is dispersed, the circulation of hot and cold air in the heating equipment is slow. In order to improve the storage flexibility of the heating equipment, it is necessary to reduce the volume of the heating equipment, and then it is necessary to reduce the volume of the heating component inside the heating equipment, which will lead to a reduction in the heating area and affect the heating efficiency. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides a heating device.

[0005] In view of this, the first aspect of the utility model provides a heating device, including a shell assembly and a heating assembly, the shell assembly having a cavity, an air inlet and an air outlet, the shell assembly including a guide portion, the guide portion being located between the air inlet and the air outlet, the air inlet being connected to the air outlet through the cavity, the heating assembly being arranged in the cavity, being located between the air inlet and the air outlet, extending along the inner wall of the shell assembly, and the first end of the heating assembly being opposite to the second end of the heating assembly.

[0006] A heating device provided by the present application includes a shell component and a heating component. The heating device can prevent external pollutants from entering the heating device by setting the shell component. At the same time, the use of the shell component can facilitate the assembly and production of the heating device. The shell component has a cavity, an air inlet and an air outlet. The shell component includes a guide portion, which is located between the air inlet and the air outlet. The air inlet is connected to the air outlet through the cavity, thereby forming a gas flow channel for gas conduction. The heating component is arranged in the cavity, between the air inlet and the air outlet. When the heating device is working, external cold air enters the cavity of the heating device through the air inlet of the heating device. The heating component in the cavity heats the cold air in the cavity to form hot air. The gas density is small, and the hot air rises. As the hot air in the cavity rises, the gas in the cavity decreases, causing the air pressure in the cavity to decrease, which is lower than the air pressure value outside the heating device, forming a pressure difference inside and outside the heating device. Due to the low density of cold air, the cold air outside the cavity enters the heating device through the air inlet under the action of the pressure difference, thereby forming a hot and cold cycle inside and outside the heating device, allowing the heating device to inhale the surrounding cold air and heat it to form hot air, and disperse the hot air to the surrounding environment, thereby increasing the temperature of the surrounding environment, heating the surrounding environment, improving environmental comfort, and improving user experience. By setting the guide part, the hot air generated by the heating device when it is working can flow quickly, thereby improving the heating effect of the heating device.

[0007] Since the heating component extends along the inner wall of the shell component and the first end of the heating component is opposite to the second end of the heating component, the heating component is arranged along the inner wall of the shell component. When cold air enters the cavity through the air inlet, the heating component arranged along the inner wall can increase the contact with the cold air, thereby improving the heating efficiency of the heating component for the surrounding cold air. At the same time, the surrounding arrangement along the inner wall can make the heat generated by the heating component more concentrated, and can also make the cold air in the cavity evenly heated, thereby increasing the flow rate of the hot gas after heating, so as to improve the discharge rate of the hot air of the heating equipment and accelerate the hot and cold cycle speed of the heating equipment.

[0008] The heating component extends along the inner wall of the shell component to save installation space while ensuring uniform heating. The internal space of the shell component can be reasonably planned to reduce the volume, thereby reducing the size of the heating equipment while ensuring the heating effect, making it convenient to store and use the heating equipment.

[0009] When the heating device is working, on the guide path of the guide part, the ratio of the height of the shell component to the diameter of the radial section of the shell component can be controlled to make the hot air flow rising after heating flow quickly, increase the convection flow rate, and improve the heating effect.

[0010] The ratio of the height of the heating component to the path length of the guide portion can also be controlled to allow the rising hot air flow after heating to flow quickly, thereby increasing the flow rate and improving the heating efficiency of the heating equipment.

[0011] It is also possible to simultaneously control the ratio of the height of the shell component to the diameter of the radial cross-section of the shell component and the ratio of the height of the heating component to the path length of the guide portion, thereby achieving an increase in the hot air flow rate of the heating device to improve the warming effect of the heating device.

[0012] In addition, the heating device in the above technical solution provided by the utility model may also have the following additional technical features:

[0013] In some technical solutions of the present invention, optionally, there is a gap between the first end of the heating component and the second end of the heating component, and the heating device also includes an electric control component, which is connected to the heating component and is arranged in the gap.

[0014] In this technical solution, there is a gap between the first end of the heating component and the second end of the heating component, and the heating device also includes an electric control component, which is connected to the heating component and arranged in the gap. The heating device can be controlled by the electric control component to improve the working efficiency of the heating device, thereby improving the working effect of the heating device. The electric control component is arranged in the gap to avoid the high temperature generated by the heating component from affecting the electric control component, reduce the difficulty of material selection of the electric control component, and extend the service life of the electric control material. By arranging the electric control material in the gap, the space in the shell component can be reasonably planned. While ensuring the heating effect of the heating device, the electric control component can be protected from heat, and the volume of the heating device can be reduced, saving space, and facilitating the storage and use of the heating device.

[0015] Since the electric control device is arranged in the gap area, the radial space occupied by the electric control component in the shell component of the heating device can be reduced, thereby reducing the size of the shell component and saving costs.

[0016] In some technical solutions of the present invention, optionally, the shell assembly is cylindrical, and the height of the shell assembly is greater than or equal to 200 mm and less than or equal to 550 mm.

[0017] In this technical solution, the shell component is cylindrical. Since the heating component in the shell component heats the gas, the hot air will flow. By setting a cylindrical shell component, the resistance of the shell component to the flowing gas can be reduced, thereby increasing the flow rate of the gas and increasing the hot air discharge speed of the heating equipment to achieve the heating effect of the heating equipment. The height of the shell component is greater than or equal to 200 mm and less than or equal to 550 mm. By controlling the height of the shell component, the stamping process of the shell component can be facilitated, and the flow rate of the gas in the shell component can be increased while facilitating the processing, thereby increasing the flow rate of the gas and improving the heating effect of the heating equipment.

[0018] In some technical solutions of the present utility model, optionally, the cross-section of the shell component in the first direction is circular, elliptical or polygonal.

[0019] In this technical solution, the cross-section of the shell component in the first direction is circular, elliptical or polygonal, which can facilitate the processing of the shell component. When the cross-section of the shell component is designed to be circular, the inner wall of the shell component brings less resistance to the flowing gas, making the airflow in the shell component smoother, thereby facilitating the rapid discharge of hot air by the heating equipment. At the same time, the use of a shell component with a circular cross-section can facilitate the processing and production of the shell component, so the production efficiency of the shell component can also be improved.

[0020] When designing and manufacturing the heating device, a shell component of a suitable shape can also be selected according to the working parameters of the heating device and the internal space conditions.

[0021] In some technical schemes of the utility model, optionally, the cross-section of the shell component in the first direction is circular, and the ratio of the diameter of the cross-section to the height of the shell component in the second direction is greater than or equal to 0.45, and less than or equal to 0.65; or the cross-section of the shell component in the first direction is elliptical, and the ratio of the short axis length of the cross-section to the height of the shell component in the second direction is greater than or equal to 0.45, and less than or equal to 0.65; or the cross-section of the shell component in the first direction is polygonal, and the ratio of the diameter of the inscribed circle of the cross-section to the height of the shell component in the second direction is greater than or equal to 0.45, and less than or equal to 0.65.

[0022] In this technical solution, the cross section of the shell component in the first direction is circular, and the ratio of the diameter of the cross section to the height of the shell component in the second direction is greater than or equal to 0.45 and less than or equal to 0.65. When the heating device is working, cold air enters the shell component of the heating device through the air inlet of the heating device, and then the gas is heated by the heating component. The rising flow of hot air formed by the heating flows out through the air outlet, and the cavity in the shell component forms a gas flow channel. Under the condition that the height in the second direction is the same, the smaller the diameter of the cross section of the shell component in the first direction, the smaller the cross-sectional area, and thus the greater the air flow rate, and under the condition that the diameter of the cross section of the shell component in the first direction is the same Under the condition that the length of the shell assembly is shorter, the resistance of the inner wall to the flowing gas is smaller, and the airflow velocity in the shell assembly is smaller. Therefore, limiting the ratio of the cross-sectional diameter to the height of the shell assembly in the second direction to a range greater than or equal to 0.45 and less than or equal to 0.65 can increase the flow velocity of the hot air in the shell assembly, thereby improving the hot and cold cycle efficiency of the heating equipment, thereby improving the heating effect of the heating equipment on the surrounding environment. At the same time, setting the ratio of the cross-sectional diameter of the shell assembly to the height of the shell assembly in the second direction to a range greater than or equal to 0.45 and less than or equal to 0.65 can facilitate the production and processing of the shell assembly and improve production efficiency. The cross-section of the shell component in the first direction can also be set to be elliptical, and the ratio of the short axis length of the cross-section to the height of the shell component in the second direction is greater than or equal to 0.45 and less than or equal to 0.65. The cross-sectional area and height range of the shell component can be controlled, so that the flow rate of the hot air generated by the heating component in the shell component can be increased, thereby accelerating the discharge of the hot air and improving the heating effect of the surrounding environment; or the cross-section of the shell component in the first direction is polygonal, and the ratio of the diameter of the inscribed circle of the cross-section to the height of the shell component in the second direction is greater than or equal to 0.45 and less than or equal to 0.65. The cross-sectional area of ​​the shell component and the height of the shell component in the second direction can be controlled. The range of values ​​​​of the shell component can be controlled, so that the flow rate of the hot air generated by the heating component in the shell component can be increased, thereby accelerating the discharge of the hot air and improving the heating effect of the surrounding environment.

[0023] In some technical solutions of the present invention, optionally, the shell assembly includes a guide portion, which is located between the air inlet and the air outlet, wherein the ratio of the height of the guide portion in the second direction to the height of the shell assembly in the second direction is greater than or equal to 0.3 and less than or equal to 1.

[0024] In this technical solution, the shell assembly includes a guide part, which is located between the air inlet and the air outlet. The heating assembly heats the gas in the shell assembly when working, and the density of the generated hot air is small. The hot air in the shell assembly rises, which reduces the air pressure in the shell assembly, thereby causing a pressure difference between the inside and outside of the shell assembly. Under the action of the pressure difference, cold air is replenished, thereby forming a hot and cold cycle of the heating equipment. The provision of a guide component can increase the flow rate of the gas in the shell assembly and increase the exhaust speed of the hot air of the heating equipment, wherein the ratio of the height of the guide part in the second direction to the height of the shell assembly in the second direction is greater than or equal to 0.3 and less than or equal to 1, and the value range of the height of the guide part in the second direction and the height of the shell assembly in the second direction can be controlled, thereby improving the guiding effect of the guide part on the gas, accelerating the flow of gas, and accelerating the discharge of hot air, thereby improving the warming effect of the surrounding environment, improving the comfort of the surrounding environment, and facilitating user use.

[0025] The air inlet is located at the lower part of the circumferential wall of the shell assembly and / or the bottom of the shell assembly, and the air outlet is located at the upper part of the circumferential wall of the shell assembly and / or the top of the shell assembly.

[0026] In some technical solutions of the utility model, optionally, the shell assembly also includes an air inlet portion and an air outlet portion, the air inlet portion is connected to the flow guide portion and is located on the first side of the flow guide portion, the air inlet portion is provided with an air inlet, the air outlet portion is connected to the flow guide portion and is located on the second side of the flow guide portion, and the air outlet portion is provided with an air outlet.

[0027] In this technical solution, the shell assembly also includes an air inlet and an air outlet. The air inlet is connected to the guide portion and is located on a first side of the guide portion. The air inlet is provided with an air inlet. The air outlet is connected to the guide portion and is located on a second side of the guide portion. The air outlet is provided with an air outlet. When the heating device is working, the air inlet of the shell assembly facilitates the circulation of external cold air into the heating device. After being heated by the heating assembly, the hot air generated can be discharged through the air outlet provided on the second side of the guide portion, thereby improving the circulation effect of the gas, facilitating the discharge of hot air from the heating device, and improving the warming effect on the surrounding environment.

[0028] In some technical solutions of the present utility model, optionally, the ratio of the height of the heating component in the second direction to the height of the guide portion in the second direction is greater than or equal to 0.25 and less than or equal to 1.

[0029] In this technical solution, the ratio of the height of the heating component in the second direction to the height of the guide part in the second direction is greater than or equal to 0.25 and less than or equal to 1, so as to control the value range of the height of the heating component in the second direction and the height of the guide part in the second direction. When the cross-sectional area of ​​the shell component remains unchanged, the smaller the height of the guide part in the second direction, the smaller the resistance of the guide part to the flowing gas. Therefore, a heating component needs to be set in the shell component. By setting the height range of the guide part in the second direction to be greater than or equal to 0.25 times the height of the heating component in the second direction and less than or equal to 1 times the height of the heating component in the second direction, the gas guiding effect of the guide part can be further improved, the exhaust speed of hot air can be increased, the gas flow can be accelerated, the hot air can be discharged quickly, and the temperature of the surrounding environment can be increased.

[0030] In some technical solutions of the utility model, optionally, the air outlet area of ​​the air outlet is greater than or equal to 0.05 square meters, and the air intake area of ​​the air inlet is greater than the air outlet area of ​​the air outlet.

[0031] In this technical solution, the outlet area of ​​the air outlet is greater than or equal to 0.05 square meters, which can increase the exhaust volume of the air outlet. At the same time, the air intake area of ​​the air inlet is greater than the air outlet area of ​​the air outlet, which can increase the air outlet flow rate, quickly dissipate heat, improve heating efficiency, and reduce heat accumulation inside the shell assembly.

[0032] In some technical solutions of the present utility model, optionally, the distance between the heating component and the inner wall of the shell component is greater than or equal to 10 mm.

[0033] In this technical solution, the distance between the heating component and the inner wall of the shell component is greater than or equal to 10 mm. When the heating device is working, the heating component will generate heat. The range of values ​​for setting the distance between the heating component and the inner wall of the shell component can prevent excessive heat generated by the heating component from being introduced into the shell component, prevent the shell component from being overheated, and reduce the risk of scalding to the user. At the same time, setting a value greater than or equal to 10 mm can also prevent the heating component from expanding and contacting the shell component during heating, thereby improving the safety and reliability of the heating device.

[0034] In some technical solutions of the utility model, optionally, the shell assembly includes a base, a shell and a cover body, the shell is arranged on the base, the cover body is covered on the top of the shell and connected to the shell assembly, the cover body and the shell enclose a cavity, and the cover body is provided with an air outlet.

[0035] In this technical solution, the shell assembly includes a base, a shell and a cover. The base can improve the stability of the shell assembly when it is placed. The shell is arranged on the base to protect the interior of the heating device and prevent external pollutants from entering the heating device. The cover is arranged on the top of the shell and is connected to the shell assembly. The cover and the shell enclose a cavity. The cover is provided with an air outlet to prevent the heat generated by the heating assembly from accumulating at the bottom of the cavity, thereby reducing the temperature of the shell assembly and the cover, so as to reduce the probability of scalding the user due to high temperature of the shell assembly and the cover, thereby improving the safety and reliability of the heating device.

[0036] In some technical schemes of the utility model, optionally, the heating assembly includes a first bracket, a heating tube, a heat sink, a second bracket and a third bracket, the heating tube is arranged along the inner wall of the shell assembly on the first bracket and the base, the number of heat sinks is multiple, the multiple heat sinks are sleeved on the heating tube and arranged in parallel along the heating tube, the number of second brackets is at least two, at least two second brackets are respectively connected to the two ends of the heating tube and connected to the first bracket, and the third bracket is connected to the heating tube and connected to the first bracket.

[0037] In this technical solution, the heating component includes a first bracket, a heating tube, a heat sink, a second bracket and a third bracket. The heating tube is arranged along the inner wall of the shell component on the first bracket and the base. There are multiple heat sinks, which are sleeved on the heating tube and arranged in parallel along the heating tube. When the heating device is working, the heating tube will generate heat. At the same time, the multiple heat sinks sleeved on the heating tube can dissipate the heat generated by the heating tube, thereby heating the surrounding cold air, generating hot air, heating the surrounding environment, and improving the environmental comfort. There are at least two second brackets, at least two second brackets are respectively connected to the two ends of the heating tube and to the first bracket, and the third bracket is connected to the heating tube and to the first bracket. The heating tube is fixedly installed by at least two second brackets and the third bracket, so that the heating component is supported by at least three points, thereby improving the stability of the heating component, and thereby improving the safety and reliability of the heating device.

[0038] In some technical schemes of the utility model, optionally, a sliding hole is provided on one side of the second bracket close to the first bracket, and the heating assembly also includes a connecting piece, which is passed through the sliding hole and connected to the first bracket, wherein the heating tube extends in a circular shape, and the tangent direction of the circle where the heating tube is located at the sliding hole is the third direction, and the angle between the length direction of the sliding hole and the third direction is greater than or equal to 80 degrees and less than or equal to 100 degrees.

[0039] In this technical solution, a sliding hole is provided on one side of the second bracket close to the first bracket, and the heating component also includes a connecting piece, which is inserted into the sliding hole and connected to the first bracket, wherein the heating tube extends in a circular shape, and the tangent direction of the circle where the heating tube is located at the sliding hole is the third direction, and the angle between the length direction of the sliding hole and the third direction is greater than or equal to 80 degrees and less than or equal to 100 degrees. When the heating component is working, the heating component generates heat, and then the heating component will be deformed and thermally expanded. However, due to the different degrees of thermal expansion of various parts of the annular heating component, stress will be generated inside the heating component, and by controlling the value range of the angle between the length direction of the sliding hole and the third direction, it is convenient to release the internal stress of the heating component when it expands and deforms, and avoid excessive internal stress of the heating component causing damage to the heating component. Releasing internal stress through deformation reduces the probability of failure of the heating component and improves the working stability and safety of the heating equipment.

[0041] In this technical solution, the heating device also includes a first fan, which is located on the side of the heating component close to the air inlet. When the heating device is working, the heating component heats the gas, and the density of the generated hot air is small. The hot air will rise, thereby causing the air pressure in the cavity to decrease. Under the action of the air pressure difference inside and outside the cavity, cold air is replenished into the cavity to form convection, which facilitates the circulation of hot air into the air. At the same time, the first fan can accelerate the flow of gas in the cavity, further speeding up the exhaust of hot air, improving the heat dissipation efficiency of the heating device, and enhancing the heating effect of the heating device. A first heat dissipation coating is provided on the surface of the heating tube, which can improve the heat dissipation efficiency of the surface of the heating component, reduce the surface heat load of the heating component, extend the service life of the heating tube, reduce the use cost of the heating equipment, improve the heat transfer efficiency of the heating component to the cold air, and facilitate the heating component to heat the gas; the rated power of the heating tube is greater than or equal to 2000 watts, which can improve the heating efficiency of the heating tube, thereby improving the heating efficiency of the heating equipment, and can also increase the rapid convection of the gas in the cavity. The diameter of the circle where the heating tube is located is greater than or equal to 163 mm, and the area of ​​the heat sink is greater than or equal to 0.19 square meters, thereby increasing the contact between the heating tube and the cold air, and at the same time improving the heat transfer efficiency of the heating tube. By controlling the diameter of the circle where the heating tube is located and the area of ​​the heat sink, the production difficulty of the heating component can be reduced and the overall assembly efficiency can be improved.

The heat dissipation efficiency of the heating tube can be controlled, the heating effect of the heating tube can be improved, the assembly difficulty can be reduced, and the production cost of the heating component can be reduced.

[0044] In some technical solutions of the present utility model, optionally, the rated power of the heating tube is greater than or equal to 2000 watts, the diameter of the circle where the heating tube is located is greater than or equal to 206 mm, and the area of ​​the heat sink is greater than or equal to 0.39 square meters.

[0045] In this technical solution, the rated power of the heating tube is greater than or equal to 2000 watts, the diameter of the circle where the heating tube is located is greater than or equal to 206 mm, and the area of ​​the heat sink is greater than or equal to 0.39 square meters. By increasing the area of ​​the heat sink and the diameter of the circle where the heating tube is located, the heating effect of the heating tube can be guaranteed without changing the power. At the same time, the service life of the heating tube can be extended, and the production cost of the heating assembly can be further reduced.

[0046] In some technical schemes of the present invention, optionally, there are multiple heating tubes, and the number n of the heating tubes, the rated power P of the heating tubes, the surface load ω of the heating tubes, the diameter D1 of the circle where a single heating tube is located, and the diameter d of the cross section of the heating tube satisfy the following relationship: n=12.17×P / (ω×D1×d).

[0047] In this technical solution, there are multiple heating tubes, and the number n of the heating tubes, the rated power P of the heating tubes, the surface load ω of the heating tubes, the diameter D1 of the circle where a single heating tube is located, and the diameter d of the cross section of the heating tube satisfy the following relationship: n=12.17×P / (ω×D1×d). Since the surface load ω of the heating tube is determined by the material of the heating tube, the surface load ω of the heating tube of the corresponding material is fixed, and the cross-sectional diameter d of the heating tube is also a fixed model. Therefore, when the rated power of the heating tube remains unchanged, increasing the number of heating tubes can reduce the diameter D1 of the circle where the heating tube is located, thereby reducing the occupied area of ​​the heating tube in the cross section of the heating device in the second direction, and then reducing the cross-sectional diameter of the heating device, which is convenient for the storage and use of the heating device.

[0072] A heating device 100 provided in the present application includes a shell component 110 and a heating component 130. The heating device 100 can prevent external pollutants from entering the heating device 100 by setting the shell component 110. At the same time, the use of the shell component 110 can facilitate the assembly and production of the heating device 100. The shell component 110 has a cavity 112, an air inlet 114 and an air outlet 116. The shell component 110 includes a guide portion 117, and the guide portion 117 is located between the air inlet 114 and the air outlet 116. The air inlet 114 is connected to the air outlet 116 through the cavity 112, thereby forming a gas flow channel for gas conduction. The heating component 130 is arranged in the cavity 112, between the air inlet 114 and the air outlet 116. When the heating device 100 is working, external cold air enters the cavity 112 of the heating device 100 through the air inlet 114 of the heating device 100, and the heating component 130 in the cavity 112 Component 130 heats the cold air in cavity 112 to form hot air. Since the gas density of hot air is relatively small, the hot air rises. As the hot air in cavity 112 rises, the gas in cavity 112 decreases, causing the air pressure in cavity 112 to decrease and be lower than the air pressure value outside the heating device 100, forming a pressure difference inside and outside the heating device 100. Since the density of cold air is low, the cold air outside the cavity 112 enters the heating device 100 through the air inlet 114 under the action of the pressure difference, thereby forming a hot and cold cycle inside and outside the heating device 100, so that the heating device 100 can inhale the surrounding cold air and heat it to form hot air, and disperse the hot air to the surrounding environment, thereby increasing the temperature of the surrounding environment, heating the surrounding environment, improving the environmental comfort, and improving the user experience. By setting the guide part, the hot air generated when the heating device is working can flow quickly, thereby improving the heating effect of the heating device.

[0073] Since the heating component 130 extends along the inner wall of the shell component 110, and the first end of the heating component 130 is opposite to the second end of the heating component 130, the heating component 130 is arranged along the inner wall of the shell component 110. When cold air enters the cavity 112 through the air inlet 114, the heating component 130 arranged along the inner wall can increase the contact with the cold air, thereby improving the heating efficiency of the heating component 130 for the surrounding cold air. At the same time, the surrounding arrangement along the inner wall can make the heat generated by the heating component 130 more concentrated, and can also make the cold air in the cavity 112 evenly heated, thereby increasing the flow rate of the hot gas after heating, so as to improve the discharge rate of the hot air of the heating device 100 and accelerate the hot and cold cycle speed of the heating device 100.

[0074] The heating component 130 extends along the inner wall of the shell component 110, which can save the installation space of the heating component 130 while ensuring uniform heating. The internal space of the shell component 110 can be reasonably planned to reduce the volume, thereby reducing the size of the heating device 100 while ensuring the heating effect, making it convenient to store and use the heating device 100.

[0075] When the heating device 100 is working, on the guide path of the guide part 117, the ratio of the height of the shell component 110 to the diameter of the radial section of the shell component 110 can be controlled to make the hot air flow rising after heating flow quickly, increase the convection flow rate, and improve the heating effect.

[0076] The ratio of the height of the heating assembly 130 to the path length of the guide portion 117 can also be controlled to allow the rising hot air flow after heating to flow quickly, thereby increasing the flow rate and improving the heating efficiency of the heating device 100.

[0077] It is also possible to simultaneously control the ratio of the height of the shell assembly 110 to the diameter of the radial cross-section of the shell assembly 110 and the ratio of the height of the heating assembly 130 to the path length of the guide portion 117, thereby achieving an increase in the hot air flow rate of the heating device 100 to improve the warming effect of the heating device 100.

[0078] Specifically, if Figure 1 As shown, the first direction is S1 and the second direction is S2.

[0079] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0080] The cross-section of the shell component 110 in the first direction is circular, elliptical or polygonal.

[0081] In this embodiment, the cross-section of the shell component 110 in the first direction is circular, elliptical or polygonal, which can facilitate the processing of the shell component 110. When the cross-section of the shell component 110 is designed to be circular, the inner wall of the shell component 110 brings less resistance to the flowing gas, so that the airflow in the shell component 110 is smoother, thereby facilitating the rapid discharge of hot air by the heating equipment 100. At the same time, using a shell component 110 with a circular cross-section can facilitate the processing and production of the shell component 110, so the production efficiency of the shell component 110 can also be improved.

[0082] Specifically, Figure 3 As shown, the cross section of the shell component 110 in the first direction is circular, which reduces the resistance of the inner wall of the shell component 110 to the airflow and increases the flow rate of the gas.

[0083] Specifically, Figure 4 As shown, the cross-section of the shell component 110 in the first direction is elliptical, which reduces the resistance of the inner wall of the shell component 110 to the airflow, increases the flow rate of the gas, and facilitates production and installation.

[0084] Specifically, Figure 5 As shown, the cross-section of the shell component 110 in the first direction is a pentagon, which facilitates the stamping of the shell component 110 and reduces the manufacturing difficulty.

[0085] Specifically, Figure 6 As shown, the cross-section of the shell component 110 in the first direction is triangular, which improves the stability of the shell component 110 and facilitates the production of the shell component 110, thereby reducing the production cost.

[0086] Specifically, Figure 7 As shown, the cross-section of the shell component 110 in the first direction is hexagonal, and the hexagonal structure can facilitate the production and installation of the shell component 110.

[0087] Specifically, Figure 8 As shown, the cross-section of the shell assembly 110 in the first direction is rectangular, and the rectangular structure can facilitate the production and installation of the shell assembly 110 and reduce the manufacturing cost.

[0088] When designing and manufacturing the heating device 100 , a shell component 110 of a suitable shape may also be selected according to the working parameters of the heating device 100 and the internal space conditions.

[0089] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0090] A gap 172 is defined between the first end of the heating component 130 and the second end of the heating component 130 . The heating device 100 further includes an electric control component 170 , which is connected to the heating component 130 and disposed in the gap 172 .

[0091] In this embodiment, a gap 172 is formed between the first end of the heating component 130 and the second end of the heating component 130. The heating device 100 further includes an electric control component 170, which is connected to the heating component 130 and arranged in the gap 172. The electric control component 170 can be used to control the heating device 100, improve the working efficiency of the heating device 100, and thus improve the working effect of the heating device 100. The electric control component 170 is arranged in the gap 172 to avoid the high temperature generated by the heating component 130 from affecting the electric control component 170, reduce the difficulty of selecting materials for the electric control component 170, and extend the service life of the electric control component 170. By arranging the electric control material in the gap 172, the space in the shell component 110 can be reasonably planned. While ensuring the heating effect of the heating device 100, the electric control component 170 can be protected from heat, and the volume of the heating device 100 can be reduced, saving space, and facilitating the storage and use of the heating device 100.

[0092] Since the electric control device is arranged in the gap 172 area, the radial space occupied by the electric control component 170 in the shell component 110 of the heating device 100 can be reduced, thereby reducing the size of the shell component 110 and saving costs.

[0093] The shell component 110 is cylindrical, and the height of the shell component 110 is greater than or equal to 200 mm and less than or equal to 550 mm.

[0094] In this embodiment, the shell component 110 is cylindrical. Since the heating component 130 in the shell component 110 heats the gas, the hot air will flow. By setting the cylindrical shell component 110, the resistance of the shell component 110 to the flowing gas can be reduced, thereby increasing the flow rate of the gas, and increasing the hot air discharge speed of the heating device 100 to achieve the improvement of the heating effect of the heating device 100. The height of the shell component 110 is greater than or equal to 200 mm and less than or equal to 550 mm. By controlling the height of the shell component 110, the stamping process of the shell component 110 can be facilitated, and the flow rate of the gas in the shell component 110 can be increased while facilitating the processing, thereby increasing the flow rate of the gas and improving the heating effect of the heating device 100.

[0095] Specifically, Figure 1As shown, the height of the shell component 110 is H1, the height H1 of the shell component 110 may be 200 mm, the height H1 of the shell component 110 may be 300 mm, the height H1 of the shell component 110 may be 400 mm, and the height H1 of the shell component 110 may be 500 mm.

[0096] The cross-section of the shell component 110 in the first direction is circular, and the ratio of the diameter of the cross-section to the height of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65; or the cross-section of the shell component 110 in the first direction is elliptical, and the ratio of the short axis length of the cross-section to the height of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65; or the cross-section of the shell component 110 in the first direction is polygonal, and the ratio of the diameter of the inscribed circle of the cross-section to the height of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65.

[0097] In this embodiment, the cross section of the shell component 110 in the first direction is circular, and the ratio of the diameter of the cross section to the height of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65. When the heating device 100 is working, cold air enters the shell component 110 of the heating device 100 through the air inlet 114 of the heating device 100, and then the gas is heated by the heating component 130. The rising flow of hot air formed by the heating flows out through the air outlet 116, and the cavity 112 in the shell component 110 forms a gas flow channel. Under the condition that the height in the second direction is the same, the smaller the diameter of the cross section of the shell component 110 in the first direction, the smaller the cross-sectional area, and thus the greater the airflow velocity, and the cross section of the shell component 110 in the first direction is smaller. Under the condition of the same diameter, the shorter the length of the shell assembly 110, the smaller the resistance of the inner wall to the flowing gas, and the smaller the airflow velocity in the shell assembly 110. Therefore, limiting the ratio of the cross-sectional diameter to the height of the shell assembly 110 in the second direction to a range greater than or equal to 0.45 and less than or equal to 0.65 can increase the flow velocity of the hot air in the shell assembly 110, thereby improving the hot and cold cycle efficiency of the heating device 100, thereby improving the heating effect of the heating device 100 on the surrounding environment. At the same time, setting the ratio of the cross-sectional diameter of the shell assembly 110 to the height of the shell assembly 110 in the second direction to a range greater than or equal to 0.45 and less than or equal to 0.65 can facilitate the production and processing of the shell assembly 110 and improve production efficiency. The cross-section of the shell component 110 in the first direction can also be set to be elliptical, and the ratio of the short axis length of the cross-section to the height of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65. The range of values ​​of the cross-sectional area and height of the shell component 110 can be controlled, so that the flow rate of the hot air generated by the heating component 130 in the shell component 110 can be increased, thereby accelerating the discharge of the hot air and improving the heating effect of the surrounding environment; or the cross-section of the shell component 110 in the first direction is polygonal, and the ratio of the diameter of the inscribed circle of the cross-section to the height of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65. The range of values ​​of the cross-sectional area of ​​the shell component 110 and the height of the shell component 110 in the second direction can be controlled, so that the flow rate of the hot air generated by the heating component 130 in the shell component 110 can be increased, thereby accelerating the discharge of the hot air and improving the heating effect of the surrounding environment.

[0098] Specifically, Figure 1 As shown, the height of the shell assembly 110 in the second direction is H1.

[0099] Specifically, Fig. 9As shown, the cross-sectional area of ​​the shell component 110 in the first direction is circular, the diameter of the cross section is L1, and the ratio of the diameter L1 of the cross section to the height H1 of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65.

[0103] Specifically, Fig.13 As shown, when the cross section of the shell component 110 is a pentagon, the inscribed circle Y3 of the cross section pentagon is tangent to each side of the cross section, the diameter of the inscribed circle Y3 is L5, and the ratio of the diameter L5 of the inscribed circle Y3 to the height H1 of the shell component 110 in the second direction is greater than or equal to 0.45 and less than or equal to 0.65.

[0105] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0106] The shell assembly 110 includes a guide portion 117 , which is located between the air inlet 114 and the air outlet 116 , wherein a ratio of a height of the guide portion 117 in the second direction to a height of the shell assembly 110 in the second direction is greater than or equal to 0.3 and less than or equal to 1.

[0107] In this embodiment, the shell assembly 110 includes a guide portion 117, which is located between the air inlet 114 and the air outlet 116. The heating assembly 130 heats the gas in the shell assembly 110 when working, and the density of the hot air generated is small. The hot air in the shell assembly 110 rises, which reduces the air pressure in the shell assembly 110, thereby causing a pressure difference between the inside and outside of the shell assembly 110. Under the action of the pressure difference, cold air is replenished, thereby forming a hot and cold cycle of the heating device 100. The provision of the guide portion 117 can enhance the pressure of the gas in the shell assembly 110. The flow rate inside the heating device 100 is increased, and the exhaust speed of the hot air of the heating device 100 is increased, wherein the ratio of the height of the guide portion 117 in the second direction to the height of the shell component 110 in the second direction is greater than or equal to 0.3, and less than or equal to 1. The value range of the height of the guide portion 117 in the second direction and the height of the shell component 110 in the second direction can be controlled, thereby improving the guiding effect of the guide portion 117 on the gas, which can speed up the flow of gas, and then speed up the exhaust of hot air, improve the heating effect of the surrounding environment, improve the comfort of the surrounding environment, and facilitate user use.

[0108] Specifically, Figure 1 As shown, the height of the air guide portion 117 in the second direction is H2.

[0109] Specifically, the ratio of the height H2 of the guide portion 117 in the second direction to the height H1 of the shell assembly 110 in the second direction is greater than or equal to 0.3 and less than or equal to 1. The ratio of the height H2 of the guide portion 117 in the second direction to the height H1 of the shell assembly 110 in the second direction may be 0.3, the ratio of the height H2 of the guide portion 117 in the second direction to the height H1 of the shell assembly 110 in the second direction may be 0.5, the ratio of the height H2 of the guide portion 117 in the second direction to the height H1 of the shell assembly 110 in the second direction may be 0.7, and the ratio of the height H2 of the guide portion 117 in the second direction to the height H1 of the shell assembly 110 in the second direction may be 1.

[0110] The air inlet 114 is located at the lower portion of the circumferential wall of the shell assembly 110 and / or the bottom of the shell assembly 110 , and the air outlet 116 is located at the upper portion of the circumferential wall of the shell assembly 110 and / or the top of the shell assembly 110 .

[0111] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0112] The shell assembly 110 also includes an air inlet portion 113 and an air outlet portion 115. The air inlet portion 113 is connected to the guide portion 117 and is located on the first side of the guide portion 117. The air inlet portion 113 is provided with an air inlet 114. The air outlet portion 115 is connected to the guide portion 117 and is located on the second side of the guide portion 117. The air outlet portion 115 is provided with an air outlet 116.

[0113] In this embodiment, the shell assembly 110 also includes an air inlet 113 and an air outlet 115. The air inlet 113 is connected to the guide portion 117 and is located on the first side of the guide portion 117. The air inlet 113 is provided with an air inlet 114. The air outlet 115 is connected to the guide portion 117 and is located on the second side of the guide portion 117. The air outlet 115 is provided with an air outlet 116. When the heating device 100 is working, the air inlet 113 of the shell assembly 110 is conducive to the circulation of external cold air into the heating device 100. After being heated by the heating component 130, the hot air generated can be discharged through the air outlet 116 arranged on the second side of the guide portion 117, thereby improving the circulation effect of the gas, being conducive to the discharge of hot air from the heating device 100, and improving the warming effect on the surrounding environment.

[0114] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0115] The ratio of the height of the heating assembly 130 in the second direction to the height of the air guide portion 117 in the second direction is greater than or equal to 0.25 and less than or equal to 1.

[0116] In this embodiment, the ratio of the height of the heating component 130 in the second direction to the height of the guide portion 117 in the second direction is greater than or equal to 0.25 and less than or equal to 1, thereby controlling the value range of the height of the heating component 130 in the second direction and the height of the guide portion 117 in the second direction. Since the cross-sectional area of ​​the shell component 110 remains unchanged, the smaller the height of the guide portion 117 in the second direction, the smaller the resistance of the guide portion 117 to the flowing gas, and the heating component 130 is required to be set in the shell component 110. By setting the height range of the guide portion 117 in the second direction to be greater than or equal to 0.25 times the height of the heating component 130 in the second direction and less than or equal to 1 times the height of the heating component 130 in the second direction, the gas guiding effect of the guide portion 117 can be further improved, the exhaust speed of the hot air can be increased, the gas flow can be accelerated, the hot air can be discharged quickly, and the temperature of the surrounding environment can be increased.

[0117] Specifically, Figure 1As shown, the height H3 of the heating component 130 in the second direction, the ratio of the height H3 of the heating component 130 in the second direction to the height H1 of the guide portion 117 in the second direction may be 0.25, the ratio of the height H3 of the heating component 130 in the second direction to the height H1 of the guide portion 117 in the second direction may be 0.5, the ratio of the height H3 of the heating component 130 in the second direction to the height H1 of the guide portion 117 in the second direction may be 0.75, and the ratio of the height H3 of the heating component 130 in the second direction to the height H1 of the guide portion 117 in the second direction may be 1.

[0118] Table 1

[0119]

[0120] Specifically, as shown in Table 1 above, when the ratio of the height of the heating component 130 in the second direction to the height of the guide portion 117 in the second direction is 0.2, the ratio is less than 0.25. At this time, the wind speed at the air outlet 116 of the heating device 100 is 0.5 to 0.6 meters per second. When the ratio of the height of the heating component 130 in the second direction to the height of the guide portion 117 in the second direction is 0.5, the ratio is greater than 0.25 and less than 1. At this time, the wind speed at the air outlet 116 of the heating device 100 is 1.2 to 1.3 meters per second. Therefore, when the ratio of the height of the heating component 130 in the second direction to the height of the guide portion 117 in the second direction in the heating device 100 is controlled to be greater than or equal to 0.25 and less than or equal to 1 under rated power conditions, the gas guiding effect of the guide portion 117 can be further enhanced, the exhaust speed of hot air can be increased, the gas flow can be accelerated, and the heating of the surrounding environment can be accelerated.

[0121] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0122] The air outlet area of ​​the air outlet 116 is greater than or equal to 0.05 square meters, and the air inlet area of ​​the air inlet 114 is greater than the air outlet area of ​​the air outlet 116 .

[0133] like Fig.15 and Fig.16 As shown, the heating component 130 includes a first bracket 132, a heating tube 133, a heat sink 134, a second bracket 135 and a third bracket 136.

The number of the second brackets 135 is at least two, and at least two second brackets 135 are respectively connected to the two ends of the heating tube 133 and to the first bracket 132. The third bracket 136 is connected to the heating tube 133 and to the first bracket 132.

[0134] In this embodiment, the heating assembly 130 includes a first bracket 132, a heating tube 133, a heat sink 134, a second bracket 135 and a third bracket 136. The first bracket 132 is on the base 118, the heating tube 133 is arranged along the inner wall of the shell assembly 110, and the number of heat sinks 134 is multiple. The multiple heat sinks 134 are sleeved on the heating tube 133 and arranged in parallel along the heating tube 133. When the heating device 100 is working, the heating tube 133 will generate heat. At the same time, the multiple heat sinks 134 sleeved on the heating tube 133 can dissipate the heat generated by the heating tube 133, thereby achieving heat dissipation around The heating of cold air generates hot air, which heats the surrounding environment and improves the environmental comfort.

The third bracket 136 is connected to the heating tube 133 and to the first bracket 132. The heating tube 133 is fixedly installed by at least two second brackets 135 and the third bracket 136, so that the heating component 130 is supported by at least three points, thereby improving the stability of the heating component 130 and thereby improving the safety and reliability of the heating device 100.

[0135] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0136] like Fig.16 As shown, a sliding hole 137 is provided on one side of the second bracket 135 close to the first bracket 132, and the heating component 130 also includes a connecting piece 138, which is passed through the sliding hole 137 and connected to the first bracket 132, wherein the heating tube 133 extends in a circular shape, and the tangent direction of the circle where the heating tube 133 is located at the sliding hole 137 is the third direction, and the angle between the length direction of the sliding hole 137 and the third direction is greater than or equal to 80 degrees and less than or equal to 100 degrees.

[0137] In this embodiment, a sliding hole 137 is provided on one side of the second bracket 135 close to the first bracket 132, and the heating component 130 also includes a connecting piece 138, which is inserted into the sliding hole 137 and connected to the first bracket 132, wherein the heating tube 133 extends in a circular shape, and the tangent direction of the circle where the heating tube 133 is located at the sliding hole 137 is the third direction, and the angle between the length direction of the sliding hole 137 and the third direction is greater than or equal to 80 degrees and less than or equal to 100 degrees. When the heating component 130 is working, the heating component 130 generates heat, and then the heating component 130 will be deformed and thermally expanded.

By controlling the value range of the angle between the length direction of the sliding hole 137 and the third direction, it is possible to release the internal stress of the heating component 130 when it expands and deforms, thereby avoiding excessive internal stress of the heating component 130 and causing damage to the heating component 130. Internal stress is released through deformation, the probability of failure of the heating component 130 is reduced, and the working stability and safety of the heating device 100 are improved.

[0138] Specifically, Figure 2 As shown, the angle α between the length direction of the sliding hole 137 and the third direction can be 80 degrees, the angle α between the length direction of the sliding hole 137 and the third direction can be 90 degrees, the angle α between the length direction of the sliding hole 137 and the third direction can be 95 degrees, and the angle α between the length direction of the sliding hole 137 and the third direction can be 100 degrees.

[0139] Specifically, when the angle α between the length direction of the sliding hole 137 and the third direction is 90 degrees, the heating tube 133 has the best effect of releasing the internal stress through deformation.

When the heating device 100 is working, the heating component 130 heats the gas, and the density of the generated hot air is small. The hot air will rise, thereby causing the air pressure in the cavity 112 to decrease. Under the action of the air pressure difference between the inside and outside of the cavity 112, cold air is replenished into the cavity 112 to form convection, which facilitates the circulation of hot air into the air.

The diameter of the circle where the heating tube 133 is located is greater than or equal to 163 mm, and the area of ​​the heat sink 134 is greater than or equal to 0.19 square meters, thereby increasing the contact between the heating tube 133 and the cold air, and at the same time improving the heat transfer efficiency of the heating tube 133.

By providing the second heat dissipation coating 150, the surface heat load of the heating tube 133 can be reduced, thereby extending the service life of the heating tube 133. The rated power of the heating tube 133 is set to be greater than or equal to 2000 watts, the diameter of the circle where the heating tube 133 is located is greater than or equal to 190 mm, and the area of ​​the heat sink 134 is greater than or equal to 0.19 square meters. The heat dissipation efficiency of the heating tube 133 can be controlled, the heating effect of the heating tube 133 can be improved, the assembly difficulty can be reduced, and the production cost of the heating component 130 can be reduced.

[0148] By reducing the use of strong wind convection, costs can be reduced.

[0149] Specifically, Figure 2 As shown, the diameter D1 of the circle where the heating tube 133 is located is greater than or equal to 190 mm and less than or equal to 200 mm. The diameter D1 of the circle where the heating tube 133 is located can be 190 mm, the diameter D1 of the circle where the heating tube 133 is located can be 193 mm, the diameter D1 of the circle where the heating tube 133 is located can be 197 mm, and the diameter D1 of the circle where the heating tube 133 is located can be 200 mm.

[0150] Specifically, the second heat dissipation coating layer 150 may be graphene.

[0151] This embodiment provides a heating device 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0152] The rated power of the heating tube 133 is greater than or equal to 2000 watts, the diameter of the circle where the heating tube 133 is located is greater than or equal to 206 mm, and the area of ​​the heat sink 134 is greater than or equal to 0.39 square meters.

[0153] In this embodiment, the rated power of the heating tube 133 is greater than or equal to 2000 watts, the diameter of the circle where the heating tube 133 is located is greater than or equal to 206 mm, and the area of ​​the heat sink 134 is greater than or equal to 0.39 square meters. By increasing the area of ​​the heat sink 134 and the diameter of the circle where the heating tube 133 is located, the heating effect of the heating tube 133 can be guaranteed without changing the power, and the service life of the heating tube 133 can be extended. At the same time, the production cost of the heating assembly 130 can be further reduced.

[0154] Specifically, Figure 2As shown, the diameter D1 of the circle where the heating tube 133 is located is greater than or equal to 206 mm and less than or equal to 210 mm. The diameter D1 of the circle where the heating tube 133 is located can be 206 mm, the diameter D1 of the circle where the heating tube 133 is located can be 207 mm, the diameter D1 of the circle where the heating tube 133 is located can be 209 mm, and the diameter D1 of the circle where the heating tube 133 is located can be 210 mm.

[0157] In this embodiment, if Figure 2 As shown, there are multiple heating tubes 133, and the number n of the heating tubes 133, the rated power P of the heating tubes 133, the surface load ω of the heating tubes 133, the diameter D1 of the circle where a single heating tube 133 is located, and the diameter d of the cross section of the heating tube 133 satisfy the following relationship: n=12.17×P / (ω×D1×d). Since the surface load ω of the heating tube 133 is determined by the material of the heating tube 133, the surface load ω of the heating tube 133 of the corresponding material is fixed, and the diameter d of the cross section of the heating tube 133 is also a fixed model. Therefore, when the rated power of the heating tube 133 remains unchanged, increasing the number of heating tubes 133 can reduce the diameter D1 of the circle where the heating tube 133 is located, thereby reducing the occupied area of ​​the heating tube 133 in the cross section of the heating device 100 in the second direction, and then can reduce the cross-sectional diameter of the heating device 100, which is convenient for the storage and use of the heating device 100.

[0158] Specifically, as the number of the heating tubes 133 increases, the diameter of the ring in which the heating tubes 133 are located can be reduced, thereby reducing the space occupied by the heating assembly 130 .

[0159] Specifically, the heating tube 133 can also be made into other shapes, such as U-shape, L-shape, etc.

[0160] Specifically, the axis of the heating tube 133 is x, and the diameter of the circle where the heating tube 133 is located is D1.

[0161] Specifically, when the heating device 100 is working, due to the large density of cold air and the small density of hot air, the hot air in the closed cavity 112 can naturally flow upward from the bottom of the shell assembly. The bottom of the shell assembly 110 is a negative pressure area, which will continuously attract cold air into the bottom of the shell assembly 110, thereby circulating the air in the heated space to achieve a heating effect. The heating device 100 uses the chimney to heat the surrounding environment.

[0162] Specifically, the spacing between the heating component 130 and the shell component 110 is greater than or equal to 10 mm, the ratio of the height of the heating component 130 to the guide portion 117 is between 0.25 and 1, the ratio of the height of the guide portion 117 of the shell component 110 to the height of the shell component 110 is between 0.3 and 1, and the ratio of the diameter of the cross-section of the shell component 110 in the first direction to the height of the shell component 110 in the second direction is between 0.45 and 0.65, and the chimney effect in the heating device 100 is better.
