Description

Technical Field

[0001] This utility model relates to the field of heater technology, specifically to an air conditioning device and a heater. Background Technology

[0002] Currently, in related technologies, some users typically use fan heaters for heating. However, due to the position of the heating element in existing products, which is usually located at the front of the fan, significant wind resistance is generated. The airflow is significantly attenuated after passing through the heating element, resulting in a lower final airflow speed and affecting the heating experience. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] In view of the above, an embodiment of the first aspect of the present invention provides an air conditioning device.

[0005] A second aspect of this utility model provides a heater.

[0006] To achieve the above objectives, an embodiment of the first aspect of this utility model provides an air conditioning device, comprising: a heating device; an air guide shroud corresponding to the heating device, the heating device being used to heat the air guide shroud; and an airflow regulating component disposed inside the air guide shroud, the airflow regulating component being used to discharge air toward the inner wall surface of the air guide shroud; wherein the air guide shroud is a rotating body, and on a plane passing through the axis of the air guide shroud, the size of the air inlet end of the air guide shroud is smaller than the size of the air outlet end of the air guide shroud.

[0007] The air conditioning device according to this utility model mainly includes an outer casing and a heating device, an air guide shroud, and an airflow regulating component disposed within the outer casing. Specifically, the heating device is the core of the air conditioning device, responsible for converting electrical energy into heat energy. The heating device is positioned opposite the air guide shroud, and it raises the temperature of the air guide shroud. Specifically, the heating element can be composed of high-temperature resistant resistance wire, or it may use more efficient materials such as PTC ceramics, or even an electromagnetic coil. The air guide shroud is positioned opposite the heating device, and its inner surface is heated by the heating device. Its specific shape design should facilitate uniform airflow distribution and heat exchange efficiency. The airflow regulating component is located inside the air guide shroud; its rotation generates a strong airflow, which is heated as it passes through the heated air guide shroud and ultimately discharged from the front of the unit. A motor provides power to rotate the impeller.

[0008] It is important to emphasize that in this design, the air guide shroud is a rotating body. On the plane passing through the axis of the air guide shroud, by limiting the size of the air inlet end of the air guide shroud to be smaller than the size of the air outlet end of the air guide shroud, that is, the air guide shroud is smaller at the back and larger at the front, forming a trumpet shape, so that after the air is blown out by the impeller, it will flow along the inner wall surface of the air guide shroud, so that the air blown out of the air conditioning equipment is diffused, thereby increasing the air supply area. With the combined action of the heating device and the air guide shroud, a large area warm air effect can be achieved.

[0009] The entire air guide shroud is designed to draw airflow in from the inlet, gradually heat and accelerate it, and finally discharge it at the outlet with a larger volume and higher temperature. This design maximizes the utilization of the airflow energy generated by the impeller and achieves highly efficient heat exchange through the heat energy provided by the heating device. The contour design of the air guide shroud makes the airflow inside smoother, reduces energy loss, and improves the overall performance of the heater, including increasing the outlet air temperature and air volume, while also helping to reduce noise. This design enables the heater to quickly provide warm and efficient heating in cold environments.

[0010] It is understandable that air conditioning equipment primarily converts electrical energy into heat and mechanical energy to generate hot air. In this solution, by adjusting the relative positions of the motor and impeller, and simultaneously adding a guide shroud structure, air is blown towards the guide shroud by the impeller. The guide shroud is heated by the heating device, increasing the temperature of the air blowing towards it. At the same time, the structural features of the guide shroud itself can guide the airflow to the outside of the air conditioning equipment, thereby providing warm air with a higher wind speed.

[0011] In some technical solutions, optionally, the outline of the air guide shroud includes a first profile line, a second profile line, and a third profile line connected sequentially from the air inlet end to the air outlet end, wherein the first profile line is a straight line, and the second and third profile lines are curves.

[0012] In this technical solution, the contour lines of the air guide shroud, as a rotating body, include three profile lines: the first profile line, the second profile line, and the third profile line. Specifically, the first profile line, as the starting part of the air inlet, is a straight line that helps to smoothly guide air into the air guide shroud, reducing turbulence and airflow loss during air intake. The straight profile line provides stable inlet conditions, laying a good foundation for the airflow to enter the subsequent curved profile line area, helping to maintain airflow stability and reduce noise. The second profile line, as the transition part connecting the first and third profile lines, is a curved profile line that is usually designed as an arc or other smooth curve to facilitate smooth airflow turning and acceleration. The curved profile line can effectively guide the airflow to concentrate at the air outlet, and due to its curvature design, it can accelerate the airflow without generating excessive resistance, increasing the kinetic energy of the airflow. The third profile line, as the air outlet part of the air guide shroud, is often designed to be wider to accommodate airflow expansion and decompression, while ensuring the uniformity of the outlet airflow. Through elliptical or other shaped curves, the third type of curve helps to smoothly diffuse airflow and evenly transfer heat, making the airflow softer and also further increasing the temperature of the airflow.

[0013] In some technical solutions, the third profile can optionally be an elliptical line, with the impeller and the air guide shroud arranged coaxially. In the axial direction of the air guide shroud, the tangent at the end of the third profile away from the second profile is parallel to the axis of the air guide shroud.

[0014] In this technical solution, the third profile serves as the air outlet of the air guide shroud. Its elliptical shape helps to gradually expand the flow cross-section of the airflow, which can reduce the airflow velocity, lower the dynamic pressure at the air outlet, and maintain sufficient static pressure so that the airflow can be discharged smoothly.

[0015] Since the tangent of the third type of line is parallel to the axis of the air guide, the airflow will not have any additional upward or downward deviation when leaving the air guide, thus ensuring the smooth discharge of the airflow, reducing airflow turbulence and energy loss, and helping to improve thermal efficiency and airflow uniformity.

[0016] The third-line design helps achieve smooth airflow and efficient heat exchange. The elliptical profile allows airflow to be discharged at a larger volume and higher temperature at the outlet of the air guide shroud, while maintaining a low noise level.

[0017] In some technical solutions, the second profile can optionally be an arc, and the radius of the second profile is related to the minimum distance between the second profile and the wind turbine.

[0018] In this technical solution, the second profile serves as the middle part connecting the first profile and the third profile. The arc design helps to smoothly guide the airflow from the narrower inlet to the wider outlet. At the same time, the curvature of the arc can be adjusted to change the airflow speed and direction as needed.

[0019] The radius of the arc directly affects the airflow path within the air guide. A smaller radius may increase airflow velocity, but it may also increase friction between the airflow and the inner wall of the air guide, thus increasing drag. Conversely, a larger radius can reduce airflow turbulence and friction against the inner wall, thereby reducing drag, but it may require more space.

[0020] In addition, the minimum distance between the second profile line and the wind turbine is also a key parameter, as it affects the initial conditions for airflow to enter the wind deflector from the wind turbine, including the airflow velocity and pressure distribution.

[0021] The arc shape of the second-type airflow and its distance from the wind turbine together determine the behavior of the airflow after entering the airflow guide. A reasonable arc radius and minimum distance can ensure a smooth airflow transition, reduce energy loss, and improve the overall efficiency of the airflow.

[0022] By optimizing the radius and minimum distance of the second-shaped curve, a balance point can be found, allowing the airflow to maintain sufficient kinetic energy while minimizing friction and wind resistance with the inner wall of the air guide, thereby improving the overall performance of the heater.

[0023] In some technical solutions, optionally, the ratio between the maximum diameter of the wind deflector and the maximum diameter of the wind turbine is 1.1 to 1.9.

[0024] In this technical solution, by limiting the ratio between the maximum diameter of the wind deflector and the maximum diameter of the wind turbine to 1.1–1.9, airflow acceleration can be affected. It can be understood that when airflow enters the wind deflector from the maximum diameter of the wind turbine, this ratio affects the degree of airflow acceleration. If the ratio is small, it indicates that the cross-section of the wind deflector is close to the cross-section of the wind turbine, and airflow acceleration is not significant; if the ratio is large, the cross-sectional expansion of the airflow within the wind deflector is greater, and the airflow velocity may decrease, but the pressure may increase.

[0025] Furthermore, a larger ratio helps the airflow regain pressure within the shroud, which is beneficial for reducing fan power consumption and improving overall system efficiency. Simultaneously, a larger shroud diameter provides a larger surface area without increasing resistance, contributing to improved heat exchange efficiency and allowing the airflow to gain more heat before leaving the shroud.

[0026] In summary, this ratio reflects not only the aerodynamics and heat exchange characteristics of the air guide shroud design, but also the overall noise level of the system. An optimized ratio balances fan energy consumption, airflow velocity, pressure distribution, and heat exchange efficiency, thus improving the overall performance of the heater. If the air guide shroud's cross-section is too narrow, it may result in excessively high airflow velocity and increased noise; conversely, a larger cross-section helps reduce noise, making the heater operate more quietly.

[0027] In some technical solutions, optionally, the impeller is located inside the air guide shroud along its axial direction, and there is a gap between the air outlet end face of the impeller and the front end face of the air guide shroud, the gap being greater than 5mm.

[0028] In this technical solution, by controlling the gap between the wind turbine and the wind guide to be greater than 5mm, it is ensured that the two do not come into contact, so that the wind turbine does not interfere with the wind guide when it rotates, and at the same time, airflow leakage and disturbance effects are reduced.

[0029] In some technical solutions, the airflow regulating component may optionally include: a fan wheel located inside the air guide shroud, the fan wheel rotating to expel air towards the inner wall of the air guide shroud and outward from the front side of the outer casing; and a motor, the drive shaft of which passes through the fan wheel and is used to drive the fan wheel to rotate.

[0030] By adjusting the relative positions of the motor and impeller, and by adding a structural guide shroud, air is blown towards the shroud by the impeller. The shroud is heated by the heating device, which increases the temperature of the air blowing towards it. At the same time, the structural features of the shroud itself can guide the air to the outside of the air conditioning equipment, thereby providing warm air with a higher wind speed.

[0031] The impeller, located inside the air guide shroud, generates a powerful airflow as it rotates. This airflow is heated as it passes through the heated shroud and ultimately exits from the front of the turbine head. An electric motor provides the power to rotate the impeller. The motor is designed to ensure sufficient torque to drive the impeller while also possessing good heat resistance.

[0032] It should be added that the motor type can be DC or AC, or even a brushless motor to improve efficiency and reduce maintenance; the motor power and speed must be matched with the design of the impeller; and the motor's heat dissipation design must ensure that it does not overheat during long-term operation.

[0033] In some technical solutions, optionally, the heating device is an electromagnetic coil, the air guide shroud is made of a magnetic material, and the heating device and the air guide shroud are spaced apart; or the heating device is an electric heating wire, the air guide shroud is made of a thermally conductive material, and the heating device is located on the air guide shroud.

[0034] In this technical solution, an electromagnetic coil is used as the heating device, and the air guide shroud is made of a magnetically conductive material. A gap is established between the heating device and the air guide shroud. By using an electromagnetic coil as the heating device, electromagnetic induction heating can be achieved. This method has advantages such as uniform heating and rapid response, which helps improve heating efficiency and control the heating temperature. Furthermore, the use of a magnetically conductive material for the air guide shroud helps guide the heat field, improves thermal efficiency, and reduces energy loss. Air is heated by the air guide shroud as it passes through, and then exhausted. It should also be noted that the gap between the heating device and the air guide shroud reduces the impact of the high temperature of the air guide shroud on the ambient temperature of the heating device, improving safety and protecting the heating device while extending its service life.

[0035] Alternatively, an electric heating wire can be used as a heating device to generate heat quickly. The heat-conducting air guide shroud helps to conduct heat quickly, improving heating efficiency and allowing the heated air to be delivered to the air duct structure more quickly.

[0036] The air guide shroud is made of a heat-conducting material, and the heating device is located on the air guide shroud. The heat-conducting material of the air guide shroud helps the heated air to be quickly conducted and discharged, thereby improving the utilization rate of hot air and ensuring stable output of hot air.

[0037] In some technical solutions, the outer casing may optionally include: a detachably connected front mesh cover and a rear mesh cover, the front mesh cover and the rear mesh cover being connected to form a housing cavity for accommodating the heating device, the air guide cover, the impeller and the motor.

[0038] In this technical solution, the outer casing includes a detachable front mesh cover and a rear mesh cover, which together form a cavity housing the heating device, air guide cover, impeller, and motor. The detachable front and rear mesh covers facilitate the maintenance and cleaning of the internal components, making repairs more convenient. This is highly beneficial for the daily maintenance and upkeep of the equipment.

[0039] The cavity formed by the connection of the front and rear mesh covers provides suitable space to house the heating device, air guide, impeller, and motor, allowing these internal components to be effectively installed and secured.

[0040] In summary, this enclosure design improves the ease of equipment maintenance and the stability of internal component installation, which is beneficial to the use and maintenance of the entire system.

[0041] A second aspect of this utility model provides a heater, comprising: any of the air conditioning devices described in the first aspect; and a base bracket detachably connected to the air conditioning device.

[0042] The heater according to this utility model includes a detachably connected air conditioning unit and a base bracket. The base bracket is detachably connected to the air conditioning unit, which facilitates assembly and disassembly, making the device more flexible, easier to transport and maintain. The base bracket provides stable support, helping to maintain the stability of the entire heater, reducing shaking and swaying during operation, and improving the safety and reliability of the device.

[0043] Furthermore, since the base bracket is detachably connected to the air conditioning equipment, different air conditioning equipment can be selected as needed, making the heater more widely applicable and flexible.

[0044] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention. Attached Figure Description

[0053] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0054] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0055] The following reference Figures 1 to 5 Some embodiments of the present invention are described below.

[0056] like Figure 1 and Figure 2 As shown, this embodiment proposes an air conditioning device 100, which mainly includes a housing 102 and a heating device 104, an air guide shroud 106, and an airflow regulating assembly 109 disposed within the housing 102. The airflow regulating assembly 109 includes a fan wheel 108 and a motor 110. Specifically, the housing 102 provides a robust protective shell for the air conditioning device 100, protecting the internal structure from damage and providing heat insulation and electrical insulation to ensure user safety. The heating device 104 is the core of the air conditioning device 100, responsible for converting electrical energy into heat energy. The heating device 104 is correspondingly arranged with the air guide shroud 106, and the heating device can raise the temperature of the air guide shroud. Specifically, the heating element can be composed of high-temperature resistant resistance wire, or may use more efficient materials such as PTC ceramic, or even an electromagnetic coil. The air guide shroud 106 is arranged opposite to the heating device 104, and its inner surface is heated by the heating device 104. The specific shape design should be conducive to uniform airflow distribution and heat exchange efficiency. The impeller is located inside the air guide shroud 106. Its rotation generates a powerful airflow, which is heated as it passes through the heated air guide shroud 106 and eventually discharged from the front of the head. An electric motor provides the power to rotate the impeller.

[0057] It should be emphasized that in this solution, the air guide shroud 106 is a rotating body. On the plane passing through the axis of the air guide shroud 106, by limiting the size of the air inlet end of the air guide shroud 106 to be smaller than the size of the air outlet end of the air guide shroud 106, that is, the air guide shroud 106 is smaller at the back and larger at the front, and is flared, so that after the air is blown out by the impeller, it will flow along the inner wall surface of the air guide shroud 106, so that the air finally blown out of the air conditioning device 100 is diffused, thereby increasing the air supply area. Under the combined action of the heating device 104 and the air guide shroud 106, a large area warm air effect can be achieved.

[0058] It should be added that, for the entire air conditioning unit, the front side is the air outlet side of the outer casing, i.e., the air outlet end of the air guide shroud, and the rear side is the air inlet side of the outer casing, i.e., the air inlet end of the air guide shroud, such as... Figure 2 The direction indicated by the middle arrow.

[0059] The design of the entire air guide shroud 106 involves introducing airflow from the inlet, gradually heating and accelerating it, and finally discharging it at the outlet with a larger volume and higher temperature. This design maximizes the utilization of the airflow energy generated by the impeller and achieves high-efficiency heat exchange through the heat energy provided by the heating device 104. The contour design of the air guide shroud 106 makes the airflow inside the shroud smoother, reduces energy loss, and improves the overall performance of the heater, including increasing the outlet air temperature and airflow, while also helping to reduce noise. This design enables the heater to quickly provide warm and efficient heating in cold environments.

[0060] It is understood that the air conditioning equipment 100 mainly converts electrical energy into heat and mechanical energy to generate hot air. In this solution, by adjusting the relative positions of the motor and the impeller, and by adding the structure of the air guide shroud 106, the air is blown into the air guide shroud 106 under the action of the impeller. The air guide shroud 106 is heated by the heating device 104, which can increase the temperature of the air blown into the air guide shroud 106. At the same time, the air guide shroud 106 itself can guide the air to the outside of the air conditioning equipment 100 through its structural features, thereby providing warm air with a higher wind speed.

[0061] It should be added that the motor type can be DC or AC, or even a brushless motor to improve efficiency and reduce maintenance; the motor power and speed must be matched with the design of the impeller; and the motor's heat dissipation design must ensure that it does not overheat during long-term operation.

[0062] In some embodiments, optionally, such as Figure 4As shown, the contour lines of the air guide shroud 106, as a rotating body, include three profile lines: the first profile line 1072, the second profile line 1074, and the third profile line 1076. Specifically, the first profile line 1072, as the starting part of the air inlet, is a straight line that helps to smoothly guide air into the air guide shroud 106, reducing turbulence and airflow loss during air intake. The straight profile line provides stable inlet conditions, laying a good foundation for the airflow to enter the subsequent curved profile area, helping to maintain airflow stability and reduce noise. The second profile line 1074, as the transition part connecting the first profile line 1072 and the third profile line 1076, is a curved profile line, usually designed as an arc or other smooth curve, to facilitate smooth airflow turning and acceleration. The curved profile line can effectively guide the airflow to concentrate at the air outlet, and due to its curvature design, it can accelerate the airflow without generating excessive resistance, increasing the kinetic energy of the airflow. As the air outlet portion of the air guide shroud 106, the third-type line 1076 is often designed to be wider to accommodate airflow expansion and pressure reduction, while ensuring uniform airflow. Through elliptical or other shaped curves, the third-type line 1076 helps to smoothly diffuse airflow and evenly transfer heat, making the airflow gentler and further increasing the temperature of the airflow.

[0063] In some embodiments, the third profile 1076 may serve as the air outlet of the air guide shroud 106. Its elliptical shape helps to gradually expand the flow cross-section of the airflow, which can reduce the airflow velocity, lower the dynamic pressure of the air outlet, and maintain sufficient static pressure so that the airflow can be discharged smoothly.

[0064] Since the tangent of the third type line 1076 is parallel to the axis of the air guide shroud 106, this means that the airflow will not produce additional upward or downward deviation when leaving the air guide shroud 106, thereby ensuring the smooth discharge of the airflow, reducing airflow turbulence and energy loss, and helping to improve thermal efficiency and airflow uniformity.

[0065] The design of the third type of line 1076 helps to achieve smooth airflow and efficient heat exchange. The elliptical profile allows the airflow to be discharged at the outlet of the air guide shroud 106 with a larger volume and higher temperature, while maintaining a low noise level.

[0066] In some embodiments, the second profile 1074 may serve as the middle section connecting the first profile 1072 and the third profile 1076. The arc design helps to smoothly guide the airflow from the narrower inlet end to the wider outlet end, while the curvature of the arc can be adjusted to adjust the airflow speed and direction as needed.

[0067] The radius of the arc directly affects the airflow path within the air guide shroud 106. A smaller radius may increase airflow velocity, but it may also increase friction between the airflow and the inner wall of the air guide shroud 106, thus increasing wind resistance. Conversely, a larger radius can reduce airflow turbulence and friction against the inner wall, thereby reducing wind resistance, but it may require more space.

[0068] In addition, the minimum distance between the second type line 1074 and the wind turbine is also a key parameter, as it affects the initial conditions of airflow entering the wind deflector 106 from the wind turbine, including the airflow velocity and pressure distribution.

[0069] The arc shape of the second-type line 1074 and its distance from the wind turbine together determine the behavior of the airflow after entering the wind deflector 106. A reasonable arc radius and minimum distance can ensure a smooth airflow transition, reduce energy loss, and improve the overall efficiency of the airflow.

[0070] By optimizing the radius and minimum distance of the second-type line 1074, a balance point can be found, so that the airflow can maintain sufficient kinetic energy while minimizing friction and wind resistance with the inner wall of the air guide shroud 106, thereby improving the overall performance of the heater.

[0071] In some embodiments, the ratio between the maximum diameter of the wind deflector 106 and the maximum diameter of the impeller can be limited to 1.1 to 1.9. This ratio can affect airflow acceleration. It is understood that when airflow enters the wind deflector 106 from the maximum diameter of the impeller, this ratio will affect the degree of airflow acceleration. If the ratio is small, it means that the cross-section of the wind deflector 106 is close to the cross-section of the impeller, and the airflow acceleration is not significant; if the ratio is large, the cross-sectional expansion of the airflow within the wind deflector 106 is greater, and the airflow velocity may decrease, but the pressure may increase.

[0072] Furthermore, a larger ratio helps the airflow regain pressure within the shroud 106, which is beneficial for reducing the power consumption of the fan and improving the overall system efficiency. At the same time, a larger diameter shroud 106 can provide a larger surface area without increasing resistance, which helps improve heat exchange efficiency, allowing the airflow to gain more heat before leaving the shroud 106.

[0073] In summary, this ratio reflects not only the aerodynamics and heat exchange characteristics of the air guide shroud 106 design, but also the overall performance of the heater. An optimized ratio balances the fan's energy consumption, airflow velocity, pressure distribution, and heat exchange efficiency. Furthermore, this ratio affects the system's noise level. If the cross-section of the air guide shroud 106 is too narrow, it may result in excessively high airflow velocity and increased noise; a larger cross-section helps reduce noise, making the heater operate more quietly.

[0074] In some embodiments, the gap between the impeller and the air guide is optionally greater than 5 mm to ensure that they do not contact each other, so that the impeller does not interfere with the air guide when rotating, and also reduces airflow leakage and disturbance effects.

[0075] In some embodiments, optionally, an electromagnetic coil is used as the heating device 104, the air guide shroud 106 is made of a magnetically conductive material, and a gap is provided between the heating device 104 and the air guide shroud 106. By using an electromagnetic coil as the heating device 104, electromagnetic induction heating can be achieved. This method has advantages such as uniform heating and rapid response, which is beneficial for improving heating efficiency and controlling heating temperature. In addition, the air guide shroud 106 is made of a magnetically conductive material, which helps to guide the heat field, improve thermal efficiency, and reduce energy loss. Air is heated by the air guide shroud when passing through it, and then discharged outwards. It should also be noted that the gap between the heating device 104 and the air guide shroud 106 reduces the impact of the high temperature of the air guide shroud on the temperature of the environment where the heating device is located, improves safety, and also helps to protect the heating device 104 and extend its service life.

[0076] In some embodiments, the outer casing 102 optionally includes a detachably connected front mesh cover 1022 and a rear mesh cover 1024, which are connected to form a receiving cavity for accommodating the heating device 104, the air guide shroud 106, the impeller 108, and the motor 110, wherein the front mesh cover 1022 is provided with a first bearing through which the drive shaft 1102 passes. The detachably connected front mesh cover 1022 and rear mesh cover 1024 are designed to facilitate the maintenance and cleaning of the internal components, making maintenance more convenient. This is very beneficial for the daily maintenance and upkeep of the equipment.

[0077] The cavity formed by the connection of the front mesh cover 1022 and the rear mesh cover 1024 provides suitable space to house the heating device 104, the air guide cover 106, the impeller 108 and the motor 110, so that these internal components can be effectively installed and fixed.

[0078] It should be added that the front grille 1022 is provided with a first bearing through which the drive shaft 1102 passes, which helps to support and fix the drive shaft 1102, ensuring the stable operation of the drive shaft 1102 and reducing vibration and friction caused by the movement of the drive shaft 1102.

[0079] In summary, the design of this outer casing 102 improves the ease of maintenance of the equipment and the installation stability of internal components, which is beneficial to the use and maintenance of the entire system.

[0080] It should be noted that the structure of the entire outer shell 102 is a fully enclosed structure in the middle, forming a ring shell, with grilles set at the front and rear. At least one of the front mesh cover 1022 and the rear mesh cover 1024 will be designed with an intermediate shell, that is, the intermediate shell can be part of the front mesh cover 1022 or the rear mesh cover 1024.

[0081] In some embodiments, an electric heating wire is optionally used as the heating device 104, which can quickly generate heat. The heat-conducting air guide shroud 106 helps to conduct heat quickly, improves heating efficiency, and allows the heated air to be delivered to the air duct structure 114 more quickly.

[0082] The air guide shroud 106 is made of a heat-conducting material, and the heating device 104 is mounted on the air guide shroud 106. The heat-conducting material of the air guide shroud 106 helps the heated air to be quickly conducted and discharged, thereby improving the utilization rate of hot air and ensuring the stable output of hot air.

[0083] This application proposes another embodiment of the heater 200, such as... Figure 5 As shown, the device includes a detachably connected air conditioning unit 100 and a base bracket 202. The base bracket 202 is detachably connected to the air conditioning unit 100. This design facilitates the assembly and disassembly of the device, making it more flexible, easier to transport and maintain. The base bracket 202 provides stable support, helping to maintain the stability of the entire heater 200, reducing shaking and swaying during operation, and improving the safety and reliability of the device.

[0084] Furthermore, since the base bracket 202 is detachably connected to the air conditioning unit 100, different air conditioning units 100 can be selected as needed, making the heater 200 more widely applicable and flexible.

[0085] In one specific embodiment, a heat exchanger structure with IH sidewall heating is proposed, such as... Figure 3 As shown, the overall structure includes a motor 110, a front grille 1022, a fan 108, an outer shell (i.e., outer shell cover 102), a heating element (i.e., air guide 106), a heating element bracket (i.e., heat insulation bracket 1062), a coil bracket (i.e., heating bracket 1042), and an air duct (i.e., air duct structure 114). The overall design uses a centrifugal fan (i.e., fan 108 + motor 110) as the power unit. The centrifugal fan has the characteristics of axial air intake and radial air exhaust, and the outlet airflow is thrown out under the action of centrifugal force. The side wall of the power unit is made of magnetically conductive metal parts, which are heated through electromagnetic induction. During operation, the airflow is heated by passing through the heated side wall, thereby achieving the warm air function.

[0086] The overall structure is arranged as follows: First, the heating element must be made of a magnetically conductive metal (commonly including 430 stainless steel, iron, etc.). During operation, the heating element heats up due to electromagnetic induction. The heating element is fixed to a heating element bracket, which is typically made of high-temperature resistant plastic (nylon + fiberglass, etc.). The bracket serves two purposes: first, to fix the heating element; second, to provide heat insulation. Since the heating element can reach temperatures exceeding 200 degrees Celsius during operation, conventional electronic components cannot withstand such temperatures, so a plastic bracket is needed to wrap around it, providing some insulation. Outside the heating element bracket is a coil support. An electromagnetic coil is wound on the coil, which generates an alternating magnetic field when energized, thereby heating the heating element. The heating element bracket and the coil support are jointly fixed to the air duct structure.

[0087] When the fan rotates, it does work on the air, which gains kinetic energy and moves in a spiral motion, moving forward along the axis of the air guide shroud. Simultaneously, because the air guide shroud is heated, the air is gradually heated as it moves forward. The air guide shroud in this system serves two purposes: first, to guide the airflow, and second, to heat it, without adding additional airflow resistance, thus significantly increasing the overall airflow velocity. In contrast, traditional warm air heaters use a PTC (Power Transmission Control Unit) placed in front of the fan, resulting in very high airflow resistance and minimal air output.

[0088] like Figure 4 As shown in the cross-sectional view, the basic profile of the wind deflector consists of three curves, named curve 01 (the first profile), curve 02 (the second profile), and curve 03 (the third profile), with endpoints a, b, c, and d. The vertical distance between endpoints a and b is S1, the vertical distance between endpoints b and c is S2, and the vertical distance from endpoint d to the outermost section of the wind turbine is S3. The minimum distance between curve 02 and the wind turbine is S4.

[0089] The design process of the air guide shroud is as follows: When designing the air guide shroud, first determine the starting point b of curve 02 based on the vertical distance (S1) between the leftmost part of the impeller and the inlet of the air guide shroud. The value range of S1 is generally 5-40mm. Curve 01 is generally designed as a straight line segment. Determine the position of point c based on the axial width S2 of the annular isolation ring on the left side of the impeller. Since curve 02 is generally designed as an arc, the radius of the arc is determined by S4 (S4 is the minimum distance from curve 02 to the impeller, and its value range is generally 3-12mm). After determining points b and c and the radius of the arc, the design of curve 02 can be completed.

[0090] Curve 03 is an elliptical curve, satisfying the equation (xh)² / a² + (yk)² / b² = 1, where (h,k) are the coordinates of the center point of the ellipse, and a and b are the semi-major axes of the ellipse on the x and y axes, respectively. In the design, the airflow is generally directed to exit at point d along a direction parallel to the axis, so the diameter W1 at the outlet is 2a (using the straight line at the outlet section as the x-axis).

[0091] The position of point d is determined by the distance S3 between the outlet section and the rightmost side of the impeller, where S3 is generally greater than 5mm. The semi-major axis length b can then be calculated based on the coordinates of point c. With the ellipse equation, curve 03 can be plotted. The ratio of the outlet diameter W1 to the impeller diameter D, W1 / D, is generally in the range of 1.1 to 1.9.

[0092] Finally, the profile of the air guide is rotated and stretched along the central axis to form a curved surface, and then stretched into a solid according to the structural thickness requirements.

[0093] According to the air conditioning equipment and heater provided by this utility model, the air blown out of the air conditioning equipment is diffused, thereby increasing the air supply area. Under the combined action of the heating device and the air guide shroud, a large area of ​​warm air effect can be achieved.
