Description

[0001] This application claims priority to Chinese Patent Application No. 202410244257.5, filed on March 4, 2024, entitled "Air Conditioning Equipment and Heater", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of heater technology, specifically to an air conditioning device and a heater. Background Technology

[0003] Currently, some users typically use fan heaters for warmth. In related technologies, existing products use PTC modules, which employ resistance heating to heat a small area, resulting in poor heating performance and affecting the heating experience. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] In view of the above, an embodiment of the first aspect of the present invention provides an air conditioning device.

[0006] A second aspect of this utility model provides a heater.

[0007] 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; 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; and a rib, disposed on the inner side wall of the air guide shroud.

[0008] The air conditioning device proposed in this utility model mainly includes a heating device, an air guide shroud, and an airflow regulating component. 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 the heating device raises 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 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. The specific shape design should facilitate uniform airflow distribution and heat exchange efficiency. The impeller is located inside the air guide shroud, and its rotation generates a strong airflow. This airflow is heated as it passes through the heated air guide shroud and is finally discharged from the front of the unit.

[0009] It is important to emphasize that raised ribs are provided on the inner side of the air guide shroud to increase its surface area, thereby improving heat exchange efficiency. Air conditioning equipment primarily converts electrical energy into heat and mechanical energy to generate hot air. In this design, by adjusting the relative positions of the motor and impeller, and simultaneously enhancing the structure of the air guide shroud, air is blown towards the shroud by the impeller. The shroud, heated by the heating device, increases the temperature of the air blowing towards it. Furthermore, the structural features of the air guide shroud itself direct airflow to the outside of the air conditioning equipment, thus providing warm air with a higher wind speed.

[0010] 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.

[0011] In some technical solutions, optionally, there are multiple ribs, some of which extend along the same spiral line, and there are intervals between multiple ribs corresponding to the same spiral line.

[0012] In this technical solution, the raised ribs increase the surface area of ​​the inner wall of the air guide shroud, thereby increasing the contact area between the passing air and the air guide shroud and improving the heat exchange efficiency.

[0013] By setting spaced ribs along the same spiral line, airflow can be effectively guided and its resistance reduced, which helps to improve the rotational efficiency of the wind turbine and its overall aerodynamic performance.

[0014] The number of ribs needs to be sufficient to ensure adequate heat exchange area, but not so many that they excessively increase airflow resistance. Furthermore, the spacing between the ribs needs careful design to maintain good aerodynamic characteristics and heat exchange efficiency. Too small a spacing may increase airflow resistance, while too large a spacing may reduce heat exchange efficiency.

[0015] Some of the raised ribs extend along the same spiral line. This arrangement helps to form a continuous airflow path, thereby achieving a better guiding effect.

[0016] In summary, the raised rib design not only improves heat exchange efficiency but also optimizes airflow guidance and dynamic performance. By adjusting the number, spacing, and arrangement of the raised ribs, the performance of the entire system can be further adjusted and optimized.

[0017] In some technical solutions, optionally, there are multiple ribs, with each rib corresponding to a spiral line.

[0018] In this technical solution, there are multiple spiral lines, each corresponding to a rib, which can form multiple heat exchange channels. This design can make the overall heat exchange more uniform and the airflow dynamic performance better.

[0019] In some technical solutions, the number of protruding ribs may optionally be one.

[0020] In this technical solution, only one rib is provided, resulting in a prominent raised spiral line inside the air guide shroud. Its function is to improve heat exchange efficiency and guide airflow without significantly increasing wind resistance. Furthermore, this rib corresponds to a spiral line, and the shape and path of the rib are spiral-shaped, which helps to form a stable airflow rotation, thereby improving heat transfer and aerodynamic performance.

[0021] In some technical solutions, the ribs and the air guide cover can be integrally stamped.

[0022] In this technical solution, the one-piece molded ribs and air guide cover structure have high strength because there are no potential weaknesses such as welding or bolt connections. In addition, the one-piece stamping process simplifies the production process, reduces assembly steps, and improves manufacturing efficiency and product consistency.

[0023] In some technical solutions, optionally, the raised rib extends along a spiral line, the pitch of the spiral line is 10mm to 200mm, and the spiral angle of the spiral line is 15° to 80°.

[0024] In this technical solution, the raised ribs extend along the spiral line. Their function is to guide the airflow to rotate without significantly increasing wind resistance, thereby enhancing the contact between the airflow and the inner wall of the air guide shroud and further improving the heating effect and aerodynamic performance.

[0025] By separately limiting the pitch and helix angle of the spiral, with the pitch set within the range of 10mm to 200mm, the most suitable pitch can be selected according to specific needs and space constraints to achieve optimal heat exchange and airflow guidance. The helix angle ranges from 15° to 80°, and the selection within this range can affect the degree of airflow rotation and speed, thereby affecting heat transfer efficiency and aerodynamic performance.

[0026] In some technical solutions, optionally, the height of the rib is 3mm to 6mm, the width of the rib is 4mm to 8mm, and the spacing between two adjacent ribs in the axial direction of the air guide is 5mm to 12mm.

[0027] In this technical solution, the height of the raised ribs ranges from 3mm to 6mm, and the width ranges from 4mm to 8mm. The selection within these ranges can affect the heat transfer area of ​​the raised ribs and the degree of interference with airflow, thus affecting the overall heat exchange efficiency and aerodynamic performance. Furthermore, the spacing between two adjacent raised ribs in the axial direction of the air guide shroud ranges from 5mm to 12mm. This selection can affect the airflow pattern and resistance, thereby influencing the overall aerodynamic performance and heat exchange efficiency.

[0028] It should be added that two adjacent ribs can be on the same helix or on different helixes.

[0029] In some technical solutions, optionally, there is a gap between the rib and the impeller. The outer circumferential surface of the impeller includes a connected closed part and an air outlet. When the impeller rotates, air is blown from the air outlet to the air guide shroud. In the axial direction of the impeller, the first minimum gap between the rib and the closed part is 3mm to 12mm, and in the radial direction of the impeller, the second minimum gap between the rib and the closed part is 2mm to 10mm.

[0030] In this technical solution, the first minimum axial clearance ranges from 3mm to 12mm. The selection within this range affects the airflow and resistance between the ribs and the impeller, thus influencing the overall aerodynamic performance and heat exchange efficiency. It is understandable that a reasonable axial clearance ensures the normal rotation of the impeller while preventing the ribs from interfering with its movement, maintaining the system's stability and efficiency.

[0031] The second minimum radial clearance ranges from 2mm to 10mm. The choice within this range can also affect airflow and resistance, thus impacting overall aerodynamic performance and heat exchange efficiency. A suitable radial clearance ensures full utilization of the space between the ribs and the impeller's enclosed portion, guaranteeing both normal impeller operation and maximizing heat exchange efficiency.

[0032] It should be added that the selection of these clearance parameters needs to take into account factors such as space utilization in the axial and radial directions, airflow dynamics characteristics and resistance, in order to achieve the best heat exchange efficiency and aerodynamic performance.

[0033] A well-designed clearance can balance the operational stability of the wind turbine, the airflow between the ribs and the wind turbine, and the resistance, thereby achieving the best performance of the overall design.

[0034] In some technical solutions, optionally, the airflow regulating component specifically includes: a fan wheel, disposed inside the air guide shroud, the fan wheel rotating to discharge air toward the inner wall of the air guide shroud and outward from the front side of the air conditioning device; and a motor, the drive shaft of the motor passing through the fan wheel, the drive shaft being used to drive the fan wheel to rotate.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] Alternatively, an electric heating wire can be used as a heating device, which can quickly generate heat. The heat-conducting air guide shroud helps to conduct heat quickly, improving heating efficiency.

[0041] The air guide shroud is made of a thermally conductive material, and the heating element is mounted on it. This thermal conductivity facilitates the rapid conduction and exhaust of heated air, thereby improving the utilization rate of hot air and ensuring a stable output. By placing the heating element on the air guide shroud, heat transfer from the heating element to other components is reduced, lowering the equipment temperature and improving operational safety.

[0042] 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 receiving cavity for accommodating the heating device, the air guide cover, the impeller and the motor; wherein, the front mesh cover is provided with a first bearing for the drive shaft to pass through.

[0043] In this technical solution, the outer casing provides a robust protective shell for the air conditioning equipment. It not only protects the internal structure from damage but also provides heat insulation and electrical insulation to ensure user safety. The casing includes detachable front and rear mesh covers that connect to form a cavity housing the heating element, air guide, impeller, and motor. The front mesh cover features a first bearing through which the drive shaft passes. The detachable design of the front and rear mesh covers facilitates maintenance and cleaning of the internal components, making repairs more convenient. This is highly beneficial for the routine maintenance and upkeep of the equipment.

[0044] 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.

[0045] It should be added that the front grille has a first bearing through which the drive shaft passes, which helps to support and fix the drive shaft, ensuring stable operation of the drive shaft and reducing vibration and friction caused by the movement of the drive shaft.

[0046] 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.

[0047] In some technical solutions, optionally, there are multiple ribs, each of which extends along the front-rear direction of the air guide shroud.

[0048] In this technical solution, by setting multiple ribs and extending them along the front-back direction of the air guide shroud, the airflow can be guided. The ribs extend in the front-back direction, and can be axially inclined or even extend directly along the axial direction.

[0049] 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.

[0050] The heater according to this utility model includes an air conditioning unit. Optionally, it can be equipped with a base bracket that is detachably connected to the air conditioning unit. This design facilitates the assembly and disassembly of the equipment, making it 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 equipment.

[0051] 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.

[0052] 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

[0061] 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.

[0062] 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.

[0063] The following reference Figures 1 to 5 Some embodiments of the present invention are described below.

[0064] 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 107 disposed within the housing 102. Specifically, the airflow regulating assembly includes a fan 108 and a motor 110. 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 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 ceramic, 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. The specific shape design should facilitate uniform airflow distribution and heat exchange efficiency. The impeller 108 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 is eventually discharged from the front of the machine head.

[0065] It should be added that, for the entire air conditioning unit, the front side is the air outlet side of the outer casing, and the rear side is the air inlet side. The front-to-back direction of the air conditioning unit is the same as the front-to-back direction of the air guide shroud. Specifically, as shown below... Figure 2 The direction indicated by the middle arrow.

[0066] It needs to be emphasized that, such as Figure 3As shown, a raised rib 120 is provided on the inner side of the air guide shroud 106. The raised rib 120 extends along a spiral line. Its function is to increase the surface area of ​​the air guide shroud 106 without significantly increasing the wind resistance, thereby improving the heat exchange efficiency. In addition, the spiral-shaped raised rib 120 can also guide the airflow to rotate, enhance the contact between the airflow and the inner wall of the air guide shroud 106, and further improve the heating effect and aerodynamic performance.

[0067] 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 110 and the impeller 108, 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 108. 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.

[0068] It should be added that the type of motor 110 can be a DC or AC motor 110, or even a brushless motor 110 to improve efficiency and reduce maintenance; the power and speed of the motor 110 must be matched with the design of the impeller 108; and the heat dissipation design of the motor 110 must ensure that it will not overheat during long-term operation.

[0069] In some embodiments, the ribs 120 may increase the surface area of ​​the inner wall of the air guide shroud 106, thereby increasing the contact area between the passing air and the air guide shroud 106 and thus improving the heat exchange efficiency.

[0070] By setting spaced ribs 120 on the same spiral line, the airflow can be effectively guided and the airflow resistance can be reduced when passing through, which helps to improve the rotational efficiency and overall aerodynamic performance of the impeller 108.

[0071] The number of ribs 120 needs to be sufficient to ensure adequate heat exchange area, but not so many that they excessively increase airflow resistance. At the same time, the spacing between the ribs 120 needs to be carefully designed to maintain good aerodynamic characteristics and heat exchange efficiency. Too small a spacing may lead to increased airflow resistance, while too large a spacing may reduce heat exchange efficiency.

[0072] Some of the raised ribs 120 extend along the same spiral line. This arrangement helps to form a continuous airflow path, thereby achieving a better guiding effect.

[0073] In summary, the design of the raised ribs 120 not only improves heat exchange efficiency but also optimizes airflow guidance and dynamic performance. By adjusting the number, spacing, and arrangement of the raised ribs 120, the performance of the entire system can be further adjusted and optimized.

[0074] In some embodiments, there may be multiple spiral lines, each corresponding to a rib 120, which can form multiple heat exchange channels. This design can make the overall heat exchange more uniform and the airflow dynamic performance better.

[0075] In some embodiments, optionally, only one rib 120 is provided, resulting in a prominent raised spiral line inside the air guide shroud 106. Its function is to improve heat exchange efficiency and guide airflow without significantly increasing wind resistance. Furthermore, the rib 120 is correspondingly provided to a spiral line, and the shape and path of the rib 120 are spiral-shaped, which helps to form a stable airflow rotation, thereby improving heat transfer and aerodynamic performance.

[0076] In some embodiments, the integrally formed rib 120 and air guide shroud 106 have high structural strength because there are no potential weaknesses such as welding or bolted connections. Furthermore, the integral stamping process simplifies the production process, reduces assembly steps, and improves manufacturing efficiency and product consistency.

[0077] In some embodiments, the pitch and helix angle of the spiral can be optionally limited separately. Specifically, the pitch can be set within a range of 10mm to 200mm, allowing for the selection of the most suitable pitch based on specific needs and space constraints to achieve optimal heat exchange and airflow guidance. The helix angle ranges from 15° to 80°, and selection within this range can affect the degree of airflow rotation and speed, thereby influencing heat transfer efficiency and aerodynamic performance.

[0078] In some embodiments, optionally, such as Figure 4 As shown, the height of the rib 120 ranges from 3mm to 6mm, and the width ranges from 4mm to 8mm. The selection within these ranges can affect the heat transfer area of ​​the rib 120 and the degree of interference with airflow, thus affecting the overall heat exchange efficiency and aerodynamic performance. The spacing between two adjacent ribs 120 ranges from 5mm to 12mm. The selection within this range can affect the airflow pattern and resistance, further affecting the overall aerodynamic performance and heat exchange efficiency.

[0079] In some embodiments, optionally, such as Figure 4 As shown, the outer circumferential surface of the wind turbine includes a connected closed portion 1082 and an air outlet portion 1084. When the wind turbine rotates, air is blown from the air outlet portion 1084 to the air guide cover. In the axial direction of the wind turbine, the first minimum gap between the rib and the closed portion 1082 is 3mm to 12mm, and in the radial direction of the wind turbine, the second minimum gap between the rib and the closed portion 1082 is 2mm to 10mm.

[0080] The minimum axial clearance ranges from 3mm to 12mm. The selection within this range affects the airflow and resistance between the rib 120 and the impeller 108, thus influencing the overall aerodynamic performance and heat exchange efficiency. It is understandable that a reasonable axial clearance ensures the normal rotation of the impeller 108 while preventing the rib 120 from interfering with its movement, maintaining system stability and efficiency.

[0081] The second minimum radial clearance ranges from 2mm to 10mm. The choice within this range can also affect the airflow and resistance, thereby affecting the overall aerodynamic performance and heat exchange efficiency. A reasonable radial clearance can ensure that the space between the rib 120 and the impeller 108 is fully utilized, which can both ensure the normal operation of the impeller 108 and maximize the heat exchange efficiency.

[0082] It should be added that the selection of these clearance parameters needs to take into account factors such as space utilization in the axial and radial directions, airflow dynamics characteristics and resistance, in order to achieve the best heat exchange efficiency and aerodynamic performance.

[0083] A reasonable gap design can balance the operational stability of the impeller 108, the airflow between the rib 120 and the impeller 108, and the resistance, thereby achieving the best performance of the overall design scheme.

[0084] 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. 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 and extend its service life.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] In some embodiments, an electric heating wire is optionally used as the heating device 104, which can quickly generate heat, and the heat-conducting air guide shroud 106 helps to conduct heat quickly.

[0091] The air guide shroud 106 is made of a thermally conductive material, and the heating device 104 is mounted on it. The thermally conductive material of the air guide shroud 106 facilitates the rapid conduction and exhaust of heated air, thereby improving the utilization rate of hot air and ensuring stable hot air output. By mounting the heating device 104 on the air guide shroud 106, heat conduction from the heating device 104 to other components is reduced, lowering the equipment temperature and improving operational safety.

[0092] 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.

[0093] 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.

[0094] In one specific embodiment, a sidewall-heated air heater 200 structure is proposed. The overall structure includes a motor 110, a front grille 1022, a fan 108, a shell (i.e., shell cover 102), a heating element (i.e., air guide 106), a heating element bracket (i.e., heat insulation bracket 1062), a coil disc bracket (i.e., heating bracket 1042), and an air duct (i.e., air duct structure 114). The overall solution 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 sidewall of the power unit is made of magnetically conductive metal parts and is heated by electromagnetic induction. During operation, the airflow is heated by passing through the heated sidewall, thereby realizing the warm air function.

[0095] 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.

[0096] The air duct structure 114 serves two main purposes: first, it forms a heat dissipation air duct; second, it serves to secure and support the structure. The fixing of other structural components is relatively conventional: the impeller is fixed to the motor, the motor is fixed to the outer casing, and finally, the front grille is fixed to the outer casing, forming a complete machine.

[0097] 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 deflector. Simultaneously, because the deflector is heated, the air is gradually heated as it moves forward. The deflector in this system serves two purposes: first, to guide the airflow, and second, to heat it, without adding additional duct resistance, thus significantly increasing the overall airflow velocity. In contrast, traditional warm air heaters use a PTC (Power Transmitter Charge) placed in front of the fan, resulting in very high airflow resistance and minimal air output.

[0098] To increase the heating area of ​​the deflector, protruding structures, such as helical ribs (i.e., raised ribs), can be added to the surface of the deflector. There can be one or more helical ribs, and the direction of the helix is ​​consistent with the rotation direction of the impeller, which can be determined using the right-hand rule. The parameters of the helical baseline include the pitch S1 and the inlet helix angle α. The pitch S1 ranges from 10mm to 200mm, and the inlet helix angle α is determined by the impeller speed, generally ranging from 15° to 80°.

[0099] The main parameters of the ribs include the rib height H (range 3mm~6mm), width W (range 4mm~8mm), and spacing L between ribs (range 5mm~12mm). Since the wind deflector is made of ferromagnetic metal, the ribs can be formed by stamping. To ensure that the stamped ribs do not interfere with the impeller and do not affect aerodynamic performance, the minimum axial distance S2 between the ribs and the impeller must satisfy: 3mm≤S2≤12mm; the minimum radial distance S3 between the ribs and the impeller must satisfy: 2mm≤S3≤10mm.

[0100] According to the air conditioning equipment and heater provided by this utility model, the protruding ribs on the air guide cover can significantly improve the heating effect and aerodynamic performance.
