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, existing products use PTC modules, which are usually located at the front of the fan, resulting in significant air resistance. The airflow is significantly attenuated after passing through the PTC, 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: an outer casing; an air guide shroud disposed inside the outer casing; a fan wheel disposed inside the air guide shroud, the fan wheel rotating to blow air toward the inner wall of the air guide shroud and exhausting it outward from the front side of the outer casing; and a resistance heating device disposed inside the outer casing, the resistance heating device being used to heat the air blown by the fan wheel to the air guide shroud.

[0007] The air conditioning device according to this utility model includes an outer casing, an air guide shroud, a fan, and a resistance heating device. Specifically, the outer casing provides a robust protective shell for the air conditioning device, protecting the internal structure from damage and providing insulation and heat insulation to ensure user safety. Specifically, the air guide shroud, fan, and resistance heating device are all located inside the outer casing. When heating is required, the airflow driven by the fan's rotation flows to the inner wall of the air guide shroud, where it is heated by the resistance heating device and finally discharged outwards through the front of the outer casing. It should be emphasized that the resistance heating device heats the air, including but not limited to direct heating and indirect heating. Direct heating refers to direct heat exchange between the air and the resistance heating device, while indirect heating involves the resistance heating device heating a structure, with the air exchanging heat with the heated structure to achieve air temperature increase. The air guide shroud, located inside the outer casing, guides the air blown by the fan in a specific direction and maintains the stability of the airflow during flow. The design of the inner wall of the air guide shroud affects the efficiency of airflow and the distribution of hot air. The impeller is installed inside the air guide shroud, and its rotation generates airflow. The efficiency of the impeller directly affects the airflow speed and volume, which in turn affects the output of heated air.

[0008] Resistance heating devices are primarily used to heat air blown out by a fan. When energized, the resistance heating device generates heat, which is then transferred to the moving air, raising its temperature. The material, resistance characteristics, and layout design of the resistance heating device all affect its heating efficiency and uniformity.

[0009] Overall, this air conditioning unit achieves efficient airflow and heating through the coordinated operation of its components to provide the desired hot air effect. The outer casing and air guide ensure the direction and stability of the airflow, the impeller provides the necessary airflow, and the resistance heating device provides the heat. The design and material selection of these components directly affect the performance of the unit.

[0010] It should be emphasized that in this solution, the resistance heating device is not directly installed on the front of the entire air conditioning equipment, but is installed between the impeller and the air guide shroud. By using a radially air-discharging impeller, the air will be directed towards the inner wall of the air guide shroud after rotation. After passing through the resistance heating device, the air will be heated, thereby achieving a large volume of warm air effect at the front.

[0011] In some technical solutions, optionally, a heating bracket is also included, which is mounted on the air guide shroud, and a resistance heating device is mounted on the heating bracket.

[0012] In this technical solution, a heating bracket is also provided on the air guide shroud to fix the resistance heating device and keep the heating wire in the proper position. This ensures that the resistance heating device heats up evenly and prevents uneven heat distribution or equipment damage caused by displacement of the resistance heating device. The design of the heating bracket usually takes into account heat resistance and structural stability to withstand high temperatures without deformation.

[0013] The heating wire, mounted on a heating support, primarily converts electrical energy into heat energy to heat the air blown out by the fan and passing through it. The material of the heating wire (such as nickel-chromium alloy) and its resistivity characteristics affect its heating efficiency and lifespan. The arrangement and power design of the heating wire also determine the uniformity and speed of heating.

[0014] In some technical solutions, optionally, the heating bracket is disposed on the inner side wall of the air guide shroud, and heat exchange occurs between the air and the resistance heating device; or the heating bracket is disposed on the outer side wall of the air guide shroud, and the resistance heating device is used to heat the air guide shroud, and heat exchange occurs between the air and the air guide shroud.

[0015] With the heating bracket positioned on the inner wall of the air guide shroud, the rotating impeller draws in cold air and pushes it through the shroud. As the air passes through the resistance heating device on the heating bracket, it is heated and becomes hot air. The hot air is finally exhausted outward from the front of the outer casing, providing the user with the desired hot air. This design of the air conditioning equipment ensures an efficient and uniform air heating process while also guaranteeing the safety and stability of the heating element.

[0016] When the heating bracket is installed on the outer wall of the air guide shroud, the resistance heating device will transfer heat to the air guide shroud, causing the temperature of the air guide shroud to rise. At this time, when the air is blown into the air guide shroud by the fan wheel, it will exchange heat with the high temperature air guide shroud, thereby raising the temperature of the air.

[0017] In some technical solutions, optionally, the resistance heating device is integrally die-cast with the air guide shroud, and the heating tube is used to heat the air guide shroud, and the air exchanges heat with the air guide shroud.

[0018] In this embodiment, the resistance heating device and the air guide cover are integrally die-cast. The resistance heating device can heat the air guide cover, thereby heating the air flowing on the surface, so that the subsequent impeller can run and blow out warm air.

[0019] In some technical solutions, the resistance heating device optionally includes a heating wire and / or a heating tube.

[0020] When the resistance heating device is selected as the heating wire, the position of the heating wire can be fixed by the heating bracket, or the heating wire can be embedded in the air guide shroud. When the resistance heating device is selected as the heating tube, the heating tube can also be embedded in the air guide shroud. The device is manufactured by a one-piece die-casting process.

[0021] In some technical solutions, optionally, the following components are included: a motor bracket located at the air outlet end of the air guide shroud, and the motor bracket is detachably connected to the air guide shroud; a motor mounted on the motor bracket, and the motor's drive shaft is used to drive the fan wheel to rotate.

[0022] In this technical solution, the motor bracket is positioned at the air outlet of the air guide shroud, primarily for supporting and securing the motor. Furthermore, it is detachably connected to the air guide shroud, meaning that motor maintenance and replacement can be more convenient and quick. The design of the motor bracket needs to ensure stable motor installation while facilitating disassembly and maintenance. The motor is mounted on the bracket, and its drive shaft drives the impeller. The motor is the power source for the entire air conditioning system; it transmits kinetic energy to the impeller via the drive shaft, enabling the impeller to rotate and generate airflow. The performance and stability of the motor have a significant impact on the overall efficiency and stability of the equipment.

[0023] The motor drives the impeller via a drive shaft, generating airflow and pushing it towards the air guide shroud. Simultaneously, the heating bracket and resistance heating device heat the air, producing hot air. The synergistic effect of these structures allows the unit to rapidly output warm air to meet user needs. Furthermore, the detachable design of the motor bracket facilitates equipment maintenance and repair.

[0024] In some technical solutions, the motor bracket may optionally include: a fixed plate on which the motor is mounted; and a ring plate located radially outward from the fixed plate, with the ring plate and the fixed plate connected by ribs, and the ring plate being detachably connected to the air guide shroud.

[0025] In this technical solution, the motor bracket consists of a fixed plate, a ring plate, and ribs. Specifically, the fixed plate is the main part of the motor bracket, providing a stable mounting platform for the motor. The motor is mounted on the fixed plate, which needs sufficient strength to support the weight of the motor and the vibrations generated during operation. The ring plate is located radially outward of the fixed plate and mainly serves as a connection structure between the fixed plate and the air guide shroud; that is, the entire motor bracket is connected to the air guide shroud via the ring plate. The ring plate is designed to cooperate with the air guide shroud, allowing the entire motor bracket to be easily disassembled and connected to the air guide shroud.

[0026] In addition, ribs are provided to connect the fixing plate and the ring plate. The design of multiple ribs reduces air resistance during airflow and also provides additional stability and support. The ribs, fixing plate, and ring plate form a relatively stable frame structure, which reduces vibration during motor operation and maintains the structural integrity of the entire support.

[0027] Understandably, this design allows the motor to be securely mounted on the fixed plate, while the ring plate and rib structure create a detachable and stable connection between the motor bracket and the air guide cover. This design not only ensures the stability of the motor during operation but also considers the convenience of maintenance and replacement. When users need to repair or replace the motor, they can easily remove the motor bracket from the air guide cover to perform the necessary operations.

[0028] In some technical solutions, the wind turbine can optionally be a centrifugal wind turbine, with the drive shaft of the motor coinciding with the axis of the wind turbine.

[0029] In this technical solution, a centrifugal fan is used in the air conditioning equipment, with the motor's drive shaft coinciding with the fan's axis. As the centrifugal fan rotates, the centrifugal force of its blades propels air outward from the center of the fan, which is then guided out by a guide shroud. Centrifugal fans are suitable for applications requiring large airflow and high air pressure, and are commonly used in equipment demanding large air volumes or long-distance hot air delivery.

[0030] Furthermore, the alignment of the motor's drive shaft with the wind turbine's shaft ensures that the motor's rotational power is directly and effectively transmitted to the wind turbine, reducing energy loss and improving system efficiency. This direct-shaft connection also allows for more precise alignment between the motor and the wind turbine, helping to reduce vibration and noise, extend equipment lifespan, and simultaneously reduce unnecessary structural design and space occupation, thus improving space utilization.

[0031] The design, which employs a centrifugal impeller and aligns the motor drive shaft with the impeller axis, can achieve efficient airflow and heating. Air is propelled by the centrifugal impeller to generate a high-speed airflow, which is then heated by a resistance heating device. The resulting hot air is guided by an air guide shroud and exhausted from the front of the outer casing.

[0032] In some technical solutions, optionally, the outer casing has an air inlet and an air outlet at both axial ends. The motor drives the impeller to rotate, and air flows into the impeller through the air inlet, passes through the air guide cover, and flows out through the air outlet.

[0033] In this technical solution, the air inlet is the channel through which air enters the outer casing, while the air outlet is the channel through which hot air exits the outer casing. This design allows air to flow smoothly into the impeller for heating, and after passing through the air guide shroud, the heated air is discharged from the equipment, achieving a closed-loop circulation of the entire heating system. The motor drives the impeller to rotate via a drive shaft, thereby generating airflow. This design ensures that the air inside the outer casing can be effectively circulated and heated, improving heating efficiency.

[0034] The design of the outer casing allows for smooth airflow and heating within the entire air conditioning unit, generating hot air. Air enters the casing through the inlet, passes through the impeller and air guide, and is then exhausted through the outlet, providing the user with the desired hot air. This design makes the air conditioning unit suitable for equipment requiring rapid generation and delivery of hot air, such as hair dryers and heat guns, providing a stable and efficient hot air output.

[0035] In some technical solutions, optionally, a gap is formed between the motor bracket and the air guide shroud that communicates with the air outlet; and / or, on the cross-section of the wind turbine, the projected size of the motor bracket is smaller than the maximum projected size of the wind turbine.

[0036] In this technical solution, a gap is formed between the motor bracket and the air guide shroud, communicating with the air outlet. This ensures that hot air can flow smoothly from the air guide shroud through the gap, guaranteeing unimpeded hot air discharge. Simultaneously, this design helps reduce wind resistance, improves the efficiency of the entire system, and ensures stable hot air output. Furthermore, by limiting the projected size of the motor bracket to be smaller than the maximum projected size of the impeller, collisions or friction between the motor bracket and the moving parts of the impeller can be avoided, thereby reducing noise and wear. This design ensures the stability and safety of the air conditioning equipment during operation.

[0037] Understandably, the above design contributes to the stable operation of the air conditioning equipment and the efficient output of hot air. The gap connecting to the air outlet allows hot air to flow smoothly out of the air guide shroud, and the projected size of the motor bracket is smaller than the maximum projected size of the impeller, avoiding unnecessary friction and collisions. These designs are all aimed at ensuring the safe, efficient, and stable operation of the entire air conditioning system.

[0038] In some technical solutions, the heating bracket and the air guide shroud can be optionally molded as a single unit.

[0039] In this technical solution, the one-piece molding design means there are no seams between the heating bracket and the air guide shroud, providing greater structural stability and mechanical strength. This design helps reduce wear caused by vibration or long-term use, thereby improving the equipment's durability. Furthermore, the one-piece molding reduces the number of steps and parts required in the assembly process, which not only lowers production costs but also increases production efficiency. Simultaneously, it reduces the risk of failure due to poor assembly.

[0040] Of course, since the heating bracket and air guide cover are molded as a single piece, cleaning and maintenance are much easier. The absence of gaps and seams means that dust and dirt don't easily accumulate, and it's also easier to clean.

[0041] In some technical solutions, the outer casing may optionally include: a casing body, and a front mesh cover and a rear mesh cover detachably connected to the casing body, wherein the front mesh cover, casing body, and rear mesh cover are connected to form a receiving cavity for accommodating the resistance heating device, the air guide cover, the impeller, and the motor.

[0042] In this technical solution, the outer casing includes a cover body and front and rear mesh covers detachably connected to it. These together form a cavity that accommodates the resistance heating device, the air guide shroud, and the impeller. The detachable design of the cover body, front mesh cover, and rear mesh cover facilitates 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.

[0043] The cavity formed by the connection of the cover, front mesh cover and rear mesh cover provides suitable space to house the resistance heating device, air guide cover, impeller and motor, so that these internal components can be effectively installed and fixed.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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

[0057] 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.

[0058] 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.

[0059] The following reference Figures 1 to 5 Some embodiments of the present invention are described below.

[0060] like Figure 1 and Figure 2 As shown, this embodiment proposes an air conditioning device 100, including a housing 102, an air guide 106, a fan 108, and a resistance heating device 104. 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. Specifically, the air guide 106, fan 108, and resistance heating device 104 are all located inside the housing 102. When heating is required, the airflow driven by the rotation of the fan 108 flows to the inner wall of the air guide 106, where it is heated by the resistance heating device 104 and finally discharged outwards through the front of the housing 102. It should be emphasized that the heating of air by the resistance heating device includes, but is not limited to, direct heating and indirect heating. Direct heating means that the air directly exchanges heat with the resistance heating device, while indirect heating means that the resistance heating device heats a structure, and the air exchanges heat with the heated structure, thereby raising the air temperature. The air guide shroud 106, located inside the outer casing 102, guides the air blown out by the impeller 108 in a specific direction and maintains the stability of the airflow during the flow. The design of the inner wall of the air guide shroud 106 affects the efficiency of airflow and the distribution of hot air. The impeller 108 is installed inside the air guide shroud 106, and its rotation generates airflow. The efficiency of the impeller 108 directly affects the airflow speed and volume, and thus the output of heated air.

[0061] The resistance heating device 104 is mainly used to heat the air blown out by the impeller 108. When energized, the resistance heating device 104 generates heat, which is then transferred to the moving air, raising its temperature. The material, resistance characteristics, and layout design of the resistance heating device 104 all affect the heating efficiency and uniformity.

[0062] Overall, this air conditioning device 100 achieves effective airflow and heating through the coordinated operation of its components to provide the desired hot air effect for the user. The outer casing 102 and the air guide shroud 106 ensure the direction and stability of the airflow, the impeller 108 provides the necessary airflow, and the resistance heating device 104 is responsible for providing heat. The design and material selection of these components have a direct impact on the performance of the unit.

[0063] It should be emphasized that in this solution, the resistance heating device 104 is not directly installed on the front side of the entire air conditioning equipment 100, but is installed between the impeller 108 and the air guide shroud 106. By using the radially air-discharging impeller 108, after rotation, the air will be discharged towards the inner wall of the air guide shroud 106. After passing through the resistance heating device 104, the air will be heated, thereby achieving a large volume of warm air effect at the front.

[0064] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the resistance heating device is a heating wire 1044. A heating bracket 1042 is also provided on the air guide shroud 106 to fix the heating wire 1044 and keep it in a proper position. This ensures that the heating wire 1044 heats up evenly and prevents uneven heat distribution or equipment damage caused by displacement of the heating wire 1044. The design of the heating bracket 1042 typically takes into account heat resistance and structural stability to withstand high temperatures without deformation.

[0065] It should be added that heat exchange occurs between the air and the heating wire.

[0066] The heating wire 1044 is mounted on the heating bracket 1042. Its main function is to convert electrical energy into heat energy to heat the air blown out by the fan 108 and passing through the heating wire 1044. The material (such as nickel-chromium alloy) and resistance characteristics of the heating wire 1044 affect its heating efficiency and lifespan. The arrangement and power design of the heating wire 1044 also determine the uniformity and speed of heating.

[0067] When the impeller 108 rotates, it draws in cold air and pushes it towards the air guide shroud 106. As the air passes through the resistance heating device 104 on the heating bracket 1042, it is heated and becomes hot air. The hot air is finally exhausted outward from the front of the outer casing 102, providing the user with the desired hot air. This design of the air conditioning device 100 makes the air heating process efficient and uniform, while also ensuring the safety and stability of the heating element.

[0068] In another embodiment, such as Figure 5 As shown, the resistance heating device is tubular, specifically a heating tube 1052 integrally die-cast with the air guide shroud. Under the action of the heating tube 1052, the air guide shroud can be heated, thereby heating the air flowing on the surface, so that the subsequent impeller can run and blow out warm air.

[0069] It is understandable that when the resistance heating device is selected as the heating wire, the position of the heating wire can be fixed by the heating bracket, and the heating wire can also be embedded in the air guide shroud. When the resistance heating device is selected as the heating tube, the heating tube can also be embedded in the air guide shroud, and it can be manufactured by a one-piece die-casting process.

[0070] In some embodiments, optionally, the motor bracket 116 is positioned at the air outlet end of the air guide shroud 106, primarily for supporting and fixing the motor 110. Furthermore, it is detachably connected to the air guide shroud 106, meaning that maintenance and replacement of the motor 110 can be more convenient and quick. The design of the motor bracket 116 needs to ensure the stable installation of the motor 110 while facilitating disassembly and maintenance. Of course, the motor 110 is mounted on the motor bracket 116, and its drive shaft 1102 is used to drive the fan wheel 108 to rotate. The motor 110 is the power source for the entire air conditioning device 100; it transmits kinetic energy to the fan wheel 108 through the drive shaft 1102, enabling the fan wheel 108 to rotate and generate airflow. The performance and stability of the motor 110 have a significant impact on the overall operating efficiency and stability of the device.

[0071] The motor 110 drives the impeller 108 to rotate via the drive shaft 1102, generating airflow and pushing it towards the air guide shroud 106. Simultaneously, the heating bracket 1042 and the resistance heating device 104 heat the air, producing hot air. The synergistic effect of these structures allows the unit to rapidly output warm air to meet user needs. Furthermore, the detachable design of the motor bracket 116 facilitates equipment maintenance and repair.

[0072] In some embodiments, the motor bracket 116 is optionally composed of a fixing plate 1162, an annular plate 1164, and ribs 1166. Specifically, the fixing plate 1162 is the main part of the motor bracket 116, providing a stable mounting platform for the motor 110. The motor 110 is mounted on the fixing plate 1162, which needs to be strong enough to support the weight of the motor 110 and the vibrations generated during operation. The annular plate 1164 is located radially outward of the fixing plate 1162, mainly serving as a connection structure between the fixing plate 1162 and the air guide shroud 106, i.e., the entire motor bracket 116 is connected to the air guide shroud 106 through the annular plate 1164. The annular plate 1164 is designed to cooperate with the air guide shroud 106, allowing the entire motor bracket 116 to be easily detached and connected to the air guide shroud 106.

[0073] In addition, ribs 1166 are provided to connect the fixing plate 1162 and the ring plate 1164. The design of multiple ribs 1166 can reduce air resistance during air outlet and also provide additional stability and support. Through the ribs 1166, the fixing plate 1162 and the ring plate 1164 form a relatively stable frame structure, which can reduce vibration when the motor 110 is running and maintain the structural integrity of the entire bracket.

[0074] Understandably, this design allows the motor 110 to be securely mounted on the fixed plate 1162, while the structure of the ring plate 1164 and the ribs 1166 forms a detachable and stable connection between the motor bracket 116 and the air guide shroud 106. This design not only ensures the stability of the motor 110 during operation but also considers the convenience of maintenance and replacement. When users need to repair or replace the motor 110, they can easily remove the motor bracket 116 from the air guide shroud 106 to perform the corresponding operations.

[0075] In some embodiments, optionally, by using a centrifugal impeller in the air conditioning device 100, and with the drive shaft 1102 of the motor 110 coinciding with the axis of the impeller 108, the centrifugal impeller, when rotating, uses the centrifugal force of its blades to throw air outward from the center of the impeller 108, and then guides the hot air out through the air guide shroud 106. Centrifugal impellers are suitable for applications requiring large airflow and high air pressure, and are commonly used in equipment that requires large air volume or long-distance hot air delivery.

[0076] Furthermore, the coincidence design of the drive shaft 1102 of the motor 110 and the axis of the impeller 108 ensures that the rotational power of the motor 110 is directly and effectively transmitted to the impeller 108, reducing energy loss and improving system efficiency. This direct shaft connection also makes the alignment of the motor 110 and the impeller 108 more precise, which helps to reduce vibration and noise, extend the service life of the equipment, and at the same time reduce unnecessary structural design and space occupation, improving space utilization.

[0077] It is understandable that by using a centrifugal impeller and aligning the drive shaft 1102 of the motor with the axis of the impeller 108, efficient airflow and heating can be achieved. The air generates a high-speed airflow under the action of the centrifugal impeller, and is then heated by the resistance heating device 104. The resulting hot air is then guided by the air guide shroud 106 and discharged from the front of the outer casing 102.

[0078] In some embodiments, the air inlet 1032 is optionally the channel for air to enter the outer casing 102, while the air outlet 1034 is the channel for hot air to exit the outer casing 102. This design allows air to flow smoothly into the impeller 108 for heating, and after passing through the air guide shroud 106, the heated hot air is discharged from the device, realizing a closed-loop cycle for the entire heating system. The motor 110 drives the impeller 108 to rotate via the drive shaft 1102, thereby generating airflow. This design ensures that the air inside the outer casing 102 can be effectively circulated and heated, improving heating efficiency.

[0079] The design of the outer casing 102 allows for smooth airflow and heating within the entire air conditioning unit 100, thereby generating hot air. Air enters the outer casing 102 through the air inlet 1032, passes through the impeller 108 and the air guide 106, and the heated air is then discharged outward through the air outlet 1034, providing the user with the required hot air. This design of the air conditioning unit 100 is suitable for equipment requiring rapid generation and delivery of hot air, such as hair dryers and heat guns, providing stable and efficient hot air output.

[0080] In some embodiments, optionally, a gap communicating with the air outlet 1034 is formed between the motor bracket 116 and the air guide shroud 106, thereby ensuring that hot air can flow smoothly from the air guide shroud 106 through the gap, guaranteeing the smooth discharge of hot air. Simultaneously, this design also helps reduce wind resistance, improves the efficiency of the entire system, and ensures stable hot air output. Furthermore, by limiting the projected size of the motor bracket 116 to be smaller than the maximum projected size of the impeller 108, collisions or friction between parts of the motor bracket 116 and the moving parts of the impeller 108 can be avoided, thereby reducing noise and wear. This design ensures the stability and safety of the air conditioning device 100 during operation.

[0081] Understandably, the above design contributes to the stable operation of the air conditioning unit 100 and the efficient output of hot air. Through the gap connecting to the air outlet 1034, hot air can flow smoothly out of the air guide shroud 106, and the projected size of the motor bracket 116 is smaller than the maximum projected size of the impeller 108, thus avoiding unnecessary friction and collisions. These designs are all aimed at ensuring the safe, efficient, and stable operation of the entire air conditioning unit 100.

[0082] In some embodiments, the heating bracket 1042 and the air guide shroud 106 are optionally integrally formed. This integral design means there are no seams between the heating bracket 1042 and the air guide shroud 106, providing greater structural stability and mechanical strength. This design helps reduce wear caused by vibration or prolonged use, thereby improving the durability of the equipment. Furthermore, the integrally formed components reduce the number of steps and parts required in the assembly process, which not only reduces production costs but also improves production efficiency. Simultaneously, it reduces the risk of failure due to poor assembly.

[0083] Of course, since the heating bracket 1042 and the air guide shroud 106 are molded as a single piece, cleaning and maintenance are much easier. The absence of gaps and seams means that dust and dirt are less likely to accumulate, and cleaning is also easier.

[0084] The outer casing 102 includes a casing 1026 and a front mesh cover 1022 and a rear mesh cover 1024 detachably connected thereto. These components together form a cavity that accommodates the resistance heating device 104, the air guide shroud 106, and the impeller 108. The detachable design of the casing 1026, the front mesh cover 1022, and the rear mesh cover 1024 facilitates 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.

[0085] The cavity formed by the connection of the cover 1026, the front mesh cover 1022 and the rear mesh cover 1024 provides suitable space to house the resistance 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.

[0086] 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.

[0087] 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, namely the cover body 1026, 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.

[0088] This application proposes another embodiment of the heater 200, such as... Figure 4 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.

[0089] 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.

[0090] In one specific embodiment, a side-wall heated air blower 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), and heating wires. The air guide 106 is made of heat-resistant material, and the heating wires are mounted inside the air guide 106 via a fixed bracket. When powered on, the heating wires heat up. Air is accelerated by the centrifugal fan and thrown against the wall of the air guide 106, then flows out along the wall, directly exchanging heat with the heating wires, increasing its temperature. Finally, after being rectified by the front grille, the air is blown out.

[0091] In this system, the air guide shroud acts as a guide, and the heating wire is fixed to the inner surface of the shroud. During the flow of air along the wall, it directly exchanges heat with the heating wire without adding additional airflow resistance, thus greatly increasing the overall airflow velocity. In contrast, traditional fan heaters use a PTC heater placed in front of the fan, which results in very high airflow resistance and very low airflow.

[0092] When the impeller rotates, it does work on the air, which gains kinetic energy and moves in a spiral motion, moving forward along the axis of the guide vane (i.e., the air guide vane 106). Simultaneously, because the guide vane is heat-generating, the air is gradually heated as it moves forward. The air guide vane 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 Transmitter) placed in front of the fan, resulting in very high airflow resistance and minimal air output.

[0093] To generate heat for the fairing, a resistance heating scheme can be used, which can be divided into heating wire and die-cast heating tube schemes.

[0094] Heating wire solution: The heating wire is fixed in the internal space of the guide shroud by the mounting bracket. The air thrown off by the impeller is heated by the heating wire during the movement of the guide shroud.

[0095] Die-cast heating element solution: The air guide and the heating element are combined into one through a die-casting process. The heating element heats the air guide, which in turn heats the air flowing on the surface.

[0096] The air conditioning equipment and heater provided by this utility model can achieve a large air volume heating effect at the front.
