[0001] The present invention relates to the technical field of air heaters, and in particular to an air conditioning device, an air heater and a control method. Background Art

[0002] At present, in the relevant technology, some users usually use heaters for heating. However, the existing products use PTC (Positive Temperature Coefficient) modules, and the PTC modules are usually located in front of the fan, resulting in large wind resistance. After the air flows through the PTC, it will produce large attenuation, resulting in a low final air outlet speed, affecting the heating experience. Summary of the Invention

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

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

[0005] An embodiment of a second aspect of the present invention provides a fan heater.

[0006] An embodiment of the third aspect of the present invention provides a control method.

[0007] In order to achieve the above-mentioned purpose, an embodiment of the first aspect of the present invention provides an air conditioning device, including: an outer shell cover; a heating device, which is arranged on the inner side of the outer shell cover; an air guide cover, which is arranged corresponding to the heating device, and the heating device is used to heat the air guide cover; an air flow adjustment component, at least part of the air flow adjustment component is arranged inside the outer shell cover, the air flow adjustment component is used to discharge air toward the inner wall surface of the air guide cover, and the air guide cover is used to guide the air.

[0008] The air conditioning equipment proposed in accordance with the present invention mainly includes an outer shell and a heating device, an air guide cover, and an air flow adjustment component arranged in the outer shell. Specifically, the outer shell provides a sturdy protective shell for the air conditioning equipment, which not only protects the internal structure from damage, but also can be made of materials that play a role of heat insulation and insulation to ensure the safety of users when using it. The heating device is the core of the air conditioning equipment and is responsible for converting electrical energy into thermal energy. The heating device is arranged corresponding to the air guide cover, and the heating device can increase the temperature of the air guide cover. Specifically, the heating device can be composed of a high-temperature resistant resistance wire, or it can use more efficient materials such as PTC ceramics, or even an electromagnetic coil. Part or all of the structure in the air flow adjustment component is located in the outer shell. The air flow adjustment component can generate strong airflow when it is in operation. These airflows are heated when passing through the heated air guide cover, and can change the flow direction under the guiding effect of the air guide cover, and finally be discharged from the front side of the air conditioning equipment.

[0009] Optionally, part or all of the airflow adjustment components are located within the air guide cover.

[0010] Air conditioning equipment can mainly convert electrical energy into thermal energy and mechanical energy to generate hot air.

[0011] In some technical solutions, optionally, the airflow adjustment component specifically includes: a wind wheel, which is arranged inside the air guide cover, and the wind wheel rotates to blow air toward the inner wall surface of the air guide cover. The air is heated by the air guide cover and discharged outward from the front side of the outer cover; a motor, which is transmission-connected to the wind wheel.

[0012] In this technical solution, the air flow adjustment component includes a wind wheel and a motor. By adjusting the relative positions of the motor and the wind wheel and adding the structure of the wind guide cover, the air will be blown towards the wind guide cover under the action of the wind wheel. The wind guide cover is heated up under the action of the electromagnetic heating device, which can increase the temperature of the air blown to the wind guide cover. At the same time, the air can be diverted to the outside of the air conditioning equipment through the structural characteristics of the wind guide cover itself, thereby providing warm air with a higher wind speed. The wind guide cover realizes the dual functions of heating and diversion, and can reduce the wind resistance caused by the heating process of the existing technology.

[0013] It should be noted that by providing a motor with its drive shaft extending into and engaging the wind rotor, the drive shaft can be controlled to rotate the wind rotor while the motor is running. It can be understood that the motor provides the necessary power, converting electrical energy into mechanical energy, enabling the wind rotor to rotate and generate airflow. The motor design must ensure sufficient torque to drive the wind rotor while also exhibiting good heat resistance.

[0014] Among them, the motor type can be a DC or AC motor, or even a brushless motor to improve efficiency and reduce maintenance; the power and speed of the motor must match the design of the wind wheel; and the heat dissipation design of the motor must ensure that it will not overheat during long-term operation.

[0015] In some technical solutions, optionally, the heating device includes: an electromagnetic heating device, and there is a gap between the electromagnetic heating device and the air guide cover.

[0016] In this technical solution, the heating device is an electromagnetic heating device. Specifically, an electromagnetic coil can be used as the electromagnetic heating device. The material of the air guide cover is a magnetic material, and a gap is set between the electromagnetic heating device and the air guide cover. By using an electromagnetic coil as the electromagnetic heating device, electromagnetic induction heating can be achieved. This method has the advantages of uniform heating and rapid response, which is conducive to improving heating efficiency and controlling heating temperature. In addition, the air guide cover is made of magnetic material, which helps to guide the heat field, improve thermal efficiency, reduce energy loss, and ensure that the air is heated after flowing through the air guide cover. The heated air can change the flow direction under the action of the air guide cover, and finally achieve the effect of large air volume and warm air output.

[0017] It should also be added that setting a gap between the heating device and the air guide cover can reduce the impact of the high temperature of the air guide cover on the temperature of the environment in which the heating device is located, improve the safety of use, and is also beneficial to protecting the heating device and extending its service life.

[0018] In some technical solutions, optionally, the relative magnetic permeability of the air scoop is between 1 and 10000; and / or the electrical conductivity of the air scoop is in the range of 10 5 S / m~10 8 S / m.

[0019] In this technical solution, the material of the air guide is restricted, that is, the relative magnetic permeability of the air guide is between 1 and 10000 and the electrical conductivity is within the range of 10 5 S / m to 10 8 S / m, so that the air guide cover can generate heat under the action of the magnetic field generated by the operation of the electromagnetic heating device, thereby achieving a heating effect on the air.

[0020] In some technical solutions, optionally, the electromagnetic heating device specifically includes: a heating bracket, which is arranged on the outside of the air guide cover, and an electromagnetic coil is wound around the heating bracket.

[0021] In this technical solution, the electromagnetic heating device mainly includes a heating bracket, wherein the heating bracket is arranged corresponding to the air guide cover, is arranged on the outside of the air guide cover, and is fixed to the heat dissipation housing. This helps to ensure the effective cooperation between the heating bracket and the air guide cover and provides a stable support structure. In addition, the heating bracket can be disc-shaped, that is, in the form of a coil disc. By winding an electromagnetic coil on the coil disc, an alternating magnetic field is generated when the electromagnetic coil is energized, so that the air guide cover can achieve electromagnetic induction heating, providing a highly efficient method for air heating.

[0022] In some technical solutions, optionally, it also includes: a heat insulation bracket, which is arranged on the outside of the air guide cover; wherein the air guide cover is arranged on the heat insulation bracket.

[0023] In this technical solution, a thermal insulation bracket is installed outside the air scoop. This arrangement can isolate the air scoop from the heating device to a certain extent, reducing heat conduction to the air scoop, thereby lowering the air scoop temperature and improving operational safety. Furthermore, the thermal insulation bracket is fixed to the heat dissipation housing, providing additional support and stability for the air scoop, helping to maintain its position, reduce vibration and friction, and improve the reliability of the entire system.

[0024] In general, the provision of thermal insulation brackets in this air conditioning equipment helps to improve the stability and safety of the system, while also helping to improve heating efficiency and ensure the normal operation of the entire system.

[0025] In some technical solutions, optionally, the air guide cover is arranged on the inner side of the thermal insulation bracket, and the air guide cover is connected to the thermal insulation bracket, the outer shell cover and the thermal insulation bracket are assembled to form a first assembly, and the first assembly is assembled with the heating device.

[0026] In this technical solution, an assembly method is defined, in which the heat insulation bracket is connected to the air guide cover and is located on the outside of the air guide cover. The heat insulation bracket is first assembled to the outer shell cover to form a first assembly, and then the heating device is assembled to the first assembly, thereby realizing the installation of the entire air conditioning equipment. For the first assembly, the structures included therein are not electrically charged, so it is easier for users to clean after disassembly, reducing the difficulty of cleaning.

[0027] In some technical solutions, optionally, the air guide hood is arranged on the inner side of the thermal insulation bracket, and the air guide hood is connected to the thermal insulation bracket, the thermal insulation bracket and the heating device are assembled to form a second assembly, and the second assembly is assembled with the outer shell cover.

[0028] In this technical solution, another assembly method is defined. The heat insulation bracket is connected to the air guide cover and is located on the outside of the air guide cover. The heat insulation bracket and the heating device are first assembled to form a second assembly, and then the outer shell cover is assembled to the second assembly. In this solution, the outer shell cover located on the outermost side is assembled last, which is more in line with the user's operating habits during disassembly and reduces the difficulty of disassembly and installation.

[0029] In some technical solutions, optionally, it also includes: a motor bracket, which is arranged at the air outlet end of the air guide cover, and the motor bracket is detachably connected to the air guide cover; a motor, which is arranged on the motor bracket, and the drive shaft of the motor is used to drive the wind wheel to rotate.

[0030] In this technical solution, the motor bracket is located at the air outlet of the air scoop, primarily to support and secure the motor. Furthermore, it is detachably connected to the air scoop, meaning that motor repair and replacement can be more convenient and quick. The motor bracket must be designed to ensure the motor is securely mounted while facilitating disassembly and maintenance. Of course, the motor is mounted on the motor bracket, and its drive shaft is used to drive the wind wheel. The motor is the power source for the entire air conditioning system, transferring kinetic energy to the wind wheel via the drive shaft, enabling it to rotate and generate airflow. The performance and stability of the motor significantly impact the efficiency and stability of the entire system.

[0031] The motor drives the impeller via a drive shaft, generating airflow and pushing it toward the air guide. Simultaneously, the heating bracket and heating wire heat the air, generating hot air. These components work together to enable the handpiece to quickly deliver warm air, meeting user needs. Furthermore, the detachable motor bracket design facilitates maintenance and repair.

[0032] In some technical solutions, optionally, the motor bracket includes: a fixed plate, on which the motor is arranged; a ring plate, which is arranged radially outward of the fixed plate, and the ring plate and the fixed plate are connected by ribs, and the ring plate and the air guide cover are detachably connected.

[0033] In this technical solution, the motor bracket is composed of a fixing plate, a ring plate and ribs. Specifically, the fixing plate is the main part of the motor bracket and can provide a stable mounting platform for the motor. The motor is mounted on the fixing plate, and the fixing plate needs to have sufficient strength to support the weight of the motor and the vibration generated during operation. The ring plate is arranged on the radial outside of the fixing plate, mainly serving as a connecting structure between the fixing plate and the air guide cover, that is, the entire motor bracket is connected to the air guide cover through the ring plate. The ring plate is designed to cooperate with the air guide cover, so that the entire motor bracket can be easily disassembled and connected to the air guide cover.

[0034] Ribs connect the fixed plate and the ring plate. These multiple ribs reduce wind resistance during airflow and provide additional stability and support. The ribs, fixed plate, and ring plate form a stable frame, reducing vibration during motor operation and maintaining the structural integrity of the entire bracket.

[0035] As you can understand, this design allows the motor to be securely mounted on the fixed plate. The ring plate and ribs create a removable, stable connection between the motor bracket and the air scoop. This design not only ensures the stability of the motor during operation, but also allows for ease of maintenance and replacement. When the user needs to repair or replace the motor, they can easily remove the motor bracket from the air scoop and perform the necessary operations.

[0036] In some technical solutions, optionally, the wind wheel is a centrifugal wind wheel, and the axis of the wind wheel is coaxially arranged with the axis of the outer shell cover; wherein, when the wind wheel rotates, air flows into the wind wheel from the rear side of the outer shell cover, and under the action of the wind wheel, the air is discharged toward the inner wall surface of the wind guide cover.

[0037] This technical solution uses a centrifugal impeller in air conditioning equipment, with the motor drive shaft aligned with the impeller's axis. As the impeller rotates, the centrifugal force of its blades propels air outward from the center of the impeller, where it is then channeled through an air shroud. Centrifugal impellers are suitable for applications that generate large airflows and high pressures, and are often used in equipment that requires high airflow or long-distance transport of hot air.

[0038] Furthermore, the alignment of the motor's drive shaft and the rotor axis ensures direct and efficient transmission of the motor's rotational force to the rotor, minimizing energy loss and improving system efficiency. This direct-axis connection also allows for more precise alignment of the motor and rotor, helping to reduce vibration and noise, extending the life of the equipment, while also reducing unnecessary structural design and space occupation, thereby improving space utilization.

[0039] It can be understood that the design of using a centrifugal impeller and aligning the motor drive shaft with the impeller axis can achieve efficient air flow and heating. The air is generated by the centrifugal impeller to generate high-speed airflow, which is then heated by the heating device. The resulting hot air is guided by the air guide cover and discharged from the front side of the outer cover.

[0040] In some technical solutions, optionally, the outer shell cover includes: a front mesh cover and a rear mesh cover that are detachably connected, and the front mesh cover and the rear mesh cover are connected to form a accommodating cavity for accommodating the heating device, the wind guide cover, the wind wheel and the motor; wherein, the front mesh cover is provided with a first bearing for the drive shaft to pass through.

[0041] In this technical solution, the outer housing includes detachably connected front and rear meshes, which form a chamber that houses the heating device, air deflector, impeller, and motor. The front mesh is equipped with a first bearing for the drive shaft to pass through. This detachable design facilitates maintenance and cleaning of internal components, making repairs more convenient and efficient. This is highly beneficial for routine maintenance and upkeep of the equipment.

[0042] The accommodating cavity formed by connecting the front mesh cover and the rear mesh cover provides a suitable space for arranging the heating device, the wind guide cover, the wind wheel and the motor, so that these internal components can be effectively installed and fixed.

[0043] Optionally, a first bearing for the drive shaft to pass through is provided on the front mesh cover, which helps to support and fix the drive shaft, ensures the stable operation of the drive shaft, and reduces vibration and friction caused by the movement of the drive shaft.

[0044] In general, the design of this outer shell cover improves the maintenance convenience of the equipment and the installation stability of the internal components, which is beneficial to the use and maintenance of the entire system.

[0045] In some technical solutions, optionally, the air guide cover is a rotating body, and on a plane passing through the axis of the air guide cover, the outline of the air guide cover includes multiple lines with different curvatures.

[0046] In this technical solution, since the magnetic field distribution of the electromagnetic heating device is closely related to its contour, the parallel contour of the air scoop helps to form a more uniform magnetic field on the scoop surface, thereby improving heating efficiency and uniformity. Furthermore, the structure of the rotating body ensures that the heat received by the air scoop is evenly distributed, reducing thermal stress and material fatigue caused by uneven heating. It also facilitates smooth airflow, reduces wind resistance, improves airflow efficiency, and allows the heated air to be delivered more efficiently.

[0047] An embodiment of the second aspect of the present invention provides a heater, comprising: any one of the air conditioning devices in the first aspect; and a base bracket detachably connected to the air conditioning device.

[0048] The heater according to the present invention includes a detachably connected air conditioning unit and a base bracket. The base bracket is detachably connected to the air conditioning unit, facilitating assembly and disassembly of the unit, making it more flexible and easier to transport and maintain. The base bracket provides firm support, helping to maintain the stability of the heater, reducing shaking and wobbling during operation, and improving its safety and reliability.

[0049] In addition, since the base bracket is detachably connected to the air conditioning device, different air conditioning devices can be selected as needed, making the heater more widely applicable and flexible.

[0050] An embodiment of the third aspect of the present invention provides a control method for any of the above-mentioned air conditioning equipment, the control method comprising: in response to a warm air start-up instruction, controlling the rotation of the wind wheel, so that at least part of the air flows from the rear side of the outer shell cover into the air inlet side of the wind wheel; according to the warm air start-up instruction, controlling the operation of the heating device, and under the action of the wind wheel, the air is radially discharged to the inner wall surface of the air guide cover, the air is heated by the air guide cover and guided to the air outlet side of the outer shell cover, and discharged outward.

[0051] The control method of this solution effectively generates a large volume of hot air, effectively heating the space. Specifically, the entire process begins by controlling the rotor's rotation in response to a warm air start command. This command is typically issued by the user through a controller (such as a remote control or smart home system), and the rotor's rotation is driven by a motor. The rotor's function is to draw in air and propel it forward. Due to the device's design, some or all of the air is drawn from the outside into the rotor's inlet side. Simultaneously, the rotor's rotation creates a negative pressure on the inlet side of the air duct—a pressure lower than the ambient pressure—which helps draw in more air. This negative pressure allows for more effective control of the air flow direction and volume. Furthermore, upon a start command, the heating device begins operating. This is typically achieved using an electric heating element (such as a heating wire) or electromagnetic heating principles. Under the action of the rotor, air is pushed radially (from the center outward) and heated as it passes through the air scoop. The air scoop not only heats the air but also directs it in a designated direction. Finally, the heated air is discharged through the outlet side of the outer hood, distributing the heat throughout the room. This process not only increases the temperature of the room but also helps circulate the air.

[0052] The effect of the entire process is to convert cold air into hot air and distribute the hot air evenly into the environment, thereby achieving the purpose of heating and improving comfort.

[0053] Additional aspects and advantages of the invention will become apparent from the description which follows, or may be learned by practice of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0077] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0078] Refer to the following Figures 1 to 19 Some embodiments according to the present invention are described.

[0079] This embodiment proposes an air conditioning device 100, such as Figure 1As shown, it mainly includes an outer shell 102 and a heating device 104, an air scoop 106, and an air flow adjustment component 107 arranged inside the outer shell 102. Specifically, the outer shell 102 provides a sturdy protective shell for the air conditioning device 100. It not only protects the internal structure from damage, but also can be made of materials that have heat insulation and insulation functions to ensure the safety of users during use. The heating device 104 is the core of the air conditioning device 100 and is responsible for converting electrical energy into thermal energy. The heating device 104 is arranged corresponding to the air scoop 106 and can increase the temperature of the air scoop 106. Specifically, the heating device 104 can be composed of a high-temperature resistant resistance wire, or it can also use more efficient materials such as PTC ceramics, or even an electromagnetic coil. Part or all of the structure of the air flow adjustment component 107 is located inside the air scoop 106. When the air flow adjustment component 107 is in operation, it can generate a strong airflow. This airflow is heated when passing through the heated air scoop 106 and is eventually discharged from the front side of the air conditioning device 100.

[0080] It can be understood that the air conditioning device 100 can mainly convert electrical energy into thermal energy and mechanical energy to generate hot air.

[0081] The airflow adjustment assembly 107 includes a wind wheel 108 and a motor 110. By adjusting the relative positions of the motor 110 and the wind wheel 108 and adding the structure of the wind guide 106, the air will be blown toward the wind guide 106 under the action of the wind wheel 108. The wind guide 106 is heated under the action of the heating device 104, which can increase the temperature of the air blown into the wind guide 106. At the same time, the structural characteristics of the wind guide 106 itself can guide the air to the outside of the air conditioning device 100, thereby providing warm air with a higher wind speed. The wind guide 106 achieves the dual functions of heating and guiding, which can reduce the wind resistance caused by the heating process of the prior art. Among them, the wind guide 106 can be a one-piece structure or a structure composed of multiple parts. The heating area of ​​the wind guide 106 can be the area where the airflow generated by the wind wheel 108 of the airflow adjustment assembly 107 initially contacts the wind guide 106, or it can be the area after the initial contact, or both.

[0082] It should be noted that by providing a motor 110 and extending its drive shaft 1102 into and engaging with the wind rotor 108, the drive shaft 1102 can be controlled to rotate the wind rotor 108 when the motor 110 is running. It will be appreciated that the motor 110 provides the necessary power, converting electrical energy into mechanical energy, enabling the wind rotor 108 to rotate and generate airflow. The design of the motor 110 must ensure sufficient torque to drive the wind rotor 108 while also exhibiting good heat resistance.

[0083] Among them, the motor type can be a DC or AC motor, or even a brushless motor to improve efficiency and reduce maintenance; the power and speed of the motor 110 must match the design of the wind wheel 108; the heat dissipation design of the motor 110 must ensure that it will not overheat during long-term operation.

[0084] In one embodiment, optionally, the heating device 104 is an electromagnetic heating device 1052, and specifically, an electromagnetic coil can be used as the electromagnetic heating device 1052, the material of the air guide cover 106 is a magnetic material, and a gap is set between the electromagnetic heating device 1052 and the air guide cover 106. By adopting an electromagnetic coil as the electromagnetic heating device 1052, electromagnetic induction heating can be achieved. This method has the advantages of uniform heating and rapid response, which is conducive to improving heating efficiency and controlling heating temperature. In addition, the air guide cover 106 is made of a magnetic material, which helps to guide the heat field, improve thermal efficiency, reduce energy loss, and ensure that the air is heated after flowing through the air guide cover 106. The heated air can change the flow direction under the action of the air guide cover 106, and finally achieve the effect of large air volume and warm air.

[0085] It should also be added that a gap is set between the heating device 104 and the air guide cover 106 to reduce the impact of the high temperature of the air guide cover 106 on the temperature of the environment in which the heating device 104 is located, thereby improving the safety of use, and is also beneficial to protecting the heating device 104 and extending its service life.

[0086] In some embodiments, the material of the air scoop 106 is optionally limited, that is, the relative magnetic permeability of the air scoop 106 is between 1 and 10000 and the electrical conductivity range is 10 5 S / m to 10 8 S / m, so that the air guide cover 106 can generate heat under the action of the magnetic field generated by the operation of the electromagnetic heating device 1052, thereby achieving a heating effect on the air.

[0087] Optionally, the relative magnetic permeability of the air scoop 106 is further limited to between 1 and 2000.

[0088] In some embodiments, the electromagnetic heating device 1052 optionally includes a heating bracket 1042, wherein the heating bracket 1042 is provided corresponding to the air scoop 106, and is provided on the outside of the air scoop 106 and fixed to the heat dissipation housing 114. This helps ensure the effective cooperation between the heating bracket 1042 and the air scoop 106 and provides a stable support structure. In addition, the heating bracket 1042 can be disc-shaped, that is, in the form of a coil disc 1044. By winding an electromagnetic coil on the coil disc 1044, an alternating magnetic field is generated when the electromagnetic coil is energized, so that the air scoop 106 is heated by electromagnetic induction, providing a highly efficient method for heating the air.

[0089] In some embodiments, a heat-insulating bracket 1062 is optionally included. Heat-insulating bracket 1062 is disposed outside of air scoop 106. The provision of heat-insulating bracket 1062 can, to a certain extent, isolate air scoop 106 from heating device 104, reducing heat conduction to air scoop 106, thereby lowering the temperature of air scoop 106 and improving safety. Furthermore, heat-insulating bracket 1062 is secured to heat dissipation housing 114, providing additional support and stability for air scoop 106, helping to maintain the stable position of air scoop 106, reducing vibration and friction, and improving the reliability of the entire system.

[0090] The heat-insulating bracket 1062 can not only isolate and stabilize the air guide cover 106 , but also help improve the working efficiency of the heating device 104 , ensuring that the heated air can smoothly enter the heat dissipation housing 114 and then be pushed out by the wind wheel 108 .

[0091] It should be added that, in one embodiment, the heat insulation bracket 1062 serves as a part of the air guide cover 106 .

[0092] In general, the provision of the thermal insulation bracket 1062 in the air conditioning device 100 helps to improve the stability and safety of the system, while also being beneficial to improving the thermal insulation purpose and ensuring the normal operation of the entire system.

[0093] In some embodiments, optionally, an assembly method is defined, in which the heat insulation bracket 1062 is connected to the air guide cover 106 and is located on the outside of the air guide cover 106. The heat insulation bracket 1062 is first assembled to the outer shell cover 102 to form a first assembly, and then the heating device 104 is assembled to the first assembly, thereby realizing the installation of the entire air conditioning equipment 100. For the first assembly, the structures included therein are not electrically charged, so it is easier for users to clean after disassembly, reducing the difficulty of cleaning.

[0094] In some embodiments, optionally, another assembly method is defined, in which the heat insulating bracket 1062 is connected to the air guide cover 106 and is located on the outside of the air guide cover 106. The heat insulating bracket 1062 and the heating device 104 are first assembled to form a second assembly, and then the outer shell cover 102 is assembled to the second assembly. In this solution, the outer shell cover 102 located on the outermost side is assembled last, which is more in line with the user's operating habits during disassembly and reduces the difficulty of disassembly and installation.

[0095] In some embodiments, optionally, as Figure 10As shown, the motor bracket 118 is arranged at the air outlet end of the air duct 106, mainly used to support and fix the motor 110. In addition, it is detachably connected to the air duct 106, which means that the maintenance and replacement of the motor 110 can be more convenient and quick. The design of the motor bracket 118 needs to ensure the stable installation of the motor 110, while being easy to disassemble and maintain. Of course, the motor 110 is mounted on the motor bracket 118, and its drive shaft 1102 is used to drive the wind wheel 108 to rotate. The motor 110 is the power source of the entire air conditioning equipment 100. It transfers kinetic energy to the wind wheel 108 through the drive shaft 1102, so that the wind wheel 108 can rotate and generate airflow. The performance and stability of the motor 110 have an important impact on the working efficiency and stability of the entire equipment.

[0096] Motor 110 drives impeller 108 via drive shaft 1102, generating airflow and pushing it toward air guide hood 106. Simultaneously, the air guide hood heats the air it contacts, generating hot air. The synergistic effect of these structures enables the handpiece to quickly deliver warm air, meeting user needs. Furthermore, the detachable design of motor bracket 118 facilitates maintenance and repair of the device.

[0097] In some embodiments, optionally, as Figure 7 As shown, the motor bracket 118 is composed of a fixing plate 1182, a ring plate and ribs. Specifically, the fixing plate 1182 is the main part of the motor bracket 118, which can provide a stable installation platform for the motor 110. The motor 110 is mounted on the fixing plate 1182, and the fixing plate 1182 needs to have sufficient strength to support the weight of the motor 110 and the vibration generated during operation. The ring plate is arranged on the radial outside of the fixing plate 1182, mainly serving as a connecting structure between the fixing plate 1182 and the air guide cover 106, that is, the entire motor bracket 118 is connected to the air guide cover 106 through the ring plate. The ring plate is designed to cooperate with the air guide cover 106, so that the entire motor bracket 118 can be easily disassembled and connected to the air guide cover 106.

[0098] Furthermore, ribs are provided to connect the fixing plate 1182 and the ring plate. These ribs reduce wind resistance during airflow and provide additional stability and support. The ribs form a relatively stable frame structure between the fixing plate 1182 and the ring plate, reducing vibration during operation of the motor 110 and maintaining the structural integrity of the entire bracket.

[0099] It can be understood that through this design, the motor 110 can be securely mounted on the fixing plate 1182. At the same time, the ring plate and rib structure form a removable and stable connection between the motor bracket 118 and the air scoop 106. This design not only ensures the stability of the motor 110 during operation, but also takes into account the convenience of maintenance and replacement. When the user needs to repair or replace the motor 110, the motor bracket 118 can be easily removed from the air scoop 106 to perform the corresponding operation.

[0100] In some embodiments, a centrifugal impeller 108 is optionally used in the air conditioning device 100, and the drive shaft 1102 of the motor 110 coincides with the axis of the impeller 108. When the centrifugal impeller 108 rotates, the centrifugal force of its blades propels air outward from the center of the impeller 108, and then guides the hot air out through the air guide 106. The centrifugal impeller 108 is suitable for applications that generate a large amount of air flow and a high air pressure, and is often used in equipment that requires a large air volume or that requires the transport of hot air over long distances.

[0101] Furthermore, the alignment of the drive shaft 1102 of the motor 110 with the axis of the rotor 108 ensures that the rotational force of the motor 110 is directly and efficiently transmitted to the rotor 108, reducing energy loss and improving system efficiency. This direct-axis connection also allows for more precise alignment of the motor 110 and rotor 108, helping to reduce vibration and noise, extending the life of the equipment, while also reducing unnecessary structural design and space occupation, thereby improving space utilization.

[0102] It is understood that the use of centrifugal impeller 108 and the alignment of motor 110 drive shaft 1102 with the impeller 108 axis can achieve efficient air flow and heating. The air is driven by centrifugal impeller 108 to generate a high-speed airflow, which is then heated by heating device 104. The resulting hot air is then guided by air guide hood 106 and discharged from the front side of outer housing 102.

[0103] In some embodiments, the outer shell 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 wind guide cover 106, the wind wheel 108 and the motor 110, wherein Figure 8 As shown, the front mesh cover 1022 is provided with a first bearing 1122 for the drive shaft 1102 to pass through. The detachable connection between the front mesh cover 1022 and the rear mesh cover 1024 facilitates 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.

[0104] The accommodating cavity formed by the connection of the front mesh cover 1022 and the rear mesh cover 1024 provides a suitable space for accommodating the heating device 104, the wind guide cover 106, the wind wheel 108 and the motor 110, so that these internal components can be effectively installed and fixed.

[0105] Optionally, a first bearing 1122 for the drive shaft 1102 to pass through is provided on the front mesh cover 1022 , which helps to support and fix the drive shaft 1102 , ensures the stable operation of the drive shaft 1102 , and reduces vibration and friction caused by the movement of the drive shaft 1102 .

[0106] In general, the design of the outer shell 102 improves the maintenance convenience of the equipment and the installation stability of the internal components, which is beneficial to the use and maintenance of the entire system.

[0107] In some embodiments, optionally, since the magnetic field distribution of the electromagnetic heating device 1052 is closely related to its contour shape, by limiting the air guide cover 106 to a rotating body structure, and on the axial section of the air guide cover 106, that is, on the plane passing through the axis, the contour is composed of multiple curves with different curvatures, thereby facilitating the smooth passage of airflow, reducing wind resistance, and improving airflow efficiency, so that the heated air can be delivered more efficiently.

[0108] Limiting the contour of the air guide cover 106 to be parallel thereto helps to form a more uniform magnetic field on the surface of the air guide cover 106, thereby improving heating efficiency and uniformity.

[0109] Heat dissipation structure of electromagnetic heating

[0110] In this embodiment, Figure 2 and Figure 10 As shown, a heat dissipation shell 114 may be provided, and a heat dissipation channel for heat dissipation is formed between the heat dissipation shell 114 and the wind guide cover 106. The electromagnetic heating device 1052 may be arranged in the heat dissipation channel. The heat dissipation shell 114 may serve as the outermost shell of the entire air-conditioning equipment. For example, the heat dissipation shell 114 is the above-mentioned outer shell 102. Of course, the heat dissipation shell 114 may also be an independent intermediate shell.

[0111] By providing a heat dissipation channel for accommodating the electromagnetic heating device 1052 in the outer shell 102, air can flow in and out due to the structural characteristics of the heat dissipation shell 114 itself. The electromagnetic heating device will generate a large amount of heat when in operation. By providing the heat dissipation shell 114, a heat dissipation channel will be formed between it and the air guide cover 106. When the air flows, it can take away the heat of the electromagnetic heating device 1052, thereby effectively solving the temperature rise problem of the electromagnetic heating device.

[0112] The heat dissipation housing 114 is composed of three parts, such as Figure 3As shown, it specifically comprises an air inlet section 1142, a heat dissipation section 1144 and a negative pressure section 1146. By arranging an electromagnetic heating device 1052 in the heat dissipation section 1144, when the electromagnetic heating device 1052 is running, since the negative pressure section 1146 is connected to the air inlet end of the wind wheel 108, air negative pressure will be generated in the negative pressure section 1146, driving the air flow in the heat dissipation shell 114. Specifically, the outside cold air flows in from the air inlet section 1142, flows through the upper and lower surfaces of the electromagnetic heating device 1052, takes away the heat around the electromagnetic heating device 1052, and finally flows into the wind wheel 108 through the air inlet end of the wind wheel 108, thereby realizing the heat dissipation of the electromagnetic heating device 1052. Among them, the air guide cover 106 and / or the heat insulation bracket 1062 are provided with an internal air inlet section, an internal heat dissipation section and an internal negative pressure section corresponding to the air inlet section 1142, the heat dissipation section 1144 and the negative pressure section 1146. A heat dissipation channel is formed between the air inlet section 1142, the heat dissipation section 1144 and the negative pressure section 1146 and the internal air inlet section, the internal heat dissipation section and the internal negative pressure section. The heat dissipation channel is correspondingly provided with an air inlet channel section, a heat dissipation channel section and a negative pressure channel section, wherein the negative pressure channel section is located on the air inlet side of the wind wheel 108 and is connected to the inside of the wind wheel 108. The negative pressure channel section is in a negative pressure state when the wind wheel 108 is working. Under the action of this negative pressure, the external air enters the heat dissipation channel section from the air inlet channel section, and finally enters the wind wheel 108 from the negative pressure channel section.

[0113] By defining the relative positions of the negative pressure section 1146 and the heat dissipation section 1144, that is, overlapping in the axial direction of the impeller 108, and maintaining their connection, the air flow in the negative pressure section 1146 and the air flow in the heat dissipation section 1144 are axially opposite, generating negative pressure under the action of the negative pressure section 1146, thereby guiding air into the impeller 108, thereby achieving the dual functions of heat dissipation and air outlet for the single impeller 108. Specifically, the negative pressure section 1146 extends obliquely toward the center at one end away from the heat dissipation section 1144, and the corresponding negative pressure channel section extends obliquely toward the center at the other end of the heat dissipation channel section.

[0114] Alternatively, as Figure 2As shown, the specific structure of the heat dissipation shell 114 is defined, including a first air inlet portion 1152 that provides a channel for axial air inlet to the wind wheel. The first air inlet portion 1152 is in the shape of a hole or a grille or a grid, which ensures normal axial air inlet to the wind wheel when it rotates. At the same time, since the heat dissipation shell 114 has a channel portion 1154 that forms a partial heat dissipation channel, the channel portion 1154 includes an air inlet section 1142, a heat dissipation section 1144 and a negative pressure section 1146. The heat dissipation channel includes a second air inlet portion 1156 corresponding to the negative pressure section 1146, that is, the above-mentioned negative pressure channel section. When air enters axially, negative pressure will be generated on the second air inlet portion 1156. Under the action of the negative pressure, the air in the heat dissipation channel will flow accordingly. When no fan is provided in the heat dissipation channel, air flow in the heat dissipation channel can be achieved, the number of components can be reduced, and the weight of the overall equipment can be reduced.

[0115] It can be understood that part of the air flows into the wind wheel through the first air inlet 1152, and another part of the air can flow into the wind wheel through the second air inlet 1156.

[0116] In some embodiments, a heat dissipation channel may optionally connect the front side of the outer cover 102 and the axial rear side of the impeller 108 to guide air flow. When the impeller 108 rotates, air flows from the front side of the outer cover 102 into the heat dissipation housing 114, and then passes through the axial rear side of the impeller 108 and enters the impeller 108.

[0117] It should be added that when the wind wheel 108 rotates, the above-mentioned relative position setting can generate negative pressure to inhale cold air, and cold air can be blown into the heat dissipation shell 114 without the need to set up an additional fan. At the same time, after the cold air is introduced, it first dissipates heat to the electromagnetic heating device 1052, the air flow temperature rises, and then it is introduced into the wind wheel 108 and the wind guide cover 106, and is heated again by the heating side wall of the wind guide cover 106, so that the heat is effectively utilized.

[0118] It can be understood that the heat dissipation housing 114 ensures that the air passing through the electromagnetic heating device 1052 is effectively guided to the wind wheel 108 and pushed out by the wind wheel 108. Overall, the design of forming a heat dissipation channel between the heat dissipation housing 114 and the air guide cover 106 is conducive to improving the efficiency and stability of air flow, thereby increasing the performance and reliability of the entire system.

[0119] In some embodiments, optionally, by limiting part of the wind wheel 108 or all of the wind wheel 108 to be set inside the wind guide cover 106, the air driven by the wind wheel 108 when rotating will fully flow into the wind guide cover 106, and after heat exchange with the wind guide cover 106, it will be blown out under the guidance of the wind guide cover 106, thereby achieving the blowing of hot air.

[0120] By selecting an electromagnetic coil as the electromagnetic heating device 1052, the material of the air guide cover 106 is a magnetic conductive material. Electromagnetic heating is performed by generating eddy currents within a few tenths of a millimeter on the surface of the air guide cover 106 under the action of the electromagnetic heating device 1052, thereby forming a heating effect. When the thickness of the air guide cover 106 is relatively small, eddy currents will be generated inside the entire air guide cover 106, thereby achieving heating.

[0121] It can be understood that without affecting the heating effect, the distance between the electromagnetic heating device 1052 and the wind guide cover 106 is as far as possible. A long distance can reduce the heat conducted from the wind guide cover 106 to the electromagnetic heating device 1052 and prevent the electromagnetic heating device 1052 from overheating.

[0122] In some embodiments, optionally, as Figure 3 As shown, an independent heat dissipation fan 116 is provided in the heat dissipation housing 114 to enhance the air flow in the heat dissipation housing 114 , wherein the heat dissipation fan 116 can drive cold air to flow into the heat dissipation housing 114 , or suck out the hot air after heat dissipation, thereby realizing the air flow in the heat dissipation housing 114 .

[0123] Optionally, the heat dissipation fan may be arranged at any position inside or outside the heat dissipation channel, as long as it can drive the air flow in the heat dissipation channel.

[0124] In some embodiments, the electromagnetic heating device 1052 may optionally utilize a planar coil. In this case, the heat dissipation housing 114 forms independent channels above and below the planar coil during flow, thereby allowing the air within the heat dissipation housing 114 to pass through both sides of the current heating device, thereby achieving a heat dissipation effect. Alternatively, the electromagnetic heating device 1052 may utilize a toroidal coil. In this case, the heat dissipation housing 114 forms independent channels radially inside and outside the planar coil during flow, thereby allowing the air within the heat dissipation housing 114 to pass through both sides of the current heating device, thereby achieving a heat dissipation effect.

[0125] In some embodiments, the air flow direction within the heat dissipation housing 114 is optionally limited so that the cool air flows parallel to the electromagnetic heating device 1052, specifically parallel to the coil within the electromagnetic heating device 1052. This allows the air to flow over the upper and lower surfaces of the coil, removing heat. After the air temperature rises, it is discharged from the other end. Because the airflow is parallel to the electromagnetic heating device 1052, the heat dissipation resistance is relatively low, thereby efficiently dissipating heat.

[0126] Electromagnetic Coil Structure

[0127] like Figure 11As shown, the limiting air guide cover 106 has an air inlet side and an air outlet side located on both sides of the axial direction, wherein the air inlet side is the rear side, the air outlet side is the front side, and the axial side is the air inlet side. The air flows in from the air inlet side and then flows out from the air outlet side. In the axial direction, the diameter of the air guide cover on the air inlet side is smaller, that is, the first diameter d1 on the air inlet side is smaller than the second diameter d2 on the air outlet side. The air guide cover is in an expanded shape as a whole to facilitate the air to flow on the inner wall of the air guide cover and diffuse and discharge.

[0128] Among them, such as Figure 11 As shown, the wind wheel 108 is located in the wind guide cover 106, and its rotation will generate a strong airflow. The airflow is heated when passing through the heated wind guide cover 106 and is finally discharged from the front side of the nose.

[0129] In some embodiments, optionally, a gap d is set between the heating device 104 and the air guide cover 106, which helps to lower the temperature of the air guide cover 106, reduce the conduction of heat to the air guide cover 106, improve the safety of use, and is also beneficial to protecting the heating device 104 and extending its service life.

[0130] In some embodiments, optionally, as Figure 11 As shown, limiting the gap d to greater than 5 mm can help dissipate heat from the electromagnetic heating device 1052, preventing damage to internal components or shortening the life of the heating device 104 due to overheating. The gap allows air circulation, which helps disperse the heat generated by the electromagnetic heating device 1052. It will be appreciated that in electromagnetic heating, the size of the gap affects the distribution of the electromagnetic field, thereby affecting heating efficiency and uniformity. A gap that is too small may result in excessive local heating, while a gap that is too large may reduce heating efficiency.

[0131] It can be understood that by limiting the gap d to be greater than 5 mm, the heat dissipation of the electromagnetic heating device 1052 can be effectively ensured.

[0132] In some embodiments, optionally, limiting the gap d to less than 30 mm helps maintain the magnetic field strength generated by electromagnetic induction, thereby ensuring that the air scoop 106 can be effectively heated. If the gap is too large, the magnetic field strength will decrease, resulting in reduced heating efficiency. It will be understood that a smaller gap can enhance the coupling efficiency between the electromagnetic heating device 1052 and the air scoop 106, making energy transfer more efficient. This helps improve the overall heating performance of the heater.

[0133] Maintaining the gap within a certain range helps to more accurately control the temperature of the air guide cover 106 because the distribution and intensity of the magnetic field have a direct impact on the heating temperature.

[0134] It can be understood that by limiting the gap d to less than 30 mm, the coupling between the electromagnetic heating device 1052 and the air guide cover 106 can be effectively ensured.

[0135] In some embodiments, the front and rear calibers of the electromagnetic heating device 1052 are optionally restricted. Specifically, the electromagnetic heating device 1052 has two ends corresponding to the air inlet side and the air outlet side of the air guide cover 106, wherein the opening size of the end corresponding to the air inlet side is the third caliber, and the opening size of the end corresponding to the air outlet side is the fourth caliber. By limiting the fourth caliber of the electromagnetic heating device 1052 to be larger, the overall caliber change trend of the electromagnetic heating device 1052 is smaller than that of the air guide cover 106, that is, the gap between the electromagnetic heating device 1052 and the air guide cover 106 changes less, ensuring the heating effect of the electromagnetic heating device 1052 on the air guide cover 106 at different positions. The electromagnetic heating device 1052 and the air guide cover 106 are both larger in front and smaller in the back, which is more convenient to meet the use requirements of large air volume and warm air output.

[0136] In some embodiments, the waistline shape of the air scoop 106 is optionally defined, that is, on a cross section passing through the axis of the air scoop 106, the outline of part or all of the air scoop 106 is a parabola, which can reduce the wind resistance of air flowing along the inner wall of the air scoop 106. Alternatively, the waistline shape of the electromagnetic heating device 1052 is optionally defined, that is, on a cross section passing through the axis of the electromagnetic heating device 1052, the outline of part or all of the electromagnetic heating device 1052 is a parabola, so that the electromagnetic heating device 1052 heats the air scoop 106 more uniformly. Alternatively, the waistline shapes of both the air scoop 106 and the electromagnetic heating device 1052 are simultaneously defined, and at least part of the outline of both is defined as a parabola.

[0137] Heater Control Method

[0138] This embodiment provides a method for controlling a heater. Figure 12 Shown, including:

[0139] Step S102: determining the gear parameters of the heater in the warm air mode, where the gear parameters include associated heating power and / or fan power;

[0140] Step S104: Control the operation of the heating device according to the heating power corresponding to the gear parameter, and / or control the operation of the wind wheel according to the fan power corresponding to the gear parameter, so that the air generated by the rotation of the wind wheel is discharged toward the inner wall surface of the air guide cover, and the air is heated by the air guide cover and discharged outward from the front side of the outer cover.

[0141] As for the control method, when the heater is in warm air mode, the gear parameters are determined to set the operating mode of the heater, including heating power and fan power. This step directly controls the heater to operate with the heating power and fan power corresponding to the gear when it is started. The two powers are pre-associated and set to achieve rough gear adjustment. Users can choose the appropriate temperature and wind speed according to their needs to achieve a personalized comfort experience. The operation of the heating device is then controlled according to the set heating power, which can convert electrical energy into thermal energy to heat the air, thereby increasing the temperature of the air in the air guide cover and providing a heat source for heating. The speed of the wind wheel is controlled according to the set fan power, which can generate sufficient wind force to drive the heated air to flow, so that the heated air is evenly distributed and discharged through the front side of the outer cover, thereby quickly and effectively delivering warm air.

[0142] The integrated heater control method enables precise control of the heater to meet various requirements. By setting gear parameters, the heating and fan power are adjusted to achieve the user's desired temperature and wind speed. This provides a flexible, efficient, and safe heater adjustment system that not only meets the user's personalized temperature and wind speed needs, but also ensures the heater's energy efficiency and safety.

[0143] Overall, this control method enables the heater to work more intelligently, improving the user experience while optimizing energy usage and avoiding overheating or unnecessary energy waste, thus achieving the goals of energy saving and safety.

[0144] It can be understood that a usage scenario applied according to the embodiment provided in this application is as follows: the metal air guide cover 106 is inductively heated by the electromagnetic heating device 1052 to generate heat, and under the action of the wind wheel, the air flow is thrown out and hits the heated air guide cover 106, and is blown out from the grille after heat exchange and rectification.

[0145] The heater can be used for both cooling and heating, that is, there is a cooling mode and a heating mode. In cooling mode, you only need to start the fan module separately. In heating mode, there are at least three gear settings, each of which has a set of preset heating power and fan power. When it starts, it runs at the preset power. On this basis, the user can adjust the heating power and fan power according to their personal experience needs. Therefore, the heater can achieve different wind speeds at the same heating power, and can also achieve different heating powers at the same fan speed.

[0146] During operation, the heater will adjust the heating or fan power (such as reducing the heating power or stopping heating) according to the monitored temperature (such as power devices, cable reel temperature rise, outlet position temperature, etc.) to prevent safety problems caused by excessive temperature rise.

[0147] In some embodiments, optionally, it also includes: receiving a first power adjustment instruction for the heating device and / or a second power adjustment instruction for the wind wheel; determining the adjusted heating power according to the first power adjustment instruction, and controlling the operation of the heating device according to the adjusted heating power; determining the adjusted fan power according to the second power adjustment instruction, and controlling the operation of the wind wheel according to the adjusted fan power.

[0148] By receiving at least one of the first power adjustment instruction and the second power adjustment instruction, the heater can receive instructions from the user or the automatic control system to adjust the heating power and the fan power, thereby ensuring that the heater can flexibly adjust the operating status according to actual needs, improving the user's operating convenience and the response speed of the equipment.

[0149] Optionally, the adjusted heating power is determined and the operation of the heating device is controlled. According to the first power adjustment instruction received, the new heating power to be set is calculated and determined, and the heating device is operated according to this power. The output of the heating device can be accurately controlled, thereby effectively controlling the heating temperature, ensuring the warmth required by the user, and avoiding overheating.

[0150] Optionally, the adjusted fan power is determined and the operation of the wind wheel is controlled. According to the second power adjustment instruction received, the new fan power that needs to be set is calculated and determined, and the wind wheel is operated according to this power. By adjusting the speed of the wind wheel, the wind force can be controlled, thereby adjusting the airflow and distribution in the room to ensure uniform delivery of warm air and comfort.

[0151] The overall control method allows the heater to independently adjust the heating power and fan power, responding to the user's personalized settings or the intelligent adjustment of the automation system, so that users can enjoy a more precise and personalized temperature control experience. At the same time, the energy efficiency of the heater is optimized, avoiding unnecessary energy waste and improving the economy and safety of the equipment.

[0152] In summary, this control method enhances the adaptability and intelligence of the heater, improves the user experience, and helps achieve the goal of energy conservation and emission reduction.

[0153] In some embodiments, optionally, it further includes: determining the temperature inside the heater; and when the temperature is greater than a temperature threshold, reducing the heating power and / or increasing the fan power.

[0154] An intelligent temperature control mechanism ensures the heater maintains a balance between efficiency and safety. By real-time monitoring and automatic adjustment of heating and blower power, this not only improves user safety but also adjusts energy usage based on actual needs, improving energy efficiency and extending device life. Specifically, the temperature inside the heater is determined by monitoring the actual temperature inside the heater. Real-time temperature monitoring prevents overheating and ensures the heater operates within a safe temperature range, avoiding potential equipment damage or fire risks.

[0155] When the monitored temperature exceeds the set safety threshold, the system automatically adjusts to reduce heating power or increase fan power. Reducing heating power reduces heat generation, while increasing fan power increases heat dissipation. Both help to quickly reduce the internal temperature of the heater, maintaining normal operation of the equipment and user comfort.

[0156] In some embodiments, optionally, it further includes: determining the operating mode of the heater; when the heater operates in the cold air mode, controlling the wind wheel to operate and controlling the heating device to stop operating.

[0157] First, determine the operating mode of the heater, and then set whether the heater is running in cold air mode or warm air mode according to the user's choice or preset program, to ensure that the heater can provide appropriate air output according to the user's needs, increasing the flexibility of the equipment and the user's satisfaction. On this basis, control the fan wheel and heating device in the cold air mode. When the heater is in cold air mode, start the fan wheel to generate cold air, while ensuring that the heating device is not running, providing pure cold air, which is suitable for cooling the environment when the temperature is high, while avoiding unnecessary energy consumption. It can be understood that if the cold air mode is selected when the heater is started, there will be no stop action. If the heater switches from warm air mode to cold air mode, there will be a control stop action.

[0158] In some embodiments, optionally, it also includes: receiving a stop instruction; according to the stop instruction, when the heater is running in cold air mode, controlling the wind wheel to stop running, or when the heater is running in warm air mode, controlling the heating device to stop running and controlling the wind wheel to stop running.

[0159] In this embodiment, when the heater needs to be shut down, the system can receive a stop command from the user or the automatic control system, ensuring that the user can shut down the device at any time, conveniently controlling usage time, improving safety, and reducing energy waste. Based on the received stop command, the fan rotor is stopped in cold air mode, and the heating device and fan rotor are stopped in warm air mode. This allows for rapid response to the stop command and immediate termination of device operation, ensuring safety and saving energy.

[0160] In some embodiments, optionally, it also includes: determining the operating mode corresponding to the received air outlet instruction; when the operating mode is a warm air mode, controlling the wind wheel to rotate, and controlling the electromagnetic heating device to operate to heat the air guide cover; when the operating mode is a cold air mode, controlling the wind wheel to rotate, and controlling the electromagnetic heating device not to operate.

[0161] Resistance Heating

[0162] In this embodiment, the air handling device includes an outer shell 102, an air guide 106, and a wind wheel 108. The wind guide 106 is disposed inside the outer shell 102. The wind wheel 108 is disposed inside the wind guide 106. The wind wheel 108 rotates to discharge air toward the inner wall of the wind guide 106 and is discharged outward from the outer shell 102. Figure 8 As shown, unlike the electromagnetic heating device 1052 , the heating device 104 in this embodiment uses a resistance heating device 1054 . The resistance heating device 1054 is disposed in the outer shell 102 , and is used to heat the air blown from the wind wheel 108 to the wind guide cover 106 .

[0163] When heating is required, the airflow driven by the rotation of the impeller 108 flows toward the inner wall of the air guide hood 106, where it is heated by the resistance heating device 1054 and ultimately discharged outward through the front side of the outer shell 102. It should be emphasized that the heating of the air by the resistance heating device 1054 includes, but is not limited to, direct heating and indirect heating. It is understood that direct heating involves 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 then exchanging heat with the heated structure to achieve a higher temperature.

[0164] The resistance heating device 1054 is primarily used to heat the air blown out by the impeller 108. When powered, the resistance heating device 1054 generates heat, which is transferred to the moving air, raising the air temperature. The material, resistance characteristics, and layout design of the resistance heating device 1054 all affect the heating efficiency and uniformity.

[0165] The resistance heating device 1054 can be integrally injection molded and disposed on the inner wall and / or outer wall of the air scoop 106 and / or embedded within the air scoop 106. Alternatively, the resistance heating device 1054 can be disposed on the inner wall and / or outer wall of the air scoop 106 by winding, or the resistance heating device 1054 can be disposed in the space between the air scoop 106 and the impeller 108 via a bracket. The resistance heating device 1054 can be a heating wire or a heating tube. Some specific embodiments are described in detail below.

[0166] In some embodiments, optionally, as Figure 2 and Figure 3As shown, the resistance heating device 1054 is a heating wire. A heating bracket 1042 is also provided on the air guide 106 to secure the heating wire and maintain it in place. This ensures uniform heating of the heating wire and prevents uneven heat distribution or equipment damage caused by wire displacement. The design of the heating bracket 1042 generally takes into account heat resistance and structural stability, so that it can withstand high temperatures without deformation.

[0167] It should be added that heat exchange occurs between the air and the heating wire.

[0168] The heating wires are mounted on the heating bracket 1042 and primarily convert electrical energy into heat, heating the air blown out by the impeller 108 and passing through the heating wires. The heating wires' material (e.g., nickel-chromium alloy) and electrical resistance properties influence their heating efficiency and lifespan. The heating wires' layout and power design also determine the uniformity and speed of heating.

[0169] As the impeller 108 rotates, it draws in cool air and pushes it toward the air guide hood 106. As the air passes through the resistance heating device 1054 on the heating bracket 1042, it is heated and transformed into hot air. The hot air is ultimately discharged out the front of the outer housing 102, providing the user with the desired warm air. This design of the air conditioning device 100 ensures efficient and uniform air heating while also ensuring the safety and stability of the heating element.

[0170] In another embodiment, Figure 5 As shown, the resistance heating device is tubular, specifically a heating tube die-casted integrally with the air guide cover. The heating tube can heat the air guide cover, thereby heating the air flowing on the surface, so as to facilitate the subsequent operation of the wind wheel and blow out warm air.

[0171] It can be understood that when the resistance heating device is selected as the heating wire, the position of the heating wire can be fixed by using a heating bracket, and the heating wire can also be embedded in the air guide cover. When the resistance heating device is selected as the heating tube, the heating tube can also be embedded in the air guide cover and produced through an integrated die-casting processing technology.

[0172] In some embodiments, a heating wire is optionally provided between the impeller 108 and the air guide hood 106. When heating is required, the airflow driven by the rotation of the impeller 108 flows toward the inner wall of the air guide hood 106, where it is heated by the heating wire and eventually discharged outward through the front side of the outer shell 102. The air guide hood 106 is provided within the outer shell 102 to guide the air blown out by the impeller 108 in a specific direction and to maintain the stability of the airflow during the flow.

[0173] In some embodiments, a heating bracket 1042 is optionally provided on the inner sidewall of the air guide hood 106 to secure the heating wire and maintain it in place. This ensures that the heating wire evenly heats the passing air and prevents uneven heat distribution or equipment damage caused by displacement of the heating wire. The design of the heating bracket 1042 generally takes into account heat resistance and structural stability, so that it can withstand high temperatures without deformation.

[0174] The heating wires are mounted on the heating bracket 1042 and primarily convert electrical energy into heat, heating the air blown out by the impeller 108 and passing through the heating wires. The heating wires' material (e.g., nickel-chromium alloy) and electrical resistance properties influence their heating efficiency and lifespan. The heating wires' layout and power design also determine the uniformity and speed of heating.

[0175] As the impeller 108 rotates, it draws in cool air and pushes it toward the air guide hood 106. As the air passes through the heating wires on the heating bracket 1042, it is heated and transformed into hot air. The hot air is ultimately discharged out the front of the outer housing 102, providing the user with the desired warm air. This design of the air conditioning device 100 ensures efficient and uniform air heating while also ensuring the safety and stability of the heating element.

[0176] In some embodiments, optionally, the heating wire can be directly set inside the air guide cover 106, so that the air guide cover 106 can be directly heated, so that after the air contacts the air guide cover 106, it will exchange heat with the air guide cover 106, thereby achieving temperature increase.

[0177] In some embodiments, optionally, the motor 110 in this solution is placed in front, which can reduce the connection length between the motor 110 and the wind wheel 108, thereby reducing the front-to-back distance of the entire air-conditioning device 100.

[0178] Motor rear-mounted

[0179] In some embodiments, optionally, as Figure 8 As shown, the motor 110 in this solution is rear-placed, that is, the position of the motor 110 is set on the axial rear side of the wind wheel 108, so that on the path of air flow, after being heated by the air guide cover 106, it will flow out directly. Compared with the solution with the motor 110 placed in front, the motor 110 itself is not affected by the hot air and the temperature rise can be effectively controlled. On the other hand, since the motor 110 is set on the rear side, the two structures of the air guide cover 106 and the wind wheel 108 are not electrified and can be directly removed and washed with water during cleaning, which greatly reduces the difficulty of cleaning.

[0180] It is understood that the air conditioning device 100 primarily converts electrical energy into thermal and mechanical energy to generate hot air. In this embodiment, by adjusting the relative positions of the motor 110 and the impeller 108 and adding the structure of the air guide 106, air is blown toward the air guide 106 by the impeller 108. The air guide 106 is heated by the heating device 104, thereby increasing the temperature of the air blown toward the air guide 106. Furthermore, the structural features of the air guide 106 allow the air to be directed to the exterior of the air conditioning device 100, thereby providing warm air at a higher velocity.

[0181] In some embodiments, optionally, a first bearing 1122 and a second bearing 1124 are spaced apart. Under the action of the two bearings, the shaft of the wind wheel 108 can be effectively supported and fixed, ensuring the stability and balance of the wind wheel 108 during rotation, while reducing friction and vibration caused by mechanical movement, thereby extending the service life of mechanical components.

[0182] It can be understood that since the motor 110 is set on the rear side of the wind wheel 108, the length of the drive shaft 1102 will be too long. By arranging the first bearing 1122 and the second bearing 1124 at intervals, the rotation of the drive shaft 1102 can be stabilized, the vibration can be reduced, and the rotation stability can be improved.

[0183] In some embodiments, optionally, the coaxial arrangement of the drive shaft 1102, the first bearing 1122, the second bearing 1124 and the wind wheel 108 is to ensure the precise alignment and efficient operation of the entire rotating system. Among them, the drive shaft 1102 is a key component connecting the motor 110 and the wind wheel 108. Its axis is a straight line, which ensures stability and efficiency when transmitting torque. The rotation of the drive shaft 1102 directly affects the rotation speed of the wind wheel 108 and the performance of the wind turbine. The first bearing 1122 and the second bearing 1124 provide support and positioning for the drive shaft 1102, ensuring that the drive shaft 1102 and the wind wheel 108 can operate coaxially, reducing friction and wear during movement, and improving the operating efficiency and stability of the entire system.

[0184] As you can understand, the coaxial arrangement ensures the proper centering of rotating components, reducing vibration and noise, and increasing component life and overall system stability. This design is particularly important for the high-speed rotating rotor 108 system, as even the slightest deviation can significantly degrade performance and accelerate component wear. Precise bearing support and alignment ensure smooth and efficient system operation, providing continuous and stable hot air output.

[0185] The material of the drive shaft 1102 needs to have high strength and good toughness to withstand the force and torque generated during rotation; the diameter and length of the shaft need to be designed according to the size of the wind wheel 108 and the output characteristics of the motor 110.

[0186] The type of bearing (such as deep groove ball bearings, angular contact ball bearings, etc.) should be selected according to the load requirements and installation space; the material of the bearing (such as carbon steel, stainless steel, ceramic, etc.) and the lubrication method (such as oil lubrication, dry lubrication, etc.) should be adapted to the operating environment and temperature conditions.

[0187] It should be noted that the structure of the entire outer shell cover 102 is a fully enclosed structure in the middle, forming a circle of shell, with grilles set in the front and back, among which 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 serve as a part of the front mesh cover 1022 or the rear mesh cover 1024.

[0188] By setting a decorative cover body 1026 between the front mesh cover 1022 and the rear mesh cover 1024, it can be used as the above-mentioned intermediate shell. On the one hand, the appearance of the decorative cover body 1026 can be designed. On the other hand, under the action of the decorative cover body 1026, the user's safety can be improved and the possibility of being burned by the heat of the air guide cover can be reduced. It can be understood that there is a gap between the decorative cover body 1026 itself and the air guide cover. On this basis, an insulating layer is set on the inner side of the decorative cover body 1026, which can further reduce the temperature perceived by the user when touching the decorative cover body 1026, thereby improving the user's usage experience.

[0189] During assembly, the air guide cover 106 and the wind wheel 108 can be assembled together to form a modular structure. The modular structure can be disassembled from the air conditioning equipment 100 as a whole. Since the modular structure does not have any electronic components, it can be directly cleaned with water, which improves the convenience and safety of cleaning.

[0190] It can be understood that the modular structure and the heating device 104 are detachable, and the modular structure and the motor 110 are detachable.

[0191] In some embodiments, optionally, it should be emphasized that a heat dissipation shell 114 accommodating the heating device 104 is provided in the outer shell cover 102. Due to the structural characteristics of the heat dissipation shell 114 itself, air can flow in and out. The electromagnetic heating device 1052 will generate a large amount of heat when in operation. By providing the heat dissipation shell 114, the air can take away the heat of the electromagnetic heating device 1052 when flowing, thereby effectively solving the temperature rise problem of the electromagnetic heating device 1052.

[0192] By disposing the heat dissipation housing 114 between the heating device 104 and the outer cover 102, the front side of the outer cover 102 and the axial rear side of the impeller 108 are connected, thereby guiding the flow of air. When the impeller 108 rotates, air flows from the front side of the outer cover 102 into the heat dissipation housing 114, and then passes through the axial rear side of the impeller 108 and enters the impeller 108.

[0193] It can be understood that the heat dissipation housing 114 ensures that after passing through the heating device 104, the air is effectively guided to the impeller 108 and pushed out by the impeller 108. The second bearing 1124 of the heat dissipation housing 114 helps stabilize the position of the heat dissipation housing 114, reduces vibration and friction, and ensures the stable operation of the heat dissipation housing 114. Overall, the design of the heat dissipation housing 114 helps improve the efficiency and stability of air flow, thereby increasing the performance and reliability of the entire system.

[0194] In some embodiments, thermal insulation brackets 1062 are optionally fixed to heat dissipation housing 114 and disposed on the outside of air scoop 106. The provision of thermal insulation brackets 1062 can, to a certain extent, isolate air scoop 106 from heating device 104, reducing heat conduction to air scoop 106, thereby lowering the temperature of air scoop 106 and improving safety. Furthermore, thermal insulation brackets 1062, being fixed to heat dissipation housing 114, provide additional support and stability for air scoop 106, helping to maintain the stable position of air scoop 106, reducing vibration and friction, and improving the reliability of the entire system.

[0195] By isolating and stabilizing the air guide cover 106, it also helps to improve the working efficiency of the heating device 104. The air between the air guide cover 106 and the heat dissipation shell 114 will flow into the wind wheel 108. Since this part of the air takes away the heat of the electromagnetic heating device 1052, its temperature is higher before flowing into the wind wheel 108, and the heating demand for the air guide cover 106 is relatively small. At this time, the heated air can smoothly enter the wind wheel 108, and then be heated by the air guide cover 106, and finally pushed out by the wind wheel 108.

[0196] In general, the provision of the thermal insulation bracket 1062 in the air conditioning device 100 helps to improve the stability and safety of the system, while also helping to improve the heating efficiency and ensure the normal operation of the entire system.

[0197] In some embodiments, optionally, an assembly method is defined, in which the heat insulation bracket 1062 is connected to the air guide cover 106 and is located on the outside of the air guide cover 106. The heat insulation bracket 1062 is first assembled to the outer shell cover 102 to form a first assembly, and then the heating device 104 is assembled to the first assembly, thereby realizing the installation of the entire air conditioning equipment. For the first assembly, the structures included therein are not electrically charged, so it is easier for users to clean after disassembly, reducing the difficulty of cleaning.

[0198] In some embodiments, optionally, another assembly method is defined, in which the heat insulating bracket 1062 is connected to the air guide cover 106 and is located on the outside of the air guide cover 106. The heat insulating bracket 1062 and the heating device 104 are first assembled to form a second assembly, and then the outer shell cover 102 is assembled to the second assembly. In this solution, the outer shell cover 102 located on the outermost side is assembled last, which is more in line with the user's operating habits during disassembly and reduces the difficulty of disassembly and installation.

[0199] In some embodiments, optionally, a motor bracket 118 is provided at the air outlet end of the air duct 106, mainly for supporting and fixing the motor 110. In addition, it is detachably connected to the air duct 106, which means that the maintenance and replacement of the motor 110 can be more convenient and quick. The design of the motor bracket 118 needs to ensure the stable installation of the motor 110, while being easy to disassemble and maintain. Of course, the motor 110 is mounted on the motor bracket 118, and its drive shaft 1102 is used to drive the wind wheel 108 to rotate. The motor 110 is the power source of the entire air conditioning equipment 100. It transfers kinetic energy to the wind wheel 108 through the drive shaft 1102, so that the wind wheel 108 can rotate and generate airflow. The performance and stability of the motor 110 have an important impact on the working efficiency and stability of the entire equipment.

[0200] Motor 110 drives impeller 108 via drive shaft 1102, generating airflow and pushing it toward air guide hood 106. Simultaneously, heating bracket 1042 and resistance heating device 1054 heat the air, generating hot air. The synergistic effect of these structures enables the handpiece to quickly deliver warm air, meeting user needs. Furthermore, the detachable design of motor bracket 118 facilitates maintenance and repair of the device.

[0201] In some embodiments, optionally, as Figure 7 As shown, the motor bracket 118 is composed of a fixing plate 1182, a ring plate 1184 and a rib 1186. Specifically, the fixing plate 1182 is the main part of the motor bracket 118, which can provide a stable mounting platform for the motor 110. The motor 110 is mounted on the fixing plate 1182, and the fixing plate 1182 needs to have sufficient strength to support the weight of the motor 110 and the vibration generated during operation. The ring plate 1184 is arranged on the radially outer side of the fixing plate 1182, mainly serving as a connecting structure between the fixing plate 1182 and the air guide cover 106, that is, the entire motor bracket 118 is connected to the air guide cover 106 through the ring plate 1184. The ring plate 1184 is designed to cooperate with the air guide cover 106, so that the entire motor bracket 118 can be easily disassembled and connected to the air guide cover 106.

[0202] Furthermore, ribs 1186 are provided to connect the fixing plate 1182 and the ring plate 1184. The design of multiple ribs 1186 reduces wind resistance during airflow and provides additional stability and support. Ribs 1186 form a relatively stable frame structure with the fixing plate 1182 and the ring plate 1184, thereby reducing vibration during operation of the motor 110 and maintaining the structural integrity of the entire bracket.

[0203] It can be understood that through this design, the motor 110 can be securely mounted on the fixing plate 1182. At the same time, the structure of the ring plate 1184 and the ribs 1186 forms a removable and stable connection between the motor bracket 118 and the air scoop 106. This design not only ensures the stability of the motor 110 during operation, but also takes into account the convenience of maintenance and replacement. When the user needs to repair or replace the motor 110, the motor bracket 118 can be easily removed from the air scoop 106 to perform the corresponding operation.

[0204] In some embodiments, a centrifugal impeller 108 is optionally used in the air conditioning device 100, and the drive shaft 1102 of the motor 110 coincides with the axis of the impeller 108. When the centrifugal impeller 108 rotates, the centrifugal force of its blades propels air outward from the center of the impeller 108, and then guides the hot air out through the air guide 106. The centrifugal impeller 108 is suitable for applications that generate a large amount of air flow and a high air pressure, and is often used in equipment that requires a large air volume or that requires the transport of hot air over long distances.

[0205] Furthermore, the alignment of the drive shaft 1102 of the motor 110 with the axis of the rotor 108 ensures that the rotational force of the motor 110 is directly and efficiently transmitted to the rotor 108, reducing energy loss and improving system efficiency. This direct-axis connection also allows for more precise alignment of the motor 110 and rotor 108, helping to reduce vibration and noise, extending the life of the equipment, while also reducing unnecessary structural design and space occupation, thereby improving space utilization.

[0206] It is understood that the use of centrifugal impeller 108 and the alignment of motor 110 drive shaft 1102 with the impeller 108 axis can achieve efficient air flow and heating. The air is driven by centrifugal impeller 108 to generate a high-speed airflow, which is then heated by heating device 104. The resulting hot air is then guided by air guide hood 106 and discharged from the front side of outer housing 102.

[0207] In some embodiments, the outer housing 102 optionally includes a detachably connected front mesh 1022 and rear mesh 1024, which are connected to form a housing for the heating device 104, the air guide 106, the impeller 108, and the motor 110. The front mesh 1022 is provided with a first bearing 1122 for the drive shaft 1102 to pass through. The detachably connected front mesh 1022 and rear mesh 1024 design facilitates maintenance and cleaning of internal components, making repairs more convenient. This is very beneficial for routine maintenance and upkeep of the device.

[0208] The accommodating cavity formed by the connection of the front mesh cover 1022 and the rear mesh cover 1024 provides a suitable space for accommodating the heating device 104, the wind guide cover 106, the wind wheel 108 and the motor 110, so that these internal components can be effectively installed and fixed.

[0209] It should be noted that the structure of the entire outer shell cover 102 is a fully enclosed structure in the middle, forming a circle of shell, namely the decorative cover body 1026, with grilles set in the front and back, among which, 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 serve as a part of the front mesh cover 1022 or the rear mesh cover 1024.

[0210] It should be added that a first bearing 1122 is provided on the front mesh cover 1022 for the drive shaft 1102 to pass through, which helps to support and fix the drive shaft 1102, ensure the stable operation of the drive shaft 1102, and reduce the vibration and friction caused by the movement of the drive shaft 1102.

[0211] In general, the design of the outer shell 102 improves the maintenance convenience of the equipment and the installation stability of the internal components, which is beneficial to the use and maintenance of the entire system.

[0212] Curved Surface Line Design of Air Guide Cover

[0213] In this solution, the air guide cover 106 is a rotating body. On the plane passing through the axis of the air guide cover 106, the size of the air inlet end of the air guide cover 106 is limited to be smaller than the size of the air outlet end of the air guide cover 106, that is, the air guide cover 106 is small at the back and large at the front, and is in the shape of a trumpet, so that after the air is blown out through the wind wheel, it will flow along the inner wall surface of the air guide cover 106, so that the air finally blown out of the air conditioning equipment 100 is in a diffused shape, thereby increasing the air supply area. Under the joint action of the heating device 104 and the air guide cover 106, the effect of warm air over a large area can be achieved.

[0214] Among them, the design of the entire air guide hood 106 is a process of introducing airflow from the air inlet end and gradually heating and accelerating it, and finally discharging it at the air outlet end with a larger volume and higher temperature. This design can maximize the use of the airflow kinetic energy generated by the wind wheel and achieve high-efficiency heat exchange through the heat energy provided by the heating device 104. The contour line design of the air guide hood 106 makes the airflow inside the air guide hood 106 flow more smoothly, reducing energy loss and improving 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 effects in cold environments.

[0215] In some embodiments, optionally, as Figure 4 As shown, the contour lines corresponding to the air guide cover 106 as a rotating body include three types of lines, namely the first line 1072, the second line 1074 and the third line 1076. Specifically, the first line 1072 serves as the starting part of the air inlet end, and the straight line helps to smoothly guide the air into the air guide cover 106, reducing turbulence and airflow loss during air intake. The straight line provides a stable inlet condition, laying a good foundation for the airflow to enter the subsequent curved line area, helping to maintain the stability of the airflow and reduce noise. The second line 1074 serves as the transition part connecting the first line 1072 and the third line 1076. The curved line is usually designed as an arc or other smooth curve to facilitate smooth turning and acceleration of the airflow. The curved line can effectively guide the airflow to concentrate on the air outlet end. At the same time, due to its curvature design, it can accelerate the airflow without generating excessive resistance, thereby increasing the kinetic energy of the airflow. Third profile 1076, serving as the outlet end of air guide 106, is often designed to be wider to accommodate airflow expansion and pressure reduction, while ensuring uniform airflow. By adopting an elliptical or other curved shape, third profile 1076 facilitates smooth airflow diffusion and even heat transfer, resulting in a softer airflow and further increasing the air temperature.

[0216] like Figure 13 As shown in the cross-sectional view, the basic profile of the wind deflector 106 is composed of three curves: Curve 01 (i.e., the first profile), Curve 02 (i.e., the second profile), and Curve 03 (i.e., the third profile). The corresponding endpoints are points a, b, c, and d. The vertical distance between endpoints ab is L1, the vertical distance between endpoints bc is L2, and the vertical distance between endpoint d and the outermost cross-section of the rotor is L3. The minimum distance between Curve 02 and the rotor is L4.

[0217] The design process of the air guide cover 106 is as follows: When designing the air guide cover 106, first determine the starting point b of the curve 02 based on the vertical distance between the leftmost side of the impeller and the inlet of the air guide cover 106 (that is, L1). The value range of L1 is generally 5mm to 40mm. Curve 01 is generally designed as a straight line segment. The position of point c is determined according to the axial width L2 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 L4 (L4 is the minimum distance from curve 02 to the impeller, and the value range is generally 3mm to 12mm). After determining point b, point c and the arc radius, the design of curve 02 can be completed.

[0218] Curve 03 is an elliptical curve that satisfies the equation (xh)² / a² + (yk)² / b² = 1, where (h, k) are the coordinates of the ellipse's center point, and a and b are the lengths of the ellipse's semi-major axis along the x- and y-axes, respectively. The design generally allows the airflow to flow parallel to the axis at point d. Therefore, the outlet diameter W1 is 2a (with the outlet cross-section as the x-axis).

[0219] The position of point d is determined by the distance L3 between the outlet cross section and the rightmost side of the impeller. L3 is generally greater than 5 mm. The semi-major axis length b can then be calculated based on the coordinates of point c. With the ellipse equation, curve O3 can be drawn. 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.

[0220] Finally, the contour line of the air guide cover 106 is rotated and stretched along the central axis to form a curved surface, and then stretched into a solid body according to the structural thickness requirements.

[0221] In some embodiments, optionally, the third profile 1076 serves as the air outlet end of the air guide cover 106, and its elliptical shape helps to gradually expand the flow cross-section of the airflow, which can reduce the airflow velocity and reduce the dynamic pressure at the air outlet while maintaining sufficient static pressure so that the airflow can be discharged smoothly.

[0222] Since the tangent of the third profile 1076 is parallel to the axis of the air guide cover 106, this means that the airflow will not produce additional upward or downward deviation when leaving the air guide cover 106, thereby ensuring the smooth discharge of the airflow, reducing the turbulence and energy loss of the airflow, and helping to improve thermal efficiency and uniformity of air volume.

[0223] The design of the third profile 1076 helps achieve smooth airflow and efficient heat exchange. The elliptical profile allows the airflow to be discharged at the outlet end of the air guide 106 with a larger volume and higher temperature while maintaining a low noise level.

[0224] In some embodiments, optionally, the second profile line 1074 serves as the middle part connecting the first profile line 1072 and the third profile line 1076. The arc line design helps to smoothly guide the airflow from the narrower air inlet end to the wider air outlet end. At the same time, the curvature of the arc can adjust the airflow speed and direction as needed.

[0225] The radius of the arc directly affects the path of the airflow within the air scoop 106. A smaller radius may increase the airflow velocity, but it may also increase the friction between the airflow and the inner wall of the air scoop 106, thereby increasing wind resistance. Conversely, a larger radius can reduce airflow turbulence and friction with the inner wall, thereby reducing wind resistance, but may occupy more space.

[0226] In addition, the minimum distance between the second profile line 1074 and the wind wheel is also a key parameter because it affects the initial conditions of the airflow from the wind wheel into the wind guide cover 106, including the velocity and pressure distribution of the airflow.

[0227] The arc shape of the second profile 1074 and its distance from the wind wheel jointly determine the behavior of the airflow after entering the wind guide cover 106. A reasonable arc radius and minimum distance can ensure a smooth transition of the airflow, reduce energy loss, and improve the overall efficiency of the airflow.

[0228] By optimizing the arc radius and minimum distance of the second profile 1074, a balance point can be found so that the airflow can minimize friction and wind resistance with the inner wall of the air guide cover 106 while maintaining sufficient kinetic energy, thereby improving the overall performance of the heater.

[0229] In some embodiments, the ratio between the maximum diameter of the wind scoop 106 and the maximum diameter of the rotor can be optionally limited to a value between 1.1 and 1.9, which can affect airflow acceleration. It is understood that when airflow enters the wind scoop 106 at the maximum diameter of the rotor, this ratio will affect the degree of airflow acceleration. If the ratio is small, it means that the cross-section of the wind scoop 106 is similar to that of the rotor, and airflow acceleration is not significant. If the ratio is large, the cross-section of the airflow within the wind scoop 106 is further expanded, and the airflow velocity may decrease, but the pressure may increase.

[0230] Furthermore, a larger ratio facilitates pressure recovery within the air scoop 106, which is beneficial for reducing fan power consumption and improving overall system efficiency. Furthermore, a larger diameter of the air scoop 106 provides a larger surface area without increasing resistance, which helps improve heat exchange efficiency and allows the airflow to absorb more heat before leaving the air scoop 106.

[0231] In general, this ratio not only reflects the airflow dynamics and heat exchange characteristics of the air scoop 106 design. An optimized ratio balances fan energy consumption, airflow velocity, pressure distribution, and heat exchange efficiency, thereby improving overall heater performance. It also influences the system's noise level. If the cross-section of the air scoop 106 is too narrow, it may result in excessive airflow and increased noise. A larger cross-section, on the other hand, helps reduce noise, resulting in quieter heater operation.

[0232] In some embodiments, optionally, because the magnetic field distribution of electromagnetic heating device 1052 is closely related to its contour, aligning the contour of air scoop 106 with this contour facilitates the formation of a more uniform magnetic field on the surface of air scoop 106, thereby improving heating efficiency and uniformity. Furthermore, the structure of the rotating body ensures that the heat received by air scoop 106 is evenly distributed, reducing thermal stress and material fatigue caused by uneven heating. It also facilitates smooth airflow, reduces wind resistance, improves airflow efficiency, and allows heated air to be delivered more efficiently.

[0233] Reinforced air guide hood

[0234] like Figure 4 As shown, a raised rib 120 can be directly provided on the inner side wall of the air guide cover 106, or a groove can be formed by digging a groove on the inner side wall. A rib 120 can be formed between two adjacent grooves. The rib 120 extends along a spiral line. Its function is to increase the surface area of ​​the air guide cover 106 without significantly increasing the wind resistance, thereby improving the efficiency of heat exchange. In addition, the spiral rib 120 can also guide the airflow to rotate, enhance the contact between the airflow and the inner wall of the air guide cover 106, and further improve the heating effect and aerodynamic performance. Among them, the groove can also adopt the spiral extension method of the rib. In some implementation methods, it can also be understood that the area between the ribs 120 is a groove. The setting of the groove can also increase the heat exchange area and improve the heat exchange efficiency. The specific implementation method of the groove can refer to the following description of the rib 102.

[0235] It is understood that the air conditioning device 100 primarily converts electrical energy into thermal and mechanical energy to generate hot air. In this embodiment, by adjusting the relative positions of the motor 110 and the impeller 108 and adding the structure of the air guide 106, air is blown toward the air guide 106 by the impeller 108. The air guide 106 is heated by the heating device 104, thereby increasing the temperature of the air blown toward the air guide 106. Furthermore, the structural features of the air guide 106 allow the air to be directed to the exterior of the air conditioning device 100, thereby providing warm air at a higher velocity.

[0236] In some embodiments, optionally, the ribs 120 increase the surface area of ​​the inner wall of the air scoop 106 , thereby increasing the contact area between the passing air and the air scoop 106 , thereby improving the heat exchange efficiency.

[0237] By arranging spaced ribs 120 on the same spiral line, the airflow can be effectively guided and the resistance of the airflow can be reduced, which helps to improve the rotation efficiency and overall aerodynamic performance of the wind wheel 108.

[0238] The number of ribs 120 needs to be sufficient to ensure adequate heat exchange area, but not so great as to excessively increase airflow resistance. Furthermore, the spacing between ribs 120 needs to be carefully designed to maintain good airflow dynamics and heat exchange efficiency. Too little spacing may increase airflow resistance, while too much spacing may reduce heat exchange efficiency.

[0239] Some of the ribs 120 extend along the same spiral line. This arrangement helps to form a continuous airflow path, thereby achieving a better guiding effect.

[0240] In summary, the design of the ribs 120 not only improves heat exchange efficiency, but also optimizes airflow guidance and power performance. By adjusting the number, spacing, and arrangement of the ribs 120, the performance of the entire system can be further adjusted and optimized.

[0241] In some embodiments, optionally, there are multiple spiral lines, each spiral line corresponds to a rib 120, and multiple heat exchange channels can be formed. Such a design can make the overall heat exchange more uniform and the airflow dynamic performance better.

[0242] In some embodiments, only one rib 120 may be provided, resulting in a prominent raised spiral line within the air guide shroud 106. This serves to improve heat exchange efficiency and guide airflow without significantly increasing wind resistance. Rib 120 is provided corresponding to the spiral line, and its shape and path are helical, which helps to create a stable airflow rotation, thereby improving heat transfer and aerodynamic performance.

[0243] In some embodiments, the integrally formed rib 120 and air scoop 106 provide high structural strength because there are no potential weaknesses such as welding or bolting. In addition, the integral stamping process simplifies the production process, reduces assembly steps, and improves manufacturing efficiency and product consistency.

[0244] In some embodiments, the helix pitch and helix angle can be optionally limited separately. Specifically, the pitch can be set within a range of 10 mm to 200 mm. The optimal pitch can be selected based on specific needs and space constraints to achieve optimal heat exchange and airflow guidance. The helix angle ranges from 15° to 80°, and this selection can affect the degree of rotation and speed of the airflow, thereby affecting heat transfer efficiency and aerodynamic performance.

[0245] In some embodiments, optionally, as Figure 5 As shown, the outer peripheral surface of the wind wheel includes a connected closing portion 1082 and an air outlet portion 1084. When the wind wheel rotates, air is blown from the air outlet portion 1084 to the air guide cover. In the axial direction of the wind wheel, the first minimum gap between the rib and the closing portion 1082 is 3mm to 12mm, and in the radial direction of the wind wheel, the second minimum gap between the rib and the closing portion 1082 is 2mm to 10mm.

[0246] The first minimum axial clearance ranges from 3 mm to 12 mm. Selecting a clearance within this range can affect the air flow and resistance between rib 120 and rotor 108, thereby affecting overall aerodynamic performance and heat exchange efficiency. It is understood that a reasonable axial clearance ensures the normal rotation of rotor 108 while also preventing interference from rib 120 on its movement, maintaining system stability and efficiency.

[0247] The second minimum radial clearance ranges from 2 mm to 10 mm. This range also affects the flow and resistance of the airflow, and thus the overall aerodynamic performance and heat exchange efficiency. A reasonable radial clearance ensures full utilization of the space between the rib 120 and the impeller 108, ensuring proper operation of the impeller 108 while maximizing heat exchange efficiency.

[0248] It should be added that the selection of these gap parameters needs to comprehensively consider factors such as space utilization in the axial and radial directions, airflow dynamics and resistance, so as to achieve optimal heat exchange efficiency and aerodynamic performance.

[0249] Reasonable gap design can balance the operational stability of the wind wheel 108, the air flow and resistance between the ribs 120 and the wind wheel 108, thereby achieving optimal performance of the overall design solution.

[0250] In some embodiments, ribs 120 are optionally provided on the inner wall of the air guide hood 106, which can guide the flow of air and increase the heating area. Specifically, the ribs 120 extend in a spiral shape, and the direction of the spiral is consistent with the rotation direction of the wind wheel 108, which can be determined by the right-hand rule. Figure 4As shown, the parameters of the spiral baseline include the pitch S1 and the inlet helix angle α. The pitch S1 ranges from 10 mm to 200 mm, and the inlet helix angle α is determined by the rotation speed of the wind wheel 108 and generally ranges from 15° to 80°.

[0251] The positional relationship between the wind shroud 106 and the impeller 108 requires that the impeller 108 be located within the interior of the wind shroud 106. Under the action of the impeller 108, the air moves forward in a spiral motion, with both an axial forward velocity component and a circumferential rotational velocity component that spreads outward. The circumferential velocity causes the air to strike the wind shroud 106, where it is heated while moving along the shroud 106.

[0252] Furthermore, if Figure 5 As shown, the rib height H ranges from 3mm to 6mm, the width W ranges from 4mm to 8mm, and the spacing L between the ribs ranges from 5mm to 12mm. Since the wind guide 106 is made of ferromagnetic metal, the ribs can be formed by stamping. In order to ensure that the stamped ribs do not interfere with the wind wheel 108 and do not affect the aerodynamic performance, the minimum axial distance between the ribs and the wind wheel 108 must meet the following requirements: 3mm≤S2≤12mm; the minimum radial distance between the ribs and the wind wheel 108 must meet the following requirements: 2mm≤S3≤10mm.

[0253] Thermal insulation structure

[0254] like Figure 6 As shown, in this solution, an insulating layer 121 is provided between the air guide cover 106 and the heating device 104, thereby reducing the impact of the high temperature of the air guide cover on the temperature of the environment in which the heating device is located, improving the safety of use, and also helping to protect the heating device and extend its service life, especially the temperature impact on internal electronic devices and related structural components after being heated by the heating device 104, reducing the occurrence of structural parts or electronic components being damaged due to high temperature.

[0255] The provision of the heat insulating layer can isolate the air guide cover 106 and the heating device 104 to a certain extent, reduce the conduction of heat to the heating device 104, thereby lowering the temperature of the heating device 104 and improving the safety of use.

[0256] In some embodiments, optionally, by directly placing a material with low thermal conductivity outside the air guide cover 106, that is, the heat insulation layer is in the shape of a bracket, forming a Figure 3 and Figure 16 The thermal insulation bracket 1062 shown can prevent heat from being transferred to the other side of the thermal insulation bracket 1062 by the low thermal conductivity of the material itself, thereby ensuring the stable operation of the internal structure.

[0257] It can be understood that by providing the thermal insulation layer 121, the high temperature resistance requirement for the thermal insulation bracket 1062 can be reduced, which is beneficial to reducing costs.

[0258] Among them, the air guide cover 106 is fixed to other structures by the heat insulation bracket 1062, and can be directly fixed to the outer shell cover 102, or fixed to the heating device 104. The heat insulation bracket 1062 can serve as the bracket structure of the air guide cover 106 to achieve positioning.

[0259] It can be understood that in this solution, the air guide cover 106 is arranged in the outer shell cover 102, and the relative position restriction with the outer shell cover 102 can be achieved by the insulation layer 121, that is, the insulation layer 121 fixes the position of the air guide cover 106 in the outer shell cover 102.

[0260] In some embodiments, multiple insulating air chambers 122 are optionally provided between the air scoop 106 and the heating device 104. The structure of the insulating air chambers 122, when filled with gas, can achieve physical insulation. Specifically, the insulating properties of the insulating air chambers 122 can be utilized to block heat transfer from the air scoop 106 to the insulating support 1062. Furthermore, any two adjacent insulating air chambers 122 are separated by ribs. Multiple insulating air chambers 122 may be provided. Each insulating air chamber 122 can be arranged on the insulating support 1062.

[0261] In some embodiments, optionally, an insulating medium with low thermal conductivity is filled in the insulating air chamber 122 to form a continuous insulating structure, thereby effectively reducing heat conduction and ensuring the normal use of the insulating bracket 1062 and related electronic components or mechanical structures.

[0262] Alternatively, the insulating medium is air. When heated, its volume expands and its density decreases, causing hot air to rise and cold air to sink (natural convection). In the case of convection, heat is primarily transferred through convection, which greatly reduces the insulating effect of air. Therefore, the most important thing to do when using air for insulation is to limit its movement.

[0263] It is understandable that the smaller the size of the air chamber, the more difficult it is for the air to flow, and the better the thermal insulation performance. However, considering the manufacturability of the structural parts, it is sufficient to produce air chambers of millimeter or centimeter size.

[0264] A heat insulating layer may be provided on the heat dissipation housing 114 and also provided on the outside of the air guide cover 106 , isolating the air guide cover 106 and the heating device to a certain extent.

[0265] It is important to emphasize that the thermal insulation bracket 1062 is fixed to the heat dissipation housing 114 and is disposed on the outside of the air scoop 106. The provision of the thermal insulation bracket 1062 can, to a certain extent, isolate the air scoop 106 from the heating device 104, reducing the conduction of heat to the air scoop 106, thereby lowering the temperature of the air scoop 106 and improving its safety. Furthermore, the thermal insulation bracket 1062, fixed to the heat dissipation housing 114, provides additional support and stability for the air scoop 106, helping to maintain the stable position of the air scoop 106, reducing vibration and friction, and improving the reliability of the entire system.

[0266] By isolating and stabilizing the air guide cover 106 , it also helps to improve the working efficiency of the heating device 104 , ensuring that the heated air can smoothly enter the heat dissipation housing 114 and then be pushed out by the wind wheel 108 .

[0267] In general, the provision of the thermal insulation bracket 1062 in the air conditioning device 100 helps to improve the stability and safety of the system, while also helping to improve the heating efficiency and ensure the normal operation of the entire system.

[0268] In some embodiments, optionally, as Figure 6 As shown, a plurality of insulating air chambers 122 are provided on the insulating bracket 1062, and dense small air chambers can be separated by the structure. After installation, air is trapped inside the insulating air chamber 122. Use air as a thermal insulation material. When air is stationary, it is a very good thermal insulation material (low thermal conductivity), but as a fluid, its volume will expand when heated, and its density will decrease, so that hot air rises and cold air settles (natural convection). In the case of convection, heat is mainly transferred through convection, resulting in a significant reduction in the thermal insulation effect of air. Therefore, the most important thing when using air for insulation is to limit the flow of air.

[0269] It should be added that the smaller the size of the air chamber, the more difficult the air flow is and the better the thermal insulation performance is.

[0270] Purifier

[0271] It should be emphasized that if Figure 14 As shown, a purification component 130 is provided on the inner side of the air guide cover 106. When the air flows, it will pass through the purification component 130 for purification. Since the purification component 130 is located on the inner side of the air guide cover 106, when the air is discharged outward, the structure of the air guide cover 106 can be utilized to enhance the air outlet distance, so that the overall air flow range of the space where the air conditioning equipment is located is larger, thereby improving the purification effect.

[0272] When the temperature of the air guide cover 106 itself rises, the temperature of the environment in which the purification component 130 is located will be heated. As the temperature rises, the flow of air will become more active, which can improve the purification effect. On the other hand, as the temperature changes, if a catalyst is used, the catalyst can be used to catalyze the decomposition of polluted gases in different temperature ranges to achieve more effective purification.

[0273] In some embodiments, optionally, as Figure 15 As shown, the purification element 130 is a negative ion generator. The negative ions generated can react with particulate matter, bacteria, etc. in the air, causing them to settle or condense, thereby purifying the air. In addition, the negative ion generator is placed in the outer shell 102, with one end extending through the air guide 106 into the space between the air guide 106 and the wind wheel 108. This allows the negative ions to come into contact with the air more fully, enhancing the purification effect.

[0274] In some embodiments, optionally, as Figure 14 As shown, the purification element 130 is arranged on the inner wall surface, that is, the purification element is in the form of a film and can be arranged on the inner wall surface of the air guide cover 106 in the form of a coating. When the air passes through the inner wall surface of the air guide cover 106, the purification effect of the coating can purify the pollutants in the air, improve the quality of the air, and achieve the effect of purifying the air.

[0275] Optionally, the coating may be provided on the inner surface of the air guide hood 106 by spraying, chemical coating, or chemical growth.

[0276] It can be understood that spraying is a process in which a material (usually liquid or powder) is sprayed through a nozzle at high speed onto the surface of a substrate to form a coating. Chemical coating refers to the process of forming a thin film on the surface of a substrate using a chemical reaction. These chemical reactions can be electrodeposition (electroplating), chemical vapor deposition (CVD), chemical solution deposition, etc. Chemical growth generally refers to the process in which a material grows on a substrate through a chemical reaction, such as chemical vapor deposition (CVD) and atomic layer deposition (ALD). Similar to chemical coating, chemical growth can achieve high-precision and high-quality thin films, but it focuses more on growing materials layer by layer by controlling chemical reactions to achieve nanometer-level thickness control.

[0277] In some embodiments, the catalyst coating in the purification element is optionally a key purification component, which is divided into multiple purification zones according to location. Each purification zone may contain one or more catalysts, which are designed to activate at different temperatures to decompose specific types of pollutants. For example: low-temperature catalysts are used to decompose volatile organic compounds (VOCs). Medium-temperature catalysts are specifically used to decompose nitrogen oxides (NOx). High-temperature catalysts are used to decompose particulate matter (PM) and other difficult-to-decompose chemicals.

[0278] Electromagnetic induction heating technology enables air scoop 106 to reach the temperature required by different catalysts, thereby activating the catalysts and improving purification effectiveness. This design allows the air flow generated by impeller 108 to be effectively utilized without increasing additional energy consumption, purifying the air through the catalyst layer at the appropriate temperature, thereby improving the overall effectiveness and purification efficiency of the system.

[0279] In some embodiments, multiple purification zones are optionally provided along the thickness of the air scoop, including at least a first purification zone and a second purification zone, to achieve purification of a variety of impurities. It is understood that the heat from the air scoop can increase the temperature of the catalyst, thereby improving catalytic efficiency. Since heat decreases with increasing distance, the catalyst within the purification zone closer to the inner wall of the air scoop will be at a higher temperature, allowing multiple catalysts with different catalytic temperatures to be catalyzed simultaneously. That is, when the first purification zone is closer to the inner wall of the air scoop, the catalytic temperature of the catalyst in the first purification zone is higher, thereby improving the catalytic effect.

[0280] It should be added that the change in the catalytic temperature of multiple purification zones can be linear or nonlinear, as long as the catalytic temperatures of the catalysts in two purification zones are different, and the catalytic temperature in one purification zone close to the inner wall of the air guide hood is greater than the catalytic temperature in another purification zone that is farther away, it is within the protection scope of this application.

[0281] For example, a low-temperature catalyst is placed in the purification zone farthest from the air scoop to decompose volatile organic compounds (VOCs), while a high-temperature catalyst is placed in the purification zone closest to the air scoop to decompose particulate matter (PM) and other difficult-to-decompose chemicals.

[0282] In some embodiments, multiple purification zones are optionally provided on the same floor, including at least a first purification zone and a second purification zone, and the multiple purification zones are arranged in different zones on the same floor, thereby achieving purification of multiple impurities. It is understandable that for air conditioning equipment, the temperature at the air inlet is lower, and the temperature at the air outlet is higher than that at the air inlet. Therefore, the temperature difference can be utilized to enable multiple catalysts to act simultaneously, thereby improving catalytic efficiency. The closer the purification zone is to the air inlet of the air duct, the lower the temperature of the catalyst inside it will be. That is, when the first purification zone is closer to the air inlet of the air duct, the catalytic temperature of the catalyst in the first purification zone is lower, thereby improving the catalytic effect.

[0283] It should be added that the change in the catalytic temperature of multiple purification zones can be linear or nonlinear, as long as the catalytic temperatures of the catalysts in two purification zones are different, and the catalytic temperature in one purification zone close to the air inlet end of the air guide hood is lower than the catalytic temperature in another purification zone at a farther distance, it is within the protection scope of this application.

[0284] For example, a low-temperature catalyst is placed in the purification zone farthest from the air inlet of the air scoop to decompose volatile organic compounds (VOCs). A high-temperature catalyst is placed in the purification zone closest to the air inlet of the air scoop to decompose particulate matter (PM) and other difficult-to-decompose chemicals.

[0285] "humidifier"

[0286] In some embodiments, the air treatment device of the present invention optionally also has a humidification function, specifically, it further includes a water outlet device 140, the water outlet device 140 is used to generate a humidification medium flowing toward the inner wall surface of the air guide cover 106, and the humidification medium includes one of the following or a combination thereof: water, water droplets, mist. Figure 17 and Figure 18 As shown, the water outlet device 140 includes a water tank 1402 and an atomizing device 1404. The water tank is arranged on the air inlet side so that after the water droplets or water mist are generated by the atomizing device, they can flow smoothly into the air flow regulating component, under the action of which the air guide hood is used to achieve diversion and temperature increase. It should be added that the water tank 1402 is usually used to store the water required by the water outlet device 140. Factors such as its volume, material, location and sealing performance will affect the humidification effect and the service life of the equipment. The atomizing device 1404 is located inside the water tank 1402 and converts the water in the water tank 1402 into fine water droplets or water vapor for better distribution and absorption.

[0287] The atomization device 1404 may use ultrasonic atomization technology or other atomization methods.

[0288] In some embodiments, the atomizing device 1404 is optionally disposed at the bottom of the water tank 1402, and the space of the water tank 1402 can be utilized so that the atomizing device 1404 can better generate water vapor and release it into the air through the air outlet at the top. The water droplets and / or water mist flowing out of the air outlet rotates through the wind wheel and flows toward the inner wall surface of the wind guide cover 106. This design will improve the uniform distribution and release efficiency of water vapor.

[0289] It should be noted that due to the design of the bottom position, the water vapor can be released more fully into the water tank 1402, making the water vapor generation more uniform. The air outlet at the top of the water tank 1402 allows the atomized water vapor to be smoothly released into the external environment. This helps to maintain the humidity inside the water tank 1402 and also enables the water vapor to be effectively transported to the area that needs humidification.

[0290] In some embodiments, the water outlet device 140 optionally includes a nozzle that discharges water toward the inner wall of the air guide hood. Under the action of the nozzle, the humidification medium can flow directly into the air guide hood 106 without being driven by the air flow control component. The heating device heats the air guide hood, causing the temperature of the humidification medium to change, thereby achieving temperature control of the outlet air humidification.

[0291] In some embodiments, the water outlet device 140 is optionally arranged on the outside of the airflow adjustment component, so that the outside air is mixed with the water vapor generated by the water outlet device 140, and flows into the wind guide cover 106 after the rotation of the wind wheel, thereby achieving a humidification effect. This design will increase the humidity of the air. In addition, since the blown air will heat up after passing through the wind guide cover 106, the ambient temperature may also change locally.

[0292] In addition, if Figure 16 and Figure 17 As shown, by setting a water outlet device 130 on the rear mesh cover 1024, when the wind wheel rotates, air flows in from the water outlet device side, flows along the wind guide cover after being humidified, and finally discharges the humidified air.

[0293] In general, the design of the outer shell 102 improves the maintenance convenience of the equipment and the installation stability of the internal components, which is beneficial to the use and maintenance of the entire system.

[0294] This application proposes another embodiment of a heater 200, such as Figure 9 As shown, the air conditioner 100 and the base bracket 202 are detachably connected. The base bracket 202 is detachably connected to the air conditioner 100. This design facilitates assembly and disassembly of the device, making it more flexible and easy to transport and maintain. The base bracket 202 provides a firm support, helping to maintain the stability of the entire heater 200, reducing shaking and wobbling during operation, and improving the safety and reliability of the device.

[0295] In addition, since the base bracket 202 is detachably connected to the air conditioning device 100, different air conditioning devices 100 can be selected as needed, making the heater 200 more widely applicable and flexible.

[0296] This application also provides a control method, such as Figure 19 As shown, it includes step S202: in response to the warm air start instruction, the wind wheel is controlled to rotate, and a part of the air flows into the air inlet side of the wind wheel from the rear side of the outer shell cover; step S204: according to the warm air start instruction, the heating device is controlled to operate, and under the action of the wind wheel, the air is radially discharged to the inner wall surface of the air guide cover, the air is heated by the air guide cover and guided to the air outlet side of the outer shell cover, and discharged outward.

[0297] The control method of this solution effectively generates a large volume of hot air, effectively heating the space. Specifically, the entire process begins by controlling the rotation of the impeller in response to a warm air start command. This command is typically issued by the user through a controller (such as a remote control or smart home system), and the impeller's rotation is driven by a motor. The impeller's function is to draw in air and propel it forward. Due to the device's design, some air is drawn from the outside into the impeller's inlet side. Simultaneously, the impeller's rotation creates a negative pressure on the air duct on its inlet side—a pressure lower than the ambient pressure—which helps draw in more air. Under this negative pressure, another portion of air is drawn into the impeller's inlet side through a specific heat dissipation housing. This design allows for more effective control of air flow direction and volume. Furthermore, upon a start command, the heating device begins operating. This is typically achieved using an electric heating element (such as a heating wire) or electromagnetic heating principles. Under the action of the impeller, air is pushed radially (from the center outward) and heated as it passes through the air scoop. The air scoop not only heats the air but also directs it in a designated direction. Finally, the heated air is exhausted through the outlet side of the housing, distributing the heat to the room. This process not only increases the room temperature but also helps circulate the air.

[0298] The effect of the entire process is to convert cold air into hot air and distribute the hot air evenly into the environment, thereby achieving the purpose of heating and improving comfort.

[0299] In a specific embodiment, a heater structure with IH side wall heating is proposed, and the whole structure includes a motor 110, a front mesh cover 1022, a wind wheel 108, an outer shell (i.e., an outer shell cover 102), a heating plate (i.e., an air guide cover 106), a heating plate bracket (i.e., a heat insulation bracket 1062), a coil disk bracket (i.e., a heating bracket 1042), an air duct (i.e., a heat dissipation shell 114), and other structures. The overall solution adopts a centrifugal fan (i.e., a wind wheel 108 + a motor 110) as a power pack. The centrifugal fan has the characteristics of axial air inlet and radial air outlet, and the outlet airflow is thrown out under the action of centrifugal force. The side wall of the power pack is made of magnetic metal parts and is heated by electromagnetic induction. During operation, the airflow is heated by passing through the heated side wall, thereby realizing the warm air function.

[0300] The overall structure of the machine is arranged as follows. First, the heating plate must be made of a metal that can conduct magnetism (conventional ones include 430 stainless steel, iron, etc.). When working, the heating plate will generate heat due to the effect of electromagnetic induction. The heating plate is fixed on the heating plate bracket. The heating plate bracket is usually made of high-temperature resistant plastic parts (such as nylon) or ceramics and other materials. The heating plate bracket usually plays two roles. The first is to fix the heating plate, and the second is heat insulation. Since the temperature of the heating plate is extremely high when working, conventional electronic devices cannot withstand such a temperature, so it needs to be wrapped on the outside with a plastic bracket to play a certain heat insulation role. There is a coil disk bracket on the outside of the heating plate bracket. An electromagnetic coil is wound on the coil disk. When powered on, an alternating magnetic field is generated, thereby heating the heating plate.

[0301] Conventional IH solenoid coils are typically made of copper or enameled wire, with an overall temperature resistance of around 150°C (due to the insulation varnish failing and causing a short circuit). However, when operating at full power, the coil temperature can easily exceed the specified temperature limit. Furthermore, the heater's heating element reaches extremely high temperatures, often exceeding 400°C. Furthermore, the spacing between the coil and the heating element cannot be too large (to account for electromagnetic coupling, typically between 5mm and 20mm). This results in extremely high internal temperatures within the heater, even with insulation. The coil's operating environment is extremely demanding, necessitating the design of a separate air duct to dissipate heat. The underlying design concept involves creating separate channels through structural components, either above and below the coil (for flat coils) or inside and outside (for toroidal coils). Cool air is introduced at one end, flowing parallel to the coil, passing over the coil's upper and lower surfaces, removing heat. Once the airflow heats up, it is discharged through an outlet at the other end. Because the airflow is parallel to the coil reel, the heat dissipation resistance is relatively low, making this method highly efficient in dissipating heat.

[0302] The heating plate bracket and the coil disc bracket are fixed together on the heat dissipation shell. The heat dissipation shell mainly plays two roles. The first is to form a heat dissipation duct, and the second is to play the role of fastening the supporting structure. The fixation of other structural parts is relatively conventional. The wind wheel is fixed to the motor, the motor is fixed to the motor bracket, the motor bracket is fixed to the heat dissipation shell, the heat dissipation shell is fixed to the outer shell, and finally the front mesh cover is fixed to the outer shell to form a complete machine. The heat dissipation system is integrated into the overall machine through structural design. The airflow state of the whole machine is as follows Figure 3 As shown. When the impeller rotates, a negative pressure area is formed behind the impeller, and the negative pressure area attracts airflow. When the uppermost airflow is sucked in through the gap between the air duct and the coil disk, the cold air takes away the heat from the coil disk, thereby dissipating the heat from the coil disk. This design uses the negative pressure of the centrifugal power pack to inhale cold air, eliminating the need for an additional fan to blow cold air into the heat dissipation duct. At the same time, since the cold air first dissipates heat from the coil disk after being introduced, the airflow temperature rises, and then it is introduced into the main air duct and heated again by the heated side wall, so the heat is effectively utilized. This is an efficient and ingenious method.

[0303] In another embodiment, an independent fan is provided at one end of the heat dissipation duct to blow cold air into the duct or to suck out the hot air after heat dissipation, which can also effectively solve the problem of coil temperature rise.

[0305] According to the air conditioning equipment and heater provided by the present invention, strong airflow can be generated under the action of the airflow adjustment component. These airflows are heated when passing through the heated air guide cover and are finally discharged from the front side of the machine head, thereby achieving the effect of large air volume and warm air output.
