Description

TECHNICAL FIELD

[0001] The utility model relates to a warm air blower technical field, specifically, an air outlet equipment and a warm air blower. BACKGROUND

[0002] At present, a part of users usually use the warm air blower to heat, in the related art, the motor driving the fan to rotate can be placed at the air inlet position of the fan or can be placed at the air outlet position of the fan, since considering that air flows into the rear side of the shaft of the fan, a part of air inlets will be affected, leading to the increase of air inlet resistance, so that the motor of the fan is placed at the air outlet position of the front side, but the temperature blown out by the warm air blower is higher, so that the motor is always in a higher environment temperature, which has a certain influence on the working efficiency of the motor. SUMMARY

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

[0004] Therefore, the utility model provides an air outlet equipment in a first aspect of embodiments.

[0005] The utility model provides a warm air blower in a second aspect of embodiments.

[0006] In order to realize the above-mentioned purpose, the utility model provides an air outlet equipment in a first aspect of embodiments, comprising: a shell cover;A heating device is arranged at the inner side of the shell cover;A wind scooper is arranged correspondingly with the heating device, and the heating device is used for heating the wind scooper;A fan wheel is arranged in the inside of the wind scooper, and the fan wheel rotates and blows air towards the inner wall surface of the wind scooper, and the air is discharged outward from the front side of the shell cover after being guided by the wind scooper;A motor is arranged at the rear side of the fan wheel along the axial direction of the fan wheel, and the motor is in transmission connection with the fan wheel to drive the fan wheel to rotate.

[0007] The air outlet equipment provided by the utility model mainly comprises a shell cover and a heating device, a wind scooper, a fan wheel and a motor arranged in the shell cover. Specifically, the shell cover provides a firm protective housing for the air outlet equipment, which not only protects the internal structure from damage, but also plays a heat insulation role to ensure the safety of the user during use. The heating device is the core of the air outlet equipment, responsible for converting electrical energy into heat energy. The heating device is arranged correspondingly with the wind scooper, and the heating device can increase the temperature of the wind scooper. Specifically, the heating element can be composed of high-temperature-resistant resistance wire, or higher-efficiency PTC ceramic materials can be used, or even electromagnetic coils can be used. The specific shape design should be beneficial to the uniform distribution of air flow and heat exchange efficiency. The fan wheel is located in the wind scooper, and its rotation will generate strong airflow. These airflows are heated when passing through the heated wind scooper, and finally discharged from the front side of the machine head under the guiding action of the wind scooper. The motor is located at the rear side of the fan wheel and can provide power to make the fan wheel rotate.

[0008] It is emphasized that the motor in the present scheme is rear-mounted, i.e. the position of the motor is set at the axial rear side of the wind wheel, so that in the path of air flow, after being heated by the air deflector, it will directly flow out. Compared with the scheme of front-mounted motor, the motor itself is not affected by the hot air, and the temperature rise can be effectively controlled. On the other hand, since the motor is set at the rear side, the air deflector and the wind wheel are not electrified, and can be directly removed and washed during cleaning, greatly reducing the cleaning difficulty.

[0009] It can be understood that the air outlet device can mainly convert electrical energy into heat energy and mechanical energy to generate hot air. In the present scheme, by adjusting the relative position of the motor and the wind wheel, and increasing the structure of the air deflector, the air will be blown to the air deflector under the action of the wind wheel. The air deflector is heated by the heating device to increase the temperature of the air blown to the air deflector. At the same time, the air is guided to the outside of the air outlet device by the structural characteristics of the air deflector itself, thereby providing warm air with a larger wind speed. It should be added that although the motor is arranged at the air inlet position, the overall air volume can still meet the user's demand under the overall action of the motor, the wind wheel and the air deflector.

[0010] It should be added that the motor type can be a direct current or alternating current motor, or even a brushless motor to improve efficiency and reduce maintenance; the power and speed of the motor should be matched with the design of the wind wheel; and the heat dissipation design of the motor should ensure that it will not overheat during long-time operation.

[0011] In some technical schemes, the wind wheel is a centrifugal wind wheel, the motor is arranged at the rear side of the wind wheel along the axial direction of the wind wheel, the drive shaft of the motor penetrates the wind wheel, the drive shaft is used to drive the wind wheel to rotate, air is inhaled from the axial rear side of the centrifugal wind wheel and is blown radially towards the air deflector.

[0012] In the present scheme, the wind wheel is selected as a centrifugal wind wheel, and the air inlet direction and the air outlet direction are not parallel, so as to facilitate the air inlet at the rear side of the entire air outlet device when the wind wheel is arranged in the air deflector. Under the action of the centrifugal wind wheel, the air is blown radially towards the air deflector, and then guided by the air deflector, and finally realized as air outlet at the front side of the entire air outlet device in the axial direction. That is to say, for the air outlet device, the air flow direction is still rear air inlet and front air outlet, but due to the arrangement of the centrifugal wind wheel, the front-to-rear dimension of the entire product is small, and at the same time, a high wind speed can be maintained under the action of the centrifugal wind wheel, thereby improving the air supply distance.

[0013] In some technical schemes, the first bearing and the second bearing are arranged at two sides of the wind wheel in the axial direction of the wind wheel, and the drive shaft penetrates the first bearing and the second bearing.

[0014] In the technical solution, the first bearing and the second bearing are arranged at intervals, and under the action of the two bearings, the shaft of the wind wheel can be effectively supported and fixed, ensuring the stability and balance of the wind wheel during rotation, while reducing friction and vibration caused by mechanical movement, thereby prolonging the service life of mechanical components.

[0015] It should be noted that the first bearing and the second bearing can be fixed on the shell cover or on a structure fixed relative to the position of the shell cover.

[0016] It can be understood that, since the motor is arranged at the rear side of the wind wheel, the length of the drive shaft may be too long. By arranging the first bearing and the second bearing, the rotation of the drive shaft can be stabilized, the shaking can be reduced, and the rotation stability can be improved.

[0017] In some technical solutions, the axis of the drive shaft is a straight line, and the first bearing, the second bearing, and the wind wheel are coaxially arranged.

[0018] In the technical solution, the coaxial arrangement of the drive shaft, the first bearing, the second bearing, and the wind wheel is to ensure the accurate centering and efficient operation of the entire rotating system. The drive shaft is a key component connecting the motor and the wind wheel, and its axis is a straight line, ensuring the stability and efficiency of torque transmission. The rotation of the drive shaft directly affects the rotational speed of the wind wheel and the performance of the fan. The first bearing and the second bearing provide support and positioning for the drive shaft, ensuring that the drive shaft and the wind wheel can operate coaxially, reducing friction and wear during movement, and improving the operating efficiency and stability of the entire system.

[0019] It can be understood that the coaxial arrangement ensures the centering of the rotating components, reduces vibration and noise, and improves the life of the rotating components and the stability of the entire machine. This design is particularly important for high-speed rotating wind wheel systems, as any slight deviation can lead to significant performance degradation and accelerated component wear. Through precise bearing support and centering, the system can achieve smooth and efficient operation, thereby providing continuous and stable hot air output.

[0020] The material of the drive shaft 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 and the output characteristics of the motor.

[0021] The type of bearing (such as deep groove ball bearing, angular contact ball bearing, etc.) is selected according to the bearing requirement 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 adapt to the operating environment and temperature conditions.

[0022] In some embodiments, the air duct shell is arranged between the heating device and the outer shell cover, and a second bearing is arranged on the air duct shell; the air duct is formed between the air duct shell and the air guide cover, and the air flows into the air wheel through the air duct when the air wheel rotates.

[0023] In this embodiment, the air duct shell is arranged between the heating device and the outer shell cover, and the air duct shell provides an air inlet path for the air wheel. Specifically, the air duct is formed between the air duct shell and the air guide cover, and the outlet of the air duct is arranged opposite to the air inlet side of the air wheel. For the entire air conditioning device, there can be one or more air inlets of the air duct, and the position of the inlet can be flexibly arranged to improve the air volume.

[0024] It can be understood that under the action of the air duct shell, the air can be effectively guided to the air wheel after flowing through the heating device and pushed out by the air wheel. The second bearing arranged on the air duct shell helps to stabilize the position of the air duct shell, reduces vibration and friction, and ensures stable operation of the air duct shell. Overall, the design of the air duct shell is beneficial to improve the efficiency and stability of air flow, thereby increasing the performance and reliability of the entire system.

[0025] In some embodiments, at least part of the air wheel is arranged inside the air guide cover.

[0026] By limiting part of the air wheel or all of the air wheel to be arranged inside the air guide cover, the air driven by the rotating air wheel can be fully directed to the air guide cover, and the air can be heated and exchanged with the air guide cover, and then blown out under the guidance of the air guide cover, thereby realizing the blowing of hot air.

[0027] In some embodiments, the heating device specifically comprises a heating bracket arranged outside the air guide cover, the heating bracket is fixed on the air duct shell, and an electromagnetic coil is arranged on the heating bracket.

[0028] In this embodiment, the heating device mainly comprises a heating bracket, which is arranged corresponding to the air guide cover and outside the air guide cover, and is fixed on the air duct shell. This helps to ensure the effective cooperation of the heating bracket and the air guide cover, and provides a stable support structure. In addition, the heating bracket can be in the form of a disc, i.e. a coil disc, and an electromagnetic coil is arranged on the coil disc. When the electromagnetic coil is energized, an alternating magnetic field is generated, which enables the air guide cover to realize electromagnetic induction heating, thereby providing an efficient way for air heating.

[0029] In some embodiments, the air duct shell is arranged between the heating device and the outer shell cover, and a second bearing is arranged on the air duct shell; the air duct is formed between the air duct shell and the air guide cover, and the air flows into the air wheel through the air duct when the air wheel rotates.

[0030] In this technical solution, the heat insulation support is fixed on the air duct shell and is arranged outside the air guide cover. The arrangement of the heat insulation support can isolate the air guide cover and the heating device to some extent, reduce the conduction of heat to the air guide cover, thereby reducing the temperature of the air guide cover and improving the safety of use. In addition, the heat insulation support is fixed on the air duct shell, which provides additional support and stability for the air guide cover, helps to keep the position of the air guide cover stable, reduces vibration and friction, and improves the reliability of the entire system.

[0031] By isolating and stabilizing the air guide cover, the working efficiency of the heating device is also improved, ensuring that the heated air can smoothly enter the air duct shell and then be pushed out by the fan wheel.

[0032] Overall, the arrangement of the heat insulation support in this air outlet device helps to improve the stability and safety of the system, and also helps to improve the heating efficiency and ensure the normal operation of the entire system.

[0033] In some technical solutions, the heating device is an electromagnetic coil, the material of the air guide cover is a magnetic conductive material, and the heating device and the air guide cover are arranged at intervals.

[0034] In this technical solution, an electromagnetic coil is used as the heating device, the material of the air guide cover is a magnetic conductive material, and an interval is arranged between the heating device and the air guide cover. By using an electromagnetic coil as the heating device, electromagnetic induction heating can be achieved, which has the advantages of uniform heating, fast response, etc., which is beneficial to improve the heating efficiency and control the heating temperature. In addition, the air guide cover is made of a magnetic conductive material, which helps to guide the heat field, improves the thermal efficiency, reduces energy loss, ensures that the heated air can be effectively introduced into the air duct shell, and improves the utilization rate of hot air. It should be added that the interval between the heating device and the air guide cover helps to reduce the temperature of the air guide cover, reduce the conduction of heat to the air guide cover, improve the safety of use, and also helps to protect the heating device and prolong its service life.

[0035] In some technical solutions, the shell cover includes a detachably connected front mesh cover and a rear mesh cover, and the front mesh cover and the rear mesh cover are connected to form a containing cavity containing the heating device, the air guide cover, the fan wheel and the motor. The first bearing is arranged on the front mesh cover for the driving shaft to pass through.

[0036] In this technical solution, the shell cover includes a detachably connected front mesh cover and a rear mesh cover, and the front mesh cover and the rear mesh cover are connected to form a containing cavity containing the heating device, the air guide cover, the fan wheel and the motor. The first bearing is arranged on the front mesh cover for the driving shaft to pass through. The detachable connection of the front mesh cover and the rear mesh cover facilitates the maintenance and cleaning of the internal components, making maintenance more convenient. This is very beneficial for the daily maintenance and maintenance of the equipment.

[0037] The accommodating cavity formed by the front mesh cover and the rear mesh cover provides suitable space for arranging the heating device, the air guide cover, the air wheel and the motor, so that these internal components can be effectively installed and fixed.

[0038] It should be noted that the first shaft bearing is arranged on the front mesh cover for the driving shaft to pass through, which helps to support and fix the driving shaft, ensures stable operation of the driving shaft, and reduces vibration and friction caused by movement of the driving shaft.

[0039] In general, the design of the shell cover improves the maintenance convenience of the equipment and the installation stability of the internal components, which is conducive to the use and maintenance of the entire system.

[0040] In some technical solutions, optionally, the air guide cover and the air wheel are assembled to form a modular structure, the modular structure is detachably connected with the heating device, and / or the modular structure is detachably connected with the motor.

[0041] In this scheme, the air guide cover and the air wheel can be assembled together to form a modular structure when assembled, and the modular structure can be integrally detached from the air outlet equipment. Since the modular structure does not have any electronic devices, it can be directly cleaned with water, thereby improving the convenience and safety of cleaning.

[0042] It can be understood that the modular structure is detachable from the heating device, and the modular structure is detachable from the motor.

[0043] In some technical solutions, optionally, the heating device is an electric heating wire, the material of the air guide cover is a heat-conducting material, and the heating device is arranged on the air guide cover.

[0044] In this technical solution, the electric heating wire is used as the heating device, which can quickly generate heat, and the air guide cover made of heat-conducting material helps to quickly conduct the heat, thereby improving the heating efficiency and enabling the heated air to be quickly sent to the air duct shell.

[0058] ​​In order to enable the above-mentioned purposes, features and advantages of the embodiments of the present application to be more clearly understood, the embodiments of the present application will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present application can also be implemented in other different manners from those described herein, therefore, the protection scope of the present application is not limited to the specific embodiments disclosed below.

[0060] The following description refers to the accompanying drawings that show Figures 1 to 5 described according to some embodiments of the present application.

[0061] As Figure 1 and Figure 2 shown, the air outlet device 100 proposed in the present embodiment mainly comprises a shell cover 102 and a heating device 104, an air guide cover 106, a fan wheel 108 and a motor 110 arranged in the shell cover 102. Specifically, the shell cover 102 provides a solid protective housing for the air outlet device 100, which not only protects the internal structure from damage, but also plays a role in heat insulation and insulation to ensure the safety of the user when using. The heating device 104 is the core of the air outlet device 100, which is responsible for converting electrical energy into heat energy. The heating device 104 is placed corresponding to the air guide cover 106, and the heating device can make the temperature of the air guide cover rise. Specifically, the heating element can be composed of high-temperature-resistant resistance wire, or more efficient PTC ceramic and other materials, or even electromagnetic coil. The specific shape design should be beneficial to the uniform distribution of air flow and heat exchange efficiency. The fan wheel 108 is located in the air guide cover 106, and its rotation will produce strong airflow, which is heated when passing through the heated air guide cover 106 and finally discharged from the front side of the machine head. The motor 110 is located at the rear side of the fan wheel 108, which can provide power to make the fan wheel 108 rotate.

[0062] It should be emphasized that the motor 110 in the present scheme is rear-mounted, i.e. the position of the motor 110 is set at the axial rear side of the fan wheel 108, so that in the path of air flow, after being heated by the air guide cover 106, it will be directly discharged. Compared with the scheme of front-mounted motor 110, the motor 110 itself is not affected by the hot air, which can effectively control the temperature rise. On the other hand, as Figure 3 and Figure 4 shown, since the motor 110 is arranged at the rear side, the air guide cover 106 and the fan wheel 108 are not electrified, which can be directly disassembled and washed, greatly reducing the cleaning difficulty.

[0063] It can be understood that the air outlet device 100 can mainly convert electrical energy into heat energy and mechanical energy to generate hot air. In the present scheme, by adjusting the relative position of the motor 110 and the wind wheel 108, and increasing the structure of the air guide cover 106, the air under the action of the wind wheel 108 will blow to the air guide cover 106, and the air guide cover 106 will be heated under the action of the heating device 104, which can increase the temperature of the air blown to the air guide cover 106. At the same time, through the structural characteristics of the air guide cover 106 itself, the air can be guided to the outside of the air outlet device 100, thereby providing warm air with a larger wind speed. It should be noted that although the motor is arranged at the air inlet position, the overall air volume can still meet the user's demand under the overall action of the motor, the wind wheel and the air guide cover.

[0064] It should be noted that the motor type can be a direct current or alternating current motor, or even a brushless motor to improve efficiency and reduce maintenance; the power and speed of the motor should match the design of the wind wheel; and the heat dissipation design of the motor should ensure that it will not overheat during long-time operation.

[0065] It should be noted that for the entire air outlet device, the front side is the air outlet side of the shell cover, and the rear side is the air inlet side of the shell cover, as shown by the arrow direction in FIG. Figure 2 .

[0066] Optionally, the wind wheel is selected as a centrifugal wind wheel, and the air inlet direction and the air outlet direction are not parallel, so that when the wind wheel is placed in the air guide cover, the rear side of the entire air outlet device is air-inlet, and under the action of the centrifugal wind wheel, the air is radially air-outlet to the air guide cover, and then guided by the air guide cover, and finally air-outlet to the front side of the entire air outlet device in the axial direction. That is, for the air outlet device, the air flow direction is still rear air-inlet and front air-outlet, but due to the setting of the centrifugal wind wheel, the front-to-rear dimension of the entire product is smaller, and at the same time, under the action of the centrifugal wind wheel, a higher wind speed can be maintained to improve the air supply distance.

[0067] In some embodiments, the first bearing 1122 and the second bearing 1124 are optionally arranged at intervals, and under the action of the two bearings, the shaft of the wind wheel 108 can be effectively supported and fixed to ensure the stability and balance of the wind wheel 108 during rotation, and to reduce friction and vibration caused by mechanical movement, thereby prolonging the service life of the mechanical components.

[0068] It can be understood that since the motor 110 is arranged at 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 shaking can be reduced, and the rotation stability can be improved.

[0069] It should be noted that the first bearing 1122 and the second bearing 1124 can be fixed on the shell cover, or can be fixed on a structure that is relatively fixed with the position of the shell cover.

[0070] In some embodiments, the drive shaft 1102, the first bearing 1122, the second bearing 1124, and the wind wheel 108 are coaxially arranged, thereby ensuring the precise centering 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, and its axis is a straight line, ensuring the stability and efficiency when transmitting torque. The rotation of the drive shaft 1102 directly affects the rotational speed of the wind wheel 108 and the performance of the fan. 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 efficiency and stability of the entire system.

[0071] It can be understood that the coaxial arrangement ensures the centering of the rotating components, reduces vibration and noise, and improves the life of the rotating components and the stability of the entire machine. This design is particularly important for high-speed rotating wind wheel 108 systems, as any slight deviation can lead to significant performance degradation and accelerated component wear. Through precise bearing support and centering, the system can achieve smooth and efficient operation, thereby providing continuous and stable hot air output.

[0072] Among them, 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.

[0073] The type of bearing (such as deep groove ball bearing, angular contact ball bearing, etc.) is selected according to the load requirement 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 adapt to the operating environment and temperature conditions.

[0074] In some embodiments, the air duct shell 114 is optionally arranged between the heating device 104 and the outer shell 102, and the air inlet path of the wind wheel can be provided under the action of the air duct shell 114. Specifically, the air duct is formed between the air duct shell 114 and the air guide cover 106, and the outlet of the air duct is arranged opposite to the air inlet side of the wind wheel. For the entire air conditioning device, there can be one or more inlets of the air duct, and the position of the inlet can be flexibly arranged to improve the air volume.

[0075] It can be understood that under the action of the air duct shell 114, the air can be effectively guided to the wind wheel 108 after flowing through the heating device 104 and pushed out by the wind wheel 108. The second bearing 1124 arranged on the air duct shell 114 helps to stabilize the position of the air duct shell 114, reduces vibration and friction, and ensures the stable operation of the air duct shell 114. Overall, this design of the air duct shell 114 is beneficial to improve the efficiency and stability of air flow, thereby increasing the performance and reliability of the entire system.

[0076] By limiting part of the wind wheel or all wind wheels to be arranged inside the air guide cover, the air driven by the wind wheel during rotation can be fully flowed to the air guide cover, and then be blown outwards under the guiding effect of the air guide cover after heat exchange with the air guide cover, so as to realize the blowing of hot air.

[0077] In some embodiments, the heating device can optionally include a heating bracket 1042, wherein the heating bracket 1042 is arranged corresponding to the air guide cover 106 and is arranged outside the air guide cover 106 and fixed on the air duct shell 114, which helps to ensure the effective cooperation of the heating bracket 1042 and the air guide cover 106 and provides a stable support structure. In addition, the heating bracket 1042 can be in the form of a disc, i.e., a coil disc, and by winding an electromagnetic coil on the coil disc 1044, an alternating magnetic field can be generated after the electromagnetic coil is energized, so that the air guide cover 106 realizes electromagnetic induction heating and provides an efficient way for air heating.

[0078] In some embodiments, the heat insulation bracket 1062 is fixed on the air duct shell 114 and arranged outside the air guide cover 106, and the arrangement of the heat insulation bracket 1062 can isolate the air guide cover 106 and the heating device 104 to a certain extent, reduce the conduction of heat to the air guide cover 106, and thus reduce the temperature of the air guide cover 106 and improve the safety of use. In addition, the heat insulation bracket 1062 is fixed on the air duct shell 114 to provide additional support and stability for the air guide cover 106, which helps to keep the position of the air guide cover 106 stable, reduce vibration and friction, and improve the reliability of the entire system.

[0079] By isolating and stabilizing the air guide cover 106, the working efficiency of the heating device 104 can also be improved, ensuring that the heated air can smoothly enter the air duct shell 114 and then be pushed out by the wind wheel 108.

[0080] In general, the arrangement of the heat insulation bracket 1062 in such an air outlet device 100 helps to improve the stability and safety of the system, and also helps to improve the heating efficiency and ensure the normal operation of the entire system.

[0081] In some embodiments, the heating device 104 is optionally an electromagnetic coil, the air deflector 106 is made of a magnetic conductive material, and a gap is provided between the heating device 104 and the air deflector 106. By using an electromagnetic coil as the heating device 104, electromagnetic induction heating can be achieved, which has the advantages of uniform heating, fast response, etc., and is conducive to improving the heating efficiency and controlling the heating temperature. In addition, the air deflector 106 is made of a magnetic conductive material, which helps to guide the heat field, improve the thermal efficiency, reduce energy loss, and ensure that the heated air can be effectively introduced into the air duct shell 114, thereby improving the utilization rate of hot air. It should be further pointed out that the gap provided between the heating device 104 and the air deflector 106 helps to reduce the temperature of the air deflector 106, reduce the conduction of heat to the air deflector 106, improve the safety of use, and also helps to protect the heating device 104 and prolong its service life.

[0082] In some embodiments, the housing cover 102 includes a detachably connected front mesh cover 1022 and a rear mesh cover 1024, which are connected to form a containing cavity accommodating the heating device 104, the air deflector 106, the fan wheel 108, and the motor 110, wherein the first bearing 1122 is provided on the front mesh cover 1022 for the driving shaft 1102 to pass through. The detachable connection of 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 care of the equipment.

[0083] The containing cavity formed by the connection of the front mesh cover 1022 and the rear mesh cover 1024 provides a suitable space to accommodate the heating device 104, the air deflector 106, the fan wheel 108, and the motor 110, so that these internal components can be effectively installed and fixed.

[0084] It should be further pointed out that the first bearing 1122 is provided on the front mesh cover 1022 for the driving shaft 1102 to pass through, which helps to support and fix the driving shaft 1102, ensuring the stable operation of the driving shaft 1102 and reducing vibration and friction caused by the movement of the driving shaft 1102.

[0085] In summary, the design of the housing cover 102 improves the maintenance convenience of the equipment and the installation stability of the internal components, which is conducive to the use and maintenance of the entire system.

[0086] It should be noted that the structure of the entire housing cover 102 is a fully enclosed structure in the middle, forming a ring-shaped shell, and a grille is provided in front and back, wherein at least one of the front mesh cover 1022 and the rear mesh cover 1024 is designed with a middle shell, i.e., the middle shell can be part of the front mesh cover 1022 or the rear mesh cover 1024.

[0087] In the assembly, the air deflector 106 and the air wheel 108 can be assembled together to form a modular structure, which can be removed as a whole from the air conditioning device 100. Since the modular structure does not have any electronic components, it can be directly cleaned with water, improving the convenience and safety of cleaning.

[0088] It can be understood that the modular structure is detachable from the heating device 104 and the motor 110.

[0089] In some embodiments, the electric heating wire is optionally used as the heating device 104, which can quickly generate heat. The air deflector 106 made of heat-conducting material helps to quickly conduct the heat, improves the heating efficiency, and makes the heated air be sent to the air duct shell 114 more quickly.

[0090] The air deflector 106 is made of heat-conducting material, and the heating device 104 is arranged on the air deflector 106. The air deflector 106 made of heat-conducting material helps to quickly conduct and discharge the heated air, thereby improving the utilization rate of the hot air and ensuring the stable output of the hot air. By arranging the heating device 104 on the air deflector 106, the heat conduction of the heating device 104 to other components is reduced, the temperature of the device is lowered, and the safety of use is improved.

[0091] Another embodiment of the warm air blower 200 is provided in the present application, as shown in Figure 5 The air deflector 106 and the air wheel 108 can be assembled together to form a modular structure, which can be removed as a whole from the air conditioning device 100. Since the modular structure does not have any electronic components, it can be directly cleaned with water, improving the convenience and safety of cleaning.

[0092] In addition, since the base support 202 is detachably connected with the air deflector 106, different air deflector 106 can be selected according to the needs, so that the warm air blower 200 has wider applicability and flexibility.

[0093] In one specific embodiment, an IH side wall heating hair dryer 200 structure is proposed, the whole machine structure, including motor 110, front mesh cover 1022, fan wheel 108, shell (ie shell cover 102), heating fin (ie air deflector 106), heating fin support (ie heat shield support 1062), coil disc support (ie heating support 1042), air duct (ie air duct shell 114) and other structures. The overall scheme adopts a centrifugal fan (ie fan wheel 108 + motor 110) as a power pack, which has the characteristics of axial air inlet and radial air outlet. The outlet airflow is thrown out under the action of centrifugal force. The side wall of the power pack is made of a magnetically conductive metal part, which is heated by electromagnetic induction. When working, the airflow is heated by the heated side wall, thereby realizing the hair dryer function.

[0094] The whole machine structure is arranged as follows. First, the heating fin must be made of a metal that can conduct magnetism (conventional, including 430 stainless steel, iron, etc.). The heating fin will heat up under the action of electromagnetic induction when working. The heating fin is fixed on the heating fin support, which is usually made of a high-temperature resistant plastic part (nylon + glass fiber material). The heating fin support usually plays two roles: first, it fixes the heating fin, and second, it insulates heat. Since the heating fin can reach more than 200 degrees Celsius when working, conventional electronic devices cannot withstand such temperatures, so the plastic support needs to be wrapped on the outside to play a certain heat insulation role. There is a coil disc support outside the heating fin support. The coil disc has an electromagnetic coil wound around it. After being powered on, it generates an alternating magnetic field, thereby heating the heating fin. The heating fin support and the coil disc support are fixed together on the air duct shell.

[0095] The air duct shell mainly plays two roles: first, it forms a heat dissipation air duct, and second, it serves as a fastening support structure. The fixation of other structural components is relatively conventional. The fan wheel is fixed on the motor, the motor is fixed on the shell, and finally the front mesh cover is fixed on the shell to form a complete machine.

[0096] The whole machine structure can place the motor at the air outlet position or the air inlet position during the design process. Generally, considering the air inlet (axial air inlet) of the centrifugal fan, placing the motor at the air inlet end will cause larger air duct resistance. Therefore, the conventional scheme is to place the motor at the air outlet end. However, considering the following two points, the motor is placed at the air inlet end in the scheme. First, after placing the motor at the air inlet end, all electrical devices are behind the whole machine, and the power pack system of the warm air blower can be powered off and completely disassembled for cleaning. Second, when the motor is placed at the air outlet end, the high-temperature hot air flow will pass through the motor before being blown out, causing the motor to have excessively high temperature rise. However, the problems caused by placing the motor at the air inlet end also need to be solved. First, in order to make the air inlet resistance as small as possible, the motor should be away from the fan wheel, and such a design causes the motor shaft to be very long. During the manufacturing process of the fan wheel, there will be certain dynamic imbalance, and the excessively long motor shaft will amplify the defects on the fan wheel and cause large vibration. In order to solve such a problem, two levels of fixation are added to the structural member. The motor shaft is limited by the front mesh cover and the air duct shell through two bearings, so as to limit the vibration of the fan wheel and the motor.

[0097] According to the air outlet equipment and the warm air blower provided by the utility model, the motor itself can be guaranteed not to be affected by hot air in the case of large air volume air outlet, the temperature rise can be effectively controlled, on the other hand, since the motor is arranged at the rear side, the air guide cover and the fan wheel are not electrified, and can be directly disassembled and washed during cleaning, so that the cleaning difficulty is greatly reduced.
