Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] The following is for reference. Figures 1-12 This invention describes an air handling device 100 according to an embodiment of the present invention.

[0052] Combination Figures 1 to 3 According to an embodiment of the present invention, an air handling device 100 includes a housing 110 and a fan 120. The housing 110 is provided with an air inlet 111 and an air outlet 112. The fan 120 is disposed inside the housing 110. Air can enter the housing 110 through the air inlet 111. The fan 120 can drive the air entering the housing 110 to flow from the air inlet 111 to the air outlet 112, thereby improving the air flow efficiency inside the housing 110.

[0053] Combination Figures 1 to 4 The air handling unit 100 also includes an electronic control component 130, which is located inside the housing 110. By placing the electronic control component 130 inside the housing 110, it is beneficial to improve the space utilization rate inside the housing 110 and facilitate the miniaturization design of the air handling unit 100.

[0054] Furthermore, the impeller 120 is provided with a clearance space 121, and at least a portion of the electronic control component 130 is located within the clearance space 121. This helps to reduce the space required to arrange the electronic control component 130 within the housing 110, and also enables the integration of the electronic control component 130 with the impeller 120, making the structure of the electronic control component 130 and the impeller 120 compact. This helps to reduce the volume of the air handling equipment 100, facilitates the miniaturization design of the air handling equipment 100, and further helps to reduce the space required to arrange the air handling equipment 100.

[0055] Optionally, the entire electrical control component 130 can be installed within the clearance space 121, or the portion of the electrical control component 130 closest to the wind turbine 120 can be installed within the clearance space 121. The specific portion of the electrical control component 130 located within the clearance space 121 can be determined according to actual production requirements and is not specifically limited here.

[0056] In related technologies, the electrical control components of air handling equipment occupy a large space, which increases the overall size of the air handling equipment and thus requires a large space for installation, making it inconvenient for the air handling equipment to be installed.

[0057] This application integrates the electronic control component 130 with the wind turbine 120 by providing a clearance space 121 on the wind turbine 120 and placing at least a portion of the electronic control component 130 within the clearance space 121. This improves the structural compactness of the electronic control component 130 and the wind turbine 120, and reduces the space required to arrange the electronic control component 130 within the housing 110. This helps to reduce the volume of the air handling equipment 100, thereby facilitating the miniaturization design of the air handling equipment 100, further reducing the space required to arrange the air handling equipment 100, and improving the ease of installation of the air handling equipment 100.

[0058] Combination Figures 3 to 6 In some embodiments of this utility model, the portion of the electronic control component 130 located within the clearance space 121 is spaced apart from the inner wall of the clearance space 121.

[0059] Since the clearance space 121 is located on the wind turbine 120, and the inner wall of the clearance space 121 is part of the wind turbine 120, in order to prevent the electronic control component 130 from interfering with the operation of the wind turbine 120 due to contact with the inner wall of the clearance space 121, it is necessary to set the portion of the electronic control component 130 located in the clearance space 121 at a distance from the inner wall of the clearance space 121. This reduces the risk of the electronic control component 130 interfering with the operation of the wind turbine 120, improves the smoothness of the operation of the wind turbine 120, and thus helps to ensure the efficiency of the wind turbine 120 in driving airflow.

[0060] Combination Figures 3 to 6In some embodiments of this utility model, on the axial direction of the wind turbine 120, the distance between any side of the portion of the electronic control component 130 located in the clearance space 121 and the clearance space 121 is a first distance S1, which is greater than 8mm.

[0061] Considering that the electronic control component 130 is prone to move in the axial direction of the impeller 120 when the air handling equipment 100 shakes, the first gap S1 is made greater than 8mm to reserve sufficient movement space for the electronic control component 130 in the axial direction of the impeller 120. This helps to further reduce the risk of the electronic control component 130 contacting the inner wall of the clearance space 121, thereby further reducing the risk of the electronic control component 130 interfering with the operation of the impeller 120 and improving the smoothness of the impeller 120's operation.

[0062] Combination Figures 3 to 6 In the radial direction of the wind turbine 120, the distance between the portion of the electronic control component 130 located in the clearance space 121 and the clearance space 121 is the second distance S2, which is greater than 8mm.

[0063] Considering that the electronic control component 130 may move in the radial direction of the impeller 120 when the air handling equipment 100 shakes, by making the second gap S2 greater than 8mm, sufficient movement space is reserved for the electronic control component 130 in the radial direction of the impeller 120. This helps to further reduce the risk of the electronic control component 130 contacting the inner wall of the clearance space 121, thereby further reducing the risk of the electronic control component 130 interfering with the operation of the impeller 120 and improving the smoothness of the operation of the impeller 120.

[0064] Optionally, the spacing between the electronic control component 130 and the clearance space 121 can satisfy either the first spacing S1 being greater than 8mm, or the second spacing S2 being greater than 8mm, or both the first spacing S1 being greater than 8mm and the second spacing S2 being greater than 8mm. It is understood that the spacing between the electronic control component 130 and the clearance space 121 can be determined according to actual production requirements and is not specifically limited here.

[0065] Combination Figures 3 to 6 In some embodiments of the present invention, the electronic control assembly 130 includes a circuit board 131 and an electronic control element 132 disposed on the circuit board 131, with at least a portion of the circuit board 131 located in the clearance space 121.

[0066] The circuit board 131 serves as the mounting carrier for the electronic control component 132. The electronic control component 132 is arranged on the circuit board 131 and electrically connected to the circuit board 131. By placing at least a portion of the circuit board 131 in the clearance space 121, the structural compactness of the electronic control component 130 and the impeller 120 is improved, which helps to reduce the space occupied by the circuit board 131 in the housing 110 and facilitates the miniaturization design of the air handling equipment 100.

[0067] Optionally, when there is sufficient space on the impeller 120 to accommodate the clearance space 121, that is, when the size of the clearance space 121 is sufficient, the entire circuit board 131 can be placed within the clearance space 121. When the size of the clearance space 121 is insufficient to accommodate the entire circuit board 131, the portion of the circuit board 131 closest to the impeller 120 can be placed within the clearance space 121. The specific portion of the circuit board 131 located within the clearance space 121 can be determined according to actual production requirements and is not specifically limited here.

[0068] It should be noted that the electronic control component 132 may include power devices (IGBTs and bridge rectifiers), capacitors, inductors, resistors, and transformers, etc. In addition, the circuit board 131 is also provided with a signal socket and a power input interface. The signal socket is used to connect external devices (such as sensors, controllers, or other electronic devices) to facilitate data exchange and communication. The power input interface is used to connect to the power supply system of the circuit board 131 to provide the power required for the circuit board 131 to operate, ensuring that the components on the circuit board 131 can operate normally.

[0069] Combination Figure 4 , Figure 7 and Figure 8 In some embodiments of this utility model, the thickness direction of the circuit board 131 is parallel to the axial direction of the impeller 120. That is, the electronic control component 130 can be vertically inserted into the clearance space 121 in a direction perpendicular to the rotation axis of the impeller 120. This helps to reduce the size of the clearance space 121 in the axial direction of the impeller 120, thereby reducing the space occupied by the clearance space 121 in the axial direction of the impeller 120, and further reducing the impact of setting the clearance space 121 on the air output efficiency of the impeller 120.

[0070] Combination Figure 4 , Figure 7 and Figure 8 The surface of the circuit board 131 located within the clearance space 121 and facing the impeller 120 is formed as an arc surface that matches the impeller 120.

[0071] For example, the clearance space 121 is provided on the outer peripheral wall of the impeller 120, and the clearance space 121 extends along the circumferential direction of the impeller 120. In the radial direction of the impeller 120, the surface of the circuit board 131 opposite to the impeller 120 is formed into an arc surface with the same shape as the outer peripheral wall of the impeller 120, so as to facilitate the arrangement of the circuit board 131 in the clearance space 121, which is beneficial to improving the effect of saving the space required to arrange the circuit board 131.

[0072] It should be noted that "the outer peripheral wall of the impeller 120" refers to the side wall of the impeller 120 opposite to the housing 110 in the radial direction of the impeller 120.

[0073] Combination Figure 4 , Figure 5 , Figure 7 and Figure 8 In the radial direction of the impeller 120, the surface of the circuit board 131 away from the impeller 120 matches the shape of the inner peripheral wall of the housing 110.

[0074] It should be noted that "the inner peripheral wall of the housing 110" refers to the side wall of the housing 110 opposite to the wind turbine 120 in the radial direction of the wind turbine 120.

[0075] For example, the housing 110 can be formed in a cylindrical shape, and correspondingly, the inner peripheral wall of the housing 110 is an arc-shaped wall. In the radial direction of the impeller 120, the surface of the circuit board 131 opposite to the housing 110 is formed in an arc shape with the same shape as the inner peripheral wall of the housing 110, so as to achieve the shape matching between the surface of the circuit board 131 away from the impeller 120 and the inner peripheral wall of the housing 110. This is beneficial to increase the area of ​​the circuit board 131 while improving the effect of saving the space required to arrange the circuit board 131.

[0076] Combination Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments of this utility model, the circuit board 131 is formed as an annular plate or a fan-shaped annular plate in the circumferential direction of the impeller 120.

[0077] For example, the circuit board 131 can be constructed as a fan-shaped annular plate to reduce the space required to arrange the circuit board 131. In the radial direction of the impeller 120, the surface of the circuit board 131 opposite to the impeller 120 is formed as an arc surface that matches the impeller 120. The surface of the circuit board 131 opposite to the housing 110 matches the inner peripheral wall of the housing 110, so as to increase the area of ​​the circuit board 131, ensuring that the circuit board 131 can provide sufficient installation space for the electronic control component 132, while saving the space required to arrange the circuit board 131, thereby facilitating the miniaturization design of the air handling equipment 100.

[0078] Furthermore, in the radial direction of the impeller 120, the radius of the side of the circuit board 131 closest to the impeller 120 (which can also be understood as the inner diameter of the circuit board 131) is defined as R1, and the size range of R1 is 60mm to 90mm. The radius of the side of the circuit board 131 furthest from the impeller 120 (which can also be understood as the outer diameter of the circuit board 131) is defined as R2, and the size range of R2 is 110mm to 140mm, so as to ensure that the size of the circuit board 131 can meet the installation requirements of the electronic control component 132.

[0079] The radius Rb of the impeller 120 is typically between 70mm and 150mm. Since R1 < Rb, a clearance space 121 is provided on the impeller 120 so that the impeller 120 can avoid the electronic control component 130. This facilitates the integration of the electronic control component 130 with the impeller 120, improves the structural compactness of the electronic control component 130 and the impeller 120, and helps to reduce the space occupied by the electronic control component 130 in the housing 110, thereby facilitating the miniaturization design of the air handling equipment 100.

[0080] In other embodiments, the circuit board 131 may be formed as an annular plate surrounding the impeller 120 in the circumferential direction of the impeller 120, so as to increase the area of ​​the circuit board 131 and ensure that the circuit board 131 can provide sufficient installation space for the electronic control component 132.

[0081] By constructing the circuit board 131 as a ring-shaped plate or a fan-shaped plate, the circuit board 131 can be matched with the clearance space 121 provided on the impeller 120, so that at least a part of the circuit board 131 can be arranged in the clearance space 121, while reducing the space occupied by the circuit board 131.

[0082] like Figure 10 As shown, in some embodiments of this utility model, at least some of the electronic control components 132 are located on the side of the circuit board 131 facing the air inlet 111.

[0083] When the electronic control assembly 130 is working, the electronic control element 132 will generate heat. By positioning the electronic control element 132 on the side of the circuit board 131 facing the air inlet 111, the low-temperature external air entering the housing 110 through the air inlet 111 can preferentially flow through the electronic control element 132 and dissipate heat from it. This is beneficial to improve the heat dissipation efficiency of the electronic control element 132, reduce the risk of overheating of the electronic control element 132, and improve the service life of the air handling equipment 100.

[0084] Optionally, all electronic control components 132 can be arranged on the side of the circuit board 131 facing the air inlet 111, or some electronic control components 132 can be arranged on the side of the circuit board 131 facing the air inlet 111. The specific arrangement of the electronic control components 132 can be determined according to actual production requirements, and no specific limitation is made here.

[0085] Combination Figures 7 to 9 In some embodiments of this utility model, in the radial direction of the impeller 120, the end of the electronic control component 130 away from the impeller 120 is fixed to the housing 110.

[0086] For example, in the radial direction of the impeller 120, a mounting part 133 is provided on the side of the circuit board 131 away from the impeller 120. A mounting mating part 113 can be provided at the position opposite to the mounting part 133 of the housing 110. The mounting part 133 and the mounting mating part 113 can be formed as threaded holes. The circuit board 131 can be fixed to the housing 110 by threaded fasteners (such as screws) to realize the positioning and installation of the electronic control component 130 and the housing 110, and facilitate the disassembly and assembly of the electronic control component 130. This improves the convenience of maintenance or replacement of the electronic control component 130, thereby helping to reduce the maintenance cost of the air handling equipment 100.

[0087] By fixing the end of the electronic control component 130 away from the wind turbine 120 in the radial direction to the housing 110, it is beneficial to improve the assembly reliability of the electronic control component 130, and it is also convenient to arrange the end of the electronic control component 130 close to the wind turbine 120 in the clearance space 121, which is beneficial to improve the assembly convenience of the electronic control component 130.

[0088] Combination Figure 3 and Figure 6 In some embodiments of this utility model, the impeller 120 is a centrifugal impeller, the clearance space 121 is located on the outer peripheral wall of the impeller 120, and the electrical control component 130 is located at the air outlet end of the centrifugal impeller.

[0089] The centrifugal impeller has an axial air intake and a radial air outlet. The clearance space 121 is set on the outer peripheral wall of the impeller 120 and is recessed inward along the radial direction of the impeller 120. That is, the clearance space 121 is located at the air outlet end of the impeller 120. At least part of the electrical control component 130 is located in the clearance space 121, so that the electrical control component 130 is arranged on the radial side of the impeller 120 and located at the air outlet end of the centrifugal impeller. By setting the electrical control component 130 at the air outlet end of the centrifugal impeller, it is convenient for the air flowing out of the impeller 120 to flow through the electrical control component 130, thereby facilitating the heat dissipation of the electrical control component 130 and facilitating the assembly of the electrical control component 130, which is beneficial to improving the production and assembly efficiency of the air handling equipment 100.

[0090] Combination Figure 3 , Figure 4 and Figure 6 In some embodiments of the present invention, in the radial direction of the wind turbine 120, the radially outer ends of some blades of the wind turbine 120 are recessed toward the rotation axis of the wind turbine 120 to define a clearance space 121.

[0091] Specifically, the impeller 120 is formed as a centrifugal impeller, and the clearance space 121 is set at the air outlet end of the impeller 120. That is, at least a part of the clearance space 121 is located in the air outlet area of ​​the blade. In the radial direction of the impeller 120, the radial dimension of the part of the blade that is directly opposite to the clearance space 121 is smaller than the radial dimension of the part of the blade that is not directly opposite to the clearance space 121 in the axial direction. Thus, by designing the blades of the impeller 120, a clearance space 121 that is recessed in the radial direction of the impeller 120 can be formed on the impeller 120, which facilitates the arrangement of the electronic control component 130 in the clearance space 121, realizing the integration of the electronic control component 130 with the impeller 120, and facilitating the dissipation of heat from the air discharged by the impeller 120 on the electronic control component 130.

[0092] Combination Figures 1 to 3 In some embodiments of the present invention, the air handling device 100 further includes a heating element 140, which is configured to heat the air to achieve the heating function of the air handling device 100. A portion of the impeller 120 is located inside the heating element 140, and the clearance space 121 is located outside the heating element 140.

[0093] For example, in the axial direction of the impeller 120, a portion of the impeller 120 extends into the heating element 140, and another portion of the impeller 120 extends out of the heating element 140. In the radial direction of the impeller 120, the impeller 120 and the heating element 140 can be spaced apart to prevent the heating element 140 from interfering with the operation of the impeller 120 and to ensure the smooth operation of the impeller 120. At the same time, since a portion of the impeller 120 is located inside the heating element 140, it is beneficial to improve the guiding effect of the impeller 120 on the air inside the heating element 140, thereby improving the heat exchange efficiency between the air and the heating element 140.

[0094] The clearance space 121 is provided on a portion of the impeller 120 located outside the heating element 140, so as to facilitate the placement of at least a portion of the electronic control component 130 within the clearance space 121. In other words, it facilitates the placement of the electronic control component 130 outside the heating element 140, which helps to prevent the electronic control component 130 from being unable to be installed due to insufficient space inside the heating element 140. At the same time, it allows the electronic control component 130 to be placed away from the heating element 140, reducing the impact of the heat generated by the heating element 140 on the electronic control component 130, thereby reducing the risk of overheating of the electronic control component 130.

[0095] Optionally, the heating element 140 can be configured as a component that generates heat when it is powered on. For example, the heating element 140 can be configured as a PTC heating element, or the heating element can be configured as a component that generates heat through contact or non-contact means. For example, the heating element 140 can be configured to generate heat under the action of a magnetic field. Of course, it is understood that the specific construction of the heating element 140 can be determined according to the actual production requirements, and no specific limitation is made here.

[0096] Combination Figures 1 to 3 In some embodiments of this utility model, in the axial direction of the impeller 120, the clearance space 121 is located on the side of the heating element 140 near the air inlet 111.

[0097] Specifically, along the axial direction of the impeller 120, a portion of the impeller 120 is disposed within the heating element 140, and the impeller 120 extends from within the heating element 140 toward the air inlet 111. A clearance space 121 is disposed on the portion of the impeller 140 located outside the heating element 140 and near the air inlet 111, such that the clearance space 121 is positioned closer to the air inlet 111 than the heating element 140. This allows the electronic control component 130 to be positioned closer to the air inlet 111 than the heating element 140, which helps to reduce the impact of the heat generated by the heating element 140 on the electronic control component 130. At the same time, it allows the air entering the housing 110 from the air inlet 111 to preferentially dissipate heat from the electronic control component 130, thereby improving the heat dissipation efficiency of the electronic control component 130.

[0098] Combination Figures 1 to 3 In some embodiments of this utility model, the heating element 140 is formed as a closed ring or as a ring with an opening in the circumferential direction, and a portion of the impeller 120 is located inside the heating element 140.

[0099] For example, the heating element 140 can be formed as a closed ring in its circumferential direction. A portion of the impeller 120 away from the air inlet 111 extends into the heating element 140, and the air discharged from the portion of the impeller 120 extending into the heating element 140 can flow within the space defined by the heating element 140 to dissipate heat from the heating element 140. The heating element 140 can also limit the diffusion of air in its radial direction, which is beneficial to improving the efficiency of air flowing to the air outlet 112.

[0100] Alternatively, the heating element 140 can be formed as an annular ring with an opening in its circumferential direction, that is, the heating element 140 is not closed in its circumferential direction, so that the heating element 140 can cooperate with a part of the fan wheel 120 extending therein, ensuring the heat dissipation effect of the air on the heating element 140 while reducing the material cost of the heating element 140, thereby helping to reduce the production cost of the air handling equipment 100.

[0101] Combination Figures 1 to 3 In some embodiments of the present invention, the air handling device 100 further includes an electromagnetic coil for generating a magnetic field. The electromagnetic coil is located on the side of the heating element 140 away from the impeller 120 in the radial direction of the impeller 120. The heating element 140 is configured to generate heat under the action of the magnetic field of the electromagnetic coil.

[0102] In other words, the electromagnetic coil is located radially outside the heating element 140 in the radial direction of the impeller 120. Through the cooperation between the electromagnetic coil and the heating element 140, electromagnetic induction heating can be achieved. The electromagnetic induction heating method has the advantages of uniform heating and rapid response, which is beneficial to improving the heating efficiency of the air handling equipment 100.

[0103] By arranging the electronic control component 130 inside the housing 110, the wiring harness used to electrically connect the electronic control component 130 to the electromagnetic coil can be arranged inside the housing 110. When the air handling equipment 100 rotates, the wiring harness, the electronic control component 130, and the housing 110 can rotate synchronously, thereby reducing the risk of the wiring harness cutting the magnetic field due to its movement relative to the electromagnetic coil, which helps to reduce the risk of excessive heat generation of the electromagnetic coil.

[0104] Combination Figure 11 and Figure 12 In some embodiments of this utility model, in the axial direction of the impeller 120, the diameter of the portion of the impeller 120 located outside the heating element 140 is D, and the diameter of the portion of the impeller 120 located inside the heating element 140 is d, where 0.5≤d / D≤0.9.

[0105] Considering that both the electromagnetic coil and the heating element 140 need to dissipate heat, the diameter D of the portion of the impeller 120 located outside the heating element 140 is made larger than the diameter d of the portion of the impeller 120 located inside the heating element 140. This allows the airflow driven by the portion of the impeller 120 located outside the heating element 140 to flow through the electromagnetic coil, thereby improving the heat dissipation effect of the impeller 120 on the electromagnetic coil, preventing the electromagnetic coil from overheating, and ensuring the heat dissipation effect of the impeller 120 on the heating element 140.

[0106] When d / D < 0.5, it easily leads to poor heat dissipation effect of the impeller 120 on the heat source 140, or the diameter of the part of the impeller 120 located outside the heat source 140 is too large, thus increasing the size of the air handling equipment 100. When d / D > 0.9, it easily leads to poor heat dissipation effect of the impeller 120 on the electromagnetic coil, or the diameter of the part of the impeller 120 located inside the heat source 140 is too large, thus the gap between the impeller 120 and the heat source 140 is too small, affecting the air outlet effect of the impeller 120.

[0107] Combination Figure 11 and Figure 12 In some embodiments of this utility model, the axial dimension of the impeller 120 is defined as L, and the axial dimension of the portion of the impeller 120 located within the heating element 140 is defined as s, where 0.4≤s / L≤0.8. This is beneficial for matching the axial dimension of the portion of the impeller 120 located within the heating element 140 with the axial dimension of the heating element 130, and also helps to ensure the heat dissipation effect of the impeller 120 on the heating element 140 and the electromagnetic coil.

[0108] Combination Figures 1 to 3 In some embodiments of this utility model, the air handling device 100 further includes a coil support 151, an electromagnetic coil is fixed to the coil support 151, and the coil support 151 is formed into a ring and sleeved onto the heating element 140.

[0109] The coil support 151 is correspondingly arranged with the heating element 140 and is located outside the heating element 140 in the radial direction of the impeller 120. This helps to ensure the effective cooperation between the electromagnetic coil and the heating element 140. Furthermore, the coil support 151 can provide stable support for the electromagnetic coil, which helps to improve the assembly stability of the electromagnetic coil.

[0110] Combination Figures 1 to 3 In some specific embodiments, the coil support 151 is formed as a cylinder, the coil support 151 is sleeved on the heating element 140, and a plurality of winding protrusions 152 are provided on the outer peripheral wall of the coil support 151. The plurality of winding protrusions 152 are arranged at intervals in the axial direction of the impeller 120, and a winding groove is formed between two adjacent winding protrusions 152. The electromagnetic coil can be set on the coil support 151 through the plurality of winding grooves to improve the assembly stability of the electromagnetic coil.

[0111] Combination Figures 1 to 3 In some embodiments of this utility model, the air handling device 100 further includes a shield 160, which is located on the side of the electromagnetic coil away from the heating element 140, and the shield 160 is made of magnetic material.

[0112] Considering that after the electromagnetic coil is energized, a magnetic field will also be generated on the side of the electromagnetic coil away from the heating element 140 in the radial direction of the impeller 120, causing magnetic field leakage, a shield 160 is provided on the side of the electromagnetic coil away from the heating element 140 to reduce the amount of magnetic field leakage on the side of the electromagnetic coil away from the heating element 140. This also helps to increase the magnetic field strength on the side of the electromagnetic coil close to the heating element 140, thereby improving the heating effect of the heating element 140 and thus improving the heating efficiency of the air handling equipment 100.

[0113] It should be noted that the magnetic materials can be neodymium iron boron permanent magnets, ferrite permanent magnets, silicon steel, metal soft magnetic powder cores, and ferrite soft magnets, etc.

[0114] In some embodiments of this utility model, the shielding member 160 includes a plurality of permanent magnets arranged at circumferential intervals along the electromagnetic coil.

[0115] By arranging multiple permanent magnets at intervals along the circumferential direction of the electromagnetic coil, the shielding component 160 improves the effect of shielding the electromagnetic coil away from the heating element 140 from magnetic field leakage. Furthermore, the permanent magnets have high stability and can maintain their magnetism for a long time, which helps to extend the service life of the shielding component 160.

[0116] Combination Figures 1 to 3 In some embodiments of this utility model, the air handling equipment 100 further includes a shielding bracket 162. The shielding bracket 162 is formed in a ring shape and is sleeved on the radial outer side of the electromagnetic coil in the radial direction of the impeller 120. The shielding bracket 162 is used to install the shielding component 160. By setting the shielding bracket 162, the assembly of the shielding component 160 is facilitated, and the assembly reliability of the shielding component 160 is improved.

[0117] Combination Figures 1 to 3 In some embodiments of this utility model, the air handling device 100 further includes a first driving device 170. The first driving device 170 can be disposed in the housing 110 and connected to the impeller 120. When the first driving device 170 is running, it can drive the impeller 120 to rotate, and the impeller 120 can drive the airflow.

[0118] Combination Figures 1 to 3 In some embodiments of this utility model, the housing 110 includes a housing body 114, on which an air inlet 111 and an air outlet 112 are formed respectively. The heating element 140, the electronic control component 130, the impeller 120, and the first drive device 170 can all be arranged inside the housing body 114. The housing body 114 can provide positioning support for the heating element 140, the electronic control component 130, the impeller 120, and the first drive device 170, which is beneficial to improving the structural stability of the air handling equipment 100. Furthermore, the housing body 114 can protect the above-mentioned structures, which is beneficial to reducing the risk of damage to the first drive device 170 and other structures, thereby improving the service life of the air handling equipment 100.

[0119] Combination Figures 1 to 3 In some embodiments of this utility model, an air inlet screen 115 is provided at the air inlet 111 of the shell body 114. The air inlet screen 115 is detachably mounted on the shell body 114 so that the user can remove the air inlet screen 115 for cleaning, and at the same time facilitate the cleaning and maintenance of the structure inside the shell body 114.

[0120] In some embodiments, when the air handling unit 100 is actually in use, the air inlet 111 is located on the rear side of the housing 110 and the air outlet 112 is located on the front side of the housing 110. That is, the air handling unit 100 takes in air from the rear side and outputs airflow forward.

[0121] The assembly method of the air handling equipment 100 will be briefly described below based on the structure of the air handling equipment 100 according to an embodiment of the present invention.

[0122] Assembly Method 1: The heating element 140 is fixedly connected to the coil support 151 with an electromagnetic coil. The shielding component is fixedly installed on the shielding support 162. The shielding support 162 is sleeved on the radial outer side of the coil support 151 and fixedly connected to the coil support 151. The impeller 120 can be positioned in the center area of ​​the heating element 140 by hand. The electronic control component 130 is arranged in the clearance space 121 and fixedly connected to the shielding support 150. This realizes the modular assembly of the heating element 140, the coil support 151, the electronic control component 130, the shielding component, the shielding support 162, and the impeller 120. Then, the above components are placed into the shell body 114, and the coil support 151 is further fixedly connected to the shell body 114, so that the impeller 120 is connected to the shell body 114. Finally, the air inlet mesh cover 115 is installed at the air inlet 111 of the shell body 114 to complete the assembly of the air handling equipment 100.

[0123] In order to ensure the assembly reliability of the components inside the shell body 114 with the shell body 114, the shielding bracket 162 can be further connected to the shell body 114 to reduce the risk of the components inside the shell body 114 falling off the shell body 114.

[0124] Assembly Method 2: First, the heating element 140 is fixedly installed inside the shell body 114. Then, the coil bracket 151 with an electromagnetic coil is fitted onto the radial outer side of the heating element 140, and the coil bracket 151 is fixedly connected to the shell body 114. Next, the shielding bracket 162 with a shielding component is fitted onto the radial outer side of the coil bracket 151, and the shielding bracket 162 is fixedly connected to the shell body 114. Then, the impeller 120 is positioned in the central area of ​​the heating element 140 and connected to the shell body 114. The electrical control component 130 can be installed on the shielding bracket 162 or the shell body 114. Finally, the air inlet mesh cover 115 is installed at the air inlet 111 of the shell body 114 to complete the assembly of the air handling equipment 100.

[0125] Optionally, the above-mentioned fixed connection method can be to fix the components together by means of threaded connectors, so as to facilitate the disassembly, maintenance and cleaning of the air handling equipment 100. Of course, it is understood that the fixed connection method includes, but is not limited to, connecting by threaded connectors, or by means of snap-fit, etc. The specific fixed connection method can be determined according to the actual production requirements, and no specific limitation is made here.

[0126] Reference Figure 13 The heater 200 according to the present utility model includes the air handling equipment 100 described above.

[0127] Since the heater 200 is equipped with the aforementioned air handling unit 100, by providing a clearance space 121 on the impeller 120 and ensuring that at least a portion of the electronic control component 130 is located within the clearance space 121, the electronic control component 130 and the impeller 120 are integrated, improving the structural compactness of the electronic control component 130 and the impeller 120. This also reduces the space required to arrange the electronic control component 130 within the housing 110, which helps to reduce the volume of the air handling unit 100. This facilitates the miniaturization design of the air handling unit 100, further reducing the space required to arrange the air handling unit 100 and improving the ease of installation of the air handling unit 100.

[0128] Reference Figure 13 In some embodiments of this utility model, the heater 200 also includes a bracket 210, and the air handling unit 100 is rotatably mounted on the bracket 210 to adjust the air outlet direction.

[0129] For example, the heater 200 also includes a base 220, a bracket 210 rotatably connected to the base 220, and a second driving device is provided on the base 220. The second driving device can drive the bracket 210 to rotate in the left and right direction relative to the base 220. The bracket 210 can form an installation space. The inner wall of the installation space is provided with a connecting part. The air handling equipment 100 is rotatably connected to the connecting part and accommodated in the installation space. For example, the connecting part of the bracket 210 clamps the air handling equipment 100 in the left and right direction and drives the air handling equipment 100 to rotate up and down.

[0130] Optionally, the vertical rotation of the air handling unit 100 can also be in the form of a guide rail. Alternatively, the bracket 210 can be mounted on the base 220, and the second drive device can be mounted on the bracket 210 and connected to the air handling unit 100 for transmission, so as to drive the air handling unit 100 to rotate vertically or horizontally.

[0131] The second drive unit can be configured as a drive motor.

[0132] In some embodiments of this utility model, the heater 200 has a cold air operation mode and a warm air operation mode, so that the heater 200 can provide suitable air output according to the user's needs, which is beneficial to improving the functionality of the heater 200.

[0133] When the heater 200 is in cold air operation mode, the fan wheel 120 starts, and the heating element 140 does not work, so as to ensure that the heater 200 can provide clean cold air, so that the heater 200 can cool down the high temperature environment, and at the same time, it helps to reduce the energy consumption of the heater 200.

[0134] When the heater 200 is in the warm air operation mode, the fan wheel 120 and the heating element 140 work simultaneously to ensure that the heater 200 can output hot air, so that the heater 200 can be used to heat the environment with low temperature.

[0135] In some embodiments, the cold air operation mode of the heater 200 needs to ensure that the output air speed of the heater 200 is high enough. That is, the number of speed settings in the cold air operation mode of the heater 200 is greater than the number of speed settings in the warm air operation mode, and the maximum air speed in the cold air operation mode is greater than the maximum air speed in the warm air operation mode. For example, the heater 200 can have 8 speed settings in the cold air operation mode and 3 speed settings in the warm air operation mode. When the heater 200 switches directly from the 3rd speed setting in the cold air operation mode to the warm air mode, the heater 200 operates at the maximum speed setting (i.e., the third speed setting) in the warm air mode, and the heater 200 outputs the hot air most efficiently.
