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

[0058] The following is for reference. Figures 1-10 This invention describes an air handling device 100 according to an embodiment of the present invention.

[0059] 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 140. The housing 110 is provided with an air inlet 111 and an air outlet 112. Air can enter the housing 110 through the air inlet 111. The fan 140 is disposed inside the housing 110. After the air enters the housing 110 through the air inlet 111, the fan 140 can drive the air entering the housing 110 to flow from the air inlet 111 to the air outlet 112, so as to improve the air flow efficiency inside the housing 110.

[0060] Combination Figures 1 to 3 The air handling equipment 100 also includes a coil module 120 and a heating element 130. The coil module 120 is disposed inside the housing 110 and includes an electromagnetic coil capable of generating a magnetic field. The heating element 130 is disposed inside the housing 110 and is configured to generate heat under the action of the magnetic field of the electromagnetic coil.

[0061] Electromagnetic induction heating can be achieved through the cooperation of electromagnetic coil and heating element 130. Electromagnetic induction heating has the advantages of uniform heating and rapid response, which helps to improve the heating efficiency of heating element 130. Since heating element 130 is set inside housing 110, heating element 130 can heat the air entering housing 110 so that air handling equipment 100 can output hot air.

[0062] In the axial direction of the impeller 140, the first part 141 of the impeller 140 is located inside the heating element 130 so that the first part 141 can send air to the inner wall of the heating element 130, thereby facilitating the heat dissipation of the heating element 130. Considering that the electromagnetic coil also needs to dissipate heat, the second part 142 of the impeller 140 is located outside the heating element 130 so that the air flowing out from the second part 142 can flow in the housing 110, thereby facilitating the airflow to flow through the electromagnetic coil and dissipate heat from the electromagnetic coil, which is beneficial to improving the heat dissipation effect of the electromagnetic coil.

[0063] Combination Figures 1 to 3 The air handling equipment 100 also includes a guide member 150, which is disposed inside the housing 110. At least a portion of the guide member 150 is disposed corresponding to the second portion 142 and extends toward the electromagnetic coil. The guide member 150 is spaced apart from the air outlet 112. The guide member 150 is used to guide the airflow on the air outlet side of the second portion 142 toward the electromagnetic coil.

[0064] In the axial direction of the impeller 140, the guide member 150 is positioned closer to the air inlet 111 than the electromagnetic coil. By positioning at least a portion of the guide member 150 corresponding to the second portion 142, the guide member 150 guides the airflow flowing out of the second portion 142. Furthermore, by extending the guide member 150 toward the electromagnetic coil, the guide member 150 guides the airflow flowing out of the second portion 142 toward the electromagnetic coil, thereby improving the airflow effect toward the electromagnetic coil. This further enhances the heat dissipation effect of the electromagnetic coil, reduces the risk of overheating of the electromagnetic coil, and helps ensure the normal operation of the electromagnetic coil.

[0065] Meanwhile, the air guide 150 and the air outlet 112 are spaced apart to prevent the air guide 150 from blocking the air outlet 112, which helps to ensure the air output efficiency of the air handling equipment 100.

[0066] Optionally, the flow guide 150 can be configured to correspond to the second part 142 as a whole, or the flow guide 150 can extend beyond the second part 142 to the electromagnetic coil. The specific configuration of the flow guide 150 can be determined according to actual production requirements and is not specifically limited here.

[0067] In related technologies, the electromagnetic coil in a space heater has poor heat dissipation and is prone to overheating, which can easily lead to the electromagnetic coil failing to work properly. When the electromagnetic coil malfunctions, the heating element will not be able to generate heat, thus affecting the normal operation of the space heater.

[0068] This application arranges the first part 141 of the impeller 140 inside the heating element 130 and the second part 142 outside the heating element 130, so that the airflow from the second part 142 can flow inside the housing 110, thereby facilitating the airflow to dissipate heat from the electromagnetic coil. By further providing the guide member 150 to guide the airflow from the second part 142 to the electromagnetic coil, the effect of the airflow to the electromagnetic coil is improved, thereby further improving the heat dissipation effect of the electromagnetic coil, reducing the risk of overheating of the electromagnetic coil, ensuring the normal operation of the electromagnetic coil, and thus ensuring the normal operation of the air handling equipment 100.

[0069] The wind turbine 140 can be driven by the first drive device 180, which can be configured as a motor.

[0070] In some other embodiments of this utility model, the heating element 130 can be configured as a component that has a heating function after being powered on, for example, the heating element 130 can be configured as a PTC heating element.

[0071] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the heating element 130 is disposed on the radial inner side of the electromagnetic coil. In the axial direction of the impeller 140, the end of the heating element 130 facing the air inlet 111 is spaced apart from the end of the electromagnetic coil facing the air inlet 111, and the distance between the end of the heating element 130 facing the air inlet 111 and the end of the electromagnetic coil facing the air inlet 111 is St, 5mm≤St≤15mm.

[0072] In other words, the end of the electromagnetic coil facing the air inlet 111 is positioned closer to the air inlet 111 than the end of the heating element 130 facing the air inlet 111, so that part of the airflow entering from the air inlet 111 can flow towards the electromagnetic coil, thereby facilitating the heat dissipation of the electromagnetic coil. By ensuring that the distance St between the end of the heating element 130 facing the air inlet 111 and the end of the electromagnetic coil facing the air inlet 111 satisfies the relationship: 5mm≤St≤15mm, it is possible to facilitate the flow of air towards the electromagnetic coil while preventing the electromagnetic coil from occupying too much air duct space 116 due to its excessive size.

[0073] When St < 5mm, the airflow from the second part 142 is poor in its effect on the electromagnetic coil, resulting in poor heat dissipation of the electromagnetic coil; when St > 15mm, the axial dimension of the electromagnetic coil is too large, resulting in high material cost of the electromagnetic coil, and the electromagnetic coil will occupy the installation space of other components in the air duct space 116.

[0074] Combination Figures 1 to 5 In some embodiments of this utility model, the guide member 150 extends radially outward from the electromagnetic coil in the radial direction of the impeller 140, so that the airflow discharged from the second part 142 can flow along the guide member 150 to the electromagnetic coil, thereby improving the effect of the guide member 150 in guiding the airflow discharged from the second part 142 to the electromagnetic coil, which is beneficial to improving the heat dissipation effect of the airflow on the electromagnetic coil.

[0075] For example, the electromagnetic coil may be entirely located on the radial inner side of the guide member 150, or the end of the electromagnetic coil near the second part 142 in the axial direction of the impeller 140 may be located on the radial inner side of the guide member 150, or the electromagnetic coil and the guide member 150 may be misaligned in the axial direction of the impeller 140, but in the axial projection plane of the impeller 140, the orthogonal projection plane of the electromagnetic coil falls on the radial inner side of the guide member 150.

[0076] It should be noted that the arrangement of the flow guide 150 and the electromagnetic coil can be determined according to actual production requirements, and no specific limitation is made here, as long as the flow guide 150 can guide the airflow to the electromagnetic coil.

[0077] The guide 150 can be constructed as an arc-shaped plate that is recessed in the radial direction of the wind turbine away from the axis of rotation of the wind turbine, which is beneficial to improving the smoothness of airflow when flowing along the guide 150.

[0078] Combination Figure 4 and Figure 5 In some embodiments of this utility model, in the radial direction of the impeller 140, the end of the guide member 150 facing away from the air inlet 111 is flush with the end of the electromagnetic coil facing the air inlet 111. The length of the projection surface of the guide member 150 in the axial direction of the impeller 140 is Sd, 70mm≤Sd≤90mm, so as to ensure the size of the guide member 150, which is beneficial to ensure the guiding effect of the guide member 150 on the airflow, thereby improving the effect of the airflow to the electromagnetic coil.

[0079] When Sd < 70mm, the axial dimension of the guide 150 is too small, resulting in poor guiding effect of the guide 150 on the airflow discharged from the second part 142. Some of the airflow discharged from the second part 142 may flow to the air outlet 112, resulting in poor heat dissipation effect of the airflow on the electromagnetic coil. When Sd > 90mm, the axial dimension of the guide 150 is too large, the space required to arrange the guide 150 is large, and it is easy to increase the volume of the air handling equipment 100.

[0080] Reference Figure 5 In some embodiments of this utility model, the minimum distance between the guide member 150 and the coil module 120 in the radial direction of the impeller 140 is Si, and the value of Si ranges from 8mm to 15mm.

[0081] In other words, in the radial direction of the impeller 140, the guide element 150 and the coil module 120 are spaced apart, so that the airflow can flow through the gap between the guide element 150 and the coil module 120 in the radial direction and pass through the coil module 120. The minimum distance between the guide element 150 and the coil module 120 is Si, and the value of Si is in the range of 8mm to 15mm, so as to ensure the effect of the airflow flowing along the guide element 150 to the coil module 120. This is beneficial to ensure the heat dissipation effect of the airflow on the coil module 120, and at the same time, it is beneficial to reduce the size of the air handling equipment 100 in the radial direction of the impeller 140, thus facilitating the miniaturization design of the air handling equipment 100.

[0082] When Si < 8 mm, the gap between the guide element 150 and the coil module 120 is too small, making it difficult for the airflow to flow through the surface of the coil module 120 opposite to the guide element 150, resulting in poor heat dissipation effect of the airflow on the coil module 120; when Si > 15 mm, the gap between the guide element 150 and the coil module 120 is too large, resulting in a large radial space required for arranging the guide element 150 and the coil module 120, which in turn results in a large radial dimension of the air handling equipment 100.

[0083] In some embodiments of this utility model, in the axial direction of the impeller 140, the air inlet end 151 of the guide member 150 facing the air inlet 111 extends beyond the end of the impeller 140. That is, in the projection plane of the guide member 150 extending from the second part 142, the orthographic projection plane of the second part 142 completely falls within the orthographic projection range of the guide member 150. This is beneficial to ensure the guiding effect of the guide member 150 on the airflow discharged from the second part 142. At the same time, it can also guide part of the airflow entering the housing 110 from the air inlet 111 to the coil module 120, thereby improving the effect of the airflow to the coil module 120 and thus improving the heat exchange effect of the airflow on the coil module 120.

[0084] Or, combine Figure 3 and Figure 5 The air inlet end 151 of the guide element 150 facing the air inlet 111 is flush with the end of the impeller 140. That is, in the projection plane extending from the second part 142 towards the guide element 150, the orthographic projection plane of the second part 142 and the orthographic projection plane of the radially opposite part of the guide element 150 completely coincide. This helps ensure the guiding effect of the guide element 150 on the airflow discharged from the second part 142, thereby improving the airflow towards the coil module 120 and further improving the heat exchange effect of the airflow on the coil. Simultaneously, it helps reduce the material cost of the guide element 150, thus reducing the production cost of the air handling equipment 100.

[0085] It is understandable that the positional relationship between the air inlet end 151 of the guide 150 and the end of the impeller 140 can be determined according to actual production requirements, and no specific limitation is made here.

[0086] Reference Figure 5 In some embodiments of this utility model, the minimum distance between the air inlet end 151 of the guide member 150 and the wind wheel 140 in the radial direction of the impeller 140 is Sb, and the value of Sb ranges from 8mm to 12mm.

[0087] In other words, in the radial direction of the impeller 140, the air inlet end 151 of the guide 150 is spaced apart from the end of the second part 142 near the air inlet 111 to prevent the guide 150 from interfering with the rotation of the impeller 140 due to contact between the air inlet end 151 of the guide 150 and the second part 142. At the same time, it helps to ensure that the guide 150 can effectively guide the airflow discharged from the second part 142, thereby improving the effect of airflow to the coil module 120.

[0088] When Sb < 8 mm, when the air handling equipment 100 shakes, there is a risk that the air inlet end 151 of the guide 150 will come into contact with the second part 142. When Sb > 12 mm, the gap between the air inlet end 151 of the guide 150 and the end of the second part 142 near the air inlet 111 is too large, the guide 150 has a poor guiding effect on the airflow, and the airflow discharged from the second part 142 is easy to flow from the gap between the air inlet end 151 and the end of the second part 142 near the air inlet 111 to the air inlet 111, which can easily lead to airflow backflow, which in turn leads to poor heat dissipation effect of the airflow on the coil module 120.

[0089] Combination Figure 9 and Figure 10 In some embodiments of this utility model, in the axial direction of the impeller 140, the diameter of the second part 142 is D, the diameter of the first part 141 is d, and 0.5≤d / D≤0.9.

[0090] By making the diameter of the second part 142 larger than that of the first part 141, the airflow discharged from the second part 142 can flow through the electromagnetic coil, thereby improving the heat dissipation effect of the impeller 140 on the electromagnetic coil, preventing the electromagnetic coil from overheating, and also ensuring the heat dissipation effect of the impeller 140 on the heat-generating body 130.

[0091] When d / D < 0.5, it is easy to cause poor heat dissipation effect of the first part 141 on the heat source 130, or to cause the diameter of the second part 142 to be too large, thereby increasing the size of the air handling equipment 100. When d / D > 0.9, it is easy to cause poor heat dissipation effect of the second part 142 on the electromagnetic coil, or to cause the diameter of the first part 141 to be too large, thereby causing the gap between the first part 141 and the heat source 130 to be too small, thus affecting the air outlet effect of the first part 141.

[0092] Combination Figure 9 and Figure 10 In some embodiments of this utility model, the axial dimension of the impeller 140 is defined as L, and the axial dimension of the first part 141 is defined as s, 0.4≤s / L≤0.8, which is beneficial to make the axial dimension of the first part 141 match the axial dimension of the heating element 130, and at the same time, it is beneficial to ensure the heat dissipation effect of the impeller 140 on the heating element 130 and the electromagnetic coil.

[0093] Combination Figures 1 to 3 In some embodiments of this utility model, the air handling equipment 100 further includes a first power module 160, which is disposed inside the housing 110 and is connected to an electromagnetic coil to provide alternating current toward the electromagnetic coil.

[0094] For example, the first power module 160 is electrically connected to the electromagnetic coil, and the first power module 160 can supply alternating current to the electromagnetic coil. When the electromagnetic coil is energized, the electromagnetic coil can generate a magnetic field. The heating element 130 can generate heat under the action of the magnetic field to heat the airflow entering the housing 110, thereby realizing the function of the air handling equipment 100 outputting hot air.

[0095] Combination Figures 1 to 3 as well as Figure 6 In some embodiments of this utility model, the second part 142 of the wind turbine 140 is provided with a clearance space 1421 for avoiding the first power module 160.

[0096] For example, at least a portion of the first power module 160 can be located within the clearance space 1421, which helps to reduce the space required within the housing 110 for arranging the first power module 160. It also enables the integration of the first power module 160 and the impeller 140, making the structure of the first power module 160 and the impeller 140 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 reduces the space required for arranging the air handling equipment 100. At the same time, since the clearance space 1421 is located on the second part 142, the first power module 160 can be located outside the heating element 130. This facilitates the installation of the first power module 160 and reduces the impact of the heat generated by the heating element 130 on the first power module 160, thereby reducing the risk of overheating of the first power module 160.

[0097] Optionally, the first power module 160 can be entirely disposed within the clearance space 1421, or the portion of the first power module 160 near the impeller 140 can be disposed within the clearance space 1421. It is understood that the portion of the first power module 160 located within the clearance space 1421 can be determined according to actual production requirements, and no specific limitation is made here.

[0098] like Figure 6 As shown, in some embodiments of the present invention, in the radial direction of the impeller 140, the radially outer ends of some blades of the second part 142 are recessed toward the rotation axis of the impeller 140 to define a clearance space 1421.

[0099] For example, the impeller 140 can be configured as a centrifugal impeller, such that the air inlet and outlet directions of the impeller 140 are mainly axial air inlet and radial air outlet. The clearance space 1421 is set at the air outlet end of the impeller 140. That is, at least part of the clearance space 1421 is located in the air outlet area of ​​the blade. In the radial direction of the impeller 140, the radial dimension of the blade directly opposite the clearance space 1421 is smaller than the radial dimension of the blade that is offset from the clearance space 1421. Thus, by designing the blades of the second part 142, the second part 142 can form a clearance space 1421 that is recessed in the radial direction of the impeller 140, which facilitates the arrangement of the first power module 160 in the clearance space 1421, realizing the integration of the first power module 160 with the impeller 140, and at the same time, it facilitates the air discharged from the second part 142 to dissipate heat from the first power module 160.

[0100] Combination Figure 3 and Figure 6 In some embodiments of this utility model, the portion of the first power module 160 located within the clearance space 1421 is spaced apart from the inner wall of the clearance space 1421.

[0101] Since the clearance space 1421 is located on the second part 142, and the inner wall of the clearance space 1421 is part of the impeller 140, in order to prevent the first power module 160 from interfering with the operation of the impeller 140 due to contact between the first power module 160 and the inner wall of the clearance space 1421, it is necessary to set a gap between the part of the first power module 160 located in the clearance space 1421 and the inner wall of the clearance space 1421. This reduces the risk of the first power module 160 interfering with the operation of the impeller 140, improves the smoothness of the operation of the impeller 140, and thus helps to ensure the efficiency of the impeller 140 in driving airflow.

[0102] Combination Figure 3 and Figure 6 In some embodiments of this utility model, in the axial direction of the impeller 140, the distance between any side of the portion of the first power module 160 located in the clearance space 1421 and the clearance space 1421 is a first distance S1, where S1 > 8 mm.

[0103] Considering that the first power module 160 is prone to move in the axial direction of the impeller 140 when the air handling equipment 100 shakes, by making S1 > 8mm, sufficient movement space is reserved for the first power module 160 in the axial direction of the impeller 140. This helps to further reduce the risk of the first power module 160 contacting the inner wall of the clearance space 1421, thereby further reducing the risk of the first power module 160 interfering with the operation of the impeller 140.

[0104] Combination Figure 3 and Figure 6 In some embodiments of this utility model, in the radial direction of the impeller 140, the distance between the portion of the first power module 160 located in the clearance space 1421 and the clearance space 1421 is the second distance S2, where S2 > 8 mm.

[0105] Considering that the first power module 160 may move in the radial direction of the impeller 140 when the air handling equipment 100 shakes, by making S2 > 8mm, sufficient movement space is reserved for the first power module 160 in the radial direction of the impeller 140. This helps to further reduce the risk of the first power module 160 contacting the inner wall of the clearance space 1421, thereby further reducing the risk of the first power module 160 interfering with the operation of the impeller 140.

[0106] Combination Figure 3 and Figure 6 In some embodiments of this utility model, the second part 142 supplies air toward the first power module 160.

[0107] In other words, the clearance space 1421 can be set on the air outlet side of the second part 142 so that the first power module 160 can be set on the air outlet side of the second part 142. The airflow discharged from the second part 142 can flow to the first power module 160, so as to achieve the effect of the second part 142 supplying air to the first power module 160. By making the second part 142 supply air to the first power module 160, the airflow can dissipate heat from the first power module 160, which helps to reduce the risk of the first power module 160 overheating.

[0108] Combination Figures 1 to 3 In some embodiments of this utility model, the housing 110 has a heat dissipation area 115, which is correspondingly arranged with the first power module 160, and the airflow flowing through the first power module 160 flows outward through the heat dissipation area 115.

[0109] For example, a duct space 116 is formed inside the housing 110, which connects the air inlet 111 and the air outlet 112. The impeller 140, the first power module 160 and the coil module 120 are all arranged in the duct space 116. The heat dissipation area 115 is connected to the duct space 116 and can be arranged directly opposite the first power module 160.

[0110] After the second part 142 discharges the airflow, the airflow can flow through the first power module 160 and dissipate heat from the first power module 160. The airflow that has exchanged heat with the first power module 160 can be further discharged from the air duct space 116 through the heat dissipation area 115, which is beneficial to improving the heat dissipation efficiency of the first power module 160.

[0111] The heat dissipation area 115 can be formed at the bottom of the housing 110, that is, the heat dissipation area 115 is set downward to prevent debris (such as dust and water) from entering the housing 110 through the heat dissipation area 115 and affecting the operation of the internal components of the housing 110. Correspondingly, since the first power module 160 is set in correspondence with the heat dissipation area 115, the first power module 160 can be set in the lower region of the second part 142 in the air duct space 116.

[0112] Combination Figures 1 to 3 In some embodiments of this utility model, the heat dissipation area 115 includes a plurality of spaced through holes 1151.

[0113] The through hole 1151 is provided through the housing 110 along the thickness direction of the housing 110. It can also be understood that the through hole 1151 is provided through the housing 110 along the radial direction of the impeller 140. Multiple through holes 1151 are arranged at intervals along the axial and circumferential directions of the impeller 140 on the housing 110. That is, multiple through holes 1151 are arranged in an array on the housing 110 and are all connected to the air duct space 116. By providing multiple through holes 1151, it is beneficial to improve the efficiency of airflow discharge after heat exchange with the first power module 160, thereby further improving the heat dissipation efficiency of the first power module 160.

[0114] like Figure 3 As shown, in some embodiments of this utility model, the first power module 160 and the flow guide 150 are distributed on both sides of the wind turbine 140 in the radial direction.

[0115] For example, the impeller 140 can be configured as a centrifugal impeller, and the clearance space 1421 can be set on the outer peripheral wall of the second part 142 to realize the arrangement of the first power module 160 on the radial side of the impeller 140, while facilitating the second part 142 to deliver air toward the first power module 160. The guide member 150 is located on the side of the impeller 140 that is radially away from the first power module 160, so that the guide member 150 can avoid the first power module 160, preventing the guide member 150 and the first power module 160 from interfering with each other, facilitating the arrangement of the first power module 160 and the guide member 150, and at the same time helping to prevent the first power module 160 from affecting the airflow guiding effect of the guide member 150.

[0116] Combination Figure 1 , Figure 3 and Figure 5 In some embodiments of this utility model, the heating element 130 is formed as a hollow cylinder and is sleeved on the first part 141, and a cylindrical airflow channel 131 is defined inside the heating element 130.

[0117] By forming the heating element 130 into a hollow cylindrical shape, the heating area of ​​the heating element 130 is increased, thereby improving the efficiency of the heating element 130 in generating heat. At the same time, a cylindrical airflow channel 131 is defined inside the heating element 130. The first part 141 is disposed in the airflow channel 131. While the first part 141 drives the airflow in the airflow channel 131, the heating element 130 can restrict the airflow from diverging in the radial direction of the first part 141, which is beneficial to improving the efficiency of the airflow to the air outlet 112, thereby improving the efficiency of the air handling equipment 100 in outputting hot air.

[0118] Combination Figures 1 to 5In some embodiments of this utility model, the coil module 120 includes a coil bracket 121 for fixing the electromagnetic coil, and the heating element 130 is fixed to the coil bracket 121.

[0119] For example, the coil support 121 can be formed into a ring and sleeved onto the heating element 130. The coil support 121 can provide stable support for the electromagnetic coil, which is beneficial to improving the assembly stability of the electromagnetic coil. At the same time, the heating element 130 is fixed to the coil support 121, which can provide stable support for the heating element 130, which is beneficial to improving the assembly stability of the heating element 130. Thus, modular assembly of the heating element 130 and the coil module 120 is realized, which is beneficial to improving the assembly efficiency of the air handling equipment 100.

[0120] Combination Figures 1 to 3 In some specific embodiments, in the radial direction of the impeller 140, the coil support 121 is provided with a plurality of winding protrusions 1211 on the side away from the heating element 130 (i.e., the outer peripheral wall of the coil support 121). The plurality of winding protrusions 1211 are arranged at intervals in the axial direction of the impeller 140, and a winding groove is formed between two adjacent winding protrusions 1211. The electromagnetic coil can be mounted on the coil support 121 through the plurality of winding grooves to improve the assembly reliability of the electromagnetic coil and the coil support 121.

[0121] In some embodiments of this utility model, the air handling equipment 100 further includes a shielding component, which is disposed between the housing 110 and the coil module 120, and the shielding component is made of magnetic material.

[0122] 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 130 in the radial direction of the impeller 140, causing magnetic field leakage, a shielding component is set between the coil module 120 and the housing 110 to reduce the amount of magnetic field leakage on the side of the electromagnetic coil away from the heating element 130. This also helps to increase the magnetic field strength on the side of the electromagnetic coil close to the heating element 130, thereby improving the heating effect of the heating element 130 and thus improving the efficiency of the air handling equipment 100 in outputting hot air.

[0123] 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.

[0124] Combination Figures 1 to 8 In some embodiments of this utility model, the air handling equipment 100 further includes a fixed bracket 170, which is fixed to the housing 110, and the shield and the air guide 150 are respectively fixed to the fixed bracket 170.

[0125] For example, a mounting groove 171 is formed on the fixed bracket 170, and the shielding component can be embedded in the mounting groove 171 so that the shielding component can be fixed to the fixed bracket 170, thereby improving the installation reliability of the shielding component. At the same time, the flow guide 150 is fixedly connected to the fixed bracket 170. The shielding component, the fixed bracket 170 and the flow guide 150 can be modularly assembled, which is beneficial to improving the assembly convenience of the air handling equipment 100, thereby improving the assembly efficiency of the air handling equipment 100.

[0126] Combination Figure 7 and Figure 8 In some embodiments of this utility model, the fixed bracket 170 and the flow guide 150 are integrated as one piece, and there is no need to assemble the fixed bracket 170 and the flow guide 150 separately. When the shield is installed on the fixed bracket 170, the shield can be modularly assembled with the fixed bracket 170 and the flow guide 150, which is conducive to further improving the assembly convenience of the air handling equipment 100.

[0127] In some other embodiments of this utility model, the flow guide 150 can be integrated with the housing 110, eliminating the need for separate assembly of the flow guide 150, and facilitating the positioning of the impeller 140 and the first power module 160, thereby improving the assembly convenience of the air handling equipment 100.

[0128] Combination Figures 1 to 3 In some embodiments of this utility model, the housing 110 includes a housing body 113, on which an air inlet 111 and an air outlet 112 are formed respectively. Components such as the heating element 130, coil module 120, impeller 140, shielding component, fixing bracket 170, and first power module 160 can all be arranged inside the housing body 113. The housing body 113 can provide positioning support for the components arranged therein, which is beneficial to improving the structural stability of the air handling equipment 100. In addition, the housing body 113 can protect the above-mentioned components, which is beneficial to reducing the risk of damage to components such as the impeller 140, thereby improving the service life of the air handling equipment 100.

[0129] Combination Figures 1 to 3 In some embodiments of this utility model, an air inlet screen 114 is provided at the air inlet 111 of the shell body 113. The air inlet screen 114 is detachably mounted on the shell body 113 so that the user can remove the air inlet screen 114 for cleaning, and at the same time facilitate the cleaning and maintenance of the structure inside the shell body 113.

[0130] 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.

[0131] The following describes two assembly methods of the air handling equipment 100 based on the structure of the air handling equipment 100 according to an embodiment of the present invention.

[0132] Assembly Method 1: The electromagnetic coil is mounted on the coil bracket 121, and the heating element 130 is fixedly connected to the coil bracket 121. The fixing bracket 170 and the guide component 150 are integrated. The shielding component can be installed on the fixing bracket 170. The fixing bracket 170 is sleeved on the radially outer side of the coil bracket 121 and fixedly connected to the coil bracket 121. The impeller 140 can be positioned in the center area of ​​the heating element 130 by hand. The first power module 160 is arranged in the clearance space 1421 and... The first power module 160 is fixedly connected to the fixed bracket 170, thereby realizing the modular assembly of the heating element 130, coil module 120, fixed bracket 170, shielding component, first power module 160 and impeller 140. Then, the above components are placed into the housing body 113, and the coil bracket 121 and impeller 140 are further connected to the housing body 113 respectively. Finally, the air inlet mesh cover 114 is installed at the air inlet 111 of the housing body 113 to complete the assembly of the air handling equipment 100.

[0133] In order to ensure the assembly reliability of the components inside the shell body 113 with the shell body 113, the fixing bracket 170 can be further connected to the shell body 113 to reduce the risk of the components inside the shell body 113 falling off the shell body 113.

[0134] Assembly Method 2: First, the heating element 130 is fixedly installed inside the shell body 113. Then, the coil bracket 121 with the electromagnetic coil installed is fitted on the radial outer side of the heating element 130, and the coil bracket 121 is fixedly connected to the shell body 113. Then, the integral piece formed by the fixing bracket 170 and the guide 150 is fitted on the radial outer side of the coil bracket 121 and fixedly connected to the shell body 113. Then, the impeller 140 is positioned and installed in the central area of ​​the heating element 130. The first power module 160 can be installed on the fixing bracket 170 or the shell body 113. Finally, the air inlet mesh cover 114 is installed at the air inlet 111 of the shell body 113 to complete the assembly of the air handling equipment 100.

[0135] The first power module 160 can be pre-installed on the fixed bracket 170, which helps to improve the installation convenience of the first power module 160 and the fixed bracket 170.

[0136] It should be noted that the above-mentioned fixed connection methods can all use threaded connectors to fix the components together, so as to facilitate the disassembly, maintenance and cleaning of the air handling equipment 100. Of course, it is understood that the fixed connection methods include but are not limited to connecting with threaded connectors, and can also be snap-fit, etc. The specific fixed connection method can be determined according to the actual production requirements, and no specific limitation is made here.

[0137] Combination Figures 1 to 3 According to an embodiment of the present invention, an air handling device includes a housing 110 and a centrifugal impeller 140. The housing 110 is provided with an air inlet 111 and an air outlet 112. Air can enter the housing 110 through the air inlet 111. The centrifugal impeller 140 is disposed inside the housing 110. After the air enters the housing 110 through the air inlet 111, the centrifugal impeller 140 can drive the air entering the housing 110 to flow from the air inlet 111 to the air outlet 112, so as to improve the air flow efficiency inside the housing 110.

[0138] The air handling unit 100 also includes a heating element 130, which is disposed inside the housing 110. The heating element 130 can generate heat to heat the air entering the housing 110. The heated air can be discharged from the air handling unit 100 through the air outlet 112, thereby realizing the function of the air handling unit 100 outputting hot air.

[0139] In the axial direction of the centrifugal impeller 140, the first part 141 of the centrifugal impeller 140 is located inside the heating element 130 to deliver air toward the inner wall of the heating element 130, and the second part 142 of the centrifugal impeller 140 is located outside the heating element 130.

[0140] Specifically, the centrifugal impeller 140 has an axial air intake and a radial air outlet. By placing the first part 141 inside the heating element 130, the airflow discharged from the first part 141 can flow towards the inner wall of the heating element 130 to dissipate heat from the inner wall of the heating element 130.

[0141] Considering that the outer wall of the heating element 130 also needs to dissipate heat, the second part 142 of the centrifugal impeller 140 is arranged outside the heating element 130 so that the airflow discharged from the second part 142 can flow inside the housing 110. This facilitates the airflow discharged from the second part 142 to flow over the outer wall of the heating element 130 and dissipate heat from the outer wall of the heating element 130, which helps to improve the heat dissipation uniformity of the heating element 130, prevents the heating element 130 from overheating locally, and helps to improve the efficiency of the air handling equipment 100 in outputting hot air.

[0142] It should be noted that "the inner wall of the heating element 130" refers to the side wall of the heating element 130 opposite to the first part 141 in the radial direction of the centrifugal impeller 140, and "the outer wall of the heating element 130" refers to the side wall of the heating element 130 away from the first part 141 in the radial direction of the centrifugal impeller 140.

[0143] Combination Figures 1 to 3 The air handling equipment 100 also includes a guide member 150, which is disposed inside the housing 110. At least a portion of the guide member 150 is disposed corresponding to the second portion 142 and extends radially outward toward the heating element 130. The guide member 150 is spaced apart from the air outlet 112. The guide member 150 is used to guide the airflow on the air outlet side of the second portion 142 toward the radial outward of the heating element 130.

[0144] By configuring at least a portion of the guide member 150 to correspond to the second portion 142, the guide member 150 guides the airflow flowing out of the second portion 142. By further extending the guide member 150 towards the radially outer side of the heating element 130, the guide member 150 guides the airflow flowing out of the second portion 142 towards the radially outer side of the heating element 130. This improves the effect of the airflow flowing towards the outer wall of the heating element 130, allowing the airflow to dissipate heat from the outer wall of the heating element 130. This further improves the heat dissipation effect of the outer wall of the heating element 130, reduces the risk of local overheating of the heating element 130, and improves the efficiency of the air handling equipment 100 in outputting hot air.

[0145] Meanwhile, the air guide 150 and the air outlet 112 are spaced apart to prevent the air guide 150 from blocking the air outlet 112, which helps to ensure the air output efficiency of the air handling equipment 100.

[0146] Optionally, the flow guide 150 can be configured to correspond to the second part 142 as a whole, or the flow guide 150 can extend beyond the second part 142 to the outer wall of the heating element 130. The specific structure of the flow guide 150 can be determined according to actual production requirements, and is not specifically limited here.

[0147] According to the embodiment of the present invention, the air handling equipment 100 has a first part 141 of the centrifugal impeller 140 disposed inside the heating element 130 and a second part 142 disposed outside the heating element 130. This allows the airflow from the second part 142 to flow within the housing 110, thereby facilitating heat dissipation from the airflow to the outer wall of the heating element 130. By further providing a guide member 150 to guide the airflow from the second part 142 to the outer wall of the heating element 130, the effect of airflow to the outer wall of the heating element 130 is improved, thereby improving the uniformity of heat dissipation from the heating element 130, reducing the risk of local overheating of the heating element 130, and improving the efficiency of the air handling equipment 100 in outputting hot air.

[0148] like Figure 3 As shown, the air handling device 100 according to an embodiment of the present invention includes: a housing 110 and a fan 140. The housing 110 is provided with an air inlet 111 and an air outlet 112. Air can enter the housing 110 through the air inlet 111. The fan 140 is disposed inside the housing 110. After the air enters the housing 110 through the air inlet 111, the fan 140 can drive the air entering the housing 110 to flow from the air inlet 111 to the air outlet 112, so as to improve the air flow efficiency inside the housing 110.

[0149] Combination Figures 1 to 3 The air handling equipment 100 also includes a coil module 120 and a heating element 130. The coil module 120 is disposed inside the housing 110 and includes an electromagnetic coil capable of generating a magnetic field. The heating element 130 is disposed inside the housing 110 and is configured to generate heat under the action of the magnetic field of the electromagnetic coil.

[0150] Electromagnetic induction heating can be achieved through the cooperation of electromagnetic coil and heating element 130. Electromagnetic induction heating has the advantages of uniform heating and rapid response, which helps to improve the heating efficiency of heating element 130. Since heating element 130 is set inside housing 110, heating element 130 can heat the air entering housing 110 so that air handling equipment 100 can output hot air.

[0151] In the axial direction of the impeller 140, the first part 141 of the impeller 140 is located inside the heating element 130 so that the first part 141 can send air to the inner wall of the heating element 130, thereby facilitating the heat dissipation of the heating element 130. Considering that the electromagnetic coil also needs to dissipate heat, the second part 142 of the impeller 140 is located outside the heating element 130 so that the air flowing out from the second part 142 can flow in the housing 110, thereby facilitating the airflow to flow through the electromagnetic coil and dissipate heat from the electromagnetic coil, which is beneficial to improving the heat dissipation effect of the electromagnetic coil.

[0152] Reference Figure 3A portion of the housing 110 defines a guide 150, which is disposed within the housing 110. At least a portion of the guide 150 is disposed corresponding to the second portion 142 and extends toward the electromagnetic coil. The guide 150 is spaced apart from the air outlet 112. The guide 150 is used to guide the airflow on the air outlet side of the second portion 142 toward the electromagnetic coil.

[0153] By configuring at least a portion of the flow guide 150 to correspond to the second portion 142, the flow guide 150 can guide the airflow flowing out of the second portion 142. By further extending the flow guide 150 toward the electromagnetic coil, the flow guide 150 can guide the airflow flowing out of the second portion 142 toward the electromagnetic coil, which helps to improve the effect of airflow toward the electromagnetic coil, thereby further improving the heat dissipation effect of the electromagnetic coil, reducing the risk of overheating of the electromagnetic coil, and helping to ensure the normal operation of the electromagnetic coil.

[0154] Meanwhile, the air guide 150 and the air outlet 112 are spaced apart to prevent the air guide 150 from blocking the air outlet 112, which helps to ensure the air output efficiency of the air handling equipment 100.

[0155] Furthermore, by defining the air guide 150 by a portion of the housing 110, the assembly steps of the air handling equipment 100 are simplified, thereby improving the production efficiency of the air handling equipment 100.

[0156] Optionally, the flow guide 150 can be configured to correspond to the second part 142 as a whole, or the flow guide 150 can extend beyond the second part 142 to the electromagnetic coil. The specific configuration of the flow guide 150 can be determined according to actual production requirements and is not specifically limited here.

[0157] In related technologies, the electromagnetic coil in a space heater has poor heat dissipation and is prone to overheating, which can easily lead to the electromagnetic coil failing to work properly. When the electromagnetic coil malfunctions, the heating element will not be able to generate heat, thus affecting the normal operation of the space heater.

[0158] This application arranges the first part 141 of the impeller 140 inside the heating element 130 and the second part 142 outside the heating element 130, so that the airflow from the second part 142 flows within the housing 110, thereby facilitating the airflow to dissipate heat from the electromagnetic coil. By defining a guide 150 within a portion of the housing 110, the airflow from the second part 142 is guided towards the electromagnetic coil, which improves the airflow effect towards the electromagnetic coil, thereby further improving the heat dissipation effect of the electromagnetic coil, reducing the risk of overheating of the electromagnetic coil, ensuring the normal operation of the electromagnetic coil, and thus ensuring the normal operation of the air handling equipment 100. It also simplifies the assembly steps of the air handling equipment 100, thereby improving the production efficiency of the air handling equipment 100.

[0159] like Figure 11 As shown, the heater 200 according to an embodiment of the present utility model includes the air handling device 100 described above.

[0160] Since the heater 200 is equipped with the aforementioned air handling equipment 100, by placing the first part 141 of the impeller 140 inside the heating element 130 and the second part 142 outside the heating element 130, the airflow from the second part 142 can flow within the housing 110, thereby facilitating the airflow to dissipate heat from the electromagnetic coil. By further providing the guide member 150, the airflow from the second part 142 is guided towards the electromagnetic coil, which helps to improve the airflow effect towards the electromagnetic coil, thereby further improving the heat dissipation effect of the electromagnetic coil, reducing the risk of overheating of the electromagnetic coil, ensuring the normal operation of the electromagnetic coil, and thus helping to ensure the normal operation of the air handling equipment 100.

[0161] Reference Figure 10 In some embodiments of this utility model, the heater 200 also includes a bracket 210, and the air handling unit 100 is swayably mounted on the bracket 210.

[0162] 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 also provided on the base 220. The second driving device can drive the bracket 210 to swing 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 drives the air handling equipment 100 to swing up and down.

[0163] Optionally, the vertical swing 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 swing up and down or left and right.

[0164] The second drive unit can be configured as a drive motor.

[0165] 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.

[0166] When the heater 200 is in cold air operation mode, the fan wheel 140 can be started, while the heating element 130 does not work, so as to ensure that the heater 200 can provide clean cold air. This makes the heater 200 suitable for cooling high-temperature environments and helps to reduce the energy consumption of the heater 200.

[0167] When the heater 200 is in the warm air operation mode, the fan wheel 140 and the heating element 130 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.

[0168] 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 cold air operation mode of the heater 200 has more speed settings than 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 cold air operation mode of the heater 200 can have 8 speed settings, and the warm air operation mode can have 3 speed settings. When the heater 200 switches directly from the 3rd speed setting in the cold air 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.
