Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, an air handling device 100 includes: a housing 10, a coil module 50, a heating element 20, and a fan 30. The housing 10 is provided with an air inlet 101 and an air outlet 102. The coil module 50 is disposed inside the housing 10 and includes an electromagnetic coil 52 capable of generating a magnetic field. The heating element 20 is configured to generate heat under the action of a magnetic field. The heating element 20 can be a conductor or an conductive material to generate heat under the action of a magnetic field. Specifically, when the electromagnetic coil 52 is energized, the electromagnetic field generated acts on the heating element 20, causing the heating element 20 to generate eddy currents and thus generate heat, enabling the heating element 20 to heat the air. This achieves electromagnetic induction heating, which has advantages such as uniform heating and rapid response, and is beneficial for improving heating efficiency.

[0033] Furthermore, the impeller 30 is disposed inside the housing 10 to create a negative pressure at its air inlet side, thereby driving the air entering from the air inlet 101 to flow through the heating element 20 and toward the air outlet 102. The airflow can exchange heat with the heating element 20 and then flow out from the air outlet 102, thereby increasing the air outlet temperature.

[0034] Furthermore, the housing 10 has a heat dissipation channel 13 for cooling the electromagnetic coil 52. The inlet end 103 of the heat dissipation channel 13 is connected to the air inlet 101, allowing airflow to enter the inlet end 103 of the heat dissipation channel 13 from the air inlet 101. The outlet end 104 of the heat dissipation channel 13 is located on the air inlet side of the impeller 30. Utilizing the negative pressure formed by the impeller 30 on the air inlet side, the airflow in the heat dissipation channel 13 can be guided towards the outlet end 104. Thus, the airflow can flow from the inlet end 103 to the outlet end 104 of the heat dissipation channel 13. During this flow, the airflow can pass through the electromagnetic coil 52, exchanging heat with it and carrying away its heat. This helps reduce the heat of the coil module 50, thereby preventing localized overheating and improving operational safety. In addition, the airflow passing through the electromagnetic coil 52 can also heat the airflow, thereby improving the heating effect of the air handling equipment 100 and increasing the outlet air temperature.

[0035] The air handling device 100 according to an embodiment of the present invention mainly includes a coil module 50, a heating element 20, and a fan wheel 30. When the fan wheel 30 is running, it can create a negative pressure at the air inlet side. Under the action of the negative pressure, the fan wheel 30 can guide the airflow from the air inlet 101 through the heating element 20 and out of the air outlet 102, realizing heat exchange between the airflow and the heating element 20. The fan wheel 30 can also guide the airflow from the air inlet 101 into the inlet end 103 of the heat dissipation channel 13, through the electromagnetic coil 52, and out of the outlet end 104 of the heat dissipation channel 13, realizing heat dissipation of the electromagnetic coil 52 and heating of the airflow, which is beneficial to improving the heat dissipation effect and the outlet air temperature of the air handling device 100.

[0036] Combination Figure 2 In some embodiments of this utility model, the air handling device 100 further includes a coil cover 40, which covers the coil module 50. The heat dissipation channel 13 includes an air inlet section 131 and a heat dissipation section 132. The air inlet section 131, which communicates with the air inlet 101, is defined between the coil cover 40 and the inner peripheral wall of the housing 10. The heat dissipation section 132 is defined between the coil cover 40 and the coil module 50. One end of the heat dissipation section 132 communicates with the air inlet section 131, and the other end extends toward the outlet end 104. Specifically, airflow can enter the air inlet section 131 from the air inlet 101 and then enter the heat dissipation section 132. In the heat dissipation section 132, the airflow flows over the surface of the coil module 50, which can carry away the heat of the electromagnetic coil 52. Then, it flows out from the outlet end 104, sending out the heat-exchanged airflow and increasing the outlet air temperature.

[0037] The coil cover 40 can form an air inlet section 131 and a heat dissipation section 132 between the inner side of the housing 10 and the outer side of the coil module 50. This allows for better control of the airflow area in the heat dissipation section 132, thereby improving the heat dissipation effect on the electromagnetic coil 52. It can also extend the airflow path, thereby increasing the contact time between the airflow and the surface of the electromagnetic coil 52, which helps to improve the heat dissipation effect. In addition, the coil cover 40 can reduce airflow interference from the air inlet 101 to the air outlet 102, which is conducive to improving the airflow effect within the heat dissipation channel 13.

[0038] Combination Figure 2 In some embodiments of this invention, a portion of the coil cover 40 is located between the impeller 30 and the air inlet 101 in the axial direction of the impeller 30, and defines an outlet end 104 with the coil module 50. Specifically, by directly utilizing the coil cover 40 and the coil module 50 to construct the outlet end 104, the structure can be simplified, which helps to reduce wind resistance. The outlet end 104 is located between the impeller 30 and the air inlet 101, so that the outlet end 104 can be connected to the negative pressure zone formed by the impeller 30, so that the suction force formed by the negative pressure zone can act on the outlet end 104, thereby guiding the airflow from the outlet end 104 to the air outlet 102.

[0039] More specifically, in some embodiments of this utility model, the opening of the outlet end 104 is arranged facing the air inlet side of the impeller 30, which can improve the suction power of the impeller 30 on the airflow at the outlet end 104 when it is working, thereby improving the airflow conduction effect and improving energy utilization.

[0040] Combination Figure 3 In some embodiments of this utility model, the coil cover 40 includes: an annular cover 41, an annular guide portion 42, and a connecting portion 43. In the radial direction of the impeller 30, the cover 41 covers the coil module 50. An air inlet section 131 is defined between the cover 41 and the housing 10. A first portion 1321 of a heat dissipation section 132 is defined between the cover 41 and the coil module 50. In the axial direction of the impeller 30, the guide portion 42 is located between the impeller 30 and the air inlet 101 to guide the airflow from the air inlet 101 to the impeller 30. An outlet end 104 is defined between the guide portion 42 and the coil module 50. The connecting portion 43 is connected to the cover 41 and the guide portion 42 respectively. A second portion 1322 of the heat dissipation section 132 is defined between the connecting portion 43 and the coil module 50. The second portion 1322 is connected to the first portion 1321 and the outlet end 104 respectively. In addition, the outer cover of the cover 41, along with the coil module 50 and the heating element 20, can also provide some protection.

[0041] Specifically, the cover 41 can cooperate with the housing 10 and the coil module 50 to construct two flow channels within the heat dissipation channel 13, namely the air inlet section 131 and the heat dissipation section 132. The airflow first passes through the air inlet section 131 and then enters the heat dissipation section 132, which can improve the stability of the airflow within the heat dissipation section 132, thereby improving the heat dissipation effect. The connecting part 43 connects between the cover 41 and the guide part 42, and can work with the coil module 50 to construct a meandering flow channel, namely the first part 1321 and the second part 1322 of the heat dissipation section 132. The first part 1321 of the heat dissipation section 132 is the main part, used for heat exchange with the coil module 50. The second part 1322 of the heat dissipation section 132 is connected to the first part 1321, and the second part 1322 can guide the airflow to the outlet end 104. Therefore, in conjunction with the foregoing, one end of the first part 1321 of the heat dissipation section 132 is connected to the air inlet section 131, and the other end is connected to the second part 1322 of the heat dissipation section 132. In this way, the first part 1321 used for heat exchange with the coil module 50 is not easily affected by the airflow at the inlet end 103 and the outlet end 104. The airflow path can be optimized, the stability of the airflow flowing through the electromagnetic coil 52 can be improved, thereby improving the heat dissipation effect on the electromagnetic coil 52.

[0042] In some embodiments of this invention, the cross-sectional area of ​​the guide portion 42 gradually decreases in the direction from the air inlet 101 to the impeller 30. Specifically, the guide portion 42 can guide airflow from the air inlet 101 into the housing 10. Especially near the air inlet 101, the guide portion 42, which extends obliquely towards the air inlet 101, can improve the stability of airflow entry, thereby improving suction efficiency. Furthermore, the guide portion 42, extending obliquely along the axial direction, can also guide the outlet end 104 of the heat dissipation channel 13 towards the impeller 30. In the radial direction of the impeller 30, the guide portion 42 separates the air inlet 101 from the outlet end 104 of the heat dissipation channel 13, which can prevent the airflow from interfering with each other and improve the stability of gas flow.

[0043] In some embodiments of this utility model, the coil cover 40 is an integral piece, which can improve airtightness, thereby improving the flow guiding effect, and is convenient for manufacturing and assembly.

[0044] Alternatively, the coil cover 40 can also be constructed as an integral structure with the housing 10.

[0045] In some embodiments of this invention, the connection between the heat dissipation section 132 and the air inlet section 131 is located radially outside the coil module 50 in the radial direction of the impeller 30; the connection and the outlet end 104 are located at opposite ends of the axial direction of the impeller 30, respectively. This extends the airflow path within the heat dissipation section 132, allowing it to completely cover the axial dimensions of the coil module 50, thereby improving the heat dissipation effect of the airflow in the heat dissipation section 132 on the electromagnetic coil 52 of the coil module 50. Specifically, the airflow in the air inlet section 131 can enter the heat dissipation section 132 from the connection and extend radially to the outlet end 104. Since the connection and the outlet end 104 are located at opposite ends of the axial direction of the coil module 50, the airflow can fully contact the coil module 50 during flow, improving the heat exchange effect.

[0046] Combination Figure 4 In some embodiments of this utility model, the heating element 20 has a cylindrical structure, which is beneficial for increasing the heating area of ​​the heating element 20 and improving the heating effect. Furthermore, the cylindrical structure can adapt to the shape of the air handling equipment 100, facilitating its arrangement and improving the structural compactness of the equipment layout. Further, the inner peripheral wall of the heating element 20 defines airflow channels 210 that communicate with the air inlet 101 and the air outlet 102 respectively. Thus, when the impeller 30 guides air from the air inlet 101 into the air handling equipment 100 and flows through the heating element 20, the heating element 20 itself also has a guiding effect, allowing it to simultaneously heat the air and guide its flow. Therefore, there is no need to set up a separate guiding component for the heating element, which simplifies the structure. Furthermore, eliminating the need for a separate guiding structure also reduces wind resistance and minimizes friction loss.

[0047] Furthermore, at least a portion of the impeller 30 is located within the airflow channel 210, which can shorten the axial dimension of the air handling equipment 100, thereby improving the structural compactness of the equipment and facilitating its miniaturization. In addition, when the impeller 30 is in operation, it can directly supply air to the airflow channel 210, thereby improving the heat exchange effect with the inner wall of the heating element 20 and increasing the outlet air temperature.

[0048] In some embodiments of this utility model, the impeller 30 is a centrifugal impeller 30, which delivers air towards the inner peripheral wall of the heating element 20. By intake of air on the axial rear side of the centrifugal impeller 30 and exhaust of air radially, the outflowing air can be directly blown towards the heating element 20, thereby realizing the outflow of hot air. Specifically, the outlet airflow is thrown out under the action of centrifugal force, so that the air outlet of the impeller 30 can circulate fully within the airflow channel 210.

[0049] In some embodiments of this utility model, the impeller 30 is located entirely within the airflow channel 210, which can improve the heat exchange effect between the airflow and the heating element 20, and also reduce the axial dimension of the air handling equipment 100.

[0050] Combination Figure 3 In some embodiments of this utility model, the air inlet 101 includes an outer ring portion 111 and an inner ring portion 112, with the outer ring portion 111 surrounding the outer periphery of the inner ring portion 112. Along the axial direction of the impeller 30, the airflow channel 210 is correspondingly arranged with the inner ring portion 112. After entering the housing 10 from the inner ring portion 112, the airflow can enter the airflow channel 210 axially, which helps optimize the airflow path and reduce energy loss. The inlet end 103 of the heat dissipation channel 13 is the outer ring portion 111. After entering the housing 10 from the outer ring portion 111, the airflow can enter the airflow channel 210 axially, which helps optimize the airflow path and reduce energy loss. Alternatively, the airflow can enter the heat dissipation channel 13 and the airflow channel 210 from different areas of the air inlet 101, and exchange heat with the coil module 50 and the heating element 20 respectively, which can improve the heat exchange and heat dissipation effect.

[0051] In some embodiments of this utility model, in the axial direction of the impeller 30, the outer ring portion 111 is located on the side of the inner ring portion 112 facing the air intake side of the impeller 30. When the impeller 30 is working, the negative pressure formed on the air intake side can guide air from the outer ring portion 111 and the inner ring portion 112 into the housing 10, thereby improving the air conduction effect.

[0052] Combination Figure 4 In some embodiments, an air inlet screen 11 is provided at the air inlet 101 of the housing 10, and an air outlet screen 12 is provided at the air outlet 102 of the housing 10. The impeller 30 is used to drive the air outside the housing 10 to enter the housing 10 through the air inlet screen 11, then exchange heat with the heating element 20, and finally blow it out through the air outlet screen 12.

[0053] At least one of the air inlet screen 11 and the air outlet screen 12 is detachably mounted on the housing 10, allowing users to remove the air inlet screen 11 and / or the air outlet screen 12 for cleaning. This also facilitates cleaning and maintenance of the internal structure of the housing 10, improving the ease of use of the air handling equipment 100. In some specific embodiments, the air inlet screen 11 is detachably mounted on the housing 10, and the air outlet screen 12 is integrally formed with the housing 10.

[0054] According to the air conditioning device 100 proposed in this invention, the coil module 50 can convert electrical energy into heat energy. The coil module 50 is correspondingly arranged with the heating element 20, and the coil module 50 can raise the temperature of the heating element 20. Specifically, the heating element 20 can be a conductor or conductive body with free charges that can be driven to heat by the magnetic field generated by the coil. For example, it can be iron with a magnetic material or aluminum with a non-magnetic material. The coil module 50 and the heating element 20 are correspondingly arranged. The electromagnetic coil 52 of the coil module 50 can realize electromagnetic induction heating, which has the advantages of uniform heating and fast response, and is conducive to improving heating efficiency and controlling heating temperature. For example, the heating element 20 uses a magnetic material, which helps to guide the thermal field, improve thermal efficiency, reduce energy loss, and ensure that the heated air can be effectively introduced into the heat dissipation shell 10, thereby improving the utilization rate of hot air. It should also be noted that a gap is set between the coil module 50 and the heating element 20. Under the effect of the gap, the high temperature of the heating element 20 can reduce the temperature influence of the environment where the coil module 50 is located, improve the safety of use, and also help protect the coil module 50 and extend its service life. Furthermore, the heating element 20 is located adjacent to the coil module 50 and is heated by the coil module 50. Its specific shape design should facilitate uniform airflow distribution and efficient heat exchange. The impeller 30 is located within the heating element 20; its rotation generates a powerful airflow, which is heated as it passes through the heated heating element 20 and ultimately exhausted from the front of the fan head.

[0055] The coil cover 40 can be used as the outermost housing 10 of the entire air conditioning equipment, or it can be an independent intermediate housing 10.

[0056] Specifically, the corresponding arrangement between the coil module 50 and the heating element 20 is such that the electromagnetic coil 52 generates a magnetic field that surrounds the magnetically conductive heating element 20. By using electromagnetic heating, eddy currents are generated on the heating element 20, thus effectively heating it. Furthermore, without affecting the heating effect, the greater the distance between the coil module 50 and the heating element 20, the less heat is conducted from the heating element 20 to the coil module 50.

[0057] It should be emphasized that a heat dissipation channel 13 for cooling the electromagnetic coil 52 is provided inside the housing 10. Due to the structural characteristics of the coil cover 40, air can flow in and out. The coil module 50 generates a lot of heat during operation. By setting the coil cover 40, a heat dissipation channel 13 is formed between it and the heat-generating body 20. When the air flows, it can carry away the heat of the coil module 50, thereby effectively solving the temperature rise problem of the coil module 50.

[0058] Optionally, the air conditioning device 100 also includes a motor 70, the drive shaft of which passes through the impeller 30 and is used to drive the impeller 30 to rotate.

[0059] In this technical solution, the motor 70 drives the operation of the fan wheel 30, so that the air flows directly out after being heated by the heating element 20 in the airflow path. By using the motor 70, the overall automation and intelligence of the device can be effectively improved. At the same time, the operating speed of the air conditioning equipment can be controlled by controlling the motor 70.

[0060] It should be added that the type of motor 70 can be a DC or AC motor 70, or even a brushless motor 70 to improve efficiency and reduce maintenance; the power and speed of the motor 70 must be matched with the design of the impeller 30; and the heat dissipation design of the motor 70 must ensure that it will not overheat during long-term operation.

[0061] It is understandable that the air conditioning equipment 100 mainly converts electrical energy into heat and mechanical energy to generate hot air. In this solution, by adjusting the relative positions of the motor 70 and the impeller 30, and by adding a structure to the heating element 20, air is blown towards the heating element 20 under the action of the impeller 30. The heating element 20 is heated by the coil module 50, which can increase the temperature of the air blown towards the heating element 20. At the same time, the structural features of the heating element 20 itself can guide the air to the outside of the air conditioning equipment, thereby providing warm air with a higher wind speed.

[0062] Optionally, the coil module 50 specifically includes a heating bracket 51, which is correspondingly arranged with the heating element 20 and located outside the heating element 20. An electromagnetic coil 52 is wound on the heating bracket 51, which helps to ensure effective cooperation between the heating bracket 51 and the heating element 20 and provides a stable support structure. In addition, the heating bracket 51 can be disc-shaped, i.e., in the form of a coil disc, which can be adapted to cooperate with the coil cover 40 to jointly form a heat dissipation section 132 for dissipating heat from the electromagnetic coil 52. By winding the electromagnetic coil 52 on the coil disc, an alternating magnetic field is generated after the electromagnetic coil 52 is energized, enabling the heating element 20 to achieve electromagnetic induction heating, providing an efficient way for air heating.

[0063] Optionally, the air handling unit 100 further includes: a heat insulation bracket disposed on the outside of the heating element 20, a coil cover 40 disposed on the outside of the heat insulation bracket, and a coil module 50 disposed between the heat insulation bracket and the coil cover 40.

[0064] In this technical solution, the heat insulation bracket is fixed to the coil disc (or heating bracket 51). Specifically, the coil disc is positioned on the outside of the heat insulation bracket, and also on the outside of the heating element 20. The heat insulation bracket can isolate the heating element 20 and the coil module 50 to a certain extent, reducing heat conduction to the heating element 20, thereby lowering the temperature of the heating element 20 and improving safety. Furthermore, the heat insulation bracket can also be fixed to the heating element 20, providing additional support and stability, helping to maintain the positional stability of the heating element 20, reducing vibration and friction, and improving the reliability of the entire system.

[0065] In this design, the heating element 20 can be an independent heating structure, or it can be a structure that includes both a heat insulation bracket and the heating element 20.

[0066] It is understandable that the corresponding arrangement between the electromagnetic coil 52 and the heating element 20 is such that the electromagnetic coil 52 can generate a magnetic field that surrounds the heating element 20, which is made of magnetically conductive material. By using electromagnetic heating, eddy currents are generated on the heating element 20, thereby effectively heating the heating element 20. In addition, without affecting the heating effect, the greater the distance between the electromagnetic coil 52 and the heating element 20, the less heat is conducted from the heating element 20 to the electromagnetic coil 52.

[0067] 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.

[0068] Assembly Method 1: The electromagnetic coil 52 is installed on the coil module 50, and the heating element 20 is fixedly connected to the coil module 50. The coil cover 40 is placed on the outside of the coil module 50. The impeller 30 can be positioned in the center area of ​​the heating element 20 by hand, thereby realizing the modular assembly of the heating element 20, the coil cover 40, the coil module 50 and the impeller 30. Then, the above components are placed into the housing 10, and the coil module 50, the coil cover 40 and the impeller 30 are further connected to the housing 10. Finally, the air inlet screen 11 is installed at the air inlet 101 of the housing 10 to complete the assembly of the air handling equipment 100.

[0069] Assembly Method 2: First, the heating element 20 is fixedly installed inside the housing 10. Then, the coil module 50, which is equipped with the electromagnetic coil 52, is fitted on the radial outer side of the heating element 20, and the coil bracket 51 is fixedly connected to the housing 10. Then, the coil cover 40 can be placed on the outside of the coil module 50 and fixedly connected to the housing 10. Next, the impeller 30 is positioned and installed in the central area of ​​the heating element 20, and the air inlet mesh cover 11 is installed at the air inlet 101 of the housing 10 to complete the assembly of the air handling equipment 100.

[0070] 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.

[0071] According to the present invention, the heater 1000 includes the aforementioned air handling device 100. By setting the aforementioned air handling device 100 in the heater 1000, the heat dissipation effect on the electromagnetic components can be improved, thereby improving operational safety and increasing the outlet air temperature.

[0072] Combination Figure 5 In some embodiments of this utility model, the heater 1000 includes a bracket 200, and the air handling unit 100 is swayably mounted on the bracket 200, for example, it can be mounted on the top of the bracket 200. When in use, the air handling unit 100 can sway to adjust the air outlet direction, providing convenience for the user.

[0073] Furthermore, the heater 1000 may also include a drive unit 300 for driving the air handling equipment 100 to oscillate.

[0074] Optionally, the heater 1000 may also include a base that is detachably connected to the air conditioning unit 1000. This design facilitates the assembly and disassembly of the unit, making it more flexible, easier to move, and easier to maintain. The base provides stable support, helping to maintain the stability of the entire heater 1000, reducing shaking and swaying during operation, and improving the safety and reliability of the unit.

[0075] Furthermore, since the base is detachably connected to the air conditioning equipment, different air conditioning equipment can be selected as needed, making the heater 1000 more widely applicable and flexible. The drive unit 300 can be mounted on the base.

[0076] In some embodiments, when the heater 1000 is actually in use, the air inlet 101 is located on the rear side of the housing 10, and the air outlet 102 is located on the front side of the housing 10. That is, the heater 1000 takes in air from the rear side and outputs airflow forward.

[0077] In some embodiments of this utility model, the heater 1000 has a cold air operation mode and a warm air operation mode. The control method further includes determining the operation mode of the heater, thereby setting the heater to operate in cold air mode or warm air mode according to the user's selection, ensuring that the heater 1000 can provide suitable air output according to the user's usage needs, which is beneficial to improving the functionality of the heater.

[0078] Based on this, the operating mode of the heater 1000 can be controlled by controlling the operating status of the fan wheel 30 and the heating element 20. When the heater 1000 is in the cold air operating mode, the fan wheel 30 can be started to generate cold air, while the heating element 20 does not work, so as to ensure that the heater 1000 can provide pure cold air, so that the heater 1000 can be used to cool down the environment with high temperature, and at the same time, it helps to reduce the energy consumption of the heater 1000.

[0079] It should be noted that when the heater 1000 is started and selected to run in cold air mode, there is no action to stop the heating element 20. However, if the heater 1000 switches from warm air mode to cold air mode, there is an action to stop the heating element 20.

[0080] When the heater 1000 is in the warm air operation mode, the fan wheel 30 and the heating element 20 work simultaneously to ensure that the heater 1000 can output hot air, so that the heater 1000 can be used to heat the environment with low temperature.

[0081] In some embodiments, the cold air operation mode of the heater 1000 needs to ensure that the output air speed of the heater 1000 is high enough. That is, the number of speed settings in the cold air operation mode of the heater 1000 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 1000 can have 8 speed settings in the cold air operation mode and 3 speed settings in the warm air operation mode. When the heater 1000 switches directly from the 3rd speed setting in the cold air mode to the warm air mode, the heater 1000 operates at the maximum speed setting (i.e., the third speed setting) in the warm air mode, and the output heat of the heater 1000 is most efficient.
