[0045] In related technologies, air conditioning equipment can regulate air temperature. In some existing technologies, air conditioning equipment is equipped with heating components and air guiding components. The heating components have a large resistance to airflow, which causes the airflow speed to decrease after passing through the heating components, resulting in low air outlet speed of the air conditioning equipment and resistance loss.

[0046] The following is for reference. Figures 2-6 Description of a heating assembly 10 for an air conditioning device according to an embodiment of the present invention.

[0047] like Figures 2-6 As shown, the heating assembly 10 for an air conditioning device according to this utility model includes: a flow guide bracket 11 and a heating element 12. The flow guide bracket 11 has a flow guide surface 111 extending from the airflow inlet 41 to the airflow outlet 42, and the flow guide surface 111 is provided with a mounting portion 1111. The heating element 12 is disposed on the mounting portion 1111 and is used to heat the flow guide bracket 11 so that the heating assembly 10 is suitable for heating the airflow passing through it. Specifically, the air conditioning device 1 generally has an airflow inlet 41 and an airflow outlet 42. The heating element 12 is disposed on the flow guide bracket 11. After the heating element 12 is energized, it can conduct heat to the flow guide bracket 11. When the airflow passes through the flow guide bracket 11, it can carry away the heat on the flow guide bracket 11 and / or the heating element 12. At the same time, the flow guide surface 111 formed by the flow guide bracket 11 can guide the airflow from the airflow inlet 41 to the airflow outlet 42. That is to say, the heating assembly 10 has the functions of heating the airflow and guiding the airflow direction.

[0048] The heating component 10 for air conditioning equipment according to this utility model integrates heating and airflow guiding functions, which can reduce the number of parts in the air conditioning equipment 1 and reduce airflow resistance, thereby reducing resistance loss during airflow and improving the air outlet performance of the air conditioning equipment 1, thus enhancing the user experience.

[0049] In some embodiments, the flow guide bracket 11 is a metal bracket. When the heating element 12 heats the metal bracket, the heat conduction effect of the metal bracket is better, and the heating effect of the airflow is also better.

[0050] According to some embodiments of this utility model, such as Figure 4 As shown, the airflow guide bracket 11 is constructed as an annular bracket, and an airflow guide surface 111 is formed on the inner surface of the annular bracket. Specifically, the two sides of the annular bracket in the axial direction are open to form a first opening and a second opening, wherein the first opening is connected to the airflow inlet 41 of the air conditioning device 1, and the second opening is connected to the airflow outlet 42 of the air conditioning device 1. The airflow guide surface 111 located on the inner side of the annular bracket conducts the first opening and the second opening to facilitate the airflow between the airflow inlet 41 and the airflow outlet 42.

[0051] According to some embodiments of this utility model, such as Figure 4 As shown, the heating element 12 is constructed as a heating plate extending along the inner or outer peripheral wall of the airflow guide 11. Specifically, the heating element 12 can be disposed on the inner peripheral wall of the airflow guide 11, in which case the heating element 12 is positioned on the side of the airflow guide 11 facing the airflow; or the heating element 12 can be disposed on the outer peripheral wall of the airflow guide 11, in which case the heating element 12 is positioned on the side of the airflow guide 11 away from the airflow. The position of the heating element 12 is not limited, as long as the heating element 12 can transfer heat to the airflow guide 11. Here, the heating element 12 is constructed as a heating plate, which is relatively thin and occupies less space, facilitating the arrangement of other structures in the air conditioning device 1.

[0052] In some embodiments, the heating element 12 extends circumferentially and / or axially in the flow guide bracket 11 to fully heat the flow guide bracket 11.

[0053] According to some embodiments of this utility model, such as Figure 4 As shown, at least a portion of the mounting portion 1111 protrudes from the inner peripheral wall of the flow guide bracket 11, and at least a portion of the heating element is housed within the mounting portion 1111. Here, the mounting portion 1111 can be located on the inner side of the flow guide bracket 11 in the radial direction, which can reduce the space occupied by the heating assembly 10 in the radial direction.

[0054] According to some embodiments of this utility model, such as Figure 5As shown, the mounting part 1111 is constructed as a groove 1112 formed by the outer peripheral wall of the flow guide bracket 11 concave to the inner peripheral wall of the flow guide bracket 11. The outer peripheral wall of the flow guide bracket 11 has a mounting opening 1113 communicating with the groove 1112. The heating element is embedded in the groove 1112 through the mounting opening 1113. In some embodiments, the groove 1112 formed by the outer peripheral wall of the flow guide bracket 11 concave to the inner peripheral wall of the flow guide bracket 11 can be formed by stamping. In this case, the mounting opening 1113 communicating with the groove 1112 is formed on the side of the groove 1112 facing the outer peripheral wall of the flow guide bracket 11. At least part of the heating element is embedded in the groove 1112 through the mounting opening 1113, which facilitates the installation of the heating element.

[0055] In addition, the heating element can be fixedly connected to the flow guide bracket 11, or it can be detachably connected to the flow guide bracket 11.

[0056] According to some embodiments of the present invention, the heating assembly 10 for an air conditioning device further includes an adhesive layer, which is disposed between the bottom of the heating element and the bottom wall of the groove 1112. At this time, the heating element is bonded to the groove 1112 on the flow guide bracket 11, which facilitates the operation of assembling the heating element to the flow guide bracket 11, improves the assembly efficiency of the heating assembly 10, and reduces the assembly difficulty of the heating assembly 10.

[0057] According to some embodiments of this utility model, such as Figure 4 As shown, the mounting portion 1111 is configured as a plurality of portions spaced axially and / or circumferentially on the inner wall of the flow guide bracket 11. The heating element 12 can also be configured as a plurality of portions. At least some of the mounting portions 1111 are provided with heating elements 12. The plurality of mounting portions 1111 are spaced axially and / or circumferentially on the flow guide bracket 11, so that the plurality of heating elements 12 can be spaced axially and / or circumferentially on the flow guide bracket 11 to heat various parts of the flow guide bracket 11, so that the flow guide bracket 11 can fully and uniformly heat the airflow passing through it, thereby improving the uniformity of the outlet air temperature of the air conditioning equipment 1.

[0058] According to some embodiments of this utility model, such as Figures 4-6 As shown, the length of the groove 1112 in the extension direction of the guide surface 111 is Lc, and the length of the heating element in the extension direction of the guide surface 111 is Lt, satisfying: Lc ≥ Lt + 4mm. Here, to facilitate the assembly operation of the heating element and the groove 1112 and to allow the heating element and the groove 1112 to fit better, a gap can be reserved between the groove 1112 and the heating element in the extension direction of the guide surface 111, that is, Lc ≥ Lt + 4mm. In some embodiments, a gap of 2mm can be reserved on both sides of the groove 1112 and the heating element in the extension direction of the guide surface 111, to facilitate the assembly operation of the heating element and the groove 1112 and to allow the heating element and the groove 1112 to fit better.

[0059] According to some embodiments of this utility model, such as Figures 4-6 As shown, the width of the groove 1112 in the circumferential direction of the flow guide bracket 11 is Wc, and the width of the heating element in the circumferential direction of the flow guide bracket 11 is Wt, satisfying: Wc ≥ Wt + 4mm. Here, to facilitate the assembly operation of the heating element and the groove 1112 and to ensure a better fit between them, a gap can be reserved between the groove 1112 and the heating element in the circumferential direction of the flow guide bracket 11, that is, Wc ≥ Wt + 4mm. In some embodiments, gaps can be reserved on both sides of the groove 1112 and the heating element in the circumferential direction of the flow guide bracket 11, with a gap of 2mm on each side, to facilitate the assembly operation of the heating element and the groove 1112 and to ensure a better fit between them.

[0060] According to some embodiments of this utility model, such as Figures 4-6 As shown, the depth dimension of the groove 1112 in the radial direction of the flow guide bracket 11 is Hc, and satisfies: Hc≤5mm. It can be understood that since the mounting part 1111 is constructed as a groove 1112 that is recessed from the outer peripheral wall of the flow guide bracket 11 to the inner peripheral wall of the flow guide bracket 11, if the depth of the groove 1112 is too large, it will affect the structural strength of the flow guide bracket 11 and increase the wind resistance of the flow guide bracket 11 to the airflow. If the depth of the groove 1112 is too small, it will be difficult to install the heating element. Therefore, optionally, the depth dimension of the groove 1112 in the radial direction of the flow guide bracket 11 is Hc≤5mm, so as to avoid increasing the wind resistance of the flow guide bracket 11 to the airflow.

[0061] According to some embodiments of this utility model, such as Figure 4 As shown, the inner diameter of the flow guide 11 gradually increases in the airflow direction. In some embodiments, the projection of the first opening of the flow guide 11 in the axial direction is located within the projection of the second opening in the axial direction. In this case, the flow guide 11 is constructed as a trumpet shape with a large opening on one side and a small opening on the other side, so as to guide the airflow from the smaller first opening to the larger second opening, thereby expanding the airflow range.

[0062] Here, the heating element can be installed inside the flow guide bracket 11 itself, or it can be set on the surface of the flow guide bracket 11. The heating element can be set on the inner surface of the flow guide bracket 11, or it can be set on the outer surface of the flow guide bracket 11.

[0063] According to some embodiments of the present invention, at least a portion of the flow guide bracket 11 is bent to define a groove. Here, the groove provided on the flow guide bracket 11 can increase the contact area between the flow guide bracket 11 and the airflow, thereby improving the heat exchange effect between the airflow and the flow guide bracket 11.

[0064] According to some embodiments of this utility model, the groove extends along the axial direction of the flow guide bracket 11 to increase the heat dissipation area between the airflow and the flow guide bracket 11 in the axial direction, thereby improving the heat exchange effect between the airflow and the flow guide bracket 11. Furthermore, the groove can also guide the airflow along the flow guide bracket 11, further improving the heat dissipation effect.

[0065] Here, the groove extends along the axial direction of the flow guide 11. This can mean that the extension direction of the groove is parallel to the axial direction of the flow guide 11; or it can mean that the extension direction of the groove intersects with the axial direction of the flow guide 11. In this case, the groove extends obliquely along the axial direction of the flow guide 11. The extension direction of the groove is sufficient to guide the airflow to flow along the axial direction of the flow guide 11. Its specific extension direction can be designed according to actual needs.

[0066] In some embodiments, there are multiple grooves, which are arranged circumferentially along the guide bracket 11.

[0067] According to some embodiments of this utility model, the heating element is constructed as a PTC heating element, which can achieve self-temperature control after being powered on, and has high safety.

[0068] The following is a brief description of the air conditioning device 1 according to this utility model.

[0069] like Figure 2 , Figure 3 As shown, the air conditioning device 1 according to this utility model includes: a heating component 10 and a fan 20. The heating component 10 is constructed as described in any of the above embodiments for an air conditioning device. At least a portion of the fan 20 is located within a guide bracket 11. Here, the fan 20 is adapted to drive airflow from the airflow inlet 41 towards the airflow outlet 42. A portion of the fan 20 can be disposed within the guide bracket 11 of the heating component 10 and adapted to dissipate heat from the guide bracket 11. Another portion of the fan 20 can be located outside the guide bracket 11. This portion of the fan 20 can discharge air towards the heating element 12 to dissipate heat from the heating element 12. Alternatively, this portion of the fan 20 can also discharge air towards other structures of the air conditioning device 1 to dissipate heat from other structures of the air conditioning device 1, thereby optimizing the heat dissipation effect of the fan 20 on the heating component 10 and other structures of the air conditioning device 1. Because the air conditioning device 1 according to this utility model is equipped with the heating component 10 of the above embodiments, the air conditioning device 1 has a better airflow effect and a better user experience.

[0070] According to some embodiments of this utility model, such as Figure 2 , Figure 3As shown, the air conditioning device 1 also includes a housing 40, inside which an installation space is formed. The housing 40 also has an airflow inlet 41 and an airflow outlet 42, which are respectively connected to the installation space. The installation space is suitable for installing the heating element 10 and the impeller 20. Here, the housing 40 also has an airflow inlet 41 and an airflow outlet 42. The installation space can connect the airflow inlet 41 and the airflow outlet 42. External air enters the installation space through the airflow inlet 41 and further flows out of the installation space through the airflow outlet 42. The heating element 10 and the impeller 20 of the air conditioning device 1 are disposed within the installation space to heat the airflow flowing through the installation space, enabling the air conditioning device 1 to output hot air.

[0071] In some embodiments, the air conditioning device 1 further includes a drive component 50, which is connected to the impeller 20 and adapted to drive the impeller 20 to rotate, so that the impeller 20 can drive airflow. The housing 40 can provide positioning support for structures such as the drive component 50, the impeller 20, and the heating component 10, ensuring the overall stability of the air conditioning device 1. Furthermore, since the drive component 50, the impeller 20, and the heating component 10 are housed within the housing 40, the risk of interference between these structures and external structures is reduced through the protection of the housing 40, thereby reducing the risk of damage to the air conditioning device 1 and extending its service life.

[0072] According to some embodiments of this utility model, such as Figure 4 As shown, the flow guide bracket 11 has a mounting hole 1114 on one side of the axial direction, which is suitable for detachable connection with the inner wall of the installation space. The flow guide bracket 11 can be detachably connected to the housing 40 through the mounting hole 1114. By installing the flow guide bracket 11 onto the housing 40, the heating component 10 can be installed on the housing 40 as a whole, realizing modular installation.

[0073] In some embodiments, a flow guide 30 is provided on the side of the heating assembly 10 away from the impeller 20 to further guide the airflow direction, and the inner diameter of the flow guide 30 gradually increases in the airflow direction.

[0074] According to some embodiments of this utility model, the impeller 20 is a centrifugal impeller, which is adapted to guide at least a portion of the airflow to the heating component 10. Here, the air inlet and outlet directions of the centrifugal impeller are mainly axial air inlet and radial air outlet. The guide bracket 11 can be set on the outer side of at least a portion of the centrifugal impeller in the radial direction to realize the arrangement of the heating component 10 on the air outlet side of the impeller 20, so that the air flowing out of the impeller 20 can flow through the heating component 10, thereby facilitating the heat dissipation of the heating component 10.

[0075] The following is a simple description of the assembly method of air conditioning equipment 1.

[0076] Assembly Method 1: The impeller 20 can be positioned in the center of the guide bracket 11 by hand, and the guide cover can be put on the outside of the guide bracket 11, thereby realizing the modular assembly of the heating component 10, the guide cover 30 and the impeller 20. Then, the above components are put into the housing 40 and further fixedly connected to the housing 40, so that the impeller 20 is connected to the housing 40. Finally, the housing 40 is sealed to complete the assembly of the air conditioning device 1.

[0077] In order to ensure the assembly reliability of the components inside the housing 40 with the housing 40, the mounting bracket 41 can be further connected to the housing 40 to reduce the risk of the structural components inside the housing 40 falling off the housing 40.

[0078] Assembly method 2: First, the heating component 10 is fixedly installed inside the housing 40. Then, the flow guide is fitted on the radial outer side of the heating component 10 and fixedly connected to the housing 40. Next, the flow guide bracket 11 is fixedly connected to the housing 40. Then, the impeller 20 is positioned in the central area of ​​the heating component 10 and connected to the housing 40. Finally, the housing 40 is sealed to complete the assembly of the air conditioning equipment 1.

[0079] 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 conditioning equipment 1. Of course, it is understood that the fixed connection method includes, but is not limited to, connecting by threaded connectors, or by snap-fit, etc. The specific fixed connection method can be determined according to the actual production requirements, and is not specifically limited here.

[0080] In the air conditioning device 1 designed according to this application, the airflow outside the air conditioning device 1 enters the interior of the housing 40 through the air inlet on the housing 40, and the airflow flows radially toward the airflow outlet 42 under the drive of the centrifugal impeller 20.

[0081] The following is a brief description of the heater 1000 according to this utility model.

[0082] The heater 1000 according to this utility model includes the air conditioning device 1 described in any of the above embodiments. Because the heater 1000 according to this utility model is equipped with the air conditioning device 1 of the above embodiments, the user experience of the heater 1000 is better.

[0083] In some embodiments, such as Figure 1As shown, the heater 1000 also includes a bracket 2, on which the air conditioning device 1 is rotatably mounted. Specifically, the bracket 2 serves as a mounting carrier for the air conditioning device 1, supporting it. By rotatably mounting the air conditioning device 1 on the bracket 2, the air outlet direction of the heater 1000 can be adjusted, which helps improve the heating effect and heating uniformity of the heater 1000, thereby enhancing the user experience.

[0084] In some embodiments, the bracket 2 of the heater 1000 is rotatably connected to the base of the heater 1000. The base of the heater 1000 is provided with a drive unit for driving the bracket 2 to swing in the left-right direction. The bracket 2 of the heater 1000 forms an installation space, and the inner wall of the installation space is provided with a connecting part. The air conditioning device 1 is rotatably connected to the connecting part and accommodated in the installation space. For example, the connecting part of the bracket 2 of the heater 1000 clamps the air conditioning device 1 in the left-right direction and drives the air conditioning device 1 to swing up and down. Optionally, the up-and-down swing of the air conditioning device 1 can also be in the form of a guide rail. Alternatively, the bracket 2 of the heater 1000 can be disposed on the base of the heater 1000, and the drive unit can be disposed on the bracket 2 of the heater 1000 and connected to the air conditioning device 1 to drive the air conditioning device 1 to swing up and down or left and right.

[0085] In some embodiments, the heater 1000 has a cold air operation mode and a warm air operation mode. The user can choose whether to operate in cold air mode or warm air mode to ensure that the heater can provide appropriate air output according to the user's needs, which helps to improve the functionality of the heater.

[0086] Based on this, the operating mode of the heater 1000 can be controlled by controlling the operating status of the fan wheel 20 and the heating component 10. When the heater 1000 is in the cold air operating mode, the fan wheel 20 can be started to generate cold air, while the heating component 10 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.

[0087] 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 component 10. However, if the heater 1000 switches from warm air mode to cold air mode, there is an action to stop the heating component 10.

[0088] When the heater 1000 is in the warm air operation mode, the fan 20 and the heating element 10 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.

[0089] 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.

[0090] In summary, the heating component 10 for air conditioning equipment designed according to this utility model has the functions of heating airflow and guiding airflow direction. It can reduce the number of parts in the air conditioning equipment 1, reduce airflow resistance, reduce resistance loss during airflow, improve the air outlet effect of the air conditioning equipment 1, and thus improve the user experience.
