Compared with setting multiple first reinforcing members on both sides of the electric auxiliary heating assembly in the windward width direction, this application can reduce the size occupied by the electric auxiliary heating structure in the windward width direction, and the electric auxiliary heating structure as a whole can also have better structural strength, which facilitates the miniaturization design of the electric auxiliary heating structure.

[0006] In some embodiments, the first reinforcing member includes a first plate and a second plate, the first plate being fixedly connected to the electric auxiliary heating assembly, and the second plate being bent and connected to the side of the first plate away from the electric auxiliary heating assembly.

[0045] 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0047] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0048] Hereinafter, with reference to the accompanying drawings, an electric auxiliary heating structure 100 according to a first aspect embodiment of the present invention will be described.

[0049] Please refer to Figure 1 and Figure 2 The electric auxiliary heating structure 100 includes an electric auxiliary heating component 1, a first reinforcing member 2, and at least one second reinforcing member 3. The electric auxiliary heating component 1 has a windward surface 11 extending along its length direction. The first reinforcing member 2 extends along the length direction of the electric auxiliary heating component 1 and is fixed to one side of the electric auxiliary heating component 1 on the width direction of the windward surface 11. The second reinforcing member 3 is formed into a ring structure and is clamped to the outer periphery of the electric auxiliary heating component 1 and the first reinforcing member 2. Exemplarily, the length direction of the electric auxiliary heating structure 100, the length direction of the first reinforcing member 2, and the length direction of the windward surface 11 are consistent, and all three are horizontal. The upper end face of the electric auxiliary heating structure 100 is the windward surface 11.

[0050] As can be seen, the first reinforcing member 2 is fixed to the electric auxiliary heating assembly 1 and extends along the length of the electric auxiliary heating assembly 1, so that the first reinforcing member 2 provides structural reinforcement to the electric auxiliary heating assembly 1, making it less prone to bending deformation during use. The first reinforcing member 2 is fixed to one side of the electric auxiliary heating assembly 1 on the windward side 11. The first reinforcing member 2 improves the bending resistance of the electric auxiliary heating assembly 1, and it is less likely to obstruct the airflow towards the windward side 11, thus not affecting the heating capacity of the electric auxiliary heating assembly 1 and improving the reliability of the electric auxiliary heating structure 100. For example, the electric auxiliary heating structure 100 is used in an air conditioner 200, which includes a heat exchanger structure 6. The electric auxiliary heating structure 100 is fixed to the heat exchanger structure 6, and at least a portion of the heat exchanger structure 6 is located upstream of the electric auxiliary heating structure 100. Thus, at least a portion of the heat exchanger structure 6 is located upstream of the windward surface 11. Through the arrangement of the first reinforcing member 2, the first reinforcing member 2 is less likely to affect the airflow to the electric auxiliary heating component 1 and less likely to affect the heating effect of the air conditioner 200.

[0051] Furthermore, the second reinforcing member 3 is annular and is clamped around the outer periphery of the electric auxiliary heating assembly 1 and the first reinforcing member 2. For example, the inner peripheral wall of the second reinforcing member 3 can provide a certain constraint and fastening effect on the electric auxiliary heating assembly 1 and the first reinforcing member 2, so that the electric auxiliary heating assembly 1 is less prone to torsional deformation, and the electric auxiliary heating assembly 1 and the first reinforcing member 2 fit together more stably, thereby improving the overall structural strength of the electric auxiliary heating structure 100. This helps to reduce the deformation of the electric auxiliary heating structure 100 during use and drop tests, so that when the electric auxiliary heating structure 100 is used in electrical appliances such as air conditioners 200, This facilitates the drop test of the air conditioner 200; at the same time, even if the electric auxiliary heating structure 100 collides with other components, by setting the second reinforcing member 3 around the outer periphery of the first reinforcing member 2 and the electric auxiliary heating component 1, under certain conditions, when a collision occurs, the second reinforcing member 3 can collide with other components first, and the first reinforcing member 2 and the electric auxiliary heating component 1 may not directly collide with other components, so that the cooperation between the electric auxiliary heating component 1 and the first reinforcing member 2 is not easy to detach, and the first reinforcing member 2 can still play a certain role in reinforcing the electric auxiliary heating component 1, which facilitates the drop test of the air conditioner 200, etc.

[0052] It should be noted that the term "ring" in this application is to be interpreted broadly, that is, not limited to "circular ring", but can also be "polygonal ring", etc.; in addition, "ring" includes open rings (i.e. non-closed rings, such as C-shaped, U-shaped, Ω-shaped, etc.) and closed rings.

[0053] For example, the electric auxiliary heating structure 100 is used in an air conditioner 200, which includes a heat exchanger structure 6 and a fan. The fan is located downstream of the heat exchanger structure 6, and the electric auxiliary heating structure 100 is fixed on the heat exchanger structure 6 and located between the heat exchanger structure 6 and the fan in the airflow direction. The airflow can flow through the heat exchanger structure 6, the electric auxiliary heating structure 100 and the fan in sequence. When the air conditioner 200 is subjected to external impact or vibration, the electric auxiliary heating structure 100 may collide with the heat exchanger structure 6 and / or the fan, especially when the electric auxiliary heating component 1 is long. This application can improve the overall structural strength of the electric auxiliary heating structure 100 by setting the first reinforcing member 2 and the second reinforcing member 3, which is conducive to improving the reliability of the electric auxiliary heating structure 100 and reducing the drop deformation of the electric auxiliary heating structure 100, so as to improve the performance of the electric auxiliary heating structure 100 in drop tests or accidental drops.

[0054] For example, the electric auxiliary heating structure 100 may include a plurality of second reinforcing members 3, which are spaced apart along the length direction of the electric auxiliary heating assembly 1 to further improve the overall structural strength of the electric auxiliary heating structure 100. For example, the electric auxiliary heating structure 100 includes two second reinforcing members 3, one of which is disposed adjacent to one end of the length of the electric auxiliary heating assembly 1, and the other is disposed adjacent to the other end of the length of the electric auxiliary heating assembly 1.

[0055] Compared to some technologies where the electric auxiliary heating assembly (e.g., the PCT body) has a certain length, making it prone to deformation and impact with other components during drop tests, it is common practice to install first reinforcing members on both sides of the width of the electric auxiliary heating assembly. Each first reinforcing member has a U-shaped cross-section to maximize the space occupied by the electric auxiliary heating structure in the width direction of the windward side. When used in air conditioners, the electric auxiliary heating assembly typically works in conjunction with the heat exchanger, resulting in a correspondingly larger heat exchanger and consequently, a larger overall air conditioner size. However, this application addresses this by placing the first reinforcing member 2 on one side of the width of the windward side 11, thereby reducing the space required for the electric auxiliary heating assembly 1 while maintaining the same size. The dimensions and space occupied by the auxiliary heating structure 100 in the width direction of the windward side 11 facilitate the miniaturization design of the electric auxiliary heating structure 100. The second reinforcing member 3 is provided and clamped around the outer periphery of the electric auxiliary heating component 1 and the first reinforcing member 2, so that the electric auxiliary heating structure 100 has good structural strength, is not prone to deformation, and does not impose too many restrictions on the cross-sectional shape of the first reinforcing member 2. The requirements for the cross-sectional shape of the first reinforcing member 2 are not too high, and the arrangement of the first reinforcing member 2 is not changed to save space, which would weaken the structural strength of the electric auxiliary heating structure 100. Thus, it is easy to simultaneously take into account the overall structural strength and overall structural size of the electric auxiliary heating structure 100.

[0056] For example, when the electric auxiliary heating structure 100 is used in a wall-mounted air conditioner, the wall-mounted air conditioner includes a heat exchanger structure 6, and the electric auxiliary heating structure 100 is fixed to the heat exchanger structure 6. The electric auxiliary heating structure 100 of this application occupies a small overall space, so that the heat exchanger structure 6 does not need to make room for the arrangement of the electric auxiliary heating structure 100, which can reduce the size of the heat exchanger structure 6, thereby reducing the overall size of the wall-mounted air conditioner, which is conducive to the miniaturization design of the wall-mounted air conditioner.

[0057] According to the electric auxiliary heating structure 100 of this utility model embodiment, the first reinforcing member 2 is fixedly disposed on one side of the electric auxiliary heating component 1 in the width direction of the windward surface 11, and the second reinforcing member 3 is clamped on the outer periphery of the electric auxiliary heating component 1 and the first reinforcing member 2, so as to improve the overall structural strength of the electric auxiliary heating structure 100 and prevent large deformation. Compared with the electric auxiliary heating component having the first reinforcing member disposed on both sides in the width direction of the windward surface, this application is beneficial to reducing the size occupied by the electric auxiliary heating structure 100 in the width direction of the windward surface 11, and the electric auxiliary heating structure 100 as a whole has better structural strength, which facilitates the miniaturization design of the electric auxiliary heating structure 100.

[0058] Please refer to Figure 1 and Figure 2 In some embodiments, the first reinforcing member 2 includes a first plate 21 and a second plate 22. The first plate 21 is fixedly connected to the electric auxiliary heating assembly 1, and the second plate 22 is bent and connected to the side of the first plate 21 away from the electric auxiliary heating assembly 1. For example, the cross-sectional shape of the first reinforcing member 2 can be configured as an "L", "├" (or T), or U-shaped, so that the first reinforcing member 2 and the electric auxiliary heating assembly 1 can be matched to improve the overall bending resistance of the first reinforcing member 2 and the electric auxiliary heating assembly 1, thereby improving the reliability of the electric auxiliary heating structure 100. The structure of the first reinforcing member 2 is relatively simple and easy to manufacture. Alternatively, there can be one or more second plates 22. Moreover, by setting the second plate 22, an installation platform can be provided for the arrangement of other components. For example, the second reinforcing member 3 can be fixedly connected to the second plate 22 by the third fastener 42 or the fourth fastener 43 described later, without having to be directly fixed to the electric auxiliary heating assembly 1, thus facilitating the assembly of the electric auxiliary heating structure 100.

[0059] Please refer to Figure 1 and Figure 2 In some embodiments, the first plate 21 is fixed to the electric auxiliary heating assembly 1 by a first fastener 41, and a second plate 22 is connected to both sides of the width of the first plate 21. The two second plates 22 are spaced apart to define a first through-hole 23 for the first fastener 41 to pass through. For example, the cross-sectional shape of the first reinforcing member 2 is U-shaped, which has a relatively simple structure and is easy to process and manufacture.

[0060] As can be seen, by connecting the second plates 22 to both ends of the width of the first plate 21, the first reinforcing member 2 can have better structural strength, thereby improving the overall bending resistance of the first reinforcing member 2 and the electric auxiliary heating assembly 1, and facilitating the improvement of the reliability of the electric auxiliary heating structure 100. The two second plates 22 are spaced apart to define the first through-hole 23, providing space for the first fastener 41 to pass through. The assembly of the first fastener 41 is less likely to interfere with the second plates 22, thus reducing the assembly difficulty of the first reinforcing member 2 and the electric auxiliary heating assembly 1 and improving assembly efficiency.

[0061] For example, the first fastener 41 is a threaded fastener (such as a screw), which passes through the first plate 21 and is threaded to the electric auxiliary heating assembly 1.

[0062] Of course, in other embodiments of this application, the first reinforcing member 2 may also be configured to include the first plate 21 but not the second plate 22.

[0063] Please refer to Figures 3-5 In some embodiments, the electric auxiliary heating assembly 1 has a square cross-sectional shape, and the first reinforcing member 2 is flush with the corresponding surfaces of the electric auxiliary heating assembly 1 at both ends in the direction perpendicular to the windward surface 11. For example, the windward surface 11 is the upper surface of the electric auxiliary heating assembly 1, and the upper and lower surfaces of the electric auxiliary heating assembly 1 and the upper and lower surfaces of the first reinforcing member 2 are respectively flush. Therefore, in the vertical direction, the first reinforcing member 2 does not extend beyond the upper and lower surfaces of the electric auxiliary heating assembly 1. Both the upper surface of the electric auxiliary heating assembly 1 and the upper surface of the first reinforcing member 2 can contact the top wall of the second reinforcing member 3, and both the lower surface of the electric auxiliary heating assembly 1 and the lower surface of the first reinforcing member 2 can contact the bottom wall of the second reinforcing member 3.

[0064] As can be seen, the first reinforcing member 2 is flush with the corresponding surface of the electric auxiliary heating component 1 at both ends in the direction perpendicular to the windward surface 11, so that the overall structure of the electric auxiliary heating structure 100 is more compact. At the same time, when the second reinforcing member 3 is clamped around the outer periphery of the first reinforcing member 2 and the electric auxiliary heating component 1, the first reinforcing member 2 and the electric auxiliary heating component 1 can make better contact with the second reinforcing member 3, which is conducive to increasing the clamping area of ​​the second reinforcing member 3, enhancing the constraint effect of the second reinforcing member 3 on the electric auxiliary heating component 1 and the first reinforcing member 2, improving the overall structural strength of the electric auxiliary heating structure 100, facilitating the improvement of the reliability of the electric auxiliary heating structure 100, and reducing the risk of constraint damage to the electric auxiliary heating component 1 and the first reinforcing member 2 caused by the second reinforcing member 3.

[0065] In some embodiments, the first reinforcing member 2 has a closed ring-shaped cross-section and includes a first plate 21 and a third plate disposed opposite to each other. The first plate 21 is fixed to the electric auxiliary heating assembly 1 by a first fastener 41, and the third plate has a second through-hole for the first fastener 41 to pass through. For example, the first reinforcing member 2 is square, and a hole is drilled in the third plate to form the second through-hole. The structure is relatively simple and easy to process and manufacture.

[0066] As can be seen, the cross-section of the first reinforcing member 2 is a closed ring, which enables the first reinforcing member 2 to have better structural strength, thereby improving the overall bending resistance of the first reinforcing member 2 and the electric auxiliary heating assembly 1, and facilitating the improvement of the reliability of the electric auxiliary heating structure 100. A second through-hole is formed on the third plate, providing space for the first fastener 41 to pass through, so that the third plate does not easily interfere with the first fastener 41 in fixing the first plate 21 and the electric auxiliary heating assembly 1, thus reducing the assembly difficulty of the first reinforcing member 2 and the electric auxiliary heating assembly 1 and improving assembly efficiency.

[0067] It is understood that in the above scheme, the second through-hole is used for the first fastener 41 to pass through. The first fastener 41 can fix both the first plate 21 and the third plate to the electric auxiliary heating assembly 1. For example, the first fastener 41 passes through the first plate 21 and the third plate and is threadedly connected to the electric auxiliary heating assembly 1. Alternatively, the second through-hole is used for the first fastener 41 to pass through. The first fastener 41 fixes the first plate 21 and the electric auxiliary heating assembly 1, and the third plate is not connected to the first fastener 41. In this case, the second through-hole is used to avoid the first fastener 41 and facilitate the installation of the first fastener 41. For example, the first fastener 41 passes through the first plate 21 and is threadedly connected to the electric auxiliary heating assembly 1. The head of the first fastener 41 can be located between the first plate 21 and the third plate.

[0068] Please refer to Figures 3-5 In some embodiments, a through hole 24 is formed on the first reinforcing member 2, a first fastener 41 passes through the through hole 24 and is threadedly connected to the electric auxiliary heating assembly 1, and the diameter of the through hole 24 (e.g. Figure 5 L1 in the first fastener 41 is smaller than the major diameter of the thread (e.g., L1 in the first fastener 41). Figure 5 L2 in the middle); and / or, the first reinforcing member 2 is a sheet metal part.

[0069] The first fastener 41 is threadedly connected to the electric auxiliary heating assembly 1, and the diameter of the through hole 24 is smaller than the major diameter of the thread of the first fastener 41, so as to improve the connection strength between the first reinforcing member 2 and the electric auxiliary heating assembly 1. The first fastener 41 is not easy to loosen and fall out of the through hole 24, and the first reinforcing member 2 and the electric auxiliary heating assembly 1 can maintain a reliable connection, which facilitates the improvement of the reliability of the electric auxiliary heating structure 100. For example, the electric auxiliary heating structure 100 is used in an air conditioner 200, which includes a heat exchanger structure 6 and a fan. The fan is located downstream of the heat exchanger structure 6, and the electric auxiliary heating structure 100 is located on the heat exchanger structure 6. When the air conditioner 200 is subjected to external impact or vibration, the electric auxiliary heating structure 100 may collide with the heat exchanger structure 6 and / or the fan. By setting the diameter of the through hole 24 to be smaller than the major diameter of the thread of the first fastener 41, the first fastener 41 is less likely to loosen and fall out of the through hole 24 when the electric auxiliary heating structure 100 collides with the heat exchanger structure 6 and / or the fan, thereby improving the reliability of the electric auxiliary heating structure 100.

[0070] The first reinforcing member 2 is a sheet metal part. Sheet metal parts have the advantages of high strength and lightweight, are easy to stamp and form, have high processing efficiency and low cost, which makes it easier to reduce the processing difficulty of the first reinforcing member 2, which is conducive to the mass production of the electric auxiliary heating structure 100, and can reduce the overall weight of the electric auxiliary heating structure 100, thus realizing the lightweight design of the electric auxiliary heating structure 100.

[0071] Please refer to Figure 1 and Figure 2 In some embodiments, there are multiple second reinforcing members 3, and the multiple second reinforcing members 3 are spaced apart along the length direction of the electric auxiliary heating assembly 1. The multiple second reinforcing members 3 can be clamped at different positions of the electric auxiliary heating assembly 1 and the first reinforcing member 2 in order to improve the overall structural strength of the electric auxiliary heating structure 100, further improve the torsional resistance of the electric auxiliary heating structure 100, and facilitate the improvement of the reliability of the electric auxiliary heating structure 100.

[0072] Wherein, the distance between two adjacent second reinforcing members 3 (e.g.) Figure 1 The distance between L3 and the end of the electric auxiliary heating assembly 1 is greater than the distance between the second reinforcing member 3 and the end of the electric auxiliary heating assembly 1 (e.g., L3). Figure 1 The second reinforcing member 3 is positioned closer to the long end of the electric auxiliary heating assembly 1 (L4 in the figure), so that the second reinforcing member 3 can constrain the long end of the electric auxiliary heating assembly 1 to a certain extent, effectively suppressing deformation, loosening, separation, etc. of the long end of the electric auxiliary heating assembly 1, and improving the reliability of the electric auxiliary heating structure 100.

[0073] It is understandable that the multiple second reinforcing members 3 can be set at equal intervals or at unequal intervals.

[0074] Please refer to Figure 1 and Figure 2In some embodiments, at least one of the electric auxiliary heating assembly 1 and the first reinforcing member 2 is fixedly connected to the second reinforcing member 3. For example, the electric auxiliary heating assembly 1 is fixedly connected to the second reinforcing member 3, and the first reinforcing member 2 is not connected to the second reinforcing member 3; or, for another example, the first reinforcing member 2 is fixedly connected to the second reinforcing member 3, and the electric auxiliary heating assembly 1 is not connected to the second reinforcing member 3; or, for yet another example, both the electric auxiliary heating assembly 1 and the first reinforcing member 2 are fixedly connected to the second reinforcing member 3.

[0075] It can be seen that by fixing at least one of the electric auxiliary heating component 1 and the first reinforcing member 2 to the second reinforcing member 3, the position of the second reinforcing member 3 in the length direction of the electric auxiliary heating component 1 is stabilized, so that the second reinforcing member 3 can be more stably clamped to the outer periphery of the electric auxiliary heating component 1 and the first reinforcing member 2, which is conducive to improving the overall structural strength of the electric auxiliary heating structure 100. Even if the electric auxiliary heating structure 100 is subjected to impact, vibration, etc., the electric auxiliary heating structure 100 is not prone to large deformation, which is conducive to improving the reliability of the electric auxiliary heating structure 100.

[0076] Please refer to Figure 1 , Figure 2 and Figure 7 In some embodiments, the second reinforcing member 3 is formed as a closed ring structure, for example, the second reinforcing member 3 is square, the structure is relatively simple and easy to process and manufacture; the second reinforcing member 3 is sleeved outside the electric auxiliary heating assembly 1 and the first reinforcing member 2, for example, the electric auxiliary heating assembly 1 and the first reinforcing member 2 are inserted inside the second reinforcing member 3, so that the electric auxiliary heating structure 100 can have better structural strength and improve the reliability of the electric auxiliary heating structure 100.

[0077] Please refer to Figure 8 and Figure 9 In other embodiments of this application, the second reinforcing member 3 is formed as an open ring structure, and the second reinforcing member 3 has an opening 31, so as to reduce the manufacturing material of the second reinforcing member 3 and reduce the manufacturing cost of the second reinforcing member 3. When the second reinforcing member 3 is assembled with the electric auxiliary heating assembly 1 and the first reinforcing member 2, by providing the opening 31, the second reinforcing member 3 can undergo a certain deformation, so that the second reinforcing member 3 can be more easily clamped to the outside of the electric auxiliary heating assembly 1 and the first reinforcing member 2, so as to reduce the assembly difficulty of the second reinforcing member 3, simplify the assembly process, and improve the assembly efficiency of the electric auxiliary heating structure 100.

[0078] In this design, the opening 31 is opposite to the first reinforcing member 2, and the second reinforcing member 3 has lower structural strength at the opening 31. By setting the opening 31 and the first reinforcing member 2 opposite to each other, the structural strength of the first reinforcing member 2 can be used to compensate for the strength of the opening 31 of the second reinforcing member 3. During use, the opening 31 of the second reinforcing member 3 is less prone to large deformation, which helps to improve the reliability of the electric auxiliary heating structure 100. At the same time, the electric auxiliary heating component 1 and the opening 31 are staggered in the circumferential direction of the second reinforcing member 3, which helps to reduce the weakening of the reliability of the electric auxiliary heating component 1 due to the setting of the opening 31, and realizes the stable installation of the electric auxiliary heating component 1.

[0079] For example, the first reinforcing member 2 includes a first plate 21 and a second plate 22. The first plate 21 is fixedly connected to the electric auxiliary heating assembly 1. The second plate 22 is bent and connected to the side of the first plate 21 away from the electric auxiliary heating assembly 1. The second plate 22 is connected to both sides of the width of the first plate 21. The second plate 22 extends toward the opening 31 of the second reinforcing member 3 so that the opening 31 of the second reinforcing member 3 can also have good structural strength. The width of the opening 31 can be smaller than the width of the first reinforcing member 2, so as to facilitate the fixed connection between the first reinforcing member 2 and the second reinforcing member 3.

[0080] Please refer to Figures 3-7 In some embodiments, the second reinforcing member 3 has a square structure and includes two opposing first sidewalls 32 and two opposing second sidewalls 33. Each first sidewall 32 abuts against the electric auxiliary heating assembly 1 and the first reinforcing member 2, and one second sidewall 33 abuts against the electric auxiliary heating assembly 1 and the other second sidewall 33 abuts against the first reinforcing member 2. Exemplarily, when the electric auxiliary heating structure 100 is used in a wall-mounted air conditioner, the second reinforcing member 3 includes two opposing first sidewalls 32 in the vertical direction and two opposing second sidewalls 33 in the front-back direction. The upper and lower first sidewalls 32 abut against the electric auxiliary heating assembly 1 and the first reinforcing member 2, the left second sidewall 33 abuts against the electric auxiliary heating assembly 1, and the right second sidewall 33 abuts against the first reinforcing member 2. Therefore, the electric auxiliary heating component 1 and the first reinforcing member 2 can be inserted into the second reinforcing member 3, and the electric auxiliary heating component 1 and the first reinforcing member 2 can abut against the corresponding side wall of the second reinforcing member 3, so that the second reinforcing member 3 can be well clamped to the outside of the electric auxiliary heating component 1 and the first reinforcing member 2, which facilitates the improvement of the connection strength between the electric auxiliary heating component 1 and the first reinforcing member 2, thereby improving the overall structural strength of the electric auxiliary heating structure 100, making it less prone to large deformation, and facilitating the improvement of the reliability of the electric auxiliary heating structure 100.

[0081] In some embodiments, the first reinforcing member 2 includes a first plate 21, on which a second fastener is provided. The second fastener passes through the second reinforcing member 3 and is connected to the electric auxiliary heating assembly 1. Exemplarily, the first reinforcing member 2 is a flat plate, or the first reinforcing member 2 includes not only the first plate 21 but also a second plate 22.

[0082] It can be seen that the second fastener can fix the first reinforcing member 2, the second reinforcing member 3 and the electric auxiliary heating assembly 1. That is, the second fastener can fix the first reinforcing member 2, the second reinforcing member 3 and the electric auxiliary heating assembly 1 into a whole, so that the electric auxiliary heating structure 100 has good structural strength, while reducing the number of fasteners used and reducing the assembly difficulty of the electric auxiliary heating structure 100.

[0083] For example, the second fastener is a threaded fastener (such as a screw).

[0084] Please refer to Figures 1-5 In some embodiments, the second reinforcing member 3 is fixed to the first reinforcing member 2 by a third fastener 42 and a fourth fastener 43, which are arranged opposite each other in a direction perpendicular to the windward surface 11. For example, the windward surface 11 is a horizontal plane, and the third fastener 42 and the fourth fastener 43 are arranged opposite each other in a vertical direction.

[0085] As can be seen, the second reinforcing member 3 is fixed to the first reinforcing member 2 by the third fastener 42 and the fourth fastener 43, so that the second reinforcing member 3 and the first reinforcing member 2 can have better connection strength. The second reinforcing member 3 can be more stably clamped to the outside of the electric auxiliary heating assembly 1 and the first reinforcing member 2, which is conducive to improving the overall structural strength of the electric auxiliary heating structure 100, making it less prone to large deformation, and improving the reliability of the electric auxiliary heating structure 100.

[0086] For example, the first reinforcing member 2 includes a first plate 21 and two second plates 22. The first plate 21 is fixedly connected to the electric auxiliary heating assembly 1. One of the second plates 22 is fixed to the second reinforcing member 3 by a third fastener 42, and the other second plate 22 is fixed to the second reinforcing member 3 by a fourth fastener 43.

[0087] For example, the third fastener 42 is a threaded fastener (such as a screw). For example, the fourth fastener 43 is a threaded fastener (such as a screw).

[0088] In some embodiments, please refer to Figures 1-5 The second reinforcing member 3 has an opening 31, and the third fastener 42 and the fourth fastener 43 are located on opposite sides of the opening 31, respectively; and / or, the third fastener 42 and the fourth fastener 43 are offset in the length direction of the electric auxiliary heating assembly 1.

[0089] By placing the third fastener 42 and the fourth fastener 43 on opposite sides of the opening 31, the third fastener 42 and the fourth fastener 43 can fix a portion of the second reinforcing member 3 adjacent to the opening 31 to the first reinforcing member 2. This allows the portion of the second reinforcing member 3 adjacent to the opening 31 to have better structural strength, and the portion of the second reinforcing member 3 adjacent to the opening 31 is less prone to large deformation after assembly, thus improving the reliability of the electric auxiliary heating structure 100. For example, the opening 31 is opposite to the first reinforcing member 2. The first reinforcing member 2 includes a first plate 21 and a second plate 22. The first plate 21 is fixedly connected to the electric auxiliary heating assembly 1, and the second plate 22 is bent and connected to the side of the first plate 21 away from the electric auxiliary heating assembly 1. The second plate 22 is connected to both sides of the width of the first plate 21. The third fastener 42 can pass through the second reinforcing member 3 and one of the second plates 22, and the fourth fastener 43 can pass through the second reinforcing member 3 and the other second plate 22.

[0090] The third fastener 42 and the fourth fastener 43 are staggered along the length of the electric auxiliary heating assembly 1 so that there is a certain gap between them, making it less likely for them to interfere with each other. This reduces the assembly difficulty of the third fastener 42 and the fourth fastener 43, improves the assembly efficiency of the electric auxiliary heating structure 100, and helps to reduce the requirements on the corresponding dimensions of the first reinforcing member 2, for example, it makes it easier to appropriately reduce the width of the first reinforcing member 2.

[0091] Please refer to Figure 1 and Figure 2 In some embodiments, the electric auxiliary heating assembly 1 includes at least one heating core 12, a heat sink 13, and a fixing plate 14. The heating core 12 has fixing plates 14 spaced apart on both sides of its width in the windward direction 11. The fixing plates 14 extend along the length of the windward direction 11. The heat sink 13 connects the fixing plate 14 and the heating core 12. The heat sink 13 is constructed in a wave-shaped structure, with the crests of the wave-shaped structure connecting to the heating core 12 and the troughs connecting to the fixing plate 14. For example, when the electric auxiliary heating structure 100 is used in a wall-mounted air conditioner, if the electric auxiliary heating structure 100 is fixedly installed, the length direction of the windward direction 11 can be left-right, and the width direction of the windward direction 11 can be front-back. The heating core 12 has fixing plates 14 spaced apart in the front-back direction, and the heat sink 13 connects the fixing plate 14 and the heating core 12. Of course, the electric auxiliary heating structure 100 can also be rotatably installed.

[0092] As can be seen, the heat sink 13 is constructed with a wave-shaped structure. The contact between the wave-shaped heat sink 13 and the heating core 12 is a surface contact. Therefore, the heat generated in the heating core 12 can be transferred to the heat sink 13 over a large area, thereby quickly dissipating the heat outward. At the same time, the wave-shaped heat sink 13 has a large surface area, so it dissipates more heat and has better thermal conductivity, thereby improving the heating capacity of the electric auxiliary heating assembly 1. It also helps to reduce the obstruction of the airflow towards the windward surface 11 by the heat sink 13, thus reducing the wind resistance at the electric auxiliary heating assembly 1. For example, the electric auxiliary heating structure 100 is used in the air conditioner 200 to improve the heating capacity of the air conditioner 200.

[0093] It is understood that the electric auxiliary heating assembly 1 may include one or more heating cores 12. When there are multiple heating cores 12, the multiple heating cores 12 may be spaced apart along the width direction of the windward surface 11, and each heating core 12 is provided with a fixing plate 14 spaced apart on both sides of the windward surface 11. A heat sink 13 is connected between the fixing plate 14 and the heating core 12.

[0094] An air conditioner 200 according to a second aspect of the present invention includes an electric auxiliary heating structure 100 according to a first aspect of the present invention.

[0095] According to the embodiment of the present utility model, the air conditioner 200 described above has good structural strength and occupies less space. Therefore, the use of the electric auxiliary heating structure 100 can facilitate the miniaturization design of the air conditioner 200.

[0096] It is understood that the type of air conditioner 200 in this application embodiment is not limited. It can be a vehicle air conditioner, an integrated air conditioner, or a split air conditioner. An integrated air conditioner can include a window air conditioner or a portable air conditioner, and a split air conditioner can include a wall-mounted air conditioner or a floor-standing air conditioner.

[0097] Please refer to Figures 11-13 In some embodiments, the air conditioner 200 includes a heat exchanger structure 6, which includes a heat exchange body 61, a first supporting side plate 62, and a second supporting side plate 63. The first supporting side plate 62 and the second supporting side plate 63 are respectively disposed at both ends of the length of the heat exchange body 61. The heat exchange body 61 is constructed as a bent structure and includes a plurality of heat exchange parts 611 that are bent and spliced ​​in sequence. The heat exchange body 61 can be formed as a multi-fold structure. The electric auxiliary heating component 1 is fixed between the first supporting side plate 62 and the second supporting side plate 63, and the electric auxiliary heating component 1 is located within the bent structure. Exemplarily, the electric auxiliary heating component 1 is located within the space enclosed by the first supporting side plate 62, the heat exchanger structure 6, and the second supporting side plate 63.

[0098] As can be seen, the first support plate 62 and the second support plate 63 are respectively located at both ends of the length of the heat exchange body 61, providing space for the installation of the electric auxiliary heating component 1, and facilitating the connection between the heat exchanger structure 6 and other components of the air conditioner 200; the heat exchange body 61 includes a plurality of heat exchange sections 611 that are bent and spliced ​​in sequence, so as to increase the heat exchange area of ​​the heat exchange body 61, which is conducive to improving the heat exchange capacity of the heat exchange body 61, thereby improving the cooling and heating effect of the air conditioner 200.

[0099] Please refer to Figure 1 , Figure 2 and Figures 11-13 In some embodiments, the electric auxiliary heating component 1 has support seats 5 at both ends of its length. Each support seat 5 has a plug-in cavity 51 for inserting the electric auxiliary heating component 1. One of the support seats 5 also has a wiring port 52 communicating with the plug-in cavity 51 on the side opposite to the electric auxiliary heating component 1. It can be seen that by providing the plug-in cavity 51, the electric auxiliary heating component 1 and the support seat 5 can be plugged together, which reduces the assembly difficulty of the electric auxiliary heating component 1 and the support seat 5. At the same time, the support seat 5 can be used to install the electric auxiliary heating component 1 into other components of the air conditioner 200 (such as the heat exchanger structure 6 mentioned above). Furthermore, by providing the wiring port 52 communicating with the plug-in cavity 51, the support seat 5 is less likely to affect the wiring of the electric auxiliary heating structure 100, thus improving the reliability of the electric auxiliary heating component 1.

[0100] Please refer to Figure 1 , Figure 2 and Figures 11-13 In some embodiments, the electric auxiliary heating component 1 is provided with support bases 5 at both ends of its length. One of the support bases 5 has a wire passage 52. The first support side plate 62 cooperates with one of the support bases 5, and the first support side plate 62 has a wire-holding groove opposite to the wire passage 52. By setting the wire-holding groove, a clear path is provided for the wiring of the electric auxiliary heating component 1, which makes it easier to reduce the wiring difficulty of the electric auxiliary heating component 1. For example, the wiring of the electric auxiliary heating component 1 can be connected to the electrical control box of the air conditioner 200 through the wire-holding groove, and it is not easy to interfere with the heat exchanger structure 6, which makes it easier to improve the assembly efficiency of the air conditioner 200.

[0101] Furthermore, one of the support bases 5 includes a cable passage 52 and a plug-in portion 53. The plug-in portion 53 is located on the side of the cable passage 52 adjacent to the first support side plate 62. For example, the plug-in portion 53 is configured as a cylinder so that the plug-in portion 53 and the first support side plate 62 can be connected by plugging, making the assembly simpler. At the same time, the plug-in portion 53 also allows for a certain distance between the cable passage 52 and the first support side plate 62, providing more space for the cable passage 52 and the cable slot, which helps to reduce the assembly difficulty of the electric auxiliary heating component 1 and the heat exchanger structure 6.

[0102] Please refer to Figure 1 , Figure 2 and Figures 11-13 In some embodiments, one support base 5 includes a cable passage 52 and a plug-in portion 53. The support base 5 mates with the first support side plate 62, and the other support base 5 mates with the second support side plate 63. The second support side plate 63 includes a slot 631, and the other support base 5 can be directly snapped into the slot 631. For example, the outer contour of the other support base 5 is adapted to the shape of the slot 631, which helps to reduce assembly difficulty. Furthermore, the outer contour of the other support base 5 and the shape of the slot 631 are both non-circular, so that the other support base 5 is not easily rotated after being fitted into the slot 631, which facilitates the positioning of the electric auxiliary heating component 1 and simplifies the assembly of the air conditioner 200.

[0103] For example, the electric auxiliary heating assembly 1 has support seats 5 at both ends of its length. One of the support seats 5 has a plug-in part 53, which is plugged into and cooperates with the first support side plate 62. The second support side plate 63 includes a slot 631. The outer contour of the other support seat 5 is adapted to the shape of the slot 631. The outer contour of the other support seat 5 and the shape of the slot 631 are both non-circular, so that the other support seat 5 can be directly plugged into the slot 631. This simplifies the assembly process of the electric auxiliary heating assembly 1 and the heat exchanger and improves the assembly efficiency of the air conditioner 200.
