Description

Technical Field

[0001] This utility model relates to the technical field of fixing electric heaters, and more particularly to a reinforcing component of an electric heater and an air conditioning unit formed therefrom. Background Technology

[0002] In floor-standing air conditioners, the electric heater is mainly used to supplement heat in heating mode, especially in low-temperature environments, to improve user comfort. In round air conditioners, the electric heater is typically a straight strip that covers the entire air outlet area, with a length of about one meter, and is installed in the open area at the front of the evaporator component.

[0003] In existing technologies, the electric heater is made of aluminum sheet, which has low strength. During the handling and transportation of the entire machine, it is prone to deformation due to being dropped or not handled with care. After deformation, the electric heater is likely to collide with the evaporator fins, affecting the normal operation of the evaporator. At the same time, since the electric heater operates with high voltage, a collision with it poses an electrical safety hazard to the entire machine.

[0004] In existing technologies, the electric heater is fixed to the air conditioner casing or other panels using a fixed bracket or other structure. This fixed bracket structure is unstable and cannot prevent the electric heater from deforming when the air conditioner is subjected to strong external impact. Utility Model Content

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a reinforcing component for an electric heater. The reinforcing component provides support and reinforcement for the electric heater, thereby enhancing the strength of the electric heater itself. When the electric heater is subjected to impact, the reinforcing component can protect and strengthen it, preventing the electric heater from deforming.

[0006] A reinforcing assembly for an electric heater includes a reinforcing member and a fixing member, the fixing member being nested outside the electric heater and the reinforcing member for fixing the electric heater and the reinforcing member;

[0007] The reinforcing member includes a first support plate, a second support plate, and a connecting plate. The first support plate and the second support plate are arranged opposite to each other, and the two ends of the connecting plate are respectively connected to the first support plate and the second support plate. The first support plate is arranged parallel to the electric heater.

[0008] In this application, the first support plate, the connecting plate, and the second support plate form a U-shaped structure to ensure that the reinforcing member itself has sufficient strength. The reinforcing member and the electric heater are then fixed together by the fastener. The reinforcing member provides support and reinforcement for the electric heater, thereby enhancing the strength of the electric heater itself. When the electric heater is subjected to impact, the reinforcing member can protect and strengthen it, preventing the electric heater from deforming.

[0009] In a preferred embodiment of this invention, the length of the reinforcing member is equal to the length of the electric heater.

[0010] This application defines the length of the electric heater as the largest dimension among all dimensions of the electric heater. For example, when the heater has a cuboid structure, the direction with the largest dimension in three dimensions is the length direction. When designing the corresponding reinforcing member for the electric heater, it is ensured that the lengths of the two are equal. When assembling the electric heater and the reinforcing member, it is ensured that the electric heater and the reinforcing member fit together to the greatest extent, which can better improve the overall strength of the electric heater.

[0011] In a preferred embodiment of this invention, the fixing member has a first heat dissipation through hole and a second heat dissipation through hole, wherein the first heat dissipation through hole is nested on the outside of the electric heater and the second heat dissipation through hole is nested on the outside of the reinforcing member.

[0012] In this application, the electric heater needs to have ample space around it for better heat dissipation during the heating process. Therefore, the first support plate in the reinforcing member cannot be directly attached to the electric heater. This application uses a fastener to fix the electric heater and the reinforcing member together, forming a single unit. Simultaneously, the fastener also needs to isolate the electric heater and the reinforcing member to prevent insufficient heat dissipation caused by contact between them. Based on this, this application provides a first heat dissipation through-hole and a second heat dissipation through-hole in the fastener. The first heat dissipation through-hole is adapted to the shape of the electric heater, and the second heat dissipation through-hole is adapted to the shape of the reinforcing member. During assembly, the first and second heat dissipation through-holes are nested around the electric heater and the reinforcing member to achieve fixation. The fastener structure in this application is simple; the first and second heat dissipation through-holes achieve both fastening and isolation between the electric heater and the reinforcing member.

[0013] In a preferred embodiment of this invention, the number of fasteners is greater than or equal to two, and the fasteners are evenly distributed along the length of the reinforcing member.

[0014] To avoid affecting the normal heat dissipation of the electric heater, this application uses relatively small fasteners, ensuring fastening only at one point between the reinforcing member and the electric heater. Outside the fastener area, the electric heater remains exposed for heat dissipation. To ensure a stable fastening between the reinforcing member and the electric heater, this application uses two or more fasteners, distributed sequentially along the length of both the reinforcing member and the heater, providing fastening from multiple locations. Because the electric heater and the reinforcing member are adjacent along their length, the fasteners are also distributed along the length, achieving fastening at various locations while ensuring good heat dissipation of the electric heater outside the fastener area.

[0015] In a preferred embodiment of this invention, the sidewall of the second heat dissipation through hole is provided with a first fixing through hole, and the reinforcing member is provided with a second fixing through hole that is adapted to the first fixing through hole.

[0016] After the first and second heat dissipation through holes in the fixing component are nested on the electric heater and the reinforcing component respectively, it is necessary to fix the position of the fixing component to prevent it from sliding and causing misalignment between the electric heater and the reinforcing component. This application provides a first fixing through hole on the side wall of the second heat dissipation through hole and a second fixing through hole in the reinforcing component. Fasteners such as screws are used to sequentially pass through the second and first fixing through holes and tighten them, thus securing the reinforcing component and the fixing component. This ensures the tightness between the fixing component and the reinforcing component, as well as between the reinforcing component and the electric heater. Furthermore, the fastening screws on the reinforcing component do not affect the normal performance of the electric heater.

[0017] In a preferred embodiment of this invention, the second fixing through hole is located on the connecting plate.

[0018] To facilitate the installation of fastening screws, this application sets the second fixing through hole on the connecting plate. The first support plate is adjacent to the electric heater, making it difficult to install screws. The second support plate is far from the electric heater, making it impossible to install fastening screws. By setting the second fixing through hole on the connecting plate, and simultaneously setting the first fixing through hole on the side of the fastener where the second heat dissipation through hole coincides with the connecting plate, the fastener and the reinforcing member can be fixedly connected, and the fastener and the reinforcing member can be easily assembled, thus improving assembly efficiency.

[0019] In a preferred embodiment of this invention, both the first support plate and the second support plate have folded edges facing the connecting plate at their ends away from the connecting plate.

[0020] The first support plate, the second support plate, and the connecting plate form a U-shaped structure. The connecting plate is located at the bottom of the U-shaped structure, and the first and second support plates are located on both sides of the U-shaped structure. At the end edges of the first and second support plates away from the connecting plate, i.e., at the opening of the U-shaped structure, there are folded edges facing the connecting plate, i.e., folded edges facing the inside of the U-shaped opening. The folded edges make the edges of the reinforcing member smooth, preventing sharp edges from scratching the operator, and also increasing the overall strength of the reinforcing member.

[0021] In a preferred embodiment of this invention, ventilation holes are provided at intervals on the connecting plate along the length direction of the reinforcing member.

[0022] When setting up ventilation holes, it is first necessary to ensure that the strength of the reinforcing component meets the requirements. Once the required strength is achieved, the number and size of the ventilation holes can be designed. At this point, the ventilation holes can reduce the weight of the reinforcing component, thereby reducing the weight of the entire reinforcing assembly and the production material costs.

[0023] When the electric heater is installed inside the air conditioner, since the electric heater is located at the air outlet, the ventilation holes can reduce the resistance of the air conditioner's airflow, ensuring that the air output of the air conditioner can be output through the ventilation holes. This not only reduces the whistling sound caused by the wind blowing on the reinforcing parts, but also increases the overall air volume of the unit, avoids air volume loss, and improves the performance and comfort of the air conditioner.

[0024] In a preferred embodiment of this invention, in the width direction of the reinforcing member, the distance between the top and bottom of the vent hole and the end of the connecting plate is 1.5-2.5 mm; in the length direction of the reinforcing member, the spacing between adjacent vent holes is 9-11 mm.

[0025] In this application, the direction perpendicular to the length of the connecting plate is defined as the width direction. In the width direction of the reinforcing member, the distance between the top of the vent hole and the top of the connecting plate is 1.5-2.5mm, and the distance between the bottom of the vent hole and the bottom of the connecting plate is 1.5-2.5mm. This dimension can avoid the connecting plate having too low strength, which would affect the overall reinforcement effect, and can also ensure that the production material cost of the reinforcing member is low.

[0026] Along the length of the reinforcing member, the spacing between adjacent vent holes is 9-11 mm. This dimension prevents the connecting plate from having insufficient strength, which would affect the overall reinforcement effect, and also ensures that the production material cost of the reinforcing member is low.

[0027] The second objective of this application is to provide an air conditioning unit that includes a reinforcing component for an electric heater as described above.

[0028] After the reinforcing component and the electric heater are fixed by the fastener, they are installed at the air outlet of the air conditioner. The reinforcing component provides support and reinforcement for the electric heater, thereby increasing the strength of the electric heater itself. When the air conditioner is impacted, the reinforcing component can protect and strengthen the electric heater, preventing the electric heater from deforming.

[0029] The beneficial effects of this utility model are as follows:

[0030] This utility model provides a reinforcing assembly for an electric heater, including a reinforcing member and a fixing member. The reinforcing member includes a first support plate, a second support plate, and a connecting plate. The first and second support plates are arranged opposite to each other, and the two ends of the connecting plate are respectively connected to the first and second support plates. The first support plate is arranged parallel to the electric heater. The fixing member is nested outside the electric heater and the reinforcing member to fix the electric heater and the reinforcing member. In this application, the first support plate, the connecting plate, and the second support plate form a U-shaped structure to ensure that the reinforcing member itself has sufficient strength. The fixing member then fixes the reinforcing member and the electric heater together. The reinforcing member provides support and reinforcement for the electric heater, enhancing its strength. When the electric heater is subjected to impact, the reinforcing member can protect and strengthen it, preventing deformation of the electric heater.

[0031] This application provides an air conditioner cabinet unit, including a reinforcing component for an electric heater as described above. After the reinforcing component and the electric heater are fixed by a fastener, they are installed at the air outlet of the air conditioner. The reinforcing component provides support and reinforcement for the electric heater, thereby increasing the strength of the electric heater itself. When the air conditioner is impacted, the reinforcing component can protect and strengthen the electric heater, preventing the electric heater from deforming. Attached Figure Description

[0043] Example 1

[0044] like Figures 1-6 As shown, the present application provides a reinforcing assembly for an electric heater 31, including a reinforcing member 11 and a fixing member 21. The fixing member 21 is nested on the outside of the electric heater 31 and the reinforcing member 11 for fixing the electric heater 31 and the reinforcing member 11.

[0045] The reinforcing member 11 includes a first support plate 111, a second support plate 112, and a connecting plate 113. The first support plate 111 and the second support plate 112 are arranged opposite to each other, and the two ends of the connecting plate 113 are respectively connected to the first support plate 111 and the second support plate 112. The first support plate 111 is arranged parallel to the electric heater 31.

[0046] In this application, the electric heater 31 can specifically be an electric heater 31 installed in the air conditioner cabinet unit. The electric heater 31 located in the air conditioner cabinet unit is mainly used to assist the air conditioner in supplementing heat in the heating mode, and is installed in the hollow area at the front end of the evaporator component.

[0047] In this application, the electric heater 31 can also be used in other applications, such as inside a heating device, to ensure that the electric heater 31 has sufficient strength during the turnover and transportation of the heating device, and to prevent the electric heater 31 from being deformed by external forces.

[0048] When the reinforcing component is used inside an air conditioner cabinet unit, the reinforcing member 11 in this application is installed together with the electric heater 31. The electric heater 31 operates at a high temperature, requiring the reinforcing member 11 to withstand high temperatures. The reinforcing member 11, installed together with the electric heater 31, is located at the front end of the evaporator. In cooling mode, the reinforcing member 11 is constantly exposed to a humid environment. Therefore, the reinforcing member 11 in this application can use a hot-dip galvanized sheet Q235A 1.15X1250XC with good strength, high temperature resistance, and resistance to rust and corrosion.

[0049] In a circular cabinet air conditioner, the electric heater 31 is typically a cuboid structure, with the reinforcing member 11 arranged side-by-side with it. Preferably, the length of the reinforcing member 11 is equal to or slightly less than the length of the electric heater 31, ensuring synchronous reinforcement throughout the electric heater 31 and comprehensively improving its strength.

[0050] In this application, the first support plate 111 or the second support plate 112 needs to be set close to the electric heater 31. Therefore, the size of the first support plate 111 and the second support plate 112 can be specifically set according to the outer size of the electric heater 31 to ensure that the size of the first support plate 111 and the second support plate 112 is basically consistent with the size of the side of the electric heater 31 that is in contact with it, which can better improve the overall strength of the electric heater 31.

[0051] In this application, the first support plate 111, the connecting plate 113, and the second support plate 112 form a U-shaped structure to ensure that the reinforcing member 11 itself has sufficient strength. Then, the reinforcing member 11 and the electric heater 31 are fixed together by the fastener 21. The reinforcing member 11 provides support and reinforcement for the electric heater 31, thereby enhancing the strength of the electric heater 31 itself. When the electric heater 31 is impacted, the reinforcing member 11 can protect and reinforce it, preventing the electric heater 31 from deforming.

[0052] Example 2

[0053] like Figures 1-6 As shown, the present application provides a reinforcing assembly for an electric heater 31, including a reinforcing member 11 and a fixing member 21. The fixing member 21 is nested on the outside of the electric heater 31 and the reinforcing member 11 for fixing the electric heater 31 and the reinforcing member 11.

[0054] The reinforcing member 11 includes a first support plate 111, a second support plate 112, and a connecting plate 113. The first support plate 111 and the second support plate 112 are arranged opposite to each other, and the two ends of the connecting plate 113 are respectively connected to the first support plate 111 and the second support plate 112. The first support plate 111 is arranged parallel to the electric heater 31.

[0055] Furthermore, the length of the reinforcing member 11 is equal to the length of the electric heater 31.

[0056] This application defines the length of the electric heater 31 as the largest dimension among all dimensions of the electric heater 31. For example, when the heater is a cuboid structure, the direction in which its dimension is largest in three dimensions is the length direction. When designing the reinforcing member 11 corresponding to the electric heater 31, it is ensured that the lengths of the two are equal. When assembling the electric heater 31 and the reinforcing member 11, it is ensured that the electric heater 31 and the reinforcing member 11 fit together to the maximum extent, which can better improve the overall strength of the electric heater 31.

[0057] Furthermore, the fixing member 21 has a first heat dissipation through hole 211 and a second heat dissipation through hole 212, wherein the first heat dissipation through hole 211 is nested on the outside of the electric heater 31, and the second heat dissipation through hole 212 is nested on the outside of the reinforcing member 11.

[0058] In this application, the electric heater 31 needs to be kept spacious around it during the heating process to facilitate better heat dissipation. Therefore, the first support plate 111 in the reinforcing member 11 cannot be directly attached to the electric heater 31. This application uses a fixing member 21 to fix the electric heater 31 and the reinforcing member 11 together, forming a single unit. Simultaneously, the fixing member 21 also needs to isolate the electric heater 31 and the reinforcing member 11 to prevent insufficient heat dissipation caused by their contact. Based on this, this application provides a first heat dissipation through-hole 211 and a second heat dissipation through-hole 212 in the fixing member 21. The first heat dissipation through-hole 211 is adapted to the shape of the electric heater 31, and the second heat dissipation through-hole 212 is adapted to the shape of the reinforcing member 11. During assembly, the first heat dissipation through-hole 211 and the second heat dissipation through-hole 212 are nested around the electric heater 31 and the reinforcing member 11, thus achieving the fixation of the electric heater 31 and the reinforcing member 11. In this application, the fastener 21 has a simple structure. Through the first heat dissipation through hole 211 and the second heat dissipation through hole 212, it can both fasten the electric heater 31 and the reinforcing member 11 and isolate the electric heater 31 and the reinforcing member 11.

[0059] Furthermore, the number of the fasteners 21 is greater than or equal to two, and the fasteners 21 are evenly distributed along the length direction of the reinforcing member 11.

[0060] To avoid affecting the normal heat dissipation of the electric heater 31, the size of the fastener 21 is set to be relatively small, only enabling fastening of the reinforcing member 11 and the electric heater 31 at a single point. Outside the fastener 21, the electric heater 31 is exposed, facilitating heat dissipation. To ensure a stable fastening between the reinforcing member 11 and the electric heater 31, the application uses two or more fasteners 21, distributed sequentially along the length of the reinforcing member 11 and the heater, for fastening from multiple locations. Because the electric heater 31 and the reinforcing member 11 are adjacent in the length direction, the fasteners 21 are also distributed along the length direction, thus achieving fastening at various locations while ensuring good heat dissipation of the electric heater 31 outside the fastener 21.

[0061] Furthermore, the sidewall of the second heat dissipation through hole 212 is provided with a first fixing through hole 213, and the reinforcing member 11 is provided with a second fixing through hole 116 that is adapted to the first fixing through hole 213.

[0062] After the first heat dissipation through hole 211 and the second heat dissipation through hole 212 in the fixing member 21 are respectively nested on the electric heater 31 and the reinforcing member 11, it is also necessary to fix the position of the fixing member 21 to prevent it from sliding and causing misalignment between the electric heater 31 and the reinforcing member 11. In this application, a first fixing through hole 213 is provided on the side wall of the second heat dissipation through hole 212, and a second fixing through hole 116 is provided in the reinforcing member 11. By using fasteners such as fastening screws to pass through the second fixing through hole 116 and the first fixing through hole 213 in sequence and tightening them, the reinforcing member 11 and the fixing member 21 are fastened. In this way, the fastening between the fixing member 21 and the reinforcing member 11 can be ensured, and the fastening between the reinforcing member 11 and the electric heater 31 can also be ensured. At the same time, the fastening screws provided on the reinforcing member 11 will not affect the normal performance of the electric heater 31.

[0063] Furthermore, the second fixing through hole 116 is located on the connecting plate 113.

[0064] To facilitate the installation of fastening screws, this application sets the second fixing through hole 116 on the connecting plate 113. The first support plate 111 is adjacent to the electric heater 31, making it difficult to install screws. The second support plate 112 is far from the electric heater 31, making it impossible to install fastening screws. The second fixing through hole 116 is set on the connecting plate 113. At the same time, the first fixing through hole 213 is set on the side of the fastener 21 where the second heat dissipation through hole 212 overlaps with the connecting plate 113. This not only realizes the fixed connection between the fastener 21 and the reinforcing member 11, but also ensures convenient assembly between the fastener 21 and the reinforcing member 11, improving assembly efficiency.

[0065] Furthermore, the end edges of the first support plate 111 and the second support plate 112 away from the connecting plate 113 are both provided with folded edge structures 115 facing the connecting plate 113.

[0066] The first support plate 111, the second support plate 112, and the connecting plate 113 form a U-shaped structure. The connecting plate 113 is located at the bottom of the U-shaped structure, and the first support plate 111 and the second support plate 112 are located on both sides of the U-shaped structure. At the end edges of the first support plate 111 and the second support plate 112 away from the connecting plate 113, i.e., at the opening of the U-shaped structure, a folded edge structure 115 is provided facing the connecting plate 113, i.e., the folded edge structure 115 facing the inside of the U-shaped opening. The folded edge structure 115 can make the edge of the reinforcing member 11 smooth, avoid sharp edges from scratching the operator, and also increase the overall strength of the reinforcing member 11.

[0067] Furthermore, in the length direction of the reinforcing member 11, the connecting plate 113 is provided with ventilation holes 114 at intervals.

[0068] When setting the ventilation holes 114, it is necessary to first ensure that the strength of the reinforcing member 11 meets the requirements. Once the required strength is achieved, the number and size of the ventilation holes 114 can be designed. At this point, the ventilation holes 114 can reduce the weight of the reinforcing member 11, thereby reducing the weight of the entire reinforcing assembly and the cost of production materials.

[0069] When the electric heater 31 is installed inside the air conditioner, since the electric heater 31 is located at the air outlet 32 ​​of the air conditioner, the ventilation hole 114 can reduce the resistance of the air conditioner's air outlet, ensuring that the air force output by the air conditioner can be output through the ventilation hole 114. This not only reduces the whistling sound formed by the wind blowing on the reinforcing member 11, but also increases the air volume of the whole unit, avoids air volume loss, and improves the performance and comfort of the air conditioner.

[0070] Furthermore, in the width direction of the reinforcing member 11, the distance between the top and bottom of the vent hole 114 and the end of the connecting plate 113 is 1.5-2.5mm; in the length direction of the reinforcing member 11, the spacing between adjacent vent holes 114 is 9-11mm.

[0071] In this application, the direction perpendicular to the length of the connecting plate 113 is defined as the width direction. In the width direction of the reinforcing member 11, the distance between the top of the vent hole 114 and the top of the connecting plate 113 is 1.5-2.5mm, and the distance between the bottom of the vent hole 114 and the bottom of the connecting plate 113 is 1.5-2.5mm. This dimension can avoid the connecting plate 113 having too low strength, which would affect the overall reinforcement effect, and can also ensure that the production material cost of the reinforcing member 11 is low.

[0072] Along the length of the reinforcing member 11, the spacing between adjacent vent holes 114 is 9-11 mm. This dimension avoids the connecting plate 113 having too low strength, which would affect the overall reinforcement effect, and also ensures that the production material cost of the reinforcing member 11 is low.

[0073] Example 3

[0074] like Figures 1-6 As shown, this application provides a reinforcing component for an electric heater 31, used to strengthen the electric heater 31 and prevent it from deforming under external forces. Specifically, the electric heater 31 has a cuboid structure, with its length direction defined as the direction of the largest dimension in the electric heater 31; its height direction defined as the direction of the smallest dimension in the electric heater 31; and its width direction defined as the perpendicular direction in the same plane as the length direction.

[0075] The reinforcing assembly includes a reinforcing member 11 and a fixing member 21. The fixing member 21 is nested outside the electric heater 31 and the reinforcing member 11 to fix the electric heater 31 and the reinforcing member 11. The reinforcing member 11 and the electric heater 31 are arranged adjacent to each other to reinforce and protect the electric heater 31.

[0076] like Figures 1-3 As shown, the reinforcing member 11 includes a first support plate 111, a second support plate 112, and a connecting plate 113. The first support plate 111 and the second support plate 112 are arranged opposite to each other, and the two ends of the connecting plate 113 are respectively connected to the first support plate 111 and the second support plate 112. The first support plate 111, the second support plate 112, and the connecting plate 113 form a U-shaped structure. The connecting plate 113 is located at the bottom of the U-shaped structure, and the first support plate 111 and the second support plate 112 are located on both sides of the U-shaped structure. At the end edges of the first support plate 111 and the second support plate 112 away from the connecting plate 113, i.e., at the opening of the U-shaped structure, a folded edge structure 115 is provided facing the connecting plate 113, i.e., the folded edge structure 115 facing the inside of the U-shaped opening. The folded edge structure 115 can make the edge of the reinforcing member 11 smooth, avoiding sharp edges from scratching the operator, and also increasing the overall strength of the reinforcing member 11.

[0077] In this application, the length of the first support plate 111 is equal to the length of the electric heater 31, and the width of the first support plate 111 is equal to the width of the electric heater 31, or the length of the first support plate 111 is slightly less than the length of the electric heater 31, and the width of the first support plate 111 is slightly less than the width of the electric heater 31. During assembly, the first support plate 111 is set to be parallel to the plane containing the long side and the wide side of the electric heater 31, ensuring that the electric heater 31 and the reinforcing member 11 fit together to the maximum extent, which can better improve the overall strength of the electric heater 31.

[0078] Along the length of the reinforcing member 11, the connecting plate 113 is provided with ventilation holes 114 at intervals. When setting the ventilation holes 114, it is first necessary to ensure that the strength of the reinforcing member 11 meets the requirements. After the required strength is met, the number and size of the ventilation holes 114 are then designed. At this time, the ventilation holes 114 can reduce the weight of the reinforcing member 11, thereby reducing the weight of the entire reinforcing assembly and the production material cost.

[0079] In the width direction of the reinforcing member 11, the distance between the top and bottom of the vent hole 114 and the end of the connecting plate 113 is 2mm; in the length direction of the reinforcing member 11, the spacing between adjacent vent holes 114 is 10mm.

[0080] like Figure 4As shown, the fixing member 21 has a first heat dissipation through hole 211 and a second heat dissipation through hole 212, wherein the first heat dissipation through hole 211 is nested on the outside of the electric heater 31, and the second heat dissipation through hole 212 is nested on the outside of the reinforcing member 11. There are four fixing members 21, which are distributed along the length of the reinforcing member 11, with two fixing members 21 located at both ends of the reinforcing member 11 and the other two fixing members 21 located in the middle of the reinforcing member 11.

[0081] The second heat dissipation through-hole 212 has a first fixing through-hole 213 on its side wall, and the connecting plate 113 has a second fixing through-hole 116 that matches the first fixing through-hole 213. By using fasteners such as screws to sequentially pass through the second fixing through-hole 116 and the first fixing through-hole 213 and tighten them, the reinforcing member 11 and the fixing member 21 are secured. This ensures the secure connection between the fixing member 21 and the reinforcing member 11, as well as the secure connection between the reinforcing member 11 and the electric heater 31. Furthermore, the fastening screws on the reinforcing member 11 do not affect the normal performance of the electric heater 31. The second fixing through-hole 116 is provided on the connecting plate 113, and the first fixing through-hole 213 is provided on the side of the fixing member 21 where the second heat dissipation through-hole 212 overlaps with the connecting plate 113. This not only achieves a fixed connection between the fixing member 21 and the reinforcing member 11, but also ensures convenient assembly between the fixing member 21 and the reinforcing member 11, improving assembly efficiency.

[0082] Example 4

[0083] like Figures 1-6 As shown, an air conditioner cabinet unit has the structure described in the prior art. An electric heater 31 is installed at the air outlet of the air conditioner cabinet unit. The electric heater 31 is mainly used to supplement heat in the air conditioner in heating mode. In particular, the electric heater 31 is turned on for auxiliary heating in low temperature environment, which can improve the user's comfort.

[0084] The electric heater 31 is reinforced by a reinforcing component, and the reinforced electric heater 31 and the reinforcing component 11 are fixed to the hollow area at the front end of the evaporator component.

[0085] In this embodiment, the air conditioner unit is a circular air conditioner unit. The electric heater 31 in the circular air conditioner unit has a cuboid structure and needs to cover the entire air outlet area of ​​the air conditioner. Its length is about one meter. The direction with the largest size in the electric heater 31 is defined as its length direction; the direction with the smallest size in the electric heater 31 is defined as its height direction; and the perpendicular direction in the same plane as the length direction is defined as its width direction.

[0086] When the reinforcing component is used inside an air conditioner cabinet unit, the reinforcing member 11 in this application is installed together with the electric heater 31. The electric heater 31 operates at a high temperature, requiring the reinforcing member 11 to withstand high temperatures. The reinforcing member 11, installed together with the electric heater 31, is located at the front end of the evaporator. In cooling mode, the reinforcing member 11 is constantly exposed to a humid environment. Therefore, the reinforcing member 11 in this application can be made of hot-dip galvanized steel sheet with good strength, high temperature resistance, and resistance to rust and corrosion.

[0087] The reinforcing assembly includes a reinforcing member 11 and a fixing member 21. The fixing member 21 is nested outside the electric heater 31 and the reinforcing member 11 to fix the electric heater 31 and the reinforcing member 11. The reinforcing member 11 and the electric heater 31 are arranged adjacent to each other to reinforce and protect the electric heater 31.

[0088] The reinforcing member 11 includes a first support plate 111, a second support plate 112, and a connecting plate 113. The first support plate 111 and the second support plate 112 are arranged opposite to each other, and the two ends of the connecting plate 113 are respectively connected to the first support plate 111 and the second support plate 112. The first support plate 111, the second support plate 112, and the connecting plate 113 form a U-shaped structure. The connecting plate 113 is located at the bottom of the U-shaped structure, and the first support plate 111 and the second support plate 112 are located on both sides of the U-shaped structure. At the end edges of the first support plate 111 and the second support plate 112 away from the connecting plate 113, i.e., at the opening of the U-shaped structure, a folded edge structure 115 is provided facing the connecting plate 113, i.e., the folded edge structure 115 facing the inside of the U-shaped opening. The folded edge structure 115 can make the edge of the reinforcing member 11 smooth, avoid sharp edges from scratching the operator, and also increase the overall strength of the reinforcing member 11.

[0089] In this application, the length of the first support plate 111 is equal to the length of the electric heater 31, and the width of the first support plate 111 is equal to the width of the electric heater 31. During assembly, the first support plate 111 is set to be parallel to the plane containing the long side and the wide side of the electric heater 31, ensuring that the electric heater 31 and the reinforcing member 11 fit together to the maximum extent, which can better improve the overall strength of the electric heater 31.

[0090] Along the length of the reinforcing member 11, the connecting plate 113 is provided with ventilation holes 114 at intervals. When setting the ventilation holes 114, it is first necessary to ensure that the strength of the reinforcing member 11 meets the requirements. After the required strength is met, the number and size of the ventilation holes 114 are then designed. At this time, the ventilation holes 114 can reduce the weight of the reinforcing member 11, thereby reducing the weight of the entire reinforcing assembly and the production material cost.

[0091] When the electric heater 31 is installed inside the air conditioner, since the electric heater 31 is located at the air outlet 32 ​​of the air conditioner, the ventilation hole 114 can reduce the resistance of the air conditioner's air outlet, ensuring that the air force output by the air conditioner can be output through the ventilation hole 114. This not only reduces the whistling sound formed by the wind blowing on the reinforcing member 11, but also increases the air volume of the whole unit, avoids air volume loss, and improves the performance and comfort of the air conditioner.

[0092] In the width direction of the reinforcing member 11, the distance between the top and bottom of the vent hole 114 and the end of the connecting plate 113 is 2mm; in the length direction of the reinforcing member 11, the spacing between adjacent vent holes 114 is 10mm.

[0093] like Figures 4-6 As shown, the fixing member 21 has a first heat dissipation through hole 211 and a second heat dissipation through hole 212, wherein the first heat dissipation through hole 211 is nested on the outside of the electric heater 31, and the second heat dissipation through hole 212 is nested on the outside of the reinforcing member 11. There are four fixing members 21, which are distributed along the length of the reinforcing member 11, with two fixing members 21 located at both ends of the reinforcing member 11 and the other two fixing members 21 located in the middle of the reinforcing member 11.

[0094] The side wall of the second heat dissipation through hole 212 is provided with a first fixing through hole 213, and the connecting plate 113 is provided with a second fixing through hole 116 adapted to the first fixing through hole 213. By means of fastening screws and other fasteners passing through the second fixing through hole 116 and the first fixing through hole 213 in sequence and tightening them, the reinforcement 11 and the fixing member 21 are fastened. The second fixing through hole 116 is provided on the connecting plate 113, and the first fixing through hole 213 is provided on the side of the fixing member 21 where the second heat dissipation through hole 212 coincides with the connecting plate 113. This can not only realize the fixed connection between the fixing member 21 and the reinforcement 11, but also ensure the convenient assembly between the fixing member 21 and the reinforcement 11, and improve the assembly efficiency.

[0095] This application provides an air conditioner cabinet unit, including a reinforcing component for an electric heater 31 as described above. After the reinforcing component 11 and the electric heater 31 are fixed by the fixing component 21, they are installed at the air outlet 32 ​​of the air conditioner. The reinforcing component 11 provides support and reinforcement for the electric heater 31, thereby enhancing the strength of the electric heater 31 itself. When the air conditioner is impacted, the reinforcing component 11 can protect and reinforce the electric heater 31, preventing the electric heater 31 from deforming.
