Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to an electric heating installation protection structure for air conditioners. Background Art

[0002] When the electric heater of the air duct unit of the air conditioner is assembled, the electric heater needs to maintain a certain distance from the air duct and other components inside the air conditioner, and the space between the heating wire of the electric heater and the air duct cannot be obstructed. Therefore, it is a difficult problem to install the electric heater stably on the air conditioner. The current traditional installation method is to use a sheet metal mounting plate, one end of the mounting plate is screwed to the side wall of the air conditioner, and the other side is connected to the electric heater. Although the current electric heating installation method can meet the installation requirements of the electric heater on the air conditioner and provides convenience for after-sales maintenance, during the transportation of the air conditioner, the external impact force will be directly transmitted from the mounting plate to the electric heater, causing a direct impact on the electric heating. At the same time, the mounting plate and the electric heating card are not firmly connected, which makes it easy for the electric heater to be relatively displaced when it is impacted, resulting in damage to the electric heating part. In particular, the heating wire of the electric heater is prone to breakage during transportation. Therefore, how to solve the problem that the electric heater is easy to break during transportation becomes a difficult problem. Utility Model Content

[0027] like Figure 1As shown, an air-conditioning electric heating installation and protection structure comprises an air-conditioning, an electric heater 1 and two installation plates 2, the electric heater 1 comprises a heating wire and an outer shell, a hollow portion is provided in the middle of the outer shell and openings connecting the hollow portion are provided on opposite sides, the heating wire is fixedly arranged in the hollow portion of the outer shell, the electric heater 1 is horizontally arranged inside the air-conditioning, opposite installation plates 2 are fixedly installed on the two side surfaces in the axial direction of the electric heater 1, the opposite installation plates 2 are both bolted to one side wall of the air-conditioning, and it is characterized in that it also comprises a protection groove 3 and an anti-vibration connector 4, the outer shell surface of the electric heater 1 is sleeved with a protection groove 3, the two sides of the protection groove 3 in the length direction are bolted to the opposite installation plates 2, the side wall edge of the protection groove 3 extends along one side of the electric heater 1 perpendicular to the axial direction to the edge of the opening, an anti-vibration connector 4 is provided on the side edge of the top of the installation plate 2, and the anti-vibration connector 4 is bolted to the top plate of the air-conditioning.

[0028] like Figure 1 As shown, the anti-vibration connector 4 is directly attached to the top of the inner surface of the air conditioner and connected by bolts, which significantly enhances the connection strength between the air conditioner electric heating 1 component and the air conditioner body, effectively absorbs and alleviates the vibration generated during operation, and protects the electric heating 1 from breaking during the transportation of the air conditioner.

[0029] The side wall edge of the protective groove 3 extends along one side of the electric heater 1 perpendicular to the axial direction to the edge of the opening, which means that the side wall of the protective groove 3 is close to the outer shell of the electric heater 1 and does not block the opening, and is bolted to the relative mounting plate 2 on both sides in its length direction, thereby increasing the rigidity of the overall structure, ensuring the stability of the electric heater 1 component, especially inside the electric heating wire air conditioner, avoiding displacement or damage caused by vibration, and at the same time avoiding direct blocking of the heating wire, thereby ensuring effective conduction and dissipation of heat.

[0030] Furthermore, the anti-vibration connector 4 is a flange of the mounting plate 2, which extends along the side edge of the top of the mounting plate 2 to the top of the inner surface of the air conditioner and fits with the top of the inner surface of the air conditioner.

[0031] In the present solution, the anti-vibration connector 4 may also be an L-shaped connector, but considering that the rigid connection between the anti-vibration connector 4 and the mounting plate 2 is difficult to design and the production cost of the assembly, it is preferably designed as a flanged form of the mounting plate 2, which not only provides a tight connection and saves costs, but also fits tightly with the inner surface of the air conditioner, significantly enhancing the vibration resistance of the entire electric heating structure.

[0032] Furthermore, the relative mounting plate 2 includes a first mounting plate and a second mounting plate, a hook is provided on a side of the first mounting plate close to the electric heater 1, a slot is provided on a side in the axial direction of the electric heater 1, the hook of the first mounting plate cooperates with the slot of the electric heater 1, a wiring harness is provided on a side of the electric heater 1 close to the first mounting plate, a wiring harness hole is provided at the cooperation position between the first mounting plate and the electric heater 1, the wiring harness extends through the wiring harness hole in a direction away from the electric heater 1, and the second mounting plate is bolted to the electric heater 1.

[0033] The harness hole set on the first mounting plate provides a special threading channel for the harness of the electric heating 1 component, which not only makes the harness layout more neat and orderly, avoids the disorderly accumulation of the harness in a small space, reduces the risk of wear and short circuit, but also facilitates the subsequent maintenance and inspection, and improves the maintainability of the system.

[0034] Furthermore, there are two protective grooves 3 , and the two protective grooves 3 include a lower protective groove 31 and an upper protective groove 32 . The lower protective groove 31 and the upper protective groove 32 are positioned opposite to each other and the groove openings face the electric heater 1 .

[0035] In this solution, one protection groove 3 may also be provided, but the protection effect is not good enough, so it is preferred to provide two protection grooves 3.

[0036] Furthermore, the mounting plate 2 is made of sheet metal material.

[0037] Using sheet metal material as the mounting plate 2 is not only cost-effective and easy to process, but also has good mechanical strength and corrosion resistance, thereby ensuring the long-term stability and reliability of the entire protective structure in a complex air-conditioning working environment.

[0038] like Figure 2 , Figure 3 As shown, there are two anti-vibration connectors 4 , and an anti-vibration connector 4 is provided on the side edge of the top of each mounting plate 2 .

[0039] The configuration of two anti-vibration connectors 4 ensures that each mounting plate 2 can be independently and evenly firmly connected to the top plate of the air conditioner, further improving the anti-vibration performance of the entire electric heating module 1 and ensuring the stability and reliability of long-term operation.

[0040] The above implementation modes are only preferred implementation modes of the present utility model and do not limit the protection scope of the present utility model.
