Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, specifically to a damper installation structure for a fresh air module and an air conditioner. Background Technology

[0002] With the development of air conditioning technology, people have higher and higher requirements for indoor air quality. Traditional air conditioners are insufficient in terms of ventilation function, so the introduction of fresh air modules has become a trend.

[0003] Existing fresh air modules typically include multiple dampers, such as anti-backflow dampers, fresh air dampers, and exhaust reversing dampers. These dampers are all driven by stepper motors to achieve their opening and closing functions. However, the output shaft of a stepper motor is generally a flat shaft, which means that when assembling it with the damper, the flat shaft needs to be constantly rotated to adjust its position so that it can be smoothly inserted into the flat slot on the damper. This operation is cumbersome and affects assembly efficiency. In addition, since the damper is generally located inside the fresh air module, the installer cannot visually see the relative position of the damper and the stepper motor output shaft when installing the stepper motor, which further increases the difficulty of assembling the stepper motor output shaft with the damper. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a damper installation structure for a fresh air module and an air conditioner, so as to solve the problems of difficult assembly, complicated operation and low assembly efficiency of dampers and stepper motors in the existing fresh air modules.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A damper mounting structure for a fresh air module, comprising:

[0007] A damper bracket has an air vent on one side, and a damper is rotatably installed inside the air vent. The damper is arranged vertically, and a flat slot is provided on the upper part of the side where the damper is rotatably connected to the air vent.

[0008] A stepper motor, detachably mounted on a damper bracket, wherein the power output shaft of the stepper motor is a flat shaft, which is inserted into a flat slot; and

[0009] A pre-adjustment assembly is mounted on the damper bracket and arranged on the same side as the air outlet. The pre-adjustment assembly includes a positioning component and a limiting component. The positioning component is used to insert a flat shaft, and the limiting component is used to limit the rotation angle of the stepper motor.

[0010] During assembly, insert the flat shaft into the positioning component and rotate the stepper motor to abut against the limiting component to adjust the insertion angle of the flat shaft when installing the stepper motor.

[0011] Compared with the prior art, this utility model has the following beneficial effects: In use, since the damper is in the open state in the initial state, before assembling the stepper motor, the flat shaft of the stepper motor is first inserted into the positioning part, and the stepper motor is rotated to abut against the limiting part, thereby adjusting the angle of the flat shaft of the stepper motor. Then, the stepper motor is removed and assembled with the damper bracket. At this time, the flat shaft of the stepper motor can be directly inserted into the flat slot of the damper without adjustment. While making the operation simple and convenient, it improves the installation efficiency of the stepper motor and reduces the assembly difficulty of the flat shaft and the flat slot.

[0012] Preferably, the positioning element includes a shaft hole formed on the damper bracket, the shaft hole being used for flat shaft insertion and locking, and the limiting element being located on one side of the shaft hole.

[0013] Preferably, the limiting component includes a limiting plate fixedly installed on the damper bracket, and the limiting plate is located on the rotation trajectory of the stepper motor.

[0014] Preferably, the device further includes a motor mounting assembly, which includes a fitting mounted on a damper bracket and a mounting component detachably engaged with the fitting. The fitting is located above the air outlet, and the mounting component is fixedly connected to the stepper motor.

[0015] Preferably, the mounting component includes a mounting cover for housing a stepper motor and two connecting ears fixedly connected to the mounting cover. The opening end of the mounting cover is arranged facing the air vent, and the two connecting ears are respectively located on both sides of the mounting cover. The two connecting ears are detachably connected to the mounting component.

[0016] Preferably, the assembly includes two mounting brackets that are vertically and fixedly installed on the damper bracket. Each mounting bracket has a screw post fixedly installed on its top, and each connecting lug has a first screw hole. The two connecting lugs are fixed by two screws that pass freely through the two first screw holes and are threadedly connected to the two screw posts.

[0017] Preferably, each of the mounting brackets has a hook fixedly installed on the side wall away from the damper bracket, and each of the connecting ears has a slot on the side facing the opening end of the mounting cover. The slots of the two connecting ears are used to engage with the hooks on the two mounting brackets one by one.

[0018] Preferably, two symmetrically arranged second screw holes are provided on the side wall of the opening end of the mounting cover, and the stepper motor is threadedly connected to the two second screw holes one-to-one by two screws.

[0019] Preferably, the mounting cover has a wire groove on its open end.

[0020] This utility model also provides an air conditioner, including the damper mounting structure of the fresh air module.

[0021] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0029] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] like Figure 1-4 as well as Figure 6As shown, an embodiment of this utility model provides a damper installation structure for a fresh air module, including: a damper bracket 1, with an air outlet 11 on one side, a damper 2 rotatably installed inside the air outlet 11, the damper 2 being vertically arranged, and a flat slot 22 being provided on the upper part of the side of the damper 2 rotatably connected to the air outlet 11; a stepper motor 5, detachably mounted on the damper bracket 1, the power output shaft of the stepper motor 5 being a flat shaft, the flat shaft being inserted into the flat slot 22; and a pre-adjustment component, mounted on the damper bracket 1 and arranged on the same side as the air outlet 11, the pre-adjustment component including a positioning component and a limiting component, the positioning component being used to insert the flat shaft, and the limiting component being used to limit the rotation angle of the stepper motor 5; wherein the damper 2 and the air outlet 11 are rotatably connected via a rotating shaft 21, and the flat slot 22 is located at the upper end of the rotating shaft 21.

[0031] Since the initial state of the damper 2 is open, the positional relationship between the positioning component and the limiting component is determined based on the state of the flat shaft and the flat slot 22 when the damper 2 is open. This allows the flat shaft of the stepper motor 5 to be inserted into the positioning component and rotated to abut against the limiting component, so that the angle of the flat shaft can be adjusted to the angle when the flat shaft and the flat slot 22 are engaged when the damper 2 is open. Thus, when assembling the stepper motor 5, the flat shaft can be directly and quickly inserted into the flat slot 22 of the damper 2 without adjusting the angle.

[0032] like Figure 1-2 as well as Figure 6 As shown, according to another embodiment of the present invention, the damper installation structure of the fresh air module is further optimized in terms of its positioning component and limiting component. The positioning component includes a shaft hole 12 opened on the damper bracket 1, the shaft hole 12 is used for flat shaft insertion and locking, and the limiting component is located on one side of the shaft hole 12.

[0033] The limiting component includes a limiting plate 13 fixedly installed on the damper bracket 1, and the limiting plate 13 is located on the rotation trajectory of the stepper motor 5.

[0034] By locking the flat shaft into the shaft hole 12, and then rotating the stepper motor 5 to abut against the limit plate 13, the angle of the flat shaft is adjusted to ensure that the flat shaft can be quickly inserted into the flat slot 22 when assembling the stepper motor 5.

[0035] like Figure 1-2 as well as Figure 5-6 As shown, according to another embodiment of the present utility model, the damper mounting structure of the fresh air module preferably further includes a motor mounting assembly. The motor mounting assembly includes a fitting mounted on the damper bracket 1 and a mounting component detachably engaged with the fitting. The fitting is located above the air outlet 11, and the mounting component is fixedly connected to the stepper motor 5.

[0036] The mounting component includes a mounting cover 4 for housing the stepper motor 5 and two connecting ears 41 fixedly connected to the mounting cover 4. The open end of the mounting cover 4 faces the air vent 11, and the two connecting ears 41 are located on both sides of the mounting cover 4. The two connecting ears 41 are detachably connected to the mounting component. Preferably, two symmetrically arranged second screw holes 44 are provided on the side wall of the open end of the mounting cover 4. The stepper motor 5 is threadedly connected to the two second screw holes 44 one-to-one by two screws. During assembly, the stepper motor is... 5. Insert the stepper motor 5 into the mounting cover 4, and then connect it to the two second screw holes 44 with two screws to fix the stepper motor 5. At this time, the pre-adjustment of the flat shaft is carried out after the stepper motor 5 is installed in the mounting cover 4. The specific steps are still to first insert the flat shaft into the shaft hole 12 and lock it, and then rotate the mounting cover 4 to drive the stepper motor 5 inside to rotate synchronously, so that one of the connecting ears 41 abuts against the limiting plate 13. The position of the limiting plate 13 will be adjusted according to the rotation trajectory of the mounting cover 4 and the two connecting ears 41.

[0037] The assembly includes two mounting brackets 3 vertically facing each other and fixedly mounted on the damper bracket 1. Each mounting bracket 3 has a screw post 32 fixedly mounted on its top. Each connecting lug 41 has a first screw hole 42. The two connecting lugs 41 are fixed by two screws passing through the two first screw holes 42 one by one. During assembly, the first screw holes 42 on the two connecting lugs 41 are aligned with the screw posts 32 on the two mounting brackets 3, and then the screws are threadedly connected to the screw posts 32 to fix the two connecting lugs 41 and fix the position of the mounting cover 4.

[0038] like Figure 1-2 as well as Figure 5-6 As shown, according to another embodiment of the present invention, the damper installation structure of the fresh air module is preferably provided with hooks 31 fixedly installed on the side wall of each mounting bracket 3 away from the damper bracket 1, and slots 43 are provided on the side of each connecting ear 41 facing the opening end of the mounting cover 4. The slots 43 of the two connecting ears 41 are used to engage with the hooks 31 on the two mounting brackets 3 in a one-to-one correspondence. Through the engagement of the two slots 43 with the two hooks 31, the installation of the mounting cover 4 is made more stable.

[0039] like Figure 1-2 as well as Figure 5 As shown, according to another embodiment of the present invention, the damper mounting structure of the fresh air module preferably has a wire groove 45 provided on the open end of the mounting cover 4 to facilitate the routing of the wiring connected to the stepper motor 5.

[0040] This utility model also provides an air conditioner, including the damper mounting structure of the fresh air module. Through the damper mounting structure of the fresh air module, the stepper motor 5 can be quickly disassembled and assembled, improving efficiency.

[0041] The working principle of this utility model is as follows: When using this utility model, firstly, the stepper motor 5 is installed into the mounting cover 4, and then the stepper motor 5 is fixed by connecting two screws to the two second screw holes 44. Then, the flat shaft is inserted into the shaft hole 12 and locked. Then, the mounting cover 4 is rotated to drive the stepper motor 5 inside to rotate synchronously, so that one of the connecting ears 41 abuts against the limiting plate 13, thereby completing the adjustment of the insertion angle of the flat shaft. Then, the mounting cover 4 is removed, so that the flat shaft is separated from the shaft hole 12. Then, the flat shaft is inserted into the damper bracket 1 and engaged with the flat slot 22. At the same time, the two slots 43 on the two connecting ears 41 are engaged with the two hooks 31 one by one, and the two connecting ears 41 are fixed by connecting two screws to the two screw posts 32 one by one, thereby completing the fixation of the mounting cover 4.
