Description

Technical Field

[0001] This utility model relates to the field of air conditioner or heat pump maintenance technology, and more specifically, to an air outlet device. Background Technology

[0002] Currently, domestically manufactured heat pump air outlets or air conditioning vents are all fixed and hidden in the ceiling. The existing structure presents a problem of difficulty in disassembly and assembly when the air outlet malfunctions and needs to be repaired or replaced: if you want to remove the old air outlet or replace the parts, you have to remove the roof to do so. Therefore, it is inconvenient for the maintenance and after-sales service of heat pumps or air conditioners, resulting in increased maintenance costs.

[0003] A Chinese patent discloses a central air conditioning vent that is easy to clean, comprising an air vent and an air conditioning housing. Symmetrical limiting protrusions are provided on both sides of the air vent. Fixing plates extend outward from both sides of the air conditioning housing, and first support seats are provided at both ends of the fixing plates. Guide rollers are rotatably connected to the top of the first support seats. A transmission mechanism for controlling the raising and lowering of the air vent is provided between the fixing plates and the limiting protrusions. This design allows the air vent to be lowered for wiping and cleaning, but the remaining components of the air conditioner are still hidden in the ceiling, making air conditioner maintenance inconvenient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an air outlet device that can intelligently move up and down, making it easy to disassemble and install, reducing the difficulty of repairing heat pumps or air conditioners, improving repair efficiency, and reducing repair costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An air outlet device is provided, including a fixed frame, a mounting base, and a lifting mechanism. One end of the lifting mechanism is connected to the fixed frame, and the other end is connected to the mounting base. The mounting base can also be detachably connected to the fixed frame. An air cavity is provided in the mounting base, and a fan wheel and fins are installed in the air cavity. The mounting base has an air inlet and an air outlet, both of which are connected to the air cavity. The fan wheel is located near the air inlet, and the fins are located near the air outlet.

[0007] This utility model's air outlet device is applied in heat pumps or air conditioners. The impeller, also known as a fan or blower, primarily functions to circulate air. The impeller generates airflow through rotation, drawing indoor air into the air conditioner or heat pump. After cooling or heating, the air is blown out, thus achieving indoor air circulation. The fins, also called heat sinks or evaporator fins, are a crucial component of the refrigeration system. The main functions of the fins include: ① Increasing the heat exchange area: By increasing the surface area, the fins improve the heat exchange efficiency between the refrigerant and the air. ② Accelerating heat exchange: The presence of fins disrupts the air boundary layer, allowing for more efficient airflow and accelerating the heat exchange process. ③ Evaporation and condensation of the refrigerant: As the impeller blows air towards the fins, the fins condense the refrigerant, resulting in lower temperatures of the air exiting the outlet, thus improving the cooling effect. This invention integrates the wind turbine and fins into the mounting base. The mounting base and the fixed frame are connected by a lifting mechanism, allowing the mounting base to move up and down relative to the fixed frame. This allows the mounting base to be lowered when maintenance or replacement of parts is needed, enabling maintenance without disassembling the roof. This reduces maintenance difficulty, improves maintenance efficiency, and also reduces maintenance costs.

[0008] Furthermore, the lifting mechanism includes a driving component, a first transmission component, and a second transmission component. The first transmission component is mounted on the fixed frame, and the driving component and the second transmission component are mounted on the mounting base. The driving component is also connected to the second transmission component, and the first transmission component and the second transmission component cooperate to perform transmission. The driving component drives the second transmission component to move, and the lifting mechanism achieves lifting movement through the cooperation of the second transmission component and the first transmission component, thereby causing the mounting base to move up and down relative to the fixed frame.

[0009] Furthermore, the first transmission component is a rack, which is partially inserted into the mounting base. The second transmission component is a gear, and the driving component is a motor. The gear is mounted on the output shaft of the motor and meshes with the rack. The mounting base has a socket into which the rack can be inserted. The motor drives the gear to rotate and mesh with the rack, allowing the mounting base to move up and down relative to the fixed frame, thereby facilitating the disassembly and replacement of components within the mounting base.

[0010] Furthermore, it also includes a slider and a slide rail. The top of the slider is connected to the fixed frame, the rack is mounted on the outside of the slider, and the slide rail is connected to the mounting base. The slider is also inserted into the slide rail and slidably connected thereto. The sliding connection between the slider and the slide rail can play a certain guiding role. The motor drives the gear to rotate to mesh with the rack, and the rack drives the slider to slide smoothly with the slide rail, thereby making the mounting base move up and down more smoothly relative to the fixed frame.

[0011] Furthermore, the first transmission component is a nut, the second transmission component is a screw, and the driving component is a motor. The screw is mounted on the output shaft of the motor and is threadedly connected to the nut. By fixing the nut to the mounting bracket, a screw-nut transmission pair is formed between the screw and the nut. The motor drives the screw to rotate, which is then converted into linear motion of the screw, causing the mounting base to move up and down relative to the mounting bracket.

[0012] Furthermore, the lifting mechanism is a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The lifting mechanism includes a fixed part and a movable part. One of the fixed part and the movable part is connected to the fixed frame, and the other is connected to the mounting base. The hydraulic cylinder, pneumatic cylinder, or electric cylinder is a telescopic mechanism employing different driving methods, thereby enabling the mounting base to move up and down relative to the fixed frame.

[0013] Furthermore, it also includes a guide assembly, which comprises a first guide portion and a second guide portion that are interlocked with each other. The first guide portion is connected to the fixing frame, and the second guide portion is connected to the mounting base. Preferably, multiple sets of guide assemblies are provided, each located on both sides of the mounting base. Through the interlocking cooperation of the first guide portion and the second guide portion, guidance is achieved during the relative movement of the mounting base and the fixing frame, thereby improving the accuracy of their docking.

[0014] Furthermore, the impeller and the fins are arranged parallel to each other, and both the impeller and the fins are positioned across the length of the air outlet. The length of both the impeller and the fins is greater than or equal to the length of the air outlet, which can increase the wind speed and air volume, and improve the heat exchange effect.

[0015] Furthermore, both the air inlet and the air outlet are located on the side of the mounting base and face each other, or the air outlet is located at the bottom of the mounting base and the air inlet is located on the side of the mounting base. This utility model is applicable to both bottom-outlet and side-outlet air outlet methods, and can cover the air outlet devices of most centrally controlled heat pumps or air conditioners used indoors.

[0016] Furthermore, it also includes limit switches and a control system. The limit switches are installed on the lifting mechanism, and both the limit switches and the lifting mechanism are communicatively connected to the control system. The limit switches intelligently detect the vertical movement; upon reaching the set travel distance, an alarm is automatically triggered and the mechanism locks; this prevents malfunctions such as the mounting bracket overtraveling or failing to descend fully before stopping; it can detect whether the travel distance is complete; if not, a fault command is issued; the mechanism returns to the reset point for further detection; and then a decision is made regarding whether to descend or ascend.

[0017] Furthermore, a grille is provided at the air outlet. The grille provides protection for the air outlet, thereby protecting the components inside the mounting bracket.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention integrates the wind turbine and fins into the mounting base. The mounting base and the fixed frame are connected by a lifting mechanism, allowing the mounting base to move up and down relative to the fixed frame. This allows the mounting base to be lowered when maintenance or replacement of parts is needed, enabling maintenance without disassembling the roof. This reduces maintenance difficulty, improves maintenance efficiency, and also reduces maintenance costs. Attached Figure Description
