Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and in particular to a ceiling-mounted air handling unit. Background Technology

[0002] A ceiling-mounted air conditioner is a type of air conditioner that is recessed into the ceiling to reduce space usage. It uses air outlets on its surface for heat exchange. Due to the limited location of the air outlets, it can only blow air in a set direction and cannot blow air horizontally when cooling.

[0003] To improve the aesthetics of the auger by changing the gas flow direction and closing the air outlet, a guide plate is installed at the air outlet. The opening and closing of the air outlet and the switching of the guide plate angle are achieved by rotating the guide plate. In the existing technology, the guide plate is usually designed as a long and thin rectangle. This inevitably causes the middle section of the guide plate to tend to sag due to gravity after the unit is hoisted. Moreover, the guide plate may also deform and sag in the middle section due to deformation and tolerance during the manufacturing process, resulting in obvious gaps on the auger and seriously affecting its aesthetics. Summary of the Invention

[0004] To address the technical problem of sagging in the middle section of the air guide plate in existing technologies, which affects the aesthetics of the ceiling machine, a ceiling machine is provided that utilizes a support structure to support the air guide plate to improve its aesthetics.

[0006] The main frame, on which a first air outlet is provided;

[0007] An air guide plate is movably disposed at the first air outlet;

[0008] A drive mechanism is provided on the main frame, and the drive mechanism is capable of driving the air guide plate to move into the main frame to open the first air outlet;

[0009] A first support structure is provided at the first air outlet. When the air guide plate closes the first air outlet, the air guide plate overlaps the first support structure.

[0010] An avoidance groove is provided at the edge of the first air outlet, and the avoidance groove constitutes the first support structure. When the air guide plate closes the first air outlet, the edge of the air guide plate is located in the avoidance groove.

[0011] The air guide plate is provided with an overlap edge, which is located within the clearance groove when the air guide plate closes the first air outlet.

[0012] The main frame is provided with a first guide structure, and the air guide plate is provided with a second guide structure. The first guide structure and the second guide structure are guided and cooperated, and the guiding cooperation direction of the first guide structure and the second guide structure has an angle with the moving direction of the air guide plate driven by the driving mechanism.

[0013] The hoist also includes a crank, one end of which is connected to the drive mechanism, and the other end of which is hinged to the air guide plate. The hinge position of the crank and the air guide plate is spaced apart from the second guide structure.

[0014] Along the length of the air guide plate, the air guide plate has two opposing first edges, and at least one of the first edges is provided with a second guide structure, with the first guide structure and the second guide structure corresponding one-to-one.

[0015] The ceiling machine also includes a reinforcing member installed between the two first edges. One end of the reinforcing member is connected to one of the first edges, and the other end of the reinforcing member is connected to the other first edge.

[0016] The main frame is provided with a sliding groove, and the air guide plate is provided with a slider. The slider is movably disposed in the sliding groove, the sliding groove constitutes the first guide structure, and the slider constitutes the second guide structure; or, the air guide plate is provided with a rolling element, the rolling element is rotatably disposed in the sliding groove, the sliding groove constitutes the first guide structure, and the rolling element constitutes the second guide structure.

[0017] The ceiling fan also includes an air outlet assembly, which is vertically and flexibly mounted on the main frame. The air outlet assembly forms a second air outlet with the main frame by descending. The first air outlet is formed on the air outlet assembly, and the air guide plate is movably mounted on the air outlet assembly.

[0018] The air outlet assembly includes an air outlet frame, and a second air outlet is formed between the air outlet frame and the main frame. The air outlet frame can be raised and lowered independently.

[0019] The air outlet assembly includes an air outlet frame and a return air panel. An air outlet is formed between the air outlet frame and the main frame. The return air panel is provided with a return air outlet. The air outlet frame and the return air panel are connected and rise and fall together.

[0020] The ceiling fan provided by this invention features a support structure at the first air outlet to support the air guide plate, thereby preventing deformation of the air guide plate under gravity, ensuring reliable movement of the air guide plate, and effectively improving the aesthetics of the ceiling fan. Furthermore, the air guide plate, under gravity, tightly presses against the first support structure, improving the sealing effect of the air guide plate on the first air outlet. Simultaneously, the air guide plate is designed to move inwards into the ceiling fan, preventing interference with the support structure during movement and ensuring the reliability of the ceiling fan.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0030] like Figures 1 to 6The ceiling fan shown includes: a main frame 1, on which a first air outlet 11 is provided; an air guide plate 2, which is movably disposed at the first air outlet 11; a drive mechanism 3, which is disposed on the main frame 1 and can drive the air guide plate 2 to move into the main frame 1 to open the first air outlet 11; a first support structure is provided at the first air outlet 11, and when the air guide plate 2 closes the first air outlet 11, the air guide plate 2 overlaps the first support structure. A support structure is set at the first air outlet 11 to support the air guide plate 2, thereby avoiding deformation of the air guide plate 2 under the influence of gravity, ensuring reliable movement of the air guide plate 2, effectively improving the aesthetics of the ceiling machine. Moreover, the air guide plate 2 will tightly squeeze the first support structure under the action of gravity, thereby improving the sealing effect of the air guide plate 2 on the first air outlet 11. At the same time, the air guide plate 2 is set to move into the interior of the ceiling machine, and the air guide plate 2 will not interfere with the support structure during the movement, ensuring the reliability of the ceiling machine.

[0031] In one implementation, a clearance groove 12 is provided at the edge of the first air outlet 11. The clearance groove 12 constitutes the first support structure. When the air guide plate 2 closes the first air outlet 11, the edge of the air guide plate 2 is located within the clearance groove 12. The air guide plate 2 overlaps the inner wall of the clearance groove 12, and the clearance groove 12 supports the air guide plate 2, so that the edge of the air guide plate 2 can be reliably supported, avoiding deformation of the air guide plate 2 due to gravity, ensuring reliable sealing of the first air outlet 11 by the air guide plate 2, and at the same time, the air guide plate 2 will not cause structural interference with the first air outlet 11 due to deformation during movement, ensuring reliable movement of the air guide plate 2.

[0032] To ensure that the clearance groove 12 provides support for the air guide plate 2, a groove is cut into the edge of the first air outlet 11 facing the interior of the ceiling machine to form the clearance groove 12. This ensures that when the air guide plate 2 opens towards the interior of the ceiling machine, it will not interfere with the edge of the first air outlet 11, thus guaranteeing the reliable operation of the air guide plate 2. Furthermore, because the clearance groove 12 faces the interior of the ceiling machine, when the air guide plate 2 closes the first air outlet 11, the fitting gap between the air guide plate 2 and the first air outlet 11 is located within the clearance groove 12. Users below the ceiling machine cannot directly observe this fitting gap, further improving the aesthetics of the ceiling machine.

[0033] The length of the clearance groove 12 is the same as the length of the air guide plate 2, which can support the entire air guide plate 2, thereby preventing the middle part of the air guide plate 2 from being affected by gravity and causing it to sag or deform, thus ensuring the structural reliability of the air guide plate 2.

[0034] The air guide plate 2 is provided with an overlap 21. When the air guide plate 2 closes the first air outlet 11, the overlap 21 is located within the clearance groove 12. The thickness of the overlap 21 is less than the thickness of the air guide plate 2, so that when the air guide plate 2 closes the first air outlet 11, the side of the air guide plate 2 facing the ground can be on the same plane as the side of the ceiling machine facing the ground, making the surface of the ceiling machine smooth and further improving its aesthetics. At the same time, the cooperation between the overlap 21 and the clearance groove 12 can form a stepped structure at the cooperation position between the air guide plate 2 and the first air outlet 11, effectively increasing the sealing effect between the air guide plate 2 and the first air outlet 11.

[0035] In order to prevent the air guide plate 2 from interfering with the first air outlet 11 during the movement of the air guide plate 2, a slope is provided on the overlap 21. The slope is used to avoid the first air outlet 11. Therefore, only a very small assembly gap is needed to ensure the smooth movement of the air guide plate 2.

[0036] Since the air guide plate 2 not only needs to close the first air outlet 11, but also needs to guide the airflow while opening the first air outlet 11, it needs to be tilted to a certain extent to change the direction of the airflow and play a guiding role. For this purpose, the main frame 1 is provided with a first guide structure 13, and the air guide plate 2 is provided with a second guide structure 22. The first guide structure 13 and the second guide structure 22 are guided and cooperate, and the guiding cooperation direction of the first guide structure 13 and the second guide structure 22 forms an angle with the direction of movement of the air guide plate 2 driven by the driving mechanism 3. While the driving mechanism 3 drives the air guide plate 2 to move along the first direction, the first guide structure 13 and the second guide structure 22 restrict the movement of the air guide plate 2 along the second direction. At this time, the air guide plate 2 will move obliquely along the combined direction of the first and second directions. During this process, the air guide plate 2 gradually tilts, thereby achieving the purpose of changing the direction of the airflow.

[0037] To enable the movement of the air guide plate 2, the ceiling machine also includes a crank 5. One end of the crank 5 is connected to the drive mechanism 3, and the other end of the crank 5 is hinged to the air guide plate 2. There is a gap between the hinge position of the crank 5 and the air guide plate 2 and the second guide structure 22. The crank 5 adjusts the rotation of the drive mechanism 3 to linear movement of the air guide plate 2, forcing the second guide structure 22 to move within the first guide structure 13, thereby adjusting the tilt angle of the air guide plate 2. Simultaneously, by setting the gap, the linear movement of the air guide plate 2 driven by the crank 5 and the linear movement of the air guide plate 2 restricted by the second guide structure 22 are not at the same point, allowing the two linear movements to be combined, ensuring reliable movement of the air guide plate 2.

[0038] Among them, the drive mechanism 3 can be a motor, and one end of the crank 5 is set on the output shaft of the motor, and the output shaft can drive the crank 5 to rotate.

[0039] Preferably, the air guide plate 2 is provided with a bracket, the lower end of the bracket is provided on the air guide plate 2, and the crank 5 is hinged to the upper end of the bracket, thereby maximizing the spacing and effectively ensuring the movement of the air guide plate 2.

[0040] Along the length of the air guide plate 2, the air guide plate 2 has two opposing first edges, and at least one of the first edges is provided with a second guide structure 22. The first guide structure 13 and the second guide structure 22 correspond one-to-one. By placing the second guide structure 22 on the first edge, the reliable movement of the air guide plate 2 can be ensured, and the cooperation between the first guide structure 13 and the second guide structure 22 can also be avoided from affecting the air volume of the first air outlet 11.

[0041] Preferably, the second guide structure 22 is provided on both of the first edges. The movement of the air guide plate 2 is guided at both ends in the length direction of the air guide plate 2, ensuring the reliable movement of the air guide plate 2, and at the same time increasing the support effect of the air guide plate 2, so as to ensure the structural reliability of the air guide plate 2 as much as possible.

[0042] The drive mechanism 3 is located on one side of the guide plate 2 along its length, meaning it is only connected to one end of the guide plate 2. To reliably transmit the driving force of the drive mechanism 3 to the other end of the guide plate 2, the ceiling fan also includes a reinforcing member 4. This reinforcing member 4 is installed between the two first edges, with one end connected to one of the first edges and the other end connected to the other. The driving force of the drive mechanism 3 is transmitted through the reinforcing member 4, allowing the two first edges to move synchronously and further ensuring the reliable movement of the guide plate 2.

[0043] Preferably, the reinforcing member 4 includes a steel shaft, the end of which is fixed to the first edge by screws. The steel shaft can reliably transmit the driving force of the drive mechanism 3. At the same time, the structural strength of the steel shaft prevents the air guide plate 2 from deforming due to gravity, further ensuring the structural reliability of the air guide plate 2.

[0044] The main frame 1 is provided with a sliding groove, and the air guide plate 2 is provided with a slider. The slider is movably disposed within the sliding groove. The sliding groove constitutes the first guide structure 13, and the slider constitutes the second guide structure 22. When the air guide plate 2 moves, the slider moves within the sliding groove under the drive of the air guide plate 2. The sliding groove restricts the movement of the air guide plate 2 by limiting the movement of the slider.

[0045] To reduce frictional losses between the second guide structure 22 and the first guide structure 13, a rolling element is provided on the air guide plate 2. The rolling element is rotatably disposed within the slide groove, which constitutes the first guide structure 13, and the rolling element constitutes the second guide structure 22. In this case, a rolling engagement is formed between the rolling element and the slide groove, reducing the driving force requirement on the drive mechanism 3.

[0046] As shown in the figure, the second guide structure 22 and the first guide structure 13 move horizontally, that is, the slide is parallel to the horizontal plane, while the crank 5 drives the air guide plate 2 to move vertically. With the cooperation of the two, the air guide plate 2 can be tilted.

[0047] The ceiling-mounted air conditioner also includes an air outlet assembly, which is vertically and flexibly mounted on the main frame 1. The air outlet assembly, by descending, forms a second air outlet with the main frame 1. The air outlet assembly has a first air outlet 11 formed on it, and the air guide plate 2 is movably mounted on the air outlet assembly. The main frame 1 is fixedly mounted on the outer circumference of the air outlet assembly. When the ceiling-mounted air conditioner is operating, the air outlet assembly descends to a certain height, creating a height difference with the main frame 1. The air outlet assembly and the main frame 1, located outside the air outlet assembly, form a second air outlet. The fan blows air from inside the ceiling-mounted air conditioner through the air outlet. When the air conditioner is in cooling mode, the air outlet can be made as parallel to the horizontal plane as possible to increase the air delivery distance, thereby achieving waterfall-style cooling and improving user comfort.

[0048] The main frame 1 is equipped with an air supply duct. When the air outlet component descends, the air guide plate 2 moves precisely between the air supply duct and the first air outlet 11, which can reliably guide the airflow of the air supply duct to the first air outlet 11, thereby improving the air outlet effect of the ceiling machine.

[0049] The ceiling fan has a cooling mode. When the ceiling fan is in cooling mode, the air outlet assembly descends to open the second air outlet, and the air guide plate 2 opens the first air outlet 11. At this time, the cold air from the ceiling fan can be partially blown out horizontally to achieve waterfall-style cooling, while the remaining part is discharged obliquely downwards to increase the cooling effect on the room.

[0050] To further increase the airflow from the first air outlet 11, when the ceiling fan is in the cooling mode, the air guide plate 2 forms an angle with the plane containing the first air outlet 11. Rotating the air guide plate 2 increases the airflow from the first air outlet 11, thereby improving the cooling effect.

[0051] Alternatively, when the ceiling unit is in cooling mode, only the air guide plate 2 opens the first air outlet 11. The cold air from the ceiling unit is blown out only through the first air outlet 11, which can quickly cool the lower part of the room, thereby improving the cooling effect of the room.

[0052] The ceiling fan also has a heating mode. When the ceiling fan is in heating mode, the air outlet component can be lowered to open the second air outlet, and at the same time the air guide plate 2 opens the first air outlet 11. At this time, the ceiling fan can heat with the maximum air volume, thereby improving the heating efficiency of the ceiling fan.

[0053] Alternatively, when the ceiling fan is in heating mode, only the air guide plate 2 opens the first air outlet 11. At this time, the air from the ceiling fan is quickly blown downward through the first air outlet 11, thereby achieving the purpose of rapid heating.

[0054] The air outlet assembly includes an air outlet frame, with a second air outlet formed between the air outlet frame and the main frame 1. The air outlet frame can be raised and lowered independently. In other embodiments not shown, the air outlet assembly includes an air outlet frame and a return air panel, with a second air outlet formed between the air outlet frame and the main frame 1. The return air panel is provided with a return air outlet, and the air outlet frame and the return air panel are connected and can be raised and lowered together.

[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
