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] In existing technologies, in order to change the direction of gas flow and close the air outlet to improve the aesthetics of the ceiling fan, 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. However, in order to ensure the reliable rotation of the guide plate, a rotation gap needs to be reserved between the guide plate and the edge of the air outlet. This rotation gap will cause obvious gaps on the ceiling fan when the air outlet is closed, which seriously affects the aesthetics of the ceiling fan. Summary of the Invention

[0004] In order to solve the technical problem that the rotation gap of the reserved air guide plate in the prior art affects the aesthetics of the ceiling machine, a ceiling machine is provided that sets a first lifting mechanism so that the air guide plate descends first and then rotates, so that there is no need to reserve a rotation gap.

[0005] A ceiling machine, comprising:

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

[0007] An air guide plate assembly is movably disposed at the first air outlet via a driving structure;

[0008] The drive structure includes a first lifting mechanism and a rotating mechanism. The first lifting mechanism is disposed on the main frame, the rotating mechanism is disposed on the first lifting mechanism, and the air guide plate assembly is disposed on the rotating mechanism.

[0009] A first sealing structure is provided at the first air outlet, and a second sealing structure is provided on the air guide plate assembly. The first sealing structure and the second sealing structure are sealed together.

[0010] An overlap is formed at the edge of the air guide plate assembly, and a clearance groove is formed at the edge of the first air outlet. When the air guide plate assembly closes the first air outlet, the overlap is located within the clearance groove.

[0011] The first lifting mechanism includes a drive gear and a rack. The drive gear is rotatably mounted on the main frame, and the air guide plate assembly is mounted on the rack via the rotating mechanism. The drive gear and the rack mesh with each other.

[0012] The first lifting mechanism further includes a guide structure, which is disposed on the main frame. The rack is provided with a guide groove, and the guide structure is movably disposed in the guide groove.

[0013] The ceiling hoist also includes a control device, which is electrically connected to the first lifting mechanism and the rotating mechanism. After the first lifting mechanism drives the air guide plate assembly to descend to a set height, the control device controls the rotating mechanism to operate.

[0014] The ceiling machine 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, and the first air outlet is formed on the air outlet assembly.

[0015] 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 assembly opens the first air outlet.

[0016] When the ceiling fan is in the cooling mode, the air guide plate assembly has an angle with the plane where the first air outlet is located.

[0017] 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.

[0018] The air outlet assembly includes an air outlet frame and a return air panel. The air outlet frame forms a second air outlet with 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.

[0019] The ceiling fan provided by this invention, by setting a first lifting mechanism, allows the air guide plate to descend first and then rotate during the opening process, thus eliminating the need to reserve a rotation gap for the air guide plate. When the air guide plate closes the air outlet, the air guide plate and the edge of the air outlet are completely fitted without gaps, which effectively improves the dustproof sealing effect of the ceiling fan and also enhances its aesthetics.

[0028] 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.

[0029] like Figures 1 to 6The illustrated ceiling fan includes: a main frame 1 with a first air outlet 11; and an air guide plate assembly 2, which is movably mounted on the first air outlet 11 via a driving structure. The driving structure includes a first lifting mechanism 3 and a rotating mechanism 4. The first lifting mechanism 3 is mounted on the main frame 1, the rotating mechanism 4 is mounted on the first lifting mechanism 3, and the air guide plate assembly 2 is mounted on the rotating mechanism 4. By using the first lifting mechanism 3, the air guide plate first descends and then rotates during the opening process, thus eliminating the need for a rotation gap. When the air guide plate closes the air outlet, it fits perfectly against the edge of the air outlet without any gaps, effectively improving the dustproof sealing effect of the ceiling fan and also enhancing its aesthetics. Since the air guide plate assembly 2 descends and then rotates when opening the first air outlet 11, the size of the air guide plate assembly 2 can be set to be basically equal to the size of the first air outlet 11. When the ceiling machine stops working (that is, when the air guide plate assembly 2 is at the first air outlet 11), the air guide plate assembly 2 completely closes the first air outlet 11. When the air guide plate assembly 2 opens the first air outlet 11, the air guide plate assembly 2 descends a certain distance first, so that the air guide plate assembly 2 is at least partially separated from the first air outlet 11. At this time, when the air guide plate assembly 2 is rotated, the air guide plate assembly 2 will not interfere with the edge of the first air outlet 11, thus ensuring that the rotation of the air guide plate assembly 2 is reliable. When the air guide plate assembly 2 closes the first air outlet 11, the air guide plate assembly 2 is first rotated to a set angle, and then the air guide plate assembly 2 is raised, so that the air guide plate assembly 2 closes the first air outlet 11. During the rising process, the air guide plate assembly 2 does not need to rotate, so the side of the air guide plate assembly 2 can maintain a small gap with the edge of the first air outlet 11. After the air guide plate assembly 2 closes the first air outlet 11, there is no obvious gap on the surface of the ceiling machine, which effectively improves the aesthetics of the ceiling machine.

[0030] The rotating mechanism 4 can be a stepper motor, etc. The air guide plate assembly 2 is either connected to the rotating shaft of the stepper motor via a transmission or directly.

[0031] The air guide plate assembly 2 includes an air guide plate and related structures that cooperate with the air guide plate, wherein the air guide plate serves to guide air and close the first air outlet 11.

[0032] Since there is no need to reserve a rotation gap for the air guide plate assembly 2, the sealing effect between the air guide plate assembly 2 and the first air outlet 11 can be further improved. Therefore, a first sealing structure is provided at the first air outlet 11, and a second sealing structure is provided on the air guide plate assembly 2. The first sealing structure and the second sealing structure are sealed together. When the air guide plate assembly 2 is sealed at the first air outlet 11, the first sealing structure and the second sealing structure fit together tightly, thereby effectively improving the sealing effect.

[0033] In one embodiment, an overlap 21 is formed at the edge of the air guide plate assembly 2, and a clearance groove 12 is formed at the edge of the first air outlet 11. When the air guide plate assembly 2 closes the first air outlet 11, the overlap 21 is located within the clearance groove 12. The cooperation of the overlap 21 and the clearance groove 12 effectively improves the sealing effect of the air guide plate assembly 2 and the first air outlet 11. Simultaneously, the overlap 21 can shield the first air outlet 11, preventing gaps between the air guide plate assembly 2 and the first air outlet 11 from potentially exposing the internal structure of the ceiling fan, further enhancing the aesthetics of the ceiling fan.

[0034] The first lifting mechanism 3 includes a drive gear 31 and a rack 32. The drive gear 31 is rotatably mounted on the main frame 1. The air guide plate assembly 2 is mounted on the rack 32 via the rotating mechanism 4, and the drive gear 31 and the rack 32 mesh with each other. The drive gear 31 rotates under the drive of a motor or other power component, which in turn moves the rack 32 vertically, thus ensuring that the air guide plate assembly 2 moves vertically to achieve lifting and lowering. The power component can be a stepper motor or similar device.

[0035] To ensure that the rack 32 and the air guide plate assembly 2 can move up and down in a set direction, the first lifting mechanism 3 further includes a guide structure 33. The guide structure 33 is disposed on the main frame 1, and the rack 32 is provided with a guide groove. The guide structure 33 is movably disposed within the guide groove. The guide structure 33 limits the guide groove, restricts the movement direction of the rack 32, and ensures reliable movement of the air guide plate assembly 2.

[0036] The guide structure 33 can be a guide wheel, which can roll with the guide groove during the lifting and lowering of the rack 32.

[0037] The first lifting mechanism 3 can also be a crank-slider structure, a spring cam structure, a gear cam-connecting rod structure, etc., all of which can achieve reliable lifting of the air guide plate assembly 2.

[0038] To ensure reliable movement of the air guide plate assembly 2, the ceiling fan also includes a control device. This control device is electrically connected to the first lifting mechanism 3 and the rotating mechanism 4. After the first lifting mechanism 3 lowers the air guide plate assembly 2 to a set height, the control device controls the rotating mechanism 4 to operate. That is, by controlling the first lifting mechanism 3 and the rotating mechanism 4, only when the first lifting mechanism 3 lowers the air guide plate assembly 2 to a set height will the rotation of the air guide plate assembly 2 not interfere with the first air outlet 11. Therefore, the rotating mechanism 4 can be controlled to rotate the air guide plate assembly 2, achieving full opening of the first air outlet 11.

[0039] Preferably, the height is set to be no less than the thickness of the air guide plate assembly 2. This dimension can ensure that the air guide plate assembly 2 can rotate reliably even when there is an overlap 21.

[0040] To enable the joist unit to blow air horizontally in cooling mode, allowing the airflow to adhere to the wall, the joist unit also includes an air outlet assembly 5. This assembly 5 is vertically and flexibly mounted on the main frame 1, and its descent forms a second air outlet 13 with the main frame 1. The first air outlet 11 is formed on the air outlet assembly 5. The main frame 1 is fixedly positioned on the outer circumference of the air outlet assembly 5. When the joist unit is operating, the air outlet assembly 5 descends to a certain height, creating a height difference with the main frame 1. The air outlet assembly 5 and the main frame 1, positioned outside the air outlet assembly 5, form the second air outlet 13. The fan blows air from inside the joist unit 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.

[0041] The ceiling fan has a cooling mode. When the ceiling fan is in cooling mode, the air outlet assembly 5 descends to open the second air outlet 13, and the air guide plate assembly 2 opens the first air outlet 11. Figure 5 or Figure 6 As shown, 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 blown out diagonally downwards to increase the cooling effect on the room.

[0042] To further increase the air volume at the first air outlet 11, such as Figure 6 As shown, when the ceiling fan is in the cooling mode, the air guide plate assembly 2 forms an angle with the plane where the first air outlet 11 is located. By rotating the air guide plate assembly 2, the airflow from the first air outlet 11 is increased, thereby improving the cooling effect.

[0043] Or, such as Figure 4 As shown, when the ceiling fan is in cooling mode, only the air guide plate assembly 2 opens the first air outlet 11. The cold air from the ceiling fan 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.

[0044] The ceiling fan also has a heating mode. When the ceiling fan is in heating mode, the air outlet assembly 5 can descend to open the second air outlet 13, and at the same time, the air guide plate assembly 2 opens the first air outlet 11. Figure 5 or Figure 6 As shown, at this time, the ballast heater can heat with the maximum air output, improving the heating efficiency of the ballast heater.

[0045] Alternatively, when the ceiling fan is in heating mode, only the air guide plate assembly 2 opens the first air outlet 11, such as... Figure 4 As shown, at this time, the air from the ceiling fan is blown downwards quickly through the first air outlet 11, thereby achieving the purpose of rapid heating.

[0046] The air outlet assembly 5 includes an air outlet frame, and a second air outlet 13 is 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 5 includes an air outlet frame and a return air panel, and a second air outlet 13 is 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.

[0047] 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.
