Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a ceiling-mounted air conditioner. Background Technology

[0002] Ceiling-mounted air conditioners, also known as ceiling-mounted or recessed air conditioners, are installed with only the air outlet visible, concealing the indoor unit. They are aesthetically pleasing and offer excellent temperature control, making them a popular choice for large apartments and villas. However, existing ceiling-mounted air conditioners are limited by the size of the air outlet and a single airflow method, typically resulting in only a noticeable breeze in the area directly opposite the outlet, while other horizontal areas experience little to no breeze. This can lead to uneven temperature distribution and poor heating performance. Therefore, ceiling-mounted air conditioners with a swing function have been developed to address these issues.

[0003] Typically, the air-sweeping structure can obstruct the electrical control box and other structures on the ceiling unit, requiring the entire air-sweeping structure to be disassembled before the electrical control box can be opened for troubleshooting, which makes maintenance difficult. In addition, the wiring structure of the electrical control module of the air-sweeping structure is relatively complex and difficult to assemble.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The problem solved by this invention is that the existing ceiling air conditioner with air-sweeping function has an unreasonable structure, which leads to high difficulty and low efficiency in the operation of the electrical control box during maintenance.

[0006] The present invention provides a ceiling-mounted air conditioner, including a main body, the main body including a water receiving tray, a sweeping frame and an electrical control box disposed below the water receiving tray, the sweeping frame including an electrical control structure, the electrical control structure being located directly below the electrical control box and there is a gap between the two.

[0007] This design ensures that the electrical control structure does not interfere with the opening of the electrical control box. After opening the decorative panel, the electrical control box is fully exposed, facilitating maintenance of the ceiling-mounted unit. Simultaneously, the gap allows the airflow to carry away the heat generated by the electrical control structure and box, ensuring stable and reliable heat dissipation. The swing frame allows for the oscillating airflow of the ceiling-mounted unit, further expanding the airflow coverage and facilitating rapid indoor temperature adjustment for a better user experience. As an example of this invention, the gap between the electrical control structure and the electrical control box is 0.5-1.5 cm.

[0008] Preferably, the air-sweeping frame includes a U-shaped frame with an air passage hole in the middle, and the electronic control structure is located on the frame near the air passage hole, with a gap between the electronic control structure and the frame.

[0009] This design prevents heat generated by the electronic control structure from being conducted to the frame. At the same time, the airflow can cover both sides of the electronic control structure when passing through the air vents, resulting in good heat dissipation performance and stable and reliable overall operation.

[0010] Preferably, the electronic control structure includes a detachably connected housing and a cover, the cover being located on the side of the housing away from the frame, and a gap H of 0.8-1.5 cm between the housing and the frame. This arrangement prevents the electronic control structure from interfering with the air intake of the vents, while ensuring good heat dissipation of the electronic control structure.

[0011] Preferably, the frame is fixedly provided with sheet metal parts, on which a first support plate and a second support plate are provided. The first support plate is fixedly connected to the box body, and the second support plate is fixedly connected to the box cover. This arrangement has a simple structure, stable and reliable connection, and is convenient for production and processing.

[0012] Preferably, an air outlet is provided on the outer periphery of the air passage, and the end portion of the air outlet is recessed to form a first groove. The sidewall of the first groove expands outward from bottom to top along the length direction of the air outlet to form a first guide slope.

[0013] This design guides the airflow towards the center of the air outlet, effectively preventing the airflow from colliding with the periphery of the first groove and causing condensation. In addition, it ensures that all the airflow is discharged through the air outlet, preventing some of the airflow from entering the gap between the sweeping frame and the main body due to changes in air pressure during the sweeping process, thereby preventing turbulent airflow and resulting in low overall operating noise.

[0014] Preferably, the first groove slopes upwards from the bottom to the side of the air passage away from the air passage, forming a second guide slope. This arrangement helps guide the airflow from both ends of the air outlet towards the middle position, ensuring smooth airflow and low noise.

[0015] Preferably, a first protrusion is provided on the side wall of the air outlet along its length direction. The first protrusion is located in the middle of the air outlet and away from the air passage hole. A first groove is provided at both ends of the air outlet. The first grooves are symmetrically provided on the left and right sides of the first protrusion. A second groove is formed between the first protrusion and the first groove.

[0016] This design guides the airflow at the end of the air outlet, making the airflow smoother; at the same time, the narrower width of the air outlet at the first groove appropriately increases the airflow velocity in the corresponding area, which helps to achieve a uniform distribution of the overall airflow velocity at the air outlet.

[0017] Preferably, a sweeping assembly is provided inside the air outlet. The sweeping assembly includes an assembly plate, a drive device, and blades. One side of the assembly plate is attached to the side wall of the air outlet. The blades and the drive device are located on opposite sides of the assembly plate. The output end of the drive device is connected to one end of a crank, and the other end of the crank is connected to the blades via a connecting rod. This arrangement ensures that all blades are driven and connected via connecting rods, resulting in stable and reliable transmission during left and right air guidance and a long service life.

[0018] Preferably, a notch is provided on the frame, the notch connects the air passage hole and the air outlet for accommodating the drive device, and a wiring groove is provided on the upper side of the frame, the wiring groove is provided along the periphery of the air passage hole and communicates with the notch.

[0019] This design makes full use of the frame space, resulting in a simple structure and convenient wiring. A connecting rod is located below the assembly plate, perpendicular to the assembly plate. The first boss has a mating groove, and one end of the connecting rod is fitted into the mating groove. This design allows the air-sweeping assembly to be fixed on both sides of the air outlet, providing good assembly strength.

[0020] Preferably, the air-sweeping frame further includes a first sheet metal part, which is fixedly mounted on the frame and covers the wiring channel. This arrangement strengthens the overall structure of the frame and conceals the wiring channel to prevent exposed connecting wires, resulting in a more aesthetically pleasing appearance.

[0021] Compared with the prior art, the ceiling air conditioner described in this embodiment of the invention has the following beneficial effects: 1) The ceiling air conditioner can swing to expand the air outlet coverage, which is conducive to rapid indoor temperature adjustment; at the same time, the swing frame will not interfere with the opening of the electrical control box, which is convenient for the maintenance of the ceiling air conditioner; 2) It effectively prevents the heat generated by the electrical control structure from being conducted to the frame, and at the same time, the air inlet can cover both sides of the electrical control structure to carry away the heat when passing through the air hole, resulting in good heat dissipation performance; 3) It can guide the air outlet to the central area of ​​the air outlet, avoiding condensation caused by the air outlet colliding with the frame.

Detailed Implementation

[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the technical features of the various embodiments of the present invention can be combined with each other.

[0039] In the embodiments of this invention, the directional terms used are based on the normal assembly and installation of the ceiling-mounted indoor unit. "Upper" refers to the upper direction or space of the ceiling-mounted indoor unit under normal assembly and installation conditions; "lower" refers to the lower direction or space of the ceiling-mounted indoor unit under normal assembly and installation conditions; and "horizontal" refers to the horizontal plane direction of the ceiling-mounted indoor unit under normal assembly and installation conditions, consistent with conventional understanding. Furthermore, the descriptions involving "first," "second," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] like Figure 1-3 As shown, a ceiling air conditioner includes a main body 1, which includes a water receiving tray 11. A sweeping frame 2 and an electrical control box 13 are disposed below the water receiving tray 11. The sweeping frame 2 includes an electrical control structure 24, which is located below the electrical control box 13 and there is a gap between the two.

[0042] This design ensures that the electrical control structure 24 does not interfere with the opening of the electrical control box 13. After opening the decorative panel 3, the electrical control box 13 will be fully exposed, facilitating the maintenance of the ceiling unit. By setting the air swing frame 2, the swing air outlet of the ceiling unit can be further expanded to expand the air outlet coverage, which is conducive to achieving rapid indoor temperature adjustment and providing a better user experience.

[0043] The ceiling-mounted unit also includes a decorative panel 3, which is located below the air-sweeping frame 2. The air-sweeping frame 2 is detachably connected to the main body 1 and the decorative panel 3. The specific structure of the assembly panel 3 is prior art and will not be described in detail here.

[0044] Preferably, the main body 1 further includes a housing 14, in which a wind turbine assembly 12 is disposed. The lower part of the housing 14 is detachably connected to the water receiving tray 11. An electrical control box 13 is disposed on the water receiving tray 11 and is electrically connected to the wind turbine assembly 12.

[0045] like Figure 3-4 As shown, the sweeping frame 2 includes a "U"-shaped frame 26 with an air passage hole 27 in the middle. An air outlet 21 is provided on the outer periphery of the air passage hole 27, and a sweeping assembly 22 is arranged at the air outlet 21 to guide the airflow. The electrical control structure 24 is located on the frame 26 near the air passage hole 27 and is electrically connected to the sweeping assembly 22. This arrangement allows the electrical control structure 24 to be located close to the electrical control box 13, resulting in a simple structure and convenient wiring.

[0046] As an example of the present invention, the electronic control structure 24 includes a detachably connected housing 242 and a cover 243. The cover 243 is located on the side of the housing 242 away from the frame 26, and there is a gap H between the housing 242 and the frame 26, where H = 0.8-1.5 cm. This arrangement can prevent the heat generated by the electronic control structure 24 from being conducted to the frame 26. At the same time, the airflow passing through the air vents 27 can cover both sides of the electronic control structure 24, resulting in good heat dissipation performance and stable and reliable overall operation.

[0047] Preferably, the electrical control structure 24 further includes a sheet metal part 241 fixedly mounted on the frame 26. A first support plate 2411 is provided on the sheet metal part 241, and the first support plate 2411 is fixedly connected to the box body 242. A second support plate 2412 is also provided on the sheet metal part 241, and the second support plate 2412 is fixedly connected to the box cover 243. This arrangement is simple in structure, provides a stable and reliable connection, and facilitates production and processing.

[0048] As a preferred embodiment of the present invention, a wiring groove 265 is provided on the frame 26, and the air-sweeping frame 2 further includes a first reinforcing member 23, which is fixedly assembled on the frame 26 to cover the wiring groove 265. This arrangement can strengthen the overall structure of the frame 26, and at the same time cover the wiring groove 265 to prevent the connecting wires from being exposed, making the overall appearance more aesthetically pleasing.

[0049] Preferably, a second reinforcing member 25 is provided on the frame 26, and the second reinforcing member 25 is disposed adjacent to the electrical control structure 24. This arrangement can further strengthen the frame 26, has a simple structure, and is easy to manufacture.

[0050] like Figure 5-7 As shown, a first protrusion 211 is provided on the side wall of the air outlet 21 along its length. The first protrusion 211 is located in the middle of the air outlet 21 and is far away from the air passage 27. A first groove 212 is provided at both ends of the air outlet 21. The first groove 212 is symmetrically provided on the left and right sides of the first protrusion 211. A second groove 213 is formed between the first protrusion 211 and the first groove 212. The side wall of the first groove 212 gradually expands from bottom to top away from the first protrusion 211 to form a first guide slope 2121.

[0051] This setting can guide the airflow towards the center of the air outlet 21, thereby effectively preventing the airflow from colliding with the periphery of the first groove 212 and causing condensation; in addition, it can ensure that all the airflow is discharged through the air outlet 21, preventing some of the airflow from entering the gap between the sweeping frame 2 and the main body 1 due to changes in air pressure during the sweeping process, thereby preventing the airflow from becoming turbulent and resulting in low overall operating noise.

[0052] Preferably, the sidewall of the first groove 212, on the side away from the air passage 27, slopes upwards towards the second groove 213 to form a second guide slope 2122. This arrangement guides the airflow at the end of the air outlet 21, making the airflow smoother; at the same time, the narrower width of the air outlet 21 at the first groove 212 appropriately increases the airflow velocity in the corresponding area, thereby helping to achieve a uniform overall velocity distribution at the air outlet 21.

[0053] The air outlet 21 has three corresponding air outlet areas: a1 (first area), a2 (second area), and a3 (third area) at the first groove 212, second groove 213, and first protrusion 211, respectively. The lengths of the first area a1, second area a2, and third area a3 are L3, L1, and L2, respectively, and the widths of the first area a1, second area a2, and third area a3 are L6, L4, and L5, respectively, where L3:L1:L2 = (1-2):(4-6):(8:12) and L6:L4:L5 = (7-9):(12-14):(10-12). This arrangement causes the widths of adjacent first area a1, third area a3, and second area a2 to gradually increase. In other words, the width of the air outlet 21 first increases and then decreases from the middle position towards both ends, thereby making the overall airflow velocity of the air outlet 21 more uniform. At the same time, it ensures that the wind speed in the middle area of ​​the air outlet 21 is relatively faster, thus increasing the air delivery distance. It should be noted that the size of the air outlet 21 refers to the actual size of the air outlet 21 formed after the air sweeping assembly 22 is installed onto the frame 26. Preferably, the values ​​of L1-L6 are 10cm, 18cm, 3cm, 6.5cm, 5.5cm, and 4.0cm, respectively. Experiments have shown that the air outlet 21 exhibits the best airflow smoothness and anti-condensation effect under the above parameters.

[0054] The maximum length of the air outlet 21 near the main body 1 is L7, and the height of the air outlet 21 is H, where L7:(L2+2*L1+2*L3)=(1.05-1.1):1, L7:H=5.5-7:1. This setting effectively prevents airflow turbulence and improves air delivery. The distance between the first guide slope 2121 and the upper surface of the frame 26 is M1, where M1=(0.4-0.6)H. This setting maximizes the airflow into the air outlet 21, and the first guide slope 2121 and the second guide slope 2122 converge the airflow towards the middle area of ​​the air outlet 21, resulting in smoother airflow. Preferably, the values ​​of L7, H, and M1 are 50cm, 8cm, and 4.0cm, respectively, at which point the overall performance of the sweeping frame 2 is optimal.

[0055] like Figure 8-14As shown, the air-sweeping assembly 22 includes an assembly plate 221, a drive device 222, and blades 224. One side of the assembly plate 221 is attached to the side wall of the air outlet 21. The blades 224 and the drive device 222 are located on opposite sides of the assembly plate 221. The output end of the drive device 222 is connected to one end of a crank 226, and the other end of the crank 226 is connected to the blades 224 via a connecting rod 225. This configuration ensures stable and reliable transmission of the air-sweeping assembly 22 and extends its service life.

[0056] Preferably, the air outlet 21 has a limiting groove 262 on the side wall near the air passage 27, and the end of the assembly plate 221 has an insert 2217 that can be embedded in the limiting groove 262. This arrangement can constrain the assembly position of the air sweeping assembly 22, resulting in high assembly accuracy; at the same time, it makes the side wall surface of the air outlet 21 near the air passage 27 flat, so as not to interfere with the airflow.

[0057] As a preferred embodiment of the present invention, the frame 26 is provided with a support rod 261, which is located above the air outlet 21 and close to the limiting groove 262. This arrangement can strengthen the air outlet 21 and prevent deformation under the action of the airflow.

[0058] Preferably, a notch 263 is provided on the frame 26, which connects the air passage 27 to the air outlet 21 for accommodating the drive device 222. A wiring groove 265 is provided on the upper side of the frame 26, which runs along the periphery of the air passage 27 and connects to the notch 263. This arrangement makes full use of the space of the frame 26, resulting in a simple structure and convenient wiring. A connecting rod 223 is provided below the assembly plate 221, perpendicular to the assembly plate 221. The first boss 211 has a mating groove 264, and one end of the connecting rod 223 is fitted into the mating groove 264. This arrangement allows the air sweeping assembly 22 to be fixed on both sides of the air outlet 21, resulting in good assembly strength.

[0059] As a preferred embodiment of the present invention, a first mounting groove 2211 is provided on one side of the mounting plate 221. The first mounting groove 2211 is inclined and is used to accommodate the third blade 2243. Two first protrusions 2216 are provided on the first mounting groove 2211, located on opposite sides of the first mounting groove 2211, for limiting the position of the third blade 2243. The first mounting groove 2211 can limit the position of the third blade 2243 on the plane of the mounting plate 221, while the first protrusions 2216 can limit the position of the third blade 2243 in a direction perpendicular to the mounting plate 221.

[0060] Preferably, the assembly plate 221 is provided with a second assembly groove 2212 and a first limiting member 2215. The first limiting member 2215 is located on the side of the second assembly groove 2212 near the air outlet 21. The projection of the first limiting member 2215 on the assembly plate 221 coincides with the second assembly groove 2212, and is used to limit the assembly of the first blade 2241 or the second blade 2242.

[0061] Preferably, the second assembly groove 2212 is formed by a downward recess of the assembly plate 221. The projection of the first limiting member 2215 onto the plane of the assembly plate 221 is rectangular, and a notch is provided at a corresponding position on the first blade 2241. When the notch is aligned with the first limiting member 2215, the first blade 2241 is installed into the second assembly groove 2212. After the first blade 2241 rotates, it can be abutted and limited by the first limiting member 2215 to prevent it from falling out of the second assembly groove 2212.

[0062] Preferably, the assembly plate 221 is provided with a third assembly slot 2213, which is located between the first assembly slot 2211 and the second assembly slot 2212, and is used to limit the assembly of the output end of the drive device 222. The assembly plate 221 is provided with two fourth assembly slots 2214, which are located above the third assembly slot 2213, and are used to assemble the drive device 222.

[0063] As a preferred example of the present invention, the drive device 222 includes a first mounting plate 2221 and a second mounting plate 2222 that are detachably connected. The first mounting plate 2221 is fixedly mounted on the mounting plate 221. A transmission structure 2223 is disposed within the first mounting plate 2221. A motor 2224 is disposed on the side of the second mounting plate 2222 away from the first mounting plate 2221. The motor 2224 is drivenly connected to the transmission structure 2223. The output end of the transmission structure 2223 is connected to the crank 226. This configuration is compact, provides stable and reliable transmission, and facilitates wiring and installation.

[0064] Preferably, a second limiting member 2226 is provided on the side of the first mounting plate 2221, and a second protrusion 2227 is provided on the second mounting plate 2222 at a position corresponding to the second limiting member 2226. The second limiting member 2226 and the second protrusion 2227 are engaged and connected. This arrangement enables pre-assembly between the first mounting plate 2221 and the second mounting plate 2222, resulting in high assembly efficiency.

[0065] Preferably, a fixing post 2228 is provided on the first mounting plate 2221 at a position corresponding to the fourth assembly slot 2214, and the free end of the fixing post 2228 abuts against the second mounting plate 2222. This arrangement not only achieves the fixation between the assembly plate 221 and the second mounting plate 2222, but also limits the assembly between the first mounting plate 2221 and the second mounting plate 2222, resulting in high assembly accuracy and good reliability.

[0066] As an example of the present invention, the transmission structure 2223 includes a first gear 22231, a second gear 22232, and a third gear 22233 that are sequentially meshed. The second gear 22232 is a double gear, and the third gear 22233 is driven by the motor 2224. An arc-shaped stop 2225 is provided on the first mounting plate 2221. The first gear 22231 is a sector gear and is located on the circle of the stop 2225. The arc of the stop 2225 is (1 / 3-1 / 2)π, and the arc of the first gear 22231 is (3 / 4-5 / 6)π. This arrangement can limit the rotation position of the first gear 22231 by the stop 2225, thereby constraining the rotation angle of the blade 224 and ensuring stable and reliable transmission.

[0067] As a preferred example of the present invention, the blade 224 includes a first blade 2241 and a second blade 2242 rotatably disposed on the mounting plate 221. The second blade 2242 is located on both sides of the first blade 2241, and the length of the first blade 2241 is less than that of the second blade 2242. This arrangement can be adapted to the specific structure of the air outlet 21, and the left and right air guiding effect is good.

[0068] Preferably, the blade 224 further includes an inclined third blade 2243, which is located on the side of the second blade 2242 away from the first blade 2241, and the inclination direction of the third blade 2243 is the same as the inclination direction of the adjacent first guide slope 2121.

[0069] By setting the third blade 2243, the airflow direction at the end of the air outlet 21 is guided to the center position, thereby cooperating with the first guide slope 2121 to avoid condensation caused by the blade 224 rotating and changing the airflow direction and colliding with the surrounding area along the length direction of the air outlet 21. At the same time, the third blade 2243 cooperates with the first guide slope 2121 to achieve a gradual effect, gradually changing the airflow direction and reducing operating resistance.

[0070] As an example of the present invention, the third blade 2243 includes a mounting rod 22431, on which a guide plate 22432 and a limiting seat 22243 are disposed. A reinforcing plate 22434 is disposed between the limiting seat 22243 and the guide plate 22432. The limiting seat 22243 is fitted into the first mounting groove 2211, and the end of the limiting seat 22243 near the reinforcing plate 22434 abuts against the first protrusion 2216. This arrangement allows the third blade 2243 to be quickly assembled onto the mounting plate 221 via a snap-fit ​​connection, facilitating assembly and disassembly.

[0071] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
