Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a ceiling air conditioner. Background Art

[0002] Ceiling air conditioners, also known as patio air conditioners or ceiling-mounted or embedded air conditioners, only have the air outlet exposed after installation, and the internal unit cannot be seen. They have a beautiful appearance and good temperature control effect, and have gradually become the first choice for large apartments and villas. As the existing ceiling air conditioners are limited by the size of the air outlet and the single air outlet and air guide method, usually only the area directly facing the air outlet has a clear sense of wind, while other areas in the horizontal direction have little sense of wind. During use, it is easy to have uneven spatial temperature distribution and poor thermal effect. For this reason, ceiling air conditioners with wind sweeping function came into being.

[0003] Usually, the wind sweeping structure will block the electronic control box and other structures on the ceiling machine, which means that the wind sweeping structure needs to be completely dismantled during maintenance before the electronic control box can be opened for troubleshooting, which makes maintenance difficult. In addition, the wiring structure of the electronic control module of the wind sweeping structure is relatively complex and difficult to assemble.

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

[0005] The problem solved by the invention is that the structure of the existing ceiling fan with wind sweeping function is unreasonable, which leads to great difficulty and low efficiency in the maintenance of the electric control box.

[0006] The present invention provides a ceiling machine, comprising a main body, wherein the main body comprises a water receiving tray, a wind sweeping frame and an electric control box are arranged below the water receiving tray, the wind sweeping frame comprises an electric control structure, and the electric control structure is located directly below the electric control box with a gap therebetween.

[0007] This setting prevents the electric control structure from interfering with the opening of the electric control box. After opening the decorative panel, the electric control box will be completely exposed, which is convenient for the maintenance of the ceiling machine. At the same time, the gap can allow the airflow to take away the heat generated by the electric control structure and the electric control box, and the heat dissipation is stable and reliable. By setting the wind sweeping frame, the ceiling machine can be swung to discharge air to further expand the air outlet coverage, which is conducive to rapid indoor temperature adjustment and better user experience. As an example of the present invention, the gap between the electric control structure and the electric control box is 0.5-1.5cm.

[0013] This setting can guide the outlet air flow to the center position of the air outlet, thereby effectively avoiding the outlet air flow from colliding with the periphery of the first groove and generating condensation; in addition, it can make all the outlet air flow be discharged through the air outlet, preventing part of the outlet air flow from entering the gap between the air sweeping frame and the main body due to changes in wind pressure during the air sweeping process, thereby preventing the inlet air flow from being turbulent, and the overall operating noise is low.

[0014] Preferably, the side wall of the first groove on the side away from the air hole is inclined from bottom to top toward the side away from the air hole and forms a second guiding slope. This arrangement is conducive to guiding the airflow at both ends of the air outlet to the middle position, ensuring smooth airflow and low noise.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be noted that the technical features of each embodiment of the present invention can be combined with each other.

[0039] The directional terms mentioned in the embodiments of the present invention are all based on the normal assembly and normal installation of the indoor unit of the ceiling machine, where "upper" refers to the upper direction or space of the normal assembly and normal installation of the indoor unit of the ceiling machine, "lower" refers to the lower direction or space of the normal assembly and normal installation of the indoor unit of the ceiling machine, and "horizontal" refers to the horizontal plane direction of the normal assembly and normal installation of the indoor unit of the ceiling machine, which is the same as the conventional understanding. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1-3 As shown, a ceiling machine includes a main body 1, wherein the main body 1 includes a water receiving tray 11, and a wind sweeping frame 2 and an electric control box 13 are arranged below the water receiving tray 11. The wind sweeping frame 2 includes an electric control structure 24, and the electric control structure 24 is located below the electric control box 13 and there is a gap between the two.

[0042] This arrangement ensures that the electric control structure 24 will not interfere with the opening of the electric control box 13. After opening the decorative panel 3, the electric control box 13 will be completely exposed, which is convenient for the maintenance of the ceiling machine. By setting up the wind sweeping frame 2, the ceiling machine can be swung to discharge air to further expand the air outlet coverage, which is conducive to achieving rapid temperature control in the room and providing a better user experience.

[0043] The ceiling machine further comprises a decorative panel 3, which is located below the wind sweeping frame 2, and the wind 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 also includes a shell 14, a wind wheel assembly 12 is arranged in the shell 14, the lower part of the shell 14 is detachably connected to the water receiving tray 11, an electric control box 13 is arranged on the water receiving tray 11, and the electric control box 13 is electrically connected to the wind wheel assembly 12.

[0045] like Figure 3-4 As shown, the wind sweeping frame 2 includes a "mouth-shaped" frame 26, a wind hole 27 is formed in the middle of the frame 26, an air outlet 21 is arranged on the outer peripheral side of the air hole 27, and a wind sweeping component 22 is arranged at the position of the air outlet 21 for guiding the outlet air flow; the electric control structure 24 is arranged at a position of the frame 26 close to the wind hole 27, and the electric control structure 24 is electrically connected to the wind sweeping component 22. This arrangement enables the electric control structure 24 to be arranged close to the electric control box 13, which has a simple structure and is convenient for wiring.

[0046] As an example of the present invention, the electric control structure 24 includes a detachably connected box body 242 and a box cover 243, the box cover 243 is located on the side of the box body 242 away from the frame body 26, and there is a gap H between the box body 242 and the frame body 26, where H = 0.8-1.5 cm. This setting can prevent the heat generated by the electric control structure 24 from being transferred to the frame body 26, and at the same time, the air intake airflow can cover both sides of the electric control structure 24 when passing through the air hole 27, so that the heat dissipation performance is good, and the overall operation is stable and reliable.

[0047] Preferably, the electric control structure 24 further comprises a sheet metal part 241 fixedly mounted on the frame 26, a first support plate 2411 is arranged 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 arranged on the sheet metal part 241, and the second support plate 2412 is fixedly connected to the box cover 243. This arrangement has a simple structure, a stable and reliable connection, and is convenient for production and processing.

[0048] As a preferred example of the present invention, a wiring groove 265 is provided on the frame 26, and the wind sweeping frame 2 further includes a first reinforcement member 23, which is fixedly mounted on the frame 26 and used to shield the wiring groove 265. This arrangement can strengthen the overall structure of the frame 26, and at the same time shield the wiring groove 265 to prevent the connection line from leaking out, making the overall appearance more beautiful.

[0049] Preferably, a second reinforcing member 25 is provided on the frame 26, and the second reinforcing member 25 is provided adjacent to the electric control structure 24. This arrangement can further strengthen the frame 26, has a simple structure, and is convenient for production and processing.

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

[0051] This setting can guide the outlet air flow to the center position of the air outlet 21, thereby effectively avoiding the outlet air flow from colliding with the periphery of the first groove 212 and generating condensation; in addition, it can make all the outlet air flow be discharged through the air outlet 21, preventing part of the outlet air flow from entering the gap between the air sweeping frame 2 and the main body 1 due to changes in wind pressure during the air sweeping process, thereby preventing the inlet air flow from being turbulent, and the overall operating noise is low.

[0052] Preferably, the side wall of the first groove 212 away from the air hole 27 is inclined from bottom to top toward the second groove 213 to form a second guiding slope 2122. This arrangement can guide the airflow at the end of the air outlet 21 to make the air outlet smoother; at the same time, the width of the air outlet 21 at the first groove 212 is narrower, so that the airflow velocity of the corresponding area is appropriately increased, which is conducive to achieving uniform distribution of the overall flow velocity at the air outlet 21.

[0053] The outlet areas of the air outlet 21 corresponding to the first groove 212, the second groove 213, and the first boss 211 are the first area a1, the second area a2, and the third area a3, respectively. The lengths of the first area a1, the second area a2, and the third area a3 are L3, L1, and L2, respectively. The widths of the first area a1, the second area a2, and the third area a3 are L6, L4, and L5, respectively, wherein L3:L1:L2=(1-2):(4-6):(8:12), L6:L4:L5=(7-9):(12-14):(10-12). This setting makes the widths of the adjacent first area a1, the third area a3, and the second area a2 gradually increase, that is, the width of the air outlet 21 from the middle position to the two ends first increases and then decreases, so that the air flow velocity of the air outlet 21 is relatively uniform as a whole, and at the same time ensures that the wind speed in the middle area of ​​the air outlet 21 is relatively faster, thereby increasing the air supply distance of the air flow. 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 on the frame 26. Preferably, the values ​​of L1-L6 are 10 cm, 18 cm, 3 cm, 6.5 cm, 5.5 cm, and 4.0 cm, respectively. It has been found through experiments that the air outlet 21 has the best air outlet smoothness and anti-condensation effect under the above parameters.

[0054] The maximum length of the air outlet 21 on the side close to 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 can effectively prevent the outlet air flow from being turbulent, and the air supply effect is better. The distance between the first guide slope 2121 and the upper end surface of the frame 26 is M1, where M1=(0.4-0.6)H. This setting can make the outlet air flow enter the air outlet 21 as much as possible, and through the first guide slope 2121 and the second guide slope 2122, the outlet air flow is gathered to the middle area of ​​the air outlet 21, and the air outlet is smoother. Preferably, the values ​​of L7, H, and M1 are 50cm, 8cm, and 4.0cm, respectively, at which time the overall performance of the wind sweeping frame 2 is optimal.

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

When the notch is aligned with the first limiting member 2215, the first blade 2241 is installed in the second assembly groove 2212, and the first blade 2241 can be abutted and limited by the first limiting member 2215 after rotating, so as to prevent it from falling out of the second assembly groove 2212.

[0062] Preferably, the assembly plate 221 is provided with a third assembly groove 2213, and the third assembly groove 2213 is located between the first assembly groove 2211 and the second assembly groove 2212, and is used to limit and assemble the output end of the driving device 222.

[0065] Preferably, a fixing column 2228 is provided on the first mounting plate 2221 at a position corresponding to the position of the fourth mounting groove 2214, and the free end of the fixing column 2228 abuts against the second mounting plate 2222. This arrangement can not only realize the fixation between the assembly plate 221 and the second mounting plate 2222, but also limit the assembly between the first mounting plate 2221 and the second mounting plate 2222, with high assembly precision 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 meshed and connected in sequence, the second gear 22232 is a double gear, the third gear 22233 is connected to the motor 2224, an arc-shaped stopper 2225 is arranged on the first mounting plate 2221, the first gear 22231 is a fan-shaped gear, the first gear 22231 is arranged on the circle where the stopper 2225 is located, the arc corresponding to the stopper 2225 is (1 / 3-1 / 2)π, and the arc corresponding to the first gear 22231 is (3 / 4-5 / 6)π.
