Description

Technical Field

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

[0002] Ceiling air conditioners (also known as suspended ceiling air conditioners) are popular among users due to their small footprint and flexible installation methods. They are widely used in offices, shopping malls, hotels and other places. The kitchen is a common application scenario for ceiling air conditioners. Since there are a lot of oil smoke and water vapor in the kitchen, pollutants easily adhere to the surface of the fan blades and coils during long-term circulation. In order to increase the service life of the kitchen air conditioner, the fan needs to be cleaned or replaced. The existing internal motor fixing methods are relatively complicated, such as setting up a separate motor fixing bracket or a fixing bracket that is integrally formed with the motor. One end of the fixing bracket is fixed to the side of the motor, and the other end is fixed to the top of the unit by fixing screws and nuts. This structure affects the upper space inside the air conditioner. Space must be reserved for fixing the motor and the fixing bracket, so the effective use of space is relatively reduced. Due to the installation position and method, the upper space of the ceiling air conditioner is limited to a certain extent, and the motor installed in this way is not convenient for transportation, disassembly and maintenance. Summary of the Invention

[0003] Therefore, the present invention provides a ceiling-mounted air conditioner, which can solve the technical problem in the prior art that the fixing method of the motor in the ceiling-mounted air conditioner occupies a large height space.

[0004] In order to solve the above problems, the present invention provides a ceiling-mounted air conditioner, including an outer shell for ceiling assembly, a heat exchanger bracket is connected to the outer shell, the heat exchanger bracket has a top support plate, and the outer shell also has a fan assembly, the fan assembly includes a motor, a motor bracket and a fan blade driven to rotate by the motor, the motor bracket is a plate body, and the top support plate has a support through hole, the plate body is mounted on the top wall of the orifice of the support through hole so that the fan assembly can be hoisted on the top support plate through the plate body.

[0005] In some embodiments, the fan assembly further includes a connecting cover, which is disposed on a side of the motor facing the fan blades and is connected to the motor bracket.

[0006] In some embodiments, the heat exchanger bracket further has a connecting plate connected to the surrounding area of ​​the top support plate and extending downward, and the side heat exchanger is connected to the connecting plate; and / or, the top wall of the orifice of the supporting through hole has an annular sink, and the plate body is seated in the annular sink.

[0007] In some embodiments, the connecting plate has a bottom supporting portion extending toward the inner side of the heat exchanger bracket, and the bottom of the side heat exchanger is connected to the bottom supporting portion.

[0008] In some embodiments, a top heat exchanger is further mounted on the top support plate.

[0009] In some embodiments, the heat exchanger support further comprises a surrounding plate connected to the surrounding area of ​​the top support plate and extending upward, and the top heat exchanger seat is installed in the area surrounded by the surrounding plate.

[0010] In some embodiments, the fan assembly further includes an air guide housing, which is located on a side of the fan blade away from the motor, and an air duct of the side heat exchanger is formed between the air guide housing and the connecting plate.

[0011] In some embodiments, a water receiving tray component is further connected to the heat exchanger bracket, and the air guide housing is placed on the upper side of the water receiving tray component.

[0012] In some embodiments, the outer shell includes a top shell for ceiling assembly and a bottom shell detachably connected to the bottom of the top shell, and the water tray component is placed on the bottom shell.

[0013] In some embodiments, the top shell is provided with an air inlet, and the bottom shell is provided with an air outlet.

[0014] In some embodiments, the air outlet includes a side air outlet and a central air outlet, and the fan blade is a mixed flow fan blade. The axial outflow airflow driven by the fan blade can flow to the central air outlet through the air guide cover and the water receiving tray component in sequence, and the radial outflow airflow driven by the fan blade can flow to the side air outlet through the side heat exchanger and the water receiving tray component in sequence.

[0015] The present invention provides a ceiling-mounted air conditioner. Since the motor bracket is a plate and is supported on the top wall of the opening of the supporting through hole by a seat-mounted manner, the fan assembly occupies a smaller height in its axial direction by such a fixing method, which can save a large height space of the ceiling-mounted air conditioner. The overall thickness of the ceiling-mounted air conditioner is smaller. After being installed in the preset space, the ceiling-mounted air conditioner occupies a smaller height of the space, thereby increasing the effective space. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figures 1 to 5As shown, according to an embodiment of the present invention, a ceiling-mounted air conditioner is provided, including an outer shell body (not marked in the figure) for ceiling assembly, a heat exchanger bracket 1 is connected to the outer shell body, the heat exchanger bracket 1 is used to support and place the heat exchanger, the heat exchanger bracket 1 has a top support plate 11, and the outer shell body also has a fan assembly (not marked in the figure), the fan assembly includes a motor 21, a motor bracket 23 and a fan blade 22 driven to rotate by the motor 21, the motor bracket 23 is a plate body, and a support through-hole 12 is provided on the top support plate 11. The plate body is mounted on the top wall of the orifice of the support through-hole 12 so that the fan assembly can be hoisted on the top support plate 11 through the plate body. It can be understood that after the plate body is mounted on the support through-hole 12, there should be a ventilation structure between the two for the running airflow to flow through the support through-hole 12. In this technical solution, since the motor bracket 23 is a plate body and is supported on the top wall of the opening of the support through hole 12 by a seat-mounted manner, the fan assembly occupies a smaller height in its axial direction by adopting such a fixing method (for example, only the sum of the thickness of the plate body and the thickness of the top support plate 11). In this way, the ceiling-mounted air conditioner can save a large amount of height space, the overall thickness of the ceiling-mounted air conditioner is smaller, and the ceiling-mounted air conditioner occupies a smaller height of the preset space after being installed in the preset space, thereby increasing the effective space. The aforementioned ventilation structure is specifically, for example, a first ventilation hole (not shown in the figure) directly constructed on the plate body. The aforementioned plate body seat-mounted specifically refers to the plate body being overlapped on the top wall of the opening in an overlapping manner. This seating connection method is very simple and convenient. In some embodiments, the overlapped plate body and the top support plate 11 can also be positioned by bolts and other connectors.

[0024] In some embodiments, the fan assembly further includes a connecting housing 24, which is disposed on the side of the motor 21 facing the fan blades 22 and is connected to the motor bracket 23, thereby achieving the fixation of the motor 21 on the motor bracket 23. Figure 1 As shown, the connecting housing 24 is located on the lower side of the plate body of the motor bracket 23, but the motor 21 is located on the upper side of the connecting housing 24. When the motor 21 needs to be disassembled for maintenance, the connecting housing 24 can be removed or assembled from the lower side of the motor bracket 23, which is convenient and quick. In another preferred embodiment, the top wall of the opening of the support hole 12 has an annular sink, and the plate body is installed in the annular sink. This can effectively ensure the stable and accurate position of the fan assembly.

[0025] See Figure 3As shown, the heat exchanger support 1 also has a connecting plate 15 connected to the surrounding area of ​​the top support plate 11 and extending downward. The side heat exchanger 100 is connected to the connecting plate 15. Four side heat exchangers 100 can be provided, and the four side heat exchangers 100 are respectively arranged on the four sides of the top support plate 11. Of course, only two side heat exchangers 100 can also be provided, and the two side heat exchangers 100 are symmetrically arranged on both sides of the top support plate 11. By arranging multiple side heat exchangers 100 in the surrounding area, the heat exchange area of ​​the airflow can be increased, and the heat exchange efficiency and heat exchange effect can be improved. Furthermore, the connecting plate 15 has a bottom support portion 13 extending toward the inside of the heat exchanger support 1. The bottom of the side heat exchanger 100 is connected to the bottom support portion 13. In this way, the connecting plate 15 is roughly L-shaped in appearance, and the side heat exchanger 100 can be more stably and reliably mounted on the horizontal bottom support portion 13. In another preferred embodiment, a second vent is provided on the bottom support portion 13 to ensure smooth outflow of the heat exchange airflow to a certain extent.

[0026] In some embodiments, a top heat exchanger 101 is mounted on the top support plate 11. Specifically, the top heat exchanger 101 is positioned on the air inlet side of the fan assembly, further increasing the heat exchange area of ​​the airflow and thereby improving heat exchange efficiency and effectiveness. The heat exchanger bracket 1 also includes an upwardly extending enclosure 14 connected to the perimeter of the top support plate 11. The top heat exchanger 101 is mounted within the area enclosed by the enclosure 14. The enclosure of the enclosure 14 guides the air intake path of the top heat exchanger 101, thereby reducing intake noise.

[0027] See also Figure 1 As shown, the fan assembly also includes an air guide shell 25, which is located on the side of the fan blade 22 away from the motor 21. An air duct of the side heat exchanger 100 is formed between the air guide shell 25 and the connecting plate 15, so that the airflow driven by the fan blade 22 can be at least partially guided to the side heat exchanger 100 for heat exchange.

[0028] In some embodiments, a water pan assembly 3 is further connected to the heat exchanger bracket 1 for receiving condensed water generated by the side heat exchanger 100 and the top heat exchanger 101 above it. The air guide housing 25 is placed on the upper side of the water pan assembly 3. The aforementioned water pan assembly 3 specifically includes a condensed water guide assembly and a water pan for holding and draining the condensed water guided by the condensed water guide assembly. The condensed water guide assembly is arranged in the area below the side heat exchanger 100 and the top heat exchanger 101, and specifically includes an upper drainage component and a lower drainage component. The vents on the upper drainage component and the vents on the lower drainage component are horizontally staggered, so as to guide the condensed water while allowing air to pass through and out.

[0029] The outer shell includes a top shell 201 for ceiling assembly and a bottom shell 202 detachably connected to the top shell 201 (for example, by corresponding bolts). The water receiving tray component 3 is placed on the bottom shell 202, that is, the bottom shell 202 serves as a supporting component for the water receiving tray component 3. When it is necessary to maintain the internal components such as the fan assembly, the bottom shell 202 can be removed from the top shell 201. At this time, the water receiving tray component 3 will be removed along with the removal of the bottom shell 202. Since the air guide cover 25 is directly placed on the top surface of the water receiving tray component 3, that is, the air guide cover 2 5 is not connected to other components. Thus, after the bottom housing 202 is removed, the fan components are directly exposed to the user, enabling quick maintenance of the fan components. For example, the fan blades 22 can be further removed from the motor 21 for cleaning and maintenance (such as cleaning oil, dust, and other dirt). Of course, the connecting cover 24 can also be removed from the motor bracket 23, and the motor 21 can be disassembled for repair and other maintenance operations, greatly reducing the difficulty of fan component maintenance. During this process, each heat exchanger is connected to the outer shell through the heat exchanger bracket 1. A filter 4 can also be installed in the area between the water receiving tray component and the air outlet panel 6 to ensure the cleanliness of the outlet airflow.

[0030] The top shell 201 is provided with an air inlet, and the bottom shell 202 is provided with an air outlet. Specifically, the bottom shell 202 includes an air outlet panel 6, and the air outlet is constructed on the air outlet panel 6, so that the air conditioner can be inletted from above and outletd from below, effectively preventing short circuit of the heat exchange airflow.

[0031] In a preferred embodiment, the air outlet includes a side air outlet 203 and a central air outlet 204, and the fan blade 22 is a mixed flow fan blade. The aforementioned mixed flow fan blade means that its air flow has both an axial flow part and a radial flow part. In this way, the axial outflow airflow driven by the fan blade 22 can flow to the central air outlet 204 through the air guide cover 25 and the water receiving tray component 3 in sequence, and the radial outflow airflow driven by the fan blade 22 can flow to the side air outlet 203 through the side heat exchanger 100 and the water receiving tray component 3 in sequence. Figure 1 As indicated by the middle arrow, the air conditioner achieves wide-area air discharge, ensuring efficient temperature control of the target temperature-controlled space. The side air outlets 203 are provided with air guide plates, and the central air outlet 204 is provided with an air outlet grille 5. By controlling the deflection angle of the air guide plates or the air outlet grille 5, the air outlet angle can be adjusted, enhancing the user experience and comfort.
