[0008] The embodiments of the present disclosure provide a ceiling-mounted air conditioner to improve the usage scenarios of the ceiling-mounted air conditioner and meet various usage needs of users.

[0009] An embodiment of the present disclosure provides a ceiling-mounted air conditioner, which includes: a shell, which defines a accommodating cavity with an air inlet and an air outlet, the air inlet is arranged on the bottom wall of the shell, and the air outlet is arranged on the front side wall of the shell; a temperature control component, including a cross-flow fan and a heat exchanger, is located in the accommodating cavity, and the fan can drive the airflow at the air inlet to flow through the heat exchanger and then flow out from the air outlet; wherein the number of the cross-flow fans is multiple, and at least two of the multiple cross-flow fans are arranged in sequence along the length direction of the shell.

[0010] The ceiling-mounted air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] In the ceiling-mounted air conditioner of the disclosed embodiment, the air inlet is arranged on the bottom wall of the ceiling-mounted air conditioner housing, so that the top of the ceiling-mounted air conditioner does not need to be inlet, so that no space needs to be reserved at the top when the ceiling-mounted air conditioner is installed, and the ceiling-mounted air conditioner can be installed on the ceiling or suspended ceiling, which can not only reduce the installation space of the ceiling-mounted air conditioner, but also improve the sense of integration of the ceiling-mounted air conditioner home decoration, and solve the pain points of the installation of wall-mounted air conditioners. A heat exchanger and a cross-flow fan are arranged in the ceiling-mounted air conditioner, and the cross-flow fan is used to drive the air flow in the accommodating cavity. Two cross-flow fans are arranged, and the two cross-flow fans are arranged in sequence along the length direction of the housing, so that the length direction of the ceiling-mounted air conditioner can be increased, thereby increasing the air outlet range and air outlet length of the ceiling-mounted air conditioner. When the ceiling-mounted air conditioner is installed in a large space or corresponds to multiple spaces, the setting of multiple cross-flow fans can increase the air outlet area, or, match different spaces to control the work of different cross-flow fans, and improve the air outlet volume, air outlet range and air outlet flexibility of the ceiling-mounted air conditioner. In this way, when the indoor space is large, there is no need to install multiple ceiling-mounted air conditioners, one ceiling-mounted air conditioner can meet the temperature control needs.

When the telescopic rod 301 is extended, the telescopic rod 301 can drive the air inlet guide plate 104 to move to open the air inlet 101. When the telescopic rod 301 is retracted, it can drive the air inlet guide plate 104 to move in the opposite direction so that the air inlet guide plate 104 closes the air inlet 101. The telescopic rod 301 moves stably and can realize the automatic opening and closing of the air inlet guide plate 104. Optionally, the telescopic rod 301 is an electric telescopic rod 301 or a cylinder telescopic rod 301.

[0047] Optionally, the telescopic rod 301 is an electric telescopic rod 301 or a cylinder telescopic rod 301 .

[0048] Optionally, the air inlet drive mechanism further includes a rotating member 302, which is rotatably connected to the telescopic end of the telescopic rod 301; wherein the rotating member 302 is connected to the air inlet guide plate 104, and the telescopic rod 301 can drive the rotating member 302 to rotate to drive the air inlet guide plate 104 to rotate.

[0049] In the disclosed embodiment, the telescopic end of the telescopic rod 301 is rotatably connected to the rotating member 302, and the rotating member 302 is connected to the air inlet guide plate 104, so that when the telescopic rod 301 is extended or retracted, the telescopic rod 301 can drive the rotating member 302 to rotate, and the rotating member 302 further drives the air inlet guide plate 104 to rotate, so as to realize the opening or closing of the air inlet guide plate 104.

[0050] Alternatively, if Figure 4 and Figure 6 As shown, the air inlet driving mechanism further includes a rotating shaft 303 , which is connected to the air inlet guide plate 104 , and the rotating shaft 303 is disposed in the accommodating cavity 103 , and the rotating member 302 is rotatably connected to the rotating shaft 303 .

[0053] In the embodiment of the present disclosure, the rotating member 302 is rotatably connected to the rotating shaft 303, and the rotating shaft 303 can move in the vertical direction, so that when the telescopic rod 301 is extended, the telescopic rod 301 first drives the rotating member 302 and the rotating shaft 303 to move downward, and when the rotating shaft 303 moves downward to the preset position, the rotating shaft 303 drives the air inlet guide plate 104 to move downward first. When the rotating shaft 303 moves downward to the preset position, the rotating shaft 303 cannot continue to move downward, and the telescopic rod 301 continues to apply a downward force to the rotating member 302, so that the rotating member 302 rotates, and at the same time, the rotating member 302 can drive the rotating shaft 303 to rotate, so that the rotation drives the air inlet guide plate 104 to rotate, and then the air inlet guide plate 104 is opened. When it is necessary to close the air inlet guide plate 104, the telescopic rod 301 contracts, first driving the rotating member 302 to rotate in the opposite direction, so that the air inlet guide plate 104 is first rotated to a horizontal position, and then the telescopic rod 301 drives the rotating shaft 303 and the air inlet guide plate 104 to rise, so that the air inlet guide plate 104 can cover the air inlet 101, thereby closing the air inlet 101.

[0054] Optionally, the air inlet drive mechanism further includes a connecting plate 304, the connecting plate 304 is located in the accommodating cavity 103, the upper end of the connecting plate 304 is connected to the rotating shaft 303, and the lower end of the connecting plate 304 is connected to the air inlet guide plate 104.

The rotating member 302 and the air inlet guide plate 104 are connected through the connecting shaft and the connecting plate 304. When the telescopic rod 301 is extended, the rotating member 302 rotates toward the first direction, and then drives the connecting shaft to rotate, and the connecting shaft drives the connecting plate 304 to rotate, and the connecting plate 304 can drive the air inlet guide plate 104 to rotate, so as to open the air inlet guide plate 104. When the telescopic rod 301 contracts, the telescopic rod 301 drives the rotating member 302 to rotate in a second direction opposite to the first direction, thereby driving the connecting shaft connected to the rotating member 302 to rotate, and the connecting shaft drives the connecting plate 304 to rotate to close the air inlet guide plate 104.

[0058] Alternatively, if Figure 4 As shown, the rotating member 302 includes a first connecting arm 3021, a second connecting arm 3022 and a third connecting arm 3023. One end of the first connecting arm 3021 is sleeved on the outside of the rotating shaft 303; one end of the second connecting arm 3022 is rotatably connected to the telescopic end of the telescopic rod 301; the third connecting arm 3023 is connected between the other end of the first connecting arm 3021 and the other end of the second connecting arm 3022.

[0059] In the disclosed embodiment, the first connecting arm 3021 of the rotating member 302 can rotate around the rotating axis 303, and the second connecting arm 3022 is connected to the telescopic end and the connecting axis of the telescopic rod 301, so that when the telescopic rod 301 is extended or retracted, the rotating member 302 can be driven to rotate around the rotating axis 303.

[0060] Optionally, the first connecting arm 3021 and the second connecting arm 3022 extend toward both sides of the third connecting arm 3023 respectively, that is, the extending directions of the first connecting arm 3021 and the second connecting arm 3022 are opposite, which facilitates the arrangement of the telescopic rod 301 and the rotating shaft 303.

[0061] Optionally, the rotating member 302 is Z-shaped.

[0062] Optionally, when the air intake drive mechanism includes a connecting shaft, the connecting shaft and the telescopic end of the telescopic rod 301 are sequentially arranged at intervals along the extension direction of the second connecting arm 3022 .

[0063] In the disclosed embodiment, the connecting shaft and the telescopic rod 301 are both arranged on the second connecting arm 3022 and are arranged separately, so that the connecting shaft will not interfere with the pushing effect of the telescopic rod 301 on the rotating member 302, and the rotating member 302 will not affect the connection between the connecting shaft and the connecting plate 304.

[0064] Optionally, the rotating shaft 303 is connected to the bottom of the first connecting arm 3021, the telescopic rod 301 is connected to the top of the second connecting arm 3022, and the first connecting arm 3021 is located above the second connecting arm 3022. When the telescopic rod 301 is in the retracted position, the telescopic rod 301 is located on one side of the third connecting arm 3023, and there is a gap between the third connecting arm 3023 and the telescopic rod 301.

[0065] In the embodiment of the present disclosure, when the telescopic rod 301 is extended, the rotating member 302 rotates clockwise, and there is a gap between the telescopic rod 301 and the third connecting arm 3023, which can prevent the telescopic rod 301 from hindering the rotation of the rotating member 302. In addition, when the rotating member 302 rotates to a certain angle, the telescopic rod 301 can limit the third connecting arm 3023 to prevent the rotating member 302 from rotating too far, so as to prevent the air inlet guide plate 104 from rotating too much, thereby protecting the air inlet guide plate 104.

[0066] Optionally, when the telescopic rod 301 is contracted, the telescopic rod 301 extends in the vertical direction, and the fixed end of the telescopic rod 301 is rotatably connected to the top wall 107 of the housing 10 .

[0067] In the disclosed embodiment, when the telescopic rod 301 is retracted, the air inlet guide plate 104 is in a closed state, and the telescopic rod 301 extends in a vertical direction, which facilitates the setting of the telescopic rod 301. When the telescopic rod 301 is extended, the telescopic rod 301 can push the rotating member 302 to rotate, and the telescopic rod 301 also rotates to avoid getting stuck.

[0068] Optionally, there are multiple air inlet drive mechanisms, and the multiple air inlet drive mechanisms are sequentially spaced along the length direction of the air inlet 101. In the embodiment of the present disclosure, when the length of the air inlet 101 is long, one or more air inlet guide plates 104 may be provided, and one or more air inlet guide plates 104 are correspondingly provided with multiple air inlet drive mechanisms, which can improve the movement stability of the air inlet guide plates 104.

[0069] Optionally, there are multiple telescopic rods 301 , the number of rotating members 302 is the same as and corresponds to the number of telescopic rods 301 , and the multiple telescopic rods 301 are sequentially spaced apart along the length direction of the air inlet 101 .

[0070] In the disclosed embodiment, the rotating shaft 303 extends along the length direction of the shell 10. When the length of the air inlet 101 is longer, the length of the rotating shaft 303 is also longer. The multiple telescopic rods 301 are arranged in sequence at intervals along the length direction of the rotating shaft 303. Correspondingly, the multiple rotating members 302 corresponding to the multiple telescopic rods 301 are also arranged in sequence at intervals along the length direction of the rotating shaft 303. In this way, the air inlet guide plate 104 connected to the multiple rotating members 302 can move synchronously to improve the stability of opening and closing of the air inlet guide plate 104.

[0071] Optionally, there are multiple connecting plates 304, and the multiple connecting plates 304 are sequentially spaced along the length direction of the air inlet guide plate 104. In the embodiment of the present disclosure, multiple connecting plates 304 are provided, which can increase the connection area between the air inlet drive mechanism and the air inlet guide plate, thereby enabling the air inlet guide plate 104 to move synchronously even when the length is long.

[0072] Optionally, the cross-sectional area of ​​the lower end of the connecting plate 304 is larger than the cross-sectional area of ​​the upper end of the connecting plate 304 , so as to increase the connection area between the connecting plate 304 and the guide plate of the air inlet 101 .

[0073] In the embodiment of the present disclosure, the cross-sectional area of ​​one end of the connecting plate 304 connected to the air inlet guide plate 104 is larger than the cross-sectional area of ​​the other end of the connecting plate 304. This can increase the connection area between the connecting plate 304 and the air inlet guide plate 104, thereby increasing the driving effect of the connecting plate 304 on the air inlet guide plate 104 and improving the movement stability of the air inlet guide plate 104.

[0074] Optionally, the lower end of the connecting plate 304 is connected to both sides of the axis of the air inlet guide plate 104 , so that the connecting plate 304 can simultaneously drive both sides of the axis of the air inlet guide plate 104 to move, thereby improving the rotation efficiency of the air inlet guide plate 104 .

[0075] Optionally, the shell assembly for the air conditioner also includes an air outlet adjustment device, which is movably arranged at the air outlet and is used to adjust the air outlet volume and / or air outlet direction of the air outlet to further improve the air outlet effect of the air conditioner.

[0076] In some optional embodiments, such as Figures 7 to 11 As shown, in some optional embodiments, as Figures 7 to 11As shown, the housing assembly for the air conditioner further includes an air outlet guide plate 105 and an air outlet drive mechanism. The air outlet guide plate 105 is movably disposed at the air outlet 102 for opening or closing the air outlet 102. The air outlet drive mechanism 40 is drivingly connected to the air outlet guide plate 105. The air outlet drive mechanism 40 can drive the air outlet guide plate 105 to slide between a first position and a second position relative to the housing 10. When the air outlet guide plate 105 is in the first position, the air outlet guide plate 105 is at least partially received in the accommodating cavity 103 to open the air outlet 102; when the air outlet guide plate 105 is in the second position, the air outlet guide plate 105 is covered on the front side of the air outlet 102 to close the air outlet 102. Among them, the air outlet adjustment device includes the air outlet guide plate 105.

[0077] In the disclosed embodiment, the air outlet guide plate 105 can open or close the air outlet 102, so that when the air conditioner is not working, the air outlet guide plate 105 can close the air outlet 102 to prevent dust from entering the air outlet 102 and affecting the air volume of the air outlet 102. The air outlet guide plate 105 can slide between the first position and the second position under the driving action of the air outlet drive mechanism 4040. The sliding setting of the air outlet guide plate 105 requires a smaller movement space than the rotating setting. Therefore, the air outlet guide plate 105 can be slid into the housing 10 and hidden. In this way, the air outlet guide plate 105 will not occupy the space of the air outlet 102, nor will it affect the air volume of the air outlet 102.

When the mounting plate 90 is connected to the shell 10, the mounting plate 90 is at least partially located in the mounting groove 904. This allows the top wall 107 of the shell 10 to be as close to the ceiling as possible, thereby reducing the gap between the ceiling and the top wall 107 of the shell 10, improving the aesthetics of the installation, and preventing dust from accumulating on the top wall 107 of the shell 10.

[0130] Optionally, the ceiling mounted air conditioner further comprises a temperature control component, which comprises a fan 202 and a heat exchanger 201, and is located in the accommodating cavity 103. The fan 202 can drive the air flow from the air inlet 101 to flow through the heat exchanger 201 and then flow out from the air outlet 102. In this way, the ceiling mounted air conditioner can blow out cold air or hot air to adjust the indoor temperature.

[0131] Optionally, the fan 202 is a cross-flow fan, which can increase the air volume of the ceiling air conditioner and thus improve the temperature control effect.

In this way, the airflow flowing into the air inlet 101 first exchanges heat with the heat exchanger 201, then flows through the fan 202, and then flows out from the air outlet 102. The air inlet 101, the heat exchanger 201, the fan 202 and the air outlet 102 are arranged in sequence from the back to the front, that is, the air inlet 101 is arranged at the back, so that the airflow flowing into the air inlet 101 has enough path to flow through the heat exchanger 201, thereby increasing the heat exchange time with the heat exchanger 201 and improving the heat exchange efficiency.

[0134] Alternatively, if Fig.14 As shown, there are multiple crossflow fans, and at least two of the multiple crossflow fans are arranged in sequence along the length direction of the housing 10. This can not only increase the air volume of the crossflow fans, but also increase the size of the ceiling air conditioner and the installation flexibility of the ceiling air conditioner. It is also possible to independently control the opening and closing of each crossflow fan to increase the diversity of the air output of the ceiling air conditioner and improve the user experience.

[0135] Optionally, from front to back, the heat exchanger 201 is tilted upward, and part of the evaporator is located above the air inlet 101. This can increase the heat exchange area between the heat exchanger 201 and the airflow, thereby improving the temperature adjustment effect of the ceiling air conditioner. Part of the evaporator is located above the air inlet 101, so that the airflow flowing into the air inlet 101 can flow to the heat exchanger 201, further increasing the heat exchange area between the heat exchanger 201 and the air inlet 101.

[0136] Optionally, along the direction from top to bottom, the projection of the heat exchanger 201 is located inside the air inlet 101, and the upper end of the heat exchanger 201 abuts against the top wall 107 of the shell 10, so that the airflow flowing into the air inlet 101 must flow through the heat exchanger 201 and then flow to the air outlet 102, ensuring that the airflow flowing into the air inlet 101 can fully exchange heat, thereby improving the temperature control effect of the ceiling air conditioner.

[0137] Optionally, the height of the accommodating chamber 103 decreases from the back to the front. Since the air outlet 102 is arranged on the front side wall 108 and the air inlet 101 is arranged on the rear side of the bottom wall, the flow area of ​​the accommodating chamber 103 decreases as it approaches the air outlet 102, which can increase the air outlet speed of the air outlet 102. In addition, the reduced area of ​​the air outlet 102 is also convenient for setting up an air outlet device. Optionally, the bottom wall of the shell 10 extends in the horizontal direction, and the distance between the top wall 107 of the shell 10 and the bottom wall of the shell 10 gradually decreases from the back to the front, so that the components in the shell 10 can be stably placed and the changes of the accommodating chamber 103 can be realized.

[0138] Optionally, the ceiling air conditioner also includes a driving device, which is located on one side of the crossflow fan and is used to drive the crossflow fan to rotate; wherein the number of the driving devices is the same as the number of the crossflow fans and corresponds one to one.

[0139] In the disclosed embodiment, each cross-flow fan is provided with a driving device, so that each cross-flow fan can be independently controlled to open or close or rotate speed, which can improve the air outlet diversity of the ceiling-mounted air conditioner.

[0140] Optionally, there are multiple air outlets 102, and the number of air outlets 102 is the same as the number of crossflow fans and corresponds one to one, so that the air volume of each air outlet 102 can be controlled individually, thereby improving the usage diversity of the ceiling air conditioner.

[0141] Optionally, the ceiling air conditioner further includes a detection device and a controller, wherein the detection device is used to detect the temperature information of the indoor environment; the controller is electrically connected to the detection device and the plurality of driving devices, and the controller is configured to control the operation of the plurality of driving devices according to the temperature information of the indoor environment. This enables the ceiling air conditioner to automatically adjust the air outlet mode, improves the intelligent adjustment of the ceiling air conditioner, and improves the user experience.

[0142] Alternatively, if Fig.15As shown, the ceiling air conditioner also includes a volute 2021 and a volute tongue 2022. The volute 2021 is located above the crossflow fan; the volute tongue 2022 is arranged on the bottom wall of the housing 10 and is located on the side of the crossflow fan facing the air outlet 102. The volute 2021 and the volute tongue 2022 define a fan cavity with an inlet and an outlet; wherein one end of the volute 2021 extends to the side of the crossflow fan facing the heat exchanger 201, and the outlet is inclined downward from the back to the front. In the embodiment of the present disclosure, a crossflow fan is installed in the fan cavity, and the volute 2021 and the volute tongue 2022 cooperate with the crossflow fan to adjust the air outlet direction of the crossflow fan so that the airflow can flow from the rear side of the crossflow fan to the front side. One side of the volute 2021 extends to the side of the crossflow fan facing the heat exchanger 201, so that the heat exchanger 201 flowing out can flow into the fan cavity, pass through the inside of the crossflow fan, and flow out from the lower part of the crossflow fan along the radial direction of the crossflow fan, so that the airflow flowing out of the crossflow fan can flow out from the air outlet 102. Since the bottom wall of the shell 10 extends horizontally, the distance between the top wall 107 of the shell 10 and the top wall 107 of the shell 10 and the bottom wall of the shell 10 gradually decreases from the back to the front direction, and the outlet of the crossflow fan is inclined downward from the back to the front direction, so that the outlet of the crossflow fan can cooperate with the air outlet 102, increase the air volume of the air outlet 102, and reduce the loss of air volume.

[0143] Optionally, the ceiling air conditioner further comprises a reinforcing rib 2023, which is arranged on a side of the volute 2021 away from the fan chamber. This can improve the strength of the volute 2021 and prevent the volute 2021 from deforming.

[0144] Optionally, there are multiple reinforcing ribs 2023 , and the multiple reinforcing ribs 2023 are arranged in sequence and at intervals along the length direction of the volute 2021 , which can further enhance the strength of the volute 2021 .

[0145] Optionally, the air outlet drive mechanism is arranged on the volute.

[0146] In the disclosed embodiment, the air outlet drive mechanism is disposed on the volute, which can increase the installation height of the air outlet drive mechanism so that the air outlet drive mechanism can drive the air outlet adjustment structure to move.

[0147] Optionally, when there are multiple air outlets, the multiple air outlets are sequentially spaced apart along the length direction of the housing, so as to avoid mutual interference between airflows of adjacent air outlets and improve the air outlet effect.
