[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 on 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 wall-mounted air conditioner installation. An air inlet guide plate is arranged at the air inlet, and the air inlet guide plate can be pushed and pulled to open or close the air inlet, so that when the ceiling-mounted air conditioner is not working, the air inlet can be closed to prevent dust from entering the air inlet and affecting the air intake. The air inlet guide plate can be pushed and pulled at the air inlet, which improves the aesthetics of the air inlet guide plate when it is opened, and can increase the movement stability of the air inlet guide plate. The air inlet is arranged tilted, so that the air inlet guide plate is also arranged tilted, which can reduce the space occupied by the air inlet guide plate in the upper and lower directions when it is opened, save the space under the ceiling-mounted air conditioner, and improve the installation convenience of the ceiling-mounted air conditioner.

[0031] For ease of description, the front and back directions of this application are as follows Figure 1 shown.

[0032] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides a ceiling-mounted air conditioner, which includes a housing 10, the housing 10 defines a receiving cavity 103 having an air inlet 101 and an air outlet 102, the air inlet 101 is arranged on the bottom wall of the housing 10, and the air outlet 102 is arranged on the front side wall of the housing 10. The top wall of the housing is against the ceiling or suspended ceiling.

[0033] In the disclosed embodiment, the air inlet 101 of the ceiling-mounted air conditioner is arranged on the bottom wall of the shell 10, and the air outlet 102 is arranged on the front side wall of the shell 10. In this way, the top wall 107 of the ceiling-mounted air conditioner can be set against the ceiling or the suspended ceiling. No space needs to be reserved on the top of the ceiling-mounted air conditioner, which improves the aesthetics of the installation of the ceiling-mounted air conditioner and the sense of integration with the home decoration.

[0034] Optionally, the ceiling air conditioner further includes a temperature control component, which includes 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 through the heat exchanger 201 and then out of the air outlet 102 .

[0035] In the disclosed embodiment, the temperature control component is located in the accommodating cavity 103, and the fan 202 can drive the air flow at the air inlet 101 to flow through the heat exchanger 201, and flow out from the air outlet 102 after heat exchange with the heat exchanger 201, so that the air conditioner can blow out cold air or hot air to adjust the indoor temperature.

[0036] Optionally, the fan 202 is a cross-flow fan, which can increase the air volume of the air conditioner and thus improve the temperature control effect.

[0037] Optionally, the length of the cross-flow fan extends along the length direction of the housing 10 to reduce the dimensions of the air conditioner in other directions and facilitate the installation of the air conditioner.

[0038] Optionally, there are multiple cross-flow fans, and at least two of the multiple cross-flow fans are sequentially arranged along the length direction of the housing 10 .

[0039] In the disclosed embodiment, there are multiple crossflow fans, which 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. The opening and closing of each crossflow fan can also be independently controlled to increase the diversity of the air output of the ceiling air conditioner and improve the user experience.

[0040] Optionally, the ceiling-mounted air conditioner also includes an air inlet guide plate 104, which can be pushed and pulled and is arranged at the air inlet 101; wherein, the air inlet guide plate 104 can be pushed and pulled between an open position and a closed position, and when the air inlet guide plate 104 moves from a closed position toward an open position, the air inlet guide plate 104 moves in a direction away from the air inlet 101 to open the air inlet 101; when the air inlet guide plate 104 moves from an open position toward a closed position, the air inlet guide plate 104 moves in a direction close to the air inlet 101 to close the air inlet 101.

[0041] In the disclosed embodiment, the air inlet guide plate 104 can be pushed and pulled at the air inlet 101. When the air inlet guide plate 104 is in the closed position, the air inlet guide plate 104 covers the outside of the air inlet 101 to close the air inlet 101. When the air inlet guide plate 104 is in the open position, the air inlet guide plate 104 is located at the outside of the air inlet 101 and is spaced from the air inlet 101. The air inlet guide plate 104 and the air inlet 101 form an air inlet gap, and the indoor airflow flows into the air inlet 101 from the air inlet gap.

[0042] Optionally, the air inlet is arranged at an angle, so that the air inlet guide plate can also move in the inclined direction, thereby reducing the space occupied under the ceiling-mounted air conditioner and improving the installation convenience of the ceiling-mounted air conditioner.

[0043] Optionally, the air inlet is tilted downward from the back to the front, or the air inlet is tilted upward from the back to the front, so that the air inlet guide plate can move a certain distance in the front-to-back direction, reducing the movement space in the vertical direction.

[0044] It should be noted that the air inlet may also be inclined in the left-right direction or in other directions, and any arrangement that can reduce its movement space in the height direction belongs to an optional embodiment of the present application.

[0045] Optionally, when the air inlet guide plate 104 is in the closed position, the side wall of the air inlet guide plate 104 abuts against the side wall of the air inlet 101 to close the air inlet 101. When the air inlet 101 is in the open position, the air inlet gap formed by the air inlet guide plate 104 and the air inlet 101 extends along the circumference of the air inlet guide plate 104, so that the air flow can enter the air inlet 101 from all around the air inlet guide plate 104 to ensure the air intake. Optionally, the air inlet gap is in a ring shape extending along the circumference of the air inlet guide plate 104.

[0046] Optionally, the cross-sectional area of ​​the air inlet guide plate 104 is larger than the cross-sectional area of ​​the air inlet 101, and when the air inlet guide plate 104 is in the closed position, the air inlet guide plate 104 is attached to the wall surface of the bottom wall away from the accommodating cavity 103. In this way, the air inlet 101 can be better closed.

[0047] Optionally, when the air inlet guide plate 104 is in the open position, the air inlet guide plate 104 is parallel to the air inlet 101. In this way, when the air inlet guide plate 104 is toward the closed position, it is convenient to control the air inlet guide plate 104.

[0048] Optionally, the bottom wall of the shell 10 includes a first bottom wall section 203, a second bottom wall section 204 and a third bottom wall section 205, the first bottom wall section 203 extends in a horizontal direction, and the first bottom wall section 203 is located on the front side; the second bottom wall section 204 extends in a horizontal direction, and the second bottom wall section 204 is located on the rear side; the third bottom wall section 205 is connected between the first bottom wall section 203 and the second bottom wall section 204, and along the direction from front to back, the third bottom wall section 205 is inclined downward; wherein, the third bottom wall section 205 is provided with an air inlet 101.

[0049] In the disclosed embodiment, the air inlet 101 is provided at the third bottom wall section 205, and the third bottom wall section 205 is inclined downward in the direction from front to back. Thus, when the air inlet guide plate 104 is opened, it moves toward the front side and downward. When the air inlet guide plate 104 is closed, the air inlet guide plate 104 moves backward and forward, so that the air inlet guide plate 104 can close the air inlet 101. Among them, the second bottom wall section 204 is lower than the first bottom wall section 203, so that the accommodation cavity 103 corresponding to the second bottom wall section 204 has a larger space, and more devices can be placed.

[0050] Optionally, the angle between the third bottom wall section 205 and the horizontal direction ranges from 120° to 150°.

[0051] In the embodiment of the present disclosure, when the angle between the third bottom wall section 205 and the horizontal direction is less than 120°, the area of ​​the air inlet 101 is relatively small when the height dimension of the ceiling-mounted air conditioner is fixed. While ensuring the air inlet area of ​​the ceiling-mounted air conditioner, the height dimension of the ceiling-mounted air conditioner will increase, which is inconvenient for the installation of the ceiling-mounted air conditioner. When the angle between the third bottom wall section 205 and the horizontal direction is greater than 150°, the front-to-back dimension of the second bottom wall section 204 is reduced, or the dimension of the third bottom wall section 205 is larger, which is not conducive to the installation of the device in the accommodating cavity 103.

[0052] For example, the angle between the third bottom wall section 205 and the horizontal direction can be 120°, 125°, 130°, 135°, 137.5°, 140°, 145°, 150°, etc. Preferably, the angle between the third bottom wall section 205 and the horizontal square is 137.5°, which can ensure the area of ​​the air inlet 101, the space in the accommodating cavity 103 and the convenience of installation, and adopt this angle to beautify the appearance of the ceiling air conditioner to the greatest extent and improve the user experience.

[0053] Optionally, along the direction from front to back, the length of the first bottom wall section 203 is less than the length of the second bottom wall section 204. This makes the size of the accommodating cavity 103 corresponding to the second bottom wall section 204 larger in the front-to-back direction, which is convenient for arranging other components of the ceiling air conditioner.

[0054] Optionally, the ceiling-mounted air conditioner further includes an air inlet drive mechanism, which is drivingly connected to the air inlet guide plate 104 to drive the air inlet guide plate 104 to move.

[0055] In the disclosed embodiment, the air inlet guide plate 104 is driven to move by an air inlet driving mechanism, so that the air inlet guide plate 104 can automatically move between an open position and a closed position, thereby improving the intelligence of the movement of the air inlet guide plate 104 and further improving the user experience.

[0056] Optionally, the inclination direction of the air inlet guide plate 104 is the same as the inclination direction of the air inlet port 101, and the air inlet driving mechanism includes a push rod 206, which is connected to the air inlet guide plate 104, and the push rod 206 is located in the accommodating cavity 103. The push rod 206 can push the air inlet guide plate 104 to move between the open position and the closed position.

[0057] In the disclosed embodiment, the push rod 206 is connected to the air inlet guide plate 104, and the air inlet guide plate 104 has the same inclination direction as the air inlet 101. The push rod 206 can move in a direction perpendicular to the air inlet 101 so that the air inlet guide plate 104 can move toward and away from the air inlet 101.

[0058] Optionally, the push rod 206 is an electric push rod 206 or a cylinder push rod 206 .

[0059] Optionally, the push rod 206 includes a fixed shell and a push rod, the push rod is movably located in the fixed shell, and the push rod can be extended or retracted into the fixed shell. The fixed shell is connected to the housing 10 to fix the fixed shell, and the push rod is connected to the air inlet guide plate 104 to push the air inlet guide plate 104 to move.

[0060] Optionally, the temperature control component corresponds to the second bottom wall section 204, that is, the temperature control component is arranged above the second bottom wall section 204. Since the third bottom wall section 205 is inclined as described above, the air inlet 101 is arranged on the third bottom wall section 205, and the temperature control component is arranged above the second bottom wall section 204, so that the airflow flowing into the air inlet 101 can flow through the fan 202 and the heat exchanger 201 to realize heat exchange of the airflow.

[0061] Optionally, the heat exchanger 201 is located above the air inlet 101 , and along the direction from front to back, the heat exchanger 201 is tilted downward so that the heat exchanger 201 corresponds to the air inlet 101 .

[0062] In the disclosed embodiment, the heat exchanger 201 is located above the air inlet 101, so that the airflow flowing into the air inlet 101 can flow through the heat exchanger 201. The heat exchanger 201 is also tilted, which can increase the contact area between the heat exchanger 201 and the airflow, thereby improving the heat exchange effect of the heat exchanger 201.

[0063] Optionally, the fan 202 is located above the heat exchanger 201, and the ceiling air conditioner also includes a volute 2021 and a volute tongue 2022, the volute 2021 is located above the fan 202; the volute tongue 2022 is located on the side of the fan 202 facing the heat exchanger 201, the volute tongue 2022 and the volute 2021 enclose a fan cavity having an inlet and an outlet, and the inlet is connected to the heat exchanger 201; wherein, along the direction from front to back, the outlet is inclined upward.

[0064] In the disclosed embodiment, the volute 2021 and the volute tongue 2022 define a fan cavity, and the fan 202 is located in the fan cavity. The volute 2021 and the volute tongue 2022 cooperate to adjust the airflow direction in the fan cavity, downward, and the airflow flowing out of the heat exchanger 201 flows into the fan cavity from the inlet, then flows into the inside of the crossflow fan, and then flows out of the crossflow fan from the radial direction of the crossflow fan, and then flows from the outlet to the air outlet 102. The outlet is tilted upward in the direction from front to back, so that the airflow flowing out of the outlet can flow to the air outlet 102, thereby increasing the air volume and reducing the air volume loss.

[0065] Optionally, one end of the volute 2021 abuts against the rear wall of the casing 10 , and the other end of the volute 2021 extends to the front side of the fan 202 .

[0066] In the disclosed embodiment, one end of the volute 2021 abuts against the rear side wall of the housing 10, so that air leakage from between the volute 2021 and the rear side wall can be avoided, which affects the air volume. The other end of the volute 2021 extends to the front side of the fan 202, which can better guide the wind into the accommodating cavity 103 corresponding to the first bottom wall section 203, so that the airflow can flow out from the air outlet 102.

[0067] Optionally, an air outlet 102 is provided on the front side wall of the shell 10, and the top wall 107 of the shell 10 extends in a horizontal direction, so that the distance between the first bottom wall section 203 and the top wall 107 of the shell 10 is smaller than the distance between the second bottom wall section 204 and the top wall 107, so that the flow area of ​​the accommodating cavity 103 close to the air outlet 102 is reduced, the air outlet speed is increased, and the air outlet volume of the air outlet 102 is increased.

[0068] Optionally, the ceiling-mounted air conditioner also includes an air outlet adjustment device and an air outlet driving mechanism. The air outlet adjustment device is movably arranged at the air outlet 102, and is used to adjust the air outlet volume and air outlet direction of the air outlet 102; the air outlet driving mechanism is drivingly connected to the air outlet adjustment device, and is used to drive the air outlet adjustment device to move.

[0069] In the disclosed embodiment, the air outlet driving mechanism drives and the air outlet adjusting device, so that the air outlet of the air outlet 102 can also be adjusted, thereby improving the air outlet diversity of the ceiling air conditioner.

[0070] In some other optional embodiments, Figures 6 to 8 As shown, the housing assembly for the air conditioner includes a housing 10 and an air outlet guide plate 106, wherein the housing 10 defines a receiving chamber 103 having an air inlet 101 and an air outlet 102; the air outlet guide plate 106 is movably located at the air outlet 102, and is used to adjust the air outlet direction and air outlet volume of the air outlet 102; wherein the outer wall surface 1061 of the air outlet guide plate 106 is an arc surface, so that the airflow of the air outlet 102 can flow along the outer wall surface 1061 of the air outlet guide plate 106 to discharge air. wherein the air outlet regulating device includes the air outlet guide plate 106. the air outlet regulating device includes the air outlet guide plate 106.

[0071] In the disclosed embodiment, the air outlet guide plate 106 is movably located at the air outlet 102, so that when the air outlet guide plate 106 moves, the air outlet guide plate 106 can change the air outlet direction of the air outlet 102, thereby realizing the adjustment of the air outlet direction and the air volume. The outer wall surface 1061 of the air outlet guide plate 106 is an arc surface, so that when the airflow flowing out of the air outlet 102 flows through the air outlet guide plate 106, the arc surface can form a Coanda effect on the airflow, and the airflow will change the original path and flow along the outer wall surface 1061 of the air outlet guide plate 106. In this way, the air outlet guide plate 106 can not only adjust the air volume and air outlet direction, but also extend the guiding path of the airflow, increase the air supply distance, and improve the guiding effect of the air outlet guide plate 106 on the airflow of the air outlet 102, thereby improving the user experience.

[0072] The Coanda effect, also known as the wall adhesion or Coanda effect, is a fluid mechanics phenomenon, which means that when a fluid (such as water flow or air flow) encounters a protruding surface of an object, it will change its original flow direction and flow along the surface of the object.

[0073] Optionally, the opening of the curved surface faces the accommodating cavity 103, and the air outlet guide plate 106 can rotate between a first air guiding position and a second air guiding position. When the air outlet guide plate 106 is located at the first air guiding position, the lower end of the curved surface protrudes from the front side of the upper end of the curved surface to guide the airflow of the air outlet 102 to flow downward along the curved surface; when the air outlet guide plate 106 is located at the second air guiding position, the upper end of the curved surface protrudes from the front side of the lower end of the curved surface to guide the airflow of the air outlet 102 to flow upward along the curved surface.

[0074] In the embodiment of the present disclosure, the opening of the arc surface faces the accommodating cavity 103, that is, the arc surface protrudes in a direction away from the accommodating cavity 103. Figure 7 As shown, when the air outlet guide plate 106 rotates to the first air guiding position, the lower end of the arc surface protrudes from the front side of the upper end of the arc surface. It can be understood that the air outlet guide plate 106 is tilted downward from the back to the front at this time, and the opening of the arc surface faces the lower part of the accommodating cavity 103, so that the airflow of the air outlet 102 can not only be discharged downward under the action of the air outlet guide plate 106, but also flow along the outer wall surface 1061 of the air outlet guide plate 106, so that the angle between the airflow and the vertical direction is smaller, thereby allowing the airflow to flow further downward. When the air conditioner is heating, the airflow can fully flow to the lower part of the room to improve the heating range and heating uniformity. Figure 8As shown, when the air outlet guide plate 106 rotates to the second air guiding position, the upper end of the arc surface protrudes from the front side of the lower end of the arc surface, that is, along the direction from back to front, the arc surface is inclined upward, so that the airflow of the air outlet 102 can not only be discharged upward under the action of the air outlet guide plate 106, but also flow along the arc surface under the Coanda effect, so that the angle between the airflow flowing out of the air outlet 102 and the vertical direction is smaller, that is, the airflow is closer to the front side wall 108 of the housing 10, so that the flow distance of the airflow flowing out of the air conditioner is farther. When the air conditioner is cooling, the air guide plate moves to the second air guiding position, which can increase the flow distance of the cold air flow, improve the cooling effect and cooling range.

[0075] Optionally, the air outlet guide plate 106 can also be rotated to a closed position. When the air outlet guide plate 106 is in the closed position, the upper end and the lower end of the air outlet guide plate 106 are flush with each other to close the air outlet 102 .

[0076] In the disclosed embodiment, when the air conditioner does not need to discharge air, the air outlet guide plate 106 can be rotated to a closed position, so that the air outlet guide plate 106 can close the air outlet 102 to prevent external dust from entering the air outlet 102.

[0077] Optionally, there are multiple air outlet guides 106, and the multiple air outlet guides 106 are sequentially arranged at the air outlet 102 along the height direction. The air outlet 102 is provided with multiple air outlet guides 106, so that the width of each air outlet guide 106 is relatively small. When the air outlet 102 needs to discharge air, the rotation angle of each air outlet guide 106 does not need to be too large to meet the air outlet volume. In addition, the width of the air outlet guide 106 is relatively small, so that the distance that the airflow flowing out of the air outlet 102 flows along the air outlet guide 106 is relatively small, which can avoid the air outlet guide 106 from being too wide, and the direction of the airflow flowing downward along the air outlet guide 106 being too small with the vertical direction, which affects the air outlet range.

[0078] Optionally, the housing assembly for the air conditioner further includes an air outlet drive mechanism, which is drivingly connected to the air outlet guide plate 106 and is used to drive the air outlet guide plate 106 to move between the first air guide position and the second air guide position. The air outlet guide plate 106 can move automatically to improve the user experience. It should be noted that the air outlet guide plate 106 can also be manually pushed so that the air outlet guide plate 106 can move between the first air guide position, the closed position, and the second air guide position.

[0079] Alternatively, if Figure 7As shown, the air outlet drive mechanism includes a third motor 701, a gear 702 and a second rack 703, the gear 702 is drivingly connected to the output shaft of the third motor 701; the second rack 703 is meshed with the gear 702, and the second rack 703 is rotatably connected to the air outlet guide plate 106, and the third motor 701 drives the gear 702 and the second rack 703 to move, so that the second rack 703 drives the air outlet guide plate 106 to move between the first air guide position and the second air guide position.

[0080] In this way, the third motor 701 drives the gear 702 to rotate, and the gear 702 drives the second rack 703 to move. The second rack 703 is rotatably connected to the air outlet guide plate 106. When the second rack 703 moves, the second rack 703 can drive the air outlet guide plate 106 to rotate, thereby enabling the air guide plate to switch between the first air guide position and the second air guide position.

[0081] Optionally, the air outlet driving mechanism further includes a rotating rod 704 , one end of the rotating rod 704 is rotatably connected to one end of the air outlet guide plate 106 , and the other end of the rotating rod 704 is rotatably connected to the second rack 703 .

[0082] In the embodiment of the present disclosure, the second rack 703 extends in the vertical direction, and the second rack 703 is connected to the air outlet guide plate 106 through the rotating rod 704. One end of the rotating rod 704 is rotatably connected to the side of the second rack 703 away from the gear 702, and the other end of the rotating rod 704 is connected to the middle of the air outlet guide plate 106. In this way, when the second rack 703 moves upward, one end of the rotating rod 704 moves upward, and the rotating rod 704 rotates counterclockwise, so that the other end of the rotating rod 704 moves downward, thereby driving the air outlet guide plate 106 to rotate counterclockwise, so that the air outlet guide plate 106 moves toward the second air guide position. When the second rack 703 moves downward, one end of the rotating rod 704 moves downward, and the rotating rod 704 rotates clockwise, and the other end of the rotating rod 704 moves upward, so that the air outlet guide plate 106 rotates clockwise, thereby causing the air outlet guide plate 106 to move toward the first air guide position.

[0083] Optionally, the number of the gears 702 is one or more. When the number of the gears 702 is multiple, the multiple gears 702 include a driving gear 702 and a driven gear 4054. The driving gear 702 is connected to the output shaft of the third motor 701, the driven gear 4054 is meshed with the driving gear 702, and the driven gear 4054 is meshed with the second rack 703. In this way, the number of gears 702 can be set according to the positions of the third motor 701 and the air outlet guide plate 106, thereby improving the flexibility and convenience of the installation position of the air outlet drive mechanism.

[0084] Optionally, the second rack 703 is located at at least one end of the air outlet guide plate 106 in the length direction, and the second rack 703 extends in the height direction of the air outlet 102. The other end of the rotating rod 704 is connected to the end of the air outlet guide plate 106 in the length direction. In this way, the third motor 701, the gear 702 and the rotating rod 704 can all be arranged at one end of the air outlet guide plate 106, and it is also convenient to connect the rotating rod 704 with the end of the air outlet guide plate 106, so as to realize the driving effect of the rotating rod 704 on the air outlet guide plate 106.

[0085] Optionally, when there are multiple air outlet guide plates 106, the multiple air outlet guide plates 106 are all rotatably connected to the second rack 703. In this way, the synchronous movement of the multiple air outlet guide plates 106 can be achieved through one second rack 703, so as to improve the movement efficiency of the air outlet guide plates 106.

[0086] Optionally, the length direction of the air outlet guide plate 106 extends along the length direction of the air outlet 102, so that the air outlet guide plate 106 can improve the guiding effect of the air outlet guide plate 106 on the airflow of the air outlet 102. Preferably, the length of the air outlet guide plate 106 matches the length of the air outlet 102, so that an air outlet 102 only needs to be provided with one air outlet guide plate 106 in the length direction, and there is no need to install multiple air outlet guide plates 106.

[0087] Optionally, there are multiple air outlet drive mechanisms, and two of the multiple air outlet drive mechanisms are located at two ends of the air outlet guide plate 106 in the length direction to improve the movement stability of the air outlet guide plate 106 .

[0088] Optionally, the inner wall surface of the air outlet guide plate 106 is a plane, and the inner wall surface is connected to the outer wall surface 1061, so that when the air outlet guide plate 106 moves to the first air guiding position or the second air guiding position, adjacent air outlet guide plates 106 form an air outlet channel, one side of the air outlet channel is an arc-shaped surface, and the other side of the air outlet channel is a plane, so that the airflow in the air outlet channel can move along the arc-shaped surface to increase the air supply distance.

[0089] Optionally, when the air outlet guide plate 106 rotates to the closed position, adjacent air outlet guide plates 106 abut against each other to close the air outlet 102. Preferably, when the air outlet guide plate 106 rotates to the closed position, the air outlet guide plate 106 extends in the vertical direction so that the air outlet guide plate 106 can close the air outlet 102 with the maximum area.
