Description

Technical Field

[0001] This application relates to the field of air conditioner technology, for example to a wall-mounted air conditioner. Background Technology

[0002] Currently, the airflow from air conditioner vents is quite forceful. Being directly exposed to cold or hot air from an air conditioner for extended periods can be harmful to health. Furthermore, when the airflow blows directly onto the user, the user experience is poor, affecting user comfort.

[0003] To address the discomfort caused by direct airflow from an air conditioner, a wall-mounted air conditioner indoor unit is provided, comprising: a housing with two side-by-side air outlets at the bottom facing forward and extending laterally along the wall-mounted air conditioner indoor unit; two cross-flow fans arranged coaxially inside the housing along the lateral direction of the wall-mounted air conditioner indoor unit, each cross-flow fan corresponding to one air outlet in the lateral direction of the wall-mounted air conditioner indoor unit; and two air guide plates, each air guide plate corresponding to the inner side of one air outlet, configured to rotate about an axis parallel to the lateral direction of the wall-mounted air conditioner indoor unit to adjust the vertical airflow direction of the corresponding cross-flow fan.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Existing wall-mounted air conditioners change the airflow direction by adjusting the rotation of the air guide plate. Since the air guide plate is fixed in position, its air delivery distance and range are small, which cannot meet the different needs of users for air volume, wind speed, wind feel and air delivery distance under different conditions, resulting in a poor user experience. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a wall-mounted air conditioner to solve the problem that air conditioners cannot meet users' needs for different air outlet patterns.

[0008] In some embodiments, the wall-mounted air conditioner includes: a housing having an air inlet and an air outlet; a fan housing movably disposed within the housing, defining an air outlet duct, the air outlet duct being connected to both the air inlet and the air outlet; an impeller rotatably disposed within the air outlet, used to drive outside air to flow in from the air inlet and out from the air outlet; and a drive unit disposed within the housing and drivenly connected to the fan housing, used to drive the fan housing to move relative to the air outlet.

[0009] In some embodiments, the fan housing is arranged laterally along the housing and the two ends of the fan housing are connected to the housing via a rotating shaft. The driving part includes: a first driving motor disposed inside the housing; a driving wheel connected to the driving shaft of the first driving motor; and a driven wheel disposed on the rotating shaft and meshing with the driving wheel, for driving the fan housing to swing relative to the air outlet.

[0010] In some embodiments, the wall-mounted air conditioner further includes: an air guide plate movably disposed at the air outlet for changing the airflow direction of the air outlet; and a drive assembly disposed within the housing and drivenly connected to the air guide plate for driving the air guide plate to move in a direction away from the air outlet and to rotate around the connecting shaft between the air guide plate and the drive mechanism.

[0011] In some embodiments, the driving component includes: a stepping slider driving unit disposed within the housing and connected to the air guide plate, for driving the air guide plate to open and close the air outlet.

[0012] In some embodiments, the driving assembly further includes: a second driving motor disposed in the stepper slider driving unit; and a rotating rod, one end of which is connected to the second driving motor and the other end of which is connected to the air guide plate, for driving the air guide plate to rotate around the axis of rotation of the second driving motor.

[0013] In some embodiments, the wall-mounted air conditioner further includes: a detection device disposed on the housing, for acquiring environmental parameters around the housing and the user's location; and a controller electrically connected to the detection device, the drive unit, and the drive assembly, for controlling the drive unit and the drive assembly to rotate in coordination based on the environmental parameters acquired by the detection device and / or the user's location when the air guide plate is open.

[0014] In some embodiments, the controller is configured to control the drive unit to rotate the end of the fan housing closest to the air outlet upwards, and to control the drive assembly to drive the lower end of the air guide plate to be less than the distance between the upper end of the air guide plate and the air outlet.

[0015] In some embodiments, the controller is further configured to control the drive unit to drive the end of the fan housing closest to the air outlet to rotate downwards, and to control the drive assembly to drive the lower end of the air guide plate to be less than the distance between the upper end of the air guide plate and the air outlet.

[0016] In some embodiments, there are two fan housings and two impellers, with both fan housings arranged side by side in the housing along the lateral direction of the housing, and both impellers rotatably arranged side by side in the fan housing along the lateral direction of the housing.

[0017] In some embodiments, the drive unit further includes a drive shaft disposed between the two fan housings and connected to the two fan housings. The connection ends of the drive shaft and the two fan housings are retractable, so that one or both ends of the drive shaft are connected to the fan housing on the corresponding side, thereby driving one or both of the two fan housings to move.

[0018] The wall-mounted air conditioner provided in this disclosure can achieve the following technical effects:

[0019] By installing a movable fan housing inside the casing of a wall-mounted air conditioner, the direction of airflow inside the air conditioner can be changed by controlling the movement of the fan housing. A rotatable impeller installed inside the fan housing provides power for the airflow. By setting a drive unit to control the movement of the fan housing relative to the air outlet, the position of the fan housing relative to the air outlet of the wall-mounted air conditioner can be changed, thereby changing the air outlet angle and air volume of the wall-mounted air conditioner. This can improve the user experience and meet various air supply needs of users.

[0036] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] To address the problem that existing air conditioners cannot meet users' needs for different air outlet patterns, combined with Figures 1 to 6 This disclosure provides a wall-mounted air conditioner, including: a housing 10, a fan housing 11, an impeller 12, and a drive unit 13.

[0039] The housing 10 is a closed three-dimensional structure with an internal cavity. The three-dimensional structure is roughly cubic, but unlike a cubic structure, the front wall of the housing 10 is inclined. The distance between the upper end of the front wall and the rear wall of the housing 10 is less than the distance between the lower end of the front wall and the rear wall of the housing 10. This inclined front wall design allows sufficient space for the internal components of the wall-mounted air conditioner to move.

[0040] The housing 10 has an air inlet 101 and an air outlet 102. The air inlet 101 is located on the upper wall of the housing 10; the air outlet 102 is located at the junction of the front and lower walls of the housing 10. The air outlet 102 is inclined, and the distance between the upper end of the air outlet 102 and the rear wall of the housing 10 is greater than the distance between the lower end of the air outlet 102 and the rear wall of the housing 10. In this way, by tilting the air outlet 102, the internal space of the housing can be increased.

[0041] In this way, by providing an air inlet 101 and an air outlet 102 on the housing 10, an air flow channel can be formed, allowing air to flow in from the air inlet 101 and out from the inclined air outlet 102, so that air can continuously circulate.

[0042] The fan housing 11 has a volute structure and is arranged inside the housing 10 along the transverse direction of the housing 10. The fan housing 11 has an inlet and an outlet. The inlet is arranged in the direction of the air inlet 101 of the housing 10, and the outlet is arranged in the direction of the air outlet 102. The fan housing 11 defines a volute-shaped air duct. By setting the inlet in the direction of the air inlet 101 and the outlet in the direction of the air outlet 102, the resistance of air flow in the wall-mounted air conditioner can be reduced, thus ensuring the air output effect of the wall-mounted air conditioner.

[0043] The connection between the fan housing 11 and the housing 10 can be achieved by connecting the fan housing 11 to the housing 10 at both ends via a rotating shaft that is arranged in the transverse direction of the housing 10, allowing the fan housing 11 to rotate relative to the housing 10; or by providing movable connecting sliders at both ends of the fan housing 11, which are connected to the housing 10 via sliders and slide rails, allowing the fan housing 11 to move relative to the housing 10. It is understood that the connection between the fan housing 11 and the housing 10 includes, but is not limited to, the above two forms, and the movement between the fan housing 11 and the housing 10 is also not limited to the above two forms.

[0044] The impeller 12 is disposed inside the fan housing 11 along the transverse direction of the housing 10. The impeller 12 is driven by an electric motor and connected to the fan housing 11 via a rotating shaft. The electric motor drives the impeller 12 to rotate relative to the fan housing 11. When the impeller 12 rotates, the airflow enters the impeller 12 from the open part of the impeller 12, passes through the interior of the impeller 12, and is discharged into the fan housing 11 from the other side of the impeller 12, forming a working airflow. The rotation of the impeller 12 can drive the outside air to flow into the housing 10 from the air inlet 101, flow through the fan housing 11, and then flow out of the housing 10 from the air outlet 102.

[0045] The drive unit 13 can be disposed at the top of the housing 10 or at the bottom of the housing 10. Preferably, it is disposed at the bottom of the housing 10. Figure 3 As shown in the diagram, it can be understood that the location of the drive unit 13 is not unique.

[0046] The drive unit 13 is driven to the fan housing 11, and can either drive the fan housing 11 to move relative to the air outlet 102 or drive the fan housing 11 to rotate relative to the air outlet 102. For example, Figure 3 shows one specific connection configuration where the drive unit 13 drives the fan housing 11 to rotate relative to the air outlet 102. In this way, the drive unit 13 can drive the fan housing 11 to rotate relative to the air outlet 102.

[0047] The wall-mounted air conditioner using this embodiment of the present disclosure provides power for airflow by providing a rotatable impeller 12 inside the fan housing 11. By providing a movable fan housing 11 inside the wall-mounted air conditioner housing 10, the direction of airflow inside the wall-mounted air conditioner can be changed by controlling the movement of the fan housing 11. By providing a drive unit 13 to control the movement of the fan housing 11 relative to the air outlet 102, the position of the wall-mounted air conditioner fan housing 11 relative to the air outlet 102 is changed, thereby changing the air outlet angle and air volume of the wall-mounted air conditioner, which can improve the user experience and meet the user's various air supply needs.

[0048] In some alternative embodiments, the fan housing 11 is arranged laterally along the housing 10 and the two lateral ends of the fan housing 11 are connected to the housing 10 via a rotating shaft (not shown in the figure). The drive unit 13 includes: a first drive motor 131, a drive wheel 132 and a driven wheel 133. The first drive motor 131 is located inside the housing; the drive wheel 132 is connected to the drive shaft of the first drive motor; the driven wheel 133 is located on the rotating shaft and meshes with the drive wheel 132 to drive the fan housing 11 to swing relative to the air outlet 102.

[0049] The fan housing 11 is arranged laterally along the housing, and its two lateral ends are connected to the housing 10 via a rotating shaft (not shown in the figure). The location of the first drive motor 131 is not unique. The first drive motor 131 is used to provide power for the rotation of the fan housing 11. For example, the first drive motor 131 is located at one end near the two ends of the fan housing 11 connected to the housing 10. The drive shaft of the first drive motor 131 is arranged vertically, and the first drive motor 131 is fixedly connected to the rear wall of the housing 10 by bolts and nuts.

[0050] Optionally, the driving gear 132 is a helical gear with its axis arranged vertically, and the driven gear 133 is a helical cylindrical gear with its axis arranged horizontally. The helical gear and the helical cylindrical gear mesh with each other. For example, such as... Figure 3 and Figure 4As shown in the diagram. In this way, rotational motion in the vertical direction can be converted into rotational motion in the horizontal direction. In addition, the contact line of the helical gear teeth is a straight line inclined to the gear axis, and the engagement and disengagement of the teeth are gradual, so the transmission process is smoother than that of spur gears. This can reduce noise. Furthermore, using helical gears and helical cylindrical gears for transmission can also reduce the load on each pair of teeth, thereby relatively improving the load-bearing capacity of the gears and extending their service life.

[0051] In some optional embodiments, the wall-mounted air conditioner further includes: an air guide plate 14 and a drive assembly 15, wherein the air guide plate 14 is movably disposed at the air outlet 102 for changing the airflow direction of the air outlet 102; the drive assembly 15 is disposed in the housing and drivenly connected to the air guide plate 14 for driving the air guide plate 14 to move in a direction away from the air outlet 102 and to rotate around the connecting shaft between the air guide plate 14 and the drive mechanism.

[0052] The air guide plate 14 is set at the air outlet 102 and covers the air outlet 102. It can completely seal the air outlet 102 when the wall-mounted air conditioner is not working, preventing external dust from entering the housing from the air outlet 102 and affecting the normal use of internal components.

[0053] The drive component 15 is located inside the housing 10 and is driven to connect with the air guide plate 14. It can drive the air guide plate 14 to move relative to the air outlet 102 of the housing 10, thereby changing the air outlet direction at the air outlet 102 and improving the user experience.

[0054] Optionally, the wall-mounted air conditioner also includes a heat exchanger (not shown in the figure), which is disposed between the fan housing 11 and the air guide plate 14 and connected to the housing 10, for exchanging heat with the air flowing out from the air outlet 102.

[0055] In some alternative embodiments, the drive assembly 15 includes a stepping slider drive unit 151, which is disposed inside the housing 10 and connected to the air guide plate 14 for driving the air guide plate 14 to open and close the air outlet 102.

[0056] like Figure 5 and Figure 6As shown, the stepper slider drive unit 151 includes: a support base 152, a slider 154, a connecting rod 155, a ball screw (not shown in the figure), and a stepper motor 153. The support base 152 includes: a base plate 1521 and two side plates 1522. The two side plates 1522 are mounted on both ends of the upper surface of the base plate 1521. The upper surface of the base plate 1521 and the two side plates 1522 enclose the mounting space for the slider and the ball screw. The base plate 1521 is fixedly connected to the housing. The two ends of the ball screw are connected to two side plates 1522 respectively. The screw of the ball screw passes through a slider 154, which is fixedly connected to the nut of the ball screw, allowing the slider 154 to move along the axis of the ball screw. A stepper motor 153 is located on one of the side plates 1522 opposite to the ball screw and is connected to the ball screw. It drives the ball screw to rotate, thereby causing the slider to reciprocate linearly along the axis of the ball screw. A connecting rod 155 is connected to both the slider 154 and the air guide plate 14, and drives the air guide plate 14 to reciprocate linearly along the axis of the ball screw. In this way, by controlling the movement distance of the slider 154 on the ball screw, the distance the air guide plate 14 moves relative to the air outlet 102 can be controlled, thereby controlling the air volume of the wall-mounted air conditioner, improving the air outlet effect of the wall-mounted air conditioner, and thus meeting the user's needs.

[0057] In some optional embodiments, the drive assembly 15 further includes: a second drive motor 156 and a rotating rod 157, wherein the second drive motor 156 is disposed in the stepping slider drive unit 151; one end of the rotating rod 157 is connected to the second drive motor 156 and the other end is connected to the air guide plate 14, for driving the air guide plate 14 to rotate around the axis of the rotating shaft of the second drive motor 156.

[0058] The second drive motor 156 is mounted on the connecting rod 155 and is fixedly connected to the connecting rod 155 by bolts and nuts. The rotating shaft of the second drive motor 156 is connected to one end of the rotating rod, which drives the rotating rod 157 to rotate around the axis of the rotating shaft of the second drive motor 156. The other end of the rotating rod 157 is connected to the air guide plate 14. In this way, by controlling the second drive motor 156, the rotation angle of the air guide plate 14 can be controlled, achieving precise control of the airflow from the wall-mounted air conditioner and improving the user experience.

[0059] Optionally, the air inlet grille 103 is located at the air outlet 102, covering the air outlet 102 and arranged along the lateral direction of the housing to form a lateral opening. The air inlet grille 103 can be opened and closed. When the wall-mounted air conditioner starts working, the air inlet grille 103 opens, with the blades at an angle of 45 to 60 degrees to the horizontal direction and the opening facing the front wall, to guide air from the air inlet 101 into the wall-mounted air conditioner. When the wall-mounted air conditioner stops working, the air inlet grille 103 closes to prevent dust from falling into the air conditioner from the air inlet 101 and affecting the service life of the internal components of the air conditioner.

[0060] Optionally, an air outlet grille 104 is disposed at the air outlet 102, covering the connection between the air outlet 102 and the housing, and the air outlet grille 104 is fixed at the air outlet 102. The air outlet grille 104 is a fixed straight blade type, consisting of front and rear double layers of blades, with the front layer of blades being adjustable and the rear layer of blades being fixed. Both layers of blades are vertically installed, so that the air blown out of the air outlet 102 forms a planar direct current airflow.

[0061] In this way, the vertically arranged grilles ensure a uniform distribution of the downward airflow, providing users with a more comfortable and stable airflow experience.

[0062] Optionally, the air conditioner is equipped with a blade regulating valve, which can change the airflow speed by controlling the opening of the blades, and work with the air guide plate 14 to follow the air supply in real time, providing users with a variety of air supply modes.

[0063] In some alternative embodiments, the wall-mounted air conditioner further includes: a detection device (not shown in the figure) and a controller (not shown in the figure). The detection device is located in the housing and is used to acquire environmental parameters around the housing and / or the user's position. The controller is electrically connected to the detection device, the drive unit 13 and the drive assembly 15, and is used to control the drive unit 13 and the drive assembly 15 to rotate in coordination according to the ambient temperature and the user's position acquired by the detection device when the air guide plate 14 is open.

[0064] The detection device includes a lidar, a wide-angle camera, a humidity sensor, and a temperature sensor. It detects the user's location, ambient temperature, and humidity, and transmits these information to the controller in real time. The controller receives the detection information and controls the rotation angles of the fan housing 11 and the air guide plate 14 accordingly to achieve targeted airflow and improve the intelligence of the wall-mounted air conditioner.

[0065] For example, when the controller receives the detected user location information, it can adjust the air outlet direction of the fan housing 11 and the rotation angle of the air guide plate 14 of the wall-mounted air conditioner according to the user's location change, so as to realize the function of sending air following the human body's movement trajectory.

[0066] When the controller receives ambient temperature and humidity information detected by the detection device, it can determine the most suitable wind speed, temperature, wind direction and humidity based on the data stored in the controller. The controller controls the impeller speed of the wall-mounted air conditioner, the rotation angle of the fan casing 11 and the moving distance and rotation angle of the air guide plate 14, so that the wall-mounted air conditioner reaches the most suitable wind speed and wind direction, thereby adjusting the indoor environment to reach the most suitable temperature and humidity.

[0067] In some alternative embodiments, the controller is configured to control the drive unit 13 to drive the end of the fan housing 11 closest to the air outlet 102 to rotate upward, and the control drive assembly 15 to drive the lower end of the air guide plate 14 to be less than the distance between the upper end of the air guide plate 14 and the air outlet 102.

[0068] For example, when the wall-mounted air conditioner is in cooling mode, if the user's position detected by the detection device is at the location where the airflow from the wall-mounted air conditioner is blowing out, the controller will adopt the control method of the above-mentioned optional embodiment to avoid direct cold air blowing on the user while achieving a better cooling effect. In this way, the controller can control the start and stop of the air guide plate 14 relative to the air outlet 102 by controlling the start and stop of the first drive motor 131; by controlling the forward and reverse rotation of the first drive motor 131, the rotation direction of the ball screw can be controlled, thereby controlling the movement direction and distance of the air guide plate 14. By controlling the rotation direction and speed of the first drive motor 131, the upward rotation and rotation angle of the end of the fan housing 11 closest to the air outlet 102 can be controlled, achieving precise control of the fan housing 11. By controlling the rotation direction of the second drive motor 156, the rotation direction of the air guide plate 14 can be controlled; by controlling the rotation angle of the second drive motor 156, the rotation angle of the air guide plate 14 can be controlled, thereby achieving precise control of the air guide plate 14. By controlling the coordinated rotation of the fan housing 11 and the air guide plate 14, precise control of the air output of the wall-mounted air conditioner can be achieved, thereby improving the user's air supply experience.

[0069] In some alternative embodiments, the controller is also configured to control the drive unit 13 to drive the end of the fan housing 11 closest to the air outlet 102 to rotate downward, and to control the drive assembly 15 to drive the lower end of the air guide plate 14 to be less than the distance between the upper end of the air guide plate 14 and the air outlet 102.

[0070] For example, when the wall-mounted air conditioner is in heating mode, if the user's position detected by the detection device is in the direction of the air conditioner's air outlet, the controller will adopt the control method of the above optional embodiment to avoid hot air blowing directly on the user while achieving a better heating effect.

[0071] In this way, by controlling the rotation direction and speed of the first drive motor 131, the downward rotation and rotation angle of the end of the fan housing 11 closest to the air outlet 102 can be controlled, thus achieving precise control of the fan housing 11. By controlling the rotation direction of the second drive motor 156, the rotation direction of the air guide plate 14 can be controlled; by controlling the rotation angle of the second drive motor 156, the rotation angle of the air guide plate 14 can be controlled, thereby achieving precise control of the air guide plate 14; by coordinating the rotation of the fan housing 11 and the air guide plate 14, precise control of the air outlet of the wall-mounted air conditioner is achieved, thereby improving the user's air supply experience.

[0072] In some alternative embodiments, there are two fan housings 11 and two impellers 12. The two fan housings 11 are arranged side by side in the housing 10 along the lateral direction of the housing 10, and the two impellers 12 are rotatably arranged side by side in the fan housings 11 along the lateral direction of the housing.

[0073] In this way, by setting two fan housings 11 and impellers 12, the air output of the wall-mounted air conditioner can be more precisely controlled. When it is not necessary to quickly change the indoor ambient temperature or when the required air volume is small, only one impeller 12 can be controlled to operate. By specifically changing the air output mode of the wall-mounted air conditioner, energy consumption can be effectively reduced.

[0074] In some alternative embodiments, the drive unit 13 further includes a drive shaft 134 disposed between the two fan housings 11 and connected to the two fan housings 11. The connection ends of the drive shaft 134 and the two fan housings 11 are retractable, so that one or both ends of the drive shaft 134 are connected to the fan housing 11 on the corresponding side, thereby driving one or both of the two fan housings 11 to move.

[0075] The drive shaft 134 is located between the two fan housings 11 and is arranged laterally along the fan housing 11. The drive shaft 134 is connected to the fan housing 11 and can drive the fan housing 11 to rotate relative to the housing. The connection ends of the drive shaft 134 and the two fan housings 11 can be extended or retracted.

[0076] In this way, by setting the drive shaft 134 to be telescopically connected to the two fan housings 11, the rotation of one of the two fan housings 11 can be controlled individually, or both fan housings 11 can be controlled to rotate, or neither fan housing 11 can be controlled to rotate. This enables precise control of the fan housings 11, and thus precise control of the air outlet mode of the wall-mounted air conditioner. This allows the wall-mounted air conditioner to have multiple air outlet modes, such as single fan stationary air supply, single fan oscillating air supply, dual fan stationary air supply, dual fan oscillating air supply, etc., which can meet various user needs.
