Description

Technical Field

[0002] With the development of air-conditioning technology, the appearance and functions of wall-mounted air-conditioning indoor units are constantly updated, and various new technologies emerge in an endless stream.

[0003] However, there are very few innovative air guide structures for wall-mounted air conditioner indoor units. Existing solutions typically incorporate an air guide plate and a set of swinging blades at the air outlet. The plate adjusts the vertical angle of the air outlet, while the swinging blades provide left-right airflow. Existing wall-mounted air conditioner indoor units widely utilize this air guide structure, resulting in a consistent user experience and appearance, making it difficult to elevate the product's quality.

[0004] Therefore, how to achieve innovation in air-guiding structure has become a technical problem that needs to be solved urgently in the air-conditioning industry. Summary of the Invention

[0016] Optionally, when the first rotating shaft is in the first mounting hole, the two are attracted to each other by magnetic force; and when the second rotating shaft is in the second mounting hole, the two are attracted to each other by magnetic force.

[0017] Optionally, magnets are provided on the first rotating shaft and the second rotating shaft; and

[0018] Arc-shaped magnets are embedded in the inner walls of the first mounting hole and the second mounting hole.

[0019] Optionally, the driving device includes:

[0020] at least one first gear and at least one second gear, wherein central axes thereof are adjacent to the first side and the second side of the air deflector, respectively;

[0021] The rack and the driving gear form a rack and pinion mechanism;

[0022] A motor, for driving the driving gear to rotate, wherein the driving device is configured as follows;

[0023] When the air deflector is in the closed state, the motor is rotated forward to engage the rack with the first gear, thereby causing the air deflector to rotate toward the first open state; or the motor is rotated backward to engage the rack with the second gear, thereby causing the air deflector to rotate toward the second open state.

[0024] Optionally, the driving device includes:

[0025] at least one first gear mounted on a first side of the air deflector;

[0026] at least one second gear mounted on a second side of the air deflector;

[0027] An arc-shaped rack and a motor for driving the same to rotate; the driving device is configured as follows;

[0028] When the air deflector is in the closed state, the motor is rotated forward to engage the arc-shaped rack with the first gear, thereby causing the air deflector to rotate toward the first open state; or the motor is reversed to engage the arc-shaped rack with the second gear, thereby causing the air deflector to rotate toward the second open state.

[0029] Optionally, each of the first gears is fixed to one of the first rotating shafts; and

[0030] Each of the second gears is fixed on one of the second rotating shafts.

[0031] Optionally, the first side and the second side of the air deflector are two sides in the width direction thereof;

[0032] Each of the first rotating shafts and each of the second rotating shafts extends outward from an end portion in the length direction of the air guide plate and is parallel to the length direction of the air guide plate; and

[0033] There is a gap between the first gear and the end surface of the air guide plate, and the shaft section of the first rotating shaft located at the gap is matched with the first mounting hole;

[0034] There is a gap between the second gear and the end surface of the air guide plate, and the shaft section of the second rotating shaft located at the gap is matched with the second mounting hole.

[0035] Optionally, the number of the first rotating shafts is two, and they extend outward from both ends of the length direction of the air deflector respectively; the number of the second rotating shafts is two, and they extend outward from both ends of the length direction of the air deflector respectively; and

[0036] There are two first gears and two second gears.

[0037] Optionally, the air outlet is open toward the front and bottom; and

[0038] When the air guide plate is in the closed state, its first side and second side are respectively adjacent to the upper side and lower side of the air outlet, so as to guide the wind downward when the air guide plate is in the first open state and guide the wind forward when the air guide plate is in the second open state.

[0039] In the wall-mounted air-conditioning indoor unit of the present invention, the air guide plate can rotate around its first side and can also rotate around its second side so as to be able to flip from a closed state to a first open state or a second open state, and is used to guide air in two directions. For example, if the air outlet is open to the front and bottom, the first and second sides of the air guide plate are adjacent to the upper and lower sides of the air outlet respectively. When the air guide plate is opened around its first side (upper side), it is placed vertically in front of the air outlet to guide air downward, which can meet the air supply needs of the heating mode; when the air guide plate is opened around its second side (lower side), it is placed flat in front of the lower end of the air outlet to guide air forward, which can meet the air supply needs of the cooling mode. The air guide plate of the present invention can rotate with a changeable axis, and its movement method is novel and ingenious, which improves the product's differentiation and the user's experience.

[0040] Furthermore, in the wall-mounted air-conditioning indoor unit of the present invention, the air guide plate has a first rotating shaft and a second rotating shaft, and a first mounting hole and a second mounting hole are opened on opposite sides of the air outlet (on the shell), and each hole is a half hole with a notch in the hole wall, so that the first rotating shaft and the second rotating shaft can be flexibly embedded in / detached from the first mounting hole and the second mounting hole to facilitate the switching of the rotating shafts. During the rotation of the air guide plate from the closed state to the first open state, the second rotating shaft detaches from the second mounting hole, and the first rotating shaft rotates in the first mounting hole. Similarly, during the rotation of the air guide plate from the closed state to the second open state, each first rotating shaft detaches from the first mounting hole, and the second rotating shaft rotates in the second mounting hole.

[0041] Furthermore, in the wall-mounted air conditioner indoor unit of the present invention, a rack-and-pinion mechanism is utilized to drive the movement of the rack. When the motor rotates forward, the rack moves in a first direction to engage with the first gear, while simultaneously disengaging from the second gear, thereby rotating the air deflector toward the first open state. Similarly, when the motor rotates reversely, the rack moves in a second direction to engage with the second gear, while simultaneously disengaging from the first gear, thereby rotating the air deflector toward the second open state. The present invention utilizes a simple rack-and-pinion mechanism to achieve both the switching of the air deflector's rotating shaft and the rotation of the air deflector about each rotating shaft, resulting in a highly ingenious structure.

A person of ordinary skill in the art should be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] The present invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is an indoor unit of a split wall-mounted air conditioner or a central air conditioner, and is used to regulate indoor air, such as cooling / heating, dehumidifying, introducing fresh air, etc.

[0058] like Figures 1 to 10 As shown, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a housing 10 , an air guide plate 50 and a driving device 60 .

[0059] The housing 10 defines a receiving space in which other components of the wall-mounted air conditioner indoor unit are arranged and a conditioned air flow, such as cold air or hot air, is produced. The housing 10 is provided with an air outlet 12 for delivering the conditioned air flow to the indoor environment. Figure 1 The shell 10 may be in the shape of a long strip with its length in the horizontal direction. Figure 1 The x direction is marked in the figure.

[0060] The air guide plate 50 is provided at the air outlet 12 and its function is to guide the direction of the air flow. Figure 1 and Figure 2 As shown, the air outlet 12 and the air guide plate 50 can both be long strips with their length directions parallel to the length direction of the shell 10. The air guide plate 50 guides the pitch angle of the air flow out of the air outlet 12, that is, adjusts the angle between the air outlet direction and the horizontal plane.

[0061] The driving device 60 is used to drive the air deflector 50 to move so that the air deflector 50 switches between various states. Specifically, the air deflector 50 can be in a closed state to block the air outlet 12, such as Figure 4 Of course, the air deflector 50 being closed does not necessarily mean that the air outlet 12 is completely closed. Even in some cases, if the air deflector 50 is significantly smaller than the air outlet cross-section of the air outlet 12 and cannot completely block the air outlet 12, it is still considered to be in the closed state when its large surface is perpendicular or approximately perpendicular to the air outlet direction. When the wall-mounted air conditioner indoor unit is turned off, the air deflector 50 is in the closed state.

[0062] Alternatively, based on the closed state, the driving device 60 can cause the air guide plate 50 to rotate around its first side C1 to the first open state, such as Figure 5 At this time, the air guide plate 50 can guide the outlet direction of the air flow from the air outlet 12. Of course, if the air guide plate 50 rotates in the opposite direction around its first side C1, it can return to the closed state.

[0063] Alternatively, on the basis of the closed state, the air guide plate 50 can be rotated around its second side C2 opposite to the first side C1 to a second open state, such as Figure 8 At this time, the air guide plate 50 can guide the outlet direction of the airflow from the air outlet 12. Obviously, the air guide angle of the air guide plate 50 is different in the second open state and the second open state. Of course, if the air guide plate 50 is rotated in the opposite direction around its second edge C2, it can return to the closed state.

[0064] In the wall-mounted air conditioner indoor unit of the embodiment of the present invention, the air deflector 50 can rotate both about its first side C1 and about its second side C2. That is, the air deflector 50 can switch its rotation axis so that it can flip from a closed state to a first open state or a second open state, directing air in two directions. This novel and ingenious movement of the air deflector 50 enhances product differentiation and the user experience.

[0065] For example Figure 4 、 Figure 5 and Figure 8As shown, the air outlet 12 can be opened toward the front and downward, and when the air guide plate 50 is in the closed state, its first side C1 and second side C2 are adjacent to the upper side and lower side of the air outlet 12 respectively, so as to guide the wind downward when the air guide plate 50 is in the first open state, and guide the wind forward when it is in the second open state. The first open state and the second open state referred to in the embodiment of the present invention are not limited to two specific angles. Starting from the time when the air guide plate 50 rotates around its first side C1 to open until it can no longer rotate, any angle between the two is the first open state. Similarly, starting from the time when the air guide plate 50 rotates around its second side C2 to open until it can no longer rotate, any angle between the two is the second open state. Preferably, when the air guide plate 50 is in the first open state, it is placed vertically (extending in the up and down directions) in front of the air outlet 12 for guiding the wind downward, so as to meet the need for downward air supply in the air conditioning heating mode, such as Figure 5 Similarly, when the air guide plate 50 is in the second open state, it is placed horizontally (extending in the front-to-back direction) in front of the lower end of the air outlet 12 to guide the air forward to meet the needs of the cooling mode. Figure 8 .

[0066] In some embodiments, as Figures 3 to 10 As shown, at least one first mounting hole 71 and at least one second mounting hole 72 can be respectively provided on two opposing edges of the air outlet 12. Specifically, the mounting holes (first mounting hole 71 and second mounting hole 72) can be provided on the housing 10 or on another component independent of the housing 10, which is removably mounted on the housing 10. The first mounting hole 71 and the second mounting hole 72 are both half holes with a notch in the hole wall, that is, the hole wall forms a "C" shape.

[0067] The air guide plate 50 has at least one first rotation axis 51 and at least one second rotation axis 52 , and the central axes are adjacent to the first side C1 and the second side C2 of the air guide plate 50 , respectively.

[0068] When the air guide plate 50 is in the closed state, each first rotating shaft 51 is located in a first mounting hole 71, and each second rotating shaft 52 is located in a second mounting hole 72. Figure 4 During the rotation of the air guide plate 50 from the closed state to the first open state, the second rotating shaft 52 is disengaged from the second mounting hole 72. Figure 6 , the first rotating shaft 51 rotates in the first mounting hole 71, as shown Figure 7 On the basis of the first open state, the air guide plate 50 rotates in the opposite direction around the first rotating shaft 51 and can return to the closed state. During the rotation of the air guide plate 50 from the closed state to the second open state, each first rotating shaft 51 is separated from the first mounting hole 71. Figure 9 , the second rotating shaft 52 rotates in the second mounting hole 72, as shown Figure 10On the basis of the second open state, the air guide plate 50 rotates in the opposite direction around the second rotation axis 52 and can return to the closed state.

[0069] In the embodiment of the present invention, the hole wall of the mounting hole is formed into a half hole, so that the rotating shaft (first rotating shaft 51, second rotating shaft 52) can be flexibly embedded in / out of the mounting hole, thereby facilitating the switching of the rotating shaft and realizing the axis-changing rotation of the air guide plate 50. The concept is novel and unique.

[0070] In some embodiments, since the first mounting hole 71 and the second mounting hole 72 are both half holes, when the first rotating shaft 51 or the second rotating shaft 52 is in the mounting hole, especially when Figures 1 to 10 In the embodiment shown, where the air outlet 12 opens forward and downward, to prevent the first rotating shaft 51 or the second rotating shaft 52 from unintentionally falling off, the first rotating shaft 51 is magnetically attracted to the second rotating shaft 52 when the first rotating shaft 51 is within the first mounting hole 71, and the second rotating shaft 52 is magnetically attracted to the first rotating shaft 51 when the second rotating shaft 52 is within the second mounting hole 72. Of course, during the rotation of the air deflector 50 toward the first or second open state, the force applied by the drive device 60 to the air deflector 50 can overcome the magnetic force and cause the rotating shafts to disengage from the mounting holes.

[0071] Preferably Figure 7 and Figure 10 As shown, magnets (not shown) can be provided on the first rotating shaft 51 and the second rotating shaft 52, and can be embedded in or wrapped around the first rotating shaft 51 and the second rotating shaft 52. Arc-shaped magnets 80 are embedded in the inner walls of the first mounting hole 71 and the second mounting hole 72.

[0072] In some embodiments, as Figures 3 to 10 As shown, the driving device 60 includes at least one first gear 61, at least one second gear 62, a rack 63, a driving gear 65 and a motor 64. The central axes of the first gear 61 and the second gear 62 are respectively adjacent to the first side C1 and the second side C2 of the air deflector 50. The rack 63 and the driving gear 65 constitute a gear rack mechanism. The motor 64 drives the driving gear 65 to rotate, and the driving gear 65 engages with the rack 63 to cause the rack 63 to translate. The driving device 60 is configured to; when the air deflector 50 is in the closed state, the motor 64 is rotated forward to cause the rack 63 to engage with the first gear 61, and not to engage with the second gear 62, so as to cause the air deflector 50 to rotate toward the first open state, by Figure 4 Status to Figure 5 or the motor 64 is reversed so that the rack 63 engages with the second gear 62, and does not engage with the first gear 61, so as to cause the deflector 50 to rotate toward the second open state, by Figure 4 Status to Figure 8state. It will be appreciated that when the air deflector 50 is in the first open state or the second open state, the motor 64 rotates in the corresponding reverse direction to return to the closed state. This embodiment of the present invention utilizes a simple rack-and-pinion mechanism to achieve both switching of the air deflector 50's rotating axis and rotation of the air deflector 50 about each axis, resulting in a highly ingenious structure.

[0073] like Figures 3 to 10 As shown, if the air outlet 12 faces the front and bottom, when the air guide plate 50 is in the closed state, the rack 63 is located on the side of the first gear 61 and the second gear 62 away from the air outlet 12, so that when the air guide plate 50 is in the first open state, the rack 63 supports the first gear 61, providing a rearward and upward support force to the air guide plate 50, so that the first rotating shaft 51 is closely attached to the hole wall of the first mounting hole 71, so that the air guide plate 50 is firmly maintained in the first open state, as shown in FIG. Figure 6 and Figure 7 Similarly, if Figure 9 and Figure 10 As shown, when the air deflector 50 is in the second open state, the rack 63 is used to support the second gear 62, so that the second rotating shaft 52 is closely attached to the hole wall of the second mounting hole 72 backward, so that the air deflector 50 is firmly maintained in the second open state.

[0074] In some embodiments, as Figure 2 and Figure 3 As shown, each first gear 61 can be fixed to a first rotating shaft 51, and each second gear 62 can be fixed to a second rotating shaft 52. Of course, the first gear 61 is coaxial with the first rotating shaft 51, and the second gear 62 is coaxial with the second rotating shaft 52.

[0075] In some embodiments, as Figure 2 and Figure 3 As shown, the first side C1 and the second side C2 of the air deflector 50 can be two sides in the width direction. In other words, the first side C1 and the second side C2 are the two long sides of the elongated air deflector 50. Each first rotating shaft 51 and each second rotating shaft 52 extend outward from the end portions B1 and B2 in the longitudinal direction of the air deflector 50 and are parallel to the longitudinal direction (x direction) of the air deflector 50.

[0076] Further, if Figure 3 As shown, the first gear 61 can be spaced apart from the end surface of the air deflector 50, and the shaft section of the first rotating shaft 51 located at this space engages with the first mounting hole 71. The second gear 62 can be spaced apart from the end surface of the air deflector 50, and the shaft section of the second rotating shaft 52 located at this space engages with the second mounting hole 72. In this way, the first gear 61 and the second gear 62 are used to constrain the freedom of movement of the air deflector 50 in its longitudinal direction.

[0077] like Figure 2 and Figure 3 As shown, the number of first rotating shafts 51 can be two, extending outward from both ends of the length direction of the air deflector 50, and the number of second rotating shafts 52 can be two, extending outward from both ends of the length direction of the air deflector 50. The number of first gears 61, second gears 62, and rack-and-pinion mechanisms can all be two, that is, each first rotating shaft 51 is mounted with a first gear 61, and each second rotating shaft 52 is mounted with a second gear 62. This allows both ends of the length direction of the air deflector 50 to be driven, making the force more uniform and avoiding distortion. If two rack-and-pinion mechanisms are provided, the number of motors 64 can be two to drive them, with each motor 64 driving one rack-and-pinion mechanism. Alternatively, the two driving gears 65 of the two rack-and-pinion mechanisms can be connected by a connecting shaft so that one motor 64 can drive the two driving gears 65 to rotate.

[0078] In other embodiments, the drive device 60 may include at least one first gear 61, at least one second gear 62, an arcuate rack (not shown), and a motor for driving the rotation thereof. The arcuate rack can rotate about its arcuate central axis. The first gear 61 is mounted on the first side C1 of the air deflector 50, and the second gear 62 is mounted on the second side C2 of the air deflector 50. When the air deflector 50 is in the closed state, the motor is rotated forward to engage the arcuate rack with the first gear 61, thereby causing the air deflector 50 to rotate toward the first open state; or the motor is rotated backward to engage the arcuate rack with the second gear 62, thereby causing the air deflector 50 to rotate toward the second open state.

[0079] In some embodiments, as Figure 2 As shown, a heat exchanger and a fan may be provided in the housing 10. An air inlet may be provided at the top of the housing 10. The heat exchanger, the throttling device, and the compressor, the condenser, and other refrigeration components provided in the outdoor unit of the air conditioner are connected through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan, the indoor air enters the interior of the housing 10 through the air inlet, and after completing forced convection heat exchange with the heat exchanger, heat exchange wind is formed and enters the air duct, and then blown into the room through the air outlet of the housing 10 to regulate the indoor air. The fan is preferably a cross-flow fan with an axis parallel to the longitudinal direction of the housing 10, which is provided at the inlet of the air duct. The heat exchanger may be a three-stage heat exchanger.

[0080] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
