Description

Technical Field

[0001] This application relates to the field of air conditioning technology, such as an air conditioner, and more particularly to a door structure for an air conditioner outlet. Background Technology

[0002] When an air conditioner is not in use, dust and other impurities in the air can easily enter the unit through the air outlet and duct, polluting the internal environment. Dirt inside the air conditioner is difficult to clean and can, in severe cases, affect its normal operation.

[0003] Currently, most air conditioners have an integrated door at the air outlet. This door serves as both the opening and closing mechanism for the air outlet and an integral part of the air conditioner's appearance. When closed, the door covers the air outlet, preventing dust and other impurities from entering the air duct. When the air conditioner is needed, the door opens to allow airflow.

[0004] The existing technology has at least the following problems: the door body, as an appearance component, needs to be designed to match the appearance of the air conditioner's casing, which results in high costs. Summary of the Invention

[0005] 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.

[0006] This disclosure provides an air conditioner to address the issue of high cost of the air conditioner door as an exterior component.

[0007] In some embodiments, the air conditioner includes a housing with an air outlet and an air duct inside the housing, and further includes: an air outlet grille disposed at the air outlet; an air outlet disposed in the air duct and located inside the air outlet grille; and a sliding door assembly disposed at the air outlet, including a door body capable of opening and closing the air outlet.

[0008] The air conditioner provided in this embodiment can achieve the following technical effects: the air conditioner has an air outlet grille at the air outlet so that the airflow outlet of the air duct is located inside the air outlet grille, and a sliding door assembly is provided at the airflow outlet. The sliding door assembly is used to open and close the airflow outlet, preventing external dust and other impurities from entering the air duct through the air inlet; in addition, the sliding door assembly is located inside the air outlet grille, so it does not need to match the appearance of the air conditioner housing, which can save costs.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0028] Combination Figure 1-5As shown, this embodiment of the present disclosure provides an air conditioner, including a housing 10 with an air outlet 11, an air duct 20 inside the housing 10, and the air conditioner further including an air outlet grille 30, an air outlet 21, and a sliding door assembly; wherein, the air outlet grille 30 is disposed at the air outlet 11; the air outlet 21 is disposed at the air duct 20 and is located inside the air outlet grille 30; the sliding door assembly is disposed at the air outlet 21 and includes a door body 41 that can open and close the air outlet 21.

[0029] The air conditioner has an air outlet grille 30 at the air outlet 11, so that the air outlet 21 of the air duct 20 is located inside the air outlet grille 30. A sliding door assembly is provided at the air outlet 21 to open and close the air outlet 21, preventing external dust and other impurities from entering the air duct 20 through the air inlet. Furthermore, since the sliding door assembly is located inside the air outlet grille 30, it does not need to match the appearance of the air conditioner housing 10, which can save costs.

[0030] The air conditioner casing 10 is provided with an air outlet 11, through which the air conditioner supplies air to the outside. The air outlet 11 can extend longitudinally or laterally. If the air conditioner is a floor-standing unit, the air outlet 11 can extend longitudinally, facilitating air supply at different heights. If the air conditioner is a wall-mounted unit, the air outlet 11 extends laterally, facilitating a wider air supply range. Optionally, the air outlet 11 can be rectangular. A rectangular air outlet 11 can meet the air supply requirements of the air conditioner.

[0031] An air outlet grille 30 is positioned at the air outlet 11. When airflow reaches the air outlet 11, it passes through the air outlet grille 30 and flows to the outside of the air conditioner. The air outlet grille 30 partially blocks the view, preventing users from directly seeing the interior of the air conditioner from the air outlet 11, thus affecting the air conditioner's aesthetics. The air outlet grille 30 can be displayed as part of the air conditioner's appearance. Optionally, the air outlet grille 30 includes a frame and multiple spaced-apart blades disposed within the frame, with the frame connected to the housing 10. This allows for the fixation of the air outlet grille 30 and provides some degree of visual obstruction for the user using the spaced-apart blades. When the air conditioner is off, the air outlet grille 30 also effectively blocks dust and other impurities from the outside of the air conditioner. Optionally, the upper and / or lower parts of the air outlet grille 30 are fixedly connected to the inner wall of the housing 10. This allows the air outlet grille 30 to be fixed at the air outlet 11 of the housing 10.

[0032] The air conditioner casing 10 has an air duct 20 inside. Airflow enters the casing 10 from the outside and flows along the air duct 20, thus facilitating airflow transport within the air conditioner. Optionally, a fan is installed within the air duct 20. The fan's rotation draws outside air into the casing 10, which is then transported through the air duct 20 to the air outlet 11, from which it exits the air conditioner. Optionally, the fan is a cross-flow fan. When the impeller of the cross-flow fan rotates, airflow enters the blade grid from the open end of the impeller, passes through the impeller's interior, and exits into the volute from the other side of the blade grid, forming the working airflow. The cross-flow fan within the air duct 20 can achieve a relatively large air delivery range. Optionally, the cross-flow fan is positioned within the air duct 20, with both the air duct 20 and the cross-flow fan extending longitudinally. This ensures that the airflow field created by the cross-flow fan matches the air duct 20, facilitating airflow along the air duct 20.

[0033] Air outlet 21 is located in air duct 20. Airflow flows along air duct 20 to air outlet 21 and then flows out of air duct 20. Air outlet 21 is located inside air outlet grille 30. After airflow exits from air outlet 21, airflow flows towards air outlet grille 30 and then out of air conditioner.

[0034] A sliding door assembly is located at the air outlet 21. The sliding door assembly allows the air outlet 21 to open and close by sliding the door body 41. When the air conditioner is running, the door body 41 slides to the side of the air outlet 21, opening the air outlet 21 and allowing airflow. When the air conditioner is off, the door body 41 slides to cover the air outlet 21, closing the air outlet 21 and preventing external impurities from entering the air conditioner. The sliding door assembly is located at the air outlet 21, which is inside the air outlet grille 30. This allows the sliding door assembly to be hidden inside the air outlet grille 30, making it less visible to the user. Therefore, the sliding door assembly located inside the air outlet grille 30 does not need to be considered an external component of the air conditioner and does not require matching design with the housing 10. Its shape and material can be designed in an economical manner, saving on the cost of the air conditioner.

[0035] Combination Figure 4 As shown, in some embodiments, the sliding door assembly further includes a first guide portion 42, which is disposed on the outer periphery of the airflow outlet 21; wherein, the door body 41 is provided with a second guide portion 43, which cooperates with the first guide portion 42 to open and close the airflow outlet 21.

[0036] A first guide portion 42 is provided on the outer periphery of the airflow outlet 21, and a second guide portion 43 of the door body 41 can cooperate with the first guide portion 42, allowing the door body 41 to open or close the airflow outlet 21 by sliding. By providing the cooperating first guide portion 42 and second guide portion 43, the opening and closing action of the door body 41 can be made smoother and more reliable. Optionally, the first guide portion 42 and the second guide portion 43 are slidably connected, and the second guide portion 43 can slide along the first guide portion 42. Through the sliding connection, the door body 41 slides along the first guide portion 42 to open and close. Optionally, the first guide portion 42 is provided above and / or below the airflow outlet 21, and the upper side and / or lower side of the door body 41 is the second guide portion 43. Thus, when the first guide portion 42 is positioned above the airflow outlet 21, the upper side of the door 41 can slide along the first guide portion 42 above the airflow outlet 21, making the opening and closing of the door 41 smoother. When the first guide portion 42 is positioned below the airflow outlet 21, the lower side of the door 41 can slide along the first guide portion 42 below the airflow outlet 21, making the opening and closing of the door 41 smoother. When the first guide portion 42 is positioned above and below the airflow outlet 21, the upper and lower sides of the door 41 slide along the corresponding first guide portions 42, making the opening and closing of the door 41 smoother. In addition, the first guide portion 42 located below the airflow outlet 21 can also provide some support to the door 41, making the door 41 more sturdy and stable.

[0037] Optionally, the first guide portion 42 is disposed above and below the airflow outlet 21 and extends laterally. This allows the door body 41 to move laterally along the first guide portion 42, opening or closing the airflow outlet 21 through this lateral movement. Optionally, the first guide portion 42 includes a guide groove. This allows the side of the door body 41 to extend into the guide groove and move in a fixed direction under the constraint of the guide groove. Optionally, the guide groove has an I-shaped cross-section, and the shape of the second guide portion 43 matches the guide groove. This allows the second guide portion 43 to be confined within the guide groove and to move only along the guide groove.

[0038] Optionally, the depth of the guide groove above the air outlet 21 is greater than the depth of the guide groove below the air outlet 21. This allows the door to be installed by first inserting the lower second guide portion 43 of the door 41 into the guide groove below the air outlet 21, and then inserting the upper second guide portion 43 of the door 41 into the guide groove above the air outlet 21. This eliminates the need to deform the door 41 through force, facilitating installation. It also makes the door 41 more stable and secure during movement. Since the lower second guide portion 43 of the door 41 can be stably positioned in the guide groove below the air outlet 21 due to gravity, designing a deeper guide groove above the air outlet 21 further enhances the stability of the upper second guide portion 43 within the guide groove, thereby improving the stability of the door 41 within the first guide portion 42.

[0039] Optionally, the first guide portion 42 is disposed on the left and / or right side of the airflow outlet 21, and the left and right sides of the door body 41 are second guide portions 43. In this way, the left and / or right sides of the door body 41 can slide along the corresponding first guide portion 42 to open or close. Optionally, the first guide portion 42 is disposed on the left and right sides of the airflow outlet 21 and extends longitudinally. In this way, the door body 41 can move longitudinally along the first guide portion 42, opening or closing the airflow outlet 21 by longitudinal movement.

[0040] In some embodiments, the first guide portion 42 is connected to the inner wall of the housing 10 surrounding the air outlet 11, or to the inner side of the frame of the air outlet grille 30. The inner wall of the housing 10 refers to the side of the housing 10 facing the interior of the air conditioner, and the inner side of the frame of the air outlet grille 30 refers to the side of the frame of the air outlet grille 30 facing the interior of the air conditioner. The first guide portion 42 is disposed on the outer periphery of the air outlet 21 and is connected to the inner wall of the housing 10 surrounding the air outlet 11 or to the inner side of the frame of the air outlet grille 30, indicating that the air outlet 21 and the air outlet 11 are separated only by the first guide portion 42, that is, the distance between the air outlet 21 and the air outlet 11 is relatively short. The door body 41 of the sliding door assembly is located between the air outlet 21 and the air outlet 11. The door body 41 can open and close the air outlet 21 to prevent external dust and other impurities from entering the air outlet 21. Furthermore, even when the door 41 closes the airflow outlet 21, the door 41 can still cover the air outlet grille 30 from the inside of the housing 10, preventing external impurities from entering the space between the air duct 20 and the housing 10 from the air outlet 11.

[0041] The first guide portion 42 can be connected to the inner wall of the housing 10 surrounding the air outlet 11, so that the door 41 is confined between the air outlet 21 and the air outlet grille 30. The connection of the first guide portion 42 to the inner wall of the housing 10 does not affect the disassembly of the air outlet grille 30. The first guide portion 42 can also be connected to the inner side of the frame of the air outlet grille 30, which also allows the door 41 to be located between the air outlet 21 and the air outlet grille 30.

[0042] Combination Figure 2-5 As shown, in some embodiments, the air conditioner further includes a transmission assembly 50 and a drive mechanism 51. The transmission assembly 50 is disposed on the inner side of the door 41; the drive mechanism 51 is disposed inside the housing 10 and connected to the transmission assembly 50 to drive the second guide portion 43 to move along the first guide portion 42. When the drive mechanism 51 operates, it can transmit force to the door 41 through the transmission assembly 50, thereby driving the door 41 to move. The inner side of the door 41 refers to the side of the door 41 facing the air duct 20. The transmission assembly 50 is disposed on the inner side of the door 41 and interacts with the door 41 from the inside, avoiding occupying the space around the outer periphery of the door 41 and the space between the door 41 and the air outlet grille 30. The transmission assembly 50, being disposed on the inner side of the door 41, will not obstruct the airflow within the air duct 20. Because when the door 41 is opened, the door 41 moves to the outer periphery of the airflow outlet 21, and the transmission component 50 on the door 41 does not occupy the airflow passage; when the door 41 is closed, the door 41 covers the airflow outlet 21, the airflow no longer flows, and the transmission component 50 does not block the airflow.

[0043] Optionally, the drive mechanism 51 is disposed on the outer wall of the air duct 20. Disposing of the drive mechanism 51 on the outer wall of the air duct 20 serves two purposes: it secures the drive mechanism 51 and it avoids occupying space within the air duct 20. Furthermore, the air outlet 21 of the air duct 20 is equipped with a sliding door assembly, and the inner side of the door body 41 of the sliding door assembly is provided with a transmission component 50. Disposing of the drive mechanism 51 on the outer wall of the air duct 20 minimizes the distance between the drive mechanism 51 and the transmission component 50, facilitating their interaction.

[0044] Combination Figure 6 As shown, in some embodiments, the transmission assembly 50 includes a base 501 and a rack 502. The base 501 is connected to the inner side of the door body 41; the rack 502 is disposed on the inner side of the base 501 and extends laterally or longitudinally. The inner side of the base 501 refers to the side of the base 501 facing the airflow outlet 21. The rack 502 is disposed on the inner side of the base 501 to facilitate the interaction between the drive mechanism 51 and the rack 502. The rack 502 extends laterally or longitudinally, and when the drive mechanism 51 drives the rack 502, the rack 502 can move laterally or longitudinally, thereby driving the door body 41 to move laterally or longitudinally.

[0045] Combination Figure 6 As shown, optionally, a latching assembly 70 is provided on the inner side of the door body 41, and the base 501 is latched onto the latching assembly 70. The latching assembly 70 facilitates the disassembly and installation of the transmission assembly 50. Optionally, the latching assembly 70 includes a claw 71, and the base 501 has a slot 503 for the claw 71 to engage. By compressing and deforming the claw 71, the claw 71 engages into the slot 503, thus connecting the transmission assembly 50 to the latching assembly 70. Similarly, by compressing and deforming the claw 71, the claw 71 can disengage from the slot 503, thus separating the transmission assembly 50 from the latching assembly 70. Optionally, the slots 503 are located above and below the rack 502. The claw 71 engaging into the slots 503 above and below the rack 502 provides a more secure fixation of the transmission assembly 50. When the drive mechanism 51 moves the rack 502, the pawl 71 can fix the rack 502 from above and below, so that the movement of the rack 502 can drive the door 41 to move smoothly.

[0046] Combination Figure 2-5 As shown, in some embodiments, the drive mechanism 51 includes a motor 510 and a gear 511. The motor 510 is disposed inside the housing 10 and includes a rotating shaft; the gear 511 is sleeved on the rotating shaft and meshes with a rack 502.

[0047] When the motor 510 is running, the shaft rotates, driving the gear 511 to rotate. The gear 511 meshes with the rack 502, causing the rack 502 to move. This enables the drive mechanism 51 to drive the rack 502. Optionally, the drive mechanism 51 is located on the outside of the air duct 20. This avoids the drive mechanism 51 creating air resistance within the air duct 20. Optionally, the rack 502 extends laterally, and the drive mechanism 51 is located on the left or right side of the air duct 20. The drive mechanism 51 contacts the rack 502 from the left or right side of the air duct 20, enabling it to drive the rack 502 from the outside of the air duct 20.

[0048] In some embodiments, the air conditioner further includes a gearbox 60, which is disposed inside the housing 10 and covers the outside of the gear 511. The gearbox 60 covers the outside of the gear 511, protecting the gear 511 from operation, preventing collisions with other components, and preventing impurities from falling onto the gear 511 and causing malfunctions. Optionally, the gearbox 60 is disposed on the outer wall of the air duct 20. This facilitates the placement of the gear 511 on the outside of the air duct 20, allows the gear 511 to be close to the rack 502, and avoids occupying internal space within the air duct 20.

[0049] Optionally, the motor 510 is fixed to the outer wall of the gearbox 60, and the shaft of the motor 510 extends into the gearbox 60. The gearbox 60 provides a fixing point for the motor 510, facilitating its fixation. Optionally, the motor 510 is connected to both the outer wall of the gearbox 60 and the outer wall of the air duct 20. This makes the motor 510 more robust and stable, preventing it from shaking or becoming unstable during operation.

[0050] In some embodiments, the outer wall of the gearbox 60 is provided with a guide rail 61, and the side of the base 501 extends into the guide rail 61 so that when the gear 511 drives the rack 502, the base 501 moves along the guide rail 61. The base 501 is provided with a rack 502. The rotation of the gear 511 drives the rack 502 to move, and the rack 502 drives the base 501 to move. The side of the base 501 extends into the guide rail 61, so that it can move under the restriction of the guide rail 61, and avoid the gear 511 pushing the rack 502 towards the air outlet 11 side, which would affect the opening and closing action of the door 41.

[0051] Optionally, the gearbox 60 has guide rails 61 extending laterally on both the upper and lower parts of the side facing the rack 502. The upper side of the base 501 extends into the upper guide rail 61, and the lower side extends into the lower guide rail 61. Thus, when the gear 511 drives the rack 502 to move, the rack 502 drives the base 501 to move. The upper side of the base 501 moves along the upper guide rail 61, and the lower side moves along the lower guide rail 61, making the movement of the base 501 smoother. Furthermore, when the gear 511 drives the rack 502 to move, the guide rails 61 limit the movement of the base 501, preventing the rack 502, base 501, and door 41 from being pushed towards the air outlet 11 of the air conditioner by the gear 511, which could cause deformation of the door 41 or make the opening and closing of the door 41 less smooth.

[0052] Optionally, the side of the gearbox 60 facing the rack 502 is open. This allows the gear 511 to protrude from the gearbox 60, thereby enabling the gear 511 to mesh with the rack 502 outside the gearbox 60.

[0053] Combination Figure 4 , 7As shown, in some embodiments, the door 41 includes a first door 411 and a second door 412 arranged side by side. The second guide portion 43 of both the first door 411 and the second door 412 can move along the first guide portion 42. Both the first door 411 and the second door 412 can move relative to the first guide portion 42, allowing the airflow outlet 21 to open and close via the movement of the first door 411 and the second door 412. Optionally, the first door 411 and the second door 412 slide laterally along the first guide portion 42. When opening the airflow outlet 21, the first door 411 moves laterally towards one side of the airflow outlet 21, and the second door 412 moves laterally towards the other side of the airflow outlet 21. The opening of the airflow outlet 21 is achieved through the opposite movement of the first and second door 412. When closing, the first door 411 and the second door 412 move closer to each other until the airflow outlet 21 is closed.

[0054] Combination Figure 4 As shown, optionally, there are two drive mechanisms 51. One drive mechanism 51 drives the first door 411 to move along the first guide portion 42, and the other drive mechanism 51 drives the second door 412 to move along the first guide portion 42. With two drive mechanisms 51, the first door 411 and the second door 412 can be moved respectively, facilitating the opening and closing of the airflow outlet 21. Optionally, one drive mechanism 51 is located on the left outer wall of the air duct 20, and the other drive mechanism 51 is located on the right outer wall of the air duct 20. This allows for a reasonable arrangement of the drive mechanisms 51, facilitating their operation of the first door 411 and the second door 412.

[0055] By setting up a first door 411 and a second door 412, and making the first door 411 and the second door 412 open and close the airflow outlet 21 in a sliding manner, the movement path of the first door 411 and the second door 412 can be shortened, making it easier for the drive mechanism 51 to drive the first door 411 and the second door 412 to move in a smaller space.

[0056] Combination Figure 7 As shown, in some embodiments, the first door body 411 has a notch on the side corresponding to the second door body 412, the notch extends along the length direction of the first door body 411, and the second door body 412 has an extension 4120 extending into the notch on the side opposite to the notch.

[0057] The length direction of the first door body 411 refers to the direction in which the first door body 411 extends. For example, when the first door body 411 is upright, the direction in which the long side of the first door body 411 perpendicular to the ground extends is the length direction of the first door body 411. The first door body 411 and the second door body 412 are arranged side by side. The side corresponding to the first door body 411 and the second door body 412 refers to the side where the first door body 411 and the second door body 412 are connected. The first door body 411 has a notch on this side, and the second door body 412 has an extension 4120 on the side where it is connected to the first door body 411. The extension 4120 extends into the notch. This design allows the gap between the first door 411 and the second door 412 to bend when they are joined, which improves the sealing of the air duct 20 by the first door 411 and the second door 412 and prevents dust and other impurities from entering the air duct 20 through the gap at the joint of the first door 411 and the second door 412.

[0058] In some embodiments, there are two doors 41 arranged vertically. Each door 41 includes a first door 411 and a second door 412. The first guide portion 42 at the upper part of the airflow outlet 21 cooperates with the upper side of the upper door 41, and the first guide portion 42 at the lower part of the airflow outlet 21 cooperates with the lower side of the lower door 41. There are four drive mechanisms 51. The inner surfaces of the first door 411 and the second door 412 are provided with transmission components 50. The drive mechanisms 51 drive each of the first door 411 and the second door 412. In this way, the upper and lower doors 41 can open and close the airflow outlet 21, which has a larger area. Furthermore, by providing multiple drive mechanisms 51, each door 41 can be driven, so that each door 41 can be opened and closed in a controlled manner, and the opening and closing actions of each door 41 can be smooth and stable.
