[0050] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0051] The following is for reference. Figures 1-25 This invention describes an air conditioner according to an embodiment of the present invention.

[0052] refer to Figures 1-10 The air conditioner according to an embodiment of the present utility model includes: a housing 10, a door opening and closing assembly 20, and a door opening and closing drive assembly 30.

[0053] The housing 10 has an air inlet and an air outlet 11. Airflow enters the housing 10 through the air inlet and exits through the air outlet 11. The housing 10 serves to prevent dust and protect internal components. The air inlet on the housing 10 is used to introduce indoor or outdoor air into the housing 10, and the air outlet 11 is used to exhaust treated air into the room. For example, the air inlet is located at the rear of the housing 10, and the air outlet 11 is located at the front of the housing 10. For example, there may be one air outlet 11, which may extend vertically.

[0054] The housing 10 may include a front housing component 12 and a rear housing component. The front housing component 12 may be located on the front side of the rear housing component, the air inlet may be located on the rear housing component, and the air outlet 11 may be located on the front housing component 12.

[0055] For example, an air conditioner includes a heat exchange and air supply assembly housed within the casing 10. This assembly heats or cools the air supplied to the heat exchange and air supply unit from the air inlet and discharges it from the air outlet 11. For instance, air enters the casing 10 from the air inlet, exchanges heat with the heat exchange and air supply assembly, and is then discharged into the room from the air outlet 11, thereby regulating the indoor temperature.

[0056] For example, the heat exchange and air supply assembly includes a heat exchanger component, a duct component, and an air outlet frame component 40. The heat exchanger component is located between the air inlet and the duct component, and the air outlet frame component 40 is connected to the front side of the duct component and can be installed on the front housing component 12. The duct component includes a duct casing and a fan wheel. At least a portion of the fan wheel is disposed within the duct casing, which forms a duct. The air outlet frame component 40 forms an air outlet channel 41, which is located downstream of and communicates with the duct. The air outlet side of the air outlet channel 41 is opposite to the air outlet 11. The fan wheel is used to drive the airflow, and the heat exchanger component is used to exchange heat with the airflow to regulate the airflow temperature.

[0057] The air conditioner can be a split-type air conditioner, such as a split-type floor-standing air conditioner. When the air conditioner is a split-type air conditioner, it can include an indoor unit and an outdoor unit, wherein the indoor unit includes the aforementioned casing 10, door opening and closing assembly 20, door opening and closing drive assembly 30, and heat exchange and air supply assembly.

[0058] The door opening / closing assembly 20 includes a door 21 that is circumferentially movable along the housing 10 for opening or closing the air outlet 11. The door opening / closing drive assembly 30 includes a door opening / closing drive mechanism 31 connected to the door 21 for driving the door 21 to move. The movement of the door 21 opens or closes the air outlet 11 or adjusts its air outlet area. The door opening / closing drive mechanism 31 includes a drive motor 32 and a drive block 33 connected to the door 21 to drive the door 21 to move.

[0059] The door opening / closing drive assembly 30 is connected to the door opening / closing assembly 20 and is used to provide power to the door opening / closing assembly 20 to drive the door opening / closing assembly 20 to move, thereby closing or opening the air outlet 11. For example, the door opening / closing drive assembly 30 can be installed on the housing 10 or the heat exchange air supply assembly, such as on the air outlet frame component 40.

[0060] The door opening / closing drive mechanism 31 includes a drive motor 32 and a drive block 33. The drive motor 32 provides driving force and is connected to the drive block 33, driving the drive block 33 to move. The drive block 33 is connected to the door 21, and the moving drive block 33 drives the door 21 to move, causing the door 21 to move circumferentially, thereby moving the door 21 to either the closed or open position of the air outlet 11. Transmission via the drive block 33 eliminates the need for a rack and pinion transmission mechanism, reducing backlash during transmission and thus decreasing the resistance to movement of the door 21. This improves the efficiency of opening and closing the air outlet 11 and, compared to a rack and pinion transmission, reduces the likelihood of transmission failures in the door opening / closing drive mechanism 31.

[0061] Optionally, when the switch door 21 is in the position where the air outlet 11 is open, the switch door 21 can be located inside the housing 10. For example, the switch door 21 can be located within the receiving space defined by the housing 10 and the heat exchange and air supply assembly. For example, when the housing 10 includes the aforementioned front shell component 12 and the heat exchange and air supply assembly includes the aforementioned air outlet frame component 40, a receiving space for accommodating the switch door 21 can be defined between the front shell component 12 and the air outlet frame component 40.

[0062] According to the embodiment of the present invention, the air conditioner uses a door opening and closing drive mechanism 31 for driving the door 21 to move, which includes a drive motor 32 and a drive block 33. The drive motor 32 drives the drive block 33, causing the door 21 to move circumferentially, thereby opening or closing the air outlet 11. This eliminates the need for a gear and rack transmission mechanism, reducing the number of parts, lowering production costs, and reducing the possibility of failure of the door opening and closing drive assembly 30. Compared with a gear and rack transmission mechanism, using the drive block 33 to directly drive the door 21 reduces the backlash in the transmission process, thereby reducing the movement resistance of the door 21 and improving the efficiency of the door 21 in opening and closing the air outlet 11.

[0063] refer to Figures 9-25 According to some embodiments of this utility model, the drive block 33 is fixed to the motor shaft 321 of the drive motor 32, and the drive motor 32 is used to drive the drive block 33 to swing. By connecting the drive block 33 to the motor shaft 321, the drive motor 32 can drive the direct drive block 33, eliminating the intermediate transmission structure and simplifying the door opening and closing drive mechanism 31; furthermore, by allowing the drive block 33 to drive the door opening and closing 21 to move by swinging, it is more convenient to drive the door opening and closing 21 to move circumferentially along the housing 10.

[0064] For example, the drive block 33 can be connected to the motor shaft 321 by interference fit, or by screw connection or other connection methods.

[0065] refer to Figures 9-24 According to some embodiments of this utility model, the drive block 33 is provided with a motor shaft hole 331, and the motor shaft 321 is inserted into the motor shaft hole 331. By inserting the motor shaft 321 into the motor shaft hole 331, the drive motor 32 is connected to the drive block 33, which facilitates the connection and fixation of the motor shaft 321 and the drive block 33; and it also facilitates the disassembly of the drive motor 32 and the drive block 33, providing convenience for the maintenance and parts replacement of the door opening and closing drive mechanism 31.

[0066] For example, the motor shaft hole 331 and the motor shaft 321 can be connected by an interference fit or other connection methods. The frictional force of the interference fit between the motor shaft hole 331 and the motor shaft 321 drives the drive block 33 to swing.

[0067] According to some embodiments of this utility model, the drive block 33 is directly connected to the switch door 21. By directly connecting the drive block 33 to the switch door 21, it is convenient for the drive motor 32 to directly drive the switch door 21, thereby reducing the motion resistance of the switch door 21 and improving the efficiency of the air outlet 11 of the air conditioner's switch door 21.

[0068] For example, the drive block 33 and the switch door 21 can be connected by snap-fit, fastener, or the drive block 33 and the switch door 21 can be integrally formed.

[0069] According to some embodiments of this utility model, the drive block 33 is detachably connected to the switch door 21. For example, the detachable connection between the drive block 33 and the switch door 21 can be achieved by means of screw connection, snap-fit ​​connection, or other methods. The detachable connection between the drive block 33 and the switch door 21 facilitates the disassembly of the switch door 21, providing convenience for the maintenance and parts replacement of the air conditioner.

[0070] refer to Figures 7-11 According to some embodiments of this utility model, one of the drive block 33 and the switch door 21 has a drive column 332, and the other has a drive hole 211, into which the drive column 332 is inserted. For example, the drive block 33 may have a drive column 332, and the switch door 21 may have a drive hole 211; or, the drive block 33 may have a drive hole 211, and the switch door 21 may have a drive column 332. The drive block 33 is connected to the switch door 21 by inserting the drive column 332 into the drive hole 211. Connecting the drive block 33 to the switch door 21 through the drive column 332 and the drive hole 211 simplifies the connection method and makes it easy to operate; furthermore, it facilitates the disassembly of the switch door 21, providing convenience for the maintenance and parts replacement of the air conditioner.

[0071] refer to Figure 11According to some embodiments of this utility model, the drive block 33 includes a connecting arm 333 and a sector block 334. One end of the connecting arm 333 is connected to the motor shaft 321, and the other end of the connecting arm 333 is connected to the sector block 334, which is connected to the switch door 21. The connecting arm 333 connects the sector block 334 to the motor shaft 321, thereby driving the sector block 334 to move circumferentially along the housing 10. The connection between the sector block 334 and the switch door 21 allows the sector block 334 to drive the switch door 21 to move circumferentially along the housing 10. The shape of the sector block 334 helps to increase the contact area between the drive block 33 and the switch door 21, thus ensuring the stability of the movement of the switch door 21.

[0072] refer to Figure 11 According to some embodiments of this utility model, the door opening / closing drive assembly 30 further includes a mounting box 34, with the drive block 33 rotatably disposed within the mounting box 34, and at least a portion of the drive motor 32 located outside the mounting box 34. Specifically, "at least a portion of the drive motor 32 located outside the mounting box 34" can mean a part of the drive motor 32 is located outside the mounting box 34, or it can mean the entire drive motor 32 is located outside the mounting box 34. By placing the drive block 33 within the mounting box 34, it is beneficial to limit and protect the drive block 33, making its operation more stable. The mounting box 34 also serves to protect the drive block 33, preventing dust and other small particles from affecting its normal rotation.

[0073] refer to Figure 11 According to some embodiments of the present invention, the drive block 33 includes a connecting arm 333 and a sector block 334. One end of the connecting arm 333 is connected to the motor shaft 321, and the other end of the connecting arm 333 is connected to the sector block 334. The sector block 334 is connected to the switch door 21. A sliding column 335 is provided on the sector block 334. The mounting box 34 is provided with a first sliding groove 341. The first sliding groove 341 extends along the circumference of the housing 10. The sliding column 335 is slidably accommodated in the first sliding groove 341 along the circumference of the housing 10.

[0074] The connecting arm 333 is used to connect the sector block 334 and the motor shaft 321, thereby driving the sector block 334 to move circumferentially. The sector block 334 is connected to the switch door 21, so that the sector block 334 can drive the switch door 21 to move circumferentially along the housing 10.

[0075] The sliding column 335 on the sector block 334 is slidably accommodated in the first slide groove 341 along the circumference of the housing 10. By accommodating the sliding column 335 in the first slide groove 341, the sliding column 335 can be prevented from being misaligned by external forces, thus preventing the sliding column 335 from leaving the first slide groove 341. By enabling the sliding column 335 to slide in the first slide groove 341 along the extension direction of the first slide groove 341, the movement of the drive block 33 can be guided, so that the drive block 33 can move circumferentially along the extension direction of the first slide groove 341 in a set trajectory, thereby driving the door 21 to move circumferentially along the housing 10 according to the set trajectory.

[0076] refer to Figure 11 According to some embodiments of the present invention, the sector block 334 is provided with a plurality of sliding columns 335 spaced apart along the extension direction of the first sliding groove 341.

[0077] For example, the sector block 334 may be provided with two, three, four, five or more sliding posts 335 at intervals along the extension direction of the first slide groove 341. By providing multiple sliding posts 335, the friction of the sliding posts 335 in the first slide groove 341 can be reduced, the resistance of the door opening and closing assembly 20 can be reduced, and the sliding posts 335 can be prevented from disengaging from the first slide groove 341, thereby enhancing the stability of the sliding posts 335 during operation.

[0078] According to some embodiments of the present invention, the mounting box 34 includes a detachably connected cover 343 and a box body 344. The cover 343 and the box body 344 together define a receiving cavity 345. The box body 344 is provided with a second sliding groove 342 extending circumferentially along the housing 10. The second sliding groove 342 is located on the outer periphery of the receiving cavity 345 and on the outer periphery of the cover 343. The driving block 33 includes a driving column 332. The driving column 332 is connected to the side of the fan-shaped block 334 opposite to the connecting arm 333. The switch door 21 is provided with a driving hole 211. The connecting arm 333 and the fan-shaped block 334 are both located in the receiving cavity 345. The driving column 332 is located in the second sliding groove 342 and inserted into the driving hole 211.

[0079] For example, the cover 343 and the box 344 are detachably connected, which can be by screw connection, snap connection, or other means. This detachable connection facilitates the disassembly of parts inside the box 34, providing convenience for the maintenance and parts replacement of the door opening and closing drive assembly 30. The cover 343 and the box 344 together define a receiving cavity 345, which facilitates the reception of the connecting arm 333 and the sector block 334 of the drive block 33.

[0080] The drive column 332 and drive hole 211 are connected to facilitate the connection between the drive block 33 and the switch door 21, so that the drive block 33 can drive the switch door 21 to move. The connection method of the drive column 332 and drive hole 211 also facilitates the disassembly of the switch door 21, providing convenience for the maintenance and parts replacement of the air conditioner.

[0081] Furthermore, a second sliding groove 342 extending circumferentially along the housing 10 is provided on the box body 344. The second sliding groove 342 is located on the outer periphery of the receiving cavity 345 and on the outer periphery of the cover body 343, so that the drive column 332 is located in the second sliding groove 342 and inserted into the drive hole 211. In this way, when connecting the drive hole 211 on the switch door 21 to the drive column 332 on the drive block 33, since it is done in an open space, there is no need to open the mounting box 34 body, which facilitates the connection operation between the drive hole 211 on the switch door 21 and the drive column 332 on the drive block 33, and facilitates the connection and disassembly operation between the switch door 21 and the drive block 33.

[0082] refer to Figures 7-11 According to some embodiments of the present invention, the switch door 21 is provided with a guide post 212, which is slidably accommodated in the second slide groove 342 along the extension direction of the second slide groove 342.

[0083] The guide post 212 serves a guiding function. It is slidably accommodated in the second slide groove 342 along its extension direction, which can prevent the guide post 212 from being misaligned due to external forces and prevent it from detaching from the second slide groove 342. By allowing the guide post 212 to slide within the second slide groove 342 along its extension direction, the movement of the guide post 212 can be guided, enabling it to move circumferentially along the extension direction of the second slide groove 342 along a set trajectory, thereby driving the door 21 to move circumferentially along the housing 10 according to the set trajectory.

[0084] refer to Figures 4-8 According to some embodiments of the present invention, the door opening and closing assembly 20 includes two door opening and closing doors 21. When the door opening and closing assembly 20 is in the position of closing the air outlet 11, the two door opening and closing doors 21 are arranged in the left and right direction and together close the air outlet 11.

[0085] The door opening and closing assembly 20 includes two movable doors 21 along the circumference of the housing 10. The movement of the two doors 21 can close or open the air outlet 11. With a fixed width of the air outlet 11 in the left-right direction, the movement of the two doors 21 along the circumference of the housing 10 during the process of closing or opening the air outlet 11 by the door opening and closing assembly 20 can shorten the travel distance of a single door 21, thereby reducing the time it takes for the door opening and closing assembly 20 to open or close the air outlet 11.

[0086] For example, the two switches 21 can move toward each other to close the air outlet 11; or, the two switches 21 can move away from each other to open the air outlet 11. When the two switches 21 are in the position of opening the air outlet 11, the two switches 21 can be located on the left and right sides of the air outlet 11 respectively.

[0087] For example, when the air conditioner is turned on, the drive motors 32 in the two door opening and closing drive mechanisms 31 are driven to rotate the drive block 33 in the mounting box 34. The drive block 33, which is connected to the door opening and closing assembly 20, drives the door opening and closing 21 from the position where the air outlet 11 is closed to the position where the air outlet 11 is open, so that the door opening and closing assembly 20 moves to the position where the air outlet 11 is open. When the air conditioner is turned off, the drive motors 32 in the two door opening and closing drive mechanisms 31 are driven to rotate the drive block 33 in the mounting box 34. The drive block 33, which is connected to the door opening and closing assembly 20, drives the door opening and closing 21 from the position where the air outlet 11 is open to the position where the air outlet 11 is closed, so that the door opening and closing assembly 20 moves to the position where the air outlet 11 is closed.

[0088] refer to Figure 4 According to some embodiments of the present invention, the door opening and closing drive assembly 30 includes two door opening and closing drive mechanisms 31, one of which is connected to one of the door opening and closing mechanisms 21, and the other of which is connected to the other door opening and closing mechanism 21.

[0089] When the door opening and closing assembly 20 includes two doors 21, the door opening and closing drive assembly 30 includes two door opening and closing drive mechanisms 31. One of the two door opening and closing drive mechanisms 31 is connected to one of the doors 21, and the other door opening and closing drive mechanism 31 is connected to the other door 21. This allows each door 21 to be driven by an independent door opening and closing drive mechanism 31, so that the movement of the two doors 21 can be independent of each other, and the independent control of a single door opening and closing mechanism 21 can be achieved.

[0090] For example, when the required air outlet area is low, one of the switch doors 21 can be positioned with the air outlet 11 open, and the other switch door 21 can be positioned with the air outlet 11 closed, thus concentrating the air outlet 11. For example, when the airflow from the air conditioner needs to be relatively concentrated at the front left of the air conditioner, the left switch door 21 can be positioned with the air outlet 11 open, and the right switch door 21 can be positioned with the air outlet 11 closed. For example, when the airflow from the air conditioner needs to be relatively concentrated at the front right of the air conditioner, the right switch door 21 can be positioned with the air outlet 11 open, and the left switch door 21 can be positioned with the air outlet 11 closed. For example, when a large air outlet area and air volume are required, both switch doors 21 can be positioned with the air outlet 11 open.

[0091] refer to Figures 4-11 According to some embodiments of the present invention, each switch door 21 corresponds to two switch door drive mechanisms 31. The two switch door drive mechanisms 31 corresponding to each switch door 21 are located at the upper and lower ends of the switch door 21 and are both connected to the switch door 21.

[0092] In each of the two door opening and closing mechanisms 31 corresponding to each door opening and closing door 21, one door opening and closing mechanism 31 is located at the upper end of the door opening and closing door 21 and is connected to the upper end of the door opening and closing door 21, and the other door opening and closing mechanism 31 is located at the lower end of the door opening and closing door 21 and is connected to the lower end of the door opening and closing door 21.

[0093] By setting a door opening and closing drive mechanism 31 at each of the upper and lower ends of each door 21, it is beneficial to keep the upper and lower ends of the door 21 synchronized during movement, so that the door 21 can operate smoothly.

[0094] refer to Figures 9-24 According to some embodiments of the present invention, the door opening and closing drive assembly 30 further includes two mounting boxes 34, with the two upper door opening and closing drive mechanisms 31 mounted in the upper mounting box 34, and the two lower door opening and closing drive mechanisms 31 mounted in the lower mounting box 34.

[0095] The mounting box 34 is used to install the door opening and closing drive mechanism 31, and can accommodate the drive block 33 of the door opening and closing drive mechanism 31. The mounting box 34 facilitates the installation of multiple components of the door opening and closing drive mechanism 31 into a single unit.

[0096] By mounting the two upper door opening and closing drive mechanisms 31 in the upper mounting box 34, and the two lower door opening and closing drive mechanisms 31 in the lower mounting box 34, two door opening and closing drive mechanisms 31 located on the same side in the vertical direction can share a single mounting box 34. This reduces the number of mounting boxes 34 and makes the installation of multiple door opening and closing drive mechanisms 31 more convenient. For example, two door opening and closing drive mechanisms 31 located on the same side in the vertical direction can be mounted in the same mounting box 34, and then the mounting box 34 with two door opening and closing drive mechanisms 31 can be fixed to the housing 10 or the heat exchange and air supply assembly.

[0097] The mounting box 34 can be installed and fixed on the air outlet frame component 40. For example, the mounting box 34 located on the upper side is installed and fixed on the top of the air outlet frame component 40, and the mounting box 34 located on the lower side is installed and fixed on the bottom of the air outlet frame component 40.

[0098] For example, when the air conditioner is turned on, the drive motor 32 located on the left side of the upper mounting box 34 and the drive motor 32 located on the left side of the lower mounting box 34 in the door opening and closing drive assembly 30 drive the left door 21 to move circumferentially to the left, and the drive motor 32 located on the right side of the upper mounting box 34 and the drive motor 32 located on the right side of the lower mounting box 34 in the door opening and closing drive assembly 30 drive the right door 21 to move circumferentially to the right.
