DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] This embodiment provides an air conditioner, such as Figures 1-4As shown, it includes a shell, at least one of the panel 100 and the back panel of the shell is provided with an air outlet 110 and a dustproof component 200, the dustproof component 200 includes a driving component 210, a dustproof curtain 220 and a gravity pull member 230, the top end of the dustproof curtain 220 is connected to the driving component 210, and the bottom end is connected to the gravity pull member 230, and the dustproof curtain 220 can move upward to an avoidance position avoiding the corresponding air outlet 110 under the drive of the driving component 210 along the first driving direction, and move downward to a blocking position blocking the air outlet 110 under the drive of the driving component 210 along the second driving direction and the gravity pull of the gravity pull member 230, wherein the second driving direction is opposite to the first driving direction.

[0024] The air conditioner provided in this embodiment includes a dustproof component 200 for shielding the air outlet 110 for dust protection. When the air conditioner needs to be turned on for temperature adjustment, the driving component 210 is started. The driving component 210 overcomes the gravity of the gravity pulling member 230 along the first driving direction to pull the dustproof curtain 220 up to the top of the air outlet 110, and the dustproof curtain 220 accordingly reaches the avoidance position to avoid blocking the air outlet 110, thereby ensuring the normal inflow and outflow of air from the air outlet 110; after the temperature adjustment is completed, the air conditioner is on standby or stopped, and the driving component 210 is started to run along the second driving direction opposite to the first driving direction. The driving component 210 no longer tightens the dustproof curtain 220 to make it in a relaxed state, and the gravity pulling member 230 pulls the bottom of the dustproof curtain 220 The downward gravity applied at the end can pull the bottom end of the dust curtain 220 to move downward in front of the air outlet 110 until the bottom end of the dust curtain 220 reaches the bottom position of the air outlet 110, and the dust curtain 220 accordingly reaches the blocking position that can block the air outlet 110, thereby shielding the air outlet from dust, and correspondingly reducing the pollution caused by external dust to the air outlet 110, air guide components, air duct components, etc. on the inside of the dust curtain 220 when the air conditioner is stopped or in standby state, thereby improving the cleanliness of the air conditioner, reducing the adverse effects of the covered dust in the air duct on the fan, evaporator, condenser, etc. when the air conditioner is running, or blowing the covered dust into the room to affect the user experience, thereby correspondingly improving the use effect and experience of the air conditioner.

[0025] In the air conditioner provided by this embodiment, the provision of the dustproof assembly 200 ensures the normal operation of the air conditioner and shields the air outlet 110 from dust when it is stopped or in standby mode, thereby improving the use effect and user experience of the air conditioner. The dustproof curtain 220 does not need to be manually disassembled and assembled by the user, thereby improving the operation convenience of the dustproof assembly 200 and the convenience of use of the air conditioner. In addition, it is only necessary to install the driving component 210 above the air outlet 110, and the bottom end of the dustproof curtain 220 is connected to a gravity pulling member 230 with a certain weight. Then, the downward gravity action of the gravity pulling member 230 and the upward pulling force of the driving component 210 can be used to move the dustproof curtain 220 between the avoidance position and the shielding position, without installing another driving component 210 below the air outlet 110 or a linkage member connected to the upper driving component 210. The structure is simple and the functionality is strong. Accordingly, while ensuring that the air conditioner has a dustproof function, the overall simplicity of the air conditioner is improved.

[0026] Specifically, if Figure 1 As shown, the air vent 110 is an air outlet 110 provided on the panel 100. Of course, in other embodiments, the air vent may also be an air inlet or fresh air vent 110 provided on the back panel of the indoor unit. In addition, the air vent 110 may be an air inlet 110 or air outlet 110 of an outdoor unit. Specifically, the gravity pull member 230 may be made of a metal material with a high density, such as stainless steel or iron.

[0027] Optionally, in this embodiment, if Figure 1 and Figure 3 As shown, a vertically extending baffle 300 is provided on at least one horizontal side of the air outlet 110. A guide gap 310 exists between the baffle 300 and the outer end surface of the air outlet 110. The gravity pull member 230 includes a crossbeam 231, which includes a connecting section 231a corresponding to the bottom end of the dust curtain 220. A guide section 231b extends from the connecting section 231a toward the guide gap 310, and the guide section 231b is slidably inserted into the guide gap 310. From a perspective facing the air outlet 110, the baffle 300 is located on the left or right side of the air outlet 110; alternatively, there are two baffles 300, one on the left side of the air outlet 110 and the other on the right side. Preferably, the baffle 300 does not block the front of the air outlet 110, thereby ensuring the effective air inlet and outlet area of ​​the air outlet 110.

[0028] During the up and down movement of the dust curtain 220, the entire crossbeam 231 exerts a downward gravity on the dust curtain 220, and the guide gap 310 can limit the front and rear directions of the up and down movement of the guide section 231b (based on the perspective facing the air outlet 110), and accordingly restrict the movement of the bottom end of the dust curtain 220, so that the entire dust curtain 220 can move up and down smoothly in front of the air outlet 110, thereby ensuring that the driving component 210 and the gravity pull member 230 can pull the dust curtain 220 up and down smoothly. 0 driving smoothness, reducing the dust curtain 220 bottom end fluttering affecting the driving component 210 and the gravity pulling member 230 pulling the dust curtain 220; at the same time, when the dust curtain 220 is in the blocking position, the guide gap 310 limits the bottom end of the dust curtain 220 to the position of the guide gap 310 by limiting the guide section 231b, thereby ensuring that the dust curtain 220 effectively blocks the air outlet 110 and reducing the dust curtain 220 from fluttering and failing to effectively block the air outlet 110. In addition, in this embodiment, the baffle 300 is spaced apart from the front end surface of the air outlet 110 to form a guide gap 310. During installation, it is only necessary to determine the relative position of the baffle 300 and the front end surface of the air outlet 110, and there is no need to provide a limiting groove on the baffle 300. This improves the processing convenience of the baffle 300 on the basis of achieving the guiding and limiting of the crossbeam 231. Moreover, the radial dimension of the crossbeam 231 is greater than the thickness of the dust curtain 220. During the up and down movement of the dust curtain 220, the side walls of the crossbeam 231 in the front and rear directions first collide with the side walls of the guide gap 310, and the probability of the dust curtain 220 contacting the side walls of the guide gap 310 is small, thereby reducing the wear on the dust curtain 220 caused by the guiding process, and reducing the occurrence of the situation where the friction is large and the dust curtain 220 is easily stuck or even stuck due to direct guiding and limiting the edge of the dust curtain 220.

[0029] In this embodiment, Figure 3 As shown, the end of the guide segment 231b facing away from the connecting segment 231a is connected to a limiting beam 232. The limiting beam 232 is slidably engaged with the end surface of the guide gap 310 facing away from the air outlet 110. The cooperation between the limiting beam 232 and the end surface of the guide gap 310 can limit the left-right movement of the limiting beam 232 and the crossbeam 231 (from the perspective of the air outlet 110), and accordingly limit the left-right position of the dust curtain 220 during its up-and-down movement, thereby further reducing the left-right deviation of the dust curtain 220 during its up-and-down movement, which could cause the gravity pull member 230 to be caught, and thus further ensure the normal movement of the dust curtain 220. At the same time, when the dust curtain 220 is in the blocking position, the cooperation between the limiting beam 232 and the end surface of the guide gap 310 can limit the left-and-right position of the dust curtain 220, ensuring that the dust curtain 220 effectively blocks the air outlet 110.

[0030] Specifically, in this embodiment, the outer diameter of the limiting beam 232 is smaller than the width of the guide gap 310. The guide gap 310 allows the limiting beam 232 to pass through. When the connection between the gravity pull member 230 and the bottom end of the dust curtain 220 becomes loose or other problems occur, and the bottom end of the dust curtain 220 requires maintenance, if the blocking bars 300 are provided on both the left and right sides of the air outlet 110 and the limiting beams 232 are provided at both ends of the crossbeam 231, the crossbeam 231 can be rotated circumferentially until the limiting beams 232 are parallel to the vertical cross section of the guide gap 310 in the left and right directions. The crossbeam 231 is then rotated so that one end of the longitudinal direction rises and the other end falls until the limiting beams 232 at both ends are disengaged from the corresponding guide gap 310. The gravity pull member 230 can then be removed from the guide gap 310 for maintenance. After maintenance is completed, the gravity pull member 230 can be installed into the guide gap 310 using the same method. In the case where the baffle 300 is only set on one side of the air outlet 110 and the limiting beam 232 is set at one end of the beam 231, the beam 231 can be rotated circumferentially until the limiting beam 232 is parallel to the vertical section in the left and right directions of the guide gap 310, and then the beam 231 is moved away from the end of the limiting beam 232. The limiting beam 232 can be pulled out from the guide gap 310, and the gravity pulling member 230 can be taken out of the guide gap 310 for maintenance operations; after the maintenance is completed, the gravity pulling member 230 can be installed into the guide gap 310 in the same way, thereby improving the maintenance convenience of the dustproof component 200 and correspondingly improving the convenience of using the air conditioner.

[0031] Optionally, in this embodiment, if Figure 1 and Figure 2 As shown, panel 100 is provided with a receiving hole 120 above air outlet 110. Receiving box 400 is inserted into receiving hole 120. The bottom plate of receiving box 400 is provided with a cloth outlet 410. The driving component 210 is housed within receiving box 400, and the bottom end of the dust curtain extends downward through cloth outlet 410. The provision of receiving box 400 provides isolation and protection for driving component 210, reducing damage to driving component 210 caused by external factors such as collisions. This ensures the connection between driving component 210 and dust curtain, as well as the normal operation of driving component 210, and accordingly ensures the normal use of dustproof assembly 200. Furthermore, the provision of receiving box 400 shields driving component 210, enhancing the neatness of the air conditioner's appearance.

[0032] Specifically, in this embodiment, Figure 4As shown, the cloth outlet 410 includes a cloth outlet area 411 for the passage of the crossbeam 231 and a disassembly area 412 for the passage of the limiting beam 232. The top of the disassembly area 412 is detachably covered with a baffle 420, and the baffle 420 and the disassembly area 412 form a retaining groove 430. A dust curtain extends downward through the cloth outlet area 411. When the dust curtain needs to be cleaned or maintained, the baffle 420 can be removed, and the gravity pull member 230 can be pulled upward through the cloth outlet 410. The dust curtain can then be removed and cleaned. Similarly, during installation, the limiting beam 232 is aligned with the disassembly area 412 and the crossbeam 231 is aligned with the cloth outlet area 411. The gravity pull member 230 is then moved downward through the cloth outlet 410, the top of the dust curtain 220 is connected to the drive component 210, and the baffle 420 is then connected to the bottom plate to seal the top of the disassembly area 412. Among them, the baffle 420 and the disassembly and assembly area 412 form a baffle 430 with the groove facing downward. When the driving component 210 drives the dust curtain 220 to move upward, when the limiting beam 232 is stuck in the baffle 430 and abuts against the bottom wall of the baffle 420, it indicates that the dust curtain 220 has moved up to the avoidance position, and the driving component 210 is closed to stop the continued driving of the dust curtain.

[0033] Preferably, an upper pressure sensor may be provided at the bottom of the baffle 420, and both the upper pressure sensor and the drive component 210 are communicatively connected to the main controller of the air conditioner. When the main controller receives a power-on signal from the air conditioner, indicating a need to start the air conditioner for temperature adjustment, the main controller simultaneously or before starting the air conditioner also controls the drive component 210 to move the dust curtain 220 upward. When the gravity pull member 230 moves upward and abuts the baffle 420, the gravity pull member 230 contacts the upper pressure sensor, which then signals that it has reached the avoidance position. The main controller then shuts down the drive component 210 accordingly, thereby accurately, quickly, and intelligently starting the drive component 210 without requiring the user to manually start and stop the drive component 210, thereby improving the ease of use of the air conditioner.

[0034] Specifically, in this embodiment, Figure 2As shown, the driving component 210 includes a reel 211 rotatably connected to the accommodating box 400 and a driving motor 213 installed on the accommodating box 400. The top end of the dust curtain is wound on the shaft section of the reel 211 corresponding to the cloth outlet 410. One end of the reel 211 is connected to a worm section 212. The driving end of the driving motor 213 is connected to a worm gear 214, and the worm gear 214 is meshed with the worm section 212. This is one of the specific forms of the driving component 210. When the air conditioner needs to be used, the driving motor 213 is started, and the output shaft of the driving motor 213 rotates in a first driving direction. The worm gear 214 rotates synchronously with the output shaft and drives the worm section 212 to rotate, thereby driving the reel 211 to rotate in the direction of winding the dust curtain 220. Accordingly, the dust curtain 220 and the gravity pull member 230 located outside the air outlet 110 continuously move upward and wind around the reel 211 until the bottom end of the dust curtain 220 reaches a position higher than The avoidance position at the upper end of the air outlet 110; when the air conditioner is not in use, the driving component 210 is started, and the output shaft of the driving component 210 rotates in a second driving direction opposite to the first driving direction, and the worm gear 214, the worm segment 212 and the reel 211 rotate in opposite directions accordingly, and the reel 211 loosens the dust curtain wound thereon, and the gravity pulling member 230 acts on the dust curtain to tighten the bottom end of the dust curtain downward until the gravity pulling member 230 is lower than the lower end of the air outlet 110, thereby pulling the dust curtain down to the blocking position.

[0035] Among them, the driving component 210 adopts the cooperation of the worm gear 214 and the worm segment 212, and the driving motor 213 and the worm gear 214 are located on the radial side of the worm segment 212 rather than the axial end. On the basis of realizing the driving of the scroll 211, the space occupied by the driving motor 213 and the like on the axial end of the scroll 211 is reduced, and the space in the front and rear directions of the accommodating box 400 is fully utilized accordingly, while the space occupied in the left and right directions is reduced, thereby ensuring the width requirements of the air outlet 110 along the left and right directions.

[0036] In this embodiment, Figure 1 and Figure 3 As shown, the air outlet 110 is covered with a grille 500, and the gravity pull member 230 is located outside the grille 500. The grille 500 can provide preliminary filtering and protection for the air outlet 110, reducing the possibility of users accidentally inserting their hands into the air outlet 110 and causing damage to it, thereby improving the safety of the air conditioner. At the same time, the gravity pull member 230 pulls the bottom end of the dust curtain 220 to be located outside the grille 500. When the dust curtain 220 is in the blocking position, it can also block the grille 500, thereby reducing the pollution caused by dust falling on the grille 500 and the possibility of dust on the grille 500 being blown into the room or sucked into the air duct when the air conditioner is running.

[0037] Optionally, in this embodiment, if Figure 3As shown, the bottom edge of the air outlet 110 extends outward to form a receiving platform 130. A lower pressure sensor is provided at the corresponding position of the receiving platform 130 and the gravity pulling member 230. The pressure sensor and the driving component 210 are both communicatively connected to the main controller of the air conditioner. When the main controller receives a shutdown or standby signal from the air conditioner, indicating that the air conditioner needs to be shut down, the main controller simultaneously or subsequently controls the activation of the driving component 210 to release the dust curtain 220. The gravity pull member 230 thereby pulls the dust curtain 220 downward. When the gravity pull member 230 moves downward to abut against the receiving platform 130, it abuts against the downward pressure sensor. The downward pressure sensor feeds back a signal indicating that it has reached the blocking position to the main controller, and the main controller accordingly deactivates the driving component 210, causing the dust curtain 220 to droop. This ensures that the dust curtain 220 effectively blocks the air outlet 110 and reduces the possibility that the dust curtain 220 is lowered too far and bends outward, failing to effectively block the air outlet 110. At the same time, the provision of the downward pressure sensor enables the main controller to accurately, quickly, and intelligently activate the driving component 210 without the user having to manually start and stop the driving component 210, thereby further improving the convenience of using the air conditioner.

[0038] Specifically, in this embodiment, Figure 3 As shown, a receiving groove 131 is provided at the receiving platform 130 at a position corresponding to the gravity pull member 230. The receiving groove 131 matches the gravity pull member 230, and a downward pressure sensor is mounted at the bottom of the receiving groove 131. When the gravity pull member 230 pulls the bottom end of the dust curtain 220 downward to the blocking position, the gravity pull member 230 is embedded in the receiving groove 131. Based on the feedback of the downward pressure sensor to the main controller regarding the position, the receiving groove 131 can limit the gravity pull member 230, thereby improving the positional stability of the gravity pull member 230 in the avoidance position, and correspondingly ensuring the positional stability of the bottom end of the dust curtain 220, thereby ensuring the dust-blocking effect of the dust curtain 220 on the air outlet 110.
