Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and more specifically, to an air conditioner with an automatic filter cleaning structure. Background Technology
[0002] An air conditioner's filter is an indispensable component, typically located at the air inlet to filter and block dust and other pollutants from the air. However, after prolonged use, dust accumulates on the filter, causing blockages that impede ventilation, reduce cooling and heating efficiency, and ultimately increase energy consumption. Furthermore, some dust may pass through the filter and adhere to the heat exchanger and other internal components of the air conditioner. Therefore, it is necessary to manually clean the filter after a period of use. Utility Model Content
[0003] The problem solved by this invention is that air conditioner filters accumulate dust after prolonged use, preventing proper air exchange.
[0004] To address the aforementioned problems, this utility model provides an air conditioner with an automatic filter cleaning structure. The air conditioner includes: a housing with an air intake at its top; a filter disposed inside the housing and below the air intake; and a dustproof device comprising a cleaning brush, a flexible curtain, a roller, a first dust collection box, and a second dust collection box. The first dust collection box is located below the filter and is used to collect dust from the filter. The second dust collection box is located below the flexible curtain and is used to collect dust from the flexible curtain. The cleaning brush has detachable brush parts for sweeping away dust from the filter or the flexible curtain. The roller is rotatably mounted on the housing and is connected to the flexible curtain, allowing the flexible curtain to be wound around the roller.
[0005] The technical effects achieved by adopting this solution are as follows: By setting up a flexible curtain and covering the filter screen, dust is prevented from adhering to the filter screen and from entering the air conditioner; the roller is used to store the flexible curtain; the first dust collection box and the second dust collection box can collect the swept dust; the brushes on the cleaning brush are detachable, so they can be repeatedly cleaned and are easy to install, with a long service life.
[0006] Furthermore, the cleaning brush includes a first cleaning brush, which is disposed above the filter screen and is always in contact with the filter screen, moving laterally along the filter screen.
[0007] The technical effects achieved by adopting this solution are as follows: the first cleaning brush can move back and forth along the filter screen, cleaning the dust on the filter screen during the movement, preventing dust from clogging the filter screen and improving its efficiency.
[0008] Furthermore, the cleaning brush also includes a second cleaning brush, which is fixed to one side of the filter screen. When the air conditioner is in a stopped state, the second cleaning brush and the first cleaning brush are engaged with each other.
[0009] The technical effect achieved by adopting this solution is that the second cleaning brush can be structurally engaged with the first cleaning brush, so that the first and second cleaning brushes can be installed more stably on the air conditioner, achieving the technical effect of mutual positioning.
[0010] Furthermore, the other end of the flexible curtain away from the roller is fixedly connected to one end of the first cleaning brush, and the first cleaning brush drives the flexible curtain to retract or unfold when it moves laterally.
[0011] The technical effects achieved by adopting this solution are as follows: the flexible curtain can move laterally left and right as the first cleaning brush moves. The flexible curtain can also move simultaneously when the first cleaning brush removes dust from the filter screen. Therefore, the flexible curtain is directly driven by the first cleaning brush, avoiding the need for additional drive devices. The structure is simple and the components move in a continuous manner, resulting in a low failure rate.
[0012] Furthermore, the flexible curtain is positioned horizontally above the filter screen. The flexible curtain has a retracted position and an unfolded position. In the retracted position, the first cleaning brush moves laterally to the side closer to the roller to allow normal air intake. In the unfolded position, the first cleaning brush moves laterally to the side away from the roller to cover the air inlet.
[0013] The technical effects achieved by adopting this solution are as follows: the flexible curtain can be retracted or unfolded by rotating the roller. When retracted, the air inlet can operate normally, and the flexible curtain can avoid the air inlet; when unfolded, the flexible curtain can cover the air inlet to prevent dust from entering the air conditioner.
[0014] Furthermore, the first dust collection box is disposed on one side of the air intake, and the second dust collection box is disposed on the other side of the air intake opposite to the first dust collection box, and the second dust collection box is connected to the roller.
[0015] The technical effects achieved by adopting this solution are as follows: By symmetrically arranging the dust collection boxes on both sides of the air intake, installation space can be saved. During the disassembly of the first and second dust collection boxes, they can be directly moved downwards for disassembly, making the disassembly process simple and easy to operate.
[0016] Furthermore, the cleaning brush also includes a third cleaning brush, which is installed between the roller and the second dust collection box. When the air conditioner is in operation, the first cleaning brush moves laterally away from the second cleaning brush, causing the flexible curtain to be stored in the roller. The dust on the flexible curtain is accumulated in the second dust collection box through the third cleaning brush.
[0017] The technical effects achieved by adopting this solution are as follows: By installing a third cleaning brush, the dust on the top of the flexible curtain can be removed and sent to the second dust collection box during the process of the flexible curtain being stored on the roller. This can prevent the flexible curtain from accumulating a large amount of dust on top due to long-term use. Moreover, the dust cleaning process is a self-cleaning process, avoiding manual operation and making it convenient to use.
[0018] Furthermore, the second cleaning brush is fixedly installed above the first dust collection box. When the filter screen is automatically cleaned, the first cleaning brush moves laterally towards the second cleaning brush, and the dust on the filter screen is accumulated in the first dust collection box through the second cleaning brush.
[0019] The technical effects achieved by adopting this solution are as follows: the first cleaning brush removes dust from the filter screen during the air conditioner's shutdown process, and the dust is collected in the first dust collection box by the second cleaning brush, avoiding manual cleaning. Furthermore, the air conditioner can perform a self-cleaning process every time it stops running, preventing dust accumulation on the filter screen.
[0020] Furthermore, a fixed bracket for installing the dustproof device is provided inside the outer casing.
[0021] The technical effects achieved by adopting this solution are: the fixed bracket can support the dustproof device, making the dustproof device more stable and increasing its service life.
[0022] Furthermore, the housing includes a panel that is detachable and located at the front of the housing, and can be opened outwards to facilitate cleaning of the first dust collection box and the second dust collection box.
[0023] The technical effects achieved by adopting this solution are as follows: By setting a detachable panel, the disassembly process becomes more convenient. After disassembly, the internal dustproof device can be cleaned and the first and second dust collection boxes can be emptied, making the operation simple.
[0024] In summary, by adopting the technical solution of this utility model, the following technical effects can be achieved:
[0025] (1) By installing a flexible curtain above the filter screen, the filter screen can be covered when the air conditioner is not running, preventing dust from adhering to the filter screen and dust from entering the machine;
[0026] (2) By setting a second cleaning brush and a first dust collection box, the dust on the filter screen can be automatically cleaned when the air conditioner stops;
[0027] (3) By setting a third cleaning brush and a second dust collection box, the dust on the flexible curtain can be automatically cleaned when the flexible curtain is stored in the roller. Attached Figure Description

Detailed Implementation
[0037] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0038] See Figures 1-7 This utility model provides an air conditioner with an automatic filter cleaning structure. The air conditioner includes: a housing 10 with an air intake at the top; a filter 20 disposed inside the housing 10 and below the air intake 11; and a dustproof device 30, which includes a cleaning brush 31, a flexible curtain 32, a roller 33, a first dust collection box 341, and a second dust collection box 342. The first dust collection box 341 is located below the filter 20 and is used to collect dust from the filter 20. The second dust collection box 342 is located below the flexible curtain 32 and is used to collect dust from the flexible curtain 32. The cleaning brush 31 is provided with detachable brush parts for sweeping away dust from the filter 20 or the flexible curtain 32. The roller 33 is rotatably disposed on the housing 10 and is connected to the flexible curtain 32 so that the flexible curtain 32 can be wound around the roller 33.
[0039] In this embodiment, by setting a flexible curtain 32 and covering the filter screen 20, dust can be prevented from adhering to the filter screen 20 and from entering the air conditioner; the roller 33 is used to store the flexible curtain 32; the first dust collection box 341 and the second dust collection box 342 can collect the dust that has been swept down; the brush parts on the cleaning brush 31 are detachable, so they can be repeatedly cleaned and are easy to install, and have a long service life.
[0040] It should be noted that when the cleaning brush is sweeping away dust, some dust may fall directly into the dust collection box 341 and dust collection box 342 after falling off the filter screen 20. Therefore, most of the dust will eventually fall into the dust collection box, avoiding the need for manual cleaning again.
[0041] In one specific embodiment, the cleaning brush 31 includes a first cleaning brush 311, which is disposed above the filter screen and is always in contact with the filter screen 20, moving laterally along the filter screen 20.
[0042] Preferably, the first cleaning brush 311 is provided with soft bristles that can partially enter the filter screen 20, thereby increasing the contact area between the filter screen 20 and the first cleaning brush 311. The first cleaning brush 311 can move back and forth along the filter screen 20, and can clean the dust on the filter screen 20 during the movement, avoiding dust clogging the filter screen and improving its efficiency.
[0043] In one specific embodiment, the cleaning brush 31 further includes a second cleaning brush 312, which is fixed to one side of the filter screen 20. When the air conditioner is in a stopped state, the second cleaning brush 312 and the first cleaning brush 311 are engaged with each other. See also Figure 6 The diagram shows an enlarged view of the first cleaning brush 311 in its stopped state. Preferably, the brush handle of the first cleaning brush 311 is a columnar structure with a rectangular cross-section, and the first cleaning brush 311 is provided with bristles. The second cleaning brush 312 is a fixed component and cannot move relative to it. In the stopped state, the second cleaning brush 312 can be structurally engaged with the first cleaning brush 311, so that the first and second cleaning brushes can be more stably installed on the air conditioner, achieving the technical effect of mutual positioning.
[0044] In one specific embodiment, the other end of the flexible curtain 32 away from the roller 33 is fixedly connected to one end of the first cleaning brush 311, and the first cleaning brush 311 drives the flexible curtain 32 to retract or unfold when it moves laterally.
[0045] It should be noted that, Figure 1 This is the unfolded state of the flexible curtain 32. Figure 2 In the retracted state of the flexible curtain 32, the installation of the roller 33 allows the flexible curtain 32 to not occupy additional space when retracted, saving storage space for the air conditioner. Furthermore, the flexible curtain 32 can move laterally left and right as the first cleaning brush 311 moves. The flexible curtain 32 can also move simultaneously when the first cleaning brush 311 removes dust from the filter screen 20. Therefore, the flexible curtain 32 is directly driven by the first cleaning brush 311, avoiding the need for additional drive devices. The structure is simple, the components move smoothly, and the failure rate is low.
[0046] In one specific embodiment, the flexible curtain 32 is positioned horizontally above the filter screen 20. The flexible curtain 32 has a retracted position and an unfolded position. In the retracted position, the first cleaning brush 311 moves laterally to the side close to the roller 33 to allow normal air intake. In the unfolded position, the first cleaning brush 311 moves laterally to the side away from the roller 33 to cover the air intake 11.
[0047] In this embodiment, the flexible curtain 32 can be retracted or unfolded by rotating the roller 33. When retracted, the air inlet 11 can operate normally and the flexible curtain 32 can avoid the air inlet 11. When unfolded, the flexible curtain 32 can cover the air inlet 11 to prevent dust from entering the air conditioner.
[0048] In one specific embodiment, the first dust collection box 341 is disposed on one side of the air intake 11, and the second dust collection box 342 is disposed on the other side of the air intake 11 opposite to the first dust collection box 341. The second dust collection box 342 is connected to the roller 33.
[0049] In this embodiment, by symmetrically arranging the dust collection boxes on both sides of the air intake 11, installation space can be saved. During the disassembly of the first dust collection box 341 and the second dust collection box 342, they can be disassembled by simply moving them downwards. Therefore, the disassembly process is simple and easy to operate.
[0050] In one specific embodiment, the cleaning brush 31 further includes a third cleaning brush 313, which is installed between the roller 33 and the second dust collection box 342. When the air conditioner is in operation, the first cleaning brush 311 moves laterally away from the second cleaning brush 312, causing the flexible curtain 32 to be stored in the roller 33. The dust on the flexible curtain 32 is accumulated in the second dust collection box 342 through the third cleaning brush 313.
[0051] It should be noted that, see Figure 5 The roller 33 and the third cleaning brush 313 move in opposite directions. For example, the roller 33 retracts the flexible curtain 32 in a clockwise direction, while the third cleaning brush 313 rotates in a counterclockwise direction. This can give the bristles on the third cleaning brush 313 greater force, which helps the dust to detach from the flexible curtain 32 and enter the second dust collection box 342 through the third cleaning brush 313, thereby improving the cleaning effect.
[0052] In this embodiment, by installing the third cleaning brush 313, the dust on the top of the flexible curtain 32 can be removed and sent to the second dust collection box 342 during the process of the flexible curtain 32 being stored in the roller 33. This can prevent the flexible curtain 32 from accumulating a large amount of dust on its top due to long-term use, and the dust cleaning process is a self-cleaning process, avoiding manual operation and making it convenient to use.
[0053] In one specific embodiment, the second cleaning brush 312 is fixedly installed above the first dust collection box 341. When the filter screen is automatically cleaned, the first cleaning brush 311 moves laterally toward the direction of the second cleaning brush 312, and the dust on the filter screen 20 is accumulated in the first dust collection box 341 through the second cleaning brush 312.
[0054] It should be noted that, in Figure 7 The diagram shows an enlarged view of the first cleaning brush 311 in operation. When the first cleaning brush 311 moves close to the second cleaning brush 312, the dust on the filter screen 20 accumulates on the bristles of the first cleaning brush 311. The dust attached to the bristles falls into the first dust collection box 341 as the first cleaning brush 311 moves. When the second cleaning brush 312 combs the bristles of the first cleaning brush 311, the second cleaning brush 312 applies a vertical force to the first cleaning brush 311, making it easier for the dust on the bristles to fall off.
[0055] In this embodiment, the first cleaning brush 311 removes dust from the filter screen 20 during the air conditioner's shutdown process, and the dust is collected in the first dust collection box 341 by the second cleaning brush 312, avoiding manual cleaning. Furthermore, the air conditioner can perform self-cleaning once every time it stops running, thus preventing dust accumulation on the filter screen 20.
[0056] In one specific embodiment, a mounting bracket for installing the dustproof device 30 is provided inside the housing 10. The mounting bracket can support the dustproof device 30, thereby making the dustproof device 30 more stable and increasing the service life of the air conditioner.
[0057] In one specific embodiment, the housing 10 includes a panel 40, which is detachable and located at the front of the housing 10. The panel 40 can be opened outward to facilitate cleaning of the first dust collection box 341 and the second dust collection box 342.
[0058] In this embodiment, by providing a detachable panel 40, the disassembly process can be made more convenient. After disassembly, the internal dustproof device 30 can be cleaned and the first dust collection box 341 and the second dust collection box 342 can be emptied, making the operation simple.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
